摘要： PURPOSE:To raise the temperature of hot water supply by heating the hot water simultaneously by a heat pump and exhaust heat, and, in addition to that, by heating the water in an exhaust heat water heater by operating the engine only after the compressor of the heat pump is stopped. CONSTITUTION:When the heating is started for hot water supply at T1, since the coolant temperature TC in or around a coolant temperature sensor 14 of an engine 1 and a condenser 4, the water is heated by a heat pump refrigerant circuit A and a waste heat recovering circuit B. When the refrigerant temperature in the condenser 4 becomes a saturated temperature TC2 under the allowable refrigerant pressure at T2, an electromagnetic clutch 2 is disengaged to stop the compressor 3 and stop heating the water by the heat pump refrigerant circuit A. From this time on, only the engine 1 is operated, and the water is heated by the exhaust heat of the engine operated in the idling mode. In this manner, the hot water is heated from 60 deg.C to 85 deg.C.
