Abstract
In a refrigerant cycle system, a control unit controls both a refrigerant amount discharged from a compressor and an opening degree of a pressure control valve so that theoretical efficiency of a super-critical refrigerant cycle and efficiency of the compressor are improved. Therefore, the effective coefficient of performance of the refrigerant cycle is improved, while necessary capacity of components of the refrigerant cycle is obtained.
