A Study On The Design Of Landside Entrance And Exit Space For Small And Medium-sized Airport Terminals In Northwest Region

In the energy consumption of small and medium-sized airport terminals in Northwest China,heating energy consumption takes the main proportion,and reducing heating energy consumption has become an important challenge for terminal energy conservation.As the first threshold of the terminal and the transition area of indoor and outdoor space,cold air penetration in winter is the main factor affecting terminal energy consumption.Implementing effective building energy-saving and emission-reduction strategies is an important measure to address this challenge,and designing the land-side entrance and exit space of the terminal building from the perspective of building design is one of the important ways.At present,there is little research content on the land side entrance and exit space of the terminal.This article uses the design method of the land-side entrance and exit space of the terminal building,combined with the green design vision,this paper uses Anylogic and Cradle CFD simulation to conduct quantitative analysis and determine the optimization scheme.The main research contents and results are as follows:(1)Through the investigation of the entrance and exit of typical airport terminals in Northwest China and other regions,through the analysis of the space size and streamline organization of each terminal,the basic rules of landside entrance and exit of large,medium and small terminals are obtained,and the dimensions range of each type of terminal space,depth,height and common streamline organization mode are determined.(2)Analyze the entrance and exit space of commercial buildings and traffic buildings,discuss the existing design methods of the entrance and exit space.At the same time,conduct an in-depth discussion on the design of the terminal landside entrance and exit space,and determine the design methods of the landside entrance and exit space of small and medium-sized terminals from the five aspects of space size,streamline organization,door setting,spatial location and the Angle of the dominant wind direction.It lays a foundation for the selection of influencing factors in the following simulation study.(3)Based on the analysis of the evaluation indexes of the entrance and exit space in the existing literature,the basic evaluation indexes were determined based on the basic requirements of the landside entrance and exit of the terminal.Secondly,the evaluation indexes of the traffic efficiency were increased by considering the attributes of the traffic building.Finally,the evaluation system for the landside entrance and exit space of small and medium-sized terminals was concluded.(4)This chapter obtains the best and worst working conditions by conducting Anylogic human flow organization simulation and Cradle scstream CFD transient simulation research on various working conditions,and carries out quantitative analysis combined with evaluation indexes.It evaluates each working condition intuitively through radar map,and selects different working conditions according to different evaluation indexes.
