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

Conventionally, hot water panel heaters are known that circulate hot water inside a panel to heat the air inside the panel, and then dissipate the heat inside the panel to heat the air in the space to be heated (see, for example, Patent Document 1).
The hot water type panel heater disclosed in Patent Document 1 has a heat storage section capable of storing heat from the hot water flowing through it. The hot water type panel heater disclosed in Patent Document 1 is configured to be able to heat the air inside the panel with the heat of the heat storage section, or to heat the air in the space to be heated by dissipating the heat of the heat storage section, even when the flow of hot water is stopped. The hot water type panel heater disclosed in Patent Document 1 has a sensor that detects the temperature of the heat storage section, and is controlled so that when the temperature of the heat storage section rises to or above a predetermined first temperature, the flow of hot water in the panel is stopped, and when the temperature of the heat storage section falls to or below a predetermined second temperature, the flow of hot water in the panel is resumed.

When heating, it is necessary to control the temperature of the space to be heated to a comfortable level. For this reason, even if heating is performed based on the temperature of the heat storage unit, the temperature of the space to be heated may not be comfortable, and there is a risk that the heating will not work or that excessive heating will occur.

Therefore, the present invention aims to provide a building, a building air conditioning method, and a building air conditioning system that can maintain a comfortable temperature in the space to be air-conditioned.

In order to achieve the above-mentioned object, a building according to the present invention is a building having an air-conditioned area to be air-conditioned, a heat dissipation means for dissipating heat to the air-conditioned area, and a control unit for controlling the operation of the heat dissipation means, wherein the heat dissipation means has a heat transfer section for transferring heat from another area different from the air-conditioned area, a latent heat storage material provided adjacent to the heat transfer section for storing heat in the heat transfer section, and a heat dissipation section for dissipating the heat stored in the latent heat storage material to the air-conditioned area, wherein the other area is provided in the building, and the control unit controls the operation of the heat dissipation means to heat the air-conditioned area when temperature information of the air-conditioned area is lower than a predetermined set temperature and the temperature of the other area is higher than the temperature information of the air-conditioned area .

Further, the present invention provides an air-conditioning method for a building having an air-conditioned area in a building to be air-conditioned, a heat dissipation means for dissipating heat to the air-conditioned area, and a control unit for controlling the driving of the heat dissipation means, wherein the heat dissipation means has a heat transfer section for transferring heat from outside an area other than the air-conditioned area, a latent heat storage material provided adjacent to the heat transfer section for storing heat in the heat transfer section, and a heat dissipation section for dissipating the heat stored in the latent heat storage material to the air -conditioned area, wherein the other area is provided in the building, and when temperature information of the air-conditioned area is lower than a preset temperature and the temperature of the other area is higher than the temperature information of the air-conditioned area, the heat dissipation means is driven to heat the air-conditioned area.

In addition, the air conditioning system for a building according to the present invention is an air conditioning system for a building having a heat dissipation means for dissipating heat to an air-conditioned area within a building that is to be air-conditioned, and a control unit for controlling the operation of the heat dissipation means, wherein the heat dissipation means has a heat transfer section for transferring heat from another area different from the air-conditioned area, a latent heat storage material provided adjacent to the heat transfer section for storing heat in the heat transfer section, and a heat dissipation section for dissipating the heat stored in the latent heat storage material to the air-conditioned area, the other area being provided in the building, and the control unit controls the operation of the heat dissipation means to heat the air-conditioned area when temperature information of the air-conditioned area is lower than a predetermined set temperature and the temperature of the other area is higher than the temperature information of the air-conditioned area .

