Description

The present invention relates to an air conditioner and a valve.

It has four ports formed at equal intervals with respect to a member having a circular cross section, and forms a first flow path in which adjacent first port and second port communicate with each other, and adjacent third port and third port. A 4-port valve having a second flow path communicating with the 4-port has been proposed (see, for example, Patent Documents 1 to 3). According to this 4-port valve, the connection destination of each port can be changed to change the flow path by adjusting the rotation angle.

However, the 4-port valves described in Patent Documents 1 to 3 only switch the flow path, and even if they are applied to an air conditioner, the extent to which they can contribute to the miniaturization of the device is not high.

The present invention has been made to solve such a problem, and an object of the present invention is to provide an air conditioner and a valve capable of further miniaturization.

The present invention forms a first flow path in which the adjacent first port and the second port communicate with each other, and forms a second flow path in which the adjacent third port and the fourth port communicate with each other. A valve having a desiccant element is provided in each of the two flow paths, and the rotation is controlled.

According to the present invention, since each of the first and second flow paths is provided with a valve having a desiccant element, by controlling the rotation of the valve, not only the function of switching the flow path but also the desiccant element is in a dry state. It can dehumidify the gas that sometimes passes, or humidify the gas that passes when the desiccant element is in a wet state. As a result, for example, it is not necessary to separately provide a desiccant member, and even if a desiccant member is provided, the desiccant member can be made smaller, so that the size can be further reduced.

Hereinafter, the present invention will be described with reference to preferred embodiments. The present invention is not limited to the embodiments shown below, and can be appropriately modified without departing from the spirit of the present invention. Further, in the embodiments shown below, some parts of the configuration are omitted from the illustration and description, but the details of the omitted technology are within a range that does not cause any contradiction with the contents described below. Needless to say, publicly known or well-known techniques are applied as appropriate.

FIG. 1 is a schematic configuration diagram showing an air conditioner according to the first embodiment of the present invention. The air conditioner 1 shown in FIG. 1 roughly includes a solar heat receiving unit 10, a central unit 20, an upper unit 30, a lower unit 40, and a control device (control means) CD.

FIG. 2 is a schematic configuration diagram showing the solar heat receiving unit 10 shown in FIG. The solar heat receiving unit 10 shown in FIG. 2 is an energy collecting panel for receiving solar heat, and includes a surface panel 11, a plurality of vacuum tube collectors 12, and a reflecting member 13.

The surface panel 11 is a transparent glass material or resin material formed in a flat plate shape that allows sunlight Ray to pass through.

The plurality of vacuum tube collectors 12 include an outer tube for forming a vacuum and an inner tube inserted into the outer tube. The inner tube is subjected to selective absorption treatment on its surface, and receives sunlight Ray that has passed through the surface panel 11 to heat the heat medium or the like inside the tube. Such vacuum tube collectors 12 are arranged at predetermined intervals in the vertical direction.

The reflective member 13 is a member that reflects sunlight Ray that has passed between the vacuum tube collectors 12, and is configured by providing an infrared reflective film on the surface of the surface panel 11 side. Further, the surface is serrated in cross section. The saw blade is set at an angle so that the sunlight Ray that has passed between the vacuum tube collectors 12 is reflected by either the upper or lower vacuum tube collector 12. By setting such an angle, the vacuum tube collector 12 can efficiently heat the heat medium.

In this embodiment, since the solar heat receiving unit 10 is used for the window surface, the reflecting member 13 transmits, for example, a predetermined amount (specifically, 20% or more and less than 40% (particularly 30%)) of visible light, and the rest is transmitted. Those that reflect are preferable. This is because if visible light is transmitted by 20% or more, visibility of an external landscape or the like can be ensured to some extent when used as a window surface. Further, it is preferable that infrared rays are reflected by 90% or more. By using such a reflective member 13, about 70% of visible light, which occupies about 52% of the energy of sunlight, and 90% or more of infrared rays, which occupy about 42% of energy, are reflected, which is a total. This is because it is possible to prevent a large decrease in the visibility of the outside scenery while allowing 74% or more of the energy to reach the vacuum tube collector 12.

FIG. 3 is a schematic configuration diagram showing the central unit 20 shown in FIG. As shown in FIG. 3, the central unit 20 is an air-conditioning structure (air-conditioning) including two plate members 21 and 22, peripheral end members 23, a plurality of intervening members 24, a refrigerant distributor 25, and an absorbent liquid distributor 26.

The first intervening member 24a is provided on the upper side between the two plate members 21 and 22. In the present embodiment, the space sandwiched between the upper peripheral end member 23 and the first intervening member 24a utilizes the heat (heated heat medium) received by the solar heat receiving unit 10 to absorb liquid (for example, bromide). It functions as a regenerator R that heats a dilute solution in which a lithium aqueous solution) and a refrigerant (for example, water) are mixed. The regenerator R evaporates the refrigerant from the dilute solution by the above heating and separates the dilute solution into the refrigerant vapor and the concentrated solution.

The second intervening member 24b is provided at the lower part of the first intervening member 24a among the two plate members 21 and 22. In the present embodiment, the space sandwiched between the first intervening member 24a and the second intervening member 24b functions as a condenser C for liquefying the steam refrigerant generated by the regenerator R. It is preferable that the heat of vaporization is discharged to the outdoor side through the second plate material (outdoor plate material) 22 side.

The plurality of third intervening members 24c are provided at substantially equal intervals on the lower side of the second intervening member 24b among the two plate members 21 and 22. In the present embodiment, the space (lower space of the condenser C) sandwiched between the second intervening member 24b and the lower peripheral end member 23 is in a depressurized state. That is, the plurality of third intervening members 24c function as members that support the two plate members 21 and 22 from the inside so as to be able to withstand the reduced pressure state.

Further, the lower space of the condenser C functions as an evaporator E and an absorber A. More specifically, on the side of the first plate material (indoor side plate material) 21 of this lower space, a refrigerant distributor 25 for dropping the liquid refrigerant obtained by the condenser C onto the inner wall of the first plate material 21 is provided. .. When the refrigerant is dropped by the refrigerant distributor 25, the refrigerant evaporates on the first plate 21 side to become a steam refrigerant. As a result, the first plate material 21 side of the lower space functions as an evaporator E for cooling the first plate material 21.

Further, on the side of the second plate material 22 of this lower space, an absorbent liquid distributor 26 for dropping the concentrated solution obtained by the regenerator R onto the inner wall of the second plate material 22 is provided. When the concentrated solution is dropped by the absorbent liquid distributor 26, the concentrated solution absorbs the vapor refrigerant from the evaporator E. As a result, the second plate material 22 side of the lower space functions as an absorber A that heats the second plate material 22 by the absorbed heat.

