These are all really good comments.

A small dehumidifier has all of the components to make one of these things...

Except that you'd want more efficient fans.

This would be a really interesting hack, and pretty easy, too.

There's just one thing about these units, they supply a VERY LARGE amount of air. I looked at the Combi, thinking that it would fit so nicely into a cozy, compact, space-efficient European house, then I calculated how much space it could actually ventilate, and saw that it could supply the ventilation needs for a 3500 sq. ft. house... and that's with a (quite small) 350 watt compressor, too. To be clear, that was on high speed, but that's a lot of air...

I haven't written the idea of it off, not yet... I did see a tiny cube refrigerator today at Goodwill that had a 125 watt compressor, for $25. Now that's more my size... and I have a couple of very small HXs left over from my first GSHP project...

Oh the temptation!
