Research On Indoor Thermal Environment Construction Strategy Of Waiting Room Of Small And Medium-sized Railway Station In Hot Summer And Cold Winter Area

With the improvement of people’s living standards,the requirements for travel quality also increase.In recent years,railway travel has become the main choice for people to travel.The waiting room is one of the spaces where passengers stay for the longest time in the railway passenger station.From the perspective of human comfort,it is necessary to create a comfortable waiting environment.However,the comfortable environment of the waiting room is accompanied by large energy consumption,which makes the building energy consumption of the railway passenger station higher than that of ordinary public buildings.Under the background of reaching the goal of carbon peak,carbon neutralization and double carbon,It is imperative to reduce the building energy consumption of railway passenger stations.Under the joint constraints of the two,the research on the construction strategy of indoor thermal environment suitable for railway passenger station waiting room plays an important role in human thermal comfort,energy saving and consumption reduction.Firstly,the relevant theories of indoor thermal environment are combed and summarized.This paper analyzes the influencing factors of indoor thermal environment and human thermal comfort,selects temperature as the research parameters,and selects the relevant thermal comfort evaluation standards to pave the way for the later research.Secondly,combined with the thermal comfort needs of passengers,and considering the climate characteristics,resource endowment and the characteristics of small and medium-sized railway passenger station waiting rooms in hot summer and cold winter areas,this paper analyzes and puts forward the concept of creating a suitable indoor thermal environment for small and medium-sized railway passenger station waiting rooms in hot summer and cold winter areas,so as to provide guidance for the manufacturing technology strategy.Then,the waiting room of small and medium-sized railway passenger station on Chengdu Chongqing high-speed railway line in hot summer and cold winter is investigated on the spot.Through field measurement and questionnaire survey,the actual situation of the indoor thermal environment of the waiting room and the actual needs of passengers are understood respectively,and the existing problems of the waiting room are found and summarized.Combined with the practical problems,under the guidance of the construction concept,the construction technology suitable for the indoor thermal environment of the waiting room of small and medium-sized railway passenger stations in hot summer and cold winter areas is put forward.Finally,the appropriate technology is simulated and analyzed with the help of software.From the building side,conduct specific simulation analysis on the shading structure facilities,roof performance,door and window exterior wall performance and window wall ratio under different orientations,and determine the construction technology strategy.
