I'm a little unclear about that process, too. When a swamp cooler has hot/dry air blown through it, it cools that air that went through that wet medium via evaporation, yes? When sweat on skin evaporates from 120F hot/dry desert air moving atop it, if that vapor created then is cooler than...

Assume a nearly full length thin robe open at top and bottom and largely, somehow, held off a couple inches away from bare naked skin underneath to maximize unrestricted vertical airflow. Assume desert 120F hot and very dry air can enter/exit at either bottom around ankles or at top around open...

I just now came up with 0.02192 ounces of condensate water per cubic foot by using this chart... http://www.process-heating.com/ext/resources/PH/2001/05/Files/PDFs/0501PHhartzell-tables1and2.pdf where I took the water content of 90F 80%RH air and subtracted water content of 40F 100%RH air. Not...

Per cubic foot of hot 90F humid 80%RH air, how much water is released when that air temp is dropped to 40F? Thank you for any comments.

Many of the commercial and larger restaurant ice makers require that water temp pumped in for making ice needs to be 45F or higher. Anybody know why? Seemed like the colder the better, this side of freezing, everything would run more efficiently. I'm guessing it's cause however it's piped...

Unit above mists out forcefully to over 25 feet and 95% of its output is less than 50 microns, most around 20 microns, so it'll evaporate readily. Can be dialed down to about 1.5 gallons per hour. I'm thinking if I did try this, I'd have first channel be a long straight shot for it, before first...

Got one of these, might play with it, was wondering how it might work as blower/mister all in one and it's an adjustable output, of course would need larger water feed...

The evaporative cooler would be outside attached to sidewall blowing directly into beginning of baffle space with provision to slide a blocking board at connection point to seal off air infiltration into baffle when not used. Also, if inside baffle getting too wet too long seems to create an...

NTL2009, exploring pipe-in-pipe counter flow utilizing the evaporative cooler there, too, just wanted to see what might be expected from 300 sq ft flat plate heat exchanger idea. Like to know how much Delta T I need to make it worthwhile fooling with. Fortunately, it's not hard or expensive...

OK, gotcha, will research that out well before acquiring, thanks!

I was thinking more of the type that pump water to top of pad, and just turning off pump, but I'll definitely be looking to capability to somehow bypass water when selecting one.

Good on both points, thank you. Maybe to reduce mold risk, I could run it for a few minutes without water before turning off and leaving for the day, that should flush and dry it out some if humidity still in low teens when I did, yes?

For a 300 sq ft workshop that you'd not want to add humidity into directly with a swamp cooler, what if you made instead a 4" false ceiling of 2x4's on end, covered with thin plastic sheeting of minimal r-value, to blow cooler evaporative air through a serpentine baffle configuration to achieve...

Yes, insulated chilled water just for greenhouse cooling. My battery of 'coolth'. Sent PM to minimize thread drift here about BTU figuring, but no, too hard to figure.

NTL2009, Essentially, an off grid PV solar powered compressor driven freezer containing 2,750 gallon water tank to start, that can have capacity easily/cheaply doubled or more later, as seen needed. I'm encasing that water tank of less than 400 cubic feet in, like new, salvaged 5" thick...
