In evaporative cooling, it uses water absorbs a relatively large amount of heat in order to evaporate. An evaporative air cooler reduces temperature significantly, but can’t maintain a particular temperature like an air conditioner. Swamp coolers use the evaporation of water to cool the outdoor air. The cooling process has the potential to lower the temperature of outdoor air by up to 30 degrees in low humidity, but in high humidity evaporative air cooling does not work. 1 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
