A refrigerating cycle provided with a compressor (20), a water cooling cycle formed by a water-refrigerant heat exchanger (52), a radiator (36) switched by flow path switch valves (46, 48), and a heat storage tank (50), and a water heating cycle formed by an engine (14), a heater core (38) and the heat storage tank (50). Accordingly, when the engine is driven, heat for cooling or heating is accumulated in the heat storage tank (50) by the water cooling cycle or the water heating cycle, and when the engine (14) is stopped, heat accumulated in the heat storage tank (50) is used to effect cooling or heating.
