A portable air conditioner works in much the same way as a conventional unit. However of course with these units they have been placed on casters so that they can be wheeled from one area to another. Most of the units will come with a hose attached to the rear which you need to place in a door or a window so that the hot air the unit extracts from the room can be expelled outside.Just as with a conventional air conditioning unit the portable ones will also remove any moisture (water) from the air. But instead of this actually being expelled you will find that the unit will store it in order to help cool the unit down further. However these machines are also fitted with a bucket or tray into which water is deposited and unfortunately you will need to remove this and then empty the contents in it on a periodic basis.
So what is needed in order for you to run portable air conditioners? In order to run such equipment they need three things. The first is that there is sufficient space in which the unit can stand. Secondly you will need an electrical outlet from which the unit can gain power to operate. Finally an opening is required such as a door or window which the hot air can then be expelled from the room.
