ABSTRACT:
A refrigerator includes a compressor compressing a refrigerant, a first liquid heat exchanger performing heat exchange between the refrigerant and a first liquid heat medium, an expander expanding the refrigerant, a second liquid heat exchanger performing heat exchange between the refrigerant and a second liquid heat medium, an air heat exchanger performing heat exchange between the refrigerant and air, a blower sending air to the air heat exchanger, a refrigerant flow rate regulator regulating a flow rate of the refrigerant of the first liquid heat exchanger, the second liquid heat exchanger and the air heat exchanger, a pressure sensor detecting a pressure value of the refrigerant of the air heat exchanger, a target pressure value setter setting a target pressure value of the refrigerant of the air heat exchanger in accordance with a target temperature value of the first liquid heat medium, and a blower controller controlling the blower so that the detection value of the pressure sensor becomes the target pressure value.
