当外界的空气经过蒸发过滤时（如图）空气温度由点A降至点B。此变化的产生是由于纸帘表面的水蒸发而令到空气降温。此过程就是空气学中的直接蒸发式制冷原理。图中所示的干球温度由33.4°C降到湿球温度27.8°C是在饱和率达92%的情况下产生。蒸发式制冷是一种传统的制冷方式，利用水在蒸发过程中吸收空气中的热量而使空气降温。新一代制冷技术采用降温过滤原理，使用的蒸发纸帘是由密纤维波纹片经交错叠合的工艺设计制成，使机器工作性能显著提升。
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.
