The two designs use an air velocity of 5m/s, the colours symbolize the velocity with blue indicating lower velocity and purple symbolizing the substantial velocity locations.
Even now, the above mentioned doesn't promise you a just one-time success since you will discover other things like duct length, internal cleanliness on the duct and etceteras that could affect the behaviour of the airflow. Nonetheless, it is what I’ve been carrying out for over 20 huge HVAC systems in my earlier task.