As described above, the air-conditioning structure ACS including the two plate members 21 and 22, the peripheral end member 23, the plurality of intervening members 24, the refrigerant distributor 25, and the absorbent liquid distributor 26 has two sheets. Of the plate materials 21 and 22, the first plate material 21 on the indoor side is cooled and the second plate material 22 on the outdoor side is heated.

The central unit 20 has a pump (not shown), and the pump power is used to send a dilute solution that has absorbed the vapor refrigerant to the regenerator R.

It is a thing. The indoor flow path forming plate material 27 is arranged adjacent to the first plate material 21 with a predetermined gap, so that the gap between the first plate material 21 and the indoor flow path forming plate material 27 can be created as an indoor flow path. Make it function as an IP. In particular, when the air-conditioning structure ACS is driven, the first plate material 21 is cooled, so that the indoor flow path IP becomes a flow path through which the cooled air flows.

Further, the reflective member (outdoor flow path forming plate material) 13 of the solar heat receiving unit 10 is adjacently arranged with a predetermined gap so as to be substantially parallel to the second plate material 22 of the air conditioning structure ACS. The reflective member 13 is arranged adjacent to the second plate material 22 of the air conditioning structure ACS with a predetermined gap, so that the gap between the second plate material 22 and the reflective member 13 is used as an outdoor flow path OP. Make it work. In particular, when the air-conditioning structure ACS is driven, the second plate material 22 is heated, so that the outdoor flow path OP becomes a flow path through which the heated air flows.

In this underfloor space UFC, a plurality of trays T, a plurality of bag-shaped containers B, and a plurality of pedestal PDs are arranged.

The plurality of trays T are for mounting the bag-shaped container B in which the latent heat storage material PCM is stored, and are mounted on the floor slab FS in the present embodiment. Such a tray T receives the latent heat storage material PCM leaked when the bag-shaped container B is damaged, and also receives the dew condensation water when the surrounding air is cooled below the dew point and dew condensation occurs.

See FIG. 1 again. The control device CD shown in FIG. 1 controls the entire air conditioner 1, and controls the rotation of the upper valve 34 and the lower valve 44, the upper fan F1 and the lower fan shown in each of the above figures. Drive control of F2, opening / closing control of louvers 32, 33, 42, 43, drive control of air conditioning structure ACS, opening and closing control of valves 36, 37, 46, and lower unit 40 and floor space and floor space UFC. It executes connection switching control with. The control device CD can execute the first to eighth operation modes by controlling these by the user's designation of the operation mode and automatic control.

Next, the operation of the air conditioner 1 according to the present embodiment in each operation mode will be described with reference to FIGS. 9 to 15.

FIG. 9 is an operating state diagram of the air conditioner 1 in the first operation mode. In the first operation mode, the control device CD uses the heat received by the solar heat receiving unit 10 to perform regeneration in the regenerator R, and also causes the condenser C, the evaporator E, and the absorber A to function. The 1st plate 21 side is cooled and the 2nd plate 22 side is heated. Further, the control device CD opens all the louvers 32, 33, 42, 43 and puts the upper side and lower side fans F1 and F2 into the driving state. The valves 36, 37, and 46 are closed.

In this state, the control device CD rotates the upper valve 34 at first predetermined time (for example, 180 seconds) intervals, and switches the upper valve 34 between the first state and the second state every first predetermined time. Further, the control device CD rotates the lower valve 44 at a second predetermined time (for example, 180 seconds) interval, and switches the lower valve 44 between the first state and the second state every second predetermined time.

As a result, the indoor air is dehumidified by the desiccant element D of the first flow path 34a of the upper valve 34, then cooled by the indoor flow path IP, and further cooled by the desiccant element D of the first flow path 44a of the lower valve 44. It is dehumidified and returned to the room again. On the other hand, the outside air is heated by the outdoor flow path OP after regenerating the desiccant element D of the second flow path 44b of the lower valve 44, regenerates the desiccant element D of the second flow path 34b of the upper valve 34, and again. Returned to the outside of the room. Then, the first flow paths 34a and 44a and the second flow paths 34b and 44b are replaced by rotation, and the above is continuously performed. Therefore, in the first operation mode, the indoor air is continuously cooled and dried.

The first operation mode is provided with a saving mode, and the air conditioner 1 can also be operated in the saving mode. In the saving mode, the control device CD opens the upper outdoor valve 36 and the lower outdoor valve 46.

As a result, when the wind can be used when the outside air is taken in, the outside air can be directly introduced into the outdoor flow path OP and discharged without going through the upper valve 34 and the lower valve 44, and the desiccant element D can be slightly regenerated. Although the capacity is weakened, the power of the lower fan F2 when air is passed through the outdoor flow path OP can be saved.

FIG. 10 is an operating state diagram of the air conditioner 1 in the second operation mode (fourth operation mode). In the second operation mode, the control device CD operates the regenerator R, the condenser C, the evaporator E, and the absorber A to cool the first plate material 21 side and heat the second plate material 22 side. Further, the control device CD opens all the louvers 32, 33, 42, 43, drives the upper and lower fans F1 and F2, and closes the valves 36, 37, 46.

In this state, the control device CD rotates the upper valve 34 at a third predetermined time (for example, 180 seconds) interval, and switches the upper valve 34 between the first state and the second state every third predetermined time. Further, the control device CD rotates the lower valve 44 at a fourth predetermined time (for example, 60 seconds) interval, and switches the lower valve 44 between the third state and the fourth state every fourth predetermined time.

As a result, for example, the indoor air is dehumidified by the desiccant element D of the first flow path 34a of the upper valve 34 and then cooled by the indoor flow path IP to form the desiccant element D of the second flow path 44b of the lower valve 44. It is regenerated and heated by the outdoor flow path OP to regenerate the desiccant element D of the second flow path 34b of the upper valve 34 and is discharged to the outside. On the other hand, the outside air is totally heat exchanged at the lower valve 44 and introduced into the room. That is, the outside air is dehumidified by the desiccant element D of the first flow path 44a of the lower valve 44 and introduced into the room, and the lower valve 44 has a certain heat capacity and is cooled by the second flow path 44b. Therefore, the air introduced into the room is cooled through the first flow path 44a. Then, the first flow paths 34a and 44a and the second flow paths 34b and 44b are replaced by rotation, and the above is continuously performed. Therefore, in the second operation mode, the outside air is continuously exchanged (cooled and dried) and introduced while ventilating.

FIG. 11 is an operating state diagram of the air conditioner 1 in the third operation mode. In the third operation mode, the control device CD does not function the regenerator R, the condenser C, the evaporator E and the absorber A, opens all the louvers 32, 33, 42, 43 and opens the upper and lower fans. F1 and F2 are set to the driving state, and the valves 36, 37, and 46 are set to the closed state.

In this state, the control device CD rotates the upper valve 34 at a fifth predetermined time (for example, 60 seconds) interval, and switches the upper valve 34 between the third state and the fourth state every fifth predetermined time. Further, the controller CD maintains the lower valve 44 in either the first or second state.

