Abstract: The study of indoor human thermal comfort is a long-term, interdisciplinary and continuous exploration process, and indoor air parameters have a major impact on human thermal comfort. In order to study the impact of indoor air parameters on human thermal comfort, the PMVevaluation indicators were transformed into mathematical graphical analysis through Maple programming. The temperature and wind speed ranges of human thermal comfort were summarized, and the air conditioning supply parameters and indoor space coverage of thermal comfort were analyzed. The air conditioning supply uniformity ratio was calculated, and the air conditioning supply scheme design was carried out. Conduct air conditioning experiments based on the calculated data, analyze the experimental results, and use STAR-CCM software to simulate and verify the indoor air flow field and temperature field. Setting the air conditioning supply mode based on the thermal comfort of the human body can reasonably reduce building energy consumption and provide guidance for air conditioning design.
