當外界的空氣經過蒸發過濾時（如圖）空氣溫度由點A降至點B。此變化的產生是由于紙簾表面的水蒸發而令到空氣降溫。此過程就是空氣學中的直接蒸發式制冷原理。圖中所示的干球溫度由33.4°C降到濕球溫度27.8°C是在飽和率達92%的情況下產生。蒸發式制冷是一種傳統的制冷方式，利用水在蒸發過程中吸收空氣中的熱量而使空氣降溫。新一代制冷技術采用降溫過濾原理，使用的蒸發紙簾是由密纖維波紋片經交錯疊合的工藝設計制成，使機器工作性能顯著提升。

After the external air through the evaporation (see chart), the air temperature drops from the point A to point B. This change is due to the evaporation of the water in the surface of cooling pad causes the air temperature cooling. This process is called evaporative cooling principle in aerobiology. As shown in the chart, the dry-bulb temperature 33.4 °C drops to wet-bulb temperature 27.8 °C happened at the saturation factor of 92%. Evaporative cooling is a traditional cooling method by absorbing heat in the air when evaporating to make the air cooling. The new technology of cooling adopts evaporation and filtration principle. The evaporative cooling pad being used is made of the dense fiber corrugated sheet by special technique which improves the working performance sharply.
