Abstract

An outdoor unit includes an air heat exchanger; a compressor; a water heat exchanger; an expansion valve; a fan that moves air outside the outdoor unit into the air heat exchanger; a motor that rotates the fan; a power device used for driving the compressor; a heat sink located in a space that is an extension portion beyond the air heat exchanger, of a channel of air moved by rotation of the fan during heating of the water from outside the outdoor unit into the air heat exchanger, where the heat sink dissipates heat generated by the power device during driving of the compressor; and a control unit that provides control, upon completion of a water heating operation, to drive the compressor, to open the expansion valve, and to rotate the fan in the same direction as the rotation direction of the fan during heating of the water.

Claims

exact text as granted — not AI-modified
1 . (canceled) 
     
     
         2 . An outdoor unit of a heat-pump hot water dispenser, the outdoor unit comprising:
 an air heat exchanger to exchange heat between air outside the outdoor unit and a refrigerant;   a compressor to compress the refrigerant flowed out of the air heat exchanger;   a water heat exchanger to exchange heat between the refrigerant flowed out of the compressor and water;   an expansion valve to reduce a pressure of the refrigerant flowed out of the water heat exchanger;   a fan to move air outside the outdoor unit into the air heat exchanger;   a motor to rotate the fan;   a power device used for driving the compressor, the expansion valve, and the motor;   a heat sink located in a space that is an extension portion beyond the air heat exchanger, of a channel of air moved by rotation of the fan during heating of the water from outside the outdoor unit into the air heat exchanger, the heat sink dissipating heat generated by the power device during driving of the compressor; and   a controller to provide control, upon completion of operation of heating of the water, to rotate the fan in a direction opposite to a rotation direction of the fan during heating of the water.
