  According to the air conditioning system and the air conditioning method capable of humidification and sterilization according to the present invention, when the humidity measured by each humidity sensor does not reach the set humidity, a vaporization humidification mechanism or a spray humidification mechanism is created by these air conditioners. The first air conditioning operation (first air conditioning operation) for humidifying the conditioned air is performed individually for each air conditioning room for a predetermined period, and when the humidity measured by each humidity sensor reaches the set humidity, Since the second air-conditioning operation (second air-conditioning operation) for supplying the air-conditioned air to the air-conditioned room without humidification is performed for each air-conditioned room individually for a predetermined period, the humidity of these air-conditioned rooms is optimally maintained.

The functional water is supplied from the functional water generation device to the functional water storage tank. Since a constant amount of functional water is constantly stored in the functional water storage tank, the functional water is not depleted in the functional water storage tank, and the first sterilization operation (first sterilization operation by depleting the functional water) ) Or the second sterilization operation (second sterilization operation) can be prevented. The air conditioning system and method can be used to reliably sterilize the humidification mechanism using functional water when the vaporization humidification mechanism or spray humidification mechanism of each air conditioner is required. Because it can be used in a clean state, bacteria and foul odors are not mixed into the conditioned air from these humidifying mechanisms, and clean conditioned air that has been humidified and has moderate humidity or clean that has moderate humidity without being humidified Conditioned air can be supplied to each air-conditioned room.

The system and the air conditioning method can sterilize each drain pan using functional water when it is necessary to sterilize the drain pan of each air conditioner, and the drain pan can be used in a clean state. The air conditioning system and air conditioning method can use each drain pan in a clean state as well as the vaporizing humidification mechanism or the spray humidification mechanism. Thus, clean air-conditioned air having an appropriate humidity and clean air-conditioned air having an appropriate humidity without being humidified can be supplied to each air-conditioning room.

Depending on the functional water supply line, the humidification mechanism, and the chemical resistance of the drain pan, when the first functional water having a strong sterilizing effect is always used, the functional water supply line, the humidification mechanism, Although drain pans hurt, the functional water supply line, the humidification mechanism thereof, and the drain pan pain can be prevented by appropriately using the second functional water having a weak sterilizing effect. In the air conditioning system and the air conditioning method, when a large amount of bacteria are generated in each air conditioning room, a strong sterilization operation can be performed to sterilize the air conditioning room with the first functional water having a strong sterilizing effect. When there is little generation | occurrence | production of microbe in, it can carry out weak sterilization operation and can sterilize those air-conditioning rooms with the 2nd functional water which has a weak sterilization effect.

Operation) until a strong sterilization operation (strong sterilization operation) is performed for a predetermined period of time after the first air conditioning operation or the second air conditioning operation (first air conditioning operation or second air conditioning operation) is performed. Driving (weak sterilization Because it is longer than the predetermined period until the operation), the strong sterilization operation (strong sterilization operation) is not frequently performed, and the functional water supply line is appropriately used by using the second functional water having a weak sterilization effect. And those humidification mechanism, those drain pan pain can be prevented.

By operating the air conditioner 12 in the second sterilization operation (second sterilization operation) in the strong sterilization operation (strong sterilization operation), the conditioned air containing the first functional water component having a strong sterilization action is supplied to the air conditioning chamber 11. Since the air in the air conditioning chamber 11 is sterilized by the sterilization action (sterilization effect) of the first functional water, not only the humidifying element 22 and the drain pan 24 can be sterilized but also the air conditioning chamber 11 can be sterilized. .

  In the air conditioning system 10A (air conditioning method), when the humidity measured by the humidity sensor 17 does not reach the set humidity, the humidifying element 22 humidifies the conditioned air produced by the air conditioner 12 (first air conditioning operation). ), And when the humidity measured by the humidity sensor 17 has reached the set humidity, the second air conditioning operation (second air conditioning operation) for supplying the air conditioned air produced by the air conditioner 12 to the air conditioned room 11 without humidification ) Can be supplied from the air conditioner 12 to the air conditioning chamber 11 and air sterilized in the humidifying element 22 can be sterilized by the first air conditioning operation (first). The air conditioning operation) or the second air conditioning operation (second air conditioning operation) is stopped and the sterilization operation (sterilization operation) for sterilizing the humidifying element 22 and the drain pan 24 is performed. The Renpan 24 can be clean.

  The air conditioning system 10A (air conditioning method) humidifies the conditioned air using humidified water and can supply the conditioned air having an appropriate humidity to the air conditioned room 11, as well as the humidifying element 22 of the air conditioner 12. When the drain pan 24 needs to be sterilized, the humidifying element 22 and the drain pan 24 can be sterilized using the first functional water or the second functional water, and the humidifying element 22 and the drain pan 24 can be used in a clean state. it can. Since the air conditioning system 10A (air conditioning method) can use the humidifying element 22 and the drain pan 24 in a clean state, the air and the odor are not mixed from the humidifying element 22 and the drain pan 24 into the conditioned air. Clean air-conditioned air having an appropriate humidity or clean air-conditioned air having an appropriate humidity without being humidified can be supplied to the air-conditioning room 11. The air conditioning system 10A (air conditioning method) performs the first function by performing a second sterilization operation (second sterilization operation) for supplying conditioned air containing components of the first function water or the second function water to the air conditioning chamber 11. Since the conditioned air containing the water or the component of the second functional water is supplied to the air conditioning chamber 11 and the air in the air conditioning chamber 11 is sterilized by the sterilizing action (sterilizing effect) of the first functional water or the second functional water, humidification is performed. Not only can the element 22 and the drain pan 24 be sterilized, but the air-conditioned room 11 can be sterilized, and the air-conditioned room 11 can be used in a clean state.

In the system 10B of FIG. 5, two functional water supply lines 14 and 15 are installed, but the number of functional water supply lines is not particularly limited, and only one functional water supply line is installed. Alternatively, three or more functional water supply lines may be installed.

  The humidity sensors 17A and 17B are installed in the air conditioning chambers 11A and 11B. The humidity sensors 17A and 17B are connected to the controller 16 via the interface 18. The humidity sensors 17 </ b> A and 17 </ b> B measure the humidity inside the air conditioning chambers 11 </ b> A and 11 </ b> B and transmit the measured measured humidity to the controller 16. The set humidity and set temperature inside the air conditioning rooms 11 </ b> A and 11 </ b> B are transmitted to the controller 16.

