MAQOLA ANNOTATSIYASI

The paper considers various methods of evaporative cooling used in air conditioning systems. A comparative analysis of the considered methods, limits of application of each method and analysis of technical and economic indicators of the methods are given. The use of evaporative cooling methods in air conditioning systems is one of the most pressing problems. The principle of evaporative cooling is based on the thermodynamic unbalance of atmospheric air, i.e. the difference between the dry and wet psychrometric thermometer temperatures. An analysis of several methods of water evaporative cooling has shown that by using two-stage evaporative cooling and regenerative indirect evaporative cooling it is possible to provide the source with a sufficiently low temperature airflow. The results of the analysis show that evaporative coolers in a refrigeration system consume much less energy than conventional coolers. A two-stage evaporative chiller can provide summer comfort as an environmentally friendly and energy efficient cooling system for Uzbekistan's hot and dry climate. Where direct and indirect evaporative cooling systems cannot meet comfort requirements, the two-stage evaporative cooler can provide comfort in these areas. At the same time, two-stage evaporative cooling allows the airflow entering the source to be reduced to a lower temperature. If it is not possible to additionally humidify the air stream entering the source, regenerative cooling methods are recommended. These evaporative cooling methods produce an optimum inlet airflow temperature for dry and temperate climates.
