Abstract
A vapor compression cooling system operating at a pressure ratio of about 4 or less includes a compressor 10 having a inlet 12 and an outlet 14, a countercurrent condenser 20 connected to the compressor outlet 14 and a countercurrent evaporator 52 connected to the compressor inlet 12. A first heat exchanger 30 interconnects the condenser 20 and a second heat exchanger 38 which in turn is connected to the evaporator 52 via an expansion valve 46. The heat exchangers 30 and 38 have countercurrent flow paths and provide a path including an expansion valve 48 to the compressor inlet 12.
