Abstract:
1. A refrigerator comprising: 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.
