  • Enhanced refrigerant recovery system
    Patent number: 5910160
    Abstract: A refrigerant recovery system for use in connection with a refrigeration system having an evaporator, a compressor, and a condenser, and a purge unit connected to the condenser for receiving gaseous refrigerant and non-condensable gases from the condenser. A tank connects to the purge unit by a line for receiving purged gaseous refrigerant and purged non-condensable gases from the purge unit. The tank contains adsorbent material for recovering the purged gaseous refrigerant from the purged non-condensable gases. The system includes means for determining when a predetermined amount of purged gaseous refrigerant is received by the tank and means for controlling the flow of fluids to and from the tank.
