Abstract

A modern building has requirements need to consider increasing the quality of the building. In design the building, fresh air, cooling, and heating is the important role to consider. The Heating, Ventilation and Air conditioning (HVAC) is most important part in building. Centralized system is the common use especially in large building. Usually, the system is using diffuser for air inlet and grille for air return. Therefore, the aim of this study is to determine the effectiveness of grilles position to distribute the cool air into building. The aims of this papers are to simulate three types of location grilles for a building. In addition, the number of diffusers and grilles are same for each type. RNG K-ɛ model was used as the turbulence model. The result show that different position will affect the air flow pattern due the different position of grille