  These air conditioners 12A and 12B supply conditioned air humidified by vaporization-type humidification (drop-type humidification) or conditioned air that is not humidified to the respective air-conditioning chambers 11A and 11B. In the control units of the air conditioners 12A and 12B, a heat medium is caused to flow through the cooling coil 20 or the heating coil 21 according to the set temperature transmitted from the controller 16 to control the temperatures of the air conditioning rooms 11A and 11B. The humidifying water supply line 13 is formed by a first humidifying water electromagnetic valve 30, two second humidifying water electromagnetic valves 31 </ b> A and 31 </ b> B, two check valves 32, and a humidifying water supply pipe 33. The proximal end portion of the humidifying water supply pipe 33 is connected to a water source pipe. The front end of the humidifying water supply pipe 33 is branched into two and connected to the upper end 27 of the vaporizing humidifying element 22.

  The humidified water first electromagnetic valve 30 is attached to the humidified water supply pipe 33, and its control unit is connected to the controller 16 via the interface 18. These check valves 32 are attached to the humidifying water supply pipe 33 to prevent the backflow of the humidifying water. The second humidifying water second electromagnetic valves 31 </ b> A and 31 </ b> B are attached to the humidifying water supply pipe 33, and a control unit thereof is connected to the controller 16 via the interface 18.

  The first functional water supply line 14 and the second functional water supply line 15 are branched into two and are connected to the humidifying elements 22 of the first and second air conditioners 12A and 12B. First and second switching 1 are the same as those in FIG. 1 except that the electromagnetic valves 47A and 47B for use are installed. The supply pipes 38 and 44 connected to the upper end portion 27 of the humidifying element 22 installed in the air conditioner 12A are provided with a first switching electromagnetic valve 47A, and are connected to the upper end portion 27 of the humidifying element 22 installed in the air conditioner 12B. A first switching electromagnetic valve 47B is installed in the connected supply pipes 38 and 44. The control units of the switching solenoid valves 47A and 47B are connected to the controller 16 via an interface. The hard disk of the controller 16 stores the time schedule shown in FIG. 2 as in the system 10A of FIG.

  Based on FIG. 7, the first air conditioning operation (first air conditioning operation) in the air conditioning system 10B (air conditioning method) will be described as follows. In addition, the same time (period) as the system 10A of FIG. 1 shall be set as the stop time (stop period) and operation time (operation period) of the 1st and 2nd water pumps 36 and 42. Further, it is assumed that the first functional water is stored in the first functional water storage tank 35 and the second functional water is stored in the second functional water storage tank 41.

  When the measured humidity measured by each of the humidity sensors 17A and 17B has not reached the set humidity when the first and second water pumps 36 and 42 are stopped, the air conditioning system 10B (air conditioning method) 1 air-conditioning operation (1st air-conditioning operation) is implemented. In the first air conditioning operation (first air conditioning operation), each air conditioner 12A, 12B adjusts the cooling coil 20 or the heating coil 21 so that the temperature of each air conditioning room 11A, 11B becomes the set temperature transmitted from the controller 16. To do. Further, the humidifying water supply line 13 supplies the humidifying water to each humidifying element 22, and the humidifying element 22 humidifies the conditioned air produced by the air conditioners 12A and 12B.

  In the first air conditioning operation (first air conditioning operation), functional water is not supplied from the first and second functional water supply lines 14 and 15. In the first air conditioning operation (first air conditioning operation), the controller 16 holds the valve mechanism of the humidified water first electromagnetic valve 30 in an open state. Further, the controller 16 transmits a stop command to the first and second water pumps 36 and 42, and the first and second water pumps 36 and 42 hold the stopped state according to the stop command transmitted from the controller 16.

  When the controller 16 compares the measured humidity measured by the humidity sensors 17A and 17B with the set humidity and determines that the measured humidity has not reached the set humidity, the controller 16 opens the valve mechanisms of the second electromagnetic valves 31A and 31B for humidified water. To do. Moreover, while the measured humidity does not reach the set humidity, the valve mechanisms of the humidified water second electromagnetic valves 31A and 31B are continuously opened. When the valve mechanism of the humidifying second electromagnetic valves 31A and 31B is opened, as shown by an arrow L1 in FIG. 7, the humidifying water (tap water) passes through the humidifying water supply pipe 33 and the upper end of the humidifying element 22 is reached. Water is supplied from the portion 27 to the entire area of the element 22. The humidifying element 22 retains humidified water and drains the excess to the drain pan 24. The conditioned air produced by the air conditioners 12A and 12B comes in contact with the humidified water while passing through the humidifying element 22 that retains the humidified water, and becomes humidified conditioned air. The humidified conditioned air is supplied from the air supply duct 26 to the air conditioned rooms 11A and 11B as indicated by an arrow L2 in FIG. The first air conditioning operation (first air conditioning operation) is performed until the measured humidity reaches the set humidity.

When the first and second water pumps 36 and 42 are at the stop time and the measured humidity measured by the humidity sensors 17A and 17B reaches the set humidity (first air conditioning operation (first air conditioning operation)). After the execution, including the case where the measured humidity reaches the set humidity), the air conditioning system 10B (air conditioning method) performs the second air conditioning operation (second air conditioning operation).

  In the second air conditioning operation (second air conditioning operation), the air conditioners 12A and 12B are cooled by the cooling coil 20 or the heating so that the temperatures of the first and second air conditioning chambers 11A and 11B become the set temperatures transmitted from the controller 16. Adjust the coil 21. Further, the supply of the humidified water from the humidified water supply line 13 to the humidifying element 22 is stopped, and the conditioned air produced by the air conditioners 12A and 12B is supplied to the air conditioned rooms 11A and 11B.

  When the controller 16 compares the measured humidity measured by the humidity sensors 17A and 17B with the set humidity and determines that the measured humidity has reached the set humidity, the controller 16 closes the valve mechanisms of the second electromagnetic valves 31A and 31B for humidified water. . Further, while the measured humidity reaches the set humidity, the valve mechanisms of the humidified water second electromagnetic valves 31A and 31B are kept closed. In the second air conditioning operation (second air conditioning operation), the valve mechanisms of the humidified water second electromagnetic valves 31A and 31B are closed, and the supply of humidified water (tap water) to the humidifying element 22 is stopped. Air-conditioned air is supplied from the air supply duct 25 to the air-conditioned rooms 11A and 11B. The second air conditioning operation (second air conditioning operation) is performed while the measured humidity reaches the set humidity, and when the measured humidity does not reach the set humidity, the first air conditioning operation (first air conditioning operation) is performed again. Is done.

  FIG. 8 is a diagram for explaining an example of weak sterilization operation (weak sterilization operation) in the air conditioning system 10B (air conditioning method). An example of weak sterilization operation (weak sterilization operation) in the air conditioning system 10B (air conditioning method) will be described based on FIG. The controller 16 determines whether it is in the stop time (stop period) of the first and second water pumps 36 and 42. One week has passed since the first air-conditioning operation (first air-conditioning operation) or the second air-conditioning operation (second air-conditioning operation) was performed. When the two water pumps 42 are not in the stop time (in operation time), the air conditioning system 10B (air conditioning method) performs the weak sterilization operation (weak sterilization operation) by the second functional water supply line 15.

