Description

  The present invention relates to an indoor environment control system.

  In recent years, many students such as examinees use a cram school to improve their academic performance. However, there are many opportunities for students to stay in comfortable, air-conditioned rooms at the cram school, which reduces autonomic nervous activity due to a decrease in thermoregulatory function and lack of exercise, which improves academic performance. There are indications that it is a contributing factor.

  Also, in general schools, the number of children with hypothermia has increased as a result of school air conditioning and student lifestyle (such as staying up late, irregular eating habits, lack of exercise, etc.). The actual situation is becoming an issue. These signs reduce brain activity and are thought to hinder the improvement of academic work.

  For example, a technique that increases the activity of the autonomic nervous system and maintains / recovers the soundness of the physiological functions of the living body by deliberately applying a light load to the human body from a thermal environment. Therefore, it is considered that such a sound biological function leads to an improvement in academic achievement.

  For example, Patent Document 1 and Patent Document 2 disclose a physiological function activation device that performs a temperature fluctuation operation in which a high temperature holding operation and a low temperature holding operation are alternately performed at least once in order to improve the physiological function activation action. Has been proposed.

  However, since the high temperature holding operation and the low temperature holding operation are executed by the air conditioning function of the room air conditioner in the devices of Patent Documents 1 and 2, it takes time to change the environment from one of the high temperature holding operation and the low temperature holding operation to the other. . If it takes time to change the environment in this way, the student feels uncomfortable for a long time, and the concentration of the student may be hindered. As a result, there may be a decline in grades at a cram school or school where student concentration is an important factor. In addition, a learning cram school and a classroom in a school usually have a larger volume than a room in a general house. In this way, the size of a cram school or school classroom also takes time to change the environment.

  An object of the present invention is to provide an indoor environment control system that can quickly change an indoor environment to a hot or cold environment.

  The indoor environment control system of the present invention includes an air conditioner (2) that performs indoor cooling or heating, an outdoor air introduction device (3) that introduces outdoor air into the room, and a control unit (40), The control unit (40) performs the stimulus applying mode for increasing the amount of outside air introduced into the room more than the air conditioning mode, and then returns the air conditioning device (2) and the outside air introducing device (3) to return to the air conditioning mode. ) To control.

  In the present invention, the stimulus imparting mode for increasing the amount of outside air introduced into the room is performed as compared with the air conditioning mode. In this stimulus application mode, the amount of outside air introduced into the room is increased compared to the normal air conditioning mode. Therefore, during cooling, the room can be temporarily changed to a warm environment using warm air outside, and during heating, The indoor air can be temporarily changed to a cold environment using the cold air outside the room. As described above, in the present invention, in the stimulus application mode, the indoor environment can be quickly brought close to the outdoor environment by using outside air, so that it is possible to quickly change from a comfortable environment in the normal air conditioning mode to a thermal environment or a cold environment in the stimulus application mode. Can be changed. After the stimulus applying mode is performed, the normal air conditioning mode is restored. By switching between the stimulus applying mode and the normal air conditioning mode, warm or cold stimulus (stress) can be given to a person in the room. It is presumed that the activity of the autonomic nerve of the person is increased by increasing the chances of receiving such stimulation, and thus the soundness of the physiological function is regained. Moreover, since the environmental change to the stimulus applying mode is performed quickly, it is possible to suppress a decrease in concentration due to the time required for the environmental change.

  In the indoor environment control system, the control unit (40) controls the air conditioner (2) so that the air conditioning capability of the air conditioner (2) is lower than that in the air conditioning mode in the stimulus applying mode. It is preferable to do this.

  In this configuration, in the stimulus application mode, the air conditioning capacity (cooling capacity) of the air conditioner (2) is made lower than that in the normal air conditioning mode in the stimulus applying mode, so that the room can be quickly brought into the thermal environment. In the stimulus applying mode, the air conditioning capacity (heating capacity) by the air conditioner (2) is made lower than that in the normal air conditioning mode, so that the room can be cooled more quickly. It can be changed to the environment. As a result, the effect of activating the autonomic nerve can be further enhanced, and the decrease in concentration due to the time required for environmental changes can be further suppressed.

In the indoor environment control system, the control unit (40) applies the stimulus between the stimulus applying mode and the air conditioning mode by increasing the air conditioning capability of the air conditioner (2) compared to the air conditioning mode. that controls the air conditioner (2) to perform the return mode to return to the air conditioning mode from the mode.

  In this configuration, since the return mode in which the air conditioning capability is higher than in the normal air conditioning mode is performed, the indoor environment can be changed more quickly from the thermal environment or the cold environment to the comfortable environment in the stimulus applying mode. In this way, it is possible to shorten the transition time from the thermal environment or the cold environment according to the stimulus imparting mode to the comfortable environment according to the air conditioning mode, thereby suppressing a decrease in concentration due to a longer time when the thermal environment or the cold environment is uncomfortable. can do.

In the indoor environment control system, wherein the control unit (40) is in the return mode, than the stimulating mode that controls the outside air introduction device (3) to reduce the introduction amount of the outside air into the chamber.

  In this configuration, in the return mode, the room can be changed to a comfortable environment more quickly by reducing the amount of outside air introduced by the outside air introducing device (3). As a result, the transition time from the thermal environment or the cold environment according to the stimulus applying mode to the comfortable environment according to the air conditioning mode can be further shortened, thereby reducing the concentration due to the longer time when the thermal environment or the cold environment is uncomfortable. Further suppression can be achieved.