In the present invention, the area to be air-conditioned can be efficiently air-conditioned by using the heat stored in the latent heat storage material, and further, the control unit can maintain the area to be air-conditioned at a comfortable temperature by controlling the heat transfer unit based on temperature information of the area to be air-conditioned.
In addition, since the latent heat storage material can store heat for a certain period of time, the control unit can control the time period for storing heat to be different from the time period for releasing heat. For example, heat stored in the latent heat storage material during the day can be released to the changing room at night.
In addition, since the heat dissipation section is configured to dissipate the heat stored in the latent heat storage material to the area to be air-conditioned, it is possible to directly heat or cool the air in the changing room and the people in the changing room, providing comfortable air conditioning.
The phase transition temperature range of the latent heat storage material between melting and solidification is appropriately selected depending on the target temperature of the area to be air-conditioned, the temperature of the heat source supplied to the latent heat storage material, etc. The phase transition temperature may be one level or multiple levels.
"Controlling the operation of the heat dissipation means" means controlling the amount of heat transferred from the heat transfer section to the outside of the area to be air-conditioned, the amount of heat stored in the latent heat storage material (the amount of heat supplied to the latent heat storage material), the amount of heat dissipated from the heat dissipation section, etc.
In addition, in the air conditioning method for a building of the present invention, the heat transfer unit is configured to transfer heat from another area different from the area to be air conditioned, the other area being provided in the building, and when temperature information of the area to be air conditioned is lower than a predetermined set temperature and the temperature of the other area is higher than the temperature information of the area to be air conditioned, the heat dissipation means is driven to heat the area to be air conditioned.
With this configuration, the area to be air-conditioned can be heated efficiently and without wasting energy by utilizing heat from other areas.

In addition, in the building of the present invention, the heat transfer unit may have a heat medium containing heat outside the area to be air-conditioned, and a flow path through which the heat medium flows, the heat of the heat medium being arranged adjacent to the latent heat storage material, and the control unit may be configured to control the amount of the heat medium supplied to the flow path based on temperature information of the area to be air-conditioned.
With this configuration, it is possible to control the amount of heat medium supplied, appropriately control the amount of heat given to the latent heat storage material, and improve the controllability of the temperature in the area to be air-conditioned, thereby optimizing the amount of energy used and improving the comfort of the area to be air-conditioned.

In addition, the building of the present invention may have a temperature sensor that measures the temperature of the area to be air-conditioned, and the temperature information of the area to be air-conditioned may be the temperature of the area to be air-conditioned measured by the temperature sensor.
With this configuration, the temperature of the area to be air-conditioned can be reliably determined, and the supply of heat to the latent heat storage material can be appropriately controlled, for example by determining whether it is necessary and controlling the amount of heat supplied, thereby maintaining the temperature of the area to be air-conditioned at an optimum level and improving the comfort of the area to be air-conditioned.

In the building according to the present invention, the temperature information of the area to be air conditioned may be temperature information that is set according to the season.
With this configuration, it is possible to air-condition the area to be air-conditioned according to the season. Even if it is not possible to install a temperature sensor in the area to be air-conditioned, it is possible to appropriately control the supply of heat to the latent heat storage material by determining whether it is necessary or controlling the amount of supply, thereby maintaining the temperature of the area to be air-conditioned at an optimum level and improving the comfort of the area to be air-conditioned.

In the building according to the present invention, the area to be air-conditioned may be a changing room.
With this configuration, even in a changing room where it is difficult to secure space to install an air conditioner, it is possible to air-condition the room to a comfortable temperature.

In addition, in the building of the present invention, the heat transfer section may be configured to transfer heat of hot water in a bathtub provided in the building.
With this configuration, the heat of the bathtub water can be used to condition the area to be air-conditioned. Compared to using a dedicated hot water supply to condition the area to be air-conditioned, it may be possible to reduce the cost of materials such as water heaters and energy consumption. In addition, since heat can be supplied to the area to be air-conditioned along with the work of boiling water to heat the bathtub water, particularly when the area to be air-conditioned is a place related to bathing, such as a changing room, hot water supply and air conditioning can be performed as a series of bathing actions, resulting in a configuration with excellent convenience and comfort.

In addition, in the building according to the present invention , the other area may be a heat retention area provided in the building where heat of the building is retained.
With this configuration, the heat trapped in the heat trapping area can be used to air condition the area to be air-conditioned, thereby reducing energy consumption.
A hot area is an area located at the top of a building, surrounded by the roof and exterior walls, such as the attic, ceiling space, penthouse, or upper part of a stairwell, which is prone to trapping heat and becoming hotter than the rooms below.

