High capacity air purification device design using computational fluid dynamics

Within the scope of this study, the performance of a high capacity (1000 m3/h) wide area (200 m2) air cleaner, which is currently used, has been improved by performing numerical and experimental studies in order to increase the efficiency, reduce power consumption and increase sound comfort. Within the scope of the studies, support was received from Solidworks 3D software in the design processes, Ansys Fluent and Ansys Spaceclaim programs, which are the Computational Fluid Dynamics (HAD) program in the analysis processes. As a result of the studies, it was calculated that the system had a flow rate of 1062 m3/h in the tests performed on the current model, and 1133 m3/h in the CFD analyzes. It has been determined that there is a 6% difference between the tests and simulation studies. The current and new product's power and flow tests were carried out, and the current product's flow rate was 1062 m3/h and the new product's demi value was tested as 1256 m3/h. According to the test results, an 18% increase in flow was achieved. In addition, as the resistance on the fan motor decreased as a result of the power tests, the current product consumed 416 watts of power, while the power consumption of the new product was reduced to 386 watts, resulting in 7.7% energy savings. In addition, in acoustic tests, the sound pressure level (SPL) of the current product was measured as 62 dB, while it was measured as 49 dB in the newly designed air cleaner with optimized no air flow. With a sound reduction of approximately 13 dB, the device is provided to operate with high sound comfort in indoor environments such as residences and classrooms.
