Description

The present invention relates to a building, a building air conditioning method, and a building air conditioning system.

There is a known air conditioning method in which a first area to be air-conditioned in a building is connected to a second area different from the first area by a duct, and air from the second area is sent to the first area through the duct (see, for example, Patent Document 1). The air conditioning method disclosed in Patent Document 1 determines the season at the time, and determines the amount of air to be sent from the second area to the first area depending on the season.

JP 2018-84381 A

However, air conditioning methods that only take into account the season cannot reflect the daily temperature difference, so it is not possible to maintain a comfortable temperature and there is a risk of air conditioning efficiency decreasing.

Therefore, the present invention aims to provide a building, a building air conditioning method, and a building air conditioning system that can efficiently air condition the area to be air-conditioned.

In order to achieve the above-mentioned object, a building of the present invention has a first area to be air-conditioned, a second area different from the first area, a heat transfer unit capable of transferring heat from the second area to the first area, and a control unit that controls driving of the heat transfer unit based on temperature information of the first area and temperature information of the second area, wherein when a temperature according to the temperature information of the first area is lower than a predetermined set temperature and a temperature according to the temperature information of the second area is higher than a temperature according to the temperature information of the first area, the control unit drives the heat transfer unit to supply air from the second area to the first area until the temperature of the first area reaches the temperature of the second area, thereby heating the first area, and when a temperature according to the temperature information of the first area is higher than the predetermined set temperature and a temperature according to the temperature information of the second area is lower than a temperature according to the temperature information of the first area, the control unit drives the heat transfer unit to supply air from the second area to the first area until the temperature of the first area reaches the temperature of the second area, thereby cooling the first area.

Further, an air conditioning method for a building according to the present invention is an air conditioning method for a building having a first area to be air-conditioned in a building, a second area in the building different from the first area, and a heat transfer unit capable of transferring heat of the second area to the first area, the method controlling drive of the heat transfer unit based on temperature information of the first area and temperature information of the second area, and when a temperature according to the temperature information of the first area is lower than a predetermined set temperature and a temperature according to the temperature information of the second area is higher than a temperature according to the temperature information of the first area, driving the heat transfer unit to supply air of the second area to the first area until the temperature of the first area reaches a temperature of the second area, thereby heating the first area, and when a temperature according to the temperature information of the first area is higher than the predetermined set temperature and a temperature according to the temperature information of the second area is lower than a temperature according to the temperature information of the first area, driving the heat transfer unit to supply air of the second area to the first area until the temperature of the first area reaches a temperature of the second area, thereby cooling the first area.

Moreover, the air conditioning system for a building according to the present invention includes a heat transfer unit capable of transferring heat from a second area different from the first area in a building to a first area to be air-conditioned in the building, and a control unit that controls driving of the heat transfer unit based on temperature information of the first area and temperature information of the second area, wherein when a temperature according to the temperature information of the first area is lower than a predetermined set temperature and a temperature according to the temperature information of the second area is higher than a temperature according to the temperature information of the first area, the control unit drives the heat transfer unit to supply air from the second area to the first area until the temperature of the first area reaches the temperature of the second area, thereby heating the first area, and when a temperature according to the temperature information of the first area is higher than the predetermined set temperature and a temperature according to the temperature information of the second area is lower than a temperature according to the temperature information of the first area, the control unit drives the heat transfer unit to supply air from the second area to the first area until the temperature of the first area reaches the temperature of the second area, thereby cooling the first area.

In the present invention, when the first area is conditioned using heat from the second area, the heat transfer section is controlled based on temperature information from the first area and temperature information from the second area, so that the first area can be efficiently brought to the desired temperature and the first area can be maintained at a comfortable temperature.
The present invention includes not only a case in which, when the second area is hotter than the first area, the heat transfer unit transfers heat (hot heat) from the second area to the first area to heat the first area, but also a case in which, when the second area is colder than the first area, the heat transfer unit transfers heat (cold heat) from the second area to the first area to cool the first area.

