Abstract: A refrigerant recycle and reclaim system includes two liquid refrigerant receivers; a low and a high pressure compressor in fluid communication with each other, each having their own oil separator; a condenser; filter driers; a particular arrangement of check and block valves and a high pressure float proximate the receivers; suction gas cooling components; and auxiliary devices. The suction gas cooling components include an expansion valve, a filter drier, a solenoid valve, and a mixer with sensor. The auxiliary devices include level switches, relief valves, purity sensors, and solenoids. The check and block valves, in combination with the high pressure float, automatically select which liquid receiver the refrigerant will therein be contained. The cooling components serve to lower the temperature of heat-intensive suction gases before entering into the low pressure compressor. The auxiliary devices help serve to continuously recycle refrigerants up to 275 PSIG.

Abstract: A purge processor for purging air and other noncondensibles from refrigeration systems or refrigeration handling systems includes: an inlet gas connector for receiving a gaseous mixture of noncondensibles and refrigerant; a first and second refrigerant receiver; a compressor; a condenser; and a differential pressure switch connected to a solenoid valve for automatically purging a predetermined percentage by volume of refrigerant. For low pressure refrigerant, a back pressure regulator maintains the second refrigerant receiver at a colder temperature than the first. For high pressure refrigerant, an additional compressor and condenser maintains the second refrigerant receiver at a colder temperature than the first. The present invention can continuously separate refrigerant and automatically purge an exhaust known to have less than 1% by volume of refrigerant.

Abstract: A refrigerant and transfer system has a vapor suction inlet connector to introduce refrigerant from a refrigerant line of a refrigerant system under repair containing refrigerant in vapor form to an input end of a first fluid path which pumps the refrigerant to its output end. The first fluid path has a filter and drying stage, a high pressure compressor, and an oil separator to purify the refrigerant passing therethrough. The refrigerant is then passed to a condenser and stored in a receiver tank of the receiver section. If the refrigerant line of the refrigerant system under repair contains a refrigerant in liquid form, then the refrigerant line should be connected to a liquid refrigerant connector of the refrigerant processing and transferring system. The refrigerant is then stored in a receiver tank of the receiver section. The refrigerant can be further processed by transferring the refrigerant from one receiver tank to another using the first fluid path.
