Swirl diffusers have angled blades to “swirl” the provision air. They may be both spherical or square in shape. Directional and spherical diffusers don’t supply air vertically. Meanwhile, linear slot diffusers don’t offer air horizontally.

Now we need to change the cooling loads into quantity circulation costs but to do this we to start with want to transform this to mass stream fee so we utilize the formula:

Nonetheless, you are able to multiply the air velocity through the duct space to get the air volume. But, It is far from the proper means of executing the air balancing work.
