On the hitherto installed chillers/rooftop units/dry coolers and air coolers, a significant improvement in cooling was noticed in the summer mode when the pipe bundle is sprayed with water. Tests have been performed on systems that produce water mist (micron-sized water droplets), which are formed by spraying water under high pressure through the nozzles/nozzle openings. When a drop of micron-sized water comes in contact with warm air, it evaporates very quickly, absorbing a certain amount of heat, which results in cooling the air. This improves the operation of the cooler in critical periods when the ambient air temperature is very high. The aim of the test is to determine the improvement of the cooler operation under operating conditions with the application of the described system in relation to the operating mode without water spraying (dry operating mode).
