近似方程在换热器设计中的应用
Application of Approximate Equation in Heat Exchanger Design
【摘要】 在换热器的设计及换热系统网络优化中, 对数平均温度差( LMTD) 的计算有十分重要的意义- 本文对已提出的近似方程代替对数平均温度差的计算方法进行了评价, 指出J. J. J. Chen 提出的近似方程在换热系统网络设计中优于其他方程
【Abstract】 The Calculation of logarithmic mean temperature difference has a important significance for the design of heat exchanger and the synthesis of optimum heat exchanger network configuration. These proposed approximate calculate equations are discussed, J.J.J.Chen’s approximate equation is better than some others equation that pointed out in this paper.
