What is a potential consequence if the coils in a refrigeration system are significantly sealed?

When the coils in a refrigeration system are significantly sealed or fouled, one of the notable consequences is an increase in the temperature of the condenser sump water. This occurs because sealed or fouled coils reduce the efficiency of heat exchange within the system.

As the coils become less effective in dissipating heat, the heat that would normally be removed from the refrigerant during the condensation process is not transferred adequately. This lack of efficient heat exchange leads to an accumulation of heat in the system, which subsequently raises the temperature of the condenser sump water. The condenser relies on properly functioning coils to maintain effective cooling; hence, when they are sealed, the overall performance deteriorates, resulting in warmer sump temperatures and potentially affecting the entire refrigeration cycle.

This situation emphasizes the importance of regular maintenance and cleaning of coils to ensure optimal operational efficiency and prevent elevated temperatures that can compromise system performance.
