摘要
通过对现行湿垫设计方法存在问题的分析提出一种新的方法:将风机-湿垫系统的流动空气分为2个流动阶段,以湿垫的动态性能参数和系统的热平衡方程为基础,推导出求解系统通风流量的显函数表达式。这是湿垫面积设计合理而简便的一种计算方法。
Some shortages of present cooling pad design method are out- lined.In order to overcome these problems,air moving procedure in fan-pad system is analysed.According to the performance of the moving air,it is nessesary to seperate the whole moving procedure into two moving stages.Based on the energy balance equation and dynamic performance parameters of cooling pad,a model of air moving is established.By solving this model,the rate of ventilation is obtained,and so is the pad area.
