ABSTRACT:
A compressor is prevented from the problem of seizure at start-up even when return of lubricant to the compressor is delayed. In such a refrigerant cycle, a bypass passage bypasses an expansion member and an evaporator. The bypass passage opens for a predetermined time when the compressor starts. The predetermined time is dependent upon external temperature, the compressor speed, compressor capacity, etc.
