← TechnologyWhich outcome occurs when the evaporator's superheat valve fails open in a refrigeration system?
A)Compressor liquid slugging substantially increases✓
B)System efficiency momentarily improves initially
C)Condenser coil's temperature greatly decreases
D)Evaporator coil frosts excessively quickly
💡 Explanation
Compressor liquid slugging dramatically increases because the open superheat valve allows more liquid refrigerant to pass into the compressor; this constitutes flooded suction. Consequently, internal pressures are elevated, therefore potential damage occurs, rather than efficient flash vaporization and cooling.
