(Knowledge that became the basis of the present invention)
The present inventor has found that the following problems occur with respect to the ventilation system described in the “Background Art” section.

  In the ventilation system described in Patent Literature 1, when the ventilation load entering the room is large based on the outside air temperature and the room temperature, the first type ventilation for introducing the outside air into the total heat exchange element is performed, and the ventilation load When the size of is small, the third type ventilation is performed without introducing outside air into the total heat exchange element. Thus, in the ventilation system of patent document 1, when the magnitude | size of ventilation load is small, the electric energy consumed for ventilation ventilation is reduced by not introducing outside air into a total heat exchange element.

  However, the above ventilation system has a problem that the energy consumption for ventilation cannot be effectively reduced when the ventilation load is large. Specifically, when the ventilation system is arranged in a store having a kitchen room in the room, in such a store, the ventilator arranged in the kitchen room is operated to be different from the kitchen room in the store. Air flows from the area to the kitchen room. On the other hand, the area is supplied with air supply that is heat-exchanged with the exhaust air by a heat exchanger of a ventilator provided in the ventilation system.

  However, when the amount of air flowing into the kitchen room from the area increases, the air supplied by the ventilation system flows to the kitchen room. In addition to the increase in the amount of air flowing from the area into the kitchen room, in addition to the air supply from the ventilation system, the outside air is separated into the area from the gap between the walls, windows, doors, etc. Is aired. That is, by the operation of the ventilator in the kitchen room, outside air that has not been processed by the heat exchanger and has a large load on the air conditioning process flows. For this reason, even if it operates the ventilator which heat-exchanges exhaust gas and supply air with a heat exchanger, the said ventilator may not be able to reduce the heat load by supply air effectively. Therefore, in order to make the space in the area comfortable, the air in the area needs to be air-conditioned such as cooling and heating, and the air-conditioning equipment consumes a lot of energy for the air-conditioning processing.

  As described above, in the ventilation system described in Patent Document 1, the energy consumption of the air-conditioning equipment for the air-conditioning process cannot be effectively reduced.

  Therefore, a method of controlling an air supply device according to an aspect of the present disclosure is provided in a store area different from a kitchen room in a store, and performs heat exchange to exchange heat between the exhaust from the area and the air outside the store. When a ventilator equipped with a ventilator is operating, it increases the output of an air supply device provided in the kitchen room.

  For this reason, the energy consumption of the air-conditioning apparatus concerning the air-conditioning process in an area can be reduced effectively.

  In addition, when the parameter correlated with the temperature in the kitchen room is equal to or less than the first threshold, the output of the air supply is larger than the increase in the output of the air supply when the parameter is larger than the first threshold. The increase amount may be reduced.

  By the way, if the output of the air supply device provided in the kitchen room is increased, the amount of outside air flowing into the kitchen room increases. For this reason, when the outside air load is large, there is a problem that the comfort of the kitchen room is more easily impaired than when the outside air load is small.

  According to this, when the parameter correlated with the temperature in the kitchen room is equal to or lower than the first threshold, the increase in the output of the air supply device is larger than the increase in the output of the air supply device when the parameter is larger than the first threshold value. Reduce the amount. For this reason, when the comfort in the kitchen room is impaired or is likely to be impaired, the increase in the output of the air supply device is reduced, so that the comfort of the kitchen room can be reduced.

  In addition, when the parameter correlated with the temperature in the kitchen room is equal to or greater than the second threshold, the increase in the output of the air supply is greater than the increase in the output of the air supply when the parameter is less than the second threshold. The increase in output may be reduced.

  For this reason, since the amount of increase in the output of the air supply device is reduced when the comfort in the kitchen room is impaired or is likely to be impaired, it is possible to reduce the deterioration of the comfort of the kitchen room.

  Further, when there is a person in the kitchen room, the increase amount of the output of the air supply device may be smaller than the increase amount of the output of the air supply device when there is no person in the kitchen room.

  For this reason, it can reduce that the comfort in a kitchen room is impaired when there is a person in a kitchen room, and when the person is not in a kitchen room, the energy consumption concerning the air conditioner in an area can be reduced.

