Different Evaporative Cooler Uses Explained

With the weather getting hotter, and staying that way for longer, people’s minds are turning to air conditioning to keep cool. While many will automatically reach for exhaust tube air conditioners as the type of air conditioning they know and love there are other options out there. One of them comes in the form of […]

Cooler pads

Traditionally, evaporative cooler pads consist of excelsior (wood wool) (aspen wood fiber) inside a containment net, but more modern materials, such as some plastics and melamin paper, are entering use as cooler-pad media. Wood absorbs some of the water, which allows the wood fibers to cool passing air to a lower temperature than some synthetic […]

Typically, residential and industrial evaporative coolers use direct evaporation and can be described as an enclosed metal or plastic box with vented sides containing a centrifugal fan or ‘blower’, electric motor with pulleys (known as ‘sheaves’ in HVAC]), and a water pump to wet the evaporative cooling pads. The units can be mounted on the […]

Evaporative cooler design

Direct Evaporative Cooling (open circuit) is used to lower the temperature of air by using latent heat of evaporation, changing water to vapor. In this process, the energy in the air does not change. Warm dry air is changed to cool moist air. Heat in the air is used to evaporate water. Indirect Evaporative Cooling (closed circuit) […]

Evaporative cooling

Evaporative cooling is a physical phenomenon in which evaporation of a liquid, typically into surrounding air, cools an object or a liquid in contact with it. Latent heat describes the amount of heat that is needed to evaporate the liquid; this heat comes from the liquid itself and the surrounding gas and surfaces. When considering […]
