Refrigeration & Air Conditioning USCG Question #164 (Set 3)

What is the pressure and condition of the refrigerant entering the receiver of a refrigeration system?

Official USCG Answer & Rule Citation

Correct Answer: Option D — sub cooled high-pressure liquid

Refrigerant flowing from the condenser into the receiver is condensed and further cooled slightly below its saturation temperature, making it a subcooled high-pressure liquid to prevent premature flashing before the expansion device.
