Abstract

As outdoor air quality is deteriorated by fine dust, mechanical ventilation becomes essential especially for classrooms that have a high occupancy rate. However, mechanical ventilation in classrooms may not operate for a reason that noise during classes disturbs student's concentration. The purpose of this study is to propose a control method that can keep the noise level and CO2 concentration within an acceptable range. Experimentation of the proposed control method has achieved at a university classroom of 230 m3 volume, and simulation analysis is achieved to compare the control method with a reference case. Results show that the proposed method can keep the CO2 level under 2000 ppm for classes of a duration of 75 min even when the lowest ventilation rates are adopted during lectures.
