quick thoughts would be get the coeffiencients of water to convert a water to gas.
4.16joules/something... been too long. I can get the numbers on monday when I have my physics book handy.
you need to know some other info. bring the system to equilibrium with the PC on. now you have a steady temp going in and out of the PC. take those temps.
then you figure out how much heat your removing from the system using gallons per minute. Im sketchy on this, but its doable. knowing the difference in temp in a minute you have say 100gallons of 28degree water going to the PC, and 100gallons of 29degree water coming back. using thermodynamic formulas that I have to get on monday, you can figure out how much heat was put out in a minute to heat 100gallons of water 1 degree.
make sense?
alright, so thats how much heat the evaporater is taking out of the system. to find efficiency and what not, theres another coefficient, that says it takes this much heat to evaporate this much water. so knowing how much heat your removing, you can figure out how much water had to evaporate to remove that much heat.
in a complete guess, Im betting it would take SOOOOO little. to the point where Id be amazed if you were really evaporating that much water in a month. maybe a cup or so.ignoring inefficiencies, toss a cup of water in a pot and get it boiling on the stove, tell me how long it takes to COMPLETELY boil away a cup of water, and think of how hot that flame is. takes alot of energy to evaporate water. ALOT. like 100x as much as it takes to raise water 1degree.
