Transfer fans from hallway to bedrooms
I’m looking at a few different heating and cooling options for a (very) efficient two storey house with no basement. An option I like is using one ductless minisplit air handler per floor. Simple, inexpensive, fairly easy to size properly, pretty efficient.
My question is this: is anyone familiar with (or have an opinion on) using small through wall fans to transfer air from a hallway to bedrooms? I’m picturing two fans. Possibly, one near the ceiling and one near the floor, on a single switch. One fan would transfer air from the hallway, one would transfer air from the bedroom. To get fancy, they could even be reversible (heating season and cooling season).
Kind of like the Lunos concept, without heat recovery.
I think the National Research Council (of Canada) may have tried something like this, but I haven’t been able to track it down.
