REFRIGERATOR

摘要

A refrigerator, comprising a three-way delivery valve (8) allowing the delivery side of a compressor (1) to communicate with at least one of a hot water heat exchanger (3) and an air heat exchanger (6) and a three-way suction valve (9) allowing the suction side of the compressor (1) to communicate with at least one of the air heat exchanger (6) and a cool water heat exchanger (4). When a primarily cooling operation is performed, the delivery side of the compressor (1) is allowed to communicate with the hot water heat exchanger (3) and the air heat exchanger (6), and the suction side of the compressor (1) is allowed to communicate with the cool water heat exchanger (4) to function the air heat exchanger (6) as a condenser. A control device (19) determines the target pressure value (Ps) of refrigerant in the air heat exchanger (6) according to the target temperature value (Ts) of water heated by the hot water heat exchanger (3), and controls a blower (16) blowing air to the air heat exchanger (6) so that the detected value (Pm) of a pressure sensor (18) detecting a pressure in the air heat exchanger (6) nears the target pressure value (Ps). Thus, a condensing pressure in the air heat exchanger (6) can be prevented from being remarkably lowered to lower the flooded phenomenon of the refrigerant.