In the building according to the present invention , the other area may be an area provided in the building and air-conditioned by an air conditioner.
With this configuration, the heat of the air in other areas that have been conditioned by the air conditioner can be used to condition the area to be conditioned, thereby reducing energy consumption.
Basically, the air conditioned by the air conditioner is kept at a comfortable temperature that is maintained (set) by the latent heat storage material, so the temperature in the area to be air conditioned can be made comfortable.

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

In addition, in the building according to the present invention, the heat dissipation means may be formed in a panel shape, one surface of which is provided facing the area to be air-conditioned, and the heat dissipation section may be provided on the one surface.
With this configuration, heat can be efficiently dissipated from a wide range to the area to be air-conditioned.

In addition, in the building according to the present invention, the heat dissipation means may be formed long and provided along the area to be air-conditioned, with the heat dissipation section being provided in a portion facing the area to be air-conditioned.
With this configuration, heat can be efficiently dissipated from a wide range to the area to be air-conditioned.

In addition, in the air conditioning method for a building of the present invention , when temperature information of the area to be air-conditioned is higher than a predetermined set temperature and the temperature of the other area is lower than the temperature information of the area to be air-conditioned, the heat dissipation means may be driven to cool the area to be air-conditioned.
With this configuration, the heat from other areas can be used to cool the area to be air-conditioned efficiently and without wasting energy.

According to the present invention, the space to be air-conditioned can be maintained at a comfortable temperature.

First Embodiment
Hereinafter, a building, a building air-conditioning method, and a building air-conditioning system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.
As shown in Fig. 1, a 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, a bathroom 12, and a dressing room 13 (areas to be air-conditioned) on the first floor, and three rooms 14-16 on the second floor. Rooms and spaces other than those mentioned above, such as an entrance hall, a toilet, a washroom, and a stairwell, are provided as necessary.

The LDK 11 is made up of one room, and includes a living room, a dining room, and a kitchen. The LDK 11 is a space in which an air conditioner 41 or other air conditioner is installed and which can be conditioned to a predetermined temperature.
The dressing room 13 is adjacent to the bathroom 12. The dressing room 13 is not equipped with an air conditioner. The dressing room 13 is covered with a heat insulating member 18 such as a heat insulating material. The dressing room 13 may be a washroom that serves as both a washroom and a dressing 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 windows on the south side, and is designed to let in sunlight during the day. An attic 19 is provided above the second floor rooms 14-16 and the hallway. Insulation is provided between the second floor rooms 14-16, the hallway, etc. and the attic 19, so that heat from the attic 19 is not easily transferred to the second floor rooms 14-16 and the hallway.

The building air conditioning system 2 according to this embodiment is configured to use the hot water 27 (hot water) in the bathtub 121 of the bathroom 12 as a heat medium to condition the dressing room 13 to a predetermined temperature. The building 1 is provided with a water heater 3 that supplies hot water to each facility provided in the house. The water heater 3 is configured to be able to supply hot water to the bathtub 121 via the bathtub piping 31, and is also configured to be able to supply the hot water 27 in the bathtub 121 to the building air conditioning system 2. The water heater 3 is installed outdoors.

The building air conditioning system 2 in this embodiment has a heat dissipation means 21 that dissipates heat into the changing room 13, a first temperature sensor 22 that detects the temperature of the changing room 13, and a control unit 23 (see Figure 2) that controls the heat dissipation means 21 depending on the temperature of the changing room 13 determined by the first temperature sensor 22.
The heat dissipation means 21 includes a heat transfer section 28 that circulates the hot water 27 in the bathtub 121 to transfer the heat of the hot water 27, a latent heat storage material 262 that is provided adjacent to the heat transfer section 28 and stores the heat transferred by the heat transfer section 28, a heat dissipation section 263 that radiates the heat stored in the latent heat storage material 262 to the changing room 13, a receiving section 211 (see Figure 2) that receives information from the control section 23, and a driving section 212 (see Figure 2) that drives the circulation of the hot water 27.
The heat transfer section 28 has hot water 27 (heat medium) and a flow path 29 through which the heat medium flows.