In the weak sterilization operation (weak sterilization operation), the controller 16 transmits a close command to the first humidified water electromagnetic valve 30 and the first humidified water electromagnetic valve 30 closes the valve mechanism. Thereby, the supply of the humidified water from the humidified water supply line 13 is stopped. In the weak sterilization operation (weak sterilization operation), the controller 16 determines that the second water pump 42 is in operation time, transmits an operation command to the second water pump 42, the pump 42 is turned on, and the pump 42 is turned on. Operate. Further, the controller 16 determines that it is in the stop time of the first water pump 36, transmits a stop command to the first water pump 36, the power of the pump 36 remains OFF, and the pump 36 holds the stop state. Further, the controller 16 transmits an opening command to the switching first and second electromagnetic valves 47A and 47B, and the electromagnetic valves 47A and 47B open the valve mechanism.

  When the second water pump 42 is operated and the valve mechanisms of the electromagnetic valves 47A and 47B are opened, the second functional water stored in the second functional water storage tank 41 is stored in the tank as shown by an arrow L3 in FIG. 41 is supplied from the upper end 27 of the humidifying element 22 to the entire area of the element 22 through the functional water second supply pipe 44. Further, the second functional water is supplied to the drain pan 24 through the supply pipe 52. In the humidifying element 22, the second functional water is retained, and the excess is drained to the drain pan 24.

  In the weak sterilization operation (weak sterilization operation), the humidifying element 22 is sterilized with the second functional water, and the drain pan 24 is sterilized with the second functional water. When the measured water level transmitted from the second water level sensor 45 is less than the set water level, the control unit of the second functional water generating device 40 generates the second functional water and generates the generated second functional water as the second functional water. The water is supplied to the water storage tank 41, and the amount of water stored in the second function water in the second function water storage tank 41 is recovered to the set water level.

  When 30 minutes have passed since the operation of the second water pump 42 and the operation time of the second water pump 42 has elapsed, the controller 16 determines that the second water pump 42 is at a stop time, and the second water pump The stop command is transmitted to 42, the power supply of the pump 42 is turned off, and the pump 42 holds the stopped state. The controller 16 transmits an opening command to the first humidifying water electromagnetic valve 30, and the first humidifying water electromagnetic valve 30 opens the valve mechanism. Further, the controller 16 transmits a closing command to the switching first and second electromagnetic valves 47A and 47B, and the electromagnetic valves 47A and 47B close the valve mechanism. After 30 minutes have passed since the second water pump 42 is operated, either the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) is performed immediately after the pump 42 stops. . In the weak sterilization operation (weak sterilization operation) of FIG. 8, the first sterilization operation (first sterilization operation) in which the controller 16 stops the operation of the first and second air conditioners 12A and 12B is performed in the same manner as that of FIG. Or the controller 16 may perform a second sterilization operation (second sterilization operation) in which the operation of the first and second air conditioners 12A and 12B is continued.

  In the first sterilization operation (first sterilization operation) in which the operation of the first and second air conditioners 12A and 12B is stopped in the weak sterilization operation (weak sterilization operation), air conditioning is performed from the air conditioners 12A and 12B to the air conditioning chambers 11A and 11B. The supply of air is stopped, the second functional water remains in the humidifying element 22 and the drain pan 24, and the conditioned air containing the component of the second functional water is not supplied to the air conditioned rooms 11A and 11B. By stopping the operation of the air conditioners 12A and 12B in the first sterilization operation (first sterilization operation) in the weak sterilization operation (weak sterilization operation), the second function water can be retained in the humidifying element 22 and the drain pan 24, Even if bacteria are generated (bred) in the humidifying element 22 or the drain pan 24, the humidifying element 22 or the drain pan 24 can be surely sterilized using the second functional water. Moreover, the air-conditioning air containing the component of 2nd function water is not supplied to air-conditioning room 11A, 11B, and the filling of air-conditioning room 11A, 11B with the odor of 2nd function water can be prevented.

  In the second sterilization operation (second sterilization operation) in which the operation of the first and second air conditioners 12A and 12B is continued in the weak sterilization operation (weak sterilization operation), air conditioning is performed from the air conditioners 12A and 12B to the air conditioning chambers 11A and 11B. Air is continuously supplied, and conditioned air containing the component of the second functional water is supplied to the air conditioned rooms 11A and 11B. By operating the air conditioners 12A and 12B in the second sterilization operation (second sterilization operation) in the weak sterilization operation (weak sterilization operation), the conditioned air containing the component of the second functional water is supplied to the air conditioning chambers 11A and 11B. Since the air in the air conditioning chambers 11A and 11B is sterilized by the sterilization action (sterilization effect) of the second functional water, not only the humidifying element 22 and the drain pan 24 can be sterilized but also the air conditioning chambers 11A and 11B are sterilized. can do.

  FIG. 9 is a diagram illustrating an example of a strong sterilization operation (strong sterilization operation) in the air conditioning system 10B (air conditioning method). An example of the strong sterilization operation (strong sterilization operation) in the air conditioning system 10B (air conditioning method) will be described based on FIG. The controller 16 determines whether it is in the stop time (stop period) of the first and second water pumps 36 and 42. One month has passed since the first air-conditioning operation (first air-conditioning operation) or the second air-conditioning operation (second air-conditioning operation) was performed. When it is not in the stop time of 1 water supply pump 36 (it is in operation time), in air-conditioning system 10B (air-conditioning method), strong sterilization operation (strong sterilization operation) by the 1st functional water supply line 14 is carried out.

In the strong sterilization operation (strong sterilization operation), the controller 16 transmits a close command to the first humidified water electromagnetic valve 30, and the first humidified water electromagnetic valve 30 closes the valve mechanism. Thereby, the supply of the humidified water from the humidified water supply line 13 is stopped. In the strong sterilization operation (strong sterilization operation), the controller 16 determines that the operation time of the first water pump 36 is in operation, transmits an operation command to the first water pump 36, the pump 36 is turned on, and the pump 36 is turned on. Operate. Further, the controller 16 determines that the second water pump 42 is in a stop time, transmits a stop command to the second water pump 42, the pump 42 remains off, and the pump 42 remains stopped. Further, the controller 16 transmits an opening command to the switching first and second electromagnetic valves 47A and 47B, and the electromagnetic valves 47A and 47B open the valve mechanism.

  When the first water pump 36 is operated and the valve mechanisms of the electromagnetic valves 47A and 47B are opened, the first functional water stored in the first functional water storage tank 35 is stored in the tank as shown by an arrow L4 in FIG. 35 is supplied from the upper end 27 of the humidifying element 22 to the entire area of the element 22 through the functional water first supply pipe 38. Further, the first functional water is supplied to the drain pan 24 through the supply pipe 52. In the humidifying element 22, the first functional water is retained and the excess is drained to the drain pan 24.

