Study on adaptive thermal comfort of personnel in residential buildings based on tracking test

Abstract

most of the middle and lower reaches of the Yangtze river in China are hot in summer and cold in winter. In order to study the adaptive thermal comfort of indoor personnel in residential buildings in these areas, a tracking test was conducted on 10 free-running residential buildings in Chongqing from July 2017 to August 2018 through a combination of field test and questionnaire survey. Through the study, in this area, occupants' evaluations of thermal environment were summarized and analyzed, the relationship between activity level, Clothing insulation and air temperature was established, the thermal neutral temperature and acceptable temperature range in summer and winter were obtained, and the characteristics of adaptive thermal comfort of people in free-running residential buildings were revealed, which provided a reference for improving the thermal environment of residential buildings in the area with hot summer and cold winter in the Yangtze river basin.
