Abstract: A high efficiency, self-modulating refrigeration system has three principal parts, including (1) a compression refrigeration circuit, (2) an absorption refrigeration circuit coupled in cascade with the compression circuit, and (3) an engine or prime mover/electric generator combination, with the electric generator supplying power to the compressors, pumps, fans and other auxiliary equipment, of the refrigeration circuits, and the waste heat from the prime mover or engine being supplied to the still, or reboilers associated with the absorption refrigeration circuit. Ammonia is used in the absorption circuit, and ammonia or Freon is preferably used in the compression circuit. For retrofitting of compression systems, the existing compression and other equipment may be retained, and employed when servicing or repairing the absorption circuit, or engine generator. Multiple staging may be employed, and the various circuits may be intercoupled from a heat exchange standpoint at several points in the circuits.
