Abstract: PURPOSE:To always supply a refrigerant in a state of a vapor phase into a compressor in a refrigerating system. CONSTITUTION:A refrigerant condensed in an evaporator 9 and a suction pipe 11 when a compressor 1 is stopped is to pass through a suction line 11 and enter a compressor machine part 1 when the compressor 1 is started. In order to prevent this behavior, the refrigerant is made to flow through a bypass piping 13 for several minutes after the start by a selector valve 15 which gears in delay with the compressor 1. Thereby a refrigerating machine oil 12 and the refrigerant exchange heat with each other and the refrigerant is put in a state of a vapor phase and supplied to a compressing part 2 in the compressor 1. After several minutes from the start, supply of the refrigerant to the bypass piping 13 is stopped and supply thereof to a main piping is started by a solenoid operated three-way valve 15.
