Service station for refrigeration equipment Refrigerant reclamation and charging unit Refrigerant recovery, purification and recharging system Open cycle cooled refrigerant recovery apparatus Refrigerant recovery and purification system Controls are provided for shutting down the cold side of the heat exchanger and the oil separator while the chill tank, filter-dryer, cooling coil, compressor and condenser continue to be active. Liquid refrigerant flows from the bottom of the chill tank through a filter-dryer, an expansion device, converting it to gas, through a cooling coil, submerged in liquid refrigerant in the chill tank, into the stream exiting the oil separator and back to the compressor. The gaseous refrigerant is passed from the oil separator through the compressor, the hot side of the heat exchanger, a condenser and into the chill tank in a liquid state. The flow of the stream is abruptly interrupted to separate oil from refrigerant. Refrigerant to be reclaimed is drawn through the cold side of the heat exchanger, converted to a gas which is discharged into the oil separator where the gas is directed upwardly in an expanding stream. A refrigerant reclaim system includes a compressor, a heat exchanger, an oil separator, a condenser, a chill tank, a filter-dryer and a cooling coil in the chill tank.
