Abstract
A refrigerant recovery system includes a refrigerant circuit with a vacuum pump, a first connection port, a second connection port, an exhaust port, and multiple-way valves that selectively fluidly connect said ports to the vacuum pump. The multiple-way valves have a first configuration, a second configuration, and a third configuration for fluidly connecting the ports to a suction inlet and a discharge outlet of the vacuum pump. A method is for recovering refrigerant from a refrigerant circuit using a refrigerant recovery system. The method includes operating the refrigerant recovery system in a liquid recovery configuration to transfer liquid refrigerant in an refrigerant circuit into one or more recovery cylinders and operating the refrigerant recovery system in a gas recovery configuration to transfer gaseous refrigerant in the refrigerant circuit into the one or more recovery cylinders. A recovery cart includes a transfer circuit of a refrigerant recovery system.
