1080w led room air problem

[kollos]

And i have another question about this outlet problem, if i make a third room, 100% sealed, what happens if i take my outlet fans and force them in there? does this work? do the air vanish in the sealed room? or does it freak out on someway? the fan is blowing 24/7 so it cant come back, where do it go? haha. Thanks guys where soon there

Buy why aren't you using a fan and exhaust hole for every room?

and to answer last question, if you would exhaust air into a "sealed" room, it would not be sealed anymore.
also, air that enters needs to also exit. that is why passive intakes work. The exhausted air generates a low pressure in the room, so air is taken in throught the intake hole(s).
if you pump air into a sealed room, something will break down. either the room walls, or the fan that pumps air. even if the fan would turn the blades, air can't enter if it doesn't have where to go.

Because its inpossible for me to have (4) inlet and (2) outlet holes from this room, its just inpossible for diffrent reasons.

 

[kollos]

Because i need double size intake as outlet.

And i have (1) 4" outlet from both rooms then.
That means i need (4) total inlets, thats 6 big 4" pipes in a wall

 

[kollos]

The only way i can do this is if i can force air into a third 100% sealed very very small room, does the air inside this third room vanish by itself?

how many pipes do you intend to put in total? what about using bigger diameter pipe?

already answered that last question.

Okey im totally with you my friend.

The problem is i cant answer your question, i just took 4" as a messurement because my fans have 4" connections, and assumed i needed 4" out and then unfortunally double 4" for inlet, EACH ROOM.

and this makes it total of 6 4" holes.

i dont know how many holes or sizes i need to be honerst. i just assumed that both fans want the connection size pipe as their standard outlet

220m3/h in cfm is 130, and 280m3/h in cfm is 165 cfm. Either one is a high volume for a 4" pipe. Combining them will give you 260 or 330 cfm. At 260 cfm, you are into a 6" pipe normally.

 

[kollos]

If i make (1) 4" inlet to each seperate room, (2 inlet total)
And (1) 4" outlet from both room tru a Y split.

How do i know if this outlet is to small? Maybe it works perfect to get the air out from both rooms in this outlet?

 

[exploziv]

if you use them separately, using same pipe diameter as the fan exhaust is ok.
if using a Y to connect 2, as rives said, you need 6 inch diameter pipe from the Y to outside.
If using a 6 inch diameter pipe with the 2 4 inch fans feeding it for exhaust, you would need 2 x 6 inch diameter intake hole/pipe, one from each room, for intake.

Oh i see! this is crazy, now im up to (2) 6" inlet and (1) 6" outlet

how will i ever solve this big holes

 

[kollos]

You guys are so damn nice for helping me, u deserved a good gift from santa this year x)

 

[exploziv]

In what material do you need to make the holes for the pipes?

 

[kollos]

Concrete. and stick all this pipes out, and lead them underground 3-4meters away. its a pain in the A.. Plus i get 3 big 6" holes in the wall dosent feel good at all to totally smash the basement wall

what about calling in profesional help to install a small venting window or some kind of vent panel, then go and modify starting from there?

This options are not possible.
I need to get pipes inside and out.

But i will think about this alittle how i will sort this but can you please give me a last verdict?

(2) 6" intake and (1) 6" outlet connected to both fans 4" pipes.

But if i want to go by the 4" then i need, (4) inlet (2 each room) and (2) outlet (1) each room? based on my fans.

Can you count on the low speed because if the fans is enought for my space i would love to run them on low, the rooms are 80cm*2meter

What is the cons of to much air in and to little out, and whats the cons of to much air out and to little air in? so i know witch way to be safe that its good

 

[exploziv]

Yes. you need 3 x 6 inch diameter pipes or 6 x 4 inch diameter pipes.

We need full dimensions for volume calculation. L x W X H

You can't have too much air in or too much air out. Same air volume will enter and exit the room, or if the air is pulled out or pushed it at a greater power than the walls will hold, room will either implode or explode from the pressure difference.

Im very sorry for this crazy European missunderstanding, i thought 6" was totally diffrent! my fans have 125cm outlet (i guess its 5"?), so 6" is only 150cm, thats waaaay less then i thought in my tired head, i thought 6" was about 30-35cm.

So its no problem! i get so happy now i missunderstanded it.

So (1) 6" to each room inlet.
And (1) 6" outlet coming from each 5" fan connection from a Y split? will this be freaking awesome ?

 

[kollos]

I imagine 3 holes with the area of 35cm belive that vision drilling the wall down for 3 holes of 35-40cm area hahaha. im dying here
