Evaporative Coolers - Any Experience?

As I was roasting in yesterday's 30 degree heat, an evaporative cooler (at the moment on sale at B/H for a nice price) caught my eye as an alternative to an air conditioner. Anything that cools without needing to jerry-rig an exhaust hose out the window is an interesting concept.

Do any of you have experience with evaporative coolers, either this one or other brands? Are they any good? Or just yet another appliance that is more fiddly than effective?

Any reviews, thoughts, advice would be most welcome.

As they are sending out water vapour, won't they make your room much more humid?

Wet, humid heat is much more unpleasant than dry heat.

Our bedroom is under the roof eaves and gets quite hot this time of year and I was thinking of getting a slow-revolving ceiling fan but my wife thinks they are noisy.

We have one up and another one down, very easy to use and effective in a not too large space. There is better value to be had than the one you linked to though, https://www.hornbach.ch/shop/Luftkue...6/artikel.html

Re: Evaporative Coolers - Any Experience?

The principle is that as water evaporates it cools. For my Insulin I use a FRIO which is a gel filled wallet. You stick it in water and the gel absorbs it. As the water evaporates it cools.

Similar is the system they use at Dubai airport where a fine mist of water is sprayed outside the terminal. Evaporates well before it touches the ground and it cools as it does. This is used in football stadiums as well.

You are not going to make anything cold through this process, but you can get a few degrees.

...might want to check how hard your water is, might find you get a white dust-like film on everything.

What ? You can actually hear the noise of the fan over you ?

Re: Evaporative Coolers - Any Experience?

In English:

https://www.amazon.com/Honeywell-Eva.../dp/B00IINNL9I

"Indoor evaporative air cooler or swamp cooler. Ideal for use in the southwest and Midwest regions of the US. Performs best in hot/dry climates where humidity levels are <50% "

Use the Dyson ventilator, and a life helper since last year. Cools, but definitely not silent.

They're awful and don't do anything if the ambient humidity in the room is relatively high.

I lived with one for several years when I lived in an older apartment in the states - you're better off with a real air conditioner.

A ventilator never cools.

Can only do so by heating up the room, since heat needs to go somewhere

There are two solutions.

1. Bring the heat out of the house/room, and achieve a real drop in temperature.

2. Create an airflow which gives the impression of coolness and sweat like a pig when turning it off or walking outside the flow.

Fans, moisturisers and all such are nice for moments where you yourself want to get rid of your body heat in a quicker way, as for cooling the house they do absolutely nothing.

However, a fan is still by far the cheapest (under CHF100) and environmentally friendly way of feeling cool in hot weather. Hence their use globally...

True and I had them myself, up to 30 in the house is o.k. for me, so here I do not need an airco, but I also lived in a towncenter with a flat tar roof, no shadow from surrounding buildings and no isolation and yes I loved the ceiling fan, but the moment I turned it off or walked out of it's reach I sweated like hell. Felt like riding a motorcycle and then those damn moments where you have to wait for a red light in the full sun.

Re: Evaporative Coolers - Any Experience?

Thanks everyone for your comments and suggestions.

On researching the cooler I decided it wouldn't help, and possibly would exacerbate the situation.

The novel I am reading is curling at the edges, even with the de-humidifier running. The last thing I need is more moisture in the air.

(It's dry as a bone outside, the garden is parched. How can my house still be humid?)


Did I mention I hate hate hate hot weather?

Off to stick my feet in a bucket of ice water.

Re: Evaporative Coolers - Any Experience?

@meloncollie, 2 years passed, did you end up getting any device?

I'm looking for some ideas as it's gonna be my second summer here and the studio where I work at has sun exposure all day, several window walls and it gets unbearably hot in there.

My landlord won't allow for AC installation, so I'm looking at portable unit options...
