← ScienceWhich risk increases when a chiller's coolant undergoes cavitation?
A)Decreased heat transfer efficiency✓
B)Increased system thermal resistance
C)Accelerated rate of condensation
D)Reduced evaporative cooling effect
💡 Explanation
Cavitation forms vapor bubbles that collapse violently. Latent heat requirements are higher than sensible heat rather than thermal transfer, reducing efficiency because energy dissipates upon condensation; therefore, decreased heat transfer results rather than resistance which is caused by fouling.
