Abstract
The article is devoted to the analysis of energy, economic and environmental efficiency, which are achieved by using indirect adiabatic cooling of air in the central air conditioner instead of direct cooling. Two corresponding schematic diagrams of air conditioning systems are considered. As a result of the calculations, it was found that indirect adiabatic cooling of the air makes it possible to reduce the consumption of cold and electricity by 65%. The monetary equivalent of reducing energy consumption can reach UAH 14,760 for 4 months of operation of the air conditioning system in cooling mode. Also, the use of this mode of operation of climatic equipment makes it possible to obtain a certain environmental effect in the form of reducing carbon dioxide emissions at the level of 5.15 tons per season.Keywords: indirect evaporative cooling, refrigeration capacity, irrigation chamber, economic efficiency, ecological effect
