SUCTION ACCUMULATOR HAVING HEAT EXCHANGER

摘要

A heat exchanger in a suction accumulator for the compressor of a refrigeration system wherein the suction accumulator comprises a storage vessel having a liquid and gaseous refrigerant inlet, and means within the vessel defining a fluid passageway for separating the gaseous and liquid components and conducting the gaseous component and a controlled amount of liquid out of the storage vessel to the inlet of the compressor. This fluid passageway may comprise a generally U-shaped conduit or, alternatively, a U-shaped flume formed by a vertical weir member. The heat exchanger comprises a jacket disposed over at least a portion of the surface of the gaseous refrigerant conduit or weir member and is spaced therefrom so as to form a second fluid passageway, which is sealed from the gaseous refrigerant passageway and the interior of the vessel. An inlet and outlet lead from the second fluid passageway out of the storage vessel.
