You could squeeze the fins to concentrate the airflow or widen the fins to spread out the airflow. I'd suggest never to more info focus the airflow since often, it really is unpleasant for your persons sitting down down below it.
Just A fast look on their own internet site and you will discover Many simulations for every little thing from structures, HVAC systems, warmth exchangers, pumps and valves to race autos and air planes, which could all be copied and made use of as templates for your own personal design Assessment.
Vibration isolators are adaptable sections generally inserted within the duct right after or ahead of the air handler to minimize the vibration that happens when a duct system is running.
