95% summer.

Well I guess you are just easily pleased for 95% of summer.

Let's put this thread to rest...can we all agree that...

Advantages of evaps. ACs...........................
Cheap to buy
Cheap to run
Useful most of the time in dry climates like Adelaide


Disadvantages of evap. ACs...................................
Marginal cooling effect, only 10degC or so under optimum conditions.
They increase humidity - which can make it more uncomfortable.
Useless most of the time for much of Australia, Sydney, Brisbane, Darwin etc.
Useless anywhere when ambient humidity is high.
Require a water supply

Advantages of refrigeration/heat pump ACs...........................
Maximum cooling effect - 20degC or more is easily achieved.
They decrease humidity - which makes it more comfortable.
They always cool effectively and always decrease humidity.
Usefull all of the time anywhere in OZ.
Reverse cycle units can heat efficiently in winter

Disadvantages of refrigeration/heat pump ACs...................................
Higher initial cost.
Higher running costs - compressor, twin fans.
Require water drainage.

No, but air south of Adelalaide comes from cooler regions until global
warming really destroys the Antarctic!
Maybe you need to consult a map to get some idea?

Incidentally, when a cool change hits a location and it rains, the moisture

comes from the warm air at the location and not the cool air arriving. The
warm moist air is forced to rise quickly where it condenses and rain is
formed. If the warm air is too dry then it won't rain. Sort of shot yourself
in the foot over that one. By definition, if it rains then it must have been
humid.

Now tell me that is wrong, no doubt you will.

Yours and othe greenie comments confirm my suspicions that this thread is
based on pro green propaganda more than common sense as I said before.

On another note....Refrigerated air works %100 of the time. Not just when
the weather is right.
It also works well in any location not just hot dry places
It especially works well on humid days and that is when aircon is most
desireable
It takes moisture out of the air and not put it back in. It can also be an
efficient heater outputting around double the heat energy in Joules that it
uses in electrical energy input joules
It has never been more affordable and is quite reasonable to install with
flexible ducts etc. Split systems are very cheap.

Oh, BTW I take it as read that you will disagree with everthing I have said
above so there is no need to reply, tho no doubt you will.
I have no interest in continuing corresponding with internet lowlifes who
never contribute anything positive, have limited knowledge on the subject
and just vent their aggression in the manner that you do.
I will however be glad to correct your lack of knowledge when it is
displayed in future here or anywhere else.
Maybe you can stir up that frequent poster who you enjoy fighting with to
help you with the chip on your shoulder

You are a sarcastic twat. Seems you cant stand the fact that evap
coolers work well. I'd say you have never lived with one, you just
quote theoretical generic and erroneous shit about weather, listen to
the other posters who speak from experience and don't want to big
electricity bills.

Poor little geoffie is upset.
Never mind , save your pennies, work hard and you never know you might be
able to save up and buy a proper aircon.
Maybe you are getting a little hot under the collar. Better go and cool
down..... find a refrigerated aircon
When did they get electricity down there anyway?

Hey Geoffie,

Have to tell you this.

The greenies invented a new plane.
Unfortunately it crashed 95% of the way through its maiden flight.
It seems the designers reckoned as long as it worked for 95% of the time
then that was fine.

Couldn't be bothered, the concept of warm moist air Vs HOT dry air seems to
escape you for a start. And the concept of rapid air changes caused by
strong wind also seems to be lost on you. We DO have long periods of hot dry
air followed by rain in the southern states. But feel free to believe
whatever you like, as long as you don't have to prove it. I sure don't give
a rats how ignorant you choose to be.

Yours and othe greenie comments confirm my suspicions that this thread is

You have proven you have none at least. Nor any consideration of anyone
besides yourself.

It has never been more affordable and is quite reasonable to install with
flexible ducts etc. Split systems are very cheap.

To buy, yes compared to only a few years ago. And some people can even
afford to run them at the moment.

Oh, BTW I take it as read that you will disagree with everthing I have
said

Of course you agree with everything I have said then?

I have no interest in continuing corresponding with internet lowlifes who

Are you looking in the mirror? I couldn't have put YOUR "contribution"

I will however be glad to correct your lack of knowledge when it is

But you still haven't proven ANYTHING I have said that is actually wrong.
Better luck with your next tilt at windmills.

Hi Tony,

And I suspect the pads lose efficiency over the years and I am thinking of
replacing mine. Or has anyone ever managed to "revive" them? They clog up with
calcium and dirt over time and I wondered if the same treatment you give pool
filters would work with them? (acid bath)

I'm told they need to be hosed off at the close of every season to get
rid of evaporated salts, mud etc.

However, after a few years (probably >5-8 years) they do need to be
replaced since a/c effectiveness drops off. They did initially claim
the celltek pads practically lasted forever, but that proved to be
optimistic.

If you are handy it is an easy job to do yourself. I haven't yet
priced replacement pads, but I'm told the celltek pads are not that
inexpensive.

They do work surprisingly well if the conditions are right. Yet I can't get
myself putting up with a relative humidity higher than 60%

I wondered about that myself. At 22C here in Adelaide it is often 50%
humidity. And early this morning it was 14C and 65% humidity.

I'm unable to tell the difference between 22C at 50% humidity, or 22C
at 70% humidity. I thought I would easily know the difference but I
don't.

Without the a/c if the house got to 25C I felt like turning on a fan.
It was surprisingly consistent for me to do this.

I'm often seriously engrossed on my computer, and I was surprised to
find that dead on 25C with the evaporative a/c running I felt like
running a fan again.

Intuitively I'd have thought that the need to turn on a fan would
occur lower than 25C because of the higher humidity. But it didn'r. I
was a bit surprised at that.

Btw the Steadman Chart says 22C air at 50% humidity has an apparent
temperature of 22C, while 22C air at 70% humidity has an apparent
temperature of 24C. So my intuitive feeling is backed by scientific
fact.

However, for me I could tell no difference between 50% and 70%
humidity at 22C, despite the Steadman figures saying I should be able
to.

HI, take it from me , swampys ( evaps) are useless in humid weather.
evaps are better, i hate these tosser that have it set at the government 24
c or whatever it is.
that is just plain retard.
they dont take into account the ammount of people in a building, and also
what they are doing.they have it cycling the compressor in and out.

they have it set for a high temp on a hot day, cooling down its ok , but as
soon as the compressor couts out , it starts warming up staright away.,
especially on a very hot day, you have it set to abvout 18 c,.

(snip)

The a/c cost about $4/day (cost of water plus electricity) to operate
- a very low cost to cool the whole house plus the garage. An
equivalent refrigerated unit might have cost up to $300/week to run.

I checked how my former work place was going about 10 days into the 15
day heatwave. With my house thermometer showing 25C the temperature in
this workplace "no-expense-spared refrigerative installation" was 24C.


$300 per week to run a domestic installation???

That means 300/168= $1.80 an hour if it was running continuously.

In Sydney I pay 14.4 cents/kw hour for top rate electricity
which means the unit would have to use 12.5 kilowatts.
That is a mighty big ac for domestic use.

By comparison I have a 19hp unit and a ducted system which uses 6 kw.

Isn't 19hp more like 14kW?


I am not sure how the air conditioning people calculate the rating of 19
hp.
I think it is something to do with the heat output, taking into account
the efficiency of a heat pump. The energy used by the air conditioner is a
different thing and does not contribute to the heat "pumped"
The electrical requirement to run the compressor is quite a bit less than
the rated heat output.

The figures I quoted are taken direct from the manufacturer. 19 hp unit
which uses 6kw.
6kw is also on the plate fixed to the machine.
