What is the advantage of using a pressure relief valve to protect a receiver instead of a fusible plug?
A) Pressure relief valves are less expensive.
B) The pressure relief valve resets itself.
C) Pressure relief valves can also be used to check the receiver pressure.
D) It is impossible for a pressure relief valve to malfunction.
Question 2
Why is it necessary to have controls for maintaining a minimum high-side pressure on outdoor air-cooled condensers?
A) Compressors will not operate correctly if the compression ratio is too low.
B) The chemical components in the refrigerant will separate if the pressure is allowed to drop below the normal minimum operating pressure.
C) The refrigerant will not condense if it is excessively cooled.
D) Refrigeration metering devices require a minimum pressure drop to operate.
