HEAT PUMP HOT WATER SUPPLY APPARATUS

PROBLEM TO BE SOLVED: To miniaturize a hot water supply apparatus in consideration of workability or the like and to prevent freezing of defrosting water of evaporators. SOLUTION: This heat pump hot water supply apparatus is constituted by enclosing inside a casing, compressors 102a, b for compressing a refrigerant; a water-refrigerant heat exchanger 103 for exchanging heat between a refrigerant passage where the refrigerant compressed by the compressors flows, and a water passage where water supplied from a water supply circuit flows; a pressure reducing device 104 for reducing the pressure of the refrigerant lowered in temperature by the water-refrigerant heat exchanger; the evaporators 105a, b for evaporating the refrigerant reduced in pressure by the pressure reducing device, to return to the compressors; and a hot water storage tank 103 communicating with a hot water supply pipe for supplying a hot water supply port with hot water heated by the water-refrigerant heat exchanger. The compressors are arranged in a storage chamber 10 partitioned in a space below the evaporators, and a pan 13 for receiving the defrosting water of the evaporators is used as a part of members for partitioning the storage chamber.