  Further, when the parameter correlated with the temperature in the kitchen room is equal to or less than a first threshold and there is a person in the kitchen room, the increase in the output of the air supply device when the parameter is greater than the first threshold. Alternatively, the increase in the output of the air supply device may be reduced.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  In addition, when the parameter correlated with the temperature in the kitchen room is equal to or less than a first threshold and there is a person in the kitchen room, the supply when the parameter is equal to or less than the first threshold and there is no person in the kitchen room. The increase amount of the air supply output may be made smaller than the increase amount of the air supply output.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  Further, when the parameter correlated with the temperature in the kitchen room is equal to or greater than a second threshold and there is a person in the kitchen room, the increase in the output of the air supply when the parameter is less than the second threshold The increase in the output of the air supply device may be made smaller.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  In addition, when the parameter correlated with the temperature in the kitchen room is equal to or greater than a second threshold and a person is present in the kitchen room, the supply is performed when the parameter is equal to or greater than the second threshold and no person is present in the kitchen chamber. The increase amount of the air supply output may be made smaller than the increase amount of the air supply output.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  Further, when the difference between the parameter correlated with the temperature in the kitchen room and the parameter correlated with the temperature outside the kitchen room is equal to or greater than a third threshold and there is a person in the kitchen room, the difference is more than the third threshold. You may make the increase amount of the output of the said air supply device smaller than the increase amount of the output of the said air supply device when it is small.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  Further, when the difference between the parameter correlated with the temperature in the kitchen room and the parameter correlated with the temperature outside the kitchen room is equal to or greater than a third threshold value and the person is in the kitchen chamber, the difference is equal to or greater than the third threshold value. And the increase amount of the output of the air supply device may be made smaller than the increase amount of the output of the air supply device when there is no person in the kitchen room.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  Further, when the parameter correlated with the temperature outside the kitchen room is equal to or lower than a fourth threshold value, the air supply is more than the amount of increase in the output of the air supply when the temperature outside the kitchen room is larger than the fourth threshold value. The increase in the output of the vessel may be reduced.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  In addition, when the parameter correlated with the temperature outside the kitchen room is equal to or higher than a fifth threshold, the supply amount is larger than the increase in the output of the air supply when the temperature outside the kitchen room is lower than the fifth threshold. The increase in the output of the air vessel may be reduced.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  Further, when the parameter correlated with the temperature outside the kitchen room is equal to or lower than a fourth threshold value and there is a person in the kitchen room, the increase in the output of the air supply device when the parameter is larger than the fourth threshold value. Alternatively, the increase in the output of the air supply device may be reduced.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  Further, when the parameter correlated with the temperature outside the kitchen room is equal to or greater than a fifth threshold and a person is present in the kitchen room, the supply when the parameter is equal to or greater than the fifth threshold and no person is present in the kitchen room. The increase amount of the air supply output may be made smaller than the increase amount of the air supply output.

  For this reason, the comfort in the kitchen room is impaired or is likely to be impaired, and if there is a person in the kitchen room, the increase in the output of the air supply device is reduced, and thus the comfort of the kitchen room is impaired. Can be reduced.

  These general or specific aspects may be realized by a system, a control device, an integrated circuit, a computer program, or a recording medium such as a computer-readable CD-ROM. The system, the control device, the integrated circuit, You may implement | achieve with arbitrary combinations of a computer program and a recording medium.

  Hereinafter, an air supply control method, an air supply control device, and a ventilation system according to an embodiment of the present invention will be specifically described with reference to the drawings.

  Note that each of the embodiments described below shows a specific example of the present invention. The numerical values, shapes, materials, constituent elements, arrangement positions and connection forms of the constituent elements, steps, order of steps, and the like shown in the following embodiments are merely examples, and are not intended to limit the present invention. In addition, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims indicating the highest concept are described as optional constituent elements.

(Embodiment 1)
[1. Constitution]
1 is an external perspective view showing an installation example of a ventilation system according to Embodiment 1. FIG. Specifically, FIG. 1A is an external view showing an installation example of an exhaust device 210 and an air supply device 220 provided in a kitchen room in a store. FIG. 1B is an external view showing an installation example of the ventilator 100, the ventilator 300, and the showcase 500 arranged in an area in the store. FIG. 2 is a plan view showing an example of installation of each component of the ventilation system and the showcase according to the first embodiment. FIG. 3 is a block diagram illustrating an example of a configuration of the ventilation system according to the first embodiment.

