← ScienceWhich consequence results when a refrigerant leak occurs in a heat pump operating below freezing?
A)Icing on the evaporator coils✓
B)Increased compressor superheating
C)Decreased condenser subcooling
D)Reduced system vibration damping
💡 Explanation
Icing increases, because water phase transitions at colder temperatures now draw heat from the reduced refrigerant flow, amplifying ice formation in heat exchangers, rather than water passively removing condenser heat. Therefore ice buildup happens, instead of heat transfer enhancement.
