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.
