Abstract

Abstract of the Disclosure A system for purification of refrigerant within a storage container includes a filter/dryer for removing contaminants' from refrigerant passing therethrough, and a refrigerant pump connected to the storage container to circulate refrigerant in a closed path from the container through the filter/dryer and return the refrigerant to the container. The system configuration is such that the refrigerant is in liquid phase in at least a portion of the closed path. A pressure-differential valve has an inlet coupled to a purge port on the container for receiving air captured within the container.
Container air pressure at the valve inlet is fed to one side of a flexible diaphragm. Circulating liquid refrigerant is passed in heat transfer contact with a sealed enclosure containing liquid refrigerant, so that the refrigerant within the enclosure is at saturation pressure and acts on the opposing side of the diaphragm in conjunction with a valve spring. The diaphragm is coupled to a valve element that lifts from a valve seat to connect the valve inlet to an outlet, and thereby vent air from within the storage container, whenever container air pressure exceeds refrigerant saturation pressure by a threshold that is determined in part by the valve spring.
