Moving Conditioned Air Between Rooms – Science of Temperature Delta?
I know it’s nearly impossible to balance the temperature between two rooms by moving air with fans. Despite being told this, I even tried it myself once in a house that had a mini split in one bedroom with nothing to condition in the adjacent room – two ~150 CFM fans did almost nothing.
My understanding is that this boils down to the temperature delta and the fact that it takes a ton of ~71 degree air to bring the temperature of a ~78 degree room down anywhere near that. But I’m curious to learn the specifics well enough to hypothetically calculate how much air it WOULD take. I don’t expect it to be a practical solution – it’s more just about understanding the science behind it. Could anyone point me in the right direction?
