← ScienceWhich outcome occurs when irreversibilities increase within a refrigeration cycle?
A)Reduced coefficient of performance (COP)✓
B)Higher cooling capacity achieved
C)Decreased entropy generation overall
D)Isentropic compression process efficiency
💡 Explanation
Increased irreversibilities lead to reduced COP because they increase entropy generation through processes like friction and heat leak, hindering optimal heat extraction. Therefore, the system performs worse, consuming extra work rather than offering efficient refrigeration.
