Study Of The Environment Characteristics Of The Passenger Flow Area In Energy-saving Railway Stations

With the rapid development of China's high-speed railway,medium-sized railway stations are emerging in China.In this paper,a medium-sized railway station is selected as the research object,and the passenger flow simulation software is used to obtain the required size of the entrance passage,so as to determine the plane structure of this station's public area.Then I optimize the layout of public areas,and simulate and analyze the environmental characteristics and comfort of the passenger flow area.This paper through investigation and reading related specifications,important information such as the station's arrival process,service facility size,service capacity and actual operation was obtained.Use the passenger flow simulation software to establish passenger flow simulation model,and according to the survey data to verify the accuracy of the models.Based on the model of peak hour traffic(5000 people/hour)of the passenger flow simulation analysis,get the peak hour traffic under different service window number configuration of queuing situation,combined with service facilities is calculated in the size of each configuration required channel length,width,and then calculate the channel area.According to the shape structure of the station building,use ventilation simulation software to simulate and calculate the seepage air volume of the existing railway station public area in winter and summer typical conditions.The simulation results are used as the boundary conditions of DeST software to calculate the air conditioning cooling load and air conditioning heat load of the reference layout.In view of the unreasonable layout of public area and plane of existing stations based on the demand of anti-terrorism security inspection,the layout optimization scheme(the optimal layout)is put forward.Use the air distribution simulation software to simulate the reference layout and the optimized layout under the same boundary conditions(divided into three optimal layout schemes A,B and C).The simulation results show that the indoor environment characteristics of the three layout schemes are not different in summer and can meet the design requirements,but in winter,the indoor environment of scheme A meets the design requirements,and the indoor temperature of scheme B and scheme C is lower than the design values,and the comfort of personnel is poor.Under the conditions of summer and winter,the indoor temperature and thermal comfort of the optimized layout A scheme and the benchmark layout can meet the requirements,but the area affected by infiltration air in the optimized layout waiting area is significantly less than the optimized layout,the comfort of the waiting area is better,and the air supply volume and energy consumption of air conditioning are smaller.The paper also discussed the optimal layout of the thermal comfort of ticket passenger security personnel.The results show that the thermal comfort of passengers can be satisfied under different working conditions under the optimal layout.In summer,the heat sensation of the staff in the ticketing and security inspection area is between slightly cold and moderate,which meets the comfort requirements.In winter,the thermal sensation of the staff is poor,which does not meet the comfort requirements.
