  The present invention relates to a ventilation system, and more particularly to a ventilation system that discharges chemical substances in the air generated from building materials and furniture to the outside of the room.

  In recent years, with the advancement of airtightness of buildings in order to improve the efficiency of air conditioning, the contamination of indoor air by volatile chemical substances generated from building materials and furniture has become a problem. Inhalation of air contaminated with volatile chemicals may adversely affect human health, so ventilating the interior of the room vents the volatile chemicals to the outside. A system has been proposed (see, for example, Patent Document 1). In this indoor ventilation system, in order to reduce power consumption, the ventilation amount of the ventilation fan device is decreased as the elapsed time from the start of the operation of the ventilation fan device increases. Moreover, since it is thought that more organic compounds volatilize and are ventilated, so that the average value of the past room temperature is high, in the indoor ventilation system of patent document 1, as the average value of the past room temperature is high, The ventilation volume of the ventilation fan is reduced.

  In the indoor ventilation system of Patent Document 1 described above, the power consumption is reduced by decreasing the ventilation amount of the ventilation fan device as the elapsed time from the start of operation increases, but the ventilation fan device continues to move. Therefore, there is a problem that a lot of power is consumed after all. Further, in the indoor ventilation system of Patent Document 1, since the organic compound that volatilizes at normal temperature is ventilated, the organic compound may volatilize over a long period of time, and the indoor ventilation system needs to be operated for a long period of time.

The said control apparatus is comprised so that the operation | movement of the said air conditioning apparatus may be controlled and the heating control which raises room temperature to more than predetermined 1st temperature higher than the preset temperature range at the time of air conditioning is performed. In the state in which the control device is performing the heating control, a predetermined second temperature that is higher than the set temperature range and lower than the first temperature exceeds the room temperature measured by the measurement device. When the integrated value becomes equal to or greater than a predetermined threshold value, the heating control is terminated and ventilation control is performed to operate the intake part and the exhaust part, respectively.

  The ventilation system may include an outside air temperature acquisition unit that acquires the outdoor air temperature outside the room. If the outside air temperature acquired by the outside air temperature acquisition unit is equal to or higher than the first temperature, the control device performs the heating control by operating the air intake unit without operating the air conditioner. Composed.

  The ventilation system may include an outside air temperature acquisition unit that acquires the outdoor air temperature outside the room.

  Various volatile chemical substances are used for building materials used in building rooms and furniture used in rooms, such as adhesives, paint solvents, and preservatives. Volatile chemical substances contained in building materials and fixtures are easy to volatilize even at room temperature, and these chemical substances exist as gases in the indoor air, so if people inhale air contaminated with chemical substances, May harm your health. The ventilation system of this embodiment is used to ventilate air in an indoor space contaminated with volatile chemicals and reduce volatile chemicals present in the indoor air. The WHO (World Health Organization) classifies organic indoor air pollutants by boiling point. Among organic indoor air pollutants, chemical substances having a boiling point of 50 ° C. to 260 ° C. (for example, toluene, xylene, ethylbenzene, etc.) are classified as volatile organic compounds (VOC). Further, among organic indoor air pollutant chemical substances, chemical substances (for example, formaldehyde and acetaldehyde) having a boiling point lower than that of VOC are classified as very volatile organic compounds (VVOC). Hereinafter, volatile organic compounds and supervolatile organic compounds are collectively referred to as volatile chemical substances.

  FIG. 1 is a schematic system configuration diagram of the ventilation system of the present embodiment. The ventilation system includes a ventilation device 1, a temperature sensor 2 as a measurement device, an air conditioner 3, and a control device 4. Moreover, the ventilation system of this embodiment is provided with the operation terminal 5 provided with the operation function and the display function in addition to said structure.

  The ventilation device 1 is for ventilating an indoor space 100 surrounded by a wall, and includes an intake unit 11 and an exhaust unit 12. The intake section 11 is a blower for taking outside air into the indoor space 100 from the outside. The exhaust unit 12 is a blower for exhausting the air in the indoor space 100 to the outside.

  The temperature sensor 2 measures the room temperature of the indoor space 100 with a temperature sensing element such as a thermistor, and outputs the measured room temperature data to the control device 4.

  The air conditioner 3 includes an air conditioner that cools and heats the indoor space 100, for example, and adjusts the air environment of the indoor space 100 to a temperature or humidity condition set by a user using a setting device (not shown).

