摘　　要：为了解决内蒙古西部草原民居围护结构构造单一,供暖方式落后,采暖效率低、室内热环境质量差并造成石化能源的大量浪费污染环境这一问题,研究以超低能耗为目标,充分利用当地丰富的太阳能与风能资源,构建风力发电系统、被动式阳光间及保温窗帘系统、太阳能热水循环系统组成的新型供暖系统,在此基础上利用正交试验对影响围护结构的阳光间进深、窗框材质、南向窗墙比、玻璃材质、保温层厚度、保温层材质、墙体材质7个主要因素以能耗为指标进行分析,选出最优组合方案。结果表明:最优组合方案与原始方案相比,能耗每年减少12674.79 Kw·h,能耗降低率为77.99%,季室内平均温度提高了8.77℃,PMV值提高了1.86,满足冬季室内人员采暖与舒适度的要求。For grassland dwellings in western Inner Mongolia,it has single enclosure structure,backward heating method,low heating efficiency,poor indoor thermal environment quality and large waste of petrochemical energy causing environmental pollution.Aiming at ultra-low energy consumption,this paper makes full use of abundant local solar and wind energy resources to construct a new heating system composed of wind power generation system,passive solar room and insulated curtain system and solar hot water circulation system to solve these problems.Based on the new system,the orthogonal experiment is used to study the seven main factors affecting the envelope structure,including the depth of the solar room,the material of the window frame,the ratio of the south-facing window to the wall,the material of the glass,the thickness of the insulation layer,the material of the insulation layer,and the material of the wall.By analyzing the energy consumption indicators,the best combination plan is selected.The results show that:compared with the original scheme,the annual energy consumption of the optimized combination scheme is reduced by 12674.79 kw·h,and the energy consumption reduction rate is 77.99%.The average indoor temperature increased by 8.77℃and PMV increased by 1.86,which meets the requirements of indoor heating and comfort in winter.
