Fantastic Coloroplastic
Mike has been at it again:
Quote:
OK, here's what I got...
Results
Stale hot air in 98.6F
Stale hot air out 67.8F
Fresh cold air in 66.2F
Fresh cold air out 79.0
Air flow on the order of 200 linear feet/minute >> 20CFM
Rough estimate cause flow varies all over the map depending on the position in the output stream.
Pressure in the coroplast tube was about 0.05inches of water.
There are leaks and thermocouple position issues.
But it looks promising enough to finish it.
deltaT inside/outside = 15.4F
deltaT outgoing air/incoming air = 5.8F.
Those are pretty good numbers. But the delta is small and the measurement uncertainty
is a big part of that.
After my nap, I think I'll move the second fan inside, fix the leaks, weld it together and tilt it downward
so water can run out.
Are we having fun yet?
