Abstract
Ventilation systems can ensure the required minimum airflow to remove humidity and air pollutants from the building and maintain an acceptable Indoor Air Quality (IAQ). While determining these airflows, the type and the location of the supply and exhaust air outlets are less thoroughly investigated. As a result, the local ventilation effectiveness remains mainly unconsidered.
In this work, different types and positions of supply and exhaust air outlets for a living room were explored. The ventilation effectiveness of these systems was determined using computational fluid dynamics. The results indicate that an optimally distributed supply air makes it possible to improve the ventilation effectiveness. This leads to an improvement of the IAQ in the occupied zone or to a potential supply airflow reduction. This reduction has a positive impact on the energy demand of the air conveyance and air treatment subsystems.
