ABSTRACT:
A refrigerant recycling system (10) has a compressor (12) and identical first and second drier/separators (18, 20). Refrigerant material to be reclaimed is drawn into an inlet (22) of the first drier/separator, in which lubricant is separated from refrigerant vapor. After the lubricant is removed, the refrigerant vapor is filtered as it passes through a screen (80), a bed of molecular sieve material (82), and a fibrous pad (84). After passing through the first drier/separator, the refrigerant enters the compressor in which clean lubricant material is introduced to enable the compressor to operate effectively. From the compressor, the refrigerant vapor and clean lubricant passes through the second drier/separator wherein the clean lubricant is removed and the refrigerant vapor is again filtered. The twice filtered vapor is then passed to a condenser (44) in which it is condensed to a liquid. The clean refrigerant liquid is delivered from the reclamation system cleansed of impurities.
