Description

TECHNICAL FIELD The present invention relates to an air conditioning system that performs control using information detected by a sensor installed in an air conditioning target space in which air conditioning equipment is installed.

Home appliances include home appliances that generate carbon monoxide (CO), such as kerosene stoves and gas water heaters. Carbon monoxide is one of the air quality that can adversely affect humans. Heat-not-burn cigarettes also emit a small amount of carbon monoxide. For this reason, inhabitants in enclosed spaces may suffer from carbon monoxide poisoning without realizing it. In addition, there are many cases where people inhale high concentrations of carbon monoxide while sleeping and develop symptoms. However, few homes are equipped with sensors for detecting the concentration of carbon monoxide, and accidents due to carbon monoxide poisoning continue to occur.

As for water heaters that are open to the room, such as small water heaters, since 1989, installation of an incomplete combustion prevention device has become obligatory for products manufactured by the Ordinance of the Ministry of Technology. However, even if the water heater is not incompletely combusted, the concentration of carbon monoxide in the air will increase if ventilation is insufficient. Therefore, it is essential to construct an environment or take countermeasures against carbon monoxide poisoning.

In recent years, the number of houses with high insulation performance and airtightness such as energy-saving houses is increasing. At present, 24-hour ventilation is obligatory in houses due to the revision of the Building Standards Law. However, the mandatory 24-hour ventilation does not apply to houses built in the past. For this reason, there are many houses with insufficient ventilation.

In addition, many air conditioners are not equipped with a ventilation function. Therefore, the room is ventilated by ventilation equipment such as a ventilation fan. In this case, if ventilation is performed alone without operating the air conditioning equipment, the room temperature cannot be maintained at a comfortable value, and when ventilation is finished, the room temperature may be far from the comfortable value. After that, when the air conditioner is operated, it takes a lot of time and energy to bring the indoor temperature to a comfortable value, and the efficiency of the air conditioner deteriorates. Therefore, in order to ventilate while maintaining the room temperature at a comfortable value, it is necessary to coordinately control air conditioning and ventilation.

Patent Document 1 includes a carbon monoxide concentration sensor and a room temperature sensor, and controls the ventilation device by determining whether to start or stop the ventilation device based on the measured values of both sensors, thereby keeping the room temperature constant. An indoor unit of an air conditioner capable of ventilating a room is disclosed.

JP-A-6-323606

However, according to the technique of Patent Document 1, since the carbon monoxide concentration sensor is provided in the indoor unit of the air conditioner, only the carbon monoxide concentration around the indoor unit can be measured, and the carbon monoxide concentration is generated. There is a problem that the carbon monoxide concentration cannot be detected in a place near the source where the carbon monoxide concentration is high. In this case, adequate ventilation may not occur.

The present invention has been made in view of the above, and provides an air conditioning system capable of cooperatively controlling air conditioning and ventilation according to the concentration of air quality in a space to be air conditioned. With the goal.

In order to solve the above-described problems and achieve the object, an air conditioning system according to the present invention includes an air conditioning facility installed in an air conditioning target space to perform air conditioning of the air conditioning target space, and an air conditioning system installed in the air conditioning facility. an individual sensor that is installed outside the air conditioning equipment in the air conditioning target space and detects the concentration of air quality in the air conditioning target space, a ventilation equipment that ventilates the air conditioning target space, and an air conditioning equipment and a system controller connected to the individual sensors and ventilation equipment via a communication network. The mounted sensors include a temperature sensor that detects the temperature of the air-conditioned space, a humidity sensor that detects the humidity of the air-conditioned space, and an infrared sensor that detects the surface temperature of the air-conditioned space. Based on the sensor data detected by the individual sensor, the system control unit calculates the future predicted value of the sensor data detected by the individual sensor, and whether or not to perform ventilation in the ventilation equipment based on the future predicted value is determined, and based on the sensor data detected by the mounted sensor and future predicted values, ventilation control in the ventilation equipment and the temperature and humidity of the air conditioning target space during ventilation in the ventilation equipment are determined in the air conditioning equipment It controls the coordinated operation linked with the air conditioning control in the air conditioning equipment that maintains the set temperature and humidity , and based on the sensor data sent from the infrared sensor, outside air enters the air conditioning target space from the outside. The place to come is specified, and the air conditioner is controlled so that the temperature and humidity of the place are returned to the current set temperature and set humidity of the air conditioner.

