摘　　要：通过对淋水密度及水气比、气水比概念的学习,探讨了三者之间的关系。淋水密度根据直接、间接蒸发冷却不同而不同,一般用淋水密度来评价填料式直接蒸发冷却换热效果,水气比一般用来评价喷水室直接蒸发冷却,而气水比则是在蒸发冷却冷水机组中经常会提到的一个概念。淋水密度和水气比根据喷水量多少对直接蒸发冷却冷却效率的影响大小不同而不同,水气比和气水比根据处理对象不同而不同。This paper through study the concept of water drenching density and water-gas water, gas-water ratio, explores the relationship among the three. According to the direct, indirect evaporative cooling, water drenching density is different, water drenching density is generally used to evaluate the effect of heat transfer for drip padding direct evapo- rative cooling, water-gas ratio is generally used to evaluate the water spraying direct evaporative cooling, and gas-water ratio is often mentioned in the evaporative water chiller unit. According to the different influence of how much water spray quantity to direct evaporative cooling efficiency, water drenching density is different with water-gas ratio, according to the processed object is different, water-gas ratio and gas-water ratio are also different.
