Deflection ventilation - a conceptual introduction

This paper proposes a new mode of ventilation for indoor airflow. It uses a plate or a curvedvane to divert a jet of air directly into the breathing zone. Computational results show that withproperly selected diffuser locations and design air supply velocities, the proposed systemwould be able to maintain better thermal comfort with a smaller temperature differencebetween the head and foot level, and possibly lower energy consumption, when compared withconventional systems. This type of ventilation system has the potential to achieve better indoorair quality (IAQ) in the breathing zone but further work is required to determine if the IAQbenefits would be significant.
