← ScienceWhich consequence results when vapor-compression refrigeration cycle irreversibilities increase?
A)Reduced coefficient of performance.✓
B)Increased system cooling capacity.
C)Decreased compressor power input.
D)Lower condenser operating pressure.
💡 Explanation
Increased irreversibilities raise entropy generation, because the thermodynamic perfection is reduced in the cycle. Therefore, the real coefficient of performance decreases, rather than an increase from an ideal cycle. The irreversibilities degrade performance rather than improve capacity.