Another indoor environment control system of the present invention includes an air conditioner (2) that cools or heats the room, an outside air introduction device (3) that introduces outside air into the room, and a controller (40). The controller (40) performs the stimulus applying mode for increasing the amount of outside air introduced into the room rather than the air conditioning mode, and then returns the air conditioning device (2) and the outside air introducing device to return to the air conditioning mode. The controller (40) controls the outside air so as to reduce the amount of outside air introduced into the room when the room temperature reaches a preset limit temperature in the stimulus applying mode. controlling the introduction apparatus (3).

  In this configuration, a limit temperature for the stimulus applying mode is set in advance, and when the indoor temperature reaches the limit temperature, the amount of outside air introduced is reduced. Therefore, when the cooling is performed, the stimulus applying mode is set. It is possible to suppress an excessively hot environment in the room, and it is possible to suppress an excessively cold environment in the stimulus applying mode when heating is performed.

  In the indoor environment control system, when the time set in advance in the stimulus applying mode has elapsed, the control unit (40) terminates the stimulus applying mode and shifts to the next mode. 2) and the outside air introduction device (3) may be controlled.

  When time is adopted as the termination condition of the stimulus applying mode as in this configuration, the control can be simplified.

  The indoor environment control system includes a setting reception unit (41) that receives data related to a time zone in which the stimulus applying mode is performed, and the control unit (40) receives the time received by the setting reception unit (41). You may control the said external air introduction apparatus (3) so that the said stimulus provision mode may be performed to a belt | band | zone.

  In this configuration, since the user can set in advance the time zone in which the stimulus applying mode is performed, it is possible to clearly distinguish between the time zone in which a person is surely in the room and the time zone in which it is not. Thereby, since the stimulus applying mode is not performed in a time zone when there is no person, wasteful power consumption is prevented. Moreover, since the stimulus applying mode is automatically executed in the set time zone, the stimulus applying mode can be surely executed in the time zone in which a person is present in the room.

  The said indoor environment control system WHEREIN: It is preferable that the said time slot | zone is a time slot | zone according to the time slot | zone of a learning cram school or a school.

  In this configuration, when a cram school or school student is taking a class in the classroom, the stimulus application mode can be automatically performed. In general, students often go to a cram school or school frequently for a long period of time. Therefore, in this configuration, the student can continuously and repeatedly receive the stimulus in the stimulus applying mode for a long period of time at a study school or school. Thereby, it is presumed that the activity of the student's autonomic nerve is increased, and as a result, the soundness of the physiological function is recovered and the recovered soundness is maintained. Such a sound physiological function is thought to lead to an improvement in academic performance.

  According to the present invention, the indoor environment can be quickly changed to a hot environment or a cold environment.

  Hereinafter, an indoor environment control system 1 according to an embodiment of the present invention will be described with reference to the drawings.

[Indoor environment control system]
FIG. 1 is a schematic configuration diagram showing an indoor environment control system 1 according to an embodiment of the present invention. The indoor environment control system 1 according to the present embodiment can effectively give warm or cold stimulus (stress) to a person in the room S by quickly changing the environment of the room S. It is speculated that increasing the opportunity to receive such stimulation will lead to activation of the person's autonomic nerve.

  As shown in FIG. 1, the indoor environment control system 1 includes an air conditioner 2, an outside air introduction device 3, and a controller 4 that controls operations of the air conditioner 2 and the outside air introduction device 3. The controller 4 controls the air conditioner 2 and the outside air introduction device 3 so that the normal air conditioning mode and the stimulus application mode (stress application mode) are performed.

  The air conditioning mode is an operation mode for adjusting the temperature of the room S to air-condition the room S to a comfortable environment. Specifically, in the air-conditioning mode, the room S is adjusted to a comfortable environment by cooling the room S at a time when the outdoor temperature is high (cooling period), such as in summer, and the outdoor temperature is adjusted in winter. The room S is adjusted to a comfortable environment by heating the room S at a low time (heating time). That is, in the air conditioning mode, the air conditioning capability of the air conditioner 2 is controlled so that the temperature of the room S becomes a target temperature (a set temperature T1 described later set by the user).

  The stimulus applying mode is an operation mode for changing the environment of the room S from a comfortable environment to a warm environment or a cool environment. Specifically, in the stimulus application mode, during the cooling period, outside air with a high temperature (more specifically, high temperature and humidity outside air) is introduced into the room S that is adjusted to a comfortable environment by the air conditioning mode with a large air volume. As a result, the room S is changed to a thermal environment at a stretch, and during the heating period, outside air having a low temperature (more specifically, low temperature and humidity) is supplied to the room S adjusted to a comfortable environment by the air conditioning mode with a large air volume. By introducing, the room S is changed to a cold environment at a stretch. In the stimulus imparting mode, control to the set temperature T1 as performed in the air conditioning mode is removed, and the outside air introduction device 3 is controlled so that the room S quickly approaches the outside air environment using outside air.

  When the stimulus application mode ends, the amount of outside air introduced into the room S is reduced as compared to the stimulus application mode (for example, returned to the amount of outside air introduced in the air conditioning mode), and the environment of the room S is controlled by the air conditioning device 2. To return from a warm or cold environment to a comfortable environment (steady state). That is, the temperature and humidity in the room S are quickly returned to the original steady state.

