西安市冬季办公建筑和商场室内热环境调查研究

于2010年1月对西安市5栋办公楼和3栋商场的冬季采暖系统进行调查,测试了建筑室内温湿度等参数,并对室内人员热舒适情况进行了问卷调查。调研结果表明：被调查建筑内热源形式主要为市政蒸汽和燃气锅炉;冬季办公楼和商场内平均空气温度分别为19.9℃和21.1℃,满足热舒适空调的要求,但是商场内平均温度偏高,不符合建筑节能的要求;而两种类型建筑内平均空气相对湿度都要低于30%,空气较干燥。通过问卷调查统计得到办公楼和商场内人们的热感觉、热舒适以及满意程度百分率分布情况,都有高于83%的人感觉满意和刚好满意,满意程度都较高。进一步地分析得到办公楼和商场内实际热中性温度分别为18.8℃和18.7℃,并获得了对应的能被80%的人所接受的热舒适温度范围。

Study of Thermal Environment in Office and Market Buildings of Xi'an in Winter

Five office buildings and three market buildings were studied in Xi’an in January 2010.Temperature,humidity and other thermal parameters were tested,and questionnaires were collected.Results indicated that city heating steam and gas-fired boilers were the major heat resource forms.The average temperature in office and marketplace were 19.9℃ and 21.1℃ respectively,which both satisfied the demand for thermal comfort air-conditioning system.However,the average temperature of marketplace was a little higher,which could’t meet the energy-saving demand.Relative humidity of air in both type buildings was lower than 30%,which showed that the inner air was too dull.Distribution of thermal sensation,thermal comfort and thermal satisfaction were got based on questionnaires.More than 83% of people in office and marketplace feel satisfied or just-satisfied.Neutral temperatures in office and marketplace were 18.8℃ and 18.7℃ respectively,and corresponding temperature zone of thermal comfort which accepted by more than 80% people were also obtained.
