Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system for distributing indoor air between a plurality of indoor rooms.
[0002]
[Prior art]
As an air conditioning system that heats or cools a plurality of indoor rooms, for example, as disclosed in Japanese Patent Application Laid-Open No. 11-241849, a system in which an air conditioner is provided for each major room such as a Japanese-style room and a Western-style room is generally known. ing. In such a system, an air conditioner is operated in a room where a person is present to heat or cool the room.
[0003]
Further, as seen in, for example, Japanese Patent Application Laid-Open No. 5-172371, an integrated central air conditioning system including an air supply duct and an exhaust duct leading to each room is also known. In this system, heating and cooling of a room are performed by opening dampers provided at an air supply port and an exhaust port at a desired opening degree in a room where a person is present.
[0004]
However, in these systems, for example, when a person who is present in one room where heating is performed stops heating the room and moves to another room, the room of the source room is moved. Much of the heat energy in the warmed air is lost due to natural heat dissipation. In addition, if the destination room has not been heated before moving, the destination room will be heated independently from the cold state. It takes a lot of energy before it gets warm.
[0005]
Therefore, the conventional system has poor energy utilization efficiency.

[Problems to be solved by the invention]
This invention is made | formed in view of this background, and it aims at providing the air distribution system which can improve the utilization efficiency of the thermal energy of the air of an indoor room.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the indoor air circulation system of the present invention is provided such that indoor air can be moved between the plurality of rooms via an air flow passage that allows the indoor rooms to communicate with each other. Air moving means, air moving means provided so as to be able to move indoor air between a plurality of indoor rooms, and presence / absence determination means for determining presence / absence of a person in each of the plurality of rooms The room temperature detection means for detecting the room temperature of each of the plurality of rooms, and the determination result of the presence / absence determination means in the first room among the plurality of rooms is changed from occupancy to absence, When the determination result of the presence / absence determination means in the second room different from the first room changes from absence to presence, the first at the time of change from absence to presence in the second room. Detection room temperature in the first room and detection room temperature in the second room When the absolute value of the difference between the first room and the second room exceeds the predetermined value, the room air in the first room is changed to the second time until the absolute value of the difference between the detected room temperatures of the first and second rooms falls within the predetermined value. And control means for controlling the operation of the air moving means so as to be moved to the room.
[0009]
In the present invention, in a state where a person is present in any one room (first room) indoors, the room temperature of the room is generally determined by the operation of an air conditioner provided in the room, etc. It is a suitable temperature for the occupants (at least a temperature without any dissatisfaction). Then, when a person who is in the first room moves to another room (second room), the determination result of the absence determination means is that the first room is from the current room. It changes to absence and subsequently changes from absence to presence in the second room. At this time, the control means is such that the absolute value of the difference between the detected room temperature of the first room and the detected room temperature of the second room by the room temperature detecting means is a predetermined value (basically a value in the vicinity of 0, 0 It is judged whether it exceeds (including). If it exceeds, the control means controls the air moving means until the absolute value of the difference between the detected room temperature of the first room and the detected room temperature of the second room falls within the predetermined value. That is, the indoor air is circulated from the first room to the second room through the air flow passage until the detected room temperatures of both rooms become substantially equal.
[0010]
Here, in a situation where the absolute value of the difference between the detected room temperature of the first room from which the person moves and the detected room temperature of the second room at the destination exceeds a predetermined value, Since the room temperature is not a comfortable room temperature for the person, the person tries to make the room temperature of the second room suitable for himself / herself by operating an air conditioner provided in the second room. In this case, since room air having a suitable temperature in the first room as the movement source flows into the second room as the movement destination, a room temperature environment suitable for a person can be realized in the second room at an early stage. Even when the air conditioner is not provided in the second room, the room air in the first room flows into the second room, so that the room temperature of the second room is suitable for humans. And the comfort in the room temperature state of the second room can be enhanced.