  The control device 4 controls the operations of the ventilation device 1 and the air conditioning device 3, respectively. The control device 4 has a communication function for connecting to a wide area communication network 110 such as the Internet, and is configured to perform data communication with the server 120 via the wide area communication network 110.

  The operation terminal 5 is a user interface including a liquid crystal display for displaying characters and images and an input device such as a touch panel. The operation terminal 5 includes, for example, a display device with a touch panel prepared exclusively for the ventilation system, a general-purpose tablet terminal, a mobile phone, and a smartphone. The operation terminal 5 displays display data input from the control device 4 and outputs data input by the user to the control device 4.

  This ventilation system warms the indoor space 100 to promote volatilization of volatile chemical substances and discharges the volatilized chemical substances to the outside of the room (this operation is hereinafter referred to as air purification operation). The description will be given with reference. FIG. 2 is a flowchart of the air purification operation. FIG. 3 is a time chart showing the operations of the air conditioner 3 and the ventilator 1. FIG. 4 is a diagram illustrating a temperature change at room temperature when the control device 4 performs the heating control.

  For example, when a resident performs an operation for starting an air purification operation using the operation terminal 5, a signal for starting the air purification operation is transmitted from the operation terminal 5 to the control device 4, and the control device 4 starts the air purification operation. Note that the time zone for performing the air purification operation is preset in the control device 4, and the control device 4 may start the air purification control when the time zone is set every day or every several days. .

  When the air purification control is started, the control device 4 acquires, for example, the outside air temperature TO1 measured by the temperature sensor for detecting the outside air temperature provided in the outdoor unit (not shown) from the air conditioner 3 (step S1 in FIG. 2). . Here, the control device 4 has a function of an outdoor temperature acquisition unit that acquires outdoor outdoor temperature.

The control device 4 stores a third temperature T3 used when determining whether or not to perform the air purification process in a memory (not shown), and sets the third temperature T3 read from the memory (step S2). ). The third temperature T3 is an outside air temperature at which the energy required to warm the indoor space 100 to a temperature at which the volatile chemical substance is likely to volatilize (first temperature T1 described later) becomes excessive. It is set to ℃.
The control device 4 compares the outside temperature TO1 acquired from the air conditioner 3 in step S1 with the level of the third temperature T3 set in step S2 (step S3).

  When the outside air temperature TO1 is higher than the third temperature T3 (Yes in Step S3), the control device 4 compares the levels of the outside air temperature TO1 and the first temperature T1 (Step S4), and purifies the air according to the comparison result. The control mode of control is switched to either the first mode or the second mode. The first temperature T1 is higher than a set temperature range W1 (for example, 16 ° C. or higher and 30 ° C. or lower) of the air conditioner 3 set at the time of air conditioning, and is an upper limit temperature that can be adjusted by the heating capacity of the air conditioner 3 (For example, 32 ° C.). The first temperature T1 may be set to a temperature that is higher than the upper limit value of the set temperature range W1 of the air conditioner 3 by a certain temperature, or may be set to any temperature that is higher than the set temperature range W1.

  As a result of the determination in step S4, if the outside air temperature TO1 is lower than the first temperature T1 (No in step S4), the control device 4 performs air purification control in the first mode (step S5). On the other hand, if the outside air temperature TO1 is equal to or higher than the first temperature T1 (Yes in Step S4), the control device 4 performs the air purification process in the second mode (Step S6). In the air purification control of the first mode, the air in the indoor space 100 is warmed by the air conditioner 3 to promote volatilization of the volatile chemical substance, and then the air in the indoor space 100 is exhausted. In the air purification control in the second mode, the indoor space 100 is warmed by taking outside air having a temperature equal to or higher than the first temperature T1 into the indoor space 100 to promote volatilization of volatile chemical substances, and then the air in the indoor space 100 is exhausted. .

  Here, the case where the control device 4 performs the air purification control in the first mode will be described with reference to FIGS. 3 and 4. Assuming that the air purification control is started at time t1 in FIGS. 3 and 4, in the air purification control in the first mode, the control device 4 controls the operation of the air conditioner 3 while the ventilation device 1 is stopped. Thus, heating control is performed to raise the room temperature to a predetermined first temperature T1 or higher that is higher than the set temperature range during cooling and heating. Further, the control device 4 outputs, for example, a control command for displaying a warning message “The current temperature is a temperature environment in which VOCs are easily volatilized” to the operation terminal 5, and the operation terminal 5 controls the control device 5. A warning message is displayed on the liquid crystal display based on the control command from 4. By displaying a warning message on the liquid crystal display of the operation terminal 5, it is possible to prompt a person in the indoor space 100 to go out of the indoor space 100, and the person in the indoor space 100 is contaminated with a volatile chemical substance. You can avoid inhaling air.

