摘要：A servicing device is shown for recovering and charging refrigerant in a coolingsystem of the type having a compressor for circulating compressible refrigerant in aclosed, pressurized system between a condenser and an evaporator to provide a coolingeffect. The servicing device includes a storage container which has a fill port which isadapted to be connected by a fluid conduit to the closed, pressurized system beingserviced. Heat exchange coils located within the container are cooled by a heat exchangesystem to create a low pressure atmosphere within the container and draw refrigerantfrom the closed, pressurized system into the container. The heat pump system hasreversible valves to reverse the flow of auxiliary refrigerant being circulated through thesystem. When the refrigerant circulation is reversed, the heat exchange coils locatedwithin the storage container heats the container to create a relatively higher pressureatmosphere to charge refrigerant from the storage container into the closed,pressurized system.
