Abstract
PURPOSE: To eliminate a liquid compression or foaming in a compressor at the time of starting by reducing a circulating amount of refrigerant by storing the refrigerant circulating through a deep freezer immediately before stopping the compressor in a refrigerant tank, and reducing a liquid refrigerant amount staying in the compressor at the time of stopping. CONSTITUTION: In the deep freezer, at the time of a heating operation, refrigerant compressed by a rotary compressor 1 is guided to an indoor side heat exchanger 3, heat exchanged with the air, condensed to be liquefied to conduct the heating operation. Liquid refrigerant is pressure reduced by a hydraulic unit 4, vaporized by an outdoor side heat exchanger 5, and returned to the compressor 1 via a four-way switching valve 2. In the case of stopping the compressor 1, a first valve 10 is opened before stopping the compressor 1 by a controller 12, compressed refrigerant is stored in a refrigerant tank 7, and controlled to be closed after a predetermined time. Thus, the circulating refrigerant amount is reduced. The compressor 1 is stopped after the circulating refrigerant amount in a refrigerating cycle is reduced. Thus, at the time of stopping, the refrigerant amount stayed in the compressor is reduced, and at the time of starting, liquid compression or foaming is eliminated.
