Exploring the Time Accumulation Effect of Thermal Comfort of Public Space—Identification and Division Method of Sequential Spatial Thermal Unit
Under joint action of microclimate and physical form,each position in outdoor space presents different thermal environment characteristics,and a series of thermal units with difference is further formed;since the time sequence and residence time of thermal unit experienced by user are different,there is remarkable difference in overall thermal comfort experience of space,and the problem of time sequence of thermal comfort in time accumulation effect is brought out.Continuous outdoor thermal environment is divided into the thermal unit with remarkable different,which is the basis for in-depth exploration to the regular pattern of overall thermal comfort affected by time sequence problem.This paper takes the outdoor walking space of a university campus with typical sequence space feature as the research example,and combined with questionnaire about thermal comfort,thermal environment parameter measurement and data analysis,the regression equation is established on that basis,where the mean difference values of radiation temperature and wind speed as two environmental parameters that can be easily measured are taken as the independent variables,and the mean difference value of thermal comfort voting is taken as the dependent variable,therefore,a reliable and easily usable method is provided for the identification and division of thermal unit.