In the building according to the present invention, the second area may be a high solar radiation obtaining area that can obtain a larger amount of solar radiation than the first area.
With this configuration, the second area is often hotter than the first area during the day, so when heat is transferred from the second area to raise the temperature of the first area, it is easy to raise the temperature of the first area.
A high solar radiation acquisition area is, for example, an area that faces south, east, west, southeast, or southwest, has an opening (window) through which sunlight streams in, and the area ratio of the opening to the wall facing the outside (exterior wall) in which the opening is located is 30% or more.

In the building according to the present invention, the second area may be provided with an air conditioner.
With this configuration, the air in the second area, which has been brought to a comfortable temperature and humidity by the air conditioner, can be transferred to the first area, thereby making the temperature in the first area comfortable.

In the building according to the present invention, the heat transfer section may be configured to be able to blow air from the second area to the first area.
With this configuration, by blowing air (warm air/cold air) from the second area to the first area, heat from the second area can be easily transferred to the first area.

In addition, in the building of the present invention, the heat transfer section may have a duct that connects the first area and the second area, and a blower that blows air from the second area to the first area through the duct.
With this configuration, the air (hot air/cold air) in the second area can be easily sent to the first area. Even if an air conditioner cannot be installed in the first area, the first area can be air-conditioned simply by providing a duct outlet.

In addition, in the building of the present invention, the heat transfer section has an upper outlet and a lower outlet for blowing air from the second area to the first area, the upper outlet being located above the lower outlet, and when the temperature of the second area is higher than the temperature of the first area, the air from the second area is blown from the lower outlet to the first area, and when the temperature of the second area is lower than the temperature of the first area, the air from the second area is blown from the upper outlet to the first area.
With this configuration, the air (warm air/cold air) from the second area supplied to the first area can be efficiently mixed with the air from the first area by utilizing the temperature difference.

In addition, in the building according to the present invention, the heat transfer section may have a latent heat storage material capable of storing heat in the second area and dissipating the stored heat to the first area.
With this configuration, the time period for storing heat and the time period for releasing heat can be shifted. For example, the heat in the second area that has become hot due to solar radiation during the day can be stored in the latent heat storage material, and the heat stored in the latent heat storage material can be released to the first area at night.

In addition, in the building according to the present invention, when the temperature according to the temperature information of the first area is lower than a preset temperature and the temperature according to the temperature information of the second area is higher than the temperature according to the temperature information of the first area, the control unit may drive the heat transfer unit to heat the first area.

In addition, in the building air conditioning method according to the present invention, when the temperature according to the temperature information of the first area is lower than a preset temperature and the temperature according to the temperature information of the second area is higher than the temperature according to the temperature information of the first area, the heat transfer unit may transfer heat from the second area to the first area to heat the first area.

This configuration allows the heat from the second area to be used to heat the first area efficiently and without waste.

In addition, in the building air conditioning method according to the present invention, when the temperature according to the temperature information of the first area is higher than a preset temperature and the temperature according to the temperature information of the second area is lower than the temperature according to the temperature information of the first area, the control unit may drive the heat transfer unit to cool the first area.

In addition, in the building air conditioning method according to the present invention, when the temperature according to the temperature information of the first area is higher than a preset temperature and the temperature according to the temperature information of the second area is lower than the temperature according to the temperature information of the first area, the heat transfer unit may transfer heat from the second area to the first area to cool the first area.

This configuration allows the heat from the second area to be used to cool the first area efficiently and without waste.

In addition, the building of the present invention may have a first temperature sensor that measures the temperature of the first area and a second temperature sensor that measures the temperature of the second area, and the temperature information of the first area may be the temperature of the first area measured by the first temperature sensor, and the temperature information of the second area may be the temperature of the second area measured by the second temperature sensor.
With this configuration, the temperatures of the first area and the second area can be reliably determined, so that the heat transfer section can be appropriately driven and the temperature of the first area can be maintained at an optimum level.

In the building according to the present invention, the first area may be covered with a heat insulating material.
With this configuration, the first area can be maintained at a comfortable temperature.

According to the present invention, the area to be air-conditioned can be air-conditioned efficiently.

