In fact, this is a corrugated pipe of a mobile air conditioner. It serves to remove heat, which inevitably occurs during the operation of the device. The instructions for each mobile air conditioner say that hot air must be removed outside the room, otherwise the cooling efficiency is reduced.
The need to remove hot air is just one of the features of mobile air conditioners that you should be aware of even before buying. You can read more about this in our article. “Four Reasons Not to Buy a Mobile Air Conditioner”.
Why does the end of the pipe have to be put out the window?
The air conditioner usually comes with window plugs so that everything can be mounted neatly. However, they are designed not for hinged, but for sliding windows, which are often found abroad, but are not widely used here. Because of this, the problem arises of how to fix the end of the pipe in the window. The easiest way is to expose the end of the pipe to the window of an apartment or balcony, which is what some owners do.

Nevertheless, such a solution can only be considered as a temporary option, since it has several significant drawbacks. Firstly, warm air from the street will enter the room. Secondly, an open window is a source of noise, dust and flying insects. In addition, the open window must be additionally fixed so that it does not completely open from gusts of wind.
Partially the problem will be solved by a special sealant with AliExpress. It will close the gaps. And if you order several of these seals, you can freely move the air conditioner between rooms.
Stationary installation of a mobile air conditioner
The stationary installation of a mobile air conditioner involves the installation of an air outlet hose into a hole in a double-glazed window. However, the easiest way in this case is to close the window or window (if any) with plywood, plexiglass or other insulating material with a suitable hole.
Alternatively, you can still make a hole in the wall itself. However, this is not such an easy task and is more suitable for owners of private houses who, for some reason, do not want or cannot install a split system. For example, if it is a temporary house or a small country house on a personal plot.
