Abstract
A refrigeration system including a compressor, a condenser, an expansion valve and an evaporator with controls and interconnections to provide a system operating in a vapor refrigeration cycle containing a refrigerant or combination thereof selected from a group of low vapor pressure refrigerants having boiling points anywhere from about 10 degrees F. to 83 degrees F. and the compressor comprising an open system constrained rotary vane compressor having a ratio Q/D of cooling capacity per unit of displacement anywhere in the range from about 8,000 to 30,000 FT-LB per HR/FT.sup.3 per HR determined by the refrigerant or combination thereof in the system and according to a specified formula.
