← TechnologyWhich outcome occurs when R-134a refrigerant's evaporator in automotive AC freezes below its saturation temperature?
A)Reduced cooling due density change
B)Compressor damage via liquid floodback✓
C)Expansion valve failure from iced deposits
D)Condenser corrosion by refrigerant breakdown
💡 Explanation
When evaporator refrigerant freezes, ice forms because supercooling exceeds heat input, allowing liquid refrigerant to flood back to the compressor causing damage. Therefore compressor damage results, rather than reduced cooling, valve blockage, or condenser corrosion which depend on other failure modes.
