Choose an option
-
AHigher condensing temperature
-
BLower condensing temperature
-
CSame condensing temperature
-
DUnrelated/independent
Answer
Correct Answer: Lower condensing temperature
Explanation
Concept/ApproachWater has higher heat-transfer coefficients and can be supplied cooler than ambient air (via cooling towers or mains), so the condenser saturation temperature (and pressure) can be reduced.
ImplicationLower condensing temperature reduces compressor work and improves system COP.
Final AnswerLower condensing temperature