  Specifically, in FIG. 1 to FIG. 3, the ventilator 100, the exhaust device 210, the air supply device 220, the ventilator 300, the control device 400, the temperature detector 430, the human detector 440, the showcase 500, the door 600, A cooker 700 and an air conditioner 800 are shown. For example, the ventilation system 1 includes the ventilator 100, the air supply device 220, and the control device 400 among these components. The ventilation system 1 may further include at least one of the exhaust device 210 and the ventilator 300.

  The ventilation system 1 is a system for reducing energy consumption for air conditioning such as area air conditioning in a store. The store is, for example, a convenience store or a supermarket.

  As shown in FIGS. 1 and 2, the space in the store has a kitchen room and an area different from the kitchen room. The area is, for example, a store in the store. The kitchen room has a space that is continuous with the space in the area. Ventilator 100, ventilator 300, showcase 500, and air conditioner 800 are provided in the area. The exhaust device 210 and the air supply device 220 are provided in the kitchen room. The control device 400 may be provided in the area or may not be provided in the area.

  The ventilator 100 is provided in an area and includes a heat exchanger 110 that exchanges heat between exhaust from the area and air outside the store. The ventilator 100 has a first path through which supplied air passes and a second path through which exhausted air passes, and the air passing through the first path and the second path is heat. The exchanger 110 exchanges heat with each other. Specifically, the first route is a route in which outside air (OA) taken from outside the store such as outdoors passes through the heat exchanger 110 and is supplied from the air supply port 130 as air supply (SA) into the area. It is. The second route is a route in which the atmosphere (RA) taken from the atmosphere port 120 in the area passes through the heat exchanger 110 and is discharged as exhaust (EA) outside the store such as outdoors. The ventilator 100 is connected to each of an exhaust port outside the store, a suction port outside the store, an air inlet 120 in the area, and an air supply port 130 in the area by a duct.

  Moreover, the ventilator 100 is, for example, a first blower that blows air from outside to the area in the first route, and a second blower that blows air from inside the area to the outside in the second route. May be provided. The first blower and the second blower are each realized by, for example, a fan and a motor that rotates the fan.

  The ventilator 100 is, for example, a total heat exchanger.

  Here, the energy saving effect by the total heat exchanger will be described.

  FIG. 4 is a graph for explaining the relationship between the change in the outside air temperature and the presence or absence of the energy saving effect of the total heat exchanger. In FIG. 4, the vertical axis indicates the average power consumption per hour when the total heat exchanger is on and off when the air conditioner is heating indoors, and the horizontal axis is the outside air temperature. Indicates.

  As shown in FIG. 4, when the outside air temperature is 8 degrees or more and the total heat exchanger is on and when the total heat exchanger is off, the amount of power consumed for heating the air conditioner varies significantly. Absent. On the other hand, it can be seen that when the total heat exchanger is on at an outside air temperature of less than 8 ° C., the amount of power consumed for heating is significantly smaller than when the total heat exchanger is off. FIG. 4 illustrates a case where the air conditioner is heating in winter when the outside air temperature is less than 16 ° C., which is lower than 18-22 ° C., which is a comfortable room temperature, for example. Similarly, it can be said that the same can be said when the air-conditioning equipment is performing cooling in the summer when the outside air temperature is 30 ° C. or higher, for example, which is a comfortable indoor temperature of 24 to 28 ° C. In other words, when the total heat exchanger is on when the outside air temperature is equal to or higher than a predetermined temperature, it can be estimated that the amount of power consumed for cooling is significantly smaller than when the total heat exchanger is off.

  The ventilator 100 exchanges heat between the exhaust from the area and the supply air from outside the store. For this reason, if the difference between the air temperature in the store area and the air temperature outside the store is greater than a predetermined difference, the ventilator 100 maintains the air temperature in the store area by heat exchange. The effect can be increased. For this reason, the air-conditioning load of the area in a store can be reduced. Here, the air conditioning load is a heating load or a cooling load.

  The exhaust unit 210 is provided in the kitchen room and discharges the air in the kitchen room to the outside of the kitchen room. The exhaust unit 210 is connected to the kitchen room side of the exhaust duct connecting the outside of the kitchen room and the kitchen room, and exhausts the air in the kitchen room to the outside by blowing air in the kitchen room to the outside. The exhaust unit 210 exhausts the air in the kitchen room to the outside of the kitchen room at least when cooking is performed in the kitchen room. For this reason, the kitchen chamber is in a negative pressure state. In the present embodiment, the exhaust unit 210 may be controlled with a fixed air volume. Thereby, it is suppressed that air flows toward an area from a kitchen room, and it is reduced that the odor by cooking flows into an area. The exhaust device 210 is realized by, for example, a fan and a motor that rotates the fan.

