Application of underfloor air distribution system to exhibition hall buildings

This paper presents the concept and characteristics of the underfloor air distribution system. Combined with the application of the underfloor air distribution system to an exhibition building, the problems that should be paid attention to in the design are given, including the calculation method of air conditioning load, the height of thermal stratification, the temperature of supply air, etc. The practical engineering application shows that the underfloor air distribution system can improve the thermal comfort and indoor air quality of the building, effectively release the ceiling space to meet the decoration effect, reduce the energy consumption of the air conditioning system and reduce the life cycle cost of the building.
