【摘要】：自然通风作为一个古老的通风方式,以其节能和舒适的特点而渐渐受到学者们的关注。山东地区由于其地理条件所致,拥有丰富的风力资源,如何合理利用自然通风来节约建筑能耗并达到改善室内的舒适性成为目前研究的一个热点问题。本文以山东地区气象参数为基础,以办公建筑的室内热环境为研究目标,研究了自然通风情况下人体的热舒适指标和自然通风有效时数,并模拟了办公建筑典型房间内室内热环境的分布规律。首先,文章通过问卷调查的方法,得出人们对自然通风条件下的热舒适性的可接受程度,给出山东地区热舒适性标准的推荐值。然后,文章分别对济南地区、兖州地区、潍坊地区、龙口地区以及成山头地区的气候特点进行了总结和分析。根据中国建筑热环境分析专用气象数据集中的典型气象年的逐时气象参数对这五个地区夏季和过渡季的室外风环境进行分析,研究了室外日干球温度、相对湿度、风速等相应的气象参数的分布规律。并根据各地区热舒适性标准的推荐值得出在舒适情况下室内自然通风可利用小时数。其次,对某建筑模型的典型性房间进行室内冷负荷的计算,并推导出在自然通风条件下确保舒适所需的室内通风量。根据室外气象参数,分别对济南地区、兖州地区、潍坊地区、龙口地区以及成山头地区不同室外气象参数的情况下进行分析和研究,在前文的基础上得出在舒适情况下室内自然通风有效时数。本文利用Airpak软件对某办公建筑的典型房间进行了室内气流组织的模拟,并从温度场、湿度场、速度场、PMV、PPI)对室内的热环境进行分析,给出了房间不同位置室内热环境参数的模拟结果,对室内人员办公位置的布局进行了建议。
[Abstract]:Natural ventilation, as an ancient ventilation mode, has gradually attracted the attention of scholars because of its energy-saving and comfortable characteristics. Due to its geographical conditions, Shandong has abundant wind resources. How to reasonably use natural ventilation to save energy consumption and improve indoor comfort has become a hot issue. Based on the meteorological parameters of Shandong region, this paper takes the indoor thermal environment of office buildings as the research goal. The thermal comfort index of human body and the effective hours of natural ventilation under natural ventilation were studied, and the distribution of indoor thermal environment in typical rooms of office buildings was simulated. First of all, through the method of questionnaire, we get the acceptable degree of thermal comfort under natural ventilation, and give the recommended value of the standard of thermal comfort in Shandong. Weifang area, The climatic characteristics of Longkou region and Chengshantou area are summarized and analyzed. According to the hourly meteorological parameters of typical meteorological year in the special meteorological data set for thermal environment analysis of buildings in China, the summer and transitional seasons in these five regions are analyzed. The outdoor wind environment is analyzed, The distribution law of outdoor dry ball temperature, relative humidity, wind speed and other corresponding meteorological parameters are studied, and the number of hours available for indoor natural ventilation under comfortable conditions is worthy of being recommended according to the standard of thermal comfort in various regions. Secondly, the indoor cooling load of a typical building model room is calculated, and the indoor ventilation amount required to ensure comfort under natural ventilation conditions is deduced. According to the outdoor meteorological parameters, the indoor cooling load is calculated in Jinan area and Yanzhou area, respectively. In Weifang area, Longkou area and Chengshantou area, different outdoor meteorological parameters are analyzed and studied, and the effective hours of indoor natural ventilation under comfortable conditions are obtained on the basis of the previous paper. In this paper, the indoor airflow distribution of a typical room in an office building is simulated by using Airpak software, and the indoor thermal environment is analyzed from the temperature field, humidity field and velocity field. The simulation results of indoor thermal environment parameters in different room locations are given, and the layout of office space for indoor personnel is suggested.
