摘　　要：为解决内蒙古西部草原民居室内供热系统热效率低下而造成的室内热环境质量差、能源浪费量大及经济效益差的问题。文章构建了太阳能、风能集成供热系统,利用Design-Builder分析了土暖气+吊炕与集成供热系统两种不同的供热方式在内蒙古西部草原民居的能源消耗量及热环境状况。通过增量成本支出、年运行费用降低额及盈利能力分析,计算出了集成供热系统的投资回收期。结果表明:集成供热系统每年可减少能耗10994.71 kWh,年采暖能耗降低率为62.69%;在集成供热系统下主卧温度提高了7.05℃、PMV值提高了1.69,客厅温度提高了3.38℃、PMV值提高了1.1,次卧温度提高了5.29℃、PMV值提高了2.27;集成供热系统方案静态投资回收期为16.99年,Pt<Pc,方案可行。The energy consumption,for heating a three-bedroom house in western Inner Mongolia by solid fuel burning in adobe-bed and with solar/wind energies,was modeled and simulated with Design-Builder software.The novel heating system comprises windmill generator,batteries,solar panels,energy-saving construction materials,electrical heaters and control unit.The simulated results show that the newly-developed residential heating makes the difference.For example,the annual energy consumption decreases by 10994.71 kW·h,a reduction by 62.69%;the temperatures in master/second bedrooms and sitting-room increase by 7.05℃,5.29℃ and 3.38℃,respectively.Moreover,the investment recovery period was estimated to be 16.99 years.We suggest that the residential heating with solar-wind energies be of some technological interest in construction and interior-decoration of houses in western Inner Mongolia,because of greater economic and social impact,better living comfort,and less carbon-dioxide release.