  In the strong sterilization operation (strong sterilization operation), the humidifying element 22 is sterilized with the first functional water, and the drain pan 24 is sterilized with the first functional water. When the actually measured water level transmitted from the first water level sensor 39 is less than the set water level, the control unit of the first functional water generating device 34 generates the first functional water and generates the generated first functional water as the first functional water. The water is supplied to the water storage tank 35, and the amount of water stored in the first function water in the first function water storage tank 35 is recovered to the set water level.

  When 30 minutes have elapsed since the operation of the first water pump 36 and the operation time of the first water pump 36 has elapsed, the controller 16 determines that the first water pump 36 is at a stop time, and the first water pump 36 A stop command is transmitted to 36, the power supply of the pump 36 is turned off, and the pump 36 holds the stopped state. Further, the controller 16 transmits an opening command to the first humidified water electromagnetic valve 30, and the first humidified water electromagnetic valve 30 opens the valve mechanism. Further, the controller 16 transmits a closing command to the switching first and second electromagnetic valves 47A and 47B, and the electromagnetic valves 47A and 47B close the valve mechanism. Thirty minutes have passed since the first water pump 36 was operated, and either the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) is performed immediately after the pump 36 stops. . In the strong sterilization operation (strong sterilization operation) of FIG. 9, the first sterilization operation (first sterilization operation) in which the controller 16 stops the operation of the first and second air conditioners 12A and 12B is performed as in FIG. Or the controller 16 may perform a second sterilization operation (second sterilization operation) in which the operation of the first and second air conditioners 12A and 12B is continued.

  In the first sterilization operation (first sterilization operation) in which the operation of the first and second air conditioners 12A and 12B is stopped in the strong sterilization operation (strong sterilization operation), air conditioning is performed from the air conditioners 12A and 12B to the air conditioning chambers 11A and 11B. The supply of air is stopped, the first functional water stays in the humidifying element 22 and the drain pan 24, and the conditioned air containing the component of the first functional water is not supplied to the air conditioned rooms 11A and 11B. By stopping the operation of the air conditioners 12A and 12B in the first sterilization operation (first sterilization operation) in the strong sterilization operation (strong sterilization operation), the humidifying element 22 and the drain pan 24 retain the first functional water having a strong sterilizing action. Even if bacteria are generated (propagated) in the humidifying element 22 or the drain pan 24, the humidifying element 22 or the drain pan 24 can be reliably sterilized using the first functional water. Moreover, the air-conditioning air containing the component of the 1st function water is not supplied to the air-conditioning room 11, and the odor of the 1st function water can be prevented from being filled in the air-conditioning rooms 11A and 11B.

  In the second sterilization operation (second sterilization operation) in which the operation of the first and second air conditioners 12A and 12B is continued in the strong sterilization operation (strong sterilization operation), air conditioning from the air conditioners 12A and 12B to the air conditioning chambers 11A and 11B. Air is continuously supplied, and conditioned air containing the component of the first functional water is supplied to the air conditioned rooms 11A and 11B. By operating the air conditioners 12A and 12B in the second sterilization operation (second sterilization operation) in the strong sterilization operation (strong sterilization operation), the conditioned air containing the component of the first functional water having a strong sterilization effect is supplied to the air conditioning room 11A. 11B and the air in the air conditioning chambers 11A and 11B is sterilized by the sterilization action (sterilization effect) of the first functional water, so that the humidifying element 22 and the drain pan 24 can be sterilized, and the air conditioning chamber 11A 11B can also be sterilized.

  In the air conditioning system 10B (air conditioning method), when the humidity measured by the humidity sensors 17A and 17B does not reach the set humidity, each humidifying element 22 humidifies the conditioned air produced by the air conditioners 12A and 12B. When the operation (first air-conditioning operation) is performed and the humidity measured by the humidity sensors 17A and 17B reaches the set humidity, the air-conditioned rooms 11A are not humidified without humidifying the air-conditioned air produced by the air-conditioners 12A and 12B. Since the second air conditioning operation (second air conditioning operation) to be supplied to 11B is performed, conditioned air having an appropriate humidity can be supplied from each air conditioner 12A, 12B to each air conditioned room 11A, 11B. When sterilizing bacteria that have grown (bred) in the element 22 or the drain pan 24, the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) is stopped. Since implementing the sterilization operation (sterilization operation) to sterilize the humidifying element 22 and the drain pan 24 Te, their humidifier element 22 and their drain pan 24 it can be a clean state.

  The air conditioning system 10B (air conditioning method) humidifies the conditioned air using humidified water and can supply the conditioned air having appropriate humidity to each of the air conditioned rooms 11A and 11B. When the 12B humidifying element 22 or drain pan 24 needs to be sterilized, each humidifying element 22 or drain pan 24 can be sterilized using functional water, and each humidifying element 22 or drain pan 24 is used in a clean state. Can do. Since the air conditioning system 10B (air conditioning method) can use the humidifying element 22 and the drain pan 24 in a clean state, the air and the odor are not mixed into the conditioned air from each humidifying element 22 and the drain pan 24, and the humidification is performed. Thus, clean air-conditioned air having an appropriate humidity and clean air-conditioned air having an appropriate humidity without being humidified can be supplied to the air-conditioning rooms 11A and 11B. The air conditioning system 10B (air conditioning method) functions by performing a second sterilization operation (second sterilization operation) for supplying conditioned air containing components of the first functional water or the second functional water to the air conditioning chambers 11A and 11B. Air-conditioned air containing water components is supplied to the air-conditioning chambers 11A and 11B, and the air in the air-conditioning chambers 11A and 11B is sterilized by the sterilization effect (sterilization effect) of the functional water, so that the humidifying element 22 and the drain pan 24 are sterilized. In addition, the air conditioning rooms 11A and 11B can be sterilized, and the air conditioning rooms 11A and 11B can be used in a clean state.

  FIG. 10 is a configuration diagram of an air conditioning system 10B different from FIG. The system 10B of FIG. 10 is different from that of FIG. 6 in that the first switching electromagnetic valve 47A extends to the water supply pipe 38 extending toward the air conditioner 12A (first air conditioner) and connected to the upper end 27 of the humidifying element 22. The second switching solenoid valve 47B is installed in the water supply pipe 44 that is installed and extends toward the air conditioner 12A and is connected to the upper end 27 of the humidifying element 22, toward the air conditioner 12B (second air conditioner). A third switching electromagnetic valve 47C is installed in the water supply pipe 38 that extends to the upper end portion 27 of the humidifying element 22 and extends toward the air conditioner 12B to the water supply pipe 44 that extends to the upper end portion 27 of the humidifying element 22. The fourth switching electromagnetic valve 47D is provided. The first to fourth switching electromagnetic valves 47 </ b> A to 47 </ b> D are connected to the controller 16 through the interface 18.