  When the control device 4 performs the heating control by controlling the operation of the air conditioner 3, the room temperature of the indoor space 100 gradually increases as shown in FIG. 4, and eventually becomes stable at the first temperature T1. When the room temperature is adjusted to a temperature higher than the temperature set at the time of air conditioning by the air conditioner 3, compared with the case where the temperature is adjusted to the normal set temperature range W1, volatile chemicals contained in building materials and furniture Substances are likely to volatilize. Therefore, while the control device 4 performs heating control and the room temperature is adjusted to a temperature higher than that during normal cooling and heating, the volatilization of volatile chemical substances contained in the building material or furniture of the indoor space 100 may occur. There is a chemical substance that is promoted and volatilized in the air of the indoor space 100.

  In the state in which the control device 4 is performing the heating control, the integrated value corresponding to the room temperature exceeding the predetermined second temperature T2 lower than the first temperature T1 (hatched portion A1 in FIG. 4) is equal to or greater than the predetermined threshold At time t <b> 2 when, the control device 4 ends the heating control and stops the air conditioner 3. After stopping the air conditioner 3, the control device 4 operates the intake unit 11 and the exhaust unit 12 of the ventilator 1, taking outside air into the indoor space 100 from the outside, and bringing the air in the indoor space 100 to the outside. Discharge and volatilize chemical substances outside the room. When the air conditioner 3 is stopped and the indoor space 100 is ventilated, the room temperature of the indoor space 100 gradually decreases, so that volatile chemical substances contained in building materials, furniture, and the like are less likely to volatilize. The control device 4 stops the operation of the ventilation device 1 at time t3 when a predetermined time (for example, 30 minutes) has elapsed from time t2, and performs heating control again.

  That is, when the time t3 comes, the control device 4 controls the operation of the air conditioner 3 to perform the heating control for raising the room temperature to the first temperature T1 or higher. During this period, the control device 4 applies the building material, furniture, etc. of the indoor space 100 Volatile chemical substances are volatilized. Thereafter, at the time t4 when the integrated value of the room temperature exceeding the second temperature T2 becomes equal to or greater than a predetermined threshold in the state where the heating control is performed, the control device 4 ends the heating control, and the air conditioning device 3 is stopped. After stopping the air conditioner 3, the control device 4 operates the intake unit 11 and the exhaust unit 12 of the ventilator 1, taking outside air into the indoor space 100 from the outside, and bringing the air in the indoor space 100 to the outside. Discharge and volatilize chemical substances outside the room. The control device 4 stops the ventilation device 1 at time t5 when a predetermined time (for example, 30 minutes) has elapsed since the ventilation device 1 was operated.

  As described above, in the air purification control in the first mode, the control device 4 controls the operation of the air conditioner 3 to perform the heating control to warm the room temperature to the first temperature T1 and volatilize the volatile chemical substance. The operation of ventilating the air in the indoor space 100 by the ventilation device 1 is repeated twice. As a result, the total amount of volatile chemical substances remaining in the building materials and fixtures in the indoor space 100 is reduced, and thereafter the amount of volatile chemical substances volatilized from the building materials and fixtures is suppressed, and the air in the indoor space is reduced. Contamination can be reduced. In this embodiment, in the air purification control in the first mode, the control device 4 repeats the control routine for performing the ventilation control after performing the heating control twice, but the ventilation control is performed after performing the heating control. You may repeat the control routine which performs 3 times or more.

  Next, air purification control in the second mode will be described. In the air purification control in the second mode, the control device 4 operates the ventilator 1 with the air conditioner 3 stopped, and the outside air is taken into the indoor space 100 from the outdoor portion by the air intake portion 11 and the indoor portion 100 is taken in by the exhaust portion 12. The air in the space 100 is exhausted to the outside. Further, the control device 4 outputs, for example, a control command for displaying a warning message “The current temperature is in a temperature environment in which VOC is likely to volatilize” to the operation terminal 5, and the operation terminal 5 performs control. A warning message is displayed on the liquid crystal display based on a control command from the device 4. When a predetermined time (for example, 3 hours) has elapsed since the start of air purification control in the second mode, the control device 4 stops the ventilation device 1 and ends the air purification control in the second mode.

  As described above, if the outside air temperature is equal to or higher than the first temperature T1, the control device 4 does not operate the air conditioner 3 and warms the indoor space 100 by taking in outside air. It is possible to reduce the power required to do this.

