摘要
为了研究直接蒸发冷却空调的蒸发效率,将依据热力学湿球温度概念所得的空气饱和状态下的最大理论温降与公式法计算所得最大理论温降进行对比,两者相差约1.4%,证明公式法的可信度,指出产品开发中可使用公式法计算出风口相对湿度非100%时的最大理论温降。
In order to study the evaporative efficiency of direct evaporative cooling air-conditioning,the maximum theoretical temperature drop value obtained by thermodynamic wet-bulb temperature concept is compared with that calculated by formula method under saturated state of air,the difference value is about 1.4%,which proves the reliability of formula method.It’s pointed out that the formula method can be used to calculate the maximum theoretical temperature drop value with the outlet air relative humidity except for 100% in the product development process.
