Hi people,

I was thinking about the idea of reversing the flow through the heat exchanger every N minutes, to regulate the moisture content of the air. It's an appealing idea, but I could not come up with a design that does not require at least 4 actuators. 2 for switching the air supply/exhaust on one side, 2 for switching them on the other sides and a pretty clunky maze of canals. The actuators are pretty costly, especially when you buy them in a store instead of on ebay. Am I missing some clever design idea that requires less actuators?

Has anyone ever built this idea, is it applied in commercial HRV units?
