ABSTRACT:
A refrigeration/cooling system including a compressor (12, 14, 16, 18) having an inlet (54) and an outlet (20), a countercurrent condenser (24) connected to the compressor outlet (20) and an countercurrent evaporator (30) connected to the compressor inlet (54). A heat exchanger (36) interconnects the condensor (24) and the evaporator (30). A first throttling valve (34) is interposed between the heat exchanger (36) and the evaporator (30) and a second throttling valve (64) is located in the system downstream of the condenser (24) and upstream of the evaporator (30) for providing an at least partially expanded refrigerant to the heat exchanger (36). A refrigerant return (50) interconnects the heat exchanger (36) and a portion of the compressor (16) for returning the partially expanded refrigerant to the compressor.
