Which outcome occurs when a refrigeration system using HFC-134a leaks past the expansion valve?

💡 Explanation

Superheat increases because the expansion valve allows liquid refrigerant to boil-off prematurely, therefore the refrigerant absorbs more heat from the evaporator to fully vaporise, rather than contribute to cooling the load.
