太阳能风能化石能耦合采暖改善内蒙古西部草原民居冬季室内温度与热舒适性

Solar-wind-fossil energy coupled heating to improve indoor temperature and thermal comfort of houses in western Inner Mongolia grasslands in winter

为改善内蒙古西部草原民居冬季室内温度和热舒适性,选取102户草原民居对居住人员情况、冬季采暖方式、室内热舒适情况、家庭用能情况进行调研,对室内外的空气温度进行实测。构建太阳能风能化石能耦合采暖模型,并利用Design-Builder软件对室内各空间温度和室内热舒适性进行模拟,并与现有的连灶炕+土暖气采暖方式进行比较。研究结果表明:太阳能风能化石能耦合采暖方式在不开启反烧炉的情况下比现有采暖方式在最冷月室内平均温度提高2.26℃,热舒适满意度提高48.76个百分点;在开启反烧煤炉系统并每日平均燃烧3kg煤炭的情况下比传统采暖方式在最冷月室内平均温度提高4.23℃,热舒适满意度提高61.2个百分点,室内温度和热舒适性得到显著改善。为今后该地区草原民居采暖方式的选择和太阳能风能资源的利用提供一定的借鉴。

In order to improve the indoor temperature and thermal comfort of houses in the west of Inner Mongolia, 102 houses in grassland were selected to investigate the living conditions, winter heating methods, indoor thermal comfort, and household energy use. The indoor and outdoor air temperature was measured. The solar-wind-fossil energy coupling heating model was constructed, and the indoor temperature and indoor thermal comfort were simulated by using Design-Builder software, and compared with the existing heating methods of connected stove-kang and old water heating system. The results show that: the solar-wind-fossil energy coupling heating method can increase the average temperature of the indoor average temperature by 2.26℃ in the coldest month compared with the prior heating mode without opening the anti-burning furnace, and the thermal comfort satisfaction degree is improved by 48.76%. The average indoor temperature in the coldest month increases by 4.23℃ and the satisfaction of thermal comfort increases by 61.2% compared with the traditional heating mode under the condition of turning on the backfired coal furnace system and burning 3 kg coal carbon per day on average. The indoor temperature and thermal comfort improved significantly. It provides some reference for the selection of heating mode and the utilization of solar and wind energy resources in this area.
