Aolan (Fujian) Industry Co., Ltd is a high-tech enterprise which collects the research & development, manufacture, as well as marketing on evaporative air cooler (desert cooler or swamp cooler) .Since bringing in the energy-saving coolers without compressors in 1998, we had filled the blank market of evaporative air coolers in China. At present, we have national patents of invention and utility model patents. By conforming with ISO9001:2000, we have developed more than 70 evaporative air coolers with high-quality, energy-saving and environment-friendly. And they have been used in different fields, such as industry, trade, communication, service and breeding.
In the extension of international market, we have obtained the CE and SASO certificates for export and our Aolan evaporative cooler have been exported to more than 30 countries and regions, including countries from Europe, America, Australia, Middle East, South Eastern Asia and Africa, making us globally the largest market share among all Chinese manufacturers in the field.
What is the evaporative cooler?
Air cooler, otherwise known as evaporative cooler or swamp cooler, use the evaporation of water to cool an environment. When the air blows past water, some particles on the surface of the water are carried away. Those particles take some heat with them, cooling the air. That is how sweating works: The water particles on the surface of the skin carry off heat with them as they evaporate, cooling the skin. As a bonus, these air coolers use 75 percent less energy than central air conditioners, the Department of Energy reports.
Types of evaporative cooler
Evaporative cooler have different designs. In some, a fine mist is sprayed into the air and then propelled out with a fan. The water in this mist consists of fine droplets, causing the mist it to evaporate quickly, absorbing heat from the air. In other systems, air is actually blown past or through some material covered with water. It can be blown through a fine mesh, for example, or past wet pads. The evaporation cools the wet material, which in turn cools the air.
Levels of Effectiveness
Traditional air conditioners work well in nearly any weather conditions, but evaporative cooling is more suited to some conditions than others. The air can hold only a certain amount of moisture, based largely on temperature. If it reaches that level, water starts to condense out of the air as fast as it evaporates into it, effectively preventing evaporative cooling.
The relative humidity is a measure of the proportion of the maximum humidity the air can contain. For example, if the relative humidity is at 20 percent, the air contains 20 percent of its maximum humidity. On hot, dry days, the air can hold a lot more humidity than it contains, and evaporative cooling can decrease the temperature by as much as 30 degrees Fahrenheit. As it gets muggier, however, evaporative cooling becomes less effective. This cooling method works best in hot dry climates, and worst in hot humid climates.
Summer is coming, How can I choose portable air cooler or traditional air conditioner
portable air cooler and traditional air conditioner are both perfectly viable tools for keeping the room temperature down. The best choice really depends on the climate where the evaporate cooler will be located and also the budget of the owner.
Humidity
portable air cooler use water to cool the room. A side effect of this is that the humidity of the room is increased by an air cooler.
Traditional air conditioner on the other hand, remove humidity by drying ambient air.
Coolants
Traditional air conditioner use coolants like freon in order to cool the air. Environmentalists claim that coolants are harmful to the environment, so portable air cooler is more environmentally friendly by not using coolants.
Air
portable air cooler bring fresh air into the room and work best in open areas, while traditional air conditioner circulate the air and work better in enclosed areas.
Cost

Traditional air conditioner make up 5% of energy bills.
portable air cooler use water, which has an automatic cooling effect, reducing electricity bills by as much as 75%.
Requirements
portable air cooler need a lot of water in order to function. while traditional air conditioner need a lot of ventilation in order to function