[Air conditioning equipment]
The air conditioner 2 is for cooling or heating the room S. The air conditioner 2 includes a refrigerant circuit 2C that performs a vapor compression refrigeration cycle. The air conditioner 2 includes an outdoor unit 21 and an indoor unit 22. The outdoor unit 21 and the indoor unit 22 are connected to each other via a liquid side communication pipe and a gas side communication pipe.

The compressor 23, the four-way switching valve 24, the outdoor heat exchanger 25, and the expansion mechanism 26 are provided in the outdoor unit 21. The indoor heat exchanger 27 is provided in the indoor unit 22. The outdoor unit 21 is provided with an outdoor fan 28 for supplying outdoor air to the outdoor heat exchanger 25, and the indoor unit 22 is provided with an indoor fan 29 for supplying indoor air to the indoor heat exchanger 27. Is provided.

  In the refrigerant circuit 2 </ b> C, the compressor 23 has a discharge side connected to the first port of the four-way switching valve 24 and a suction side connected to the second port of the four-way switching valve 24. In the refrigerant circuit 2C, an outdoor heat exchanger 25, an expansion mechanism 26, and an indoor heat exchanger 27 are arranged in order from the third port to the fourth port of the four-way switching valve 24.

  The compressor 23 may be a scroll type or rotary type compressor, but is not limited thereto. In the present embodiment, the compressor 23 is configured such that its rotational speed is variable. Specifically, the electric motor of the compressor 23 is connected to a commercial power source via an inverter. When the output frequency of the inverter is changed, the rotational speed of the electric motor changes, and as a result, the rotational speed of the compressor 23 changes. When the rotational speed of the compressor 23 is increased, the operating capacity of the compressor 23 is increased, and when the rotational speed of the compressor 23 is decreased, the operating capacity of the compressor 23 is decreased.

  As the outdoor heat exchanger 25 and the indoor heat exchanger 27, for example, a fin-and-tube heat exchanger can be used, but is not limited thereto. The outdoor heat exchanger 25 exchanges heat between the outdoor air and the refrigerant in the refrigerant circuit 2C. The indoor heat exchanger 27 exchanges heat between the indoor air and the refrigerant in the refrigerant circuit 2C. The expansion mechanism 26 can use, for example, an expansion valve such as an electronic expansion valve, but is not limited thereto.

  The four-way switching valve 24 has a first state in which the first port communicates with the third port and the second port communicates with the fourth port (state indicated by a solid line in FIG. 1), and the first port The state is switched to a second state (a state indicated by a broken line in FIG. 1) that communicates with the fourth port and the second port communicates with the third port. The air conditioner 2 performs a cooling operation when in the first state, and performs a heating operation when in the second state.

  The indoor environment control system 1 includes a temperature sensor 11 that measures the temperature of the air in the room S. In the present embodiment, the temperature sensor 11 is provided in the indoor unit 22. Specifically, the temperature sensor 11 can be provided, for example, in the vicinity of the suction port that sucks the air in the room S into the housing 20 of the indoor unit 22. However, the temperature sensor 11 only needs to be provided in a place where the temperature of the air in the room S can be measured. For example, the temperature sensor 11 may be provided on the ceiling of the room. For example, a remote controller or the like, or may be provided in the outside air introduction device 3. Further, the temperature sensor 11 may be provided in each of the air conditioner 2 and the outside air introduction device 3. The controller 4 controls the operation of the air conditioner 2 and the outside air introduction device 3 based on the detection result of the temperature sensor 11.

  In the present embodiment, the indoor unit 22 is a ceiling-mounted indoor unit such as a ceiling-embedded type or a ceiling-suspended type, but is not limited to this, and other types of indoor units such as a wall-mounted type and a floor-standing type are used. It may be a machine.

[Outside air introduction device]
The outside air introduction device 3 is for introducing outside air into the room S. The outside air introduction device 3 includes an air supply path that guides the outside air into the room S and a fan 31 that sends outside air to the room S through the air supply path.

  The fan 31 may be configured to have a constant rotation speed, but may be configured to have a variable rotation speed. When the rotation speed is variable, the rotation speed may be configured to change stepwise. Specifically, for example, the electric motor of the fan 31 may be configured to be switchable between an “H mode” in which the outside air introduction amount is the largest and an “L mode” in which the outside air introduction amount is the smallest. In this case, the electric motor of the fan 31 can adjust the air volume in a plurality of stages including a stop mode in which the outside air is not introduced into the room S, an L mode in which the outside air introduction amount is small, and an H mode in which the outside air introduction amount is large. Configured.

  Moreover, the electric motor of the fan 31 may be connected to a commercial power supply via an inverter. In this case, when the output frequency of the inverter is changed, the rotational speed of the electric motor changes, and as a result, the rotational speed of the fan 31 changes. When the rotation speed of the fan 31 is increased, the amount of outside air introduced into the room S by the fan 31 is increased, and when the rotation speed of the fan 31 is decreased, the amount of outside air introduced into the room S by the fan 31 is decreased.

  Further, the outside air introduction device 3 may include a plurality of fans 31. In this case, the amount of outside air introduced can be changed according to the number of fans 31 to be operated.

