Purge system for closed-cycle absorption heat pumps

A high-efficiency, motorless purge system for closed-cycle absorption heat pumps, adapted for both absorption heat transformers and absorption chillers, using a series of valves to control the entry and exit of absorbent solution into a low-pressure, secondary absorption vessel. A small percentage of the total circulating solution is forced under pressure into the secondary absorption vessel via a spray nozzle, causing adiabatic absorption of absorbate vapor by the solution. Non-condensable gases accumulate in the secondary absorber until a certain vapor pressure is reached, upon which, gas, and possibly liquid, are transferred to an exhaust vessel having an exit vent for non-condensable gases. In an absorption chiller system, the secondary absorber has an internal heat exchanger to lower the temperature of the solution within, to facilitate the absorption process.

DETERMINATION DEVICE
