Analysis of Thermal Comfort under Different Exercise Modes in Winter in Universities in Severe Cold Regions

Abstract

In this study, we collected 927 cases of samples from students at the Harbin Institute of Technology, China and conducted a thermal comfort questionnaire survey on four outdoor exercise modes in winter. Additionally, we analyzed the thermal perception conditions of the campus population in winter, the association between exercise volume and TCV (Thermal Comfort Vote) and the correlation between PET (physiological equivalent temperature) and MTSV (Mean Thermal Sensation Vote). Furthermore, we identified different PET neutral temperatures under different exercise modes (skating 3 °C, running 6 °C, hiking 9 °C, standing 14 °C), the variability of different thermal comforts in the original residence and the trend of thermal comfort with outdoor activity time. Finally, we obtained the prediction model of thermal perception under different exercise modes, and it can used as a basis for assessing the cold outdoor thermal environment to provide some references for environmental designers.