[0011]
Therefore, according to the present invention, the thermal energy of the room air in the first room of the person's movement source is effectively utilized without vainly losing the room temperature comfort of the second room of the movement destination. Can be increased.
[0012]
In the present invention, the air flow passage may be constituted by a duct or the like. For example, when a plurality of rooms face a common hallway (passage), the hallway is used as an air flow passage. May be.
[0013]
When a ventilator for introducing outside air into the second room and an air conditioner for heating or cooling the second room are provided, the air conditioner is operated in the second room where the person is moving. After a certain amount of time has been carried out for some time (for example, after the room temperature of the second room has almost approached the set room temperature of the air conditioner), the ventilation apparatus is started automatically or manually to ventilate the room. There is a case. In this case, since the ventilator introduces outside air into the second room, the room temperature of the second room easily changes from a comfortable temperature to an outdoor temperature side. On the other hand, the room temperature of the first room of the movement source finally changes until it becomes equal to the outdoor temperature, but it tends to be a comfortable temperature side until it becomes substantially equal to the outdoor temperature.
[0014]
Therefore, in the present invention, when at least the second room is provided with a ventilator for introducing outside air and an air conditioner for heating or cooling the second room, the control means includes Means for obtaining operation information of the ventilation device and the air conditioner are provided. Then, the control means causes the air moving means to operate until the absolute value of the difference between the detected room temperatures of the first and second rooms falls within the predetermined value, and the second movement from the first room to the second room. After moving room air into the room, when grasping the parallel operation of the air conditioner and the ventilator, until the detected room temperature of the first room becomes substantially equal to the detected room temperature of the outdoor temperature detecting means, The air moving means is controlled to move room air from one room to a second room.
[0015]
According to this, the indoor air is moved from the first room to the second room by the air moving means until the absolute value of the difference between the detected room temperatures of the first and second rooms falls within the predetermined value. After that, when the air conditioner and the ventilator are operated in parallel, the air moving means causes the first room to be detected by the air moving means until the detected room temperatures of the first room and the second room are substantially equal. The room air in one room is moved to the second room. As a result, outside air is introduced into the second room at the destination by the ventilator, while indoor air having a temperature closer to a comfortable temperature from the first room is introduced into the second room. The operating load of the air conditioner in the room is reduced. That is, the energy consumption of the air conditioner in the second room can be reduced by utilizing the thermal energy of the room air in the first room.
[0016]

[0024]
A controller 22 that controls the system according to the present embodiment is provided at a suitable place in the house 1, for example, the western room 3. The controller 22 is an electronic circuit unit composed of a microcomputer or the like, and has functions as occupancy determination means and control means in the present invention. As shown in the block diagram of FIG. 2, the controller 22 includes the fan heaters 7 and 10, imaging devices 8 and 12, a ventilation fan device 13, in-room notification operation switches 15 and 16, room temperature sensors 19 a to 19 d, and an outside air temperature sensor. 19x and the air supply / exhaust devices 21a to 21d can communicate (transfer data) through a wired or wireless LAN (indicated by an arrow line in FIG. 2) or the like. The communication data will be described in more detail. For example, the operation information data of the fan heaters 7 and 10 and the ventilation fan device 13 (information such as whether the operation is being performed or stopped) is the fan heaters 7 and 10, respectively. And supplied to the controller 22 from the ventilation fan device 13. Also, video information data of the Japanese-style room 2 and the Western-style room 3 by the imaging devices 8 and 12 is given from the imaging devices 8 and 12 to the controller 22, and ON / OFF operation data of the occupancy notification operation switches 15 and 16 are these. To the controller 22 from the switches 15 and 16. Further, detected room temperature data from the respective room temperature sensors 19a to 19d is given from the room temperature sensors 19a to 19d to the controller 22, and detected temperature data from the outside air temperature sensor 19x is given to the controller 22 from the outside air temperature sensor 19x. And the controller 22 sends out the operation command which prescribes | regulates these driving | operation operation | movement to the air supply / exhaust apparatuses 21a-21d based on these given data, and controls the driving | operation of these air supply / exhaust apparatuses 21a-21d.