  Since other configurations in the system 10B shown in FIG. 10 are the same as those in the system 10B in FIG. 6, the same reference numerals as those in FIG. 6 are given, and the explanation of the system 10B in FIG. Is omitted. The system 10B of FIG. 10 installs the first to fourth switching electromagnetic valves 47A to 47D in the water supply pipes 38 and 44, and uses the first to fourth switching electromagnetic valves 47A to 47D. By switching the supply of the two-function water, it is possible to perform a weak sterilization operation (weak sterilization operation) in the air conditioner 12A and a strong sterilization operation (strong sterilization operation) in the air conditioner 12B. Moreover, the strong sterilization operation (strong sterilization operation) can be performed in the air conditioner 12A, and the weak sterilization operation (weak sterilization operation) can be performed in the air conditioner 12B. In addition, it cannot be overemphasized that either weak sterilization operation (weak sterilization operation) or strong sterilization operation (strong sterilization operation) can be performed in air conditioner 12A, 12B. Further, when the controller 16 performs a first sterilization operation (first sterilization operation) in which the operation of the first and second air conditioners 12A and 12B is stopped, or the controller 16 performs the first and second air conditioners 12A and 12B. There is a case where the second sterilization operation (second sterilization operation) for continuing the operation is performed.

  Since the system 10B of FIG. 10 can perform a weak sterilization operation (weak sterilization operation) on one of the air conditioners 12A and 12B and a strong sterilization operation (strong sterilization operation) on the other side, the degree of bacterial propagation The sterilization operation (sterilization operation) of either strength or weakness can be applied to each of the air conditioners 12A and 12B depending on the years of use of the humidifying element 22 and the drain pan 24 and the new and old conditions of the air conditioners 12A and 12B. The humidifying element 22 and the drain pan 24 of the machines 12A and 12B can be made clean.

  FIG. 11 is a configuration diagram of an air conditioning system 10C shown as another example. The system 10C of FIG. 11 is different from that of FIG. 1 in that an odor sensor 46 (odor sensor) is installed in the air conditioner 12, and other configurations are the same as those of the system 10A of FIG. 1, the same reference numerals as those in FIG. 1 are attached, and the description of the system 10A in FIG.

  The air conditioning system 10C (air conditioning method) includes an air conditioning chamber 11 having a predetermined volume, an air conditioner 12 that air-conditions air, a humidified water supply line 13, and first and second functional water supply lines 14 and 15 (first function). The water supply line to the n-th functional water supply line), the controller 16 (control device), the humidity sensor 17, and the odor sensor 46 (odor sensor).

  In the system 10C of FIG. 11, two functional water supply lines 14 and 15 are installed, but the number of functional water supply lines is not particularly limited, and only one functional water supply line is installed. Alternatively, three or more functional water supply lines may be installed. The humidity sensor 17 is installed inside the air conditioning room 11 and is connected to the controller 16 via the interface 18. The set humidity and set temperature inside the air conditioning room 11 are transmitted to the controller 16. The control unit of the air conditioner 12 controls the temperature of the air conditioning chamber 11 by flowing a heat medium through the cooling coil 20 or the heating coil 21 according to the set temperature transmitted from the controller 16.

  The odor sensor 46 is installed inside the air conditioner 12. The odor sensor 46 is connected to the controller 16 via the interface 18. The odor sensor 46 measures the odor of the conditioned air that has flowed out of the blower 23 and transmits the measured odor to the controller 16. The odor sensor 46 uses a metal oxide semiconductor sensor and measures the odor level (odor intensity) by the reaction between the odor and the sensor. The odor sensor 46 is a standard gas (ammonia gas, amine gas, aldehyde gas, aromatic gas, ester gas, hydrocarbon gas, organic acid gas, sulfur gas, hydrogen sulfide gas). Similarity and odor contribution are analyzed by comparison with.

  The hard disk of the controller 16 stores the operating time of the first and second water pumps 36 and 42, stores the set odor level (the set odor intensity), and the first air conditioning operation (first The comparison between the measured odor level and the set odor level is resumed (measurement by the odor sensor 46) after the air conditioning operation) or the second air conditioning operation (second air conditioning operation) is carried out (after the operation of the pumps 36 and 42 is stopped). Is stored until it is substantially restarted). It is assumed that the operating time of the first and second water pumps 36 and 42 is set to 30 minutes. The set odor level includes a first set odor level as a reference for performing a weak sterilization operation (weak sterilization operation) and a second set odor level as a reference for performing a strong sterilization operation (strong sterilization operation). For example, it is assumed that 800 is set as the first set odor level and 1200 is set as the second set odor level. It is assumed that 30 minutes is set as the time until the comparison between the measured odor level and the set odor level is resumed. The operation time of the pumps 36 and 42, the set odor level, and the time until the odor sensor 46 is restarted can be freely set via the numeric keypad unit.

  The controller 16 compares the measured humidity transmitted from the humidity sensor 17 with the set humidity, and compares the measured odor level transmitted from the odor sensor 46 with the set first and second set odor levels. The measured odor level is compared with the set odor level, and the measured humidity and the set humidity are compared. As a result, the measured odor level does not reach the set odor level, and the measured humidity does not reach the set humidity. In the air conditioning system 10C (air conditioning method), the first air conditioning operation (first air conditioning operation) is performed. Since the first air conditioning operation (first air conditioning operation) is the same as that of the system 10A of FIG. 1, the description of the system 10A of FIG.

  When the measured odor level does not reach the set odor level as a result of comparing the measured odor level and the set odor level and comparing the measured humidity with the set humidity, and the measured humidity has reached the set humidity In the air conditioning system 10C (air conditioning method), the second air conditioning operation (second air conditioning process) is performed. Since the second air conditioning operation (second air conditioning operation) is the same as that of the system 10A of FIG. 1, the description of the system 10A of FIG.

  FIG. 12 is a diagram illustrating an example of weak sterilization operation (weak sterilization operation) in the air conditioning system 10C (air conditioning method). Based on FIG. 12, an example of the weak sterilization operation (weak sterilization operation) in the air conditioning system 10C (air conditioning method) will be described as follows. As a result of comparing the measured odor level transmitted from the odor sensor 46 with the set odor level, the measured odor level has reached the first set odor level and the measured odor level has not reached the second set odor level. In the air conditioning system 10C (air conditioning method), a weak sterilization operation (weak sterilization operation) by the second functional water supply line 15 is performed.

