What Is an Indirect Evaporative Air Cooler and How Does It Work?
Introduction If you have ever walked into a building that felt remarkably cool without that sticky, humid feeling typical of air conditioning, you may have experienced an indirect evaporative air cooler in action. This technology is rapidly becoming one of the most preferred cooling methods for commercial buildings, industrial facilities, and data centres around the world. But what exactly is an indirect evaporative cooler, how does it work, and why should you consider it for your next project? What Is an Indirect Evaporative Air Cooler? An indirect evaporative air cooler is a cooling system that reduces the temperature of incoming air using a water-based heat exchange process — without ever introducing moisture into the supply air stream. This is the critical distinction that separates it from direct evaporative cooling, where water is added directly into the air, raising humidity levels. In an indirect evaporative cooler , the primary air (the air delivered into your space...
