A heat pump composed of b, 12-c, 12-d and a heat storage tank 7 containing a heat storage material 8 are thermally coupled via a heat exchanger 11. The heat medium (Freon, etc.) adiabatically compressed by the compressor 6 passes through the discharge side pipe 12-a and enters the condenser 1, where heat is removed by the air sent by the fan 3. After passing through the pipe 12-c, the pressure reducing mechanism 5 (expansion valve or capillary tube) enters. The heat medium that has been adiabatically expanded here enters the evaporator 2 while the temperature decreases, and here, heat is acquired from the air sent by the fan 4,
After passing through the suction side pipe 12-b, it returns to the compressor 6 and repeats the same cycle. That is, the heat is taken from the outside on the evaporator 2 side, the heat is radiated on the condenser 1 side, and is used for heating or hot water supply. At this time, since the heat obtained on the side of the evaporator 2 may be insufficient in time, the heat is stored in the heat storage tank 7 in a time zone in which a large amount of heat exists.

The heat medium (water, oil, etc.) in the pipes 23, 23 'is circulated, and the heat on the discharge side of the compressor 6 is transferred to the heat storage material 8 and stored therein. At the time of heat radiation, the pump 10 is similarly driven to transfer the heat held by the heat storage material 8 to the heat exchanger 11 side, and the discharge side pipe 12
-The heat medium in a is heated and the heat is radiated from the condenser 1 to compensate for the insufficient heating capacity of the heat pump.

一部を使つても良い。FIG. 2 is a block diagram of the chemical heat storage system of the present invention. Among them, the heat pump is the same as the conventional one. The chemical heat storage device comprises a first container 13 for containing a reaction material 15 and a second container 14 for containing a material 16 to be reacted, which are connected by a vapor transfer pipe 17 having a pulp 18 as shown in the drawing. Further, the heat exchanger 9 is provided in the reaction material 15, and the heat exchanger 11 provided in the discharge side pipe 12-a of the compressor 6 and the pump 10 are provided.
Are connected by pipes 23 and 23 'having a pipe so as to form a circulation path as shown in the figure. Further, a heat exchanger 19 is provided in the reacted material 16, and the suction side pipe 12- of the compressor 6 is
Pipe 2 having heat exchanger 22 and pump 20 provided in part b
1, 21 'are connected so as to form a circulation path as shown in the figure. As the reaction material 15, zeolite, calcium chloride dihydrate CaCl 2 .2H 2 O, sodium fluide Na 2 S, and as the reaction material 16, water, methanol or the like is used. Reactive material 15
Heat is taken out while reacting the reaction target material 16 with the reaction target material 16, and is decomposed and regenerated for use while heating while storing heat. The procedure will be described in detail below. In the heat pump, when there is excess heat, the pump 10 is driven to transfer the heat on the discharge side of the compressor 6 to the reaction material 15 via the heat exchangers 11 and 9. As a result, the reacted material 16 in the reaction material 15 is decomposed and vaporized. This vapor reaches the second container 14 through the vapor transfer pipe 17, where it releases the heat of condensation and liquefies. The most important point in the chemical heat storage system of the present invention is that the condensation heat and the sensible heat held by the reacted material 16 are recovered in the heat pump at the same time as the decomposition and regeneration of the reaction material 15 so that the thermal efficiency is not lowered. That is. That is, when the reaction material 15 is decomposed, in addition to the energy required for the decomposition, energy for heating the reaction target material 16 to vaporize it is also necessary, but this energy, that is, the above-mentioned condensation heat and sensible heat, is left as it is. If left unattended, heat will be dissipated in vain, leading to a decrease in efficiency. Therefore, the pump 20 is driven so that the heat medium (water,
Oil or the like) is circulated in the heat exchangers 19 and 22, and the above-mentioned condensation heat and sensible heat are transmitted to the heat medium flowing in the pipe 12-b on the suction side of the compressor 6 and recovered. When the decomposition / regeneration operation of the reaction material 15, that is, the heat storage operation is completed in this way, the valve 18 is closed.
If the valve 18 is closed, the reaction between the reaction material 15 and the material to be reacted 16 does not occur, so there is no exothermic reaction of the reaction material 15, and accordingly heat is generated from the first container 13 to the outside as time passes. It does not start to disappear and disappear. That is, in such a chemical heat storage device, the reaction heat can be permanently stored by closing the valve 18 completely. Next, when it is desired to utilize this reaction heat, the valve 18 is opened. At this time, the reacted material 16 is naturalized, and the vapor thereof reaches the inside of the first container 13 through the vapor transfer pipe 17, where it reacts with the reactive material 15 to generate heat. By driving the pump 10, this heat is transferred to the heat medium of the discharge side pipe 12-a of the compressor 6 via the heat exchangers 19 and 11, and is used for heating or hot water supply. The evaporation of the reaction target material 16 in the second container 14 may cool the surroundings of the second container 14 and reduce the generation of steam. In such a case, it is preferable to heat from around the second container 14 or from the heat exchanger 19 side.
Combustion heat, waste heat, electricity, etc. are used. Alternatively, the pump 20 may be driven to use a part of the heat in the heat pump via the heat exchangers 22 and 19.

