  • Patent number: 9989285
    Abstract: A purging apparatus for removing a non-condensable gas from a refrigeration system is described and which includes a low temperature liquid refrigerant storage tank for enclosing refrigerant, which is supplied by the refrigeration system, and a condenser having a main body, which lies in conductive heat transferring relation relative to an exterior facing surface of the storage tank and progressively to the low temperature liquid refrigerant within, and wherein the condenser, is maintained at a reduced temperature by the low temperature liquid refrigerant enclosed within the storage tank, and wherein foul gas generated by the refrigeration system is processed by the condenser in a manner so as to remove non-condensed refrigerant, and return the condensed refrigerant to the storage tank while releasing non-condensable gases to the ambient environment.