As a result, for example, when the outside air temperature is higher than room temperature and the indoor air has a lower humidity than the outside air, the indoor air is discharged to the outside after regenerating the desiccant element D of the first flow path 34a of the upper valve 34. On the other hand, the outside air is totally heat exchanged at the upper valve 34 and introduced into the room. That is, the outside air flows from the lower valve 44 through the outdoor flow path OP, is dehumidified by the desiccant element D of the second flow path 34b of the upper valve 34, then flows through the indoor flow path IP, and is introduced into the room through the lower valve 44. Will be done. Further, since the upper valve 34 has a certain heat capacity and indoor air lower than the outside air temperature flows through the second flow path 34b, the air introduced into the room is cooled through the first flow path 34a. Then, the first flow path 34a and the second flow path 34b of the upper valve 34 are replaced by rotation, and the above is continuously performed. Therefore, in the third operation mode, the outside air is continuously exchanged (cooled and dried) and introduced while ventilating.

See FIG. In the fourth operation mode shown in FIG. 10, the control device CD does not function the regenerator R, the condenser C, the evaporator E, and the absorber A, opens all the louvers 32, 33, 42, 43, and opens the upper side. The lower fans F1 and F2 are set to the driving state, and the valves 36, 37, and 46 are set to the closed state.

In this state, the controller CD maintains the upper valve 34 in either the first or second state. Further, the control device CD rotates the lower valve 44 at intervals of a sixth predetermined time (for example, 60 seconds), and switches the upper valve 34 between the third state and the fourth state every sixth predetermined time.

As a result, for example, when the outside air temperature is higher than room temperature and the indoor air is lower in humidity than the outside air, the indoor air flows from the upper valve 34 to the indoor flow path IP and the desiccant element of the second flow path 44b of the lower valve 44. After regenerating D, it flows through the outdoor flow path OP and is discharged to the outside through the upper valve 34. On the other hand, the outside air is totally heat exchanged at the lower valve 44 and introduced into the room. That is, the outside air is introduced into the room after being dehumidified by the desiccant element D of the first flow path 44a of the lower valve 44. Further, since the lower valve 44 has a certain amount of heat capacity and indoor air lower than the outside air temperature flows through the second flow path 44b, the air introduced into the room is cooled through the first flow path 44a. Then, the first flow path 44a and the second flow path 44b of the lower valve 44 are replaced by rotation, and the above is continuously performed. Therefore, it is possible to continuously exchange the outside air (cooling and drying) and introduce the outside air while ventilating.

FIG. 12 is an operating state diagram of the air conditioner 1 in the fifth operation mode. In the fifth operation mode, the indoor side of the lower unit 40 is the underfloor space UFC. Further, in FIG. 12, the illustration of the control device CD is omitted.

In the fifth operation mode, the control device CD does not function the regenerator R, the condenser C, the evaporator E and the absorber A, and opens the louvers 33, 42, 43. The louver 32 is closed. Further, in the control device CD, the upper side and lower side fans F1 and F2 are in the driving state, and the valves 36 and 46 are in the closed state.

In this state, when introducing outside air into the underfloor space UFC, the control device CD drives the lower fan F2 and connects the lower fan F2 and the underfloor space UFC to the first flow path 44a or the second flow of the lower valve 44. Connect by road 44b. On the other hand, when the control device CD exhausts from the underfloor space UFC, the upper fan F1 is driven and the upper indoor valve 37 is opened, and the indoor flow path IP and the underfloor space UFC are connected to the lower valve 44. Connect with the first flow path 44a or the second flow path 44b, and connect the upper fan F1 and the upper outdoor space UCO (outdoor) with the first flow path 34a or the second flow path 34b of the upper valve 34. .. Then, the control device CD switches this every predetermined time (for example, 180 seconds).

As a result, in the fifth operation mode, for example, exhaust from the underfloor space UFC and intake air to the underfloor space UFC can be alternately performed by time allocation.

FIG. 13 is an operating state diagram of the air conditioner 1 in the sixth operation mode. In the sixth operation mode, the indoor side of the lower unit 40 is the underfloor space UFC. In the sixth operation mode, the control device CD does not function the regenerator R, the condenser C, the evaporator E and the absorber A, and opens all the louvers 32, 33, 42, 43. Further, in the control device CD, the upper side and lower side fans F1 and F2 are in the driving state, and the valves 36, 37 and 46 are in the closed state.

In this state, the control device CD drives the lower fan F2, connects the lower fan F2 and the underfloor space UFC with the first flow path 44a or the second flow path 44b of the lower valve 44, and connects the lower side fan F2 with the second flow path 44b. While driving F1, the upper fan F1 and the upper outdoor space UCO (outdoor) are connected by the first flow path 34a or the second flow path 34b of the upper valve 34.

As a result, in the sixth operation mode, the lower unit 40 can introduce the outside air into the underfloor space UFC, while the upper unit 30 can discharge the indoor air.

FIG. 14 is an operating state diagram of the air conditioner 1 in the seventh operation mode. In the seventh operation mode, the indoor side of the lower unit 40 is the underfloor space UFC. Further, in FIG. 14, the illustration of the control device CD is omitted.

In the seventh operation mode, the control device CD does not function the regenerator R, the condenser C, the evaporator E and the absorber A, and opens all the louvers 32, 33, 42, 43. Further, in the control device CD, the upper side and lower side fans F1 and F2 are in the driving state, and the valves 36, 37 and 46 are in the closed state.

In this state, when the outside air is introduced into the room, the control device CD drives the lower fan F2 and connects the lower fan F2 and the indoor flow path IP with the third flow path 44c of the lower valve 44. The upper fan F1 and the indoor flow path IP are connected by the first flow path 34a or the second flow path 34b of the upper valve 34. On the other hand, when exhausting from the room, the control device CD drives the upper fan F1 and connects the upper fan F1 and the upper outdoor space UCO (outdoor) to the first flow path 34a or the first flow path 34a of the upper valve 34. Two channels are connected by 34b. Then, the control device CD switches this every predetermined time (for example, 180 seconds).

As a result, in the seventh operation mode, for example, exhaust from the room and intake into the room can be alternately performed by time allocation.

Here, in the seventh operation mode, when the outside air is introduced into the room, it is preferable to open the upper indoor valve 37. As a result, when introducing the outside air, the outside air can be introduced not only by the first flow path 34a or the second flow path 34b of the upper side valve 34 but also by the flow path released by the upper side indoor valve 37, and the outside air introduction resistance is reduced. This is because it can be reduced and contribute to the smooth introduction of outside air. When exhausting from the room, the upper indoor valve 37 is closed.

