I wasn't sure where to post this, but I was trying to figure out how I could exhaust two clothes dryers (not at the same time) using one piece of duct without having to poke two holes on the side of the house which is brick. I attached a schematic I drew of an idea I had using dampers. I was curious how some of you guys with multiple dryers set up the exhaust, without having all these holes around the exterior of the house. This method would use 4 inch rigid ductwork and you would have to ensure you closed and opened the right dampers depending on which dryer you used. And the dryers would be next to each other, so it's not a long distance to the exterior. I also wonder if local codes dictate this type of thing, depends on the area you are in.

hey
here is what I have done----
Buy one of these at Home Depot, under $8, remove the screen. Use duct tape and a screw or two to attach dryer #1 to the square opening. Do you see the small handle for opening and closing the vent? Use the round opening nearest that handle for dryer #2. Then you can use the handle depending on which dryer is in use. The final round opening is the final exhaust going outdoors. On one of my such setups, I have to stick a small piece of wood under the handle to hold it in place, the other stays exactly where I want it, it's all just cheap plastic.
As for local code, who knows?

Akronman,
This is a great idea. I couldn't get my drawing to attach to my post, but you understand what I was trying to do. I knew they had these things to be used for heating but didn't think of using it the way you described. Actually, I may try it out to be used for heating first since my basement is unfinished without any heat. The reviews for it says it works pretty well. I'd have to see how much humidity it adds. I guess if the windows get a lot of condensation on them, then I may not use it. Has anyone every tried one of these for heating?
Thanks

Hey Again
My gas dryers are all vented outside with no contraptions like this. My electric dryers, 4 of them, use 2 of these "dual exhaust" vents. Most of the wintertime I undo the final outdoor leg of pipe and heat the basement. I can use the extra moisture around the house, the basement can't tell the difference with more lint, and the heat helps when the basement is around 55 degrees.

We had these vent diverters for years in our house, they do add heat and are perfect if you're only doing a load or two at a time and the humidity has an opportunity to dissipate. Depending on the size of your space and other variables ( a forced air heating system will carry away humid air more quickly, etc.) the added heat is nice. The downsides are that humidity question, our cold water pipes would sweat, the windows, etc. so that's really too much humidity going into a space all at once. The other nasty thing is the lint dust. The small screen helps a tiny bit, but over time it looks as though you're flocking the whole basement like a christmas tree and the whole house on the breezes of a forced air heating system if you have one. Of course, Norge dryers did this without any add-on attachments 
you can go to Lowes and purchase 4inch metal duct in the form of a "T", usually found with heater duct parts.....and roughly in the same isle is dryer vents, and they also sell for the dryer vent, backflow preventers that go in-line for about 6.00, get one for each dryer, this will allow you to run one or both dryers without backflo into the other if one is not in use.....if you were gonna add three or more dryers in a series, you would want to go to a 6 or 8 inch vent leading out of the house.....

this is the "T"......comes in 4, 6, and 8inch or larger sizes as needed....
as for venting inside, electric dryers only!, and consider variables as mentioned of excess moisture, and lint.....you may want to use the water bucket method or create a vent box that can house an HVAC filter...just to minimalize the excess