First Embodiment
Hereinafter, a building 1, a building air-conditioning method, and a building air-conditioning system 2 according to an embodiment of the present invention will be described with reference to Figs. 1 to 4.
As shown in Fig. 1, the building 1 according to this embodiment is a two-story house equipped with an air conditioning system 2 according to this embodiment. The building 1 has an LDK 11 (second area), a bathroom 12, and a dressing room 13 (first area) on the first floor, and three rooms 14-16 on the second floor. Rooms and spaces other than those described above, such as an entrance hall, a toilet, a washroom, and a stairwell, are provided as necessary.

The LDK 11 is composed of one room, and the living room, dining room, and kitchen are arranged in one space. The LDK 11 is a space in which an air conditioner 3 or other air conditioner is installed and can be conditioned to a predetermined temperature and humidity. The air conditioner 3 may be capable of conditioning only the temperature or humidity of the air in the LDK 11, or may be capable of conditioning both the temperature and humidity.
The changing room 13 is adjacent to the bathroom 12. The changing room 13 is not equipped with an air conditioner. The changing room 13 is covered with a heat insulating member 18 such as a heat insulating material. The changing room 13 may be a washroom that serves as both a washroom and a changing room.
A corridor 17 is provided between the LDK 11 and the dressing room 13, and travel between the LDK 11 and the dressing room 13 is via the corridor 17.

The three rooms 14-16 on the second floor are separated by walls and are used as bedrooms and children's rooms. Each of the three rooms 14-16 has a window on the south side, and is designed to let in sunlight during the day. The three rooms 14-16 are referred to as the first room 14, the second room 15, and the third room 16. In this embodiment, the first room 14 and the third room 16 are used regularly, and the second room 15 is an empty room that is not used regularly.

The building air conditioning system 2 according to this embodiment is configured to transfer heat from the LDK 11 (second area) to the dressing room 13 (first area) and air-condition the dressing room 13 to a predetermined temperature.
As shown in Figures 1 and 2, the air conditioning system 2 has a heat transfer unit 21 capable of transferring heat from the LDK 11 to the changing room 13, a first temperature sensor 22 that measures the temperature of the changing room 13, a second temperature sensor 23 that measures the temperature of the LDK 11, and a control unit 24 (see Figure 2) that controls the heat transfer unit 21 in accordance with the temperature of the changing room 13 measured by the first temperature sensor 22 and the temperature of the LDK 11 measured by the second temperature sensor 23.

The heat transfer section 21 has a duct 25 (see Figure 1) that connects the changing room 13 and the LDK 11, a fan 26 (blower, see Figure 1) that creates an air flow within the duct 25 from the LDK 11 side to the changing room 13 side, a receiving section 27 (see Figure 2) that receives information from the control section 24, and a driving section 28 (see Figure 2) that drives the fan 26.
1, one end 25a of the duct 25 is connected to an intake port 11a provided on the ceiling of the LDK 11. The other end 25b of the duct 25 is connected to both an upper outlet 13a and a lower outlet 13b provided on the wall of the dressing room 13.
The fan 26 is provided at the intake port 11 a and is configured to draw in air from the LDK 11 and direct it into the duct 25 .
The upper outlet 13a is formed near the upper end of the wall of the changing room 13, and the lower outlet 13b is formed near the lower end of the wall of the changing room 13.
The duct 25 is provided in the ceiling space on the first floor, and in a wall or duct space between the dressing room 13 and the corridor 17, and is configured so as not to be exposed to the interior of the room, such as the living room, the dressing room 13, or the corridor 17.

The upper air outlet 13a and the lower air outlet 13b are each configured to be openable and closable. The heat transfer section 21 is configured to be switchable between three cases: a case in which both the upper air outlet 13a and the lower air outlet 13b are opened to blow air from the LDK 11 to the dressing room 13 from both the upper air outlet 13a and the lower air outlet 13b; a case in which only the lower air outlet 13b is opened to blow air from the LDK 11 to the dressing room 13 from only the lower air outlet 13b; and a case in which only the upper air outlet 13a is opened to blow air from the LDK 11 to the dressing room 13 from only the upper air outlet 13a.

The heat transfer unit 21 is driven by the drive unit 28 based on the information (the rotation speed of the fan 26, the drive time, and the opening/closing information of the upper air outlet 13a and the lower air outlet 13b) received by the receiver 27 from the control unit 24. As a result, either or both of the upper air outlet 13a and the lower air outlet 13b are opened, and the fan 26 is driven.

