Analysis of indoor operation temperature based on thermal comfort and thermal health for residential buildings in hot summer and cold winter zone

The concepts of human thermal comfort and thermal health are identified, and the evaluation methods and temperature evaluation parameters based on thermal comfort and thermal health are briefly described. The temperature evaluation parameters include thermal neutral temperature, acceptable temperature and tolerance temperature. In this study, the thermal neutral temperature and the acceptable temperature in the hot summer and cold winter zone are investigated by relevant literature. The thermal neutral temperature ranges from 24.3 ℃ to 28.3 ℃, and the acceptable temperature ranges from 24.2 ℃ to 31.6 ℃ in urban areas in summer. The thermal neutral temperature ranges from 15.4 ℃ to 26.5 ℃, and the acceptable temperature ranges from 10.0 ℃ to 29.7 ℃ in urban areas in winter. The thermal neutral temperature ranges from 25.6 ℃ to 29.8 ℃, and the acceptable temperature ranges from 21.8 ℃ to 31.6 ℃ in rural areas in summer. The thermal neutral temperature ranges from 9.8 ℃ to 15.5 ℃, and the acceptable temperature ranges from 4.95 ℃ to 26.00 ℃ in rural areas in winter. Besides, this study summarizes the range of tolerance temperature, focusing primarily on the healthy and disease-free individuals aged 18 to 65 years old. For this group, the indoor thermal tolerance temperature is 28 ℃ to 32 ℃, and the indoor cold tolerance temperature is 10 ℃ to 14 ℃. However, the cold tolerance temperature of the elderly should be higher, ranging from 14 ℃ to 18 ℃. Through the analysis and the investigation of indoor temperature parameters, it can provide a reference for the temperature design of thermal comfort and thermal health of residential buildings in the hot summer and cold winter zone.