  The air supply device 220 is provided in the kitchen room and supplies outside air into the kitchen room. The air supply device 220 is connected to an air supply duct that connects the outside and the kitchen room, and supplies the outside air into the kitchen room by blowing the outside air toward the kitchen room. The air supply device 220 can effectively ventilate the kitchen room together with the exhaust by the exhaust device 210 by supplying outside air into the kitchen room. Further, the air supply device 220 can control the pressure in the kitchen chamber by supplying air to the kitchen chamber. The air supply device 220 is realized by, for example, a fan and a motor that rotates the fan.

  In the present embodiment, air supply device 220 is controlled with a variable air volume in accordance with a control signal from control device 400. That is, when the air supply device 220 receives a control signal for increasing the output from the control device 400, the air supply device 220 increases the air volume by increasing the rotational speed of the motor. On the other hand, when the air supply device 220 receives a control signal for reducing the output from the control device 400, the air supply device 220 reduces the air volume by reducing the rotational speed of the motor.

  Further, the air supply device 220 is controlled with an air volume smaller than the air volume of the exhaust device 210 in order to maintain the kitchen chamber in a negative pressure state. That is, the air supply device 220 is controlled with a variable air volume in a range smaller than the air volume of the exhaust device 210.

  The ventilator 300 is provided in the area, and discharges the air in the area outside the area such as outdoors. Specifically, the ventilator 300 is connected to the area side of the exhaust duct that connects the outside of the area and the inside of the area, and blows the air in the area toward the outside, so that the air in the area is outside the area. To discharge. The ventilator 300 is realized by, for example, a fan and a motor that rotates the fan. The ventilator 300 may further supply air outside the area, such as outdoors, into the area.

  The control device 400 controls operations of the ventilator 100, the exhaust device 210, the air supply device 220, and the ventilator 300. Specifically, the control device 400 controls the operation of the air supply device 220 according to the operation of the ventilator 100. Control device 400 may control the operation of air conditioner 800. The control device 400 includes an acquisition unit 410 and a control unit 420.

  The acquisition unit 410 acquires information indicating that the ventilator 100 is operating. Further, the acquisition unit 410 may acquire information indicating that the device is operating from each of the exhaust unit 210, the air supply unit 220, and the ventilator 300. The information indicating that each device is operating includes information indicating an operation state such as an on / off state, a strong operation state, and a weak operation state of each device. The acquisition unit 410 may acquire the temperature in the kitchen room detected by the temperature detector 430. The acquisition unit 410 may acquire human detection information indicating whether or not there is a person in the kitchen room from the human detector 440.

  When the controller 420 acquires information indicating that the ventilator 100 is operating by the acquiring unit 410, the controller 420 increases the output of the air supply unit 220 provided in the kitchen room.

  The temperature detector 430 detects the temperature in the kitchen room. The temperature detector 430 is, for example, a temperature sensor.

  The human detector 440 detects whether or not there is a person in the kitchen room. The human detector 440 is, for example, a human sensor. Note that the human detector 440 may detect whether or not there is a person in the kitchen room based on whether the cooker 700 is on or off. That is, the person detector 440 may detect that there is a person in the kitchen room when the cooker 700 is on, and may detect that there is no person in the kitchen room when the cooker 700 is off.

  Here, the influence which the change of the inflow amount of the air which flows into the kitchen room from the area in the store has on the energy consumption applied to the air conditioner 800 such as air conditioner will be described.

  FIG. 5A is a graph showing the relationship between the outside air temperature and the average power consumption per hour for the air conditioner when the amount of air flowing from the area in the store into the kitchen room is large. FIG. 5B is a graph showing the relationship between the outside air temperature and the average power consumption per hour for the air conditioner when the amount of air flowing from the store area to the kitchen room is small.

  As shown in FIG. 5A, when the inflow amount is large, the average power consumption of the air conditioner 800 does not change so much when the ventilator 100 is on and when the ventilator 100 is off. This is because the amount of inflow of air from the area to the kitchen room increases, so that in addition to the air supply of the ventilation system 1 to the area, the gap between the wall, window, door, etc. This is probably because a lot of outside air is supplied.