As shown in FIG. 2, the first temperature sensor 22 has a first temperature detection unit 221 that detects the temperature of the changing room 13 (see FIG. 1), and a first information transmission unit 222 that transmits the temperature of the changing room 13 detected by the first temperature detection unit 221 to the control unit 24. The first temperature sensor 22 is supplied with power from an outlet provided in the changing room 13, and the first information transmission unit 222 may be configured to transmit information (the temperature of the changing room 13) to the control unit 24 wirelessly, or may be configured to transmit information to the control unit 24 via a wired connection such as a USB.

The second temperature sensor 23 has a second temperature detection unit 231 that detects the temperature of the LDK 11, and a second information transmission unit 232 that transmits the temperature of the LDK 11 detected by the second temperature detection unit 231 to the control unit 24. The second temperature sensor 23 may be a temperature sensor of the air conditioner 3 installed in the LDK 11, or may be provided separately from the temperature sensor of the air conditioner 3. When the second temperature sensor 23 is provided separately from the temperature sensor of the air conditioner 3, it may be configured to receive power from an outlet provided in the LDK 11 and the second information transmission unit 232 to transmit information (the temperature of the LDK 11) to the control unit 24 wirelessly, or to transmit information to the control unit 24 via a wire such as a USB.

The control unit 24 has a transmission/reception unit 241 that receives information from the first temperature sensor 22 and the second temperature sensor 23 and transmits information to the heat transfer unit 21, and a calculation unit 242 that calculates the operation of the heat transfer unit 21. The set temperature of the changing room 13 (for example, a desired temperature at which the user feels comfortable) is input to the calculation unit 242. In order to set the changing room 13 to the set temperature, the calculation unit 242 calculates the amount of air to be sent from the LDK 11 to the changing room 13, and calculates the rotation speed and operation time of the fan 26. The calculation unit 242 also determines whether to open either or both of the upper air outlet 13a and the lower air outlet 13b. The rotation speed and operation time of the fan 26 calculated by the calculation unit 242, and the opening and closing information of the upper air outlet 13a and the lower air outlet 13b are transmitted from the transmission/reception unit 241 to the receiving unit 27 of the heat transfer unit 21.

Next, a building air conditioning method according to the present embodiment will be described.
When the temperature of the changing room 13 is lower than that of the LDK 11 and the changing room 13 needs to be heated, the fan 26 of the heat transfer unit 21 is driven to supply air from the LDK 11, which is hotter than the air in the changing room 13, to the changing room 13. This heats the changing room 13. When heating the changing room 13, it is preferable to supply air from the LDK 11 to the changing room 13 from the lower air outlet 13b.

The heating control for heating the changing room 13 to a set temperature will be described with reference to the flow chart shown in FIG.
First, heating control is started (S1-1), and it is determined whether the temperature (T1) of the dressing room 13 measured by the first temperature sensor 22 is lower than a preset temperature (S1-2). If the temperature (T1) of the dressing room 13 measured by the first temperature sensor 22 is lower than the preset temperature, it is determined whether the temperature of the dressing room 13 measured by the first temperature sensor 22 is lower than the temperature (T2) of the LDK 11 measured by the second temperature sensor 23 (S1-3).
If the temperature of the changing room 13 measured by the first temperature sensor 22 is lower than the temperature (T2) of the LDK 11 measured by the second temperature sensor 23, the heat transfer unit 21 is driven to supply air from the LDK 11 to the changing room 13 (S1-4). If the temperature of the changing room 13 measured by the first temperature sensor 22 is equal to or higher than the temperature (T2) of the LDK 11 measured by the second temperature sensor 23, the process returns to the start (S1-1) (S1-8).
After the air from the LDK 11 is supplied to the changing room 13, it is determined whether the temperature (T1) of the changing room 13 has reached the temperature (T2) of the LDK 11 (has risen to the set temperature) (S1-5). If the temperature (T1) of the changing room 13 has reached the temperature (T2) of the LDK 11, the operation of the heat transfer unit 21 is stopped (S1-6) and the process ends (S1-7). If the temperature (T1) of the changing room 13 has not reached the temperature (T2) of the LDK 11, the air from the LDK 11 is supplied to the changing room 13 until the temperature of the changing room 13 reaches the set temperature.