ADVANTAGE OF THE INVENTION The air conditioning system concerning this invention produces the effect that it is possible to coordinately control air conditioning and ventilation according to the state of the density|concentration of the air quality in the space for air conditioning.

It is a control unit that controls. The server control unit 53 can use not only the sensor data of the mounted sensors 13 mounted on the air conditioner 1 but also the sensor data of the individual sensors 2 connected to the same network as the air conditioner 1 .

Next, operation of the air conditioning system 100 will be described. FIG. 4 is a flow chart explaining the procedure of the operation at the start of control of the air-conditioning system 100 according to Embodiment 1 of the present invention.

First, at the start of the operation of the air conditioning system 100, in step S10, the server control unit 53 of the cloud server 5 checks the devices connected to the same communication network. That is, when starting the operation of the air conditioning system 100, the server control unit 53 confirms the devices of the air conditioning system 100 that can communicate with the cloud server 5 via the Internet 7 in the network of the air conditioning system 100. . Confirmation of the devices of the air conditioning system 100 that can communicate with the cloud server 5 is performed by a known method using a connection request or the like.

Next, in step S20, the mounted sensor 13 mounted on the air conditioning equipment 1 and various individual sensors 2 individually arranged separately from the air conditioning equipment 1 start collecting sensor data. The mounted sensor 13 and various individual sensors 2 detect the detection target at a predetermined cycle.

Next, in step S<b>30 , the mounted sensor 13 and various individual sensors 2 transmit sensor data, which are detection results, to the cloud server 5 via the wireless LAN router 4 and the Internet 7 . The server control unit 53 receives sensor data transmitted from the mounted sensor 13 and various individual sensors 2 via the server communication unit 51 . The server control unit 53 causes the server storage unit 52 to store the received sensor data.

Next, in step S40, the server control unit 53 activates the information analysis function of graphing the sensor data and calculating the predicted value of the target substance. FIG. 5 is a characteristic diagram showing an example of a graph created by the server control unit 53 of the cloud server 5 of the air conditioning system 100 according to Embodiment 1 of the present invention. In FIG. 5, the server control unit 53 shows a virtual graph in which data of carbon monoxide concentration in the air, which is sensor data detected by the carbon monoxide sensor 2f, is graphed.

A solid line in FIG. 5 is a curve connecting sensor data actually acquired by the server control unit 53 . The dashed line in FIG. 5 is the predicted value of the carbon monoxide concentration (%) in the air calculated by the server control unit 53 based on the actually acquired sensor data. The predicted value of the concentration of carbon monoxide in the air is the future predicted value of the target substance detected by the various individual sensors 2, calculated by the server control unit 53 based on the actually acquired sensor data. The server control unit 53 plots the sensor data actually acquired over a certain period of time on the virtual graph, and then extends the time axis and plots future predicted values of the target substance on the virtual graph.

In calculating the predicted value, for example, as shown in FIG. 5, a curve connecting values of actually acquired sensor data plotted on a virtual graph is created. Next, by making a tangent line to the curve, the constant slope of the tangent line is obtained. A tangent is made to the most recent sensor data portion of the curve. A value on the tangential line in the virtual graph becomes a predicted value corresponding to an arbitrary elapsed time from the present.

The server control unit 53 determines that the concentration of carbon monoxide in the air will reach the concentration threshold within the desired elapsed time when the calculated slope of the tangent line is greater than or equal to a predetermined slope threshold for the elapsed time. That is, in the virtual graph, time elapses with the slope of the tangent line of the latest sensor data portion on the curve, and it is determined whether the tangent line reaches the concentration threshold value within a predetermined elapsed time. Note that the method for calculating the predicted value is not limited.

