Which outcome occurs when inadequate fin spacing reduces airflow across the condenser coils in a refrigerator's refrigeration cycle?

A)Decreased refrigerant superheat temperature
B)Increased compressor discharge temperature
C)Minimized thermal expansion valve activity
D)Optimized refrigerant subcooling rates

💡 Explanation

Increased compressor discharge temperature rises because reduced airflow diminishes heat rejection via convection. This causes increased refrigerant pressure via the Pressure-Enthalpy relationship governing heat transfer. Therefore, temperature increases rather than decreases in superheat or subcooling.
