Résumé

In this study, the air friction from a V-shape coil bank as well as a slab coil from the coil bank was measured at a range of face velocities from 100 to 1000 FPM (0.51 to 5.08m/s) in an open environment. The angle of the V-shape’s apex was measured at 15 to 60 deg. The results were then compared with those of a slab coil. In general, higher face velocity caused higher air friction, as did increasing the apex angle’s acuteness. A visualization test showed a very different air flow direction and velocity profile on the coil’s front surface, which could explain the higher air friction from the V-shaped coil bank. These results will help improve the accuracy of fan selections in HVAC systems that feature V-shaped coil banks.
