What effect does closing air dampers have on condenser capacity?

Closing air dampers reduces the amount of air flowing over the condenser coils. This reduction in airflow leads to less heat being removed from the refrigerant within the condenser. As the airflow decreases, the heat exchange process becomes less efficient, causing the refrigerant to stay warmer and thereby compromising the condenser's ability to reject heat effectively.

When the capacity of a condenser is reduced, it not only affects the condenser's cooling ability but can also lead to increased pressure within the refrigeration system, further impacting the overall efficiency and performance of the HVAC system. Thus, closing air dampers limits the operational capacity of the condenser.
