A swamp cooler is used in dry areas for cooling. It has three main elements: a fan, a pump, and a screen. The fan blows dry air through the screen, while the pump keeps the screen wet. The water, as it evaporates, cools the air quite a bit.
How much it can cool the air depends entirely upon the relative humidity of the air. In that respect, a swamp cooler installation is different from air conditioning ... you need to have a constant flow of fresh air through the house. No closed windows here!
A swamp cooler typically will only draw a few amps.

We had an evaporative cooler in an office at work once. They had all the doors and windows open. It set the fire alarm off. When the Fire Brigade turned up, we went into the room and it was somewhat like a sauna, everything was wet, the ceiling, the fire detector. The Fire Brigade were quite bemused and slightly miffed. It lasted a few months in a larger office before it started producing an awful stench so it went in the bin.
I think it is too humid for them over here.
We got inverter A/C and I dont know how we ever coped before.
I took my time, I hurried up, The choice was mine, I didn't think enough

My father-in-laws prehistoric house has one of these swamp things stuck into the side of it, with the squirrel cage blowing straight into the living room... He had it just plugged into an extension cord, which plugged into an old floor outlet, until I showed him the extension cord was melting I hardwired a circuit in and fed a swamp control with 12/4 MC into the living room.
Amusingly, one day I went by there and turned it on to cool the house down, and this thing started blowing bubbles into the living room It did that for about a month and hasn't ever since

Swamp Cooler is another name for an Evaporative cooler. I remember working on them as an EC, you had to have a mask on while draining the water out. Legionnaires disease is rife in any Evap cooler that is not well maintained, not to mention mosquitos laying eggs in them. There was a local McDonalds was shut down because of a problem with an Evap unit here, water was like sludge when we cleaned it out. It was in the Kiddie castle thingee. One other reason why I won't eat there.