FIG. 15 is an operating state diagram of the air conditioner 1 in the eighth operation mode. In the eighth operation mode, the indoor side of the lower unit 40 is the underfloor space UFC. In the eighth operation mode, the control device CD does not function the regenerator R, the condenser C, the evaporator E and the absorber A, and opens all the louvers 32, 33, 42, 43. Further, in the control device CD, the upper side and lower side fans F1 and F2 are in the driving state, and the valves 36, 37 and 46 are in the closed state.

In this state, the control device CD drives the upper fan F1 and connects the upper fan F1 and the indoor flow path IP by the first flow path 34a or the second flow path 34b of the upper valve 34, and indoors. The flow path IP and the underfloor space UFC are connected by the first flow path 44a or the second flow path 44b of the lower valve 44.

As a result, indoor air can be sent to the underfloor space UFC, cooled or heated by the latent heat storage material PCM in the underfloor space UFC, and returned to the floor space, and the comfort of the floor space using the latent heat storage material PCM can be circulated inside the air. Can be done by.

The above is the first to eighth operation modes.

Here, among the above operation modes, it is preferable to refer to the carbon dioxide concentration for switching between the first operation mode and the second operation mode. That is, it is assumed that the user is using the air conditioner 1 in the summer and the control device CD is operated in the first operation mode. When the gas sensor (not shown) detects that the carbon dioxide concentration exceeds a predetermined value, the control device CD operates the air conditioner 1 in the second operation mode. This is because it is possible to bring about a cooling effect in the room while ventilating.

In this way, according to the air conditioner 1 according to the first embodiment, the valves 34, 44 having the desiccant element D are provided in each of the first and second flow paths 34a, 34b, 44a, 44b. By controlling the rotation, not only the function of switching the flow path, but also the gas passing when the desiccant element D is in a dry state is dehumidified, and the gas passing when the desiccant element D is in a wet state is humidified. You can do it. As a result, it is not necessary to separately provide a desiccant member, and the desiccant member to be provided can be made smaller, so that the size can be further reduced.

Further, in order to include the air conditioning structure ACS, the upper valve 34 on the upper side thereof, and the lower valve 44 on the lower side thereof, the upper valve 34 and the lower valve 44 are rotated to provide an indoor flow. The road IP and the outdoor flow path OP can be connected, and the air cooled or heated in the first and second flow paths 34a, 34b, 44a, 44b of the upper valve 34 and the lower valve 44 can be connected. It is possible to provide an air conditioner 1 which can be distributed and can perform not only humidity control but also temperature control.

Further, since the upper valve 34 and the lower valve 44 are switched between the first state and the second state in the first operation mode, the indoor air is dehumidified by the desiccant element D of the first flow path 34a of the upper valve 34. After that, it is cooled by the indoor flow path IP, further dehumidified by the desiccant element D of the first flow path 44a of the lower valve 44, and returned to the room again. On the other hand, the outside air is heated by the outdoor flow path OP after regenerating the desiccant element D of the second flow path 44b of the lower valve 44, regenerates the desiccant element D of the second flow path 34b of the upper valve 34, and again. Returned to the outside of the room. Then, the first flow paths 34a and 44a and the second flow paths 34b and 44b are replaced by rotation, and the above is continuously performed. Therefore, the indoor air can be continuously cooled and dried.

Further, in order to open both the upper outdoor valve 36 and the lower outdoor valve 46 in the saving mode, if the wind can be used when inhaling the outside air, the upper valve 34 and the lower valve 44 should be used. Instead, the outside air can be directly introduced into the outdoor flow path OP and discharged, and although the regeneration ability of the desiccant element D is slightly weakened, the power of the lower fan F2 when the air is passed through the outdoor flow path OP can be saved.

Further, in the second operation mode, the upper valve 34 is switched between the first state and the second state, and the lower valve 44 is switched between the third state and the fourth state. Therefore, for example, the indoor air is the upper valve 34. After being dehumidified by the desiccant element D of the first flow path 34a, it is cooled by the indoor flow path IP to regenerate the desiccant element D of the second flow path 44b of the lower valve 44, and is heated by the outdoor flow path OP to be heated in the upper part. The desiccant element D of the second flow path 34b of the side valve 34 is regenerated and discharged to the outside of the room. On the other hand, the outside air is totally heat exchanged at the lower valve 44 and introduced into the room. That is, the outside air is dehumidified by the desiccant element D of the first flow path 44a of the lower valve 44 and introduced into the room, and the lower valve 44 has a certain heat capacity and is cooled by the second flow path 44b. The air introduced into the room is cooled through the first flow path 44a. Then, the first flow paths 34a and 44a and the second flow paths 34b and 44b are replaced by rotation, and the above is continuously performed. Therefore, it is possible to continuously exchange the outside air (cooling and drying) and introduce the outside air while ventilating.

Further, in the third operation mode, the lower valve 44 is maintained without being rotated, and the upper valve 34 is switched between the third state and the fourth state. Therefore, for example, the outside air temperature is higher than the room temperature and the indoor air is more humid than the outside air. When the temperature is low, the indoor air is discharged to the outside of the room after regenerating the desiccant element D of the first flow path 34a of the upper valve 34. On the other hand, the outside air is totally heat exchanged at the upper valve 34 and introduced into the room. That is, the outside air flows from the lower valve 44 through the outdoor flow path OP, is dehumidified in the second flow path 34b of the upper valve 34, then flows through the indoor flow path IP, and is introduced into the room through the lower valve 44. Further, since the upper valve 34 has a certain heat capacity and indoor air lower than the outside air temperature flows through the second flow path 34b, the air introduced into the room is cooled through the first flow path 34a. Then, the first flow path 34a and the second flow path 34b of the upper valve 34 are replaced by rotation, and the above is continuously performed. Therefore, it is possible to continuously exchange the outside air (cooling and drying) and introduce the outside air while ventilating.

Further, in the fourth operation mode, the upper valve 34 is maintained without being rotated, and the lower valve 44 is switched between the third state and the fourth state. Therefore, for example, the outside air temperature is higher than the room temperature and the indoor air is more humid than the outside air. When the temperature is low, the indoor air flows from the upper valve 34 through the indoor flow path IP, regenerates the desiccant element D of the second flow path 44b of the lower valve 44, then flows through the outdoor flow path OP, and flows through the upper valve 34 to the outside. Is discharged to. On the other hand, the outside air is totally heat exchanged at the lower valve 44 and introduced into the room. That is, the outside air is introduced into the room after being dehumidified in the first flow path 44a of the lower valve 44. Further, since the lower valve 44 has a certain amount of heat capacity and indoor air lower than the outside air temperature flows through the second flow path 44b, the air introduced into the room is cooled through the first flow path 44a. Then, the first flow path 44a and the second flow path 44b of the lower valve 44 are replaced by rotation, and the above is continuously performed. Therefore, it is possible to continuously exchange the outside air (cooling and drying) and introduce the outside air while ventilating.

