diy hrv help needed.
so i have read this whole thread. great info in it but it leaves me with questions. i have a tiny house. 24 long x 8 wide x 10 high. it is built by me and was done so it is super tight. it about to get cold hear and i needed a way to get fresh air in while not losing a lot of heat. commercial units are to expensive, and i'm a handy person. i got a nice size of coroplast to use as my hx core. they are 12 x 12. considering using pc high static fans to fun the unit.
based on this formula:
room CFM:
Step One – Use the above Air Changes per Hour Table to identify the required air changes needed for the use of the room. Let’s say it’s a conference room requiring 10 air changes per hour.
Step Two - Calculate the volume of the room (L’xW’xH’).
Step Three - Multiply the volume of the room by the required room air changes.
Step Four Divide the answer by 60 minutes per Hour to find the required room CFM
i get 192 cfm. that seems aweful high.
another one i found said i needed 12 cfm. so i'm kinda stuck on how big to size my unit. i feel 12x12x8 hx core would be way to big. I havent ordered any materials to start this yet. Figured i better get more info on sizes i should be going with. i plan to put the unit in a storage area i have over my bathroom. looking to use 4" intake and exhaust ports. and possibly arduino to control my fan speeds. Any help is appreciated. I see this post is kinda old, so i hope i get a reply or may have to move to new thread. thanks all
p.s i also am a vapor, so the is a fair amount of moisture in my air, but that isnt to big of an issue, as i plan to have a way to dain the hx in some way. just thought i should add that in case it changes any thing.
