System and method for rapid recovery of fluid refrigerant

A method of refrigerant recovery from a vehicle using a service cart having a high-side port and a low-side port each in fluid communication with an active refrigeration circuit of the vehicle, the method comprising:

• engaging the high-side port such that it is open and the low-side port such that it is closed;
• engaging a compressor of the service cart;
• and
• opening the low-side port in response to a high-side pressure data value falling below a first threshold value,
• wherein
• the high-side pressure data is generated by a high-side transducer in fluid communication with the high-side port, and
• the high-side port and the low-side port are controlled by a controller in data communication with the high-side transducer.

A non-transitory processor-readable medium having instructions stored thereon that, when read by a processor in data communication with a service cart having a high-side port and a low-side port in fluid communication with a refrigerant circuit of a vehicle with an engaged refrigerant circuit, cause the processor to perform the steps of:

• engaging a compressor of the service cart;
• opening the high-side port;
• generating high-side pressure data indicating a fluid pressure exhibited at the first high-side port;
• and
• opening the first low-side port in response to the high-side pressure data value falling below a first threshold value,
• wherein
• the high-side pressure data is generated using a high-side transducer of the service cart, the high-side transducer in fluid communication with the high-side port.
