AIR FLOW CONTROL VALVE DEVELOPMENT WITH REINFORCED OPERATING PARAMETERS

Abstract

Recent research has shown that particles in the air and harmful gases in the environment increase the risk of various respiratory diseases and mortality rates. For effective ventilation, particles and harmful gases in the environment must be captured before they are released into the environment. Air flow control valves (AFCVs) play an active role in the capture of particles and harmful gases in the environment with central ventilation system. In the study, an innovative AFCV, which is the most critical part of central ventilation systems, has been developed. Performance criteria in the innovative AFCV design have been the capture rate, the flow rate and turbulence intensity. In this study, six valves are designed as an alternative to the current valve. The designed valves were mounted on the central ventilation system hood and numerical analysis was performed. ANSYS Fluent software was used for the analysis. The best and worst valves were determined as a result of numerical analysis. Prototypes of the determined valves were created and experimental verification tests were carried out. Again, numerical analyses simulating the experimental tests were performed with these two valves. The experimental test results and numerical analysis results were compared. As a result, due to the innovative AFCV design, the air flow and the capture speed have been increased and the turbulence intensity has been reduced.
