Abstract
A refrigerant recovery system includes a first oil separator including a chamber configured to receive refrigerant from an air conditioning system, a heat exchanger disposed within the first oil separator, and a compressor fluidly connected to the chamber and the heat exchanger. A first valve is disposed in a first flow line that is fluidly connected between an inlet of the first oil separator and a source of refrigerant and a second valve is disposed in a second flow line that fluidly connects the compressor and the heat exchanger. A controller is configured to open the first valve to enable refrigerant to pass into the chamber of the first oil separator, open the second valve so that a flow loop for refrigerant is formed between the heat exchanger and the compressor, activate the compressor to heat the refrigerant flowing through the flow loop, and subsequently commence a refrigerant recovery operation.
