摘　　要：当前空气源热泵冷热水两联供系统过滤网结构孔径分布不均、结构单一,导致大流量下的总流阻不够大,过滤效果不佳。针对该问题,本文提出了基于改进遗传算法的过滤网结构优化方法。计算滤网流阻、沿程流阻,分析过滤网流量。使用改进遗传算法的直接编码方式,优化孔径分布,平衡污染物拦截与低压降。采用列交叉法优化多层结构,形成稳固支撑框架。由实验结果可知,该方法在100 L/s流量下的总流阻达到最大,为42.0 kPa,与实验指标一致,有效提高了过滤效率。The current air source heat pump cold and hot water dual supply system has uneven pore size distribution and a single structure in the filter mesh structure,resulting in insufficient total flow resistance and poor filtration effect under high flow rates.A filter structure optimization method based on improved genetic algorithmwas proposed to address this issue.Calculate the flow resistance of the filter screen and the flow resistance along the way,and analyze the flow rate of the filter screen.Using an improved genetic algorithmfor direct encoding,optimizing aperture distribution,balancing pollutant interception and lowpressure drop.Adopting the column crossing method tooptimize the multi-layer structure and form a stable support framework.According to the experimental results,the total flow resistance of this method reaches its maximumat a flowrate of 100 L/s,which is 42.0 kPa,consistent with the experimental indicators and effectively improves the filtration efficiency.