Further, in the fifth operation mode, when the outside air is introduced into the underfloor space UFC, the lower fan F2 is driven and the lower fan F2 and the underfloor space UFC are connected to the first flow path 44a of the lower valve 44 or the first flow path 44a. Connect with 2 flow paths 44b. On the other hand, when exhausting from the underfloor space UFC, the upper fan F1 is driven and the upper indoor valve 37 is opened, and the indoor flow path IP and the underfloor space UFC are connected to the first flow path 44a of the lower valve 44. Alternatively, it is connected by the second flow path 44b, and the upper fan F1 and the upper outdoor space UCO (outdoor) are connected by the first flow path 34a or the second flow path 34b of the upper valve 34. As a result, exhaust from the underfloor space UFC and intake to the underfloor space UFC can be alternately performed by time allocation (for example, every 180 seconds).

Further, in the sixth operation mode, the lower fan F2 is driven, and the lower fan F2 and the underfloor space UFC are connected by the first flow path 44a or the second flow path 44b of the lower valve 44, and the upper fan is connected. While driving F1, the upper fan F1 and the upper outdoor space UCO (outdoor) are connected by the first flow path 34a or the second flow path 34b of the upper valve 34. As a result, the lower unit 40 can introduce the outside air into the underfloor space UFC, while the upper unit 30 can discharge the indoor air.

Further, in the seventh operation mode, when the outside air is introduced into the room, the lower fan F2 is driven and the lower fan F2 and the indoor flow path IP are connected by the third flow path 44c of the lower valve 44. The upper fan F1 and the indoor flow path IP are connected by the first flow path 34a or the second flow path 34b of the upper valve 34. On the other hand, when exhausting from the room, the upper fan F1 is driven, and the upper fan F1 and the upper outdoor space UCO (outdoor) are connected by the first flow path 34a or the second flow path 34b of the upper valve 34. Connecting. As a result, exhaust from the room and intake into the room can be alternately performed by time allocation (for example, every 180 seconds).

Further, in the seventh operation mode, when the outside air is introduced into the room, the upper indoor valve 37 is opened. Therefore, when introducing the outside air, the outside air can be introduced not only by the first flow path 34a or the second flow path 34b of the upper side valve 34 but also by the flow path released by the upper side indoor valve 37, and the outside air introduction resistance is increased. It can be reduced and contribute to the smooth introduction of outside air.

Further, in the eighth operation mode, the upper fan F1 is driven, and the upper fan F1 and the indoor flow path IP are connected by the first flow path 34a or the second flow path 34b of the upper valve 34 to form an indoor flow. The road IP and the underfloor space UFC are connected by a first flow path 44a or a second flow path 44b of the lower valve 44. As a result, indoor air can be sent to the underfloor space UFC, cooled or heated by the latent heat storage material PCM in the underfloor space UFC, and returned to the floor space, and the comfort of the floor space using the latent heat storage material PCM can be circulated inside the air. Can be done by.

Further, according to the upper valve 34 and the lower valve 44 according to the first embodiment, it is possible to provide valves 34 and 44 that can contribute to the miniaturization of the air conditioner 1. Further, when the third flow paths 34c and 44c are provided, it is possible to contribute to the realization of various controls using the linear flow path.

Next, a second embodiment according to the present invention will be described. The air conditioner according to the second embodiment has a common configuration with that of the first embodiment, but some configurations are different. Hereinafter, the differences from the first embodiment will be described.

FIG. 16 is a schematic configuration diagram showing an air conditioner according to the second embodiment. The air conditioner 2 shown in FIG. 16 includes a central outdoor unit 50, a central indoor side unit 60, an upper unit 70, a lower unit 80, and a control device (control means) CD.

FIG. 17 is a schematic configuration diagram of the central outdoor unit 50 shown in FIG. As shown in FIG. 17, the central outdoor unit 50 has two plate members 51 and 52, a peripheral end member 53, a plurality of first prisms 54, a separation wall 55, a plurality of second prisms 56, and a plurality of selective absorptions. It includes an air-conditioning structure (air-conditioning plate material) ACS having a film 57, and a heating flow path forming plate material 58.

The two plate materials 51 and 52 are flat plate-shaped plate materials that have a space and are arranged substantially in parallel with each other. Of these plate materials 51 and 52, the second plate material 52 on the outdoor side is a transparent plate material. Further, the first plate material (indoor side plate material) 51 on the indoor side is preferably one having excellent thermal conductivity. The peripheral end member 53 is provided at the peripheral end portion of the two plate members 51 and 52. A plurality of first prisms 54, a separation wall 55, a plurality of second prisms 56, and a plurality of selective absorption films 57 are housed in the internal space formed by the two plate members 51 and 52 and the peripheral end member 53. To.

FIG. 18 is an enlarged view showing the plurality of first prisms 54 shown in FIG. The plurality of first prisms 54 are prisms (that is, triangular prism-shaped prisms) each having a triangular shape when viewed in cross section. These first prisms 54 are arranged so that the first side 54a faces the second plate member 52 so that the first side 54a is along the second plate member 52 on the outdoor side. The second side 54b and the third side 54c of the first prism 54 extend at a predetermined angle with respect to the first side 54a. The second side 54b is a side located vertically below the third side 54c.

Such a first prism 54 is composed of a solid transparent member. The first prism 54 may be composed of an outer wall member and a liquid, a gel-like body, or a solid housed inside the outer wall member. Further, the second plate material 52 may be used as a part of the outer wall member, or the second plate material 52 may not be used as a part of the outer wall member such as a triangular pipe.

Here, the refractive index and each internal angle of the first prism 54 are set so that the sunlight Ray incident on the first side 54a is totally reflected and emitted from the second side 54b. ..

That is, in the first prism 54, the refractive index and each internal angle of the triangle are set so that the following three types of optical paths OP1 to OP3 are realized. Here, in the first optical path OP1 among the three types of optical paths OP1 to OP3, the sunlight Ray that has passed through the second plate member 52 and entered into the first prism 54 from the first side 54a is directly on the second side. It reaches 54b and goes out of the first prism 54 from the second side 54b. In the second optical path OP2, the sunlight Ray is totally reflected on the third side 54c, reaches the second side 54b, and goes out of the first prism 54 from the second side 54b. The third optical path OP3 reaches the second side 54b after being totally reflected in the order of the third side 54c and the first side 54a, and goes out of the first prism 54 from the second side 54b.

Further, the first prism 54 can pass the scattered light SL when the sunlight Ray is reflected on the ground or the like by setting the angle of the internal angle of the first prism 54.

See FIG. 17 again. The isolation wall 55 has a zigzag shape when viewed in cross section, and a plurality of internal space ISs are formed by the isolation wall 55 and the first plate material 51. Each of the plurality of internal space ISs has a triangular shape when viewed in cross section. These internal space ISs are provided with an internal member (for example, a liquid, a gel-like body, or a solid) serving as a second prism 56.