When the temperature of the changing room 13 is higher than the temperature of the LDK 11 and the changing room 13 needs to be cooled, the fan 26 of the heat transfer section 21 is driven to supply the air of the LDK 11, which is cooler than the air in the changing room 13, to the changing room 13. This cools the changing room 13. When cooling the changing room 13, it is preferable to supply the air of the LDK 11 to the changing room 13 from the upper air outlet 13a.

Cooling control when heating the changing room 13 to a set temperature will be described with reference to the flow chart shown in FIG.
First, air conditioning control is started (S2-1), and it is determined whether the temperature of the changing room 13 measured by the first temperature sensor 22 is higher than a preset temperature (S2-2). If the temperature of the changing room 13 measured by the first temperature sensor 22 is higher than the preset temperature, it is determined whether the temperature of the changing room 13 measured by the first temperature sensor 22 is higher than the temperature of the LDK 11 measured by the second temperature sensor 23 (S2-3).
If the temperature of the changing room 13 measured by the first temperature sensor 22 is higher than the temperature of the LDK 11 measured by the second temperature sensor 23, the heat transfer unit 21 is driven (S2-4) and air from the LDK 11 is supplied to the changing room 13. If the temperature of the changing room 13 measured by the first temperature sensor 22 is higher than or equal to the temperature of the LDK 11 measured by the second temperature sensor 23, the process returns to the start (S2-8).
After air from the LDK 11 is supplied to the dressing room 13, it is determined whether the temperature in the dressing room 13 has reached the set temperature (or dropped to the set temperature) (S2-5). If the temperature in the dressing room 13 has reached the set temperature, the operation of the heat transfer unit 21 is stopped (S2-6), and the process ends (S2-7).
If the temperature in the dressing room 13 has not reached the set temperature, air from the LDK 11 is supplied to the dressing room 13 until the temperature in the dressing room 13 reaches the set temperature.

Next, the operation and effects of the building 1, the building air-conditioning method, and the building air-conditioning system 2 according to the embodiment of the present invention described above will be described with reference to the drawings.
In the building 1, the building air conditioning method, and the building air conditioning system 2 according to this embodiment, when air conditioning the dressing room 13 (first area) using heat from the LDK 11 (second area), the heat transfer unit 21 is controlled based on the temperature of the dressing room 13 measured by the first temperature sensor 22 and the temperature of the LDK 11 measured by the second temperature sensor 23, so that the temperature of the dressing room 13 can be set to a desired temperature. The dressing room 13 can be efficiently air-conditioned and maintained at a comfortable temperature.
In addition, the amount of air sent from the LDK 11 to the dressing room 13 can be calculated with high accuracy, and the heat of the LDK 11 can be used to air-condition the dressing room 13 efficiently and without waste.

In the building 1 according to this embodiment, an air conditioner 3 is provided in the living/dining/kitchen area 11 .
This allows the air in the LDK 11 that has been made to a comfortable temperature and humidity by the air conditioner 3 to be transferred to the changing room 13, making it possible to make the temperature and humidity of the changing room 13 comfortable.

In addition, in the building 1 of this embodiment, the heat transfer section 21 has a duct 25 that connects the dressing room 13 and the LDK 11, and a fan 26 that blows air from the LDK 11 to the dressing room 13 via the duct 25.
This allows the air in the LDK 11 to be easily blown into the dressing room 13. Even if an air conditioner cannot be installed in the dressing room 13, the dressing room 13 can be air-conditioned simply by providing an outlet of the duct 25.

In addition, in the building 1 of this embodiment, the heat transfer section 21 has an upper outlet 13a and a lower outlet 13b that blow air from the LDK 11 into the changing room 13, and the upper outlet 13a is located higher than the lower outlet 13b, so that when the temperature of the LDK 11 is higher than the temperature of the changing room 13, the air from the LDK 11 is blown into the changing room 13 from the lower outlet 13b, and when the temperature of the LDK 11 is lower than the temperature of the changing room 13, the air from the LDK 11 is blown into the changing room 13 from the upper outlet 13a.
This allows the air in the LDK 11 to be mixed with the air in the dressing room 13 by utilizing the temperature difference.

