Combustion-powered compound refrigeration system
This patent describes an improved refrigeration system. It comprises a refrigerant vapor compressor driven by a prime mover powered by the combustion of a fluid fuel, a condenser connected to the compressor to condense the hot compressed refrigerant vapor, a heat exchanger connected to receive the condensed refrigerant and to effect subcooling thereof, a pressure-reducing valve connected for the expansion of the subcooled refrigerant and for the discharge of the expanded refrigerant into an evaporator equipped with heat transfer surface for the recovery of refrigeration from the evaporator by a fluid passed in contact with the heat transfer surface. The evaporator being connected to pass refrigerant vapor therefrom back to the compressor, and an ammonia absorption refrigeration unit connected to utilize waste heat of the hot exhaust gases from the prime mover and further connected to pass liquid ammonia through an ammonia subcooler.
