内蒙古西部农宅围护结构热工性能不佳、冬季采暖效率低下、可再生能源利用率不高,导致农宅采暖能耗高、室内舒适度不佳、碳排放量巨大及经济性较差等问题,阻碍了内蒙古西部农宅的绿色低碳转型。文中以实地调研、文献收集的数据为基础,通过DeST和Trnsys软件联合建立农宅基准模型与可再生能源联合供暖系统。选取10 个影响因素与6 个农宅性能指标,基于正交试验法构建绿色低碳方案样本数据集;以训练好的 GA-LSSVM模型作为PSO-NSGA-Ⅲ模型的适应度函数,进行内蒙古西部绿色低碳农宅多目标优化,得到Pareto最优解集;再运用熵权-TOPSIS法得出最优方案。结果表明:与基准模型相比,最优方案节能率达到100%,最冷日室内PMV值在[-1,1]区间内,全生命周期费效比>1,经济上可行,极大的提高了可再生能源利用率的同时有效的减少了碳排放,为内蒙古西部农宅的绿色低碳发展提供了研究方向,在内蒙古西部农村地区具有一定的推广性。
Research on multi-objective optimization of green and low-carbon rural houses in western Inner Mongolia based on improved LSSVM-NSGA-Ⅲ
In western Inner Mongolia,the suboptimal thermal performance of the envelope structure of rural houses,combined with inefficient winter heating and low renewable energy adoption,result in considerable heating energy expenditure,inadequate indoor comfort,significant carbon emissions,and economic hardships.These issues impede the transition to green and low-carbon practices in rural housing.These issues impede the transition to green and low-carbon practices in rural housing.Based on the data collected from field research and literature,this paper jointly established a benchmark model of rural housing and renewable energy co-heating system by using DeST and Trnsys software.Ten influencing factors and six rural housing performance indicatorswere selected to construct a sample dataset for green and low-carbon solutions based on the orthogonal test method.Using the trained GA-LSSVM model as the fitness function of the PSO-NSGA-Ⅲ.model,the multi-objective optimization of green and low-carbon rural housing in western Inner Mongolia was carried out,and the Pareto optimal solution set was obtained.Then,the entropy weight-TOPSIS method was used to obtain the optimal scheme.The results show that compared with the benchmark model,in optimal scheme,the energy saving rate reaches 100%,the indoor PMV value on the coldest day is in the range of[-1,1],the cost-effectiveness ratio of the whole life cycle is>1,which indicates that the optimal scheme is economically feasible,greatly improves the utilization rate of renewable energy,and effectively reduces carbon emissions.The research provides a research direction for the green and low-carbon development of rural housing in the western Inner Mongolia,and has a certain popularization in the rural areas of the western Inner Mongolia.
