Floor-ceiling split systems differ from wall-mounted ones only in the structure of the indoor unit. The latter has a slightly different type of housing and can be installed on the floor or under the ceiling of the room. The control panels of such devices are located on the indoor units or remote controls.
The heating and cooling capacity of floor-to-ceiling models is usually from 3 to 12 kW.
Column split systems are powerful large-sized machines that have a column-like design of indoor units. They are located on the floor in large rooms where it is necessary to provide fast and efficient air cooling: in restaurants, hotels, conference rooms, etc.
The operation of column models can be controlled using remote controls or special built-in panels.
Cassette-type split systems are designed to work in medium or large rooms with false ceilings, behind which indoor units are installed. These cassette models resemble wall models. Their main difference lies in the fact that the design of the internal units provides for uniform cooling/heating in four directions at once. The airflow paths are set by the blinds, which are set at a certain angle of inclination with the help of a remote control.
Indoor units of channel-type split systems are mounted and thus hidden from view behind suspended ceilings. In the same inter-ceiling space, there is also a system of heat-insulated air ducts that distribute cooled air in the room. Thanks to this design, ducted air conditioners can create the effect of coolness in several rooms at the same time, and, if necessary, even supply fresh air from the street.
To save useful cubic meters in apartments, indoor units of ducted air conditioners are mounted where the presence of a high ceiling does not play an important role, such as in toilets or corridors. Here, suspended ceilings will “absorb” from 25 to 40 cm. But in all other rooms, they will drop by no more than 10-15 cm – this is enough to hide the air ducts. If you install air grilles above the doors located between rooms and corridors, you can do without suspended ceilings altogether.
True, the installation of duct air conditioners requires the implementation of design work and an accurate calculation of the cross sections of the air ducts. This is because the desired temperature can only be set in the room where the indoor unit is located, and in all others, it is regulated in a mediocre way. If the diameters of the air ducts are chosen incorrectly, then it is quite difficult to control the microclimate in all rooms. Modern automated control systems can come to the rescue, which, although they cost a lot, ensure the accuracy of setting the desired temperature in many areas of the house.
Several internal units (from 2 to 5 units) can be connected to each external block of multisplit systems. The latter are of various types and capacities. This is the main difference between such air conditioners and traditional ones. The use of multi-split systems allows you to save space on the facades of buildings and not spoil their appearance with a large number of unnecessary elements. The main disadvantages of these air conditioning systems are the high cost and laborious installation associated with the need to separate a large number of communications.
An interesting option is the “constructor” type system, in which an arbitrary combination of indoor units, selected following the dimensions of all rooms of the housing, can be connected to one outdoor unit. Such models will significantly save on electricity, provided that most of the individual rooms in the building are of small volumes. After all, a kilowatt of air conditioner power is enough to cool 10 sq.m of area. With multi-split systems, installing a model of just such a performance is not a problem, while the minimum power of mono-splits is 1.8-2.2 kW, which is too much.
That’s what air conditioners are. We are convinced that now you will certainly choose the ideal model for your home or office and will no longer suffer from the heat.
