A technique to speed up the recovery process is

• A. Freeze the cylinder
• B. Cool the recovery cylinder
• C. Increase ambient temperature
• D. Open system valve

Answer: (B)

Speed of recovery hinges on the pressure difference between the appliance being serviced and the recovery cylinder. The cylinder’s temperature sets its vapor pressure: cooling the recovery cylinder lowers its vapor pressure, which expands the pressure differential with the appliance and drives refrigerant vapor into the cylinder more quickly. Warming the cylinder would raise its vapor pressure, reducing the differential and slowing the flow. Opening the system valve isn’t a method to speed recovery, and increasing ambient temperature would raise the cylinder’s pressure rather than speed the transfer. Cooling the recovery cylinder is the technique that accelerates the process.
