ABSTRACT:
In refrigeration systems wherein the refrigerant compressor is driven by a prime mover powered by combustion of a fluid fuel, a notable saving in fuel consumption is achieved by utilizing waste heat in the hot exhaust gases from the prime mover in an ammonia absorption refrigeration unit to produce refrigeration in the form of liquid ammonia. Subcooled liquid ammonia is used to subcool the compressed and condensed refrigerant prior to its expansion and evaporation to produce saleable refrigeration. This compound refrigeration system is economically attractive for producing large tonnage refrigeration particularly when a combustion turbine coupled to a centrifugal compressor is used.
