摘　　要：针对遗传算法求解风机盘管管网管径优化收敛速度较慢的弊病,在对管网进行水力分析的前提,提出采用分步优化的策略对遗传算法进行改进,在收敛速度上有较大提高,以42条管段的风机盘管管网为例,计算时间从120min降到2min,大大提高了计算速度。Based upon the result of hydraulic analysis of network,a step by step approach is pro-posed to eliminate the drawbach of slow convergence speed of Genetic Algorithm in optimizing the pipe diameter of fan coil network,and consequently,the computational time required for a network and consequently,the computational time required for a network with42pipe segments is reduced from120minutes to2minutes.