In the weak sterilization operation (weak sterilization operation), even if the measured odor is transmitted from the odor sensor 46, the controller 16 does not compare the measured odor level with the set odor level (substantially measure the odor sensor 46). Stop). In the weak sterilization operation, the controller 16 transmits a closing command to the first humidifying water electromagnetic valve 30, and the first humidifying water electromagnetic valve 30 closes the valve mechanism. Thereby, the supply of the humidified water from the humidified water supply line 13 is stopped. In the weak sterilization operation, the controller 16 transmits an operation command to the second water pump 42, the power of the pump 42 is turned on, and the pump 42 is operated. Moreover, the controller 16 transmits a stop command to the first water pump 36, the power supply of the pump 36 remains OFF, and the pump 36 maintains the stopped state.

  When the second water pump 42 is operated, as indicated by an arrow L3 in FIG. 12, the second functional water stored in the second functional water storage tank 41 is humidified from the tank 41 through the second supply pipe 44 for functional water. It is supplied from the upper end 27 of the element 22 to the entire area of the element 22. Further, the second functional water is supplied to the drain pan 24 through the supply pipe 52. Note that when the second functional water is not supplied to the drain pan 24, the valve mechanism of the gate valve 53 is closed. In the humidifying element 22, the second functional water is retained, and the excess is drained to the drain pan 24. In the weak sterilization operation (weak sterilization operation), the humidifying element 22 is sterilized with the second functional water, and the drain pan 24 is sterilized with the second functional water.

  When the measured water level transmitted from the second water level sensor 45 is less than the set water level, the control unit of the second functional water generating device 40 generates the second functional water and generates the generated second functional water as the second functional water. The water is supplied to the water storage tank 41, and the amount of water stored in the second function water in the second function water storage tank 41 is recovered to the set water level.

  When 30 minutes have passed since the operation of the second water pump 42 and the operation time of the second water pump 42 has elapsed, the controller 16 determines that the second water pump 42 is at a stop time, and the second water pump The stop command is transmitted to 42, the power supply of the pump 42 is turned off, and the pump 42 holds the stopped state. The controller 16 transmits an opening command to the first electromagnetic valve 30 for humidified water, and the first electromagnetic valve 30 for humidified water opens the valve mechanism. 30 minutes have passed since the operation of the second water pump 42, and either the first air conditioning operation or the second air conditioning operation is performed immediately after the pump 42 is stopped.

  The controller 16 transmits the measurement transmitted from the odor sensor 46 after 30 minutes have elapsed since the first air conditioning operation or the second air conditioning operation was performed (after 30 minutes have elapsed since the second water pump 42 stopped). The comparison between the odor level and the set odor level is resumed (measurement by the odor sensor 46 is substantially resumed). In the weak sterilization operation (weak sterilization operation) of FIG. 11, the controller 16 performs a first sterilization operation (first sterilization operation) in which the operation of the air conditioner 12 is stopped, as in FIG. However, a second sterilization operation (second sterilization operation) in which the operation of the air conditioner 12 is continued may be performed.

  FIG. 13 is a diagram illustrating an example of a strong sterilization operation (strong sterilization operation) in the air conditioning system 10C (air conditioning method). An example of a strong sterilization operation (strong sterilization operation) in the air conditioning system 10C (air conditioning method) will be described based on FIG. As a result of comparing the measured odor level transmitted from the odor sensor 46 with the set odor level, when the measured odor level reaches the second set odor level, the air conditioning system 10C (air conditioning method) supplies the first function water. A strong sterilization operation (strong sterilization operation) by line 14 is performed.

In the strong sterilization operation (strong sterilization operation), even if the measured odor is transmitted from the odor sensor 46, the controller 16 does not compare the measured odor level with the set odor level (substantially measure the odor sensor 46). Stop). In the strong sterilization operation (strong sterilization operation), the controller 16 transmits a close command to the first humidified water electromagnetic valve 30, and the first humidified water electromagnetic valve 30 closes the valve mechanism. Thereby, the supply of the humidified water from the humidified water supply line 13 is stopped. In the strong sterilization operation (strong sterilization operation), the controller 16 transmits an operation command to the first water pump 36, the pump 36 is turned on, and the pump 36 is operated. Moreover, the controller 16 transmits a stop command to the second water supply pump 42, the power of the pump 42 remains OFF, and the pump 42 maintains the stopped state.

  When the first water pump 36 is operated, as indicated by an arrow L4 in FIG. 13, the first functional water stored in the first functional water storage tank 35 is humidified from the tank 35 through the functional water first supply pipe 38. It is supplied from the upper end 27 of the element 22 to the entire area of the element 22. Further, the first functional water is supplied to the drain pan 24 through the supply pipe 52. Note that when the first functional water is not supplied to the drain pan 24, the valve mechanism of the gate valve 53 is closed. In the humidifying element 22, the first functional water is retained and the excess is drained to the drain pan 24. In the strong sterilization operation (strong sterilization operation), the humidifying element 22 is sterilized with the first functional water, and the drain pan 24 is sterilized with the first functional water.

  When the actually measured water level transmitted from the first water level sensor 39 is less than the set water level, the control unit of the first functional water generating device 34 generates the first functional water and generates the generated first functional water as the first functional water. The water is supplied to the water storage tank 35, and the amount of water stored in the first function water in the first function water storage tank 35 is recovered to the set water level.

  When 30 minutes have elapsed since the operation of the first water pump 36 and the operation time of the first water pump 36 has elapsed, the controller 16 determines that the first water pump 36 is at a stop time, and the first water pump 36 A stop command is transmitted to 36, the power supply of the pump 36 is turned off, and the pump 36 holds the stopped state. The controller 16 transmits an opening command to the first electromagnetic valve 30 for humidified water, and the first electromagnetic valve 30 for humidified water opens the valve mechanism. Thirty minutes have passed since the first water pump 36 was operated, and either the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) is performed immediately after the pump 36 stops. .

  30 minutes have elapsed since the controller 16 performed the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) (30 minutes have elapsed since the first water pump 36 stopped). After that, the comparison between the measured odor level transmitted from the odor sensor 46 and the set odor level is resumed (measurement of the odor sensor 46 is substantially resumed). In the strong sterilization operation (strong sterilization operation) of FIG. 12, the controller 16 performs a first sterilization operation (first sterilization operation) in which the operation of the air conditioner 12 is stopped, as in FIG. However, a second sterilization operation (second sterilization operation) in which the operation of the air conditioner 12 is continued may be performed.

  The air conditioning system 10 </ b> C (air conditioning method) generates a bad odor from the humidifying element 22 or the drain pan 24 when bacteria are generated (propagated) in the humidifying element 22 or the drain pan 24, and the bad smell is measured by the odor sensor 46. 22 or the occurrence (reproduction) of bacteria in the drain pan 24 can be determined. In the air conditioning system 10C (air conditioning method), when the measured odor level exceeds the set odor level, generation of bacteria (reproduction) in the humidifying element 22 and the drain pan 24 is recognized, and the weak sterilization operation or the strong sterilization operation (sterilization operation) is performed. Therefore, even if bacteria are generated (bred) in the humidifying element 22 or the drain pan 24, the humidifying element 22 or the drain pan 24 can be reliably sterilized using the first functional water or the second functional water.

