← ScienceWhich outcome impairs a refrigeration cycle operating beyond coolant pressure ratings?
A)Compressor experiences cavitation damage ✓
B)Ejector efficiency degrades sharply
C)Evaporator superheat increases rapidly
D)Thermal expansion valve closes fully
💡 Explanation
Cavitation occurs because liquid flashing causes vapor bubbles that collapse violently when pressure increases inside the pump; mechanical damage occurs rather than efficient pumping, therefore rejecting other thermal effects.