The first prism 54 and the second prism 56 have the same refractive index and the same shape, and are arranged so as to be point-symmetrical in the side view state shown in FIG. As a result, it is possible to suppress the distortion of the scenery that occurs when the scattered light SL is refracted by the first prism 54 and visually recognized from the indoor side. That is, the second prism 56 functions as an image recovery prism.

The plurality of selective absorption films 57 are provided apart from the second side 54b (see FIG. 18) of the first prism 54, and the side 56b of the second prism 56 facing the second side 54b (FIG. 18). It is provided in contact with (see 18). Such a selective absorption film 57 has a large absorption rate in the sunlight wavelength region (0.3 to 2.5 μm) and a low emissivity in the infrared wavelength region (3.0 to 20 μm). The plurality of selective absorption films 57 may be arranged in the internal space IS as long as they are provided for the side 56b, or may be attached on the isolation wall 55 outside the internal space IS. good.

Due to such a configuration, the air-conditioning structure ACS emits the sunlight Ray incident through the second plate material 52 from the second side 54b of the first prism 54 and irradiates the selective absorption film 57. Become. Further, since the selective absorption film 57 is separated from the first prism 54 and is provided in direct or indirect contact with the second prism 56, the second prism 56 is heated, and the second prism 56 and the second prism 56 and the second prism 56 are heated. The indoor side of the first plate material 51 is heated through the first plate material 51.

The heating flow path forming plate 58 is a flat plate-shaped plate arranged on the indoor side of the air-conditioning structure ACS, and has a predetermined gap so as to be substantially parallel to the first plate 51 of the air-conditioning structure ACS. It is placed adjacent to each other. The heating flow path forming plate material 58 is arranged adjacent to the first plate material 51 with a predetermined gap, so that the gap between the first plate material 51 and the heating flow path forming plate material 58 is filled with the heating flow path. Make it function as HP.

FIG. 19 is a schematic configuration diagram showing the central indoor side unit 60 shown in FIG. In FIG. 19, the heating flow path forming plate 58 of the central outdoor unit 50 is also shown.

As shown in FIG. 19, the central indoor side unit 60 is composed of three flat plate-shaped plate members 61 to 63 and a spacer 64. The first plate material 61 is a plate material that is arranged in parallel with the heating flow path forming plate material 58 via the spacer 64. The second plate material 62 is a plate material that is arranged in parallel with a predetermined gap from the first plate material 61. This gap becomes the first air flow path AP1. The third plate material 63 is a plate material that is arranged in parallel with a predetermined gap as compared with the second plate material 62. This gap becomes the second air flow path AP2.

With such a configuration, the first air flow path AP1 and the second air flow path AP2 become a flow path extending at least in the vertical direction, and the outdoor side of the second air flow path AP2 is adjacent to the first air flow path AP1. The indoor side becomes a flow path adjacent to the indoor.

The space sandwiched between the first plate member 61, the spacer 64, and the heating flow path forming plate member 58 is in a vacuum state. Therefore, the space functions as a vacuum heat insulating layer, and it is difficult for heat from the heating flow path HP to transfer to the first air flow path AP1.

FIG. 20 is a schematic configuration diagram showing the upper unit 70 shown in FIG. The upper unit 70 is arranged above the central outdoor unit 50 and the central indoor unit 60. The upper unit 70 includes an upper first flow path 71, an upper second flow path 72, an upper third flow path 73, an upper fourth flow path 74, a valve 75, a valve seat 76, and a dropping portion. It includes 77, a switching valve 78, and an upper fan F1.

The upper first flow path 71 and the upper second flow path 72 are flow paths having one end connected to the outside of the room. An upper fan F1 is provided near the center of the upper first flow path 71. The upper fan F1 takes in outside air from one end side (outdoor) of the upper first flow path 71 and scavengs it to the other end side. The upper second flow path 72 is a flow path adjacent to the lower side of the upper first flow path 71.

A valve 75 and a valve seat 76 are provided on the other end side of the upper first flow path 71 and the upper second flow path 72. Since the valve 75 is the same as the upper valve 34 and the lower valve 44 according to the first embodiment, and the valve seat 76 is the same as the valve seats 35 and 45 according to the first embodiment, the description thereof will be omitted.

In the valve seat 76, the first open portion O1 is connected to the other end of the upper first flow path 71, and the second open portion O2 is connected to the first air flow path AP1. Further, the third open portion O3 is connected to the heating flow path HP, and the fourth open portion O4 is connected to the other end of the upper second flow path 72. By controlling the rotation of the valve 75, these connections are changed.

The upper third flow path 73 is a flow path in which one end is connected to the second air flow path AP2 and the other end is connected to the outside of the room. The upper fourth flow path 74 is a flow path in which one end is connected to the middle of the upper third flow path 73 and the other end is connected to the room. The upper third flow path 73 is provided with a dropping portion 77 and a switching valve 78.

The dropping portion 77 drops a liquid (for example, water) from the upper third flow path 73 to drop the liquid on the surface of the second plate material 62 and the third plate material 63 on the second air flow path AP2 side. There is (see FIG. 16). The liquid that has reached the lower end of the second air flow path AP2 is pulled up to the dropping portion 77 again by a pump (not shown). Further, the liquid in the dropping portion 77 can be replenished.

The switching valve 78 is provided at the connection portion between the upper third flow path 73 and the upper fourth flow path 74. The switching valve 78 has an outdoor connection state (see the solid line) that connects one end and the other end of the upper third flow path 73 and shuts off the upper fourth flow path 74, and one end and the other end of the upper third flow path 73. It is possible to switch between the indoor connection state (see the broken line) and the indoor connection state (see the broken line) in which the above is cut off and the upper fourth flow path 74 is opened.

Here, the valve 75 is rotationally controlled and may take the fifth to seventh states. The fifth state of the valve 75 is the state shown in FIG. That is, in the fifth state, the first flow path 75a connects the heating flow path HP and the upper second flow path 72 (outdoor), and the second flow path 75b is the upper first flow path 71 (outdoor). And the first air flow path AP1 are connected.

The sixth state of the valve 75 is a state rotated by 180 ° from the state shown in FIG. That is, in the sixth state, the first flow path 75a connects the upper first flow path 71 (outdoor) and the first air flow path AP1, and the second flow path 75b connects the heating flow path HP and the upper second flow path. It is in a state of being connected to the flow path 72 (outdoor side).

The seventh state of the valve 75 is a state in which the valve 75 is rotated 90 ° clockwise or counterclockwise from the fifth state, and the first flow path 75a or the second flow path 75b is the heating flow path HP and the first air flow. It is in a state of being connected to the road AP1. The seventh state is shown in FIG. 22, which will be described later.

FIG. 21 is a schematic configuration diagram showing the lower unit 80 shown in FIG. As shown in FIG. 21, the lower unit 80 includes a lower first flow path 81, a lower second flow path 82, a lower third flow path 83, a total heat exchange element 84, and a flow path on-off valve 85. , The lower side fan F2 is provided.

