Unlike conventional systems that rely solely on electricity and refrigerants, this system works by passing air and water through a heat exchange mechanism in which the water absorbs heat and evaporates, taking the heat along with it. https://alaquainc1.wordpress.com/2025/04/29/what-is-evaporative-heat-exchanger/
