摘　　要：为缓解区域供能紧张现状、提升清洁取暖工作成效,基于Rhino-Grasshopper可视化编程平台,以采暖碳排放、采暖季室内热舒适、改造全局成本增量为优化目标,构建河北平原地区“双替代”农宅低碳化改造多目标优化设计模型。结果表明:“双替代”农宅具有较大的性能优化潜力,低碳化改造后Ⅰ类农宅(燃气壁挂炉)的3项目标性能均优于Ⅱ类农宅(空气源热泵);Ⅰ类农宅最优改造方案为120 mm外墙/180 mm屋面防火蜂巢隔离保温板(EPS)+三玻双中空外窗+无吊顶,该方案可减碳91.6%、室内热舒适改善56.8%、全局成本增量-58739元;Ⅱ类农宅最优改造方案为110 mm外墙/160 mm屋面EPS保温板+三玻双中空外窗+室内无吊顶,该方案可减碳90.6%、室内热舒适改善53.6%、全局成本增量-26571元。In order to relieve the tension of regional energy supply and improve the efficiency of clean heating,a multi-objective optimization design model for low-carbon transformation of rural houses was designed based on Rhino-Grasshopper visual programming platform,and where carbon emission,thermal comfort and global cost were taken as the optimization goals.The results show that“double substitution”rural houses has great potential of performance optimization.After low-carbon transformation,three performance of class Ⅰ(gas boiler)rural houses are better than that of classⅡ(air source heat pump)rural houses.The optimal renovation scheme for class Ⅰ is 120 mm exterior wall/180 mm roof EPS insulation layer+three-glass double-hollow window+no ceiling,which can reduce carbon emission by 91.6%,improve thermal uncomfortable hours by 56.8%,and reduce global cost by 58739 yuan.The optimal renovation scheme for classⅡis 110 mm exterior wall/160 mm roof EPS insulation layer+three-glass double-hollow window+no ceiling,which can reduce carbon emission by 90.6%,improve thermal uncomfortable hours by 53.6%,and reduce global cost by 26571 yuan.
