Air outlet automatic selection and layout software development based on Revit platform

This paper designs a set of automatic selection and automatic layout scheme of air outlets based on the calculation results of space load, and develops an air outlet automatic selection and automatic layout program based on the Revit platform. This program can read the load calculation results of the space to be calculated for air distribution, and manually input the information such as air supply temperature difference, space type, air supply type and other information for air distribution calculation. The program automatically calculates the air distribution of the space and lists a variety of air outlet selection and layout schemes suitable for the space. The designer can choose the air outlet layout plan according to the needs, and the program will automatically arrange the air outlet. While arranging the air outlet, the results of the air distribution calculation will be automatically written into the arranged air outlet and the space where the air distribution calculation is performed. On the one hand, it avoids the repetitive arrangement of air outlets in the design of the HVAC system. On the other hand, it also avoids the redundant work that the air distribution calculation is separated from the model itself in the HVAC system design process based on the BIM model, so that the air distribution calculation results need to be rewritten into the model.
