    In order to study the “partial space” operation mode of the variable air volume air-conditioning system for large space public buildings, numerical simulation and experimental validation methods are adopted to analyze the distribution characteristics of temperature and velocity fields under three operation modes of full-space mode, conference zone-only mode and work zone-only mode. Control strategies and key parameters are identified. The results show that in the two “partial space” operation modes, the temperature in the area where the personnel are located can be maintained near the set value, the air diffusion performance index is higher, and the annual power consumption of the air-conditioning unit is reduced by 35.4% and 52.1%, respectively.
