With the development of science and technology and the progress of society,the construction of subway stations in China has entered an era of rapid development.As a kind of public transportation building,the subway station closely affects people's work and life;as a typical transitional space,the heat of the subway station is very important.The environment is different from the thermal environment of a typical building and the requirements for comfort in the thermal environment of a subway station are unique.Satisfaction is a new evaluation index that has been proposed in recent years in various fields,and when applied to the hot and humid environment of a subway station,it not only includes the human body's perception of the hot and humid environment,but also includes the human body's perception of the thermal environment.Environmental satisfaction or not the state of consciousness,but also includes the subjective feelings of personnel on the objective environment,that is,the subway station thermal environment satisfaction by personnel physiological and psychological co-influence.In this paper,we take a certain subway station in Beijing as an object of study to investigate the thermal adaptation of dynamic environment based on satisfaction.The subway station was tested to obtain actual data of objective environmental parameters,and at the same time,the subjective perceptions of passengers were investigated in order to find out the effect of the dynamic environment on the thermal adaptation.A total of 299 valid research data were obtained to discover and determine the best way to assess the satisfaction of the participants based on their hot and humid sensations and parameters.Important factors influencing personnel satisfaction in the hot and humid environment of a metro station.Through the independent comparison and combination analysis of the relevant parameters in the test survey,the distribution pattern is understood in general,and the thermal environment parameters are identified.The significant influencing factor in this parameter is the temperature,and the significant influencing factor in other relevant parameters is the number of people in the metro.Based on the passenger characteristics of the station,the influence of the number of people in the metro can be reduced by time-ofday control,while for the environmental parameters of the metro station-the temperature,however,should be combined with test research and relevant theoretical calculations in order to arrive at a scientific,reasonable and humane temperature that meets the thermal comfort of personnel.Indicators.This paper is based on the study of thermal comfort indicators of the metro environment based on personnel adaptation,including personnel heat and humidity sensation,personnel satisfaction evaluation,dynamic thermal The comfort evaluation indicator HDR.by studying the proportion of data in the optimal evaluation of each indicator,respectively,to derive a neutral based on the perception of personnel heat and humidity temperature zone,a satisfactory temperature zone based on personnel satisfaction,and a comfortable temperature zone based on dynamic thermal comfort evaluation indicators.Finally,the temperature zones for each time zone of the subway station were calculated by combining the subjective test survey and objective theory.In this paper,through the design and effective implementation of a reasonable test survey scheme,the relevant data obtained from the test survey are divided into time zones and other series of time zones.The analysis yielded temperature and humidity intervals based on subjective and objective evaluations,and the method has been relevant to the study of personnel satisfaction in hot and humid environments in subway stations.Certain support.
