BIM automatic optimization layout method for HVAC refrigeration rooms based on improved particle swarm optimization algorithm

By using a programming mode that combines Revit API and MATLAB, an effective secondary development on the Revit platform is carried out, thereby achieving automated layout design for equipment in HVAC refrigeration rooms. This not only effectively generates equipment layout plans, but also supports preview and verification of layout plans, significantly improving the design efficiency and accuracy. The innovation of this research lies in a successful combination of particle swarm optimization algorithm and BIM technology, providing a new perspective for automated design of HVAC systems and verifying the application potential of BIM in forward design in the HVAC field.