The lower first flow path 81 and the lower second flow path 82 are flow paths that connect the outdoor side and the total heat exchange element 84. A lower fan F2 is provided in the lower first flow path 81. The lower fan F2 takes in outside air from one end side (outdoor) of the lower first flow path 81 and scavengs it to the total heat exchange element 84 on the other end side. The lower second flow path 82 is a flow path adjacent to the upper side of the lower first flow path 81.

The lower third flow path 83 is a flow path connecting the room and the total heat exchange element 84. A flow path on-off valve 85 is provided at the indoor end of the lower third flow path 83. The flow path on-off valve 85 is a valve that can be switched between an open state in which the indoor end of the lower third flow path 83 is opened and a closed state in which the indoor end is closed.

The total heat exchange element 84 exchanges total heat between the indoor air from the lower third flow path 83 and the outside air taken into the lower first flow path 81 by driving the lower fan F2. After the total heat is exchanged, the indoor air is discharged to the outside through the lower second flow path 82. The outside air is introduced into the heating flow path HP after the total heat exchange.

Louvers are provided on the outdoor side of the upper first to third flow paths 71 to 73 of the upper unit 70 and on the indoor side of the upper fourth flow path 74, and can be shut off when air does not flow. There is. Further, louvers are also provided on the indoor side of the lower first and second flow paths 81 and 82 of the lower unit 80, and can be shut off when air does not flow.

The control device CD shown in FIG. 16 controls the entire air conditioner 2, and controls the rotation of the valve 75, the drive control of the upper fan F1 and the lower fan F2, the opening / closing control of the louver, and the valve 78. , 85 switching control and the like are executed. The control device CD can control these to execute two operation modes (cooling operation mode and heating operation mode) by designating the operation mode from the user or by automatic control.

Next, the operation of the air conditioner 2 according to the present embodiment in each operation mode will be described with reference to FIGS. 16 and 22.

As shown in FIG. 16, in the cooling operation mode, the control device CD opens all the louvers and drives the upper and lower fans F1 and F2. Further, in the control device CD, the switching valve 78 is in the outdoor connection state, and the flow path on-off valve 85 is in the closed state. Further, the control device CD drives the dropping portion 77 to drop the liquid on the inner surfaces (second air flow path AP2 side) of the second plate material 62 and the third plate material 63.

In this state, the control device CD rotates the valve 75 at predetermined time (for example, 180 seconds) intervals, and switches the valve 75 between the fifth state and the sixth state at predetermined time intervals.

As a result, the outside air is introduced into the lower first flow path 81 by the lower fan F2 and is heated in the heating flow path HP. The heated air is supplied to one of the first and second flow paths 75a and 75b of the valve 75, regenerates the desiccant element D, and then is discharged to the outside through the upper second flow path 72.

Further, the outside air is introduced into the upper first flow path 71 by the upper side fan F1 and then supplied to the other of the first and second flow paths 75a and 75b of the valve 75. The supplied air is dehumidified by the desiccant element D and reaches the first air flow path AP1. The dehumidified air passes through the first air flow path AP1 and reaches the second air flow path AP2.

Since the liquid is dropped in the second air flow path AP2, the liquid is vaporized by the dehumidified air and the indoor side is cooled by the heat of vaporization. In addition, since the liquid on the first air flow path AP1 side is also vaporized and cooled, the air flowing from the first air flow path AP1 to the second air flow path AP2 is also cooled, and the cooling air is cooled by the second air flow. The room is also cooled by flowing through the road AP2. The air that has passed through the second air flow path AP2 is discharged to the outside through the upper third air flow path 73.

As a result, in the cooling operation mode, radiant cooling can be performed via the third plate material 63.

FIG. 22 is an operating state diagram of the air conditioner 2 in the heating operation mode. As shown in FIG. 22, in the heating operation mode, the control device CD opens all the louvers and drives the upper and lower fans F1 and F2. Further, in the control device CD, the switching valve 78 is in the indoor connection state, and the flow path on-off valve 85 is in the open state. Further, the control device CD drives the dropping portion 77 to drop the liquid on the inner surfaces (second air flow path AP2 side) of the second plate material 62 and the third plate material 63. In this state, the control device CD maintains the valve 75 in the seventh state.

As a result, the outside air is introduced into the lower first flow path 81 by the lower fan F2, and reaches the heating flow path HP after total heat exchange by the total heat exchange element 84 (after heating and humidification). The air introduced into the heating flow path HP reaches the valve 75 after being heated, passes through the first or second flow paths 75a and 75b of the valve 75, and is supplied to the first air flow path AP1.

The air supplied to the first air flow path AP1 passes through the first air flow path AP1 and reaches the second air flow path AP2. Since the liquid is dropped in the second air flow path AP2, the air is humidified and supplied into the room from the upper third flow path 73 through the upper fourth flow path 74.

Thereby, in the heating operation mode, humidified and heated air can be supplied to the room.

On the other hand, the indoor air reaches the total heat exchange element 84 through the lower third flow path 83, is totally heat exchanged in the total heat exchange element 84, and then is discharged to the outside through the lower second flow path 82.

In this way, according to the air conditioner 2 according to the second embodiment, it is possible to further reduce the size as in the first embodiment.

Further, the switching valve 78 is controlled to connect the second air flow path AP2 to the outdoor side, the valve 75 is rotated at predetermined time intervals, and the valve 75 is set to the fifth state and the sixth state at predetermined time intervals. It is controlled by the cooling operation mode to be switched and the heating operation mode in which the switching valve 78 is controlled to connect the second air flow path and the indoor side and the valve is maintained in the seventh state. Therefore, in the cooling operation mode, one of the first and second flow paths 75a and 75b, the desiccant element D, is regenerated by the air heated by the air conditioning structure ACS, and the other desiccant element D dehumidifies the outside air. The dehumidified air passes through the first air flow path AP1 and reaches the second air flow path AP2. Since the liquid is dropped in the second air flow path AP2, the liquid is vaporized by the dehumidified air and the indoor side is cooled by the heat of vaporization. In addition, since the liquid on the first air flow path AP1 side is also vaporized and cooled, the air flowing from the first air flow path AP1 to the second air flow path AP2 is also cooled, and the cooling air is cooled by the second air flow. The room is also cooled by flowing through the road AP2. Therefore, the room can be cooled. Further, in the heating operation mode, the air heated by the air conditioning structure ACS flows through one of the first and second flow paths 75a and 75b and is discharged into the room through the first air flow path AP1 and the second air flow path AP2. And can heat the room. Therefore, it is possible to provide an air conditioner 2 capable of heating and cooling.