[0025]
As the room temperature sensors 19a and 19b of the Japanese-style room 2 and the Western-style room 3 respectively having the fan heaters 7 and 10, those provided in the fan heaters 7 and 10 may be substituted.
[0026]
Next, the operation of the system of the present embodiment will be described together with the detailed control processing of the controller 22. The controller 22 executes the processing shown in the flowchart of FIG. 3 to control the operation of the air supply / exhaust devices 21a to 21d.
[0027]
First, the controller 22 determines whether or not a person has moved from one room to another based on the video information data of the imaging devices 8 and 12 and the ON / OFF operation data of the occupancy notification operation switches 15 and 16. (STEP 1). More specifically, the controller 22 performs image processing on the video information data of the imaging devices 8 and 12 for the Japanese-style room 2 and the western-style room 3 by the function of the presence / absence determination unit, respectively, so that the rooms 2 and 3 To determine whether a person is present or absent. For example, it is determined that a person is present in the Japanese-style room 2 when a person is continuously photographed in the imaging device 8 in the Japanese-style room 2 for a predetermined time or more, and otherwise, the person is absent. To do.
[0028]
Further, the controller 22 uses the function of the presence / absence determination means for the undressing room 4 and the bath / toilet room 5 based on the ON / OFF operation data of the occupancy notification operation switches 15 and 16, respectively. 4 and 5 determine whether a person is present or absent. For example, when a person in the dressing room 4 turns on the occupancy notification operation switch 15 and the ON state continues for a predetermined time or more, it is determined that a person is in the dressing room 4 and Otherwise, it is determined that the person is absent.
[0029]
Then, the determination result of the presence / absence of a person in one room (the first room) changes from being in the room to being absent, and subsequently (specifically, within several tens of seconds), When the presence / absence determination result in one room (second room) changes from absence to presence, it is determined that a person has moved from the first room to the second room. . For example, when a person in the Japanese-style room 2 moves to the western-style room 3, it is determined by the video information data of the imaging device 8 in the Japanese-style room 2 that the Japanese-style room 2 has disappeared from the current room, and immediately after that, 3, it is determined that the Western-style room 3 has changed from being absent to the room (provided that there is no other person in the Western-style room 3 until that time). It is determined that there was a movement of a person from the Japanese-style room 2 to the Western-style room 3.
[0030]
In addition, the presence / absence of a person in the Japanese-style room 2 and the Western-style room 3 may be judged using an occupancy notification operation switch in the same manner as the undressing room 4 and the like. Further, the presence / absence of a person in the dressing room 4 and the bathroom / toilet room 5 may be determined using an imaging device, as in the case of the Japanese-style room 2 and the like. In the case of making a determination using the imaging device, the determination may be performed by the imaging device and the determination result may be output to the controller 22. Furthermore, the presence / absence determination in each room may be performed using an infrared sensor or the like.
[0031]
If it is determined in STEP 1 that a person has moved, the controller 22 next executes the control process in STEP 2 and subsequent steps by a function as a control means. In STEP2, the controller 22 acquires detected room temperature data of the movement source room (first room) and the movement destination room (second room) from the room temperature sensors of the respective rooms (STEP2). For example, when a person moves from the Japanese-style room 2 to the western-style room 3, the controller 22 acquires the detected room temperature data of the Japanese-style room 2 and the detected room temperature data of the western-style room 3 from the room temperature sensors 19a and 19b, respectively. In this embodiment, the processing after STEP 2 (including STEP 2) is not executed when the source room is the bath / toilet room 5.
