摘要
从制冷降温原理的角度出发,通过与传统机械制冷空调送风状态点的确定方法进行对比,介绍了蒸发冷却空调的空气处理过程中直接蒸发冷却等焓降温、间接蒸发冷却等湿降温、复合式蒸发冷却先等湿降温后等焓降温的特点。根据以上特点,针对不同的空调系统形式,分析了确定蒸发冷却空调送风状态点的图解法与计算法。最后分别以全空气、空气—水系统为例,详细说明了计算法的计算步骤及公式。
Starting with the refrigerating and cooling principle, the article, through the comparison with the determining method of air-supply status points of traditional mechanical refrigeration air-conditioners, introduces the isenthalpic cooling characteristics in the air treatment process of evaporative cooling air-conditioners, such as direct evaporative cooling isotherm cooling,indirect evaporation cooling and other wet cooling, composite evaporative cooling first wet cooling. Based on the characteristics above, and for different air- condition systems, the article analyzes and determines the graphic method and calculation method of air- supply status points of evaporative cooling air-conditioners. At last, the article makes the detailed description of the procedure and equation of the calculation method.
