← ScienceWhich outcome occurs when a refrigeration system's evaporator loses contact with the cooled medium?
A)Compressor overheating due to superheated vapor✓
B)Expansion valve failure from pressure drop
C)Refrigerant phase remains consistently liquid
D)System achieving significantly improved energy efficiency
💡 Explanation
Compressor overheating happens because lack of heat absorption causes superheated vapor, activating the enthalpy of vaporization, rather than the evaporator cooling; therefore, the vapor temperature increases, rather than a change efficiency, due to continuous compression cycle.
