ABSTRACT:
A system for refrigerant and recovery and processing includes a hollow fluid-tight pressure vessel having a fluid input; a hollow annular jacket having its inner surface in thermal communication with the pressure vessel, the jacket having a polar axis in substantial alignment with the gravity vector, and the jacket having a liquid accumulator at the bottom thereof. The jacket is provided with an input in liquid communication with the refrigeration system to be vented during a recovery process, such input line in fluid communication with the pressure vessel during reprocessing of the refrigerant. The input from the refrigerant line is further provided with a liquid expansion element for selectively increasing the volume of fluid flowing from the vessel, or from the refrigerant system to be vented. A condenser is in fluid communication with the output of the pressure vessel. Resultingly, the temperature of the vessel will be lowered by virtue of its thermal communication with the jacket, enhancing the efficiency of the condenser and, consequently, of the processing system.
