Natural convection air-cooled condensers

In natural convection air-cooled condenser, the heat transfer from the condenser coils to the air is by natural convection. As the air comes in contact with the warm condenser tubes, it absorbs heat from the refrigerant, and thus the temperature of the air increases. The warm air, being lighter, rises up and the cold air from below rises
to take away the heat from the condenser.

Forced convection air-cooled condensers

In forced convection air-cooled condensers, the fan (either propeller or centrifugal) is used to force the air over the condenser coils to increase its heat transfer capacity. The forced convection condensers may be divided into the following two groups:
(a) Base mounted air-cooled condensers, and
(b) Remote air-cooled condensers.
