Not excluding the massive amount of regarding this post..

But:

d duct

What is D Duct?

Is that similar to "B-Vent"?

[The Doctor]

Isn't axial type fan d kind blows air upward not outward?
What size d duct? Any booster fans installing?
Did you skip d grammar classes? Take d ritalin and call in d morning.


Hi nd, and could i welcome you and ask if you could include an exhaust fan in the duct work on aux contacts with the cooling? or d cooling? We do not use auxiliary fans at all with smaller units doing the same thing, but it probably would require a certain size duct, and I am not d man for d job.

According to TABB ( Sheet Metal and Air Conditioning Industry) a propeller fan should not be connected to any duct work because the resistance of the duct increaces fan BHP unlike a centrifugal type fan.

I have installed a temperture controlled exhaust fan that kept a room cool and let the condensers run normally.
