A compressor 1, an indoor heat exchanger 2, an outdoor heat exchanger 3, and a pressure reducing mechanism 4 are connected by a refrigerant pipe 10 to form a circulation loop as shown in the figure. The refrigerant compressed by the compressor 1, for example, chlorofluorocarbon, is adiabatically compressed to produce the indoor heat exchanger 2
Inside, it condenses and liquefies while releasing the heat of condensation. This heat of condensation is released into the room from the outer surface of the indoor heat exchanger 2 and used for heating. The liquefied refrigerant is sent to the decompression mechanism 4, where it undergoes adiabatic expansion and the temperature drops. This refrigerant enters the outdoor heat exchanger 3, receives heat from the outside air, evaporates, and returns to the compressor 1 again. That is, the heat retained by the outside air was heated by the compressor and used for heating.

れている。Further, in JP-A-60-175976 and JP-A-58-78055, a heat storage material is stored in a main circuit of a refrigeration cycle, and a pipe connecting a four-way valve and an indoor heat exchanger is penetrated. The heat storage layer is provided in contact with the bottom of the compressor. Alternatively, it is disclosed that a metal hydride is disposed in contact with a lower portion of a compressor and the heat of the compressor, low pressure suction refrigerant and air are used as its cold heat source.

がある。The drawback of such an air conditioner is that the rising characteristics at the start of heating are poor, and sufficient heating cannot be performed due to insufficient warming power especially in the early morning. This is largely related to the large heat capacities of the compressor 1, the indoor heat exchanger 2, and the outdoor heat exchanger 3.
On the other hand, after a lapse of time from the operation of the compressor 1, the temperature becomes considerably high and a large amount of heat is radiated to the outside from the outer surface of the compressor 1 and is not effectively utilized. Further, if the compressor 1 becomes too hot, the internal windings may be burned or the bearing may be damaged.

It was a storage material, could not store the heat of the compressor, and required piping and valves.

The heat storage device 6 in this embodiment is a capsule type, and a latent heat storage material (for example, sodium thiosulfate having a melting point of 48 ° C., sodium acetate having a melting point of 56 ° C., etc.) is placed in the capsule. Between the compressor 1 and the heat storage device 6, a fan 5 capable of forward and reverse rotation is provided as shown in the figure. When the compressor 1 is at a high temperature, the fan 1 blows air from the compressor 1 to the heat storage device 6 as indicated by a solid arrow. Compressor 1
Is cooled by forced convection of air from its surface, improving the reliability of the coil winding and bearing inside. On the other hand, thereby, the warmed air enters the heat storage device 6 and is absorbed by the heat storage material. In the early morning, when the warming power of the air conditioner is insufficient, the fan 5 is rotated in the reverse direction, and the air is blown from the heat storage device 6 to the compressor 1 as indicated by the broken line arrow. The heat held by the heat storage material in the heat storage device 6 is transmitted to the compressor 1 via air, and the temperature of the refrigerant flowing therein rises. Therefore, the temperature of the indoor heat exchanger 2 also rises, and the warming power increases.
