Ventilation for tobacco smoking - A case study -

The aim for the design of the ventilation was to achieve the best possible air quality in the non-smoking zones and for the employees in a combined bar/restaurant. Air curtains are used to separate the zones. The experiment proved that the air curtain is vulnerable to temperature differences between the curtain air and the room air but stable conditions have been achieved.. Nicotine concentrations have been measured too. Tests showed that smoking in the non-smoking zones leads to nicotine concentrations above the target levels.
