HVAC Analysis of International Airport
Solution:
A leading infrastructure enterprise partnered with us to measure the performance of their HVAC system designed for the international airport through Computational Fluid Dynamics.
The drawings provided by the client were converted into 3D CFD model including the equipments, shops & offices within the building. Heat loads for the same were determined to replicate real thermal conditions including the long people queue situations. The effects of glass roof, doors & windows were also taken into account to measure the addition of heat inside the building.
Boundary conditions for the inlet and outlet air flow were applied along with suitable turbulence model to calculate velocity and temperature distribution inside the building. Critical regions with higher air velocity (above 0.2m/s) and temperature (above 260C) were identified through post-processing to measure the efficiency of the supply air outlets (Binnacles). The results suggested a need of changing the placements of binnacles and also reducing the supply air temperature to maintain sufficient thermal comfort within the building.
