Abstract
An absorption refrigeration unit having a purge system that will sense when the discharge pressure of the solution pump becomes subatmospheric and will automatically increase the speed of the pump to bring the discharge pressure up to a desired level above atmospheric pressure so that a purging cycle can be achieved. The system further monitors the generation solution level and interrupts the purging cycle in the event the solution reaches an undesirable level.
