Research on air distribution optimization based on improvement of indoor thermal environment of existing public buildings

Taking the air distribution that affects the indoor thermal environment of existing public buildings as the research object, aiming at the indoor thermal environment of existing public buildings in different seasons, this article compares and analyses the characteristics of indoor thermal environment under different air distribution forms with the method of combining actual measurement and simulation. The effects of different air distribution forms and parameters on the temperature field and wind velocity field of the thermal environment are analysed, and the main factors affecting the air distribution of the thermal environment in different seasons are clarified. Based on the analysis of the effects, the key factors for improving the indoor thermal environment are compared from the air distribution design level, and the optimization strategies are proposed.
