I'm venting an AC to the Garage. Since I'm renting

what the fucking fuck? so you gonna cut a hole in the garage door window to vent the ac. and now want to rig some crappy ghetto system to hold the duct up when the door goes up... jesus thats stupid and so is your landlord.

Why is everyone here so negative? It's a simple question. He's going to have a mechanism that will remove the ducts from both sides when the door goes up, and he's going to use a pneumatic system that has15 psi to do that.

Then when the door closes, it will take more force to re-insert the ducts from both sides, so he's planning to use 25 psi for that step.

He's open to suggestions, people. So far it looks fun and workable. It might take a year to design and debug the robotics, with a cost of maybe 100k not including the mobile structure to move the robots in and out of the way.

It's one of the coolest projects we've seen in years guys, lets pitch in and make it work.

Hahah thanks.

I was actually looking for more of a "Hey, here's a solution that exists that may be what you need!"

>>1213317
Dude, seriously? Go back to /gif and complain about the porn.

>I was actually looking for more of a "Hey, here's a solution that exists that may be what you need!"

I actually tried to answer what you appeared to describe.

Draw a sketch showing and or describing:

1. the airconditioner

2. where the duct goes to

3. where the duct comes from

4. where all this shit is going to go when the door goes up.

5. what the psi shit means to you

The more detail, the better. So far I have no fucking idea what you are trying to accomplish.

I left one out: what does "venting an AC" mean?

>>1213176
so what is the cfm output of said air conditioner?

>>1213176
>venting AC to garage
whut?
AC is a closed system anon.
You tap into the supply side and return side.
Venting to the outside won't do anything but let bugs in.

>>1213372
Unless you are talking about a floor mount AC unit like these

>>1213373

You might be onto something.

Got any idea what he meant by this, with his "measuring tape" system?

>I want it to automatically pull the excess duct up with say, 15 psi. Then, as the garage goes down it pulls out with say 25 psi.

Maybe he's confusing pressure with force, not to mention that first the duct goes up but then it goes out.

I wonder where exactly the AC unit is? Did the landlord let him run a duct through the wall, or does OP actually live in the garage.

So many questions...

If you're lucky

Bad idea, but I'll give you my blessing.

Winch or a Coil look through some options on blinds. I'm thinking you might have to go more industrial but I can't tell without a drawing and some weight measurements.

That's a retarded idea. Why wouldn't you just join it to the dryer vent? Connect it using some sort of Y connector.

>>1213176
I think I got the general idea of what you are trying to do. There are brackets made to hand shit form the outside of garage door tracks, hang something like a long curtain rod, I'd say metal electrical conduit is your best bet. Brackets support it from the ends. Use shower curtain hangers that have the rollers and keep something like silicone spray lube on them to make sure they slide with minimal drag. Hang flex duct from shower curtain hooks with a little mechanics wire. Just use a few of the curtain hooks so there's lots of room for loose flex between them whether the door is up or down. If you want it to actually retract/compress and not just hang looser when the door is open, you could use a retractable clothes line, it's what you want that acts like ID or key holders, except you might have to take it apart to remove a locking mechanism that is meant to keep it extended temporarily. Thread that retractable clothesline through the curtain hooks, attach the other end to the door near your vent hole. when door is down, hangers and flex duct are spaced and tight, clothes line is extended. when door goes up, clothes line retracts and pulls loosely hanging flex duct back towards the mechanism, making the flex duct shorter, looser, more compacted.

Or, just mount rigid duct from door track so that it is close to the hole and have some rubber foam or paper funnel/gasket thing that lets the door vent loosely mate to the duct.

More pics would definitely help.

The conduit rod would have to start hanging from the track near the door, then the other end past the end of the track, so that there is room on the makeshift curtain rod to hold the crumpled up flex duct retracted when door is up.
Heres a pic related crap attempt at a design from out of my ass, enough to get the general idea through so that you can look at the site and see if it'd work.

Okay, yeah, now I see what's going on here. The Right Way(tm) would involve exhausting the air conditioner through a roof chimney, but if the landlord is opposed to that, I suggest running your exhaust pipe down the middle of the garage. You then add a spring-loaded hinged plate on the door itself that slides onto a strike plate attached to the garage door frame, to which you attach your exhaust pipe. Bad drawing related

The kind of no AC calls that make me want to quit

>>1213506

>turn dryer on. hot air is forced back thru the duct to the ac unit causing it to not work and overheat
>this is surely a good idea

just. shutup

this seems like an over complicated bullshit solution. just dril a fucking hole in the side of the garage wall and vent it out. tell your landlord this is a more viable solution than rigging some faggot ass duct cut into the garage door, and on a suspension/hydraulic system to move the duct out of the way. you are over complicating a simple thing.

>there's no way to install a backflow prevention flap
>my idea isn't over 9000 times better aesthetician and technically than OPs brilliant idea to cut a hole in his garage door

>>1213176
Just go out through the wall you fucking moron.
