ABSTRACT:
Apparatus for recovering compressible refrigerant from a refrigeration system, purifying the recovered refrigerant, and testing the purity of the recovered purified refrigerant which includes a compressor, a condenser, a refrigerant storage means and a refrigerant purification means all connected in serial fluid communication. Means are provided for operably supporting a refrigerant purity sampling system in parallel fluid flow relationship with the compressor. The system is adapted to operate in a refrigerant recovery mode wherein refrigerant is withdrawn from a refrigeration system being serviced. This system is also capable of operating in a refrigerant purification mode wherein the refrigerant withdrawn from the refrigeration system is continually circulated through the circuit to provide multiple passes through the purification system. And a further refrigerant purity test mode of operation is provided wherein refrigerant from the storage cylinder is passed directly to a refrigerant purity sampling tube. This mode passes the refrigerant purifying means to thereby assure that the refrigerant being tested for purity is representative of the refrigerant stored in the storage container.
