摘要：

This work lays the foundations for improved thermal comfort in climate-controlled rooms. A methodology is developed which makes it possible to estimate the airflow process in real-time. Based on mathematical modeling, the air temperature and velocity are calculated by virtual sensors at deliberate positions in the room. Therefore, a computationally efficient, data-based airflow model is developed. The benefit of the new virtual airflow sensors is demonstrated by controlling the Predicted Mean Vote (PMV according to ISO 7730 standard) in a real conference room.
