摘要
分析了横流板式间接蒸发热回收器的热质传递过程,并建立横流板式间接蒸发热回收器的换热数学模型,采用有限容积法对数学模型进行求解,得出了新风、排风沿空气流动方向的温度分布。采用ε-NTU方法对横流板式间接蒸发热回收器的换热效率进行了分析。
The mathematic model of the crossflow plate heat exchanger for indirect evaporative heat exchanger was established, and was solved according to the finite vohune method. Through the numerical solution of the mathematic model, the temperature distribution of the primary air and the secondary air in the flow direction were obtained. The efficiency of ereasflow plate heat exchanger for indirect evaporative cooling was analyzed by the ε - NTU （the number of heat transfer units） method.
