Thread: The Field Lab

    Default The Field Lab

    This guy has been popping up lately in the news. He has a neat little project out in the Texas desert. One of his projects intrests me, however probably not much use here with the high humidity. Maybe could be used in the high of the dry season?

    I caught the article on him a couple days ago. I liked how the farmer neighbor gave him the cow. http://www.nytimes.com/2011/03/10/ga....html?src=dayp

    I'd reckon the "swamp cooler" could be simplified if you removed the electrical components, but wouldn't work as well. You would need a fan and water pump to get the most benefit from it. Other wise it would be some type of water drip system through a wicking material and hope for a breeze. They do make large fans that blow water mist, probably draw a lot of energy tho.

    I had many swamp coolers in CA with rentals and so on. Not much would be needed to make one. a vented metal box, gunny sacks, fish tank or wet saw pump, and a squirrel cage and some tubing, and a toliet tank float vavle to sit in the bottom and shut the water flow off when full. one end of the box will have to be used to tunnel the cool air where you want, but it could be done there. But your right about thinking it would not be so good in high humidity times, but would do wonders in the hot dry summer there. IF I were to make one there, I'd find a sheet metal shop to do the box and sides, and tunnel the way I wanted and install the rest myself. Do it all with gavlenized metal. If done correctly it would make all the difference and not cost anything hardly to run all day and all night. Manufactured ones use louvered sides, but that is to keep rain out, it could be done with holes instead and just run a cover on the top to keep a down pour out, but either way it can't hurt it.
    I never said I was normal !

    Yeah but, the Big Bend Country to which this link is dedicated, compares almost to the DAC and Just Plain John Wayne.

    The main difference is that you are in the tropics in lieu of the high desert and unlike those days in the high desert, poor ole John Wayne still deals with the Indians on a daily basis and makes one wonder as to what is goin' on?

    i am in the market for a truck, but it is not a huge deal if it comes with not being so equipped with ac. i have used a simple version of the swamp cooler as well......take a small size cooler and vent it accordingly. run a computer fan off your ciggy lighter and position it in front of a bag/block of ice. quite a noticable change in temp.

    yes, i agree with you.... can you get the humidity readings for the dry season? then compare that to where the swamp cooler works?

    A nice swamp cooler build popped up, better than the fan / bucket build. It has decent how-to instructions and nice temp / electrical numbers.

    Swamp cooler is amazing in Arizona with 0% humidity, there is reason you seldom see them in the South, and it ain't just cause the people have not figured it out.

    DD beat the swamp cooler idea to death in past posts and the general consensus was to forget it in Nicaragua .... too humid, especially on the DAC.
    Life's different here ... It's a whole 'nother pace.

    I don't think it would work either.

    We use it where we are (California high desert at 4000 feet) and it works well until the himidity rises. Then it doesn't cool anymore, but just makes things more humid and miserable.

    Arizona (where I'm headed) has a lot of monsoon activity in the summer.

    Difference in electrical cost is significant: you're looking basically at a big fan and a small water pump. Probably less than 200 watts total.

    My experiences with evap coolers:

    Calif. high desert at 3100 ft - worked fine until the temp got to 105ish, at which time you might as well turn off the pump and use it as a whole house fan.
    AZ low desert-- minerals in water made it a maintenance nightmare as the pads plugged up with salt, civilians living in house could not understand the need to leave selected windows open to direct airflow, the cost of a motor and pump running 24/7 made it more costly that one would expect.

    I would suspect that a properly sized and designed unit would be good on the western side of the country for part of the year, and useful as a whole house fan for the rest. with the assumption that the water was not overly mineralized. Also, with the Keystone Kops utilities here, use would be hit and miss and you might have to watch things like burning up the pump if the water goes out when the power is still on.

    Evap coolers are rather complicated technology for Nic., with a definate training curve for things like adjusting the float level. Imported tools like screwdrivers would have to be obtained, maintained, and guarded.

    My 500 square foot office has a whole house fan mounted in the ceiling, in the bathroom. It makes things bearable in hot humid weather, if you're going to just sit at a desk, and your body is acclimated to heat and humidity. But it's noisy as hell and a small desktop fan does about the same job. A ductless mini split A/C does the best job, but you are totally disconnected from nature that way.
