The subject of this study is to improve the efficiency of the air-conditioning system, and to support the life cycle energy management for HVAC system of the building. And, it is considered that the HVAC system simulation tool coupling with CFD is a useful measure to realize the subject of this study.
In this paper, it is described the significance to apply the coupling HVAC simulation tool and CFD. And, the application possibility in each phase of the life cycle energy management is shown. Also, the case study result corresponding to HVAC system using under-floor will be shown at the design stage. The cooling load of chilled water was estimated by applying system simulation tool with coupling with CFD. We found out that it is possible to estimate the proper cooling load of chilled water while the distribution of room temperature is represented by CFD. Finally, the energy consumption and system COP for primary sub-system with cooling load of chilled water estimated by using the couple with CFD.
