Working Principles
Cooling towers bring a cold and dry air mass in counter-flow to hot water that comes from an industrial or air conditioning process. Part of this water evaporates, cooling the rest. The necessary heat for this is approx. 597 Kcal/litre. The cold water produced is then returned into the process to re-initiate the cycle.
The difference between the required cold-water temperature and the wet bulb temperature (cooling limit distance), is significant to determine the size of the tower. The smaller the cooling distance is, the bigger the interchanging surface is needed. The cooling limit distance must be at least 3-4º C. In open cooling towers there is a close contact water-air, which is bigger thanks to the fill packing, providing a large heat exchange surface, improving performance and evaporation.
