Because of its advantage of energy saving, economy, environment protection and the quality of indoor-air improving, the evaporative cooling technology is used more and more in the project. The electricity consumed by this direct evaporative cooling air conditioner is 20% of that of the traditional air-conditioning system. The structure and principle of this new kind of direct evaporative cooling air conditioner are discussed. The performance of the fibrous composite filler used in this air conditioner is fully discussed. With the psychrometric chart, the air handling process is analyzed. The experiment data corresponding to different weather conditions are given at the same time. Many applied projects and its application prospect are introduced. The problem existed is also discussed.
