← ScienceWhich outcome occurs when the throttling valve in a refrigeration cycle fails?
A)Increased superheat temperature at evaporator exit✓
B)Decreased compressor discharge line temperature
C)System overcools and evaporator frost buildup
D)Reduced condenser subcooling with low pressure
💡 Explanation
Increased superheat temperature occurs in the evaporator, because expansion valve failure raises superheat, starving the cooling loop and increasing return temperature through heat exchange, therefore less cooling throughout the cycle, rather than decreased discharge and frost buildup.