  In the present embodiment, the outside air introduction device 3 includes a housing 30, ducts 32 and 33, and an air outlet 34. The fan 31 is accommodated in the housing 30. In the present embodiment, the duct 32, the housing 30, the duct 33, and the air outlet 34 are arranged in this order to constitute the air supply path.

  When the fan 31 is operated, outside air flows into the housing 30 through the duct 32, is sent to the air outlet 34 through the duct 33, and is supplied to the room S from the air outlet 34. In this embodiment, although the blower outlet 34 is provided in the ceiling of the room, it is not restricted to this, For example, you may be provided in the side wall of the room.

  As the fan 31, various blowers such as a centrifugal fan, a mixed flow fan, an axial fan, and a cross flow fan can be used. For example, when an axial fan as the fan 31 is attached to the air outlet 34 provided on the side wall of the room, the housing 30 and the ducts 32 and 33 can be omitted. In this case, the air supply path is constituted by an air outlet 34 provided on the side wall.

  The outside air introduction device 3 may further have an exhaust path, but if the airtightness of the room is not so high, the exhaust path can be omitted. The exhaust path is not particularly limited as long as it can exhaust the air in the room S to the outside. The exhaust path may be configured only by openings provided in a ceiling, a side wall or the like. The exhaust path may include an unillustrated exhaust duct connected to an opening provided in a ceiling, a side wall or the like. An exhaust fan (not shown) may be provided in the exhaust path.

  Further, the outside air introduction device 3 may be a ventilation device provided with a total heat exchanger (not shown). The total heat exchanger causes heat exchange between sensible heat and latent heat between the outside air flowing through the air supply path and the air from the room S flowing through the exhaust path. However, from the viewpoint of quickly changing the environment of the room S from the comfortable environment to the thermal environment or the cold environment in the stimulus imparting mode, it is preferable to supply the outdoor air as it is to the room S without using a total heat exchanger. .

  In the present embodiment, the outside air introduction device 3 is provided on the ceiling (specifically, the back of the ceiling), but is not limited thereto, and may be provided, for example, on the side wall of the room or on the floor. Also good.

[controller]
The controller 4 controls the air conditioner 2 and the outside air introduction device 3 so that the normal air conditioning mode and the stimulus applying mode are performed. The air conditioning mode includes a cooling operation mode and a heating operation mode. The controller 4 has a CPU, a memory, and the like. The controller 4 may be provided in the air conditioning apparatus 2, may be provided in the outside air introduction apparatus 3, or may be provided in a place different from these. The controller 4 is connected to the air conditioner 2, the outside air introduction device 3, the temperature sensor 11, and the like via a communication line (not shown), and can transmit / receive information to / from them. Note that transmission / reception of information may be performed wirelessly instead of a communication line.

  The controller 4 includes a control unit 40 that executes a normal air-conditioning mode and various operation modes such as a stimulus application mode, a setting reception unit 41 that receives input from a user, and a time measurement unit 42 as functions. Yes. The control unit 40 includes an air conditioning control unit that controls the air conditioner 2 and an outside air introduction control unit that controls the outside air introduction device 3. In the present embodiment, the control unit 40 controls the air conditioner 2 and the outside air introduction device 3 so as to return to the air conditioning mode after performing the stimulus imparting mode that increases the amount of outside air introduced into the room S rather than the air conditioning mode. .

  The setting receiving unit 41 has a function of receiving, for example, a set temperature of the room S in the air conditioning mode, a set value of a time zone for performing the stimulus applying mode, a set value of a limit temperature in the stimulus applying mode, and the like from the user. The control unit 40 controls the air conditioner 2 and the outside air introduction device 3 based on the data such as the set temperature, the time zone, the limit temperature, the data input from the temperature sensor 11 and the like, and performs various operation modes. Execute.

  The time measuring unit 42 has a clock function. Further, the time measuring unit 42 may have a timer function, a calendar function, and the like. Based on the clock function of the time measuring unit 42, the control unit 40 can determine, for example, whether it is a time zone in which the stimulus applying mode is executed.

[Driving operation]
In the normal air conditioning mode, the controller 40 of the controller 4 controls the compressor 23, the expansion mechanism 26, the outdoor fan 28, the indoor fan 29, and the like so that the temperature of the room S approaches the set temperature set by the user. Thus, cooling operation or heating operation is performed. Specifically, the control unit 40 adjusts the flow rate of the refrigerant flowing through the refrigerant circuit 2C by changing the opening of the expansion mechanism 26, changes the rotational speed of the compressor 23, and increases or decreases the operating capacity of the compressor 23. The air conditioning capacity is adjusted by adjusting the air volume by the outdoor fan 28 and the air volume by the indoor fan 29.

  In the refrigerant circuit 2C during the cooling operation, the refrigeration cycle is performed with the four-way switching valve 24 set to the first state. In this state, the refrigerant circulates in the order of the outdoor heat exchanger 25, the expansion mechanism 26, and the indoor heat exchanger 27. The outdoor heat exchanger 25 functions as a condenser, and the indoor heat exchanger 27 functions as an evaporator. In the outdoor heat exchanger 25, the refrigerant discharged from the compressor 23 dissipates heat to the outdoor air and condenses. On the other hand, in the indoor heat exchanger 27, the refrigerant expanded when passing through the expansion mechanism 26 absorbs heat from the indoor air and evaporates. The indoor unit 22 supplies the sucked indoor air to the indoor heat exchanger 27 and blows out the air cooled in the indoor heat exchanger 27 into the room S.

