Abstract
An absorption system includes a generator, a condenser, an evaporator, and an absorber configured to circulate a solution of an absorber and a refrigerant. A purge system removes a non-condensable gas from the absorber. The purge system includes a first pump to remove the solution from the absorber, a connection to remove the refrigerant vapor and the non-condensable gas from a low pressure region of the absorption system, an eductor to receive and mix the solution, a separator to receive the solution and remove the non-condensable gas from it, a tank to receive the non-condensable gas from the separator, a controller to monitor a pressure level of the tank, and a second pump to remove the non-condensable gas from the tank in response to the monitored pressure level in the tank being greater than a predetermined pressure level.
