Air Cooled Condenser – Working Principle, Types, Advantages and Applications
An Air Cooled Condenser (ACC) is a heat exchanger used to convert hot exhaust steam or refrigerant vapour into liquid by removing heat using ambient air. Unlike water-cooled condensers, an air cooled condenser does not require cooling water for its operation. It uses atmospheric air as the cooling medium, making it an environmentally friendly and water-saving solution for industrial and power generation applications.
Working Principle of Air Cooled Condenser
The working principle of an air cooled condenser is based on heat transfer. Hot vapour enters the condenser tubes, while ambient air flows over the outer surface of the tubes. Heat from the hot vapour is transferred to the surrounding air through the tube walls.
As the vapour loses heat, it changes its state from vapour to liquid through condensation. The condensed liquid is then collected and transferred for further use in the system.
Fans are generally used to circulate atmospheric air over the condenser tubes to improve heat transfer efficiency.

Types of Air Cooled Condensers
The major types of air cooled condensers include:
Natural Draft Air Cooled Condenser: Uses natural air circulation without mechanical fans.
Forced Draft Air Cooled Condenser: Uses fans installed below the tube bundles to force air across the condenser tubes.
Induced Draft Air Cooled Condenser: Uses fans installed above the tube bundles to draw air through the tubes.
Advantages of Air Cooled Condenser