  In the refrigerant circuit 2C during the heating operation, the refrigeration cycle is performed with the four-way switching valve 24 set to the second state. In this state, the refrigerant circulates in the order of the indoor heat exchanger 27, the expansion mechanism 26, and the outdoor heat exchanger 25. The indoor heat exchanger 27 functions as a condenser, and the outdoor heat exchanger 25 functions as an evaporator. In the indoor heat exchanger 27, the refrigerant discharged from the compressor 23 dissipates heat to the indoor air and condenses. The indoor unit 22 supplies the sucked indoor air to the indoor heat exchanger 27 and blows out the air heated in the indoor heat exchanger 27 into the room S. On the other hand, in the outdoor heat exchanger 25, the refrigerant expanded when passing through the expansion mechanism 26 absorbs heat from the outdoor air and evaporates.

  In the stimulus application mode, the control unit 40 of the controller 4 controls the outside air introduction device 3 so that outside air is introduced into the room S. The control unit 40 controls the outside air introduction device 3 so that the amount of outside air introduced into the room S in the stimulus applying mode is larger than the amount of outside air introduced into the room S in the air conditioning mode. In the normal air conditioning mode, the control unit 40 may stop the operation of the outside air introduction device 3 so as not to introduce outside air into the room S, and the outside air introduction device 3 is introduced so as to introduce outside air into the room S. You may drive.

  In this embodiment, it is preferable that the stimulus applying mode is performed in a time zone in which there is a certain person in the room S. For example, when the time zone in which the person is in the room S has a certain degree of regularity, it is preferable that the schedule for performing the stimulus application mode is determined in advance and the stimulus application mode is automatically executed. To give a specific example, for example, in the case of aiming to improve the academic achievement by activating the autonomic nerves by applying heat or cold stress to a student in a cram school or school, the time zone in which the stimulus applying mode is performed is , Set to suit the time of the school cram or school class. Then, in a time zone other than the set time zone, the stimulus applying mode is not performed, and the normal air conditioning mode is performed, or the operation of the air conditioner 2 and the outside air introduction device 3 is stopped.

  Hereinafter, although the control example of the indoor environment control system 1 of this embodiment is demonstrated concretely, control of the indoor environment control system 1 is not restricted to the following control examples.

[Control Example 1]
2A and 2B are time charts showing a control example 1 of the indoor environment control system 1 according to the embodiment. 2A and 2B show the timing at which the air conditioning mode and the stimulus imparting mode are performed as time passes, and the solid line shows the change in the temperature of the room S. FIG. FIG. 2 (A) shows an example of control at the cooling time, and FIG. 2 (B) shows an example of control at the heating time. As shown in FIGS. 2 (A) and 2 (B), in the indoor environment control system 1, the normal air conditioning mode is performed, then the stimulus applying mode is performed, and when the stimulus applying mode ends, the air conditioning mode is restored. It is.

  In the control example 1, the time zone in which the stimulus applying mode is performed is set in advance by the user so as to match the time zone of the learning cram school or school. That is, the setting reception unit 41 of the controller 4 receives the setting of the time zone by the user, and the control unit 40 performs the stimulus applying mode in the time zone received by the setting reception unit 41 and The outside air introducing device 3 is controlled.

  As shown in FIGS. 2A and 2B, in the control example 1, the normal air conditioning mode and the stimulus applying mode are alternately executed in the set time zone. In the control example 1, the stimulus applying mode is repeatedly performed within the set time. That is, in the control example 1, the stimulus applying mode is executed a plurality of times in the set time period, but the present invention is not limited to this, and the stimulus applying mode may be performed only once in the set time period.

  The stimulus applying mode may be performed when a predetermined time elapses after the air conditioning mode is started. Further, the stimulus applying mode may be performed when a predetermined time elapses after the temperature of the room S reaches the set temperature T1 in the air conditioning mode. In addition, when the stimulus application mode is executed a plurality of times in the set time zone, the stimulus application mode may be performed, for example, at regular intervals.

  FIG. 3 is a schematic diagram illustrating a state when the room S is controlled to a comfortable environment by the normal air conditioning mode in the indoor environment control system 1 according to the embodiment. As shown in FIGS. 2A, 2 </ b> B, and 3, in the air conditioning mode, the control unit 40 controls the air conditioner 2 so that the temperature in the room S approaches the set temperature T <b> 1 set by the user. . In the air conditioning mode shown in FIG. 3, the operation of the outside air introduction device 3 is stopped, and the temperature of the room S is adjusted to the set temperature T1 by the air conditioner 2 in a state where the outside air is not introduced into the room S. It is not limited to this. In the air conditioning mode, the air conditioner 2 and the outside air introduction device 3 operate so as to adjust the temperature of the room S to the set temperature T1 while operating the outside air introduction device 3 to continuously or intermittently introduce the outside air into the room S. It may be controlled. However, in this case, the amount of outside air introduced by the outside air introducing device 3 is suppressed to be small so that the air conditioning load in the room S does not become excessively high (for example, set to the above-described “L mode”).