[0032]
Next, the controller 22 determines whether or not the absolute value of the difference between the detected room temperature of the movement source room and the detected room temperature of the movement destination exceeds a predetermined value ε1 (for example, 1 ° C.) (STEP 3). If YES, the process from STEP2 is repeated through the process of STEP4. In STEP4, the controller 22 causes the air supply / exhaust device in the source room to perform a suction operation, and causes the air supply / exhaust device in the destination room to perform an air supply operation. As a result, the room air in the destination room is supplied to the destination room through the duct 20. For example, when the source and destination rooms are the Japanese-style room 2 and the Western-style room 3, respectively, the controller 22 causes the air supply / exhaust device 21a of the Japanese-style room 2 to perform a suction operation so that the indoor air in the Japanese-style room 2 is transferred into the duct 20 To suck. At the same time, the controller 22 performs the air supply operation of the air supply / exhaust device 21b of the western room 3 to supply the indoor air of the Japanese room 2 taken into the duct 20 by the air supply / exhaust device 21a of the Japanese room 2 to the western room 23. As a result, the indoor air in the Japanese-style room 2 moves to the western-style room 23.
[0033]
Here, for example, in winter, a person who is present in the Japanese-style room 2 usually performs the heating operation of the fan heater 7 in the Japanese-style room 2, and the room temperature of the Japanese-style room 2 is warmed to a comfortable room temperature for the person. It has been. When the person moves from the Japanese-style room 2 to the western-style room 3, if the room temperature of the Western-style room 3 is lower than the room temperature of the Japanese-style room 2 by more than the predetermined value ε1 (for example, 1 ° C.), as described above, Warmed room air in the Japanese room 2 is supplied to the Western room 3. For this reason, the western-style room 3 can be warmed to a room temperature side closer to a comfortable temperature for a person. A person who has moved to the Western-style room 3 usually starts the operation of the fan heater 10 or the floor heating device 11 in order to warm the room, but the warmed room air in the Japanese-style room 2 is positively applied to the Western-style room 3. By being supplied, the Western-style room 3 can be warmed up early. Therefore, it is possible to reduce the load on the fan heater 10 in the western room 3 while effectively utilizing the thermal energy of the room air in the Japanese-style room 2, and to reduce energy consumption.
[0034]
For example, when the destination room is the undressing room 4, although the undressing room 4 is not equipped with an air conditioner, the warmed indoor air of the Japanese-style room 2 as the source room is Since it is supplied to the undressing chamber 4 through the duct 20 and the air supply / exhaust device 21c, a person who has moved to the undressing chamber 4 works in a relatively warm environment until the air supply / exhaust device 21c stops as will be described later. It can be performed.
[0035]
In the routine processes in STEPs 2 to 4, until the determination result in STEP 3 is NO, that is, the absolute value of the difference between the detected room temperature in the source room and the detected room temperature in the destination room is equal to or less than the predetermined value ε1. Until they are at approximately the same temperature.
[0036]
When the determination result in STEP 3 is NO, the controller 22 stops the operation of the air supply / exhaust devices in the source and destination rooms (STEP 5). Note that the determination result of the first STEP 3 may be NO after the person has moved, but in STEP 5 in this case, the air supply / exhaust devices in the source and destination rooms are both stopped. Maintained.
[0037]
Next, the controller 22 determines whether there is air conditioning means and a ventilator in the destination room (STEP 6). Here, the data indicating whether or not each of the rooms 2 to 4 has air conditioning means and a ventilator is input in advance to the controller 22 and stored therein, and the determination in STEP 6 is performed based on the stored data. In the present embodiment, the room in which both the air conditioner and the ventilator are located is only the Western room 3 having the fan heater 10 as the air conditioner and the ventilator fan 13 as the ventilator.
[0038]
If the determination result in STEP 6 is NO, the controller 22 repeats the processes from STEP 1 without executing the processes after STEP 7 described below. If the determination result in STEP 6 is YES (in this embodiment, the destination room is the Western room 3), the controller 22 next uses the detected room temperature data of the source room as the room temperature of the room. While acquiring from a sensor, the detection temperature data of outside temperature are acquired from the outside temperature sensor 19x (STEP7).
