Too hot in the garage... ne suggestions?

[irishanaconda]

every portable I have ever seen needs to be vented somehow

yea thats sort of the problem because it does have a garage door but no windows, and i really dont want to smell up the neibhorhood. Is there any models without venting?

they need to exhaust the heat

basically they intake the heat on the one side and exhaust it on the other.

not if you get a swamp cooler it uses water to cool and recycle the air no exhaust needed

this is a small one but its the idea

The evaporative cooler, AKA swamp cooler cools through the evaporation of water. They work great here in Arizona by sucking in dry air from outside, running it through wet pads where the evaporation cools the air and then into the building. This pressurizes the interior slightly and it is exhausted passively through bathroom vents, stove vents, and poorly sealed windows and doors, or actively through an open window or specially constructed barometric dampers. They can also be used outdoors to blow cool air directly on you. If you put one in an enclosed, unventilated area it becomes a humidifier. You might have a cooling effect for about 30 minutes or so while it is steadily increasing the humidity of that environment, but the air inside will quickly reach a saturation point at which time the swamp cooler no longer cools and the building will begin warming up again to the ambient temperature imposed by the environment, except now with nearly 100% humidity. It is a nice, lower cost suggestion however it is not quite the right thing for this application. As for cooling the air with a portable refrigeration unit, I have seen them with dual ducts or a split single duct where they suck in outside air to cool the condenser coils then blow the very hot air back outside again. It is actually more efficient because in order for a unit to exhaust the air, it has to pull it from somewhere. And without a dedicated intake duct, you are pulling hot outside air into the space you are trying to cool. Just shop around for a portable that has that feature. BTW, window A/C units cool and recirculate the inside air, the condenser fan and coils are outside where they belong, and the better units can heat in the winter, too.

this would be how a vented one would work. if it doesnt have a vent (intake or exhaust) how would of pull in air from the outside and pressurize the room? the model type i posted a link to is pretty much a fan that cools the air.

That's kind of my point. The one in your link won't work for this application. There are some situations it will work for, but not Shane's. The humidifier "feature" described is what you'll end up with. Evaporative cooling works on the principal of... Evaporation! And in a sealed environment that evaporation will constantly ramp the humidity (That humidifier "feature" again!) until the air has so much humidity in it that no more evaporation occurs, hence no more cooling. It will cool for a little while, but once the air is saturated, it's done. If you expect to put in in the middle of a sealed room and keep it cool on a continuing basis, please make sure you buy it from somewhere with a good policy on returned merchandise.

things change I guess

Our old swamp coolers (in new Mexico) were fed water and had a relief valve. When the water reached a certain temp, the cooler dumped the water and a pressure regulator filled the cooler with new cool water. They looked like a huge car radiator with a huge fan behind it.
