Abstract

A refrigeration cycle system for cooling of a medium to be cooled, comprising refrigerant compressor (3) for compressing of the refrigerant after cooling of a medium to be cooled; condenser (6) for condensing of the refrigerant having been compressed by the refrigerant compressor (3); uniaxial gas turbine (27) directly connected to the refrigerant compressor (3); return flow channel (12) connecting the downstream side of the condenser (6) with the inlet of the refrigerant compressor (3); and throttle valve (13) for controlling of the flow rate through the return flow channel (12). Accordingly, not only can the power required at the start-up of the refrigerant compressor be reduced but also there can be attained stabilization of the start-up of the refrigerant compressor in the employment of the uniaxial gas turbine as driving source.
