REFRIGERATING CYCLE

PURPOSE:To prevent a large quantity of liquid refrigerant from being sucked into a compressor at the time of starting by providing an accumulator heater. CONSTITUTION:A heater 16 for heating an accumulator 6 is provided, and the heater 16 is energized when a compressor 1 is stopped to heat the accumulator 6. Refrigerator is not condensed in the accumulator 6, and liquid refrigerant is not stored. When the compressor 1 is started, liquid and gas mixture refrigerant containing liquid refrigerant 18 is fed from an inlet pipe 10 into the accumulator 6. Then, it is rotated by a fairing plate 11, liquid and gas refrigerants are separated, the liquid refrigerant is stored in the accumulator 6 so that a large quantity of the liquid refrigerant is not sucked into the compressor 1. Thus, it can prevent the reliability of the compressor 1 from decreasing due to the large quantity of the liquid refrigerant.
