摘 要: 本文建立了包括三种设计模式的风机盘管设计计算模型。模型在通用的热力学定律的基础上，采用了二分迭代算法。各模式根据各自的已知条件，选用了不同的迭代变量和迭代判据，并用不同的方法排除了非合理的输入参数，提供了计算盘管机器露点（外壁温）的迭代法,并据此判定干、湿工况。模型在保证输入参数范围最大化及算法正确稳定的前提下，具有全面、稳定、准确及收敛的特点。 关键词 ：风机盘管，算法，机器露点，湿工况，干工况 Research On The Algorithm Of Fan-Coil Design Model Wang Ting Gu Bo Han Hua School of Mechanical and Power Engineering, Shanghai Jiaotong University, Shanghai 200240 Abstract: This study establishes a calculation model including three fan-coil design patterns. The dichotomy iteration, based on the common laws of thermodynamics, is employed. Each design pattern has different known conditions, and accordingly, needs different variables and criteria chosen for iteration. To ensure the stability and validation of the algorithm in the maximal calculation range, illogical input parameters were excluded precisely. Some iterative methods of computing the apparatus dew-point temperature (outer tube wall temperature) are developed to distinguish dry and wet cooling process. At last, the comprehensiveness, stability, correctness and convergence of the model are proved.. Keyword: fan-coil algorithm apparatus dew-point temperature wet condition dry condition
