The invention provides a turbine refrigerator, which guarantees the oil-recycling function of an ejector through the pressure control of gas for the driving of the ejector and can maintain the stable operation of a refrigerator. The turbine refrigerator is provided with an evaporator (3) which extracts heat from cold water so as to enable refrigerant to be evaporated and achieve a refrigeration effect; a turbine compressor (1) which compresses the refrigerant through an impeller; a condenser (2) which enables the compressed refrigerant gas to be cooled and condensed through cooling water; an ejector (20) which enables the refrigerant gas discharged from the turbine compressor (1) to serve as driving gas, thereby absorbing the refrigerant, which stays in the evaporator (3) and contains oil, back to an oil tank of the compressor (1); a control valve which is disposed on a refrigerant supply distribution pipe (5BP) which supplies the refrigerant gas to the ejector (20) from the compressor (1) and controls the pressure of the refrigerant gas flowing in the refrigerant supply distribution pipe (5BP); and a control device (10) which controls the opening degree of the control valve (21). |
