Human thermal comfort in office buildings in Tianjin

Taking an office building in Tianjin as an example, conducts a whole year research on the impact of indoor environmental parameters on the human thermal comfort by the method of combining field investigation with theoretical calculation. By means of the adjustability of the building air conditioning system, manually changes the relevant parameters influencing thermal comfort. Analyses the influences of environmental and non-environmental factors on human thermal comfort. The results show that the neutral temperature is 24.8 ℃ in summer, and the range of comfort zone is 20.2 to 29.4 ℃ for the office building in Tianjin. The neutral temperature is 21.3 ℃ in winter, and the range of comfort zone is 15.8 to 27.0 ℃. Compares the results with those in other regions of China.