  On the other hand, as shown in FIG. 5B, it can be seen that when the inflow amount is small, the average power consumption of the air conditioner 800 is smaller when the ventilator 100 is on than when the ventilator 100 is off. Thereby, it turns out that the effect which reduces the energy consumption concerning the air conditioner 800 in an area by the ventilator 100 when there is much inflow is smaller than when there is little inflow.

  Therefore, the controller 420 increases the output of the air supply device 220 when the ventilator 100 is operating. That is, the controller 420 decreases the inflow amount of air flowing from the area to the kitchen room by increasing the output of the air supply device 220 when the ventilator 100 is operating. Specifically, the controller 420 may reduce the output of the air supply device 220 by switching the air supply device 220 from on to off when the ventilator 100 is operating. Moreover, the controller 420 may increase the output of the air supply device 220 by switching the operation state of the air supply device 220 from the weak operation to the strong operation with a larger air flow rate than the weak operation.

  In addition, when the parameter correlated with the temperature in the kitchen room is equal to or less than the first threshold, the controller 420 supplies the air supply more than the increase amount of the output of the air supply device 220 when the parameter is larger than the first threshold. The increase amount of the output of the device 220 may be reduced. For example, the controller 420 reduces the output of the air supply device 220 when the temperature in the kitchen room is lower than the first threshold value in winter. Thereby, it can suppress that the temperature in a kitchen room falls further from a 1st threshold value.

  Specifically, the controller 420 turns on the air supply device 220 when the temperature in the kitchen room detected by the temperature detector 430 changes from a temperature higher than the first threshold value to a temperature lower than the first threshold value. The operation state of the air supply device 220 may be switched from the strong operation to the weak operation with a smaller air flow rate than the strong operation.

  On the other hand, when the temperature in the kitchen room detected by the temperature detector 430 changes from a temperature lower than the first threshold value to a temperature higher than the first threshold value, the controller 420 switches the air supply device 220 from OFF to ON. Alternatively, the operation state of the air supply device 220 may be switched from the weak operation to the strong operation with a larger air flow rate than the weak operation.

  In addition, when the parameter correlated with the temperature in the kitchen room is equal to or higher than the second threshold, the controller 420 supplies more than the amount of increase in the output of the air supply device 220 when the parameter is less than the second threshold. The amount of increase in the output of the vaporizer 220 may be reduced. For example, the controller 420 reduces the output of the air supply device 220 when the temperature in the kitchen room is higher than the second threshold in summer. Thereby, it can suppress that the temperature in a kitchen room rises further from a 2nd threshold value.

  Specifically, when the temperature in the kitchen chamber detected by the temperature detector 430 changes from a temperature lower than the second threshold value to a temperature higher than the second threshold value, the controller 420 turns the air supply device 220 on. It may be switched off, or the operating state of the air supply device 220 may be switched from the strong operation to the weak operation with a smaller air volume than the strong operation.

  On the other hand, the controller 420 switches the air supply device 220 from OFF to ON when the temperature in the kitchen room detected by the temperature detector 430 changes from a temperature equal to or higher than the second threshold value to a temperature lower than the second threshold value. Alternatively, the operation state of the air supply device 220 may be switched from the weak operation to the strong operation with a larger air flow rate than the weak operation.

  In addition, when there is a person in the kitchen room, the controller 420 may make the increase amount of the output of the air supply device 220 smaller than the increase amount of the output of the air supply apparatus 220 when there is no person in the kitchen room. .

  Specifically, the controller 420 changes the detection result by the human detector 440 from a state where it is detected that there is no person in the kitchen room to a state where it is detected that there is a person in the kitchen room. The air supply device 220 may be switched from on to off, or the operation state of the air supply device 220 may be switched from the strong operation to the weak operation with a smaller air flow rate than the strong operation.

  On the other hand, when the detection result by the human detector 440 changes from a state in which it is detected that there is a person in the kitchen room to a state in which it is detected that there is no person in the kitchen room, the controller 420 220 may be switched from off to on, or the operating state of the air supply device 220 may be switched from a weak operation to a strong operation with a larger air flow rate than the weak operation.

  Further, the controller 420 increases the output of the air supply device 220 when the parameter correlated with the temperature in the kitchen room is equal to or lower than the first threshold and the person is in the kitchen room when the parameter is larger than the first threshold.

The increase in the output of 220 is reduced. For example, the controller 420B reduces the output of the air supply device 220 when the temperature in the kitchen room becomes lower than the fourth threshold value in winter. Thereby, it can suppress that the temperature in a kitchen room falls near the 4th threshold value.