Next, in step S50, the server control unit 53 determines whether or not the calculated predicted value of the target substance reaches a predetermined concentration threshold within a predetermined elapsed time as time elapses. The predetermined concentration threshold is a threshold for determining whether or not the server control unit 53 starts controlling the air conditioner 1 and the ventilation fan 3 . The density threshold is determined in advance and stored in the server storage unit 52 . The density threshold can be set to a desired value by transmitting information from the terminal 6 to the server storage unit 52 . The concentration threshold can be set individually for each of the various individual sensors 2 .

FIG. 6 is a diagram showing what percentage of carbon monoxide in the air affects humans. Although there are individual differences depending on age and sex, people generally develop symptoms as shown in FIG. 6 due to the influence of carbon monoxide concentration in the air. Carbon monoxide concentration in the air: 0.04% is the carbon monoxide concentration at which headache symptoms appear when a person breathes for one to two hours. Carbon monoxide concentration in the air: 0.08% is the carbon monoxide concentration that causes symptoms of headache, dizziness and nausea when a person breathes for 45 minutes. Carbon monoxide concentration in the air: 0.16% is the carbon monoxide concentration that causes symptoms of headache, dizziness and nausea when a person breathes for 20 minutes. Carbon monoxide concentration in the air: 0.32% is the carbon monoxide concentration at which a person will develop symptoms of headache and dizziness after breathing for 5 minutes, and will die after breathing for 26 minutes. Although there are individual differences depending on age and sex, the concentration threshold value is set to a numerical value of a well-known fact as shown in FIG. Note that the density threshold may be a value arbitrarily set by the user.

The server control unit 53 plots the actually obtained sensor data and the calculated future predicted value of the target substance on a virtual graph, and determines whether the predicted value when the time axis is extended reaches a predetermined concentration threshold value. determine whether That is, the server control unit 53 determines whether or not to start controlling the air conditioner 1 and the ventilation fan 3 depending on whether or not the predicted value reaches a predetermined concentration threshold.

If it is determined that the calculated predicted value of the target substance reaches the predetermined concentration threshold over time, the determination in step S50 is Yes, and the process proceeds to step S60. If it is determined that the calculated predicted value of the target substance does not reach the predetermined concentration threshold with the lapse of time, the determination in step S50 is No, and the process proceeds to step S100.

In step S60, the server control unit 53 controls the terminal 6 to display a message to the effect that "the calculated predicted value of the target substance reaches a predetermined concentration threshold over time" and the predicted value. For example, by allowing users to check the concentration of carbon monoxide each time, it is possible to realize a situation in which people can live safely in their homes.

Next, in step S70, the server control unit 53 performs control to start the ventilation operation of the ventilation fan 3 and control to maintain the set room temperature, thereby linking the air conditioning by the air conditioner 1 and the ventilation by the ventilation fan 3. Controls cooperative operation. That is, the server control unit 53 controls the ventilation fan 3 to start the ventilation operation. In addition, the server control unit 53 operates the air conditioner 1 so that the room temperature in the room to be air-conditioned is maintained at the set room temperature of the air conditioner 1 even after the ventilation operation of the ventilation fan 3 is started. control to allow As a result, it is possible to suppress and prevent discomfort to the user.

FIG. 7 is a diagram schematically showing control for maintaining the room temperature of the air conditioning target space at the set room temperature in the air conditioning equipment 1 even when the ventilation operation is started in the air conditioning system 100 according to Embodiment 1 of the present invention. be. In step S<b>70 , after the ventilation operation of the ventilation fan 3 is started, the server control unit 53 receives sensor data transmitted from the infrared sensor 13 c that is the mounted sensor 13 mounted on the air conditioner 1 .

Based on the sensor data transmitted from the infrared sensor 13c, the server control unit 53 identifies the location where outside air enters the room, which is the space to be air-conditioned, that is, the location where the ventilation fan 3 is installed. The server control unit 53 acquires information on the current set temperature of the air conditioner 1 from the air conditioner 1 . The server control unit 53 compares the current set temperature of the air conditioner 1 with the sensor data of the infrared sensor 13c, and installs the ventilation fan 3 in a place where the temperature is significantly different from the current set temperature of the air conditioner 1. identify the location where the

The server control unit 53, for example, selects a location that is higher than the current set temperature of the air conditioner 1 by a predetermined temperature range or more, or a location that is higher than the current set temperature of the air conditioner 1 by a predetermined temperature range or more. A low place can be specified as a place where the ventilation fan 3 is installed.