In addition, in the building 1 of this embodiment, when the temperature of the changing room 13 measured by the first temperature sensor 22 is lower than a predetermined set temperature and the temperature of the LDK 11 measured by the second temperature sensor 23 is higher than the temperature of the changing room 13 measured by the first temperature sensor 22, the control unit 24 controls the heat transfer unit 21 to transfer heat from the LDK 11 to the changing room 13 to heat the changing room 13.
In addition, in the building 1 of this embodiment, when the temperature of the changing room 13 measured by the first temperature sensor 22 is higher than a predetermined set temperature and the temperature of the LDK 11 measured by the second temperature sensor 23 is lower than the temperature of the changing room 13 measured by the first temperature sensor 22, the control unit 24 controls the heat transfer unit 21 to transfer heat from the LDK 11 to the changing room 13 to cool the changing room 13.
This allows the heat from the LDK 11 to be used to heat and cool the dressing room 13 efficiently and without waste.

In addition, in the building 1 according to this embodiment, the changing room 13 is covered with a heat insulating material 18.
This allows the changing room 13 to be maintained at a comfortable temperature.

Second Embodiment
Next, another embodiment of the present invention will be described based on the attached drawings. The same reference numerals will be used for components and parts that are the same or similar to those of the first embodiment described above, and their description will be omitted. Configurations that differ from the first embodiment will be described.
As shown in FIG. 5, a building 1B, a building air conditioning method, and a building air conditioning system 2B according to the second embodiment have an air conditioning system different from the building air conditioning system 2 of the first embodiment.
In the building air conditioning system 2B according to the second embodiment, the heat transfer section 21B is configured to transfer heat from the second living room 15 (second area) on the second floor, rather than from the LDK 11, to the dressing room 13 (first area) via duct 25B, thereby conditioning the dressing room 13 to a predetermined temperature.
In the air conditioning system 2 according to the second embodiment, a second temperature sensor 23B is provided in the second room 15. One end 25a of the duct 25B is connected to an intake port 15a provided in the ceiling of the second room 15. The other end 25b of the duct 25B is connected to both an upper outlet 13a and a lower outlet 13b provided in the wall of the undressing room 13, as in the first embodiment. A fan 26B is provided in the intake port 15a provided in the ceiling of the second room 15.

The air conditioning system 2 and air conditioning method according to the second embodiment are configured to air condition the dressing room 13 by using heat from the second living room 15 instead of heat from the living/dining/kitchen area 11. The control unit 24 performs the same control as in the first embodiment.

The amount of solar radiation that the second room 15 can obtain through the window is greater than the amount of solar radiation that the changing room 13 can obtain through the window. If the changing room 13 does not have a window, the amount of solar radiation in the changing room 13 is zero.
The second room 15 is a high solar radiation gain area where a large amount of solar radiation can be obtained. The dressing room 13 is a low solar radiation gain area where a small amount of solar radiation can be obtained.
The determination of whether an area is a high solar radiation acquisition area or a low solar radiation acquisition area is based on the relative value of the area ratio of the opening (window) through which sunlight enters, facing either the south, east, west, southeast, or southwest, to the corresponding wall surface. That is, the high solar radiation acquisition area has a higher area ratio of the opening (window) through which sunlight enters, to the corresponding wall surface, than the low solar radiation acquisition area. More specifically, the high solar radiation acquisition area refers to an area that faces either the south, east, west, southeast, or southwest, has an opening (window) through which sunlight enters, and has an area ratio of 30% or more to the wall (exterior wall) facing the outside where the opening is provided. Preferably, it is an area (room, space) on the second floor or higher that has an opening facing approximately south.
A low solar radiation acquisition area is an area (room, space) that has no openings (windows) facing the south, east, west, southeast or southwest, or has only openings facing either the east or west, and the area ratio of the openings to the wall facing the outside (exterior wall) in which the openings are provided is less than 30%.

