What do you mean by heat exchanger?
I appreciate the concepts, but is that a term or a device?

I have a super-insulated home I built so I am familiar with most of this.

The closest option I found were intercooler cores from turbocharged cars. They flow well, all aluminum construction and are some of the lowest costing heat exchangers I could find for the size. I am a machinist by trade so modifying was no big deal... In the end.. I bought a used HRV unit of appropriate size.
