Hello! First time poster, long time lurker (on this thread anyway).
I'm toying with making a counter-flow HRV as a hobby project for a finished backyard office/studio/workshop (~1050 cu. ft.). How does one go about sizing the core itself?
Pictures show a Sketchup model of an 6"x6"x32" counter-flow core made out of 4mm coroplast, which would use just about exactly one sheet (including strips). I'm not sure if that is too small to be effective for this size space. If I was doing the math right, maybe 80-90 CFM for this space?

Segment View. The center support strips are probably unnecessary for this 6x6 design... it started out as 10x10.
