Abstract

See full text

A refrigerant service system according to the disclosure includes an inlet port configured to connect to an air conditioning system, a recovery valve fluidly connected to the inlet port, an accumulator fluidly connected to the recovery solenoid valve and including a pressure transducer configured to generate an electronic signal corresponding to a pressure in the accumulator, and a controller. The controller is configured to determine a target pressure for the accumulator based upon a condition of the refrigerant, obtain a current pressure in the accumulator from the pressure transducer, and to operate the recovery valve based upon the accumulator target pressure to control flow of refrigerant from the air conditioning system to the accumulator based upon the obtained current pressure and the determined target pressure for the accumulator.