  If the outside air temperature TO1 is equal to or lower than the third temperature T3 in the determination in step S3 (No in step S3), the control device 4 stops the air purification control (step S7) and ends the operation. . When the outside air temperature TO1 is equal to or lower than the third temperature T3, the power consumed by the air conditioner 3 is excessive to warm the room temperature to the first temperature T1 or higher. Further, if the outside air temperature TO1 is equal to or lower than the third temperature T3, the room temperature is also low, and it is expected that the volatile chemical substance is less likely to volatilize from building materials or furniture. Therefore, when the outside air temperature TO1 is equal to or lower than the third temperature T3, the control device 4 stops the air purification control, whereby the power consumption by the ventilation system can be reduced.

  Here, the control device 4 may use a preset temperature as the third temperature T3, or may calculate it from past weather data of an area where the building is located. It is assumed that past meteorological observation data of each place is accumulated in the server 120. The control device 4 accesses the server 120 via the wide area communication network 110, and acquires the temperature data (the highest temperature and the lowest temperature for each day) of the same month in the area where the building is located from the server 120 over the past several years. The control device 4 extracts the maximum temperature and the minimum temperature for a certain period including the current day from the past temperature data acquired from the server 120, and calculates the average maximum temperature Ta1 and the average minimum temperature Ta2 for this certain period. And the control apparatus 4 calculates 3rd temperature T3 by the following formula | equation (1) using the average maximum temperature Ta1 and average minimum temperature Ta2 in a fixed period, and arbitrary coefficients c.

T3 = Ta2 + (Ta1-Ta2) × c (1)
For example, the current day is September 1, and the average maximum temperature Ta1 for the past several years is 26.4 ° C. and the average minimum temperature Ta2 is 17.2 for a certain period from September 1 to September 5, for example. If the coefficient c is 0.4, the third temperature T3 is calculated to be about 20.9 ° C. In this way, if the control device 4 sets the third temperature T3 by performing the above calculation based on the past weather observation data in the area where the building is located, it is determined whether or not to perform the air purification process. Therefore, the third temperature T3 can be set according to the climatic conditions of each region. If the coefficient c is set to a larger value, the third temperature T3 is set higher, so that the power consumption required when the air conditioner 3 performs the heating control is reduced. Further, even if the control device 4 acquires weather forecast information (for example, predicted temperature for each hour) from the server 120 and sets the third temperature T3 by calculation using the predicted maximum temperature, the predicted minimum temperature, and the coefficient c. Good.

  By the way, when the air purification control in the first mode is being executed and the outside air temperature TO1 falls below the third temperature T3 during the ventilation by the ventilation device 1, the control device 4 causes the ventilation device 1 to have a predetermined set time. The air purification control may be stopped after the ventilation operation is performed. Since the control device 4 continues the ventilation operation of the ventilator 1, the chemical substance volatilized by the air conditioner 3 performing the heating control can be discharged to the outside.

  In addition, when the air purification control in the first mode is being executed and the outside air temperature TO1 is lowered to the third temperature T3 or lower during the heating control by the air conditioner 3, the control device 4 Stop control immediately. And the control apparatus 4 should just stop air purification control, after making the ventilator 1 perform ventilation operation only for the predetermined setting time. Since the control device 4 immediately stops the heating control by the air conditioner 3 and then causes the ventilator 1 to perform the ventilation operation for a predetermined set time, the control device 4 volatilizes when the air conditioner 3 performs the heating control. The discharged chemical substances can be discharged outside the room.

  Moreover, in the ventilation system of this embodiment, as shown in FIG. 5, the human detection part 6 which detects whether a person exists in the indoor space 100 is provided, and the human detection part 6 has detected the presence of a person. In the meantime, it is also preferable that the control device 4 does not perform the heating control.

  The human detection unit 6 includes a pyroelectric infrared sensing element that senses heat rays emitted from the human body. The human detection unit 6 detects whether or not a person is present in the indoor space 100 using the infrared sensing element, and outputs the detection result to the control device 4. In addition, the person detection part 6 is not limited to what uses an infrared sensing element. For example, the human detection unit 6 uses an image sensor that captures the entrance and exit to the indoor space 100, detects the entrance and exit of the person by performing image processing on the image captured by the image sensor, and based on the result, the presence or absence of the person in the indoor space 100 is detected. It may be detected. In addition, the person detection unit 6 detects the presence / absence of a person in the indoor space 100 based on information that detects the person's entry and exit from a security system (not shown) that manages entering and leaving the indoor space 100. May be.