The building 1, the building air conditioning method, and the building air conditioning system 2 according to the second embodiment provide the same effects as those of the first embodiment.
In addition, in the second embodiment, the second room 15, which is a high solar radiation acquisition area, is assumed to be hotter than the changing room 13, so that when heating the changing room 13, for example in winter, heating can be performed efficiently.

The above describes embodiments of the building 1, the building air conditioning method, and the building air conditioning system 2 according to the present invention. However, the present invention is not limited to the above embodiments and can be modified as appropriate without departing from the spirit of the present invention.
For example, in the above embodiment, the first area to be air-conditioned is the dressing room 13, and the second area that sends heat to the room to be air-conditioned is the living room, dining room, and kitchen 11 or the second living room 15, but the first area and the second area may be rooms or spaces other than those described above. For example, the first area may be a hallway or a toilet. Also, the second area may be an area other than a living room, such as the attic of the building 1.

In the above embodiment, the heat transfer unit 21 has a duct 25 that connects the dressing room 13 and the LDK 11, a fan 26 (air blower) that forms an air flow from the LDK 11 side to the dressing room 13 side in the duct 25, a receiving unit 27 that receives information from the control unit 24, and a driving unit 28 that drives the fan 26, and transfers heat from the LDK 11 (second area) to the dressing room 13 (first area) by blowing air. In contrast, a pipe capable of sending water, hot water, refrigerant, etc. may be provided to connect the first area and the second area, and the heat in the second area may be transferred to the first area via the water, hot water, refrigerant, etc. Also, a heat pipe, a metal rod, a metal pipe, etc. may be provided to connect the first area and the second area, and the heat in the second area may be transferred to the first area via these. Also, the heat in the second area may be transferred to the first area via a steel beam, a column, a metal member, etc. provided in the building.

In the above embodiment, the heat transfer unit 21 has an upper outlet 13a and a lower outlet 13b for blowing air from the second area to the first area, and the upper outlet 13a is provided above the lower outlet 13b. When the temperature of the second area is higher than that of the first area, the air of the LDK 11 is blown from the lower outlet 13b to the first area, and when the temperature of the second area is lower than that of the first area, the air of the second area is blown from the upper outlet 13a to the first area. In contrast, the outlet for blowing air from the second area to the first area may be provided at a desired height (for example, only at a height near the ceiling) or at multiple heights (for example, at a height near the ceiling, a height near the floor, or a height intermediate between the ceiling and the floor).
Furthermore, even if the outlet for blowing air from the second area into the first area is provided only on the upper side of the first area or only on the lower side of the first area, it is possible to equalize the temperature in the first area by adjusting the air volume, wind direction, etc.

In the above embodiment, the heat transfer unit 21 may have a latent heat storage material capable of storing heat in the second area, and may be configured to be able to release the heat of the second area stored in the latent heat storage material to the first area during a desired time period. This configuration makes it possible to have different time periods for storing heat and releasing heat. For example, the heat of the second area that has become hot due to sunlight during the day can be stored in a latent heat storage material, and the heat stored in the latent heat storage material can be released to the first area at night. In addition, the heat of the second area that has been conditioned to a predetermined temperature by operating the air conditioner 3 can be stored in a latent heat storage material, and the heat stored in the latent heat storage material can be released to the first area during a desired time period (for example, a time period when the air conditioner 3 in the first area is not operating).

In the above embodiment, the first temperature sensor 22 is provided to measure the temperature of the first area in order to determine the temperature information of the first area, and the second temperature sensor 23 is provided to measure the temperature of the second area in order to determine the temperature information of the second area. In contrast, the temperature of the first area and the second area may be determined from information such as a weather forecast. Even if the temperature of the first area and the second area is determined from information such as a weather forecast, a sensor for measuring the temperature may be provided in at least one of the first area and the second area, and the temperature of the first area and the second area may be determined taking into account the temperature measured by the sensor. When the temperature of either the first area or the second area is actually measured by the sensor and used, it is preferable to actually measure the first area side, as this makes it easier to provide a comfortable environment that is felt.
In addition, in the above embodiment, the changing room 13 (first area) is covered with the insulating material 18, but it does not have to be covered with the insulating material 18.
