A lilttle confused , Newibe

[mrclubguy]

Ok so Iam getting ready to open two night clubs in dc and i im trying to engineer an airflow system what theguy wants is a system that blows retalively high pressure air on to people who are dancing or at their tables that can be controlled remotely of from a contorl panel on the wall .
So im just fishing around to see if any one has ever done something like this or could help meout . He wants it to be seperate from the ac and heating units. Kinda like the overheadvents on the air lines .

Sounds like to totally seperate 'spot cooling' system. You could try an inline fan in the ceiling space (or whereever you have space) with a VFD. Size the diffusers to have 150 fpm+ at design conditions on the dancers. VFD panel to slow the fan down as required.

Variable speed ceiling fans might be an idea as well.

You should tell him to hire an Engineer......this is Public Assembly space and fraught with liability.

What you wants sounds easy until you try to do it.

I would put the jets in the table tops and the bar tops, shooting up. Be like Marylin and a subway vent

Take the "V" out of HVAC and you are left with a HAC(k) job.

I would install a E.C.M. motor on a supply fan with a remote controller that can be installed anywhere you like.You can set the amount of air flow The motor is programmed to provide constant torque. Or simply put, if static pressure changes, the motor program will only maintain the amount of programmed torque. This should not be confused with constant airflow. Even though the X13 can maintain torque, if static pressure increases, airflow will decrease, similar to the PSC motor curve shown above. However, airflow will not decrease as poorly as a PSC motor, since torque is being maintained.The limitations are that it is only good for up to a 1 HP motor and 2400 CFM