In addition, the server control unit 53 creates a temperature distribution in the room based on the sensor data transmitted from the infrared sensor 13c, and the temperature in the temperature distribution in the room varies by a predetermined temperature range or more compared to other areas. The place can also be specified as the place where the ventilation fan 3 is installed. In addition, the method of identifying the installation location of the ventilation fan 3 based on the sensor data transmitted from the infrared sensor 13c is not limited.

For example, as shown in FIG. 7, assume that the outdoor temperature is 5 degrees, the current set temperature of the air conditioner 1 is 24 degrees, and the current indoor temperature is 24 degrees. In this state, the ventilation fan 3 starts ventilation under the control of the server control unit 53 as described above. Ventilation by the ventilation fan 3 allows warm indoor air to flow outside. In addition, cold outside air enters the room due to ventilation by the ventilation fan 3 . The indoor temperature around the ventilation fan 3 becomes 10 degrees by the outside air taken into the room from the outside by the ventilation fan 3. - 特許庁Also, the indoor temperature is lowered.

The server control unit 53 controls the air conditioning equipment 1 so that the indoor temperature measured by the indoor temperature sensor 13 a of the air conditioning equipment 1 returns to the set temperature of the air conditioning equipment 1 . Here, the server control unit 53 identifies the place where the ventilation fan 3 is installed. Then, if the room temperature at the location where the ventilation fan 3 is installed is separated from the current set temperature of the air conditioner 1 by a predetermined temperature range or more, the server control unit 53 determines that the location where the ventilation fan 3 is installed The air conditioning equipment 1 is controlled so that the temperature of the air conditioning equipment 1 and its surrounding area is returned to the current set temperature of the air conditioning equipment 1 . An example of a predetermined temperature range is 2 degrees. The current set temperature of the air conditioner 1 is 24 degrees, the room temperature around the ventilation fan 3 is 10 degrees, and the predetermined temperature range is 2 degrees. The air conditioner 1 is controlled so as to pinpoint the temperature of the place where it is installed and the area around it to return to 24 degrees.

In addition, the server control unit 53 can similarly control indoor humidity. Such control by the server control unit 53 is preferably used in a hospital or the like, which is an environment where ventilation is required but the indoor temperature and indoor humidity should not be changed.

That is, as shown in steps S50 and S70, the server control unit 53 determines from the predicted value that the ventilation fan 3 and control of the air conditioner 1 is started. Then, the server control unit 53 performs control such as ventilation before the concentration of the air quality, which is affected by a person's continued presence in a space with a constant concentration, reaches the concentration threshold value from the normal value. For this reason, the server control unit 53 does not perform control after reaching the density threshold value, but uses the predicted value.

As described above, the air conditioning system 100 acquires information obtained from sensor data detected by various individual sensors 2 connected to the same communication network to the cloud server 5 , and processes the sensor data values. , to calculate the predicted value. Then, based on the predicted value and the predetermined concentration threshold value, it is determined whether or not ventilation is necessary, and if ventilation is necessary, control is performed to perform ventilation.

As a result, even if the room in which various individual sensors 2 are arranged is large, the air conditioning system 100 can arrange the individual sensors 2 in the room by arranging the individual sensors 2 at a location away from the air conditioning equipment 1. Ventilation can be performed appropriately according to the concentration of air quality in the area.

In addition, by using the infrared sensor 13c mounted on the air conditioning equipment 1, ventilation is performed to specify the place where the outside air is taken in, and control is performed to focus on the place where the outside air is taken in. By doing so, coordinated control of air conditioning and ventilation can be performed so that the indoor temperature and humidity are maintained at the set values of the air conditioner 1 even when ventilation is being performed.

That is, when outside air is taken into the room by ventilation, the environment of the indoor space, which has been kept comfortable, is disturbed by the ventilation due to the difference in temperature and humidity between the room and the outside. However, in the air conditioning system 100, since the infrared sensor 13c is installed in the air conditioning equipment 1, the state of indoor temperature, such as which part of the room is hot or cold, can be detected by the air conditioning equipment 1 and the server.