6, 26 'are used to connect the pipes 23, 23', respectively. In addition, the pipe 23, the pipe 26, the pipe 24,
25 is provided to change the flow of the heat medium. That is, at the time of heat storage, the valve 25 is closed and the valve 24 is opened,
The heat medium in the interior is flowed by the pump 10 into the heat exchangers 9 and 11 as in the embodiment of FIG. However, when the heat of the reaction material 15 is taken out and used, the valve 24 is closed and the valve is closed.
25 is opened and reaction heat is transferred to the heat medium in the suction side pipe 12-b of the compressor 6 via the heat exchangers 9 and 27. It is better to heat the heat medium flowing to the suction side in this way in terms of the heat pump cycle. In this embodiment, the heat exchanger 11 may be integrated with the condenser 1 as in the case of the heat exchanger 22.

近辺に配置しても良い。FIG. 4 shows another embodiment. This is a heat exchanger 22 arranged on the front surface of the condenser 2 as shown in the figure, so that the heat sent by the fan 4 can be acquired. When the reaction material 15 is decomposed and regenerated, in order to recover the condensation heat and sensible heat of the reaction target material 16, the fan 4 is rotated forward so that the air flows in the direction of the solid line and the heat of the heat exchanger 22 is changed to the air. To the evaporator 2 via. When the reaction material 15 and the material 16 to be reacted are reacted and the reaction heat is extracted and used, the fan 4 may be rotated in the reverse direction and flow in the direction of the broken arrow. In this embodiment, the heat exchanger 11 may be arranged in the vicinity of the condenser 1 like the heat exchanger 22.

In this case, the internal heat medium circulates in the order of the riser pipe 32, the liquid return pipe 31 ′, the heat exchanger 9, the vapor transfer pipe 33, the heat exchanger 11, and the liquid return pipe 31 by the pumping action of the bubbles. . On the other hand, in this embodiment, the heat generated by the reaction material 15 can also be transferred to the suction side pipe 12-b of the compressor 6. Therefore, a separate heat exchanger 36 is provided in the reaction material 15, and the heat exchanger 27 of the suction side pipe 12-b, the liquid reservoir tank 39, the liquid return pipe 38, the start-up pipe 41, the vapor transfer pipe are provided. 37, they are connected so as to form a circulation path as shown in the figure. When an input is applied to the riser pipe 40, the heat generated in the reaction material 15 is transferred to the heat medium in the suction side pipe 12-b via the heat exchangers 36 and 27 by the same principle as described above. Here, the reservoir tank 39
Is used for accumulating a large amount of heat medium, and contributes to ensuring the condensation area of the heat exchanger 27 and improving the efficiency of the bubble pumping power.
