If this question is still current. It does cool your room, yes.
This is called evaporative cooling.
It raises the humidity and cools the room. If you have very dry air inside you won't need to open your window either.
It works due to water having a high index of 'heat of vaporization'. It basically means that as the temperature rises water molecules become more and more likely to grab heat from their neighbors, and take off as a gas. So when your hot indoor air hits your wet clothes, it'll pick up some hot molecules of water and cool the wet fabric, (which in turn cools the air).
The hot molecules in the air cannot heat up your body or anything they come in contact with until they hit something cool enough to condense back into water.
When water condenses on a cool metal sheet, it does raise the temperature of the sheet of metal slightly, but the metal needs to be cool enough for the water to be able to condense to do that.
