内蒙古西部草原民居太阳能和风能与火炕智能联合供暖模式

Study on intelligent heating mode combining solarenergy,wind energy and heatable brick bed ingrassland residential buildings inwestern Inner Mongolia

摘要:

在实地调研和文献查阅的基础上,提出在内蒙古西部草原民居实行太阳能,风能以及火炕联合供暖的模式。选取86户农牧民对室内温度进行实测。另将现有参数代入到Design Builder软件中进行模拟,将模拟数据与实测数据进行对比,结果表明:智能联合供暖模式相较于传统模式在室内温度和PMV值上都有大幅度提升,以主卧、次卧以及客厅为例,智能联合供暖比传统供暖在温度上分别提高了6.83,6.68和11.15℃。主次卧的PMV值由很冷转变为稍暖、客厅的PMV值由稍冷转变到暖的状态。而智能联合供暖比传统供暖在能耗上节约1 349.35 kwh,可节约标准煤为165.97 kg,节约普通煤为232.45 kg,可减少CO₂排放406.63 kg,CO排放259.41 kg,SO₂排放2.74 kg,室内温度和热舒适度的改善以及能耗减少,为该地区今后研究太阳能、风能利用、供暖方式以及优化能源结构提供一定的参考。

Abstract:

Based on the field research and literature review,a heating system combining solar energy,wind energy and heatable brick bed was designed.Totally 86 farmers and herders were selected to measure the indoor temperature.In addition,the parameters were used for simulation with Design Builder software.The simulated data were compared with the measured data.The results showed that the intelligent combined heating system significant increased the temperature and PMV value compared with the traditional mode.The temperature in master and second bedrooms and living room increased by 6.83℃,6.68℃ and 11.15℃ respectively compared with conventional heatingsystem.The PMV value of primary and secondary bedrooms changed from very cold to slightly warmer,and the PMV value of living room changed from slightly cold to warm.Compared with traditional heating,new system saved 1349.35 kwh of energy consumption,(165.97 kg of standard coal or 232.45 kg of ordinary coal) reduced 406.63 kg of CO₂,259.41 kg of CO and 2.74 kg of SO₂ emission.
