All I see in the Wikipedia page is something about a heat exchanger (it looked weird, I only skimmed it but it sounds like snake oil to me.) CO2 concentration would be a chemical thing. On space ships I know they used to use alkali metal peroxides (specifically lithium peroxide because lithium is light.) These decompose into oxygen and an alkali hydroxide which further absorbs CO2 (forming an alkali carbonate.)
- sbierwagen 6y agoSorry, to be clear, the point of a recuperator is to exchange indoor air with outdoor air, reducing indoor CO2 without losing as much heat as opening a window. There's no chemical reaction taking place at all, it's just a heat exchanger.
- swiley 6y agoAh! Everything makes sense now. I guess I skimmed too aggressively.
