Seems to work on the same principle as hanging a damp towel over a fan.
Lots of pages on the web (google "aircool review") - but most of the
reviews are the manufacturer's blurb regurgitated.

I guess it will give the effect of cooling, as it's blowing damp air
over you....

As you say, if it seems too good to be true....

Evaporative cooler, they do work but only work well in dry air. We
used to have them in our house in Riyadh (Saudi Arabia) back in the
1970s. Riyadh was much smaller then and the humidity was low, the
'desert coolers' worked well and made for very pleasant feel to the
rooms indoors. They were much quieter than Air Conditioning and, of
course, cost *much* less to run.

It appears to be an evaporative cooling system. It is a principle that
has been with us since the days of ancient Egypt.

They work best in hot, arid climates, with the effectiveness decreasing
at lower temperatures or higher humidities. They also output moist air,
which is not always desirable.

It's a swamp cooler, it's not air conditioning. They work in dry climates,
where evaporating water takes heat out of the air. They're good in arid
deserts, less good in the UK where the air can be muggy (and this will make
it more muggy).

There doesn't appear to be anything special about this one compared to
fan-and-grass-mat swamp coolers the world over.

It doesn't actually claim "the same cooling capacity". That'd be an
objective statement. It claims the other coolers "perform worse" which
is subjective.

Well the web page it impressively full of marketing wank for what is
usually known as a "swamp cooler". There is nothing new or revolutionary
about these.

They are basically evaporative coolers that rely on the blowing air over
something damp, that then causes the water to evaporate, and it takes
the heat required from the airflow. Outputting cooler wetter air.

Unlike air conditioning they don't actually extract heat from the room,
and they don't de-humidify. So for the UK climate (or anywhere else
where high temperatures are usually accompanied by high humidity), they
are worse than useless. The high humidity will prevent them from
achieving much evaporation and hence cooling in the first place, and
they will increase the humidity in the room making it even more
uncomfortable.

Now in some climates where its very hot and very dry, they work very
well - since the extra humidity they generate is actually welcome, and
the temperature drop they can achieve is also more significant.


Here is a a pretty decent explanation:

Where does it claim that? There is a vague comparison but not a
claim.

"The majority of air conditioners on the market are 10x heavier and
up to 8x more expensive and, shockingly, they perform worse."

Presumably, it doesn't, I'm guessing all it does is cool a tiny fraction

Yep. "With CoolAir you get your own personal bubble of comfort."

The fact it'll run from a USB port ought to tell you something. It
simply hasn't got the power to do very much.

It's an evaporative air cooler, blow air over some thing wet, the
water evaporates which requires energy which is obtained from the
passing air, thus cooling that air. It does appear to have quite a
large surface area for the evaporation which is how it might be able
to achieve that 14 C below ambient temperature reduction. How well it
performs will be very dependant on the humidity, 36 C and high
humidity it's going to do SFA, 36 C and 10% humidity it will do a lot
better.

Proper air conditioning removes the heat from the air but then dumps
it somewhere else (outside normally). An evaporative air cooler
doesn't dump the heat some where else, it just hides it temporally in
the water vapour. This heat is given back when the water condenses.

Indeed, evaporation is a cooling action. In the hottest of deserts,
the sun on a porous clay pot can drive the water to extreme low temps.
Knurling the surface creates more faces and greater exposure.

When its very warm weather, I will dampen a towel and place it around my
shoulders or, when in bed, over the body. It's very effective. Which
leads to survival and NOT wearing wet clothes when exposed to the cold
and near a localised heat source.

Do you *need* a portable unit? A wall-mounted split unit is more efficient
as it doesn't suck any air in from the room, it simply runs through a
chilled heat exchanger. Portable units often use room air to exhaust the
heat, which causes a negative pressure in the room and sucks in more warm
air through any leaks it can find. You can get dual-pipe portable units but
they're less common.

No idea who the OEM for 'Electriq' is (being a rebrand of random Chinese
stuff), but experience of maintaining A/C in very hot climates (50C+)
indicates to go for a major Japanese/Korean/American vendor. The Chinese
stuff just dies. eg https://www.cooleasy.co.uk/categories/wall-mounted

however it might be tricky to get someone to gas it up, in which case:

It's a pc fan & a bowl with some cloth. If you have a fan you can try the experiment yourself. If you cba, yes you get a little cooling right in front of it, not much. £60 is laughable, £6 would be a bit steep.

On speed two of three I can still sleep easily (noise levels).

