Abstract

Global climate change is predicted to cause more unusual events such as heatwaves. Fans can be used instead of compressor-based AC to reduce heat strain on people, while reducing energy consumption, environmental impact, and grid stress. In extremely hot and dry environments, fan use is not beneficial because skin is dry and lost evaporative cooling benefit. This study evaluates evaporative coolers to cool down the air below thresholds at which fans can be used to reduce heat strain. The results show great potential, with temperature reduction up to 7 °C. Moreover, evaporative coolers in place of AC would reduce power consumption by at least 62-74%.
