Abstract:
A new air distribution pattern, air curtain jet ventilation was presented. The ventilation or airflow patterns and the air
velocity produced by air curtain jet were investigated in detail. To identify the airflow characteristics of this novel air curtain jet
ventilation system, a full-scale room was used to measure the jet velocity with a slot-ventilated supply device, with regards to the
airflow fields along the vertical wall as well as on the horizontal floor zones. The airflow fields under three supply air velocities, 1.0,
1.5 and 2.0 m/s, were carried out in the full-scale room. The experimental results show the velocity profiles of air distribution, the
airflow fields along the attached vertical wall and the air lake zones on the floor, respectively. The current experimental research is
helpful for heating, ventilation and air conditioning (HVAC) engineers to design better air distribution in rooms.