  Since the air conditioning system 10C (air conditioning method) can use the humidifying element 22 and the drain pan 24 in a clean state, the conditioned air is not mixed into the conditioned air from the humidifying element 22 or the drain pan 24 and is humidified. Clean air-conditioned air having an appropriate humidity or clean air-conditioned air having an appropriate humidity without being humidified can be supplied to the air-conditioning room 11.

  If the comparison between the odor level and the set odor level is continued during the sterilization operation (sterilization operation), the odor level may exceed the set odor level due to the odor of the functional water. However, the air conditioning system 10C (air conditioning method) stops the comparison between the odor level and the set odor level in the sterilization operation (sterilization operation), so the odor level is set by the odor of the functional water. The sterilization operation (sterilization operation) can be completed in an optimum time without exceeding the level.

  Moreover, when the comparison between the odor level and the set odor level is started immediately after the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) is performed, the odor level is determined by the odor remaining in the functional water. May exceed the set odor level, and unnecessary sterilization operation (sterilization operation) will be performed again. However, the air conditioning system 10C (air conditioning method) uses the first air conditioning operation (first air conditioning). Operation) or after the second air conditioning operation (second air conditioning operation) is performed, the comparison between the odor level and the set odor level is resumed 30 minutes later. It is not exceeded, and unnecessary sterilization operation (sterilization operation) can be prevented.

The odor sensors 46 </ b> A and 46 </ b> B measure the odor of the conditioned air flowing out from the blower 23 and transmit the measured odor to the controller 16. The odor sensors 46A and 46B are the same as those of the system 10C of FIG.

  The hard disk of the controller 16 stores the operating time of the first and second water pumps 36, 42, stores the set odor level (the set odor intensity), and the first air conditioning operation or the second. Stores the time from the start of air conditioning operation (after the pumps 36 and 42 are stopped) until the comparison between the measured odor level and the set odor level is resumed (measurement of the odor sensor 46 is substantially resumed). Has been. It is assumed that the operating time of the first and second water pumps 36 and 42 is set to 30 minutes. As for the constant odor level, 800 is set as the first set odor level, and 1200 is set as the second set odor level. It is assumed that 30 minutes is set as the time until the comparison between the measured odor level and the set odor level is resumed.

  The controller 16 compares the measured humidity transmitted from the humidity sensors 17A and 17B with the set humidity, and compares the measured odor level transmitted from the odor sensors 46A and 46B with the set first and second set odor levels. To do. The measured odor level is compared with the set odor level, and the measured humidity and the set humidity are compared. As a result, the measured odor level does not reach the set odor level, and the measured humidity does not reach the set humidity.

Thirty minutes have passed since the first water pump 36 was operated, and either the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) is performed immediately after the pump 36 stops. .

  30 minutes have elapsed since the controller 16 performed the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) (30 minutes have elapsed since the first water pump 36 stopped). After that, the comparison between the measured odor level transmitted from the odor sensor 46B and the set odor level is resumed (measurement of the odor sensor 46B is substantially resumed). In the strong sterilization operation (strong sterilization operation) of FIG. 16, the controller 16 performs a first sterilization operation (first sterilization operation) in which the operation of the air conditioner 12B is stopped, as in FIG. However, there is a case where the second sterilization operation (second sterilization operation) for continuing the operation of the air conditioner 12B is performed.

  In the air conditioning system 10D (air conditioning method), when bacteria are generated in each humidifying element 22 or each drain pan 24, odor is generated from the humidifying element 22 or drain pan 24, and the odor is measured by the odor sensors 46A and 46B. The occurrence (reproduction) of bacteria in the element 22 and the drain pan 24 can be determined. In the air conditioning system 10D (air conditioning method), when the measured odor level exceeds the set odor level, generation of bacteria (reproduction) in each humidifying element 22 and each drain pan 24 is recognized, and weak sterilization operation (weak sterilization operation) or strong Since the sterilization operation (strong sterilization operation) is carried out, even if bacteria are generated (propagated) in the humidifying element 22 or the drain pan 24, the humidifying element 22 or the drain pan 24 is surely secured using the first functional water or the second functional water. Can be sterilized.

  Since the air conditioning system 10D (air conditioning method) can use each humidifying element 22 and each drain pan 24 in a clean state, the air is not mixed from the humidifying element 22 or the drain pan 24 into the conditioned air. Thus, clean air-conditioned air having an appropriate humidity and clean air-conditioned air having an appropriate humidity without being humidified can be supplied to the air-conditioning rooms 11A and 11B.

  Since the air conditioning system 10D (air conditioning method) stops the comparison between the odor level and the set odor level in the sterilization operation (sterilization operation), the odor level does not exceed the set odor level due to the odor of the functional water, and the optimal time. The sterilization operation (sterilization operation) can be terminated. Since the comparison between the odor level and the set odor level is resumed 30 minutes after the first air-conditioning operation (first air-conditioning operation) or the second air-conditioning operation (second air-conditioning operation), the remaining odor of functional water Therefore, the odor level does not exceed the set odor level, and unnecessary sterilization operation (sterilization operation) can be prevented.

  Next, the case where the time schedule shown in FIG. 2 and the measured odor level measured by the odor sensors 46A and 46B are used together will be described based on the system 10D of FIG. As for the stop time (stop period) and the operation time (operation period) of the first and second water pumps 36 and 42, the same time (period) as that of the systems 10A and 10B of FIG. 1 and FIG. 6 is set. To do. Further, the time until the comparison between the measured odor level and the set odor level is resumed is set to the same time (period) as in the systems 10C and 10D of FIGS.

  In the air conditioning system 10D, the sterilization operation (sterilization operation) based on the odor level is given priority over the first and second air conditioning operations (first and second air conditioning operations) based on the time schedule. Accordingly, when the measured odor level exceeds the set odor level during the first and second air conditioning operations (during the first and second air conditioning operations), the sterilization operation (sterilization operation) is performed. In the air conditioning system 10D, the sterilization operation (sterilization operation) based on the time schedule can be prioritized over the sterilization operation (sterilization operation) based on the odor level. In this case, the sterilization operation (sterilization operation) according to the time schedule is not performed, and the sterilization operation (sterilization operation) based on the odor level is not performed. A second air conditioning operation (second air conditioning operation) and a sterilization operation (sterilization operation) are performed.

  If the measured humidity measured by each of the humidity sensors 17A and 17B has not reached the set humidity when the first and second water pumps 36 and 42 are at a stop time, the air conditioning system 10D (air conditioning method) The first air conditioning operation (first air conditioning operation) is performed according to the schedule. Since the first air conditioning operation (first air conditioning operation) is the same as that of the system 10B of FIG. 6, the description of the system 10B of FIG.

