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.
