← TechnologyWhich outcome occurs when heat input exceeds vapor compression chiller capacity?
A)Refrigerant subcooling temperature will decrease
B)Compressor motor overheating is more likely✓
C)Evaporator coil capacity increases significantly
D)Coefficient of performance (COP) improves abruptly
💡 Explanation
Compressor motor overheating becomes likely as the heat overload increases the refrigerant pressure and temperature beyond design limits; therefore, the motor must work harder, rather than improve COP; this exceeds cooling capacity via the vapor-compression cycle creating increased heat load.
