PROBLEM TO BE SOLVED: To unfailingly obtain heat for melting frost adhering to a heat exchanger for heat absorption.SOLUTION: A freezing cycle device includes: a high pressure side heat exchanger 15 which causes a refrigerant discharged from a compressor 21 and a first heat medium to exchange heat to heat the first heat medium; a low pressure side heat exchanger 14 which causes the refrigerant decompressed by decompression means 22 and a second heat medium to exchange heat to cool the second heat medium; a heat exchanger 13 for heat absorption which causes the second heat medium cooled by the low pressure side heat exchanger 14 and air to exchange heat to cool the air; introduction means 42, 43 which introduce heat quantity of the first heat medium heated by the high pressure side heat exchanger 15 into the heat exchanger 13 for the heat absorption; and heat medium temperature adjustment means which determines whether or not frost adheres to the heat exchanger 13 for the heat absorption and rises a temperature of the first heat medium heated by the high pressure side heat exchanger 15 when determining that the frost adheres to the heat exchanger 13 for the heat absorption. |