If we go somewhere that doesn't have a ceiling fan the air seems so

Is this one of the ones you fill with water? The better ones also have a
dehumidifier. They work well in dry heat, while making the air more humid
usually.
Then there are the ones with the pipe through an open window, say no more.

Yes, also of course the main reason we tend to suffer in this country is the
high humidity we get with the heat, hardly surprising as the UK is
surrounded with water of course, but when you sweat you expect the
evaporation of the moisture to cool you, but it won't because the air is
almost saturated already. The only answer is to alter the pressure or move
the air over you to use as much of the little bit left of room for moisture
onto your skin. Likewise these devices try to so the same with a wet filter
of some kind, As I have noted before, there are some larger units, often
seen abroad that also seem to have a dehumidifier of some kind. I'm not
saying they are better, but subjectively they are, but you end up with a
tank of warm water at the bottom, and a bigger leccy bill. ahem. The most
efficient way is the closed loop system with a material that can be
evaporated at different temperature, ie an air conditioning unit, basically
a large version of a fridge heat pump, where the excess heat is outside not
in the room with you.

If the dust is air bourne and drawn into the unit most likely. It'll

might give it a try there are some very cheap ones on ebait .....

How can it possibly have (as is claimed) the same cooling capacity as

it can't, unless they've found someone selling an equally ineffective
miniature ac unit for silly money.


Presumably, it doesn't, I'm guessing all it does is cool a tiny fraction
of
the volume of the more expensive ones?

any comments?

It's a pc fan & a bowl with some cloth. If you have a fan you can try the
experiment yourself. If you cba, yes you get a little cooling right in front
of it, not much. £60 is laughable, £6 would be a bit steep.

Yes, also of course the main reason we tend to suffer in this country is the
high humidity we get with the heat, hardly surprising as the UK is
surrounded with water of course, but when you sweat you expect the
evaporation of the moisture to cool you, but it won't because the air is
almost saturated already.

That's a much heard argument. The reality is they do feel cooler than just a fan, but not by much.

Do you *need* a portable unit?

I *need* one that doesn't require a hole drilled though the property
owner's wall (who isn't me)

FSVO needing one at all, that is

I'm, aware that it won't be as good, but what choice do I have?

Other than suffer 32 degrees for however many days it's going to be
(predicted to get worse in future years)


Fairly easy with a sash windows get a board a good bit wider than pipe;
cut its length to the width of the window openinh; cut hole of the pipe
- no need for accuracy when duct tape exists; insert board at bottom and
close sash on it.

Other windows I'll leave to the clever'uns

It appears to be an evaporative cooling system. It is a principle that
has been with us since the days of ancient Egypt.

They work best in hot, arid climates, with the effectiveness decreasing
at lower temperatures or higher humidities. They also output moist air,
which is not always desirable.

However in "hot, arid climates" moist air is very desirable! :-)


And you don't end up with toxic mould in your static van, as happens
in southern USA

make your own. Just attach some kitchen towels to the front of a fan
and keep squirting water on them with a garden spray.

OK

so back to one of these then:

Forgive me if I'm stating the obvious but they really, really, do need
to vented outside if you want to cool a room. I knew someone who missed
that minor little detail before parting with his money.


Even more people think that opening a window (especially south facing)
to drape the hose out of is all it needs. The hot air comes straight
back in ....

I spent £4 on a lifesystems survival thermal blanket (90's) and have
recently 'found' it and stuck it to the inside of my south-
facing aluminium DG patio doors with some of that blue
maskingtape. Also a couple of large offcuts of 60mm 'celotex'
which means the downstairs has not gone above 27C so far.

Noticibly cool when I come into the house.

An external frame made out of trellis to use it to shade the outside
would be even better. Next year I am going to get one of those
Australian devices that looks like a sail and fix it to the
rear wall with two big expanding bolts and use a couple of
tent poles to hold it up away from the wall.

You still can't beat a good cup of tea with semi-skimmed and
sit in front of a fan.

the air over you to use as much of the little bit left of room for moisture
onto your skin. Likewise these devices try to so the same with a wet filter
of some kind, As I have noted before, there are some larger units, often
seen abroad that also seem to have a dehumidifier of some kind. I'm not
saying they are better, but subjectively they are, but you end up with a
tank of warm water at the bottom, and a bigger leccy bill. ahem. The most
efficient way is the closed loop system with a material that can be
evaporated at different temperature, ie an air conditioning unit, basically
a large version of a fridge heat pump, where the excess heat is outside not
in the room with you.
