Dry coolers

The water-cooled condensers, cooling towers and evaporative condensers described all use water, the temperature of which will promote the growth of bacteria Legionella pneumophila. With proper water purification and other precautions that are 100%protected against this evil, users may prefer to avoid any risk of using a strict system of water supply. These heat exchangers are usually called dry coolers. They have a similar structure for air cooled condensers, shown in Fig. 6.2.

Fluid circulates through the tubes of the heat exchanger, while air blowing over the outside. Pipes, as a rule, have an extensive surface. The use of dry cooling towers cannot take advantage of lower temperatures of evaporative cooling of water for cooling, and limited temperature dry bulb and not wet. The upper force is therefore required, and the specified size, the compressor will run less cooling capacity.