  The control device 4 does not perform the heating control when performing the air purification control in the first mode when the human detection unit 6 detects the presence of a person based on the detection result of the human detection unit 6. Configured as follows. When the control device 4 performs heating control and raises the room temperature in a state where a person is present in the indoor space 100, volatilization of volatile chemical substances contained in building materials, furniture, and the like in the indoor space 100 is promoted. There is a possibility of harming the health of people in the space 100. Therefore, when the human detection unit 6 detects the presence of a person, the controller 4 does not perform the heating control that raises the room temperature, thereby adversely affecting the health of the person in the indoor space 100. You can avoid giving. When the controller 4 detects the person while the air conditioner 3 is performing the heating control, the operation of the air conditioner 3 is stopped and the ventilator 1 has the indoor space 100. The operation of ventilating the air may be performed. By stopping the operation of the air conditioner 3, volatile chemical substances are less likely to volatilize from building materials or furniture in the indoor space 100. And since the chemical substance in air is discharged | emitted by making the ventilation apparatus 1 ventilate the indoor space 100, possibility of impairing the health of the person in the indoor space 100 is reduced. In this case, the control device 4 may increase the amount of ventilation by the ventilation device 1 more than usual, and can quickly exhaust the air contaminated with the chemical substance.

  Moreover, in the ventilation system of this embodiment, the control apparatus 4 may be provided with the information delivery function which delivers the implementation condition of heating control and ventilation control outside.

  When the control device 4 performs the warming control and the ventilation control, the control device 4 transmits the implementation status to the server 120, so that the server 120 can grasp the implementation status of the warming control and the ventilation control in the indoor space 100. .

  In this ventilation system, as shown in FIG. 6, a display device 130 may be provided that displays the implementation status of heating control and ventilation control distributed by the information distribution function of the control device 4. When the status of heating control and ventilation control in the indoor space 100 is distributed by the information distribution function of the control device 4, the server 120 distributes the control device 4 to the display device 130 registered in advance as a transmission destination. Transfer the implementation status of heating control and ventilation control. The display device 130 is composed of a tablet terminal or a smartphone that can be connected to the wide area communication network 110, and displays the implementation status of the heating control and ventilation control in the indoor space 100 received from the server 120 on the display screen. The user who sees the display content of the display device 130 can grasp the implementation status of the heating control and the ventilation control in the indoor space 100. Therefore, the user who possesses the display device 130 does not enter the indoor space 100 while the air purification control is performed in the indoor space 100 based on the display content of the display device 130, thereby Be careful not to inhale contaminated air.

  In addition, the display device 130 may include an input operation unit (not shown) on which a user performs an input operation in order to operate the ventilation system. When the user operates the input operation unit of the display device 130 and inputs the operation content of the ventilation system, the display device 130 transmits the operation content input using the input operation unit to the control device 4 via the server 120. Upon receiving the operation content transmitted from the display device 130 via the server 120, the control device 4 controls the operations of the air conditioner 3 and the ventilation device 1 based on the operation content.

  When the control device 4 performs the air purification control, the information distribution function of the control device 4 distributes the implementation status of the heating control and the ventilation control to the display device 130. For example, when it is displayed on the display device 130 that the air purification control is performed until 3 hours later, the input operation unit of the display device 130 is used so that a user outside can return to the indoor space 100 after 2 hours 30 minutes. An instruction to end the air purification control by 2 hours and 30 minutes is input. When the user inputs the control content of the ventilation system using the input operation unit of the display device 130, a control signal corresponding to the input content is transmitted from the display device 130 to the control device via the server 120. When the control device 4 receives the control signal transmitted from the display device 130, the operation of the air conditioner 3 and the ventilator 1 is changed so that the air purification control is finished by 2 hours 30 minutes. That is, the control device 4 stops the heating control by the air conditioner 3 after 2 hours and causes the ventilation device 1 to perform the ventilation operation until 2 hours 30 minutes after that time, and the user returns to the indoor space 100. Until then, the volatilized chemical substance can be exhausted out of the indoor space 100. Further, since the air in the indoor space 100 heated to the first temperature T1 by the air conditioner 3 is exhausted to the outside, the room temperature can be brought close to a comfortable level. Here, the display device 130 also serves as an operation device for remotely operating the air conditioner 3 and the ventilation device 1.

