寒冷地区农村建筑室内热环境节能改造策略研究

Study on Energy-saving Reconstruction Strategy of Rural Buildings in Cold Regions

本文通过对河北省典型农村建筑的实地调研,掌握了农村建筑围护结构的典型构造和人员行为,搭建多目标优化模型,通过20代种群的遗传寻优,确定了能耗、热舒适和经济性三者最优化的农村建筑改造策略。最优方案所对应的围护结构组合为wall8+roof6+window1,优化后的方案达到了节能50%的目标,热舒适不满意率下降了6.7%。

Based on the field investigation of typical rural buildings in Hebei Province,this paper understands the typical structure and personnel behavior and builds a multi-objective optimization model.Through the genetic optimization of 20 generations of population,the optimal strategy of energy consumption,thermal comfort and economy was determined.The combination of envelope structure corresponding to the optimal strategy is Wall8+Roof6+Window1.The optimized scheme achieves the energy-saving target of 50%and the thermal comfort dissatisfaction rate decreases by 6.7%.