Further, according to the valve 75 according to the second embodiment, it is possible to provide the valve 75 that can contribute to the miniaturization of the air conditioner 2 as in the first embodiment. In the second embodiment, the third flow path of the valve 75 is not used in both the cooling operation mode and the heating operation mode, but various controls are performed by using the linear third flow path. It may be useful for.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and changes may be made without departing from the spirit of the present invention, and the present invention may be appropriately implemented to the extent possible. The forms may be combined with each other. Further, known or well-known techniques may be combined to the extent possible.

For example, in the first embodiment, the air conditioning structure ACS uses the absorption refrigeration cycle to cool the first plate material 21 side and heat the second plate material 22 side, but the present invention is not limited to this, and the second plate material 22 is not limited to this. It may only heat the side (it may have no cooling effect). In particular, when it has no cooling effect, it can be suitably operated during heating in winter.

FIG. 23 is a schematic configuration diagram showing a modified example of the air conditioning structure ACS. In the first embodiment, the air conditioning structure ACS may be the one shown in FIG. 23. The air-conditioning structure ACS shown in FIG. 23 has a structure in which the air-conditioning structure ACS shown in FIG. 16 is turned upside down by 180 °, and the first and second plate materials (indoor side plate material, outdoor plate material) 101, 102. , A peripheral end member 103, a plurality of first prisms 104, an isolation wall 105, a plurality of second prisms 106, and a plurality of selective absorption films 107.

In this air-conditioning structure ACS, sunlight is efficiently collected on the selective absorption film 107 by the second prism 106, and the second prism 106 is heated. The heated second prism 106 heats the second plate material (outdoor plate material) 102. In this modification, the first prism 104 is a prism dedicated to image recovery.

FIG. 24 is a schematic configuration diagram showing a second modification of the air conditioning structure ACS. In the first embodiment, the air conditioning structure ACS may be the one shown in FIG. 24.

The air-conditioning structure ACS according to the example shown in FIG. 24 includes substantially two plate members 201 and 202, a peripheral end member 203, a slope 210, and a working liquid (liquid) HF.

The two plate materials 201 and 202 are transparent plate materials that are arranged substantially in parallel with each other. These plate materials 201 and 202 are made of, for example, a glass material.

The peripheral end member 203 is interposed between the two plate materials 201 and 202 at the peripheral end portions of the two plate materials 201 and 202. By providing the peripheral end member 203 at the peripheral end portion of the two plate members 201, 202, an internal space closed by the two plate members 201, 202 and the peripheral end member 203 is formed. In the present embodiment, the internal space is in a vacuum state from the viewpoint of heat insulating properties, but the present invention is not limited to this, and the internal space may be filled with a predetermined gas.

The slope 210 is a transparent member interposed between the two plate members 201 and 202, and is folded twice at 90 ° in the cross-sectional view shown in FIG. 24 to form a bent body having a substantially N-shaped cross section. There is. One end 210a of the slope 210 is in contact with the inner wall of the first plate material (indoor side plate material) 201, and the other end 210b is provided in contact with the inner wall of the other plate material (outdoor plate material) 202. There is. Such a slope 210 constitutes, on one end side, a storage portion Res capable of storing the hydraulic fluid HF together with the first plate material 201.

FIG. 25 is a perspective view showing the details of the slope 210 shown in FIG. 24. As shown in FIG. 25, the slope 210 is composed of a lower plate 211, an upper plate 212 arranged in parallel with the lower plate 211, and a connecting plate 213 connecting them.

The lower plate 211 has the above-mentioned end portion 210a, and the opposite side of the end portion 210a is a comb tooth portion 211a protruding like a comb tooth. Each end face EF of the comb tooth portion 211a is a portion in contact with the inner wall of the second plate material 202. The upper plate 212 has a point-symmetrical structure with the lower plate 211 with the connection plate 213 interposed therebetween. That is, the upper plate 212 has a comb tooth portion 212a on which the opposite side of the end portion 210b protrudes like a comb tooth, and each end surface EF of the comb tooth portion 212a is a portion in contact with the inner wall of the first plate material 201. In this way, in the slope 210, both ends (end 210a and end face EF) of the lower plate 211 and both ends (end 210b and end face EF) of the upper plate 212 are in contact with the two plate materials 201 and 202, respectively. .. As a result, the slope 210 supports the two plate members 201 and 202 in a vacuum state from the inside thereof.

See FIG. 24 again. In the present embodiment, the working liquid HF is a transparent liquid such as water. The hydraulic fluid HF is not limited to water. Such a hydraulic fluid HF is stored in the storage unit Res. The hydraulic fluid HF of the reservoir Res can be evaporated by the heat from the first plate material 201. The evaporated hydraulic solution HF becomes vapor and reaches the second plate material 202. The working liquid HF that has become vapor is condensed and liquefied in the second plate material 202. The liquefied hydraulic fluid HF flows down the inner surface of the second plate material 202 and collects on the upper plate 212 (see FIG. 25) of the slope 210. When a certain amount or more of the working liquid HF is accumulated on the upper plate 212, the working liquid HF falls from the gap of the comb tooth portion 212a of the upper plate 212 to the storage portion Res.

Specifically, when the room temperature is 20 ° C. and the outside air temperature is 25 ° C., the vapor pressure of the water (working liquid HF) accumulated in the reservoir Res is about 2.4 kPa, and the internal space is 2. It functions as a heat insulating glass in a vacuum state of about 5/100 atm. When the room temperature rises to 30 ° C from this state, the evaporation of water progresses and the pressure in the internal space tries to rise to 4.3 kPa, but the evaporated water (water vapor) is cooled when it touches the second plate material 202 on the outdoor side. And liquefies, and flows down the inner surface of the second plate material 202. The flowing water returns to the reservoir Res via the upper plate 212 of the slope 210.

In this way, the hydraulic fluid HF returns from the reservoir Res to the reservoir Res again via the second plate material 202, and the slope 210 has a liquid circulation structure that enables such circulation of the hydraulic fluid HF. It has become. Further, the first plate material 201 functions as an evaporator because the working liquid HF evaporates, and the second plate material 202 functions as a condenser because the working liquid HF condenses. Therefore, the heat of vaporization is taken away from the first plate material 201 side and cooled, and the heat of condensation is discarded from the second plate material 202 side. As a result, the heat on the first plate material 201 side flows through to the second plate material 202 side. For example, in the summer, the indoor side becomes the first plate material 201, so that the room can be made comfortable without taking in moisture. When the room temperature is low in the summer, the working liquid HF can function as a heat insulating glass without evaporating.

As described above, the air-conditioning structure ACS does not have to constantly cool the first plate material 201 side and heat the second plate material 202 side, and cools the first plate material 201 side when a predetermined condition is satisfied. The second plate material 202 side may be heated.

Further, in the first operation mode of the above embodiment (particularly when the air conditioning structure ACS shown in FIG. 23 is used), only the upper valve 34 may be held to control the rotation. As a result, the desiccant element D can be continuously regenerated and the indoor air can be continuously dried.