  FIG. 4 is a schematic diagram illustrating a state in the room environment control system 1 according to the embodiment when the room S is controlled to a warm environment or a cool environment by the stimulus applying mode. As shown in FIGS. 2A, 2 </ b> B, and 4, in the stimulus application mode, the control unit 40 controls the outside air introduction device 3 so as to increase the amount of outside air introduced into the room S compared to the air conditioning mode. . In the stimulus imparting mode shown in FIG. 4, the operation of the air conditioner 2 is stopped, and the outside air introduction device 3 introduces the outside air into the room S in a state where the air conditioner 2 is not air-conditioned. It is done, but it is not limited to this. In the stimulus application mode, the air conditioner 2 and the outside air introduction device 3 may be controlled so as to introduce outside air into the room S while operating the air conditioner 2 to air-condition the room S.

  However, in the stimulus application mode, from the viewpoint of quickly bringing the environment of the room S closer to the outdoor environment, the control unit 40 performs air conditioning so that the air conditioning capability of the air conditioner 2 is lower in the stimulus application mode than in the air conditioning mode. The device 2 is preferably controlled.

Examples of the control for lowering the air conditioning capability in the stimulus imparting mode than the air conditioning capability in the air conditioning mode include the following means (A) to (E), but are not limited thereto.
(A) The air conditioning operation by the air conditioner 2 is stopped in the stimulus application mode.
(B) The operating capacity of the compressor 23 is set to the minimum value in the stimulus application mode (in this case, it is preferable to remove the control to bring the temperature of the room S close to the set temperature T1).
(C) In the stimulus application mode, the set temperature for air conditioning is set to a value larger than the set temperature T1 in the cooling period, and the set temperature for air conditioning is a value smaller than the set temperature T1 in the heating period. Set to
(D) When a plurality of indoor units 22 are arranged in the room, the number of indoor units 22 operated in the stimulus applying mode is made smaller than the number of indoor units 22 operated in the air conditioning mode.
(E) The air volume blown from the indoor unit 22 in the stimulus imparting mode is lower than the air volume blown from the indoor unit 22 in the air conditioning mode.

  In addition, in the stimulus imparting mode, when stopping the air conditioning operation by the air conditioning apparatus 2, the compressor 23 is stopped, but the indoor fan 29 may be operating. When the temperature sensor 11 is provided in the indoor unit 22, the temperature of the room S can be continuously detected by the temperature sensor 11 by operating the indoor fan 29. If the temperature sensor 11 is provided at a position where the temperature of the room S can be detected even if the indoor fan 29 is stopped, the indoor fan 29 may be stopped while the air conditioning operation is stopped.

  FIG. 5 is a flowchart illustrating a specific example of the control example 1 of the indoor environment control system 1 according to the embodiment. As shown in FIGS. 2A, 2B, and 5, the control unit 40 first controls the air conditioner 2 and the outside air introduction device 3 so that the normal air conditioning mode is performed (in FIG. 5). Step S1). As shown in FIGS. 2A and 2B, in the air conditioning mode, the room S is air-conditioned so that the temperature of the room S approaches the set temperature T1.

  Next, the control unit 40 determines whether or not an air conditioning mode end condition (next mode start condition) is satisfied (step S2). If the condition for ending the air conditioning mode is not satisfied (NO in step S2), the air conditioning mode is continued. If the air conditioning mode termination condition is satisfied (YES in step S2), the control unit 40 terminates the normal air conditioning mode and the stimulus applying mode is performed, so that the air conditioner 2 and the outside air introduction device 3 are performed. Is controlled (step S3).

  As an end condition of the air conditioning mode, for example, an elapsed time after the start of the normal air conditioning mode can reach a preset reference time, but is not limited thereto. The termination condition of the air conditioning mode may be, for example, that a predetermined time elapses after the temperature of the room S reaches the set temperature T1. Moreover, the termination condition of the air conditioning mode may be based on the elapsed time since the lesson started. Further, the normal mode end condition may be, for example, a condition associated with the time zone received by the setting receiving unit 51. Specifically, the air condition mode end condition may be based on the elapsed time from the start time of the accepted time zone, for example. In this case, in this embodiment, the end condition of the normal mode is that the elapsed time from the start time of the lesson (the start time of the time zone) reaches a predetermined time (for example, 30 minutes after the lesson starts). It can be a condition.

  In the stimulus imparting mode, since the outdoor air is introduced into the room S by the outside air introduction device 3, the room S can be brought close to the outdoor environment quickly. Specifically, in the stimulus application mode, the air temperature in the room S rises to a temperature T2 in a short time as shown in FIG. In the stimulus applying mode, the air temperature in the room S drops to the temperature T2 in a short time as shown in FIG. These temperatures T2 may be the same as the outdoor air temperature, or may be a temperature between the outdoor air temperature and the set temperature T1 in the air conditioning mode.

  In the control example 1, the control unit 40 may control the outside air introduction device 3 so as to reduce the amount of outside air introduced into the room when the temperature of the room S reaches a preset limit temperature in the stimulus application mode. Good. The limit temperature can be set to a value closer to the outdoor temperature than the set temperature T1 of the air conditioning mode, but is not limited thereto. The limit temperature at the cooling time is a value larger than the set temperature T1 and smaller than the outdoor temperature. The limit temperature in the heating time is a value smaller than the set temperature T1 and larger than the outdoor temperature. In this case, when the temperature of the room S reaches the limit temperature in the stimulus application mode, the amount of outside air introduced is reduced. Therefore, when the cooling is performed, the room S is excessively heated in the stimulus application mode. It is possible to prevent the room S from becoming an excessively cold environment in the stimulus applying mode at the time when heating is performed.

