aIn most simple systems this is the "log mean temperature difference" (LMTD). Sometimes direct knowledge of the LMTD is not available and the NTU method is used. 在多数简单系统这是“日志平均温差” (LMTD)。 有时LMTD的直接知识不是可利用的,并且使用NTU方法。[translate]...
The main advantage of the NTU method over the LMTD method is that for performance calculations, i.e., determining heat transfer rate and outlet temperatures, the LMTD requires an iterative solution, while with the NTU, the solution can be obtained directly from the formulas. Can the effectivenes...
