DIY A/C, A Brief Follow-up

 I went back through my spreadsheet and found a couple of errors in the math, in both the evaporated-water and fan CFM calculations.  After correcting them, both numbers are pretty close, within .07%.  That's scary-close.  I would have been pleased to have them within 5%.  If nothing else, I would have expected the (cheap) fan I bought not to really deliver 1700CFM.

The corrections also showed that the amount of heat power being transferred is amazingly high, but water does require a lot of energy to change it from its liquid to gas phase.   The fact that a lot of heat energy is being moved around suggests that my indirect-cooled A/C setup has a chance of really working, but we shall see.
