Indoors Thermal Environment Simulation And Analysis Of Natural Ventilation In Office Building

As an ancient ventilation, Natural ventilation attention by scholars gradually by its energy-saving and comfort features. Because of its geographical conditions, Shandong region has abundant wind resources. And how to make the rational use of natural ventilation to save building energy and improve indoor comfort became a hot issue in the present study. In this paper, studied the case of natural ventilation human thermal comfort index and effective hours, and simulated a typical office building room distribution of indoor thermal environment, based on the Shandong region meteorological parameters.First of all, obtained the acceptable level of thermal comfort of natural ventilation by questionnaire, and given thermal comfort standards recommended values of Shandong. Then, the article summarized and analyzed climate characteristics in Jinan, Yanzhou, Weifang, Longkou and Chengshantou region respectively. According to typical meteorological year hourly meteorological parameters in China thermal environment analysis of specific meteorological data sets make an analysis of these five areas’ outdoor wind environment in summer and in transitional season. And then studied the distribution of dry bulb temperature, relative humidity, wind speed corresponding. According to regional thermal comfort standards recommended values obtained available hours of the indoor natural ventilation.Secondly, Calculated the typical room of the model’s cooling load. And deduced the indoor ventilation rate required in natural ventilation conditions. According to the analysis and research of outdoor meteorological parameters of Jinan, Yanzhou, Weifang, Longkou and Chengshantou respectively obtained the effective hours in the case of natural ventilation.Finally, Airpak software was used to make simulation for architectural model for indoor airflow. And then analysis of the temperature field, humidity field, velocity field, PMV, PPD on the indoor thermal environment. Recommendations were made to the layout of the Interior staff office location.
