ABSTRACT

In this study, with an aim to develop a proper effectiveness-NTU relationship of an enthalpy exchanger having a diagonal flow configuration, heat and moisture transfer experiments were conducted. Test samples having a range of diagonal angles were tested, and the effectiveness ratios between the diagonal flow and the cross-flow configuration were obtained as a function of the diagonal angle. Developed correlations of the heat, moisture, and enthalpy predicted the data within $\pm$3%. Furthermore, it was shown that the moisture transfer effectiveness was highly dependent on the relative humidity and the air temperature.

对角线焓交换器中的传热传质实验

摘要

在这项研究中，为了建立具有对角流配置的焓交换器的适当的效率-NTU关系，进行了热和水分传递实验。测试具有一系列对角角的测试样品，并获得对角流和错流配置之间的效率比作为对角角的函数。开发的热量、水分和焓相关性预测了其中的数据$\pm$3%。此外，它表明水分转移效率高度依赖于相对湿度和空气温度。
