Induction Terminal Units
Induction Terminal Units
(OP)
Does anybody have experience in these units? These units have a venturi tube section (Bernoulli effect)that inducts in return air without an assistance of a fan. I am designing one and have a question on how to calculate the induction velocity versus the static pressure drop through the venturi tube?
Example: If my static pressure upstream of the tube is at 8"wg and downstream of the tube is 7"wg, the pressure differential creates a local vacuum and inducts air into a secondary opening. What would be the velocity of air as it enters the opening?

They have different nozzles for different pressurs. From memory you can get 2:1, 3:1 or 4:1 return air to primary air ratio, depending on the upstream pressure.
