Evaporative cooling is the reduction in temperature resulting from the evaporation of a liquid, which removes latent heat from the surface from which evaporation occurs. Evap coolers are capable of delivering a high level of cooling power in a highly effective way. Indeed, a portable evap cooler, in the right environment, has become an alternative to air conditioning, especially in warehouses.
According to the Department of Energy, evap coolers can reduce the ambient temperature in a space by up to 15 degrees. They can be highly effective in warehouse scenarios. As a rule of thumb, evaporative cooling can keep a warehouse facility about 20 degrees cooler than the outside temperature.
This type of cooling system circulates evaporated water through the air, which cools and adds moisture to the space or surrounding area and is a cost-effective climate control method. These coolers use very little energy, which makes them an environmentally-friendly option. Evap coolers use about 75 percent less energy than air conditioning units and require limited amounts of water to keep running.
Evap, or swamp, coolers come in a variety of sizes. The usual formula to calculate the appropriate size for a given space is to take the square feet needed to be cooled times the ceiling height. When this number is divided in two, the quotient is the number of CFM (cubic feet per minute) that you want.
A portable evap cooler could be the perfect solution for keeping a cool warehouse, especially in areas with low humidity. With this system, workers, products and equipment can maintain a degree of efficient, cost-effective protection against the heat.
