Patent ID: 7891202

Claim:
An absorption system, comprising: a generator, a condenser, an evaporator, and an absorber configured to circulate a solution of an absorber material and a refrigerant; the absorber configured to contain the solution, a refrigerant vapor, and a non-condensable gas; and a purge system to remove the non-condensable gas from the absorber, the purge system comprising: a first pump configured to remove the solution from the absorber; a connection configured to remove the refrigerant vapor and the non-condensable gas from a low pressure region of the absorption system; an eductor configured to receive and mix the solution removed by the first pump and the refrigerant vapor and the non-condensable gas removed by the connection; a separator configured to receive the solution, the refrigerant vapor, and the non-condensable gas from the eductor, the separator being configured to remove the non-condensable gas from the solution and the refrigerant vapor; a tank configured to receive the non-condensable gas from the separator; a controller configured to monitor a pressure level of the tank; and a second pump configured to remove the non-condensable gas from the tank in response to the monitored pressure level being greater than a predetermined pressure level.
