I'm not aware that anyone's tried this yet. Seems easy enough. Why don't you?


Really?? You don't think anyone who lives in the SW has tried using
evap to cool their homes???

People who use evap coolers know how much CFM is needed to be
comfortable on a 110 degree day with humidity of 20%.


How much, for a house with a 128 Btu/h-F conductance?


For a house of about 1200 SF you need at least 2500. For a large home
you'd need to go to the 4000 or more. And the 128 Btu/h-F conductance
doesn't mean squat. Once you start using an evap cooler you
generally run them pedal to the metal during the day once temps are
over about 93.487 degrees F. If things cool down at night you might
run them on low speed then and at the beginning and end of the summer
when it's not real hot. But as soon as you start pumping all that
humidity into the air from the EVAP you need to keep a lot of air
moving or it becomes stifling regardless of what the thermometer says.

You're like the theorist who can "prove" that bees can't fly.
That guys theory was inadequate, just as yours seems to be.
