Botswana Innovation Hub Auditorium - South Africa
Comparison of Conventional Cooling System and Underfloor Cooling System
Conclusion
Thus 2D CFD Analysis was carried out to compare the efficiency of the cooling system of auditorium with conventional cooling system vis a vis underfloor cooling system at Botswana Auditorium. It was found that in the conventional system the temperature at the occupied area was in the range of 25-29 degrees in the auditorium whereas the temperature at the occupied area using Underfloor cooling system was found to be in the range of 23 -24 degrees. The temperature at various planes in the auditorium was found to be high in the conventional system rather than the underfloor system. The air velocity in the human occupant area was also found to be in the comfort level in Under floor than the conventional cooling system. So the auditorium was recommended to have an underfloor cooling system rather than the conventional system.
Objective
The main objective of the project was to conduct a 2D CFD study to compare the efficiency of the cooling system of auditorium with conventional Cooling system vis a vis underfloor cooling system.The project was the Botswana auditorium in South Africa which can have an audience of 250 people.In this the CFD analysis was carried out with two cases.In which the first case was with overhead supply and extract near the stage surface. In the second case the supply was from under the seat and extract was at the roof level. The CFD analysis arried out to see the distribution of the air & temperatures inside the auditorium in both cases and implement the efficient cooling system for the auditorium..
Modeling and Analysis
2D CFD model of the auditorium was created and appropriate meshing was given to the model. Then appropriate boundary conditions were given to the model. In this auditorium the total heat released by 250 people in the auditorium and 10 people on the stage is 20,020 watts of Sensible Load and 10,920 watts of latent load. The total lighting load was 4710 watts. Few assumptions were also considered like the inlet velocity from the diffuser was assumed to be perpendicular to the surface of the diffuser,the coanda effect and 3D flow effect are not simulated.The radiation heat load from the lighting sources has not been modelled.Moreover the relative humidity was also not modelled. Using these assumptions and boundary conditions the CFD simulation was carried out for the auditorium.
