内蒙古西部草原民居热环境分析及供暖模式

Thermal Environment Analysis and Heating Mode of Grassland Dwellings in West of Inner Mongolia

为了改善内蒙古西部草原民居冬季室内热环境和热舒适性,对内蒙古西部地区271户草原民居进行调研,分析具有代表性的典型民居在现有土暖气与落地炕供暖模式下的室内热环境状况,在典型草原民居的基础上提出南向附加阳光间、节能型吊炕及风能供热系统,利用Design-Builder软件分析内蒙古西部现有典型草原民居住宅与优化后的住宅模型2种居住模式在额济纳旗、鄂托克旗、阿拉善左旗吉兰泰镇及巴音毛道农场等地的气象参数条件下卧室和客厅的室内热环境状况。结果表明:在现有土暖气与落地炕的供暖模式下,测得该民居冬季最冷月室内平均温度为14.55℃,热舒适度平均值为-2.56;优化后的民居模型室内热环境及舒适度较典型民居均有显著的改善,4个地区最冷月平均室内温度为19.17℃,热舒适度模拟值为0.1。

To improve the indoor thermal environment and thermal comfort of grassland dwellings in the west of Inner Mongolia in winter,271 grassland dwellings in the west of Inner Mongolia were investigated,and the indoor thermal environment of representative typical dwellings under the current heating mode of soil heating and ground Kang was analyzed.Based on the typical grassland dwellings,the south additional sunshine room,energy-saving hanging Kang and wind energy heating system were proposed.The thermal environment of the bedroom and living room in Ejina Banner,Etok Banner,Jilantai Town and Bayin Maodao Farm of Alxa Left Banner were analyzed by using Design-Builder software.The results show that the average indoor temperature in the coldest month in winter is 14.55℃and the average thermal comfort is-2.56 under the existing heating mode of soil heating and floor Kang.The indoor thermal environment and comfort of the optimized model are significantly improved compared with the typical model.The average indoor temperature in the coldest month in the four regions is 19.17℃and the simulation value of thermal comfort is 0.1.
