Abstract

This article deals with evaporative cooling devices used in air conditioning systems. Various ways of lowering the air temperature to the dew point have been identified as a result of improvements to the devices considered. It is also indicated that the circulating water temperature in the system can be lowered to the air temperature on the wet bulb thermometer. As is known, recirculating water is often used as a cooling water in process units to reduce water consumption in industrial plants. Circulating water is heated by recirculation and the heated water is cooled in ventilated cooling towers. This method of cooling water by direct evaporation is based on the thermodynamic disequilibrium of atmospheric air and the difference in psychrometric temperatures between dry and wet thermometers. This method of water cooling, offered in air conditioning systems for dry and hot climates, is very effective. Modern, efficient solutions are needed for a wide range of energy-saving techniques in air conditioning systems. One such solution is to pre-cool the air entering the unit (in heat exchangers) or to use natural cooling sources. The use of an energy-saving chiller with an indirect evaporator as a source of cold water in hot and dry climates is therefore recommended in air conditioning systems.
