Author :Ahmed Elgendi, Shahin Heidari, Abhijit Date

Abstract : Modern commercial buildings consist of some sophisticated systems such as HVAC technology that delivers thermal comfort environment to all occupants, which is based on thermodynamic principles. This paper investigates a new indoor airflow closed system strategy defined as non-directed airflow and its significant improvement on the some of the main factors (temperature uniformity – air movement) that determine the thermal character of an indoor environment. The main aim of this study is based on comparison between the new approach and the conventional systems throughout conducting a series of CFD (Computational Fluid Dynamics) simulations with changes in boundary conditions, various inlet air velocities and different outlet air scenarios. The multiple outcomes would quantify the improvement of thermal comfort conditions, and the graphical results would exhibit the advantages of the new indoor airflow mechanism such as the uniformly distributed temperature, elimination of short circuits and local drags by decreasing air volume, and the reduction in fan speed. Sequentially the novel airflow mechanism could potentially result in a significant reduction in ventilation and cooling in energy consumption. Keyword: HVAC Non-directed airflow, Indoor airflow CFD simulation, - Pressurised ventilation system - Thermal comfort conditions.
