Abstract

HVAC stands for Heating, Ventilation and Air Conditioning system which is utilized to supply natural air into a building. The efficiency of the system is around 60 - 75 % and it could reach up to 80% with appropriate installations and design. HVAC have a few problems which happen at the bend of its ducting which create turbulence and create vortex. This problem creates pressure drops brought on by the sudden changes in course due to the bend. To overcome the problem, turning vane was introduced at the bend areas. There are many type of turning vanes accessible in the market. Turning vanes were intended for better flow of the fluids. The turning vanes was design in AutoCAD and simulations was done by AnSys Workbench. The result of the simulations was then analyzed between single turning vane, double turning vanes with 3 proposed turning vanes design and triple turning vanes with 3 proposed turning vanes design. It was found that the proposed triple turning vanes from the first design gave a great result as far as average outlet velocity and turbulence dissipations compared to other designs. The resuIt showed that the best turning vane was the first design of triple vanes with mass flow average of velocity on the outlet of 3.19456 mls and mass flow average of turbulence eddy dissipation of 1325.16 j/kg.s.
