What effect does stopping the pump have on the condenser sump water temperature?

• A. The temperature remains unaffected
• B. The temperature increases significantly
• C. The temperature decreases rapidly
• D. The temperature fluctuates randomly

Answer: (B)

Stopping the pump has a significant effect on the condenser sump water temperature because it interrupts the flow of water over the condenser coils. When the pump is running, it circulates water that helps absorb heat from the condenser, thereby maintaining a lower temperature in the sump. However, when the pump stops, the water flow is halted, which means that heat cannot be effectively removed from the condenser. As the heat load continues to be applied to the condenser from the refrigerant, the water in the sump begins to absorb this heat without the benefit of circulation. Consequently, the temperature of the sump water increases significantly as the stagnant water absorbs heat from the condenser coils. This phenomenon occurs due to a lack of heat transfer efficiency when the water is not continually moving, ultimately leading to a rise in temperature. In summary, the stoppage of the pump leads directly to a buildup of heat in the sump water, resulting in significantly higher temperatures.