  However, in the stimulus application mode, the above limit temperature may not be set. In this case, in the stimulus application mode, for example, the amount of outside air introduced into the room S is controlled to be constant.

  Next, the control unit 40 determines whether or not an end condition (start condition for the next mode) of the stimulus application mode is satisfied (step S4). When the stimulus application mode end condition is not satisfied (NO in step S4), the stimulus application mode is continued. When the stimulus application mode end condition is satisfied (YES in step S4), the control unit 40 ends the stimulus application mode and the normal air conditioning mode is performed so that the air conditioner 2 and the outside air introduction device are performed. 3 is controlled (step S1).

  As an end condition of the stimulus application mode, for example, an elapsed time from the start of the stimulus application mode can reach a preset reference time t1, but is not limited thereto. The termination condition of the stimulus applying mode may be, for example, that a predetermined time elapses after the temperature of the room S reaches a predetermined temperature in the stimulus applying mode. The time from the start to the end of the stimulus application mode (time t1 in FIGS. 2A and 2B) is not particularly limited, but is in the range of about a few minutes to a few dozen minutes (specifically For example, about 5 to 10 minutes). Further, the termination condition of the stimulus applying mode can be a condition that a predetermined time is reached.

  When the stimulus applying mode is switched to the normal air conditioning mode, the air conditioner 2 is controlled so that the air temperature in the room S approaches the set temperature T1. In the control example 1, in the air conditioning mode, it takes time t2 to return from the temperature T2 of the room S at the end of the stimulus applying mode to the set temperature T1. In order to further shorten the time t2, control may be performed as in the following control example 2.

[Control Example 2]
6A and 6B are time charts showing a control example 2 of the indoor environment control system 1 according to the embodiment. FIG. 6 (A) shows an example of control at the cooling time, and FIG. 6 (B) shows an example of control at the heating time. FIG. 7 is a schematic diagram showing a state in the indoor environment control system 1 when the room S is returned from the thermal environment or the cold environment to the comfortable environment by the return mode.

  The control example 2 is different from the control example 1 in that the return mode is performed, and the other control is the same as the control example 1. In the control example 2, the control unit 40 performs a return mode between the stimulus applying mode and the air conditioning mode to increase the air conditioning capability of the air conditioner 2 over the air conditioning mode and return from the stimulus applying mode to the air conditioning mode. The air conditioner 2 is controlled. In this control example 2, since the return mode in which the air conditioning capability is higher than that in the normal air conditioning mode is performed, the indoor environment can be quickly changed from the stimulus imparting mode to the normal air conditioning mode.

  FIG. 8 is a flowchart showing a control example 2 of the indoor environment control system 1. Steps S1 to S4 in FIG. 8 are the same as steps S1 to S4 in Control Example 1 shown in FIG.

  If the end condition (start condition for the next mode) of the stimulus application mode is satisfied (YES in step S4), the control unit 40 ends the stimulus application mode and performs the return mode so that the return mode is performed. The device 2 and the outside air introduction device 3 are controlled (step S5).

In the return mode, in order to quickly return to the comfortable environment, the air conditioning capability of the air conditioner 2 is enhanced as compared with the normal air conditioning mode. As control for making the air conditioning capability in the return mode higher than the air conditioning capability in the normal air conditioning mode, the following means (F)-(I) can be exemplified, but not limited thereto.
(F) In the return mode, the operating capacity of the compressor 23 is set to the maximum value.
(G) In the return mode, the set temperature for air conditioning is set to a value smaller than the set temperature T1 in the cooling period, and the set temperature for air conditioning is set to a value greater than the set temperature T1 in the heating period. Is set.
(H) When a plurality of indoor units 22 are arranged in the room, the number of indoor units 22 operated in the return mode is made larger than the number of indoor units 22 operated in the air conditioning mode.
(I) The air volume blown from the indoor unit 22 in the return mode is set higher than the air volume blown from the indoor unit 22 in the air conditioning mode.

  In the return mode, it is preferable to stop the operation of the outside air introduction device 3 as shown in FIG. 7 from the viewpoint of promptly returning to a comfortable environment without being affected by outdoor air as much as possible.

  As a condition for ending the return mode (start condition for the next mode), for example, it can be a condition whether or not the temperature in the room S has reached a predetermined reference temperature (for example, the set temperature T1). It is not limited to this. The reference temperature may be a value different from the set temperature T1. Further, the end condition of the return mode may be that the elapsed time from the start of the return mode reaches a preset reference time.

  In the control example 2, in the return mode, it takes time t3 to return from the temperature T2 of the room S at the end of the stimulus applying mode to the set temperature T1. This time t3 is shorter than the time t2 of the control example 1.

  The control unit 40 determines whether or not the return mode end condition is satisfied (step S6). When the return mode end condition is not satisfied (NO in step S6), the return mode is continued. If the end condition for the return mode is satisfied (YES in step S6), the control unit 40 causes the air conditioner 2 and the outside air introduction device 3 to end the return mode and perform the normal air conditioning mode. Control (step S1).

