Drawing of my furnace setup (http://www.shoplow.com/furnace_question.html)
Hi, this is my question:
Can the humidity from my humidifier pass through the a/c cooling coil? I can only install it in that area. The area beyond my A/C coil is inaccesible (under the floor).
Details:
I am about to install an Aprilaire 550 on my Bryant downflow furnace. Here is the structure of my furnace from the top to bottom:
[ ] return chamber w/ air filters
[ ] blower chamber
[ ] heat chamber
[ ] A-coil
[ ] chamber that goes to vents
I am going to install the humidifier on the return chamber, but am having a problem determining where the 6" round ductwork ("bypass connection") from the humidifier should go. I can easily run that tube down to the A-coil chamber, which is after the heat, but I fear that the humidity will condense on the A-coil rather than flow through to the vents.
Aprilaire makes the following statement:
"Do not install unit or bypass connection on a plenum face where the blanked off ends off the cooling coil restrict air movement through the humidifier"
If I understand correctly, they are saying it is OK to run the bypass to that chamber as long as the point of entry is on one of the "fin" sides of the coil rather than one of the closed ends.
If that is the case, I am alright. But if I must go to the next lower chamber (the bottom one that feeds the house vents), then I cannot do the installation. That chamber is below floor level and the water heater and gas pipes are in the way so I could not pull up the floor to get in there.
Any translation of Aprilaire's statement would be greatly appreciated!

Go for it . You have it right. If you think about it they all end up with the air going througe the A coil. If its in the top or the bottom of the furnace like yours.
If I understand correctly, they are saying it is OK to run the bypass to that chamber as long as the point of entry is on one of the "fin" sides of the coil rather than one of the closed ends.
Id say cut the hole as high as you can so you wont bend any of the fins in the coil.

I just wanted a little assurance before I start cutting holes! :)
Thanks for your input.
