← ScienceWhich outcome occurs in a refrigeration cycle when airflow across the condenser coils is obstructed?
A)Increased compressor discharge line pressure✓
B)Reduced evaporator coil superheat value
C)Lowered subcooling within the condenser
D)Decreased expansion valve refrigerant flow
💡 Explanation
Compressor discharge line pressure increases as refrigerant cannot dissipate heat due to reduced airflow; because the system must work harder to reject heat via the condenser using the compression cycle, the refrigerant temperature and pressure rises, therefore increasing pressure, rather than affecting other parts of the refrigeration system.
