Found this today on line. Only new and not yet available in WA for a month or so.
Anybody care to comment on the claims, and has anybody yet installed one of these. If so, how did it stack up.?
NOTE: not suited for high humidity area's like NT and Queensland.. apparently
Sorry about the American demo guy, but you get that

Hmm, Very interesting.
Never heard of them. But,..

The idea looks good.
Basically it's juat an evaporative aircon with a heat exchange system so the evaporated water vapour is not blown into your house, but the coolness which came from the evaporation process is blown into your house.
This seems like a good idea because one of the drawbacks of evaporative aircons is that if the outside air is already a bit on the humid side, as it sometimes is near the coast, then by adding a bit more water vapour to it, the air inside the house, although being a bit cooler, actually feels more stiffling because of the high humidity. This system gets around that.

I think the science looks good and the claims they make seem reasonable.
The only thing I might be concerned about is that he didn't mention any self cleaning mechanism for the wet pads.
Anything which evaporates water off it will clogg up with muck from the water in a few days and will need to be flushed.
Maybe they have this covered and didn't bother to mention it.

I think you should buy one immediately and let us all know how good it is.
Tell us where from and how much if you find out.

Actually, my place is all set up, I built with high ceilings, and fitted one of those juice guzzling reverse cycle jobs but it is rather nice on a 41 degree day, or a 35 degree night

My Son is about to start on the "build" his third family home, with the normal buy develop sell scenario. I found this on the web when he asked about aircon.
Will be interesting and now even more so, with you raising the cleaning of the pads maybe an issue. Might slow its potential down a tad,with the stuff we have in our water over here.

Mineral,
These look like they work on the same principle as those ubiquitious evaporative coolers that are used out in western Queensland - albeit somewhat quieter I suspect. My in-laws house in Longreach had an evaporative cooler which worked beautifully on really hot dry days but was relatively inaffectual on hot humid days when storms were around. I'm not quite sure, but does Perth get fairly humid or do your really hot days come predominantly off that big desert to the east? Anything that only uses 600watts to cool air efficiently can only be a good thing.

if you have a local breeze then passive design will mean you do not require A/C

if you are looking for energy efficient systems then there are some solar fan driven systems around like the sun lizard.

you could also look into solar chimneys. a contemporary version of a solar chimney is a painted black box on the roof with a duct into the room below. as the box heats up the air inside heats up and escapes drawing the air in the room space along with it. just depends how hi the ambient temperature is.

other systems available are geothermal heat exchange systems etc.
www.geothermodynamics.com.au/

and the list goes on and on.

I have installed several passive solar cooling systems on my house (thermal chimney, ceiling vents, solar and wind powered heat extraction fans) In short, they don't work.

They do stop heat build up so they prevent the hot box effect where your room is hotter than ambient temperature (like the inside of a car on a hot day).

They do help to take best advantage of any shade and insulation so your room will be several degrees cooler than ambient temperature. But on a 43 degree day your room temperature is still going to be over 30 degrees.

If you want cooling you need air conditioning.

I will watch Coolerado with interest. One thing that is sus about it is that I have not heard about it until reading on this particularly dodgey forum.

that's an awesome outcome,

several degrees is a large amount.

you could probably get higher if you had your natural breezes flowing over water like ponds or pools etc. in hot dry areas that's the best setup.


ie. a very large coolerado

We had a local (sea)breeze last week, outside temp was still 36c at 5.30pm, I definitey enjoyed the air-con

My house is designed so we get the sometimes, cooler seabreeze blowing straight through the 2 sets of double doors upstairs, when the temp gets up above 35 for a few days the air-con is the only way to go.
I think its time for the arrival of a few solar panels to compensate for my greedy use of electricity

i guess that's always going to be the case cassa.

i just deal with it myself as it only temds to be about 5 days a year and i just go to the beach.