[Summary of Embodiment]
In this embodiment, since the introduction amount of the outside air into the room is increased in the stimulus applying mode as compared with the normal air conditioning mode, the room can be quickly changed into a thermal environment using warm air outside the room during cooling. During heating, the room can be rapidly changed to a cold environment by using cold air outside the room. Accordingly, since the indoor environment can be quickly brought close to the outdoor environment by using outside air in the stimulus application mode, it is possible to quickly change from the comfortable environment in the normal air conditioning mode to the warm environment or the cool environment in the stimulus application mode. After the stimulus applying mode is performed, the normal air conditioning mode is restored. By switching between the stimulus applying mode and the normal air conditioning mode, warm or cold stimulus (stress) can be given to a person in the room. It is presumed that the activity of the autonomic nerve of the person is increased by increasing the chances of receiving such stimulation, and thus the soundness of the physiological function is regained. Moreover, since the environmental change to the stimulus applying mode is performed quickly, it is possible to suppress a decrease in concentration due to the time required for the environmental change.

  In this embodiment, the control part 40 controls the air conditioning apparatus 2 so that the air conditioning capability by the air conditioning apparatus 2 is lower than that in the air conditioning mode in the stimulus imparting mode. Specifically, at the time when cooling is performed, in the stimulus application mode, the air conditioning capacity (cooling capacity) by the air conditioning apparatus 2 is made lower than in the normal air conditioning mode, thereby changing the room to a thermal environment more quickly. In the stimulus applying mode, the air conditioning capability (heating capability) by the air conditioner 2 is made lower than that in the normal air conditioning mode in the stimulus applying mode, thereby changing the room to the cold environment more quickly. be able to. As a result, the effect of activating the autonomic nerve can be further enhanced, and the decrease in concentration due to the time required for environmental changes can be further suppressed.

  In the control example 2 of the present embodiment, the control unit 40 restores from the stimulus applying mode to the air conditioning mode by increasing the air conditioning capability of the air conditioner 2 between the stimulus applying mode and the air conditioning mode. The air conditioner 2 is controlled to perform the mode. Therefore, the indoor environment can be changed more quickly from the hot or cold environment in the stimulus applying mode to the comfortable environment. In this way, it is possible to shorten the transition time from the thermal environment or the cold environment according to the stimulus imparting mode to the comfortable environment according to the air conditioning mode, thereby suppressing a decrease in concentration due to a longer time when the thermal environment or the cold environment is uncomfortable. can do.

  In the control example 2 of the present embodiment, the control unit 40 controls the outside air introduction device 3 in the return mode so as to reduce the amount of outside air introduced into the room more than in the stimulus application mode. Therefore, the room S can be changed to the comfortable environment more quickly. As a result, the transition time from the thermal environment or the cold environment according to the stimulus applying mode to the comfortable environment according to the air conditioning mode can be further shortened, thereby reducing the concentration due to the longer time when the thermal environment or the cold environment is uncomfortable. Further suppression can be achieved.

  In the present embodiment, the control unit 40 controls the outside air introduction device 3 so as to reduce the amount of outside air introduced into the room S when the temperature of the room S reaches a preset limit temperature in the stimulus application mode. Is preferred. In this control example, when the temperature of the room S reaches this limit temperature, the amount of outside air introduced is reduced, so that it is possible to prevent the room S from becoming an excessively warm environment in the stimulus application mode during the cooling period. In the period when heating is performed, the room S can be prevented from becoming excessively cold in the stimulus applying mode.

  In the present embodiment, the controller 40 controls the air conditioner 2 and the outside air introduction device 3 so as to end the stimulus application mode and shift to the next mode when a preset time has elapsed in the stimulus application mode. May be. When time is adopted as the termination condition of the stimulus applying mode as in this configuration, the control can be simplified.

  In the present embodiment, the control unit 40 controls the outside air introduction device 3 to perform the stimulus application mode in the time zone received by the setting reception unit 41. Therefore, since the user can set in advance the time zone in which the stimulus applying mode is performed, it is possible to clearly distinguish the time zone in which the person is surely in the room S from the time zone in which the person is not. Thereby, since the stimulus imparting mode is not performed in a time zone when there is no person, it is possible to prevent wasteful power consumption. Moreover, since the stimulus applying mode is automatically executed in the set time zone, the stimulus applying mode can be surely executed in the time zone in which a person is present in the room.

  In the present embodiment, the stimulus imparting mode is executed in a time zone corresponding to a time zone of a learning cram school or school class. Therefore, when a cram school or school student is taking a class in the classroom, the stimulus imparting mode can be automatically performed. And the student can receive the stimulus by the stimulus imparting mode continuously and repeatedly for a long period of time at a school or school. Thereby, it is presumed that the activity of the student's autonomic nerve is increased, and as a result, the soundness of the physiological function is recovered and the recovered soundness is maintained. Such a sound physiological function is thought to lead to an improvement in academic performance.

  Note that the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made without departing from the spirit of the present invention.

  In the above embodiment, the case where the stimulus imparting mode is performed in the time zone of the school cram school or the school class (the time zone in which the student is seated) is illustrated, but the present invention is not limited to this. The stimulus applying mode may be performed at the place.

  In the embodiment, the control unit 40 controls the outside air introduction device 3 so as to reduce the amount of outside air introduced into the room S when the temperature of the room S reaches a preset limit temperature in the stimulus application mode. Not limited to this. The control unit 40 may control the outside air introduction device 3 so that the amount of outside air introduced into the room S does not decrease from the start to the end of the stimulus imparting mode.

  In the above-described embodiment, the setting reception unit 41 that receives data related to the time period in which the stimulus applying mode is performed is provided. However, the setting reception unit 41 may be omitted.
