AIR COOLED CONDENSER: Air cooled condenser is used for efficient heat rejection process. Air cooled condenser is also called as coil condenser, its use copper or aluminium coil for heat rejection process. This type using fans to spray the atmospheric air inside the condenser to cooled water or steam and transfer into a liquid state, while compare to water cooled condenser it occupies large area, good quality. Air cooled condenser is of two type of process natural convection and forced convection. * Natural convection of air cooled condenser the air flows depending upon the temperature of the condenser coil. * In forced convection of air cooled condenser the fan operated by a motor blows air over the condenser coil.
