Which outcome results when a refrigeration system is operated under conditions exceeding its condenser's design pressure?

A)Increased superheat occurs in the evaporator
B)Refrigerant undergoes excessive phase transition
C)Compressor bearings suffer lubrication failure
D)TXV maintains superheat perfectly due efficiency

💡 Explanation

Excessive pressure prevents efficient heat rejection, because saturation temperature of the refrigerant increases. This causes the phase transition from gas to liquid to be incomplete; therefore, refrigerant floods the system rather than subcooling properly.
