I am posting this info to potentially help anyone contemplating a conversion to mini split. I measured the CFM flows coming from the existing SCS units in our coach with fans on high.
The combined CFM on the front unit was close to 500 CFM.
The combined CFM on all the vents from the rear unit was close to 500 CFM.
I say close because there are lots of factors for getting a super accurate number, and these were crude measurements. But they should give you a number to compare to when looking at flow rates of ducted or cassette units.
I realize this is somewhat apples and oranges give the generally accepted wisdom that less BTUs are needed with mini splits, and that most mini’s run at much lower CFM because of virtually continuous operation.
As I think through how to do this on our rig, inquiring minds wanted to know. :-)
