A Study Of Summer Thermal Comfort In The Arcade Business Street

Street is not only an important part of the urban space, but also one of the favorite areas for people to shop and relax, showing strong vitality in the city. The hot and wet climate and the development of water transportation make the arcade street came into being. There are various types of space in the arcade street, such as outdoor space, "grey space" and indoor air conditioning space. The main factors which affect thermal comfort in each space are different, therefore the studies must be carried out according to different forms of space.This paper gave a detailed analysis of Nanning's climate condition, summing up Nanning's monthly meteorological parameters, such as air temperature, humidity, solar radiation, wind speed and direction changes in order to facilitate the study of the thermal environment in the future. It summed up the architectural features of the various types of space through analysis of the arcade street.This thesis respectively carried out test and research on the outdoor space, "gray space" and indoor space, and the results showed that the direction and height to width ratio of the street had an important effect on thermal environment; Arcade can create a good shade; temperature and humidity in the street has good correlation with meteorological data instead of the wind speed is not.For street space, the main factor influencing thermal comfort is solar radiation. This thesis uses T-Sun software to study the relationship of among orientation, aspect ratio and hours of sunshine of streets, then figures out the fitting equation. Based on regression equations through the aspect ratio and "internal corner" to provide design strategies for outdoor thermal comfort of street space to create, it classifies the street into east-west, north-south and northeast-southwest directions.In the "gray space", through RWI index calculation results, adequate air movement can bring good comfort. Due to the variability of the wind environment, it uses software PHOENICS to simulate the wind environment from both the architectural scale and component scale, then extract the corresponding laws. The results show that intermittent, back angle, suitable corridor widths, large pillars, floor height are conducive to create a favorable wind conditions.As for indoor space, due to environmental and functional limitations, shops are using air conditioning. Different kinds of airflow PMV and age of air caused a great deal of difference in the shop. Through questionnaires and simulation from the subjective and objective, the author got an understanding of indoor air conditioning thermal comfort of the room. Considering PMV and Age of air, the up sent up return airflow organization form is able to obtain uniform air distribution and comfortable thermal environment.The article studies the outdoor space, arcade "grey space" and indoor space by doing experiment and simulation on sunlight, wind and air flow. A series of optimization strategies thermal comfort in outdoor spaces, "grey space" and indoor space make it possible to design the street in a thermal comfort direction.
