In case of vapour compression refrigeration system, elevating the evaporator temperature (keeping the condenser temperature constant) results in_____________?
Correct answer: A. Enhanced COP
- A. Enhanced COP
- B. Decreased COP
- C. No change in the value of COP
- D. Increased or decreased COP; depending upon the type of refrigerant
Explanation
Raising the evaporator temperature increases the refrigeration effect and usually reduces the compressor pressure ratio and work requirement. Therefore, the coefficient of performance increases when condenser temperature is held constant.