In this embodiment, the heat dissipation means 21 has a radiation panel 26 and a hot water pipe 25 connected to the radiation panel 26 and the water heater 3. The latent heat storage material 262 and the heat dissipation section 263 are provided in the radiation panel 26. The flow path 29 of the heat transfer section 28 is provided in the radiation panel 26 and the hot water pipe 25.
As shown in Figures 1 and 3, the radiation panel 26 is formed in a panel shape. A radiation panel internal flow path 261 through which the hot water 27 flows, and a latent heat storage material 262 are provided inside the radiation panel 26. The latent heat storage material 262 is adjacent to the radiation panel internal flow path 261. A heat dissipation section 263 is provided on one surface of the radiation panel 26. The heat dissipation section 263 is provided over almost the entire one surface of the radiation panel 26. As shown in Figure 1, the radiation panel 26 is provided on the ceiling of the changing room 13, and the one surface on which the heat dissipation section 263 is provided becomes the lower surface and faces the changing room 13.

The hot water pipe 25 has a hot water feed pipe 251 that sends hot water 27 from the water heater 3 to the radiation panel 26, and a hot water return pipe 252 that returns the hot water 27 that has flowed through the flow path 29 of the radiation panel 26 to the water heater 3. The hot water feed pipe 251 is connected to the upstream end 261a (see FIG. 3) of the flow path 261 inside the radiation panel, and the hot water return pipe 252 is connected to the downstream end 261b of the flow path 261 inside the radiation panel. The hot water pipe 25 and the flow path 261 inside the radiation panel correspond to the flow path 29 of the heat transfer section 28.

As shown in Fig. 3, the radiation panel 26 may be provided with a hose that serves as a radiation panel internal flow path 261, and a latent heat storage material 262 may be provided around this hose. Also, as shown in Fig. 4, the radiation panel 26 may be provided with a plurality of block-shaped latent heat storage materials 262 spaced apart from one another, and the spaces between adjacent latent heat storage materials 262 may serve as radiation panel internal flow paths 261 through which hot water 27 can flow. The block-shaped latent heat storage material 262 may be produced, for example, by housing the latent heat storage material in a bag.
The melting/solidifying phase transition temperature range of the latent heat storage material 262 is appropriately selected depending on the target temperature of the area to be air-conditioned (the changing room 13) and the temperature of the heat source supplied to the latent heat storage material 262. In addition, the phase transition temperature may be at one level or at multiple levels.

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 23. 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 23 wirelessly, or may be configured to transmit information to the control unit 23 via a wired connection such as a USB.

The control unit 23 has a transceiver unit 231 that receives information from the first temperature sensor 22 and transmits information to the heat dissipation means 21, and a calculation unit 232 that calculates the drive of the heat dissipation means 21. The set temperature of the changing room 13 (e.g., a desired temperature at which the user feels comfortable) is input to the calculation unit 232. The calculation unit 232 calculates the amount of hot water 27 (water volume) to circulate through the heat dissipation means 21 to set the changing room 13 to the set temperature. The calculated water volume is transmitted from the transceiver unit 231 to the receiver unit 211 of the heat dissipation means 21.
In the control unit 23 , the transmitting/receiving unit 231 also receives information such as the temperature of the hot water 27 and the amount of hot water 27 flowing into the radiation panel 26 , and the calculation unit 232 calculates the drive of the heat dissipation means 21 using this information as well.

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 the set temperature and the changing room 13 is to be heated, the heat dissipation means 21 is driven to circulate hot water 27 from the water heater 3 to the flow path 29. This causes the heat of the hot water 27 to be stored in the latent heat storage material 262 of the radiation panel 26. The stored heat is then dissipated from the heat dissipation section 263 to the changing room 13, heating the changing room 13.

