I am *by no means* an aerodynamics wonk. However, I have had a similar discussion with my husband, who isn't an aerodynamics wonk either but tends to have a better grasp of physics and engineering than I do, and he says that the answer is Not Really, on account of the pitch and shaping of the fanblades being designed to maximize how well air is pushed in the 'usual' direction, at the cost of reduced performance when running in reverse.Nifty said:I also like that it is reversible... speaking of which: Anybody a master of aerodynamics? Everything being equal (i.e., other doors / windows being open) would a fan "pulling" air from outside and "pushing" it into the house (and out other windows) move the same volume in exactly the opposite path / direction as a fan "pulling" air from inside and "pushing" it outside?
You should find an actual aerodynamics wonk to check with for *sure*, though
Also you should consider that it might be a bad thing to run it in reverse (blowing into the house) in a normally furnished house unless you want all loose objects less than 20 lbs to get jetted to the far end of the house or the nearest window <g>
BTW, thank you for the link to the product -- I did not realize there was something like that on the market (powerful window-mount fans), and I think I may have to see what's available in that genre up here, as the house gets real hot during the day but the outdoors always cool off well in the evening... hmm...
let us know how you like it!!
