Indirect evaporation involves moving two streams of fluid instead of one, which needs an extra fan/pump, so it tends to use more energy (electricity). Artwork: How an evaporative cooler works. 1) Hot, dry air is sucked in through a grille. 2) The air passes through a pad soaked with ...
A swamp cooler, or evaporative cooler, works by drawing warm air through water-saturated pads. As the warm air passes through the pads, water evaporates and absorbs heat from the air, resulting in cooler, more humid air being expelled into the living space. ...

Dry conditions are ideal for using swamp coolers. Since the point of the evaporative cooler is to use water evaporation to cool the air, you need dry air for it to work. Humid conditions don't allow the swamp cooler to lower the temperature like it can with dry air. That makes swamp c...
My cabin is small. I figured that only a fairly small swamp cooler would be needed to lower the temperature inside the cabin to something comfortable during the hottest part of the day. I wanted to build one that would sit on an extended window sill and pull in outside air and cool it...
It would be interesting to build a swamp (evaporative) cooler for a dog house, to use even less energy. tedcapote14 years ago Flag Not nice Inappropriate SpamReply Good for you doggy you've just got an air conditioning system on your house lol warzhammerz15 years ago Flag Not nice ...
Other “hybrid” designs, such as the Marley NCWD Cooling Tower, function like a wet cooling tower with an additional dry section installed parallel to the traditional heat transfer media. This allows operation in either evaporative-only or combined-wet/dry mode, to limit water evaporation and pl...
One simple solution is to build your own pot-in-pot fridge, using basic pots, sand and water. An idea revived by Mohammed Bah Abba, this refrigerator is now being used by many farmers in warm climates who need to preserve their food for a longer time and keep the insects away.[1] ...
This leads to a higher concentration of water vapor in the atmosphere. In cooler climates, the air holds less water vapor, resulting in lower humidity levels. That's why certain places feel dry and others feel humid, even at the same temperature. What Relative Humidity Measures Relative ...
You can also choose a unit that doesn’t require venting at all, such as an evaporative cooler. The key is to ensure hot air isn’t recirculated into the room you’re trying to cool. Do You Have to Put Water in a Portable Air Conditioner? You don’t have to fill in a standard ...