  When the measured humidity measured by each of the humidity sensors 17A and 17B has reached the set humidity when the first and second water pumps 36 and 42 are stopped, the air conditioning system 10D (air conditioning method) The second air conditioning operation (second air conditioning operation) is performed according to the schedule. Since the second air conditioning operation (second air conditioning operation) is the same as that of the system 10B of FIG. 6, the description of the system 10B of FIG.

  The controller 16 compares the measured odor levels transmitted from the odor sensors 46A and 46B with the set odor levels during the execution of the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation). To do. As a result of comparing the measured odor level and the set odor level, when the measured odor level has reached the first set odor level and the measured odor level has not reached the second set odor level, the first air conditioning operation (first 1 air conditioning operation) is stopped, and the weak sterilization operation (weak sterilization operation) by the second functional water supply line 15 is performed. It is assumed that the odor level measured by the odor sensor 46A reaches the first set odor level, and the odor level measured by the odor sensor 46B does not reach the first set odor level.

In the weak sterilization operation (weak sterilization operation), even if the measured odor is transmitted from the odor sensor 46A, the controller 16 does not compare the measured odor level with the set odor level. In the weak sterilization operation (weak sterilization operation), the supply of humidified water from the humidified water supply line 13 is stopped. The controller 16 continues the comparison between the measured odor level transmitted from the odor sensor 46B and the set odor level. In the weak sterilization operation (weak sterilization operation), the pump 42 is operated and the pump 36 is kept stopped. Further, the first switching electromagnetic valve 47A opens the valve mechanism, and the second switching electromagnetic valve 47B closes the valve mechanism.

  In the weak sterilization operation (weak sterilization operation), the second functional water is supplied to the entire area of the element 22 from the upper end portion 27 of the humidifying element 22 installed in the first air conditioner 12A, and the second functional water passes through the supply pipe 52. It is supplied to the drain pan 24. Since the valve mechanism of the second switching electromagnetic valve 47B is closed, the second functional water is not supplied to the humidifying element 22 and the drain pan 24 installed in the second air conditioner 12B. In the weak sterilization operation (weak sterilization operation), the humidifying element 22 of the first air conditioner 12A is sterilized with the second functional water, and the drain pan 24 is sterilized with the second functional water.

  When 30 minutes have elapsed since the operation of the second water supply pump 42 and the operation time of the second water supply pump 42 has elapsed, the power supply of the pump 42 is turned off, and the pump 42 maintains the stopped state. Further, the first electromagnetic valve 30 for humidified water opens the valve mechanism, and the electromagnetic valve 47A closes the valve mechanism. After 30 minutes have passed since the operation of the second water supply pump 42, immediately after the pump 42 stops, either the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) according to the time schedule. Is done. 30 minutes have elapsed since the controller 16 performed the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) (30 minutes have elapsed since the second water pump 42 was stopped). After that, the comparison between the measured odor level transmitted from the odor sensor 46A and the set odor level is resumed.

  The controller 16 compares the measured odor level with the set odor level during the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation). When the set odor level is reached, the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) is stopped, and the strong sterilization operation (strong sterilization operation) by the first functional water supply line 14 is performed. To implement. It is assumed that the odor level measured by the odor sensor 46B reaches the second set odor level, and the odor level measured by the odor sensor 46A does not reach the second set odor level.

In the strong sterilization operation (strong sterilization operation), even if the measured odor is transmitted from the odor sensor 46B, the controller 16 does not compare the measured odor level with the set odor level. In the strong sterilization operation (strong sterilization operation), the supply of humidified water from the humidified water supply line 13 is stopped. The controller 16 continues the comparison between the measured odor level transmitted from the odor sensor 46A and the set odor level. In the strong sterilization operation (strong sterilization operation), the pump 36 operates and the pump 42 holds the stopped state. Further, the second switching electromagnetic valve 47B opens the valve mechanism, and the first switching electromagnetic valve 47A closes the valve mechanism.

  In the strong sterilization operation (strong sterilization operation), the first functional water is supplied to the entire area of the element 22 from the upper end 27 of the humidifying element 22 installed in the second air conditioner 12B, and the first functional water passes through the supply pipe 52. It is supplied to the drain pan 24. Since the valve mechanism of the first switching electromagnetic valve 47A is closed, the first functional water is not supplied to the humidifying element 22 or the drain pan 24 installed in the first air conditioner 12A. In the strong sterilization operation (strong sterilization operation), the humidifying element 22 of the second air conditioner 12B is sterilized with the first functional water, and the drain pan 24 is sterilized with the first functional water.

  When 30 minutes have elapsed since the operation of the first water pump 36 and the operation time of the first water pump 36 has elapsed, the power supply of the pump 36 is turned off, and the pump 36 maintains the stopped state. Further, the first electromagnetic valve 30 for humidified water opens the valve mechanism, and the electromagnetic valve 47B closes the valve mechanism. 30 minutes have passed since the first water pump 36 was operated, and immediately after the pump 36 stopped, either the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) according to the time schedule. Is done. 30 minutes have elapsed since the controller 16 performed the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) (30 minutes have elapsed since the first water pump 36 stopped). After that, the comparison between the measured odor level transmitted from the odor sensor 46B and the set odor level is resumed.

  The air conditioning system 10D (air conditioning method) that uses both the time schedule and the measured odor level is performing the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) according to the time schedule. When bacteria are generated in each humidifying element 22 or each drain pan 24, odor is generated from the humidifying element 22 or drain pan 24, and the odor is measured by the odor sensors 46A and 46B, thereby generating bacteria in the humidifying element 22 and drain pan 24. (Breeding) can be determined. Accordingly, when the measured odor level exceeds the set odor level during the first air conditioning operation (first air conditioning operation) or the second air conditioning operation (second air conditioning operation) according to the time schedule, each humidifying element 22 or Bacteria generation (reproduction) was observed in each drain pan 24, and since weak sterilization operation (weak sterilization operation) or strong sterilization operation (strong sterilization operation) was performed, bacteria were generated (propagated) in the humidifying element 22 and the drain pan 24. Even so, the humidifying element 22 and the drain pan 24 can be reliably sterilized using the first functional water or the second functional water. In addition, since the weak sterilization operation (weak sterilization operation) or the strong sterilization operation (strong sterilization operation) is performed according to the time schedule, each humidifying element 22 and each drain pan 24 can be used in a clean state. In addition, bacteria and bad odors are not mixed into the air-conditioning air from the drain pan 24 or the drain pan 24, and clean air-conditioned air that has been humidified and has a proper humidity or clean air-conditioned air that has a proper humidity without being humidified is supplied to the air-conditioning rooms 11A and 11. Can be supplied.