If there is information that cannot be acquired by the infrared sensor 13c and other sensors, the information can be input from the terminal 6 or the like to the server control unit 53 to improve the accuracy of cooperative control. Examples of information such as the size of the entire space include the height of the ceiling and the material of the walls.

In addition, the individual sensor 2 can be installed not only indoors but also outdoors, so that the space where the user spends can be comfortably managed together with the air flow during ventilation. If the sensor data is not improved even after ventilation, another countermeasure can be considered based on the sensor data of the individual sensors 2 installed indoors and outdoors that detect the same air quality.

Further, when the individual sensors 2 that detect the same air quality are installed both indoors and outdoors, the server control unit 53 can determine whether it is better to ventilate or not to ventilate. . That is, the server control unit 53 detects the sensor data detected by the internal individual sensor, which is the individual sensor 2 installed indoors, and the individual sensor installed outside the room that detects the same air quality concentration as the internal individual sensor.

On the other hand, the server control unit 53 does not perform ventilation in the ventilation equipment when the concentration of the air quality of the sensor data detected by the internal individual sensor is lower than the concentration of the air quality of the sensor data detected by the external individual sensor. Then, the prediction value is notified to the terminal 6 without causing the ventilation equipment to perform ventilation.

Further, the server control unit 53 can ventilate the room by the ventilation function of the air conditioner 1 after notifying the terminal 6 of the predicted value without ventilating the ventilation equipment as described above.

In addition, after notifying the terminal 6 of the predicted value without performing ventilation by the ventilation equipment as described above, the server control unit 53 detects the concentration of the air quality detected by the individual sensor 2 in the room. When connected to the same communication network, home appliances can be operated. Home appliances include, for example, air cleaners. This can improve the density of indoor air quality by means other than ventilation.

In addition, the server control unit 53, when the ventilation function of the air conditioning equipment 1 or home appliances connected to the communication network such as an air purifier are operating, the settings that are set in advance in the air conditioning equipment 1 The air conditioner 1 is controlled so as to maintain air conditioning conditions such as room temperature and set humidity. As a result, it is possible to suppress and prevent discomfort to the user.

The server control unit 53 also acquires information on the surface temperature of all areas in the room or a specified specific area detected by the infrared sensor 13c. Then, the server control unit 53 acquires the body temperature of a person or animal in the room from the information detected by the infrared sensor 13c, and detects an abnormality in the body temperature of the person or animal. The terminal 6 can be notified. If the body temperature of a person or animal is abnormal, for example, the obtained body temperature of a person or animal is outside a predetermined threshold temperature range.

Automobile exhaust contains a certain amount of carbon monoxide. For this reason, it is speculated that some people live without being aware of carbon monoxide poisoning. In addition to carbon monoxide, there are many substances in the air that become harmful depending on their concentration. The air conditioning system 100 can be applied as long as there is an individual sensor 2 that detects the air quality desired to be used for the above-described cooperative control, and the basic control is the same as described above.

By applying the air conditioning system 100 to a vehicle in which the air conditioning equipment 1 is installed, when the concentration of harmful substances in the air inside the vehicle is higher than the concentration of harmful substances in the air outside the vehicle, outside air is automatically taken in. It can be carried out. If the car engine is stopped for a long time, harmful substances discharged from the muffler may enter the car through the gaps in the trunk. In this case, the server control unit 53 compares the sensor data of the individual sensor 2 installed at a position where the air outside the vehicle is taken in from the air conditioner filter and the sensor data of the individual sensor 2 installed inside the vehicle. do. Then, when the air outside the vehicle has a lower concentration of harmful substances, the server control unit 53 automatically operates the air conditioner 1 to take in outside air. In addition, the server control unit 53 notifies the user of the dangerous state by, for example, sounding the horn.

By using the server control unit 53 of the cloud server 5 as a system control unit, the air conditioning system 100 can be constructed without significantly changing the hardware of the air conditioning control unit 14 of the air conditioning equipment 1 . Note that when the processing performance of the air conditioning control unit 14 of the air conditioning equipment 1 is high, the air conditioning control unit 14 of the air conditioning equipment 1 may be used as the system control unit without using the cloud server 5 .
