Reasonable Energy Consumption Correction Method for Ventilation and Air-conditioning of Platform Screen Door Metro Stations in China
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 6
Abstract
Objective In view of the continuous growth of energy consumption in metro stations, in order to accurately evaluate their current energy consumption level, tap energy conservation potential and promote energy conservation of buildings, it is necessary to revise the reasonable energy consumption of ventilation and air-conditioning in platform screen door metro stations. Method Based on the principle model of energy consumption, the reasonable energy consumption benchmark for metro stations in various climate areas is established systematically. For the typical cities in different climate areas including cold area, hot summer and cold winter area, hot summer and warm winter area, the energy consumption constraint value and guiding value of the ventilation and air-conditioning system in platform screen door metro stations under basic working conditions are obtained by simulation. In consideration of the climate differences and station services in different areas, the influence intensity of climate conditions, passenger volume, the number of train departures and tunnel length on the energy consumption of metro station ventilation and air-conditioning system is quantitatively analyzed.The revised calculation method is proposed for reasonable energy consumption of ventilation and air-conditioning system in metro stations with platform screen doors under different service conditions and in different cities and different climate areas. Result & Conclusion The annual mean wet-bulb temperature in climate conditions is highly correlated with energy consumption，showing a correlation coefficient R2 of 0.950. The reasonable energy consumption indicator of each climate area increases by 2.2% to 2.9% when the annual total passenger volume increases from 5 million to 11 million,showing little difference among climate areas. The indicator increases by 2.0% to 7.4% when the number of daily total departure trains increases from 140 to 310 pairs, showing obvious difference between different climate areas.The indicator of stations with a 1 200 m long tunnel is 1.5% to 4.9% higher than that of stations with a 800 m long tunnel,showing obvious differences between different climate areas.
