Which inefficiency arises when excessive superheat causes the TXV (Thermostatic Expansion Valve) in an evaporator to overfeed refrigerant?

💡 Explanation

When excessive superheat leads the TXV to overfeed refrigerant, liquid refrigerant can enter the compressor because boiling is incomplete in the evaporator, causing liquid slugging. Therefore, slugging results, rather than reduced capacity which would stem from underfeeding, increased subcooling, or icing stemming from moisture buildup.
