Abstract
An absorption refrigeration system having an absorber, a generator, and a refrigeration solution pump which flows relatively dilute refrigeration solution received from the absorber to the generator includes a novel purge subsystem which purges un-wanted, non-condensed gases along with some refrigerant vapor from the absorber and flows such gases to the pump inlet for subsequent flow to the generator at system operating pressures substantially greater than atmospheric pressure. The so-flowed gases are separated from the refrigerant in the generator, are isolated in a collector unit, and afterwards periodically either manually or automatically vented from the collector unit to the atmosphere at the system high side operating pressure.
