ABSTRACT:
Refrigerant recovery and purification system optionally capable of drawing a nearly full vacuum on the system to be evacuated and having multi-port valve means for setting to different configurations for different refrigerant processing cycles; e.g., evacuation, deep vacuum, recovery, purification cycle, refrigerant charging, and oil charging, etc. Virgin refrigerant can be inputted from commercial cylinders or from refrigerant cans via a can manifold. Major components comprise: Inlet/outlet means 10, suction accumulator means 20, low-side purifying means (filter dryer) 30, compressor means 40, secondary coil means 70, purifying means (highside) 90, pump-down manifold means 100, storage means 120, oil injection means 140, virgin refrigerant supply means 170 and 180, vacuum pump means 200, and circulation control means 240.