[0039]
Next, the controller 22 determines whether or not the absolute value of the difference between the detected room temperature of the movement source room and the detected temperature of the outside air temperature exceeds a predetermined value ε2 (for example, 2 ° C.) (STEP 8). In this case, it is further determined whether or not both the air conditioner and the ventilator in the destination room are in operation (STEP 9). In the present embodiment, the determination process of STEP 9 is executed when the destination room is the Western room 3, and the determination of STEP 9 is based on the fan heater 10, the floor heating device 11, and the ventilation device 13 of the Western room 3. This is performed based on operation information data given to the controller 22.
[0040]
If the determination result of STEP 9 is NO, the process of the controller 22 returns to STEP 7, and if the determination result of STEP 9 is YES, the process from STEP 7 is repeated through the process of STEP 10. In STEP 10 described above, the controller 22 performs the suction operation of the air supply / exhaust device in the source room and the air supply operation of the air supply / exhaust device in the destination room. By the routine processing of STEPs 7 to 10, the operation of the fan heater 10 or the floor heating device 11 that is the air conditioner of the western room 3 as the destination room and the operation of the ventilation fan device 13 that is the ventilation device are performed in parallel. In this case, until the detected room temperature and the outside air temperature (detected temperature) of the movement source room are substantially equal, the room air of the movement source room passes through the duct 20 and the western room 3 (movement destination room). To be supplied.
[0041]
Here, when operating the ventilation fan device 3 of the Western-style room 3 as the destination room, the air in the Western-style room 3 is forcibly exhausted to the outside and the outside air is introduced into the Western-style room 3 through the vent hole 14. For this reason, the room temperature of the Western-style room 3 tends to change in a direction approaching the outside air temperature. Specifically, for example, in the winter season, when the western room 3 as a destination room is heated by the fan heater 10 or the floor heater 11 or both, the ventilation fan device 13 is used to ventilate the western room 3. When operated, the room temperature of the Western-style room 3 tends to decrease toward the outside temperature. In such a case, as long as the room temperature of the movement source room is higher than the predetermined value ε2 (for example, 2 ° C.) by the routine processing of STEPs 7 to 10, the movement source room Since the indoor air is supplied to the western room 3 (the destination room), the downward trend of the room temperature of the western room 3 is suppressed. And at this time, when performing a temperature control operation that keeps the room temperature in the western room 3 at a set temperature (a comfortable temperature for the occupant) by the fan heater 10 or the floor heating device 11 in the western room 3, As described above, the trend of lowering the room temperature of the western room 3 is suppressed, so that the energy consumption of the fan heater 10 and the floor heating device 11 can be suppressed.
[0042]
In the routine process of STEPs 7 to 10, until the determination result of STEP 8 is NO, that is, the absolute value of the difference between the detected room temperature of the movement source room and the detected temperature of the outside air temperature is equal to or less than the predetermined value ε2. It is performed until they are at approximately the same temperature.
[0043]
If the determination result in STEP 8 is YES, the controller 22 stops the operation of the air supply / exhaust devices in the movement source and movement destination rooms (STEP 11), and then returns to the processing in STEP 1. In STEP 11, when the operation of the air supply / exhaust devices in the source and destination rooms has already been stopped (when the first determination result in STEP 8 is YES), the operation stop state is maintained. Is done.
[0044]
FIG. 4 shows an example of a change in the room temperature of the movement source room and the room temperature of the movement destination room when the processing of the controller 22 described above is executed. In this example, the source room is, for example, the Japanese-style room 2, and the destination room is the Western-style room 3. In the Japanese room 2 of the source room, it is assumed that the temperature control operation of the fan heater 7 is performed when a person is present in the Japanese room 2.
