wet cooling system is in the process of cooling the core base-3 and paper pad to complete. The corrugated surface of the fiber paper with a thin layer of water film, when the outdoor air was dry and hot through the suction fan pad of paper, the water film on the water will be absorbed in the air then evaporated in the heat steam, after proper treatment, the cool moist air entered the room. This natural process is like the wind over the same surface. Cool wet screens films through the water cycle to achieve cooling effect. To save energy, the use of low-cost, long-life, quality assurance, installation, maintenance and use of effective, non-noise characteristics. Cool wet curtain unit is primarily applicable to the agricultural greenhouse sealing
