PROBLEM TO BE SOLVED: To start a freezing preventing operation after an indoor side heat exchanger is actually frosted. SOLUTION: In the refrigerator comprising a compressor 1, an outdoor side heat exchanger 3 operated as a condenser when cooled or operated as an evaporator when heated, a pressure reducing mechanism 4, and an indoor side heat exchanger 5 operated as an evaporator when cooled or operated as a condenser when heated, when a mean cooling integrated capability Qr when cooled is lowered, a control means (controller 17) for starting a freezing preventing operation for stopping an operation of the compressor 1 is attached, and when the exchanger 5 is frosted to lower the capability Qr, the freezing preventing operation for stopping the compressor 1 is started. |
