Abstract
A hydraulic refrigeration system (10) employs as a preferred embodiment a hydrocarbon fluid as a refrigerant in combination with a non-miscible carrier fluid. A plurality of stages (110, 210, 310) of hydraulic refrigeration system (10) may be used by conveying the segregated refrigerant vapor from each stage to the entrainer (240, 340) of the next succeeding stage (210, 310). The liquid refrigerant of the last stage (310) is conveyed to an evaporator (416), which may be remotely located. The outflow of the evaporator (416) is conveyed to the entrainer (140) of the first stage (110). Second and succeeding stages include a non-miscible carrier fluid return line (268) connected to the respective separators (214, 314) for returning the non-miscible carrier fluid to the separator (114) of the first stage (110).
