Portable A/C

[Abby Normal]

Any recommendations for a portable A/C, about 8000 BTU (the kind with a
flexible duct that goes into the window)?

I don't need heat from it -- just A/C and dehumidification.

The names Soleus and Amcor pop up a lot. The familiar names like Friedrick
don't seem to have anything at all.

Get one with two hoses, the single hose ones cause a fair bit of
outside air to infiltrate in

As is your bad advice here.

Ahh I see I have a fan thats awesome makes for great debates that
invaribly I win.

Locally a portable unit is 450 bucks

thats kinda pricey

You can buy 3 5000 BTU windows units and have bucks left over.

plus no messing with condensate drain, noise mostly outside, walk from
room to room in comfort.

plus often its useful to cool say a bedroom before bedtime.

with a portable it will already be in use.

so please explain why my advice is bad. sure portables have their
place but its not a mainstream product, since its cost is high

My 2 cents on a portable AC:

1) Get a model with two hoses - the two hose models use outside air to
cool the condenser and will be more effecient. You will not be
sucking the cooled air out of the room to blow it outside - this is
what the models with one hose do (the condenser air comes from
somewhere.
2) Be prepared to have a real drain (ie hose going somewhere) on the
unit unless you want to be emptying condensate all the time. They
seem to be able to blow some condensate out the air hose, but unless
you are in a dry area you will probably get more condensate than what
it can evaporate out the air hose. (If you want to pump water out the
window you will probably need a condensate pump and some
3) They are for the most part pretty quiet. It seems most of the
noise is what you can hear through the thin walls of the air hoses
leading to the window (these hoses connect to the area the condenser
fan and compressor live in - most of the noise is in there).

I personally have had a PAD-121 running every night for 3 years
without any issues. That model is no longer available, but the
successor is: http://www.heatcontroller.com/series.php?prod=ca&sid=15&c=17

Wish I had known about the two hose units!
Now that I think back, I seem to recall two hose units, but didn't realize
the purpose.
Unfortunately, never saw any two-hose units when I was ready to buy, and
likely the PC Richards people wouldna known what they were for, either.

Good link, but website wasn't that informative--no price, EER. Any ideas?
Other observations good as well. Prodigious condensate. I "prefer" to empty
buckets/use the water, but it is a chore.
A pump to a storage barrel would be better.
The 850 watt Amana can readily fill a 5 gal pail in 24 hrs.

They're all pretty much the same, there's virtually no difference at all
between the small rotary compressors they use, and they're all about the
same efficiency (not very) due to mandated standards. Buy one that has the
features and cosmetic design you like.

 

[James Sweet]

For winter, get a standalone dehumidifer--which also acts as a 600-800
watt
heater.

The OP said he didn't require heating. I think you're a bit on the
high side in your heat output estimate. I think 400 watts for a
residential unit would be more realistic. You're dropping the
relative humidity which will affect latent heat, and the units
themselves only draw 600-800 watts. Even a heating element isn't 100%
efficient.

Dehumidifiers don't use heating elements, they just pass the chilled
dehumidified air through the condenser which heats it back up. There's some
net gain, since the power consumed by the compressor (about 400W) becomes
heat.

What would be realistic is :

The total power consumption of the unit
plus
The latent heat of condensation of any water it takes out.

100 % of the above will be sensible heat in the space.

Even a heating element isn't 100%
efficient.

*If* installed properly!

Not another one...

Since when is electric heat not 100% efficient?

What are you using the water for?

 

[Richard J Kinch]

2) Be prepared to have a real drain (ie hose going somewhere) on the
unit unless you want to be emptying condensate all the time.

Or you can add a condensate pump for about $40.

 

[Richard J Kinch]

So you're saying a dehumidifier that consumes 800 watts of energy is

providing more than 800 watts of heat?

Yep. Think of it as a swamp cooler in reverse. An unswamp heater.

Psychrometrics are not so favorable, however. It's a dry heat.

*If* installed properly!

I prefer to haul it out in 5 gal buckets--water ther tomatoes and whatnot.

From elsewhere, I know he's also a machinist--and so probly he uses it ( as
do I ) to mix with water soluble cutting oil or synthetic instead of buying
DI water...just need to add an anti-microbial..

Well, it will produce more than 800 watts worth of
heat. Where did the extra come from, the
condensing of the water from the air. When water
vapor is condensed to liquid, it gives up heat.

Where was the heat in the first place?

In the room... so it's not EXTRA heat!

Fucking idiot, as usual.

Don't dispose of the water, and don't take in any additional moisture and
then what exactly do we have here now?
