← ScienceWhich outcome occurs when a refrigeration system experiences reduced refrigerant mass flow?
A)Decreased evaporator heat absorption rate
B)Increased superheat temperature at evaporator exit✓
C)Elevated compressor discharge pressure occurs
D)Reduced condenser subcooling delta results
💡 Explanation
Increased superheat at the evaporator outlet happens because decreased refrigerant allows earlier phase transition to vapor, resulting in less liquid refrigerant absorbing heat; therefore, the vapor overheats rather than maintaining saturated conditions.
