ABSTRACT:
A refrigerant recovery and recycling apparatus which transfers refrigerant from a first container to a second container. The refrigerant recovery and recycling apparatus comprises a compressor having a suction side and a discharge side. The suction side of the compressor is in fluid communication with the first container, and the discharge side is in fluid communication with the second container. A liquid/vapor sensor is connected to the first container to detect whether the refrigerant from the first container is in a liquid state or a vapor state. A heater is located between the first container and the suction side of the compressor. The heater is responsive to the liquid/vapor sensor to vaporize liquid refrigerant from the first container. A condenser having an inlet and an outlet is provided. The inlet of the condenser is in fluid communication with the discharge side of the compressor. A filter having an inlet and an outlet is also provided. The inlet of the filter is in fluid communication with the outlet of the condenser, and the outlet of the filter is in fluid communication with the second container.
