I'm thinking of getting one of these for my office, but have a question about
how it disposes of the water. Does it work like a dehumidifier where you have
to empty a bucket every now and then, or does it somehow exhaust it via the
hot air exhaust out a window ?
the kind we had at work in some of the offices as a backup when the very
large cent units went out.. you had a 5 gallon jug that you had to
remove and pour down a drain to get rid of the water... no problem, it
was alot better then suffering in an office building that had no windows
to open and the parts were on order for the large central unit...i would
rather lift the water than to have to wipe it off my forehead........
I got a portable floor unit because my upstairs window a/c that came with
a home built 1910, glued into an framed opening in top half of window
(silicone sealer and expanded foam), suddenly failed when the heat came,
and my other windows have steel storm window/screens that may not be easy
The floor unit is a Maytag 8000 btu (basically a Fedders with full 5 yr
warranty instead of 1/5 limited). As is commonly done with window units
too, I think the condensate is slung at the condenser to help cool it with
evaporation, and is expelled in the form of water vapor out the vent hose.
If too much water accumulates, it will automatically shut down until
drained. I have only had it for a few days (including temps in mid-90s),
but so far it does the job and has not required draining.
It does cost twice as much as a window unit, but it is more easily
installed without help, can be installed where a window unit cannot, and
can easily be moved to a different room or location.
And when I get around to replacing the upstairs window unit, I can use it
on its dehumidify setting to dry (and cool) my half exposed basement,
which starts getting warm in midsummer.
Would a reg de-humdifier actually cool a room pretty
well in the fact that it would be removing the moisture
form the air?
I mean... with a portable AC you have two units ... one
that sets inside and one that must set outside to pump
the heat out, right?
Whereas with a de-humdifier its one unit only as all
its doing is removing humidity from the air. So.... by
that very fact Im wondering if just removing the
humidity could make a room feel cooler?
The heat from condensor and re-evaporated condensate of a portable unit is
exhausted through a 4" vent hose (like a dryer vent) to outside through a
small window mounted panel. This draws in some outside air somewhere, so
you are not breathing the same stale air all day long.
A dehumidifier is like an air conditioner, but the air that is cooled by
the evaporator to remove the moisture is then reheated passing through the
condenser (instead of being vented outside). So the air ends up drier,
but slightly warmer.
That is a mini split, which is efficient because it just has small tubes
between inside and outside units and no duct losses, but it is not
portable and not generally DIY.
A dehumidifier can make it feel somewhat cooler since the drier air has
more moisture holding capability (effective evaporative cooling of your
skin instead of soaking sweat), especially if your a/c is oversize and
does not remove enough humidity due to short cycling. But they are most
commonly used to stop cold pipes from sweating in a cool damp basement
since cold air cannot hold as much moisture.

I know my dehumidifier warms up my finished basement considerably. On a very
humid 80F outside day, it can be 70-72F in the basement and clammy. The
dehumidifier works great to remove the moisture and clammy feel, but in a
matter of 3-4 hours the room is over 80F. I'm using a 50pint/day unit in a
