Now we must transform the cooling hundreds into volume flow rates but to try this we 1st require to transform this to mass stream amount so we make use of the components:
It's unachievable to perform air balancing without having a radial damper or an opposed blade damper installed at Each and every diffuser and grille. Even so, if an air quantity Regulate damper is mounted within the duct department, as much as a particular standard of air balancing can be achieved nevertheless it received’t be ideal.
