HVAC design for a prefabricated project combined with three-dimensional modeling

This paper presents the design of the air conditioning system, ventilation system and smoke control and exhaust system for a prefabricated building. The author discusses the design process of the air supply system for air conditioning and the assembly production and construction process of the seat air supply column embedded parts for the small and medium-sized lecture halls, and presents the setting scheme of civil air cavity of the floor air supply system of air conditioning and the arrangement of the floor air supply outlet of air conditioning with display cabinet emphatically. Finally, this paper gives the three-dimensional design process of the project, displays the results and analyses the necessity of three-dimensional modeling design in prefabricated projects.
