The 44-way rotation is performed by switching the four-way valve 2 and performing reverse defrosting. However, during this reverse defrosting operation, the refrigerant returned to the compressor 1 is heated and evaporated, so the returned refrigerant is transferred to the heat storage tank 6. While passing through the heat storage tank 6, it absorbs heat and is heated.

A heat storage tank 6 is installed independently, and heat storage is carried out by guiding the high-temperature discharged refrigerant from the compressor 1 through the heat exchange coil 7vC through valve operation. Due to this trap, switching operations between heat storage in the heat storage tank 6 and heat radiation in the refrigerant heating tank are troublesome and complicated, and piping is complicated because various valves are arranged in the refrigeration cycle, leading to high costs. Moreover, since the heat storage tank 6 is independent, the installation space becomes large, making it difficult to achieve miniaturization.

クションカップ；３１に接続される。Further, a heat storage piping path is connected in parallel to the low pressure side refrigerant arrangement 25b extending from the four-way valve 21 to the suction side of the compressor. The heat storage piping base is equipped with four heat exchange coils for heat absorption in the middle,
This heat exchange coil 29 is housed in a heat storage tank blade filled with a heat storage agent. As shown in FIG. 3, the heat storage tank (9) covers the compressor case 20a from the outside and is provided integrally or integrally with the compressor case 20a. The heat exchange coil 29 for heat absorption accommodated in the heat storage tank I extends in the circumferential direction,
The other end comes out of the heat storage tank and is connected to a suction cup 31 of a compressor.
ところで、前記低圧側冷媒配管２５ｂと蓄熱用配管路と
の分岐部には切換用三方弁３３が設けられる。By the way, a three-way switching valve 33 is provided at the branching point between the low-pressure side refrigerant pipe 25b and the heat storage pipe.

低コストで製造できる。By energizing the electromagnetic coil of the three-way switching valve, the valve element 37 closes the valve seat 36m, and the inlet bow (35) is communicated with one outlet bow (36b), thereby canceling the energization. This communicates with the other outflow port 36a. When this three-way valve is switched, the refrigerant pressure acting on each of the three-way valve 33's inflow and outflow ports (35, 36, and 36b) is low pressure, and there is almost no pressure difference between the outflow and inflow ports, so the three-way valve
Even if the valve 3 has a large diameter, the valve switching operation can be performed smoothly with a small switching force. Therefore, the three-way valve can be a simple and simply purchased direct-acting valve, and the electromagnetic coil 40 can also be small. In addition, since the three-way valve 33 does not cause any inconvenience even if a small amount of refrigerant leaks from the switching part,
Can be manufactured at low cost.

４に案内され、ここで吸熱し、周囲の空気を冷却する。During cooling operation, the four-way valve 21 and the three-way valve are set to the state shown in FIG. 2. The refrigerant discharged from the compressor nozzle is sent to the outdoor heat exchanger via the four-way valve 21, where it radiates heat to the surroundings and is condensed. This condensed refrigerant passes through the expansion valve B, undergoes an expansion action, and then enters the indoor heat exchanger 2.

ている。On the other hand, during heating operation, the four-way valve 21 is switched to the heating operation side. By this switching, the high-temperature, high-pressure refrigerant discharged from the compressor is sent to the outdoor heat exchanger via the west valve 21, where it radiates heat and warms the surrounding air. The heated air is blown into the room as hot air, heating the room.

切り換えられない限り、放熱されない。By the way, when the compressor is running, the heat radiated from the compressor case 20a is transferred to the heat storage tank 30 by thermal conduction.
The heat is transferred to the inside and stored in the heat storage tank over time. The heat stored in the heat storage tank blade will not be radiated unless the three-way valve is switched to the heat storage amount g281 rule.

着した１゛６を急速に除霜することができる。As a result, the high-temperature, high-pressure refrigerant from the combination is guided directly to the outdoor heat exchanger via the hot gas bypass circuit, where it radiates heat and removes the frost that has adhered to the fins of the indoor heat exchanger. By defrosting the outdoor heat exchanger 22, the condensed refrigerant is guided into the heat storage tank (branch) via the four-way valve 21 and the three-way valve 33, and is transferred to the heat exchange coil 29 for heat absorption.
While passing through, it undergoes an endothermic action and evaporates, becoming a gas refrigerant.
This gas refrigerant is returned to the compressor through the satanyong bag 31. Therefore, it is possible to rapidly defrost the 1-6 adhering to the outdoor heat exchanger 22.

By directing the remainder to the outdoor heat exchanger blades via the four-way valve 21,
Pain relief operation can be performed while heating operation is continued, and heating operation can be performed continuously.

要とせず、小型化を図ることができる。One more time! As mentioned above, in the refrigeration cycle VC according to the present invention, a heat storage pipe with an innovative heat absorption heat exchange coil can be connected in parallel and switchably to the low pressure side refrigerant pipe from the four-way valve to the compressor suction side. Since the heat storage tank housing the above-mentioned heat exchange coil is connected and arranged so that it can exchange heat with the compressor, the heat dissipated from the compressor case can be actively used to store heat in the heat storage tank. There is no need to provide a heat exchange coil for heat radiation inside the tank, and the life inside the heat storage tank can be simplified accordingly. In addition, since the heat storage tank is arranged so that it can exchange heat with the compressor, it can be placed closer to the compressor, and the installation space can be used more effectively, so it does not require a large installation space and can be downsized. can be achieved.
