Jet Fans for Parking Exhaust Systems
Jet Fans for Parking Exhaust Systems
(OP)
Dear All,
I am working on a project of basement exhaust system I have proposed the conventional ducting system but the client wants jet fans instead of ducting I dont have any idea can any one help me out?? any calculations? any materials ? sources?? case studies??
Regards,

Impulse or jet fan: An axial fan with a high velocity discharge that induces air flow in a long underground tunnel without ductwork

As for calcualtions, that will be code based. Ususally low exhaust during normal conditions, and a higher rates of exhaust when carbon monoxide levels get high. (something like 1.5 cfm/sf from memory).

Can you tell how do i place them? i mean positions of jet fans, should i place them at the points where i have placed diffusers or place them in such a way that diffusers come in between??

Exhaust rates will be per ventilation code (Ashrae 62?)
As for location, it all depends on the layout. Assuming large rectangular box? Intake on one side and exhaust fan on the other? Or am i oversimlifying it? If you use a jet fan underground and dont duct it, how can you push air above ground and outside? And if you bring in outdoor air as youyr intake how do you condition it.
Just because the client wants it, doesnt mean he knows what he wants or what is good for the buulding (or of ot meets code). What is the reasoning for the jet fans? Is it cost? Im sure with minimal duct and less expensive type of fan, you can provide a less expensive option that will work better.
It is your job as the engineer to provide hime with that info.
