Which outcome occurs when a heat pump operates with a severely restricted airflow across the evaporator coil?

A)Increased supply air temperature

B)Reduced compressor discharge pressure

C)Formation of ice on the evaporator coil✓

D)Elevated superheat in the refrigerant

💡 Explanation

When evaporator airflow is restricted, the coil temperature drops significantly because less heat is absorbed from the air, leading to moisture in the air freezing on the coil. Therefore, coil icing results, rather than increased temperature, pressure drop or superheat elevation which require alternate imbalances occurring within the system.
