← ScienceWhich risk increases significantly in a refrigeration cycle operating with a superheated refrigerant?
A)Compressor oil breakdown accelerates rapidly✓
B)Condenser heat transfer is more efficient
C)Evaporator coil icing gets diminished
D)Expansion valve flow rate increases
💡 Explanation
Higher discharge temperatures with superheating cause increased Activation Energy. This dramatically increases the rate for Arrhenius degradation reactions in compressor oil because the temperature directly impacts the reaction rate. Therefore, oil breakdown accelerates rather than the other listed outcomes under normal conditions.
