Abstract
In this study, an innovative indirect evaporative cooler is presented and experimentally analysed. A prototype was assembled for the experimental investigation of the system and tested in the laboratory environment under the conditions of constant air flow rate of 350 m3/h, circulating water temperatures of 15°C and 20°C, inlet air temperatures of 25°C and 30°C and lastly inlet air humidity of 9g/kg and 13g/kg, respectively. Based on the data obtained during the experiments, calculations were performed for the cooling capacity, cooling efficiency, energy efficiency and exergy efficiency of the system for each case. The findings showed that the highest wet bulb efficiency, dew point efficiency and EER of evaporative cooler were found to be 0.91, 0.62, and 0.77, respectively.
