Tóm tắt

This study focuses on developing BIM Tools to support the design of HVAC (Heating, Ventilation, and Air Conditioning) systems and simulate temperature distribution in rooms based on the BIM model. The research team successfully developed a BIM tool on the Revit platform using the C# programming language and the Revit API, automating the placement of Cassette-type indoor unit according to two criteria: cost optimization and thermal comfort assurance. In addition, the study applied CFD (Computational Fluid Dynamics) simulation to assess temperature distribution and air velocity in the room. Simulation results show that thermal comfort indicators such as PMV, PPD, DR, and VATD all meet the standards TCVN 7438:2004 and ASHRAE 55-2020, confirming the effectiveness of this design. These results not only demonstrate the feasibility of integrating BIM and CFD in HVAC design but also open new development directions for the construction industry in Vietnam.
