Abstract
An equation capable to accurately calculate the wet bulb temperature from the ambient temperature and relative humidity is presented in this paper. Equations for calculation of the outlet air temperature and relative humidity in the direct evaporative cooler are also presented. Direct evaporative cooling is restricted by atmospheric conditions. The outlet air conditions are theoretically determined at different ambient temperatures and relative humidities. Equations for the determination of the outlet air temperature and relative humidity are derived from Psychrometric relations. The equations cover a relative humidity range between 0–100 % and a temperature range between 10–60 oC. The influence of the cooling efficiency of the direct evaporative cooler is considered. The equations yield results that agree closely with values given by existing Psychrometric charts.
