← TechnologyWhich outcome increases when superheat drops too low in in HVAC evaporator coils?
A)Compressor damage from liquid floodback✓
B)Evaporator icing from inefficient heat transfer
C)Increased energy waste from higher pressure
D)System failure from refrigerant overcharge
💡 Explanation
When superheat drops too low, liquid refrigerant can floodback into the compressor because the refrigerant isn't fully vaporized in the coil, causing compression of liquid instead of gas, damaging the system. Therefore, compressor damage from flooding results, rather than icing, energy waste, or overcharge, which originate from distinct failures.
