Study On Indoor Wind Environment Of Residential Buildings Based On Space Comfort

The main body and core of the building is space.All of these elements including the enclosure and definition of space,the indoor and outdoor physical environment,the people and the things in the space constitute the actual spatial appearance.In space,in addition to the visual part,most of the underlying objective left is the air.We are surrounded by air currents,sleep,diet,work,study,exercise,recreation and so on,and the wind environment that formed by airflow affects the comfort and physical health of people directly in space,which exist and interact with people all the year round.More and more people have found that the sensitivity of the body to the indoor and outdoor airflow becomes obvious as the age increases.This phenomenon in women,weak and symptomatic people is more prominent,and the body is susceptible to wind,could causing or aggravating adverse reactions in different parts of the body,such as joint pain,cold and other symptoms.The phenomenon is also evident in children.Residential building is the largest building type in China.With the rapid development of our country's society and economy,the living environment of our country has been greatly improved.The demands for living standards have becoming higher and higher,which is no longer limited to simple living function.They have more demands on the quality of life,space environment and the guarantee and promotion of health.Based on the above considerations,this paper discusses the relationship between indoor air flow and human beings under different natural ventilation conditions in residential space,and focuses on the influence of airflow on space comfort.This paper mainly uses research and software simulation methods.Based on the practice of spatial investigation and analysis of common residential buildings,using Airpak(CFD)to simulate the spatial airflow path as the key technology means,and compared with the research results and analysis.In the study,in order to find the essence and simplify the model,the single space was used as the basic simulation object,and the ventilation was organized by doors and Windows.Under the different natural ventilation path,contrast the airflow velocity vector of the main functional spaces,the indoor age of air,the change of temperature,Predicted Mean Vote(PMV),Predicted Percentage of Dissatisfied(PPD)and other indicators.Through thecomparing and analyzing of indoor wind environment,the relationship between indoor people and airflow,indoor comfort level under the natural ventilation path,discuss what kind of ventilation path can effectively guarantee the comfort and the stability of the body,can assure indoor large scale complete effective space with good comfort while replacing the air effectively.Find out the science ventilation layout with doors and windows to design the space scientifically,and provide a healthy indoor air environment coordinating with the people in.So as to provide guidance and recommendations on space design.
