| description | In this study, a performance comparison experiment with a vortex exhaust installed at the end of a ventilation device to enhance the effect induced by reducing indoor pollutants was conducted. The experiment was carried out by constructing a mock-up room with a limited indoor environment, and performances were compared based on the following two tests. First, to confirm the effect of pollutant reduction, the wind speed was measured based on the distance from each exhaust system to verify the depth and speed at which wind can flow. Pollutants were induced to the vortex exhaust, general exhaust gasses were generated, and their performances were compared. Second, Arizona dust was used to confirm the performance with regard to the removal of pollutants which existed in particulate form (PM 10), and for CO<sub>2</sub> gas, a representative gaseous pollutant was used as a reference. Based on the results, it was confirmed that installing a vortex exhaust system can allow for the generation of wind speeds that allow propagation at greater depths (>110 mm) compared to cases in which general exhaust is used; accordingly, exhaust performance can be achieved at increased depths. In addition, the experiment confirmed that vortex exhaust can improve the efficiency of simultaneous removal of PM 10 and CO<sub>2</sub> compared with general exhaust. Further, it was shown that installing a vortex exhaust system can remove PM 10 and CO<sub>2</sub> farther from the exhaust port in a shorter period than a general exhaust port. In addition, it was inferred that vortex exhaust can be utilized to prevent indoor pollutants and diseases in combination with the latest technology. |
