Simulation Study On Wind Environment Of University Dormitory In Cold Area Of Hebei Province

With the development of economy and the implementation of higher education,people pay attention to the planning and construction of campus in colleges and universities.As one of the most important buildings in colleges and universities,dormitory building has a direct impact on the quality of life of students.For college dormitories,scientific and reasonable wind environment design is not only conducive to building energy saving and reducing energy consumption,but also provides a comfortable and safe campus environment,so it is necessary to study the wind environment of college dormitories.This thesis uses PHOENICS software to simulate the wind environment,analyzes the indoor and outdoor wind environment of university dormitories,and puts forward optimization strategies.This thesis mainly studies the following aspects:(1)Eight cities in cold regions of Hebei Province were investigated by network,including Handan,Xingtai,Shijiazhuang,Cangzhou,Baoding,Langfang,Tangshan and Qinhuangdao.Twenty-nine universities were selected for statistics,and the analysis was made from two aspects: dormitory building single design and dormitory group layout.68 dormitory buildings are summarized,and the cluster analysis shows that they are linear,L-shaped and U-shaped,and the determinant is the most found in the layout of 37 dormitory groups.(2)According to the investigation results,referring to the relevant codes and documents,starting with the design of single dormitory,firstly,six kinds of straight,Lshaped and U-shaped dormitory standard floors are established,and their indoor wind environment is simulated and analyzed;According to the simulation results of indoor wind environment,taking a straight-line dormitory as an example,this thesis discusses the influence of the changes in the depth,width and direction of the dormitory on the wind environment around the building during the design of the dormitory,and establishes15 different working conditions.Starting with the layout of dormitory groups,30 working condition models are established from five aspects: building spacing,building density,plane organization,group orientation and square position.All the established models are simulated in Phoenics according to the environmental parameters of summer monsoon and winter wind respectively.(3)According to the simulation results,the average wind speed and wind speed ratio are quantitatively analyzed,and the static wind area and strong wind area are qualitatively analyzed.According to the comparative analysis of wind speed cloud map,wind pressure cloud map and building surface wind pressure map,the wind environment optimization strategy of university dormitory in single design and group layout is summarized.This thesis studies the relationship between dormitory layout and natural ventilation from the perspective of dormitory layout mode,which provides a theoretical supplement for the study of dormitory construction in cold areas to some extent.Based on the simulation results,the optimization strategy of university dormitory construction is put forward,which provides an ecological and energy-saving design mode for university dormitory construction and has good reference significance for the practice of green university dormitory in cold areas.
