(2) Heat storage operation: The refrigerant is discharged by the compressor 2, the water is heated by the heat storage heat exchanger 33, the refrigerant is condensed, and the refrigerant is evaporated by the air heat exchanger 3 and returns to the compressor 2. As a result, hot water accumulates in the middle portion of the three-layer heat storage tank 30. At this time, cold water or ice can be formed in the lower part by using the heat exchanger 34 for cold storage instead of the air heat exchanger 3 as an evaporator by the same means as the item (1). (3) Cold storage operation: The refrigerant is discharged by the compressor 2, the heat is radiated by the air heat exchanger 3, the refrigerant is condensed, the water is cooled by the heat exchanger 34 for cold storage, cold water or ice is produced, and the refrigerant is evaporated, Return to compressor 2. (4) Heating operation: Hot water is taken out from the heating socket 36 in the middle portion of the three-layer heat storage tank 30 and sent to the indoor unit 10 by the circulation pump 28 to heat the indoor air. (5) Cooling operation: Cold water is taken out from the cooling socket 37 at the bottom of the three-layer heat storage tank 30 and is sent to the indoor unit 10 by the circulation pump 28 to cool the air in the room. (6) Hot water: Hot water is discharged from the hot water outlet 41. Water is supplied from the water supply pipe 39 in an amount corresponding to the amount of water used.
