Abstract
As novel ductless ventilation equipment, a jet fan could be employed in confined space, such as underground car park and tunnel. It can provide air flow with substantial velocity profile volume which is necessary for effective ventilation. Effect of tilt angle, gap distance and height of single jet fan and twin jet fans on velocity profile volume in enclosed space was experimentally examined with 2k factorial experimental analysis. It was found that tilt angle and height of the single jet fan could exert significant effect on velocity profile volume (p<0.05). Meanwhile, in the twin jet fan system, the gap distance and tilt angle could provide significant effect on the velocity profile volume (p<0.05). In comparison with 2 sets of the single fan system, application of the twin jet fan system could provide the 142% higher velocity profile volumes with the 50% lower energy consumption.
