How does an adiabatic cooling system work?

An adiabatic cooling system (adiabatic dry cooler for liquids, adiabatic condenser for gases) is a system that combines the principle of a dry cooler with adiabatic pre-cooling of outside air. During the cold period of the day and/or year, cold outside air is drawn in by fans and comes into contact with a finned coil in which the process fluid (water or gas) is present: in this way, the air itself absorbs heat. In contrast, during the hot period of the day and/or year, a different operation is set up thanks to the electronic control system: in fact, the outside air is pre-cooled by passing through a water-impregnated adiabatic pack. From this point, operations are the same as for a simple dry cooler. However, the water resource used is very small. Video of operation of an adiabatic cooler or condenser.
