Air conditionng

I have a 17 foot (opened) pop-up coleman camper. I need some type of
portable air conditioning unit. I have heard about a couple of brands.
Can any one turn me in the right direction? The dealer wants my first
born child to install it himself. LOL.

I found an interesting alternative to the standard ac. There might be
many arguments against it, but on the surface it sounds like it has
potential to me. It is about half the price of air-conditioners that I've
seen..and none of them were portable. The item is called "Swampy". It is
portable. This is the address: www.swampy.net
Hope this helps.

I have no direct experience myself with the many brands of so-called
"swamp coolers", but I've seen it written (and people have told me) that
1. They cool by evaporating water.
2. They use significantly less electricity then normal A/C.
3. They work quite well when and where the humidity is very low --
such as in most parts of Arizona much of the year.
4. They are useless when the humidity is high.

The kicker is item #4 on the list. _Where_ and when will you use the
cooler? Will you ever need/want it to work well in high humidity?

In July '98, I chatted with a guy who was full-timing in a relatively
small trailer towed by his truck. He had _both_ conventional A/C _and_
a swamp cooler. He used the swamp cooler when he happend to be
somewhere hot and dry, and the A/C when it was hot and _NOT_ dry.

Your post is a bit confusing. You say you are looking for a portable
unit, then you mention the dealer 'installing' it. It can't be both. Do
you mean an RV type air conditioner which is a permanent installation?
If so, I recommend you slide over to alt.rv.pop-up-trailers where there
is a lot of discussion about the effectiveness of these and what size
works best where. The use of air conditioners in the large, uninsulated
interior of a pop-up is quite different from in a hard-side, and that ng
is where the experts in this arena hang out.

All good points- and I will add another one. Normal A/C will
drop the temperature of the air about 20 degrees (rule of thumb)- what
makes it work well is that it can recirculate the cooled air- i.e.-
the air starts at 100 degrees- come out at 80, mixes with some hot
air- goes back in at 90, comes out at 70.... you get the idea.

With a swamp cooler- you will get a 20 degree drop also
(provided the humidity is low)- however, once you have had that drop-
the air is humid, and trying to recirculate it will not work.
So swamp coolers work very well in dry conditions- where you
pull in hot outside air, cool it, and then exhaust it.

Anyone know if it is possible to set one or both of the Duo-Therm by
Dometic 620315 Penguin Air Conditioner "Pods" on the roof of my 1997
Newmar Mountain aire to only recirculate the inside air and not pull
in outside air.

Just got it back from Camping World (toad brake) today and the service
manager never heard of the possibility.

I'll call Newmar next week. But I'd even consider replacing one of the
units if it would be possible with most any brand.

inside air. The evaporator and condenser sides are separated and each has
its own heat exchanger. The part which is outside the coach is the
condenser and this is where the heat drawn from inside the coach is
dissapated. The cooling portion of the system is inside the coach and
recirculates the inside air through the evaporator heat exchanger.

The dashboard air conditioners generally have two modes of AC operation.
The mode called "Max AC" recirculates the inside air. The other mode,
sometimes labelled just "AC" draws in outside air.

Sam,
The Penguine A/C should not be pulling in outside air- it
should only recirculate- if it is pulling in outside air, it might be
that the outside cover for the coils is damaged- not hard to do, as it
is made of styrofoam on that unit.

The other possibility is that of the ducting itself (if it is
a ducted unit) being bad, or something being out of place (I know a
friend has a Newmar with ducted supply *and* return).

I'm going to hope that the sevice manager misunderstood you,
and thought you were asking how to draw in outside air, instead of
recirculating (or maybe I misunderstood).
