Split air conditioners are divided into: wall air conditioners, ceiling-floor air conditioners, cassette air conditioners and duct air conditioners. Split air conditioners consist of two elements, ie an indoor unit and an outdoor unit.

Another group of popular claylizers are ceiling / floor splits. As the name suggests, they are designed for installation under the ceiling, as well as near the floor - under the window. Where to mount the air conditioner? By placing the air conditioner in a vertical position under the window sill, we block the inflow of hot air from the outside. In turn, turning the air conditioner to the level we get a floor-mounted air conditioner. Such assembly is difficult but it is worth to overcome this difficulty, because the air conditioner mixes the air cooled with hot very well, and thanks to that we will not complain about cold breezes. In rooms with a suspended ceiling, there is an option to install a duct air conditioner or cassette air conditioner. An unquestionable advantage of cassette air conditioners is a great freedom regarding the planning of usable space, because they do not occupy space on the wall or floor. Such air conditioners are used in higher rooms. The distribution of air melts in 1, 2, 3 or 4 directions. The best models of air conditioners are those in which the air flows in 4 directions. In this case, the cold and warm air mix evenly and when it reaches us, it has an appropriate, even temperature. For those who feel the aesthetics of the interior design, the duct air-conditioners . Duct air conditioners are built into the ceiling, thanks to which only the grids with which the air flows into the interior, and not the entire device can be seen in the room.
