  • Patent number: 5671605
    Abstract: A refrigerant recovery system for recovering refrigerant from a cooling system is disclosed. A compressor (60) is provided having an oil drain outlet (66). An oil separator (50) is also provided for receiving incoming refrigerant before the refrigerant is drawn into the compressor (60). The oil separator has a helical coil (90) disposed in a heat exchange relationship with the oil separator (50) for receiving the refrigerant after the refrigerant is compressed by the compressor (60) and thereby cooling the refrigerant. A condenser coil (92) is also provided for receiving the refrigerant after the refrigerant has passed through the helical coil (90) and further cooling the refrigerant, causing it to condense. An aluminum base (100) is provided for dissipating heat from the condenser coil (92) and the oil separator (50) since the condenser coil (92) and the oil separator (50) are mounted directly on the aluminum base (100).