  As described above, the ventilation system of the present embodiment includes the ventilation device 1, the measurement device (temperature sensor 2), the air conditioner 3, and the control device 4. The ventilation device 1 includes an intake unit 11 that takes outside air into the indoor space 100 from the outside and an exhaust unit 12 that exhausts the air in the indoor space 100 to the outside. The temperature sensor 2 measures the room temperature of the indoor space 100. The air conditioner 3 adjusts the room temperature of the indoor space 100. The control device 4 controls the operations of the ventilation device 1 and the air conditioning device 3, respectively. The control device 4 is configured to control the operation of the air conditioner 3 so as to perform heating control for raising the room temperature to a predetermined first temperature T1 or higher that is higher than the set temperature range during cooling and heating. In a state where the control device 4 is performing the heating control, the room temperature measured by the temperature sensor 2 exceeds the predetermined second temperature T2 that is higher than the set temperature range and lower than the first temperature T1. When the integrated value is equal to or greater than a predetermined threshold value, the heating control is terminated. And the control apparatus 4 is comprised so that ventilation control which operates the intake part 11 and the exhaust part 12 respectively may be performed.

  Compared with the case where the room temperature is adjusted to the set temperature range by increasing the room temperature of the indoor space 100 to the first temperature T1 or more by performing the heating control, the volatile chemicals are generated from the building materials and furniture in the indoor space 100. Volatile substances can be promoted. And since ventilation control is performed in the state which volatilized the volatile chemical substance from building materials, furniture, etc. by performing heating control, the volatilized chemical substance can be discharged out of the indoor space 100. Therefore, it is possible to reduce the amount of volatile chemical substances remaining in the building materials and furniture in the indoor space 100, and to reduce air pollution in the indoor space 100. Further, the control device 4 stops the ventilation control while performing the heating control to promote the volatilization of the volatile chemical substance, and stops the heating control while performing the ventilation control. The indoor air contaminated with can be ventilated with less power consumption.

  This ventilation system may include an outside air temperature acquisition unit (in this embodiment, the control device 4 is also used) that acquires the outdoor outside air temperature. If the outside air temperature acquired by the outside air temperature acquisition unit is equal to or higher than the first temperature T1, the control device 4 is configured to perform the heating control by operating the air intake unit 11 without operating the air conditioner 3. The If the outside air temperature is equal to or higher than the first temperature T1, introducing the outside air into the indoor space 100 warms the indoor space 100 and promotes volatilization of volatile chemical substances from building materials and furniture. It is possible to reduce the power required for performing the control.

  This ventilation system may include an outside air temperature acquisition unit (in this embodiment, the control device 4 is also used) that acquires the outdoor outside air temperature. If the outside air temperature acquired by the outside air temperature acquisition unit is equal to or lower than a predetermined third temperature T3 lower than the second temperature T2, the control device 4 is configured not to perform the heating control. If the outside air temperature is equal to or lower than the third temperature T3, more electric power is required to warm the room temperature to the first temperature T1 than when the outside air temperature is higher than the third temperature T3. Therefore, if the outside air temperature is equal to or lower than the third temperature T3, the power necessary for volatilizing the volatile chemical substance can be reduced by not performing the heating control.

  In this ventilation system, a human detection unit 6 that detects whether or not a person is present in the indoor space 100 is provided. While the human detection unit 6 detects the presence of a person, the control device 4 performs heating control. It is also preferable to be configured not to perform the above. Since heating control is not performed when there is a person in the indoor space 100, the volatile chemical substance is less likely to volatilize than in the case where heating control is performed, and the volatile chemical substance is in the indoor space 100. The possibility of a person inhaling is reduced.

  In this ventilation system, it is also preferable that the control device 4 has an information distribution function for distributing the implementation status of the heating control and the ventilation control to the outside, and the implementation status of the heating control and the ventilation control can be grasped from the outside. .

  In this ventilation system, it is also preferable to include a display device 130 that displays the implementation status of the heating control and the ventilation control distributed by the information distribution function of the control device 4. The user outside the indoor space 100 can grasp the implementation status of the heating control and ventilation control in the indoor space 100 from the outside by viewing the implementation status displayed on the display device 130.

  In this ventilation system, an operation device for remotely operating the air conditioner 3 and the ventilation device 1 (in the present embodiment, the display device 130 is also used) may be provided. Since the control device 4 controls the operations of the air conditioner 3 and the ventilation device 1 based on the control signal transmitted from the operation device (display device 130), a user outside the room or outside the building operates the operation device. Thus, the air conditioner 3 and the ventilator 1 can be operated remotely.
