Brings in outside air and exhausts stale air, smoke, odors, and germs.Evaporative cooling is healthy and comfortable because it:.So the cooling power of evaporative systems increases as the temperature increases.īecause evaporative cooling does not use chlorofluorocarbons (CFCs), it does not contribute to ozone depletion. In fact, in humid regions too humidity almost always decreases proportionally as the temperature increases. Evaporative cooling works in all areas of the country, not just in hot, dry climates.Evaporative cooling actually becomes more effective as the temperature increases-just when DX air conditioning becomes less effective.Increases existing equipment cooling capacities without adding mechanical cooling.Cuts mechanical cooling costs 25% to 65%.Reduces DX/chilled water cooling requirements for fresh air.Reduces Electricity consumption by nearly 60-80% compared to Referigerated Air Conditioning.EconomicalĮvaporative cooling is economical because it: What’s so great about evaporative cooling?Įvaporative cooling is economical, effective, environmentally friendly, and healthy. Modern technology has dramatically increased the efficiency and effectiveness of direct evaporative cooling and made possible other types of evaporative cooling too like Indirect evaporative air cooling, indirect/direct evaporative cooling, indirect/indirect evaporative cooling, and indirect/DX evaporative cooling. These simple examples illustrate direct evaporative cooling. Hanging a wet cloth over an open window cools the air passing through the cloth. In fact, this process has been used for hundreds (if not thousands) of years. The cooling media could be as simple as a wet cloth. It is nature’s way of keeping us cool during hot weather or physical exertion.Įvaporative cooling is the use of this evaporation process to cool the air passing through a wetted cooling media. A “cool breeze” is just air flowing over your body evaporating the sweat. This principle is best illustrated in a personal way by chilling effect that you feel when you come out of a swimming pool and a wind blows across your body! The chilling effect is caused by the evaporation process of the water drying quickly from your body. As the name implies, evaporative cooling works by evaporating water into the air stream.
