Movincool air conditioner ?

Has anyone tried using a Movincool air conditioner in their shop? I'm thinking about getting something like this:

It is similar to a home portable air conditioners but runs on 240V and is quite a bit larger. I would imagine the air coming directly out of the ducts is cold, but does the cold air spread around the room? Or does the overall room get hotter, with just a very localized area getting colder?

Any comments from those who have used one?

The site says: " ** Exhaust duct required in most cases." So the heat goes wherever you exhaust it to, typically out a window or a dryer vent. Note that there are many amall packaged 110V. units on the market these days, they are used where it is not convenient to have an air conditioner hanging out a window. Usually cost $500.00 to $800.00 and are typically 10,000 BTU or less.

The room will get hotter if you don't use the exhaust dust duct.

The cost of this thing is $3500and for only 18000 btu is no better than a mid size room window unit. You could buy a 18000 btu window ac and have the same results for around $400. My shop is about 2000 sq ft. I bought a 42000btu (3.5 ton) out door condenser and a cooling coil and a blower I didn't even run any duct work and the shop gets very cold. If I had to do it again i would buy a mobile home split system You can buy it yourself and save alot the unit is precharged with freon and easy to install .

I'd guess that the two ducts shown on the machine at their web site are for outside air in and heated air back out. Not possible to "make cold" out of nothing. You extract the heat and put it somewhere where you don't mind it being. (outside, into waste water, whatever) but you get the idea.

I have used a home one in a home. I think it's about 1.25HP. It is almost useless in a 12*15 room. whereas a wall-mounted one would make quite a difference, even though barely adequate. They are probably about 1/3 as effective as a wall-mounted one of the same power. Maybe

1/2. The salesman actually tried to stop us buying one, but we were in a temp situation and did not want to install.

The problems are: - the exhaust tube. Cooling air needs a lot of air movement, and the tube restricts that. The tube also gets damned hot. We were forever mucking about placinf blankets around the tube to insulate it - Also, of course, all of the unit's own heat generation is inside the room/shop, not elsewhere on the wall. Although a lot of that is taken out the pipe, it all adds up.

It works just like a window unit - warm room air goes in the front and cool air out the two top holes, where the flexy hoses direct it. Where it's different is it takes in room air for the condenser coils too, and pumps the hot air out another hole in the back. The condensate that they can't evaporate off in the hot air exhaust goes into the tank at the bottom. (Unless you rig a drain hose, that will have to be dealt with daily.)

Normally you pipe the hot air exhaust from the back out a window or roof vent of some sort, and they provide a hose and a window fitting to do it with - if you don't send the heat outside somehow you're just moving it around the room, and adding the compressor load to it... Or you put the whole unit outside and pump the cold air into a small cooled space or room.

These portables are good for specialized uses, where portability is paramount (movie sets, jobsites that change weekly, rented spaces where if you bolt something down it's now the landlord's) or you can't use a window unit (no windows) or central air.

Those "Movin' Cool" units are very expensive for what you get - if you can use a window unit or build in a wall sleeve for a larger Packaged Terminal AC or Heat Pump, that will be cheaper in the long run....

Even a "Mini-Split" ductless like Hitachi and Mitsubishi make

would be a better deal - that's the same idea as a Central Air, the refrigerant lineset can go through a 2" hole in the wall. Perfect for brick and block structures, you just core drill one hole.

And evaporative "swamp" coolers are an excellent alternative to refrigerated AC (and dirt cheap to run) that are good for large garage, workshop or warehouse spaces located in dry climates where the higher indoor humidity doesn't cause problems.

Not a good idea. It will blow some cold are right on you but it is dumping the hot air in the shop unless you duct it out. For the same money you can get a split system installed that will do a much better job.

Can you poke a hole in the wall and install a window unit? That would be the most economical. Ed

Before everyone thinks this is for a shop attached to the house - think of the

3 or 4 story long buildings with metal or stone working away inside. These are set up for work stations. The hot air gets vented UP. Cold Down. The monster fans help a lot - but not in work stations here and there.

We've used similar units at work on a temporary basis. On those units the flex tubes were the intake and exhaust for the condenser (the hot part) and were ducted to the outside. The cool air came out the grating on the front of the unit. The tank on the bottom collects the condensation.

We used some units like that in the computer room when the main A/C crapped out(frequent) at the navy yard. You had to open the outside doors to vent the hot air from them and they really didn't do a lot. Cold air only immediately in front of the units and we used fans to spread it around, but we frequently had to take the mainframe down because of the heat buildup. About all it did was allow jobs to complete before having to take stuff down. A/C maintenance was contracted out and it frequently took several hours for the guys to show up and fix whatever it was, then sometimes an hour or better to get the temperature down to where we could start the box again. The portables really weren't worth the bucks that were spent on them. Fans in the open doors did about as much good.
