A METHOD OF OPERATING A REFRIGERATION SYSTEM INCLUDING A STEAM DRIVEN TURBOCOMPRESSOR FOR COMPRESSING A REFRIGERANT HAVING A VAPOR POINT LOWER THAN WATER AND A STEAM CONDENSER, COMPRISING THE STEPS OF, SUPPLYING STEAM TO THE TURBINE FOR DRIVING THE TURBOCOMPRESSOR, PASSING THE STEAM DISCHARGED FROM THE TURBINE INTO THE STEAM CONDENSER, REDUCING THE TURBOCOMPRESSOR OUTPUT BELOW ITS MAXIMUM OUTPUT TO REDUCE THE COOLING CAPACITY OF THE SYSTEM BY PASSING REFRIGERANT VAPOR INTO THE STEAM CONDENSER TO INCREASE THE TURBINE DISCHARGE PRESSURE, AND REGULATING THE TURBINE DISCHARGE PRESSURE TO VARY THE TURBOCOMPRESSOR OUTPUT AND THEREBY THE COOLING CAPACITY OF THE SYSTEM BY REGULATING THE QUANTITY OF SAID REFRIGERANT VAPOR IN SAID STEAM CONDENSER.
