Evaporative air coolers work by evaporating water. Humidity is the amount of moisture in the air, therefore the higher the humidity the less effective a swamp cooler becomes. Have you tried evaporative cooling towels? They should still be somewhat effective in humid conditions, especially if wet in cold water.
I wanted push the cooling efficiency of my DIY evaporative cooler designs, so I designed and built a new one (Pic 1). And it works! - I'm seeing 95%+ efficiency . (Pic 2) In particular, today, I'm seeing 14 degrees of cooling from 75F / 45%RH to 61F / 95+%RH. (pic 3) On a 100F/10% playa afternoon this should translates to 16F colder than ...
It’s not to contradict - just to provide another person’s experience, in case you’re finding those portable AC’s don’t work well for your situation. Contrary to popular opinion, evaporative coolers - aka swamp coolers - do work in Seattle. We used a $600 portable AC during part of our apartment life for almost three years, up to this ...
Definitely install an evaporative cooler however, I advise against putting it on the roof. I've been the subject of an evap on the roof. They're a PITA to maintain and since you should be changing the filters regularly (unless you get one with the thick media pads), you have to adjust the float, clean the unit, winterize, summerise, it needs a ...
According to this swamp cooler chart, at 80 degrees F at 80% relative humidity, you can drop the temperature 3 degrees. That isn't much and it would get more humid. Mold and mildew could become an issue. An exhaust fan on the wall may do more for you. Reply.
Researching different options outside of air conditioning for cooling. It seems evaporative coolers are best in dryer climates, but not sure what constitutes as dry. I come from a land of 50% humidity for most of summer. Wondering if anyone has tried one of these in their home. Just looking to cool a fair sized (around 150 square foot) room.
those are based on water evaporation. they work great in low humidity areas like Utah, but wouldn't be worth a darn in high humidity areas like Florida. Those don't work here. They cool based on evaporation, and evaporation is slow because of the high humidity. They work well in the desert. Swamp coolers work in the desert.
An evaporative cooler is basically a humidifier, it cools by evaporating water into the air. They don't work as well as air conditioning, but they use less power. They need a constant supply of water (and filters to prevent mold if I'm not mistaken). These coolers work best if you live somewhere where the relative humidity is really low as ...
We couldn't find something that would work with our windows, so when we sold it, we picked up a Hessaire evaporative cooler, despite so many people saying evaporative coolers don't work in Seattle. Well, for whatever reason, it does. It brought the humidity up from 50% to 60% and lowered the temp 15ºF.
There's a higher cooling capacity one (12000btu) for $299 which might work better for a 400 sq. ft. room. I've got one of those, too. Sure, they don't humidify the air, and they cost more than a typical portable evaporative cooler, but they're exceeding good at cooling efficiently.
