Why Round? Without spiral round duct, here are a few of the things that could happen. 1. You won’t follow the ASHRAE Advanced Energy Design Guides – it’s a big deal to try and reduce energy use in commercial buildings by 30% and 50%. And ASHRAE has worked extensively to help its’ members achieve these goals by compiling research and assembling cost feedback that might be impractical. A duct system often begins at an air handler.The blowers in the air handler can create substantial vibration, and the large area of the duct system would transmit this noise and vibration to the inhabitants of the building. To avoid this, vibration isolators (flexible sections) are normally inserted into the duct immediately before and after the air handler..
