CONSTITUTION:A refrigerant gas with a high temperature which is discharged from a compressor 1 during nighttime passes through a 4-way valve 2, and is condensed by radiation by an outdoor side heat-exchanger 7, and passes through a first solenoid valve 12 being opened, and the pressure is reduced by an expanding mechanism 4d being connected to a heat accumulating tank 6, and heat is accumulated in the heat accumulating tank 6, and the refrigerant gas returns to the compressor 1 through a third solenoid valve 14 being opened. Then, during daytime, the refrigerant gas with a high temperature which is discharged from the compressor 1 flows into the heat accumulating tank 6 through a second solenoid valve 13 being opened, is condensed by radiation, and the pressure is reduced by a plurality of expanding mechanisms 3a-3c after passing through the expanding mechanism 4d. Then, the refrigerant gas returns to the compressor 1 through forth solenoid valve 15 and the 4-way valve 2. Therefore, the discharging pressure of the compressor 1 is reduced, and an extremely efficient operation condition is provided.
