A quick guide to air conditioning
Unlike fans that simply move the air around, air conditioners actually reduce the temperature. The hot air is drawn into the unit over an evaporator, which contains a low pressure and very cold refrigerant. The cool air is then blown out through the front vents while the hot air is expelled through a rear hose.

Mobile units like this one can be simply plugged into the mains socket. You need to make sure the hot air is extracted, along the hose, through a small hole in the wall. In the short term, however, you can direct the hose through the window or door.