[0045]
As shown in FIG. 4, when the controller 22 recognizes that a person has moved from the Japanese-style room 2 to the western-style room 3 at time t1, the movement of room air from the Japanese-style room 2 to the western-style room 3 starts, and the destination Western-style room As the room temperature T3 of No. 3 increases, the room temperature T2 of the source Japanese room 2 decreases. In this example, it is assumed that the heating operation (temperature control operation) of the western room 3 is started by the fan heater 10 or the floor heating device 11 immediately after the person moves to the destination western room 3.
[0046]
In this case, the room air warmed from the Japanese-style room 2 is supplied to the western-style room 3, so that the room temperature T3 of the western-style room 3 rises relatively quickly. Then, the room temperature T3 in the Western-style room 3 and the room-temperature T2 in the Japanese-style room 2 are substantially equal (specifically, | T3−T2 | ≦ ε1). Thereafter, the room temperature T2 of the moving Japanese-style room 2 is lowered by natural heat dissipation.
[0047]
After that, after the room temperature T3 of the western room 3 reaches a set temperature set by a person with the fan heater 10 or the like, it is assumed that the operation of the ventilation fan device 13 is started at time t3. At this time, the room temperature T2 of the source Japanese-style room 2 at time t3 is still higher than the outside temperature (specifically, T2> outside temperature + ε2).
[0048]
At this time, the movement of room air from the Japanese-style room 2 to the western-style room 3 is resumed, and the room air movement is such that the room temperature T2 of the Japanese-style room 2 is substantially equal to the outside air temperature (specifically, | T2−outside air temperature | ≦ ε2 It will be done until. In this case, outside air is introduced into the Western room 3 by the operation of the ventilation fan device 13 in the Western room 3, but the room air in the Japanese room 2 having a temperature higher than the outside air temperature is supplied to the Western room 3, so that the room temperature T3 of the Western room 3 is reached. Is suppressed from becoming a downward trend.
[0049]
In the embodiment described above, the example in which the Japanese-style room 2 and the Western-style room 3 are provided with a fan heater or a floor heating device as an air conditioner is shown. However, as an air conditioner in these rooms, an air conditioner capable of cooling and heating (normally A typical air conditioner device). In this case, even in the case where the Japanese-style room 2 or the Western-style room 3 is cooled in summer, the controller 22 performs the process of the flowchart of FIG. 3 to achieve the same effect as described in the embodiment. Can do. For example, when a person moves from the air-conditioned Japanese-style room 2 to the Western-style room 3, the dressing room 4, and the bath / toilet room 5, the difference between the room temperature of the Japanese-style room 2 and the room temperature of the destination room is large. When the absolute value of the difference exceeds the predetermined value ε1), immediately after the person moves, the cooled indoor air in the Japanese-style room 2 is supplied to the destination room, so that the destination room Can be cooled. In addition, for example, a person moves from the Japanese-style room 2 to the western-style room 3 and cools by the air conditioner of the western-style room 3, and then (after the movement of room air from the Japanese-style room 2 to the western-style room 3 is stopped), the ventilation of the western-style room 3 is performed. When the ventilation fan device 13 is operated to perform the operation, when the room temperature of the moving Japanese room 2 is still sufficiently lower than the outside air temperature (more specifically, the absolute value of the difference between the room temperature and the outside air temperature of the Japanese room 2 is the predetermined value). When the value ε2 is exceeded), the movement of room air from the Japanese-style room 2 to the western-style room 3 is resumed, so that the room temperature of the western-style room 3 can be suppressed from rising toward the outside temperature.

Moreover, in the said embodiment, although the example which moves indoor air between each room using the duct 20 was shown, for example, in a house where a plurality of rooms are arranged facing one hallway, The partition walls and doors between each room and the corridor are equipped with a blower that can move air in both directions (for example, a fan that can rotate in both forward and reverse directions). You may make it move room air via a hallway between. In this case, the air blower in the source room is operated to blow air from the room toward the hallway, and at the same time, the air blower in the destination room is operated to blow air from the hallway toward the room. Thus, the indoor air can be moved from the source room to the destination room.
