Never heard of "skin venting" but sounds awefully close to what I'm thinking.Originally posted by perpetual_student
Are you familiar with the type of wall construction known as "skin venting" or "vent skinning"?
So, does this resemble your idea or not so much?
As far as I know there are not any undiscovered water leaks or other abnormalities to account for this.
Do ya think your undiscovered water leak is actually the water sitting in your toilet? hehe
Think about it... its bound to evaporate since its sitting there all day long.
Do a test and turn the water off to your toilet and flush the water out so its all dry. Keep an eye on it and see if your RH goes down.
This is of course if your wife don't mind hehe.
People speaking of these radical house designs and stuff.... I fell in love with Dome homes there for a long time. Did some work on a unit at one and the lady give me a grand tour. It was a true work of art.
Hmmm... all the puzzle peices are making full circle.
I remember one design that had the return air grille way up high on the second floor. They hiped it up like it was supposed to circulate the air better. Though that part might be true, but it seems if the air entering the A/C coil is warmer than normal.... you end up raising the surface temp of the coil. Which in turn could raise it above the Dew Point(or at least a portion of the coil since the refrigerant would boil off faster. This might be countered by using a TXV though.)
In turn reducing its ability to remove moisture.
Hot Return Air = Warmer Evap = Coil temp above Dew Point = Lack of humidity removal
The idea in the original post about
a dedicated duct pulling air from upstairs and redistributing downstairs sounds like a good way to keep the air evened out. I just wouldnt' want that to be a return for the air cond system.
