ABSTRACT A circuit for recovering refrigerant from a disabled refrigeration unit combines a vacuum pump, vapor pump or compressor in series with a compressor for drawing gaseous refrigerant from the disabled unit. The series arrangement of the vacuum source and the compressor provides approximately - 29 inches of mercury at the suction side of the vacuum source. A condenser in series with the compressor converts the gaseous refrigerant into a liquid refrigerant and a storage tank in series with the condenser receives liquid refrigerant from the condenser. In one preferred arrangement a valve system connected in series between the condenser and the storage tank allows the storage tank to be disconnected from the circuit without release of refrigerant from the tank to the atmosphere. The circuit may also include a coil in parallel with the condenser and the compressor and helically disposed around the storage tank for cooling the storage tank. A separator may be connected in series between the vacuum source and the compressor for removing impurities from the gaseous refrigerant and another coil connected in series between the compressor and the condenser and helically disposed around the separator may be used to heat the separator. In addition to the gaseous refrigerant recovery line, a liquid refrigerant line in series between the unit and the storage tank drains liquid refrigerant from the unit into the storage tank prior to operation of the gaseous refrigerant recovery line.
