After much searching I was able to get my hands on a Fine Wire heat exchanger that is meant for small house or single-room ventilation. The guy who sold it to me said he had tested it an it was only good to 82% efficiency. From where I'm standing, that's acceptable.

It is the same core for the HRVs built by THIS COMPANY. They have a CO2 sensing and humidity sensing controller that actuates the fans when the need arises. I guess this helps raise the efficiency even further. I tried to buy a controller from them, but they only make 220V 50Hz controllers.

I have the HX, some fans and some ideas on how to build the fan controller. Haven't quite got the box design figured out yet.

I'll want to measure airflow for that project.