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 (S-1), and it is determined whether the temperature (T1) of the changing room 13 measured by the first temperature sensor 22 is lower than a preset temperature (S-2). If the temperature (T1) of the changing room 13 measured by the first temperature sensor 22 is lower than the preset temperature, the heat dissipation means 21 is driven to circulate the hot water 27 through the flow path 29, the heat of the hot water 27 is stored in the latent heat storage material 262, and the heat stored in the latent heat storage material 262 is dissipated to the changing room 13 (S-3).
When the temperature (T1) of the changing room 13 reaches the set temperature, the operation of the heat dissipation means 21 is stopped and the process ends (S-4). When the temperature (T1) of the changing room 13 has not reached the set temperature, the hot water 27 is circulated through the flow path 29 until the temperature of the changing room 13 reaches the set temperature, and the heat stored in the latent heat storage material 262 is dissipated to the changing room 13.

In this embodiment, the water heater 3 can be switched between a mode of supplying hot water 27 to the facilities of the building 1 and a mode of circulating the hot water 27 in the bathtub 121 to the flow path 29 of the heat dissipation means 21, and can execute both modes simultaneously. Therefore, for example, if a hot water floor heating facility is installed in the changing room 13, the supply of hot water 27 to the floor heating facility and the circulation of the hot water 27 in the bathtub 121 to the heat dissipation means 21 can be performed simultaneously. In other words, heating by the floor heating facility in the changing room 13 and heating by the building's air conditioning system 2 can be performed simultaneously.

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, the changing room 13 (air-conditioned area) can be efficiently air-conditioned by using the heat stored in the latent heat storage material 262, and further, the changing room 13 can be maintained at a comfortable temperature by the control unit 23 controlling the heat transfer unit 28 based on the temperature of the changing room 13.
Since the latent heat storage material 262 can store heat for a certain period of time, the control unit 23 can control the time period for storing heat to be different from the time period for releasing heat. For example, heat stored in the latent heat storage material 262 during the day can be released to the changing room 13 at night.

In addition, in this embodiment, the heat transfer section 28 is configured to transfer the heat of the water in a bathtub provided in the building 1.
With this configuration, the heat of the bathtub water can be used to air-condition the changing room 13. In some cases, it is possible to reduce the cost of materials such as water heaters and reduce energy consumption compared to using a dedicated hot water supply to air-condition the changing room 13. In addition, since heat can be supplied to the changing room 13, which is related to bathing, in addition to the water heating operation to heat the bathtub water, hot water supply and air conditioning of the changing room 13 can be performed as a series of bathing operations, resulting in a configuration that is highly convenient and comfortable.

In addition, in this embodiment, the air in the changing room 13 and the people in the changing room 13 can be directly heated by the radiant heat from the radiation panel 26, thereby providing comfortable heating.
In addition, in this embodiment, air conditioning can be performed even in the changing room 13 where there is no space available to install an air conditioning device.

In addition, in this embodiment, the heat transfer section 28 has a heat medium (hot water 27) and a flow path 29 through which the heat medium flows, and the heat of the heat medium is stored in the latent heat storage material 262, and the control section controls the amount of heat medium supplied to the flow path 29.
With this configuration, it is possible to control the amount of heat medium supplied, appropriately control the amount of heat given to the latent heat storage material 262, and improve the controllability of the temperature in the changing room 13. As a result, it is possible to optimize the amount of energy used and improve the comfort of the changing room 13.

In this embodiment, a first temperature sensor 22 is provided in the changing room 13, and air conditioning of the changing room 13 is performed based on the temperature measured by the first temperature sensor 22.
With this configuration, the temperature of the changing room 13 can be reliably determined, and the supply of heat to the latent heat storage material 262 can be appropriately controlled, for example, by determining whether it is necessary and controlling the amount of heat supplied, thereby maintaining the temperature of the changing room 13 at an optimum level and improving the comfort of the changing room 13.

In addition, in this embodiment, the changing room 13 is covered with insulating materials, so that the air-conditioned changing room can be maintained at a comfortable temperature.

In this embodiment, the heat dissipation section 263 is formed on one side of the radiation panel 26 which is formed in a panel shape, and is positioned so as to face the changing room 13.
With this configuration, the heat stored in the latent heat storage material 262 can be efficiently dissipated to the changing room 13 from a wide area.
Although the heat transfer unit 28 has been described in an embodiment in which it transfers the heat of the bathtub water provided in the building 1, it is not limited to this and may also use a heat source machine having two systems for bath hot water supply and floor heating.
