Refrigeration cycle state point: condition of refrigerant after the compressor and before the condenser Evaluate the statement about a vapor-compression system: “After leaving the compressor and before entering the condenser, the refrigerant is in the superheated-vapor state.” Choose whether this statement is correct.

Difficulty: Easy
Choose an option
-
AAgree — discharge is high-pressure superheated vapor.
-
BDisagree — it is saturated vapor at compressor exit.
-
CDisagree — it is subcooled liquid leaving the compressor.
-
DTrue only for centrifugal compressors, not for reciprocating.
Answer
Correct Answer: Agree — discharge is high-pressure superheated vapor.
Explanation
Cycle reasoningCompressor raises pressure and temperature of the incoming vapor. The exit state is typically a superheated vapor at condenser pressure. The condenser then desuperheats, condenses, and (optionally) subcools the refrigerant.
Final AnswerAgree — the refrigerant is superheated vapor between compressor and condenser.
