【摘要】：进入二十一世纪以来,城市化进程不断加快,而人口超负荷,交通拥挤、堵塞,建筑空间狭小等给城市的建设和发展增添了巨大压力。于是,向地下空间开辟领地已成为国内外城市发展的趋势。地铁、地下商场、地下超市、地下餐饮等地下建筑不断涌现,而地下建筑随着经济的发展越来越多元化,那么地下空间的热湿环境也逐渐成为人们关注的重点。目前国内外对于热舒适性的研究主要针对地上建筑,而对地下空间的热舒适研究还相对较少。由于地下建筑不受太阳辐射作用,其室内热环境(尤其是辐射温度、湿度)与地上空间差异较大,地上空间热舒适性研究得出的相关结论是否适用于地下空间有待验证。因此,对地下空间热舒适性进行调查研究显得非常必要。本文以西安地区部分有代表性的地下空间为研究对象,在对其热舒适性进行问卷调查和实地测试相结合的基础上,分析了西安地区地下空间的热舒适性,得到了西安市地铁站台和地下商业建筑(地下超市、地下商场和地下餐饮)夏季和冬季的热中性温度、可接受温度范围和室内期望温度。通过对地下空间热舒适的问卷调查和实地测试分析得出:1)西安市所调查测试的地下空间全年热舒适水平均较高。地下商业建筑夏季室内温度感觉到舒适的频率较地铁站台高,地铁站台夏季部分时段温度较低;而冬季则相反。地下商业建筑冬夏室内温度、相对湿度、平均辐射温度较地铁站台均偏高。2)分别得到地铁站台和地下商业建筑冬夏季平均热感觉投票值MTS和室内操作温度top的回归方程:地铁站台夏季:MTS=0.410top-10.70热中性操作温度为26.1℃冬季:MTS=0.358top-7.854热中性操作温度为21.9℃地下商业建筑夏季:MTS=0.468top-12.473热中性操作温度为26.7℃冬季:MTS=0.286top-5.875热中性操作温度为20.5℃3)分别得到地铁站台和地下商业建筑冬夏季节的室内期望温度。地铁站台夏季和冬季的期望温度分别为25.3℃、20.5℃。地下商业建筑夏季和冬季的期望温度分别为26.2℃、19.4℃。
[Abstract]:Since the 21 century, the urbanization process has been speeding up, and the population overload, traffic congestion, narrow building space and so on have added great pressure to the construction and development of the city. Thus, opening up territory to underground space has become the trend of urban development at home and abroad. Underground buildings, such as subway, underground shopping mall, underground supermarket, underground catering and so on, are constantly emerging. With the development of economy, underground buildings are becoming more and more diversified, so the hot and wet environment of underground space has gradually become the focus of attention. At present, the research on thermal comfort at home and abroad is mainly aimed at the above-ground buildings, but the thermal comfort of underground space is relatively less. Because underground buildings are not exposed to solar radiation, the indoor thermal environment (especially radiation temperature, humidity) is quite different from the above ground space. Whether the relevant conclusions of the above ground space thermal comfort research is applicable to the underground space need to be verified. Therefore, it is necessary to investigate the thermal comfort of underground space. This paper takes some representative underground space in Xi'an area as the research object, and analyzes the thermal comfort of the underground space in Xi'an area on the basis of questionnaire survey and field test. The thermal neutral temperature, acceptable temperature range and indoor expected temperature in summer and winter of subway platform and underground commercial building (underground supermarket, underground market and underground dining) in Xi'an are obtained. Through the questionnaire survey and field test analysis of thermal comfort in underground space, it is concluded that: 1) the thermal comfort level of underground space investigated and tested in Xi'an is high all year round. The frequency of indoor temperature in underground commercial building is higher than that of subway platform in summer, and the temperature of subway platform in summer is lower than that in winter. Indoor temperature and relative humidity of underground commercial buildings in winter and summer, The average radiation temperature was higher than that of the subway platform. 2) the regression equations of the average thermal sensing voting value (MTS) and indoor operating temperature (top) of subway platform and underground commercial building in winter and summer were obtained respectively: subway platform summer: MTS=0.410top-10 .70 Thermal neutral operating temperature 26.1 鈩，
