REFRIGERATOR WITH SUBCOOLING FLOW CONTROL VALVE

摘要

A household type refrigerator has a refrigerationsystem including a subcooling flow control valve placedbetween the outlet of the condenser and the inlet to thecapillary tube. The subcooling flow control valve utilizesa sealed capsule of refrigerant which operates to open andclose a valve to modulate the flow from the condenser to thecapillary tube to insure only that a subcooled liquid entersthe capillary. The valve is mounted vertically next to thecompressor and has the inlet line to the valve secured in heatconducting contact to the return line to the compressor forfaster opening and closing response while the discharge sideof the valve has a chamber filled with a plug to minimize thevolume of refrigerant remaining between the closed valve andthe entrance to the capillary when the compressor is on theoff cycle.
