ABSTRACT:
Multiple refrigeration systems, each with refrigerants having a different boiling point, are connected in series to provide successively lower temperatures. Following compression and heat rejection, the refrigerant mixture is cooled by heat exchange with refrigerant returning to the compressor. Gas and liquid phases are separated and the gas is cooled further by heat exchange with mixture returning to the compressor. System capacity is controlled by throttling the compressor suction.