  Specifically, the controller 420B turns on the air supply device 220 when the temperature outside the kitchen room detected by the temperature detector 450 changes from a temperature higher than the fourth threshold value to a temperature lower than the fourth threshold value. The operation state of the air supply device 220 may be switched from the strong operation to the weak operation with a smaller air flow rate than the strong operation.

  On the other hand, when the temperature in the kitchen chamber detected by the temperature detector 450 changes from a temperature equal to or lower than the fourth threshold value to a temperature higher than the fourth threshold value, the controller 420B switches the air supply device 220 from off to on. Alternatively, the operation state of the air supply device 220 may be switched from the weak operation to the strong operation with a larger air flow rate than the weak operation.

  In addition, when the parameter correlated with the temperature outside the kitchen room is equal to or higher than the fifth threshold, the controller 420B is more than the amount of increase in the output of the air supply device 220 when the temperature outside the kitchen room is lower than the fifth threshold. The increase amount of the output of the air supply device 220 may be reduced. For example, the controller 420B reduces the output of the air supply device 220 when the temperature in the kitchen room becomes higher than the fifth threshold in summer. Thereby, it can suppress that the temperature in a kitchen room rises further from a 5th threshold value.

  Specifically, when the temperature outside the kitchen room detected by the temperature detector 450 changes from a temperature lower than the fifth threshold value to a temperature higher than the fifth threshold value, the controller 420 turns the air supply device 220 on. It may be switched off, or the operating state of the air supply device 220 may be switched from the strong operation to the weak operation with a smaller air volume than the strong operation.

  On the other hand, the controller 420 switches the air supply device 220 from OFF to ON when the temperature outside the kitchen room detected by the temperature detector 450 changes from a temperature equal to or higher than the fifth threshold value to a temperature lower than the fifth threshold value. Alternatively, the operation state of the air supply device 220 may be switched from the weak operation to the strong operation with a larger air flow rate than the weak operation.

  In addition, when the parameter correlated with the temperature outside the kitchen room is equal to or lower than the fourth threshold and there is a person in the kitchen, the controller 420B increases the output of the air supply device 220 when the parameter is larger than the fourth threshold. The increase amount of the output of the air supply device 220 may be made smaller than the amount.

  Specifically, the controller 420B changes the temperature outside the kitchen room detected by the temperature detector 450 from a temperature higher than the fourth threshold value to a temperature equal to or lower than the fourth threshold value, and the human detector 440. When the detection result by the state changes from a state where it is detected that there is no person in the kitchen room to a state where it is detected that there is a person in the kitchen room, the air supply device 220 may be switched from on to off. The operation state of the air supply device 220 may be switched from the strong operation to the weak operation with a smaller air flow rate than the strong operation.

  On the other hand, when the temperature outside the kitchen room detected by the temperature detector 450 changes from a temperature equal to or lower than the fourth threshold value to a temperature higher than the fourth threshold value, the controller 420B switches the air supply device 220 from off to on. Alternatively, the operation state of the air supply device 220 may be switched from the weak operation to the strong operation with a larger air flow rate than the weak operation.

  In addition, when the parameter correlated with the temperature outside the kitchen room is equal to or greater than the fifth threshold and there is a person in the kitchen room, the controller 420B supplies the parameter when the parameter is equal to or greater than the fifth threshold and there is no person in the kitchen room. The increase amount of the output of the air supply device 220 may be made smaller than the increase amount of the output of the air device 220.

  Specifically, the controller 420B changes the temperature outside the kitchen room detected by the temperature detector 450 from a temperature lower than the fifth threshold value to a temperature equal to or higher than the fifth threshold value, and by the human detector 440. When the detection result changes from a state where it is detected that there is no person in the kitchen room to a state where it is detected that there is a person in the kitchen room, the air supply device 220 may be switched from on to off, You may switch the driving | running state of the air supply device 220 from a strong driving | operation to the weak driving | operation of the ventilation volume less than a strong driving | operation.

  On the other hand, when the temperature outside the kitchen room detected by the temperature detector 450 changes from a temperature equal to or higher than the fifth threshold value to a temperature lower than the fifth threshold value, the controller 420B switches the air supply device 220 from off to on. Alternatively, the operation state of the air supply device 220 may be switched from the weak operation to the strong operation with a larger air flow rate than the weak operation.
