Swamp Cooler
Swamp Cooler
is a window ac more efficient than a poratble swamp cooler?
I live in the Central Valley Ca. Very Dry and HOT weather. My house does not have a ac system. I have window ac's and my roomate has 2 big portable evap coolers (swamp cooler). Which one would be more energy efficient?
To claim something to be more energy efficient than another, that thing would have to do its purpose as well or better using less energy.
Reticon (a Yahoo! Answers Asker) asked a question 
ifference between a humidifier and a evaporative/swamp cooler? I answered him with this:
We refer to window units as swamp coolers here in Louisiana. Real swamp coolers actually wouldn't cool us off down here; as an evaporative cooler the true swamp cooler wouldn't be able to cool the water in our air in addition to the water on the pads (inside of the machine). True swamp coolers use the process of evaporation to cool air. Like when you fan yourself, you are passing moving air by moisture, the act of that moisture evaporating is what makes you feel cooler. Essentially the act of the water evaporating off the pads is what makes the air cool. A humidifer (Lord help if anyone owns one down here) makes dry and uncomfortable air a little more, well, humid.
With that being said, even though you didn't ask about humidifiers you can see that a swamp cooler works best in dryer climates. A window AC uses a lot more energy because it doesn't simply cool the air by process of evaporation, it cools it off by compressing the refigerant (usually freon or some other flourocarbon). By doing this the freon becomes a hot High Pressure gas. Once its turned to gas it goes through multiple coils. As its going through the coils the heat is evenly dispersed and the freon goes from gas to liquid. Once becoming a liquid it goes through and Expansion Valve, the liquid evaporates and turns into a cool gas with low pressure. Now as a cool low-pressure gas it goes through a second series of coils while absorbing heat and cooling air. Window units have to sets of fans, one to blow the hot air outside and the cool air inside.
So obviously with more processes comes more use of energy to complete the process.
I vote swamp cooler.
Good luck!
