ABSTRACT:
A refrigerant-compression temperature regulation system providing for suction gas cooling includes: (a) a compressor for compressing the refrigerant in vapor and gaseous phase; (b) a condenser downstream from the compressor for condensing the compressed refrigerant to liquid phase; (c) a first valve downstream from the condenser for creating a predetermined pressure drop; (d) a first evaporator downstream from the first valve for transferring heat between a load and the refrigerant; (e) a suction gas return line leading from the first evaporator to the compressor for returning heated refrigerant to a suction inlet of the compressor; and, (f) a first indirect heat exchanger having a suction gas cooling path from the first valve to upstream of the first evaporator, the first indirect heat exchanger for passively transferring heat from the gas and vapor phase refrigerant in the suction gas return line to the vapor phase refrigerant entering the first evaporator.
