摘要
PURPOSE: A heat pump hot water heater is provided to improve the efficiency of heating by transferring a hot refrigerant to a water-refrigerant heat exchanger and using directly-heat-exchanged hot water in the water-refrigerant heat exchanger. CONSTITUTION: A heat pump hot water heater comprises a water-refrigerant heat exchanger(6) supplied with the hot refrigerant discharged from a compressor(1a), a decompressing unit(4a) for decompressing the heat-exchanged refrigerant, a heat pump cycle sequentially connected with an evaporator(2a), a decompressing valve for decompressing the supplied water, a hot water circuit having a water-proportional valve for controlling the outflow of hot water, a water-refrigerant heat exchanger(8) for heating, and a hot water heating circuit for circulating the heated water through a heating instrument.
