Abstract
In large space and span building, secondary airflow with nozzle's jet could be used to improve the uniformity of temperature and velocity distribution of indoor thermal environment, as well as the occupant's comfort in the occupied zone. Therefore, it is very important to reveal the characteristics of the secondary airflow equipment with nozzle's jet. In this paper, the characteristics of secondary airflow equipment and its air jet were researched through experiment. The experiment results on secondary airflow equipment performance showed that air volume, air static pressure, power and sound pressure level of the equipment would increase along with the increase of rotation speed under the same air nozzle diameters. And the results on air jet track illustrated that when the horizontal distance increased, the axis velocity of secondary airflow decreased both in isothermal jet and non-isothermal jet conditions. Through this experiment, the characteristic parameters of the secondary airflow equipment were provided for actual construction design.
