<P>PROBLEM TO BE SOLVED: To provide a heat pump water heater having a structure in which a water-refrigerant heat exchanger is disposed in a wind path chamber capable of reducing ventilation resistance caused by the water-refrigerant heat exchanger by disposing the water-refrigerant heat exchanger in a space not obstructing airflow flowing between a fan and an air heat exchanger and improving capacity of the air heat exchanger. <P>SOLUTION: This heat pump water heater includes a compressor 2, the water-refrigerant heat exchanger 3, a refrigerant circuit in which an expansion valve 4 and the air heat exchanger 5 are sequentially connected by pipes, the fan 6 through which air passes to the air heat exchanger 5, a box body 1 for storing the refrigerant circuit and the fan 6 thereinside, and a separator for separating the box body 1 into a machine chamber 20 and the wind path chamber 30. The compressor 2 and the expansion valve 4 are disposed in the machine chamber 20, and the water-refrigerant heat exchanger 3, the air heat exchanger 5, the fan 6, and a bellmouth 41a forming a wind path of the fan 6 are disposed in the wind path chamber 30, wherein the water-refrigerant heat exchanger 3 is disposed on the outer periphery of the bellmouth 41a. <P>COPYRIGHT: (C)2010,JPO&INPIT |
