Therefore, if hot water heated by carp A/4 is radiated by carp A/8, heating will be achieved more than K.

Hot water can be taken out from the hot water tank 9.

In such prior art, the adsorption action of the adsorbent 8 and the desorption and regeneration action are performed in a patch cycle. Therefore, hot water cannot be obtained during adsorption,

The present invention will be explained in detail below with reference to one drawing.

The ts2 diagram is a system diagram of an embodiment of the present invention. In this air-conditioning/heating/water supply device 11, the solar heat receiver 12 is filled with an adsorbent 18 such as zeolite, silica gel, activated alumina, or the like. A first reservoir 15 in which 14 tons of water as an adsorbent medium is stored is arranged below the solar heat receiver 12, and the solar heat receiver 12 and the first reservoir 15 are connected to a conduit 16t.

The water 14 in the air conditioner 5 is evaporated and adsorbed, and when the latent heat of vaporization is taken away during the evaporation of the water, the water 14 is cooled and the cold heat is used as a cold heat source during cooling operation. Further, when the vapor desorbed from the adsorbent 18 is condensed, the heat of condensation is used as a heat source during heating operation or hot water supply operation.

An air conditioner 81 equipped with a carp A/29 and a fan 801 is provided in a room to be cooled or heated. A heating circuit 82 is provided to generate warm air from the air conditioner 81 to achieve heating, and a cooling circuit 88 is provided to generate cold air from the air conditioner 82 to achieve air conditioning. The cooling circuit 88 can be switched freely by a three-way valve 84.

The heating circuit 82 includes a first heating coil A/85. pump 86,
Air conditioning/heating mat, three-way valve 84. and heating coil 87 are connected in this order to form a closed circuit. 1st heated carp/
I/85 is provided in the second reservoir 27, and heating coil A/85 is provided in the second reservoir 27.
87 is provided inside the outdoor condenser 28. In such a heating circuit 82, the water heated by the first heating coil A/85 by the hot water 26 in the second reservoir 27 is heated by the air conditioner 8.
After heat is radiated by the first coil 29 to achieve heating, heating is further applied by the heating coil A/87 of the outdoor condenser 28, and the heating coil returns to the first heating coil 85.

The cooling circuit 88 includes a cooling coil A'88. A bonded 86° air conditioner 81 and a three-way valve 84 are connected in this order to form a closed circuit. Cooling carp A/8g is provided in the first reservoir 15. In such a cooling circuit 88, the first
The water cooled by the cooling coil 88 by the cold water in the reservoir 15 is cooled by the coil A/29 of the air conditioner 81 to achieve cooling, and then returns to the cooling coil A'88.

A second heating coil 40 is provided in the second reservoir 27,
A hot water supply circuit 39 is constructed by arranging valves 41 and 42 before and after this heating coil 400. In this hot water supply circuit 89,
By opening the valves 41 and 42 to supply water, hot water heated by the second booster coil/L'40 can be supplied.

The cooling operation state will be explained with reference to FIG. In addition, in FIG. 2, unused conduits are indicated by broken lines. For example, during the sunshine hours from 6 a.m. to 7 p.m. in summer, the adsorbent 18 in the solar heat receiver 12 is heated and begins to desorb as it receives solar heat. This desorption action generates steam, which increases the pressure within the solar heat receiver 12 and increases the evaporation temperature. Therefore, evaporation of the water 14 in the first reservoir 15 is inhibited, making it difficult to obtain cold heat. Therefore, when performing cooling operation during desorption and regeneration of the adsorbent 18, the solenoid valve 18 is closed and the vacuum pump 17 is driven to suck the steam inside the solar heat receiver 12.
Keep the internal pressure relatively low. Then, the first reservoir 15
The evaporation of the water 14 inside is promoted, and the latent heat of evaporation is taken away, so that the water 14 becomes cold water. Therefore, the three-way valve 841 is switched to operate the cooling circuit 881. Then.

Cool air is obtained from the air conditioner/heater 81 and air conditioning is achieved. Therefore, cooling operation can be performed even when the adsorbent 18 is desorbed and regenerated.

The steam sucked by the vacuum pump 17 is transferred to the on-off valves 2B and 24.
ii) Open the valve and close the on-off valve 25ft: By keeping the valve closed, the condensate is introduced into the first condenser 20. Therefore, the steam is condensed in the first condenser 20, and the heat of condensation is given to the hot water 26 in the second reservoir 27. Therefore, hot water heated by the second heating coil A/40 of the hot water supply circuit 89 can be supplied.

Note that when the temperature of the hot water 26 in the second reservoir 27 is relatively high, the on-off valves 28 and 24 are closed, and the on-off valves 28 and 24 are closed.
5t-Open the valve. By doing so, the vacuum pump 17
The steam from the second condenser 2! is introduced and condensed.

Next, during the night, for example, from 7:00 pm to 6:00 the next morning, the vacuum pump 17 is stopped.

During this night Ktp, the water 14 in the first reservoir 15 is evaporated and adsorbed by the adsorbent 18 which is regenerated by solar heat as described above. Therefore, at night, cooling is achieved by driving the pump 86.

Incidentally, when cooling operation is not required during sunshine hours, the drive of the vacuum bonder 17 is stopped. Then, the water released from the adsorbent 18 will pass through the solenoid valve 18t to the first
The steam is led to the second condenser 20.21, and the heat of condensation of the steam is used to heat the hot water 26 in the second reservoir 27.

The heating operation state IIl will be explained with reference to FIG. In the heating operation fill, the three-way valve 84t is switched to operate the heating circuit 82. In this heating operation state, during sunshine, the heat of condensation of the steam is given from the first condenser 20 to the hot water 26 in the second storage Wh27 without driving the vacuum pump 17. Therefore, the hot water heated by the first heating coil 1v85 radiates heat by the coil A/29 of the air conditioner 31 to achieve heating, further radiates heat by the discharge coil A/37, and returns to the first heating coil 85. If the temperature of the hot water in the second reservoir 27 is sufficiently high during such heating operation.

The on-off valves 28 and 24 may be closed and the on-off valve 25 may be opened to condense the steam in the second condenser. In this case, the warm air obtained by outdoor condensation 1iF28 can also be used for indoor heating.

At night, the adsorbent 18 adsorbs moisture evaporated from the first reservoir 15, and no steam is generated from the solar heat receiver 12. When the vacuum pump 17t is driven at that time, the operation is performed in the same way as during the cooling operation described above. Steam can be led out from the solar heat receiver 12, and the heat of condensation of the steam can be recovered in the second storage device 27. Therefore, heating operation can be continued even at night.

As another embodiment of the present invention, the heating coil A/87 may be omitted, and the cooling coil A/88 may be omitted to make the Maki l reservoir 1
5 may be directly led to the air conditioner 81, or the first heating coil 85t may be omitted and the hot water 261 in the second reservoir 27 may be directly led to the air conditioner 81. Alternatively, the second heating coil pv40f may be omitted and the hot water 26r in the second reservoir 27 may be supplied. It is also possible to connect the first and second condensers 20 and 211 in series and drive the fan of the second condenser 21 to cool it when the temperature of the second reservoir 27 is high.

According to the above-mentioned invention, it is convenient to be able to freely switch between cooling, heating, and hot water supply operations, regardless of whether the adsorbent is acting as an adsorbent or desorbing and regenerating.
