ABSTRACT:
A refrigerant recovery and purification system employs a centrifugal separator connected to a disabled automotive air conditioning system and connects a slack-sided accumulator to a reclaim condenser chamber. Oil and contaminants are separated by centrifugal action from the incoming refrigerant. Condensing of reclaimed refrigerant vapor in a condenser produces a vacuum pressure causing vapor to flow from the slack-sided accumulator. A conventional refrigeration system supplies refrigerant to a first evaporator coil and to a second evaporator coil surrounding a liquid receiver connected by a conduit with the reclaim condenser. A power cylinder axially vertically positioned above a vertically upright refrigerated block drives a piston rod connected to a T-shaped piston screw small diameter shank projecting through a slightly larger diameter bore within the bottom of an upwardly open cup-shaped piston slidable within the refrigerated block receiver chamber. The piston rod has a spherical lower end which seals off the bore thereof expelling condensed liquid refrigerant from the receiver chamber. Vapor flows from the receiver chamber into the mounting tube and condensed liquid refrigerant drains into the receiver chamber during raising of the cup-shaped piston.
