Abstract

The increase in average annual and summer temperatures in cities adversely affects the health of residents. To address the effects of climate change on urban populations, outdoor microclimate systems that spray liquid droplets are utilized. However, these systems have significant drawbacks, including high water usage and limited efficiency in reducing temperatures. In areas facing water scarcity, such as many Asian countries, microclimate systems that utilise ultrasonic mist generators appear to be a more viable option. This article presents a study examining the operation of a physical model of a climate system incorporating ultrasonic mist generators. Experimental data indicate that the cooling effect is evident within the first 2-3 minutes of system operation, with a temperature decrease rate of 0.7 oC/min observed. A mathematical model has been derived that describes the process of temperature reduction in the unit operation zone. The model is based on a hyperbolic function.
