Study on application of highly efficient ventilation system to improve air quality in smoking room

An investigation to understand the actual conditions of smoking spaces was conducted, and it became clear that the introduction of a highly efficient ventilation system is necessary in addition to the securing of a sufficient ventilation volume. In addition, case studies using CFD and experiments were conducted on the effects of introducing a highly efficient ventilation system to smoking rooms. As a result, a unidirectional ventilation system with a floor to ceiling airflow, such as a vertical swirl flow system, is highly effective for the improvement of the air environment in smoking rooms, when compared to ordinary mixing ventilation systems.
