EXPERIMENTAL STUDY ON THERMAL AND HUMID ENVIRONMENT OF SUBWAY STATIONS IN WINTER IN SEVERE COLD AREA
Subway station is the important part of an urban public transportation,which has a significant impact on the quality and experience of citizens'travel.Taking Harbin Metro Line 2 as the case,five representative stations are selected to study the thermal and humid environment and thermal comfort of subway stations in winter in cold re-gions.Field measurement and questionnaire survey are used to analyze and evaluate the thermal environment of pub-lic areas in Harbin subway stations based on HDR index.The research shows that 95%of the public areas of subway stations meet the requirements of temperature and humidity,which meets the basic requirements of subway stations.According to the voting results,more than 80%of passengers in the thermal environment and wet environment of the public area of the subway station accept it,and the HDR value is within the specified comfort range in winter,meet-ing the requirements of thermal comfort.This study may provide the theoretical reference for the ventilation opera-tion of subway stations in winter in cold regions,and is conducive to creating a good thermal and humid environment.
