Flow characteristics, mixing ventilation for heating

An air jet can be discharged from a nozzle or an orifice. In both cases, once the air is discharged from the duct, the diameter of the air jet increases and the velocity of the air decreases as the jet penetrates further into the space that is being conditioned. This phenomenon is responsible for the heating and cooling that occurs. Depending on the season, the ambient air is cooler or hotter than the air jet. This air gets drawn in and in doing so gets heated or cooled as it makes its way to the occupied zone. Another important aspect of this phenomenon is that the air slows down once it is discharged from the duct. At FabricAir we quantify this phenomenon and are able to size our NozzFlow, JetFlow, Oriflow, and many more to achieve the throw that you want.

FabricAir dispersion systems are fully customizable and can be tailored to your specific needs.
