Abstract:
A purging device for a system accumulating condensable and non-condensable gases, the purging device comprising:a purge tank; an inlet connection to the purge tank for receiving the condensable and non-condensable gases from the system and directing said gases into the purge tank; refrigeration means associated with the purge tank for condensing the condensable gases into a condensed form and including a serially linked refrigeration system including a compressor, an evaporator, an expansion device and a condenser and wherein the evaporator comprises a heat exchanger located within the purge tank; header space in the purge tank for accumulating the non-condensable gases; a first outlet connection for returning the condensed gases from the purge tank to the system; a second outlet for controllably removing the accumulated non-condensable gases from the header space; and a baffle in the purge tank and affixed to the evaporator for providing a controlled flow space for the condensable and non-condensable gases and providing a quiet zone in the header space.
