Traditionally, the indoor unit of a household split device is located on the wall. For most, this placement is the most acceptable and convenient. But it is not always possible to install climate control equipment this way due to certain design features buildings, premises. In this case, it is possible to buy a Daikin floor-ceiling air conditioner, for example, or Samsung, Hitachi, Fujitsu, Leberg, Ballu, as well as Midea air conditioners, etc.

Floor-ceiling air conditioner. Peculiarities

It is a split installation consisting of external and internal modules. The outdoor unit is the same as that of standard splits, includes a condenser, compressor, and fan. Mounted on the facade of the building.

The indoor unit is structurally no different from the wall-mounted versions: evaporator, fan, unit automatic control, filtration system, drainage tank. A special feature is the installation of a floor-ceiling air conditioner. Placed on the floor or ceiling depending on the characteristics of the room or building.

When the indoor module is placed on the floor, the cool air flows upward along the wall. Ceiling installation distributes air flow along the ceiling. Both options are comfortable for humans, since the air masses spread gradually, without a directed strong flow.

Are different high power(Chigo CUA-48HR1/COU-48HSR1 air conditioners for 14 kilowatts), since they were originally created as semi-industrial climate control equipment of larger sizes with high performance.

Scope of application

The design characteristics make it possible to place climate control devices indoors when wall models it is not possible to install. Installation of floor-ceiling climate control units is carried out:

• apartments, residential buildings, inside of which it is impossible to place an indoor unit on the wall;
• When wall mounting involves great complexity;
• the freon route is too long for wall installation;
• retail, public premises, restaurants with a large area of ​​glazed walls;
• office premises with shelving installed along the walls;
• rooms that do not have the ability to hide communications of wall-mounted, cassette split devices inside the walls, under the ceiling (models of Vertex ceiling air conditioners).

Air conditioning with inverter compressor

Leading manufacturers of climate control equipment produce split air conditioners that can economically consume electrical energy. Inverter air conditioner automatically reduces its power when the room air reaches the required temperature and continues to operate at reduced speed, maintaining the desired mode.

These include Panasonic ceiling air conditioners, LG floor-ceiling air conditioners, Aux 7 kW air conditioners, air conditioners Hitachi hitachi raf 50nh4, American Cooper Hunter air conditioners, etc.

An inverter air conditioner has a number of advantages, including:

• energy efficiency, economy;
• high performance power (air conditioning Aux 60 W);
• low operating noise level (up to 20 dB night mode);
• longer warranty period;
• compressor mechanisms wear out more slowly;
• precise adjustment of temperature parameters;
• route length (ceiling air conditioner Dantex RK-12 SEG, floor-ceiling air conditioners General Climate GC/GU-CF 24 HRN1 – up to 25 m, GC/GU-CF 48 HRN1 – up to 50 m).

Climate control equipment without housing

They produce climate control equipment that is similar in design characteristics to a split unit - a floor-to-ceiling air conditioner without a housing. The functions of the external unit are performed by the chiller. Coolant - water, antifreeze, connection to central heating possible.

Distinctive features:

• chiller and fan coil can be separated long distance without loss of quality of device operation;
• The cooling and heating circuit is formed from coolants, plastic water pipes. Accordingly, installation costs are reduced significantly;
• the standard variety allows you to install fan coil units in hidden niches of walls and ceilings. The width of the fan coil unit without housing is 20 cm. The type of device affects the method of its connection;
• the ability to operate for heating or cooling (two-pipe units), or combining heating and cooling (three-pipe units).

Often purchased for offices in big cities (Krasnodar).

Safety. Error codes

Floor-ceiling equipment is equipped with a safety device, which is responsible for correct use split When incorrect assignment of parameters, mode, etc. occurs. on the display of the indoor module, remote control remote control An error code is displayed.

There are different fault codes for each equipment. The transcript is contained in technical documentation to climate control equipment. Each error code indicates a different problem that needs to be corrected.

And from one manufacturer different types climate control equipment (split, duct, cassette, column) have different fault symbols, which must be checked against the explanation in the instructions.

Basic rules for installing an air conditioner

If a large room needs air conditioning, but there is no suspended ceiling – the right decision will install a ceiling air conditioner (or, as it is also called, subceiling). Ceiling air conditioning systems are powerful and practical, helping to solve air conditioning problems in non-standard rooms in which, for design and architectural reasons, it is not possible to install other systems.

For what purposes is a ceiling air conditioner suitable?

• Premises without a false or suspended ceiling.
• Premises with a large area (from 35 sq.m.)
• Rooms with glass walls, such as shops with display windows

Operating principle and design of ceiling air conditioners

Type – split system, consists of: an indoor unit (evaporation unit) and an external one.

Ceiling air conditioners are divided into two types of air flow distribution:
- Single-flow - air is distributed in one direction.
- Multi-flow – air distribution is carried out simultaneously in several directions, for example, under-ceiling Daikin air conditioners FUQ-B/RZQ-B9W distributes air in 4 directions at once.

Conditioned air is distributed throughout the room evenly, first distributed along the ceiling, then falling down, it mixes with room air, thereby reaching the optimal and favorable temperature in the air-conditioned room.

Advantages and disadvantages of ceiling-type air conditioners

• saving energy consumption
• ability to program the timer for the desired period of time
• automatic air distribution control
• constant influx fresh air into an air-conditioned space
• power
• noiselessness

• large dimensions
• lack of opportunity hidden installation
• difficult to access for service

Installation of under-ceiling air conditioners

When installing a ceiling air conditioner, you can choose one of the following installation options:

• installation of a multi-flow ceiling air conditioner in the corner part of the ceiling
• installation near one of the walls
• installation in the center of the room

How to choose a ceiling type air conditioner

When buying a ceiling air conditioner, pay attention to models only from proven and well-established manufacturers, because you are going to purchase serious climate control equipment that should serve you for many years. If you want to purchase a truly reliable, modern and multifunctional ceiling-type air conditioner, focus your attention on ceiling air conditioners. Ceiling air conditioners Daikin FUQ-B/RZQ-B9W are compact stylish designs, equipped low noise fans, this is an opportunity to support relative humidity indoors (35-60%) without changing the temperature and many other excellent characteristics that will allow you to create an ideal indoor microclimate.

Development structural versions modern climate control equipment allows interested customers to supply apartments with small and at the same time productive units. The air purification process in split systems also eliminates noise pollution due to the separation of functional units. At the same time, the cassette-type configuration also provides the possibility of maximizing the preservation of free space in the room, which is not hidden by the housing of the indoor module. This is a ceiling split system that is fully integrated into the upper niche. To implement this installation method, a special device is required profile design in the ceiling, but in operational terms this option justifies itself from various aspects.

Features of ceiling models

By and large, this is a classic representative of separate air conditioners, which has all the advantages and disadvantages of this configuration. The main feature of the design is the method of arrangement. The fact is that the air conditioning system is designed for installation in a structure. If you have this frame, there will be no problems with installation, since the very idea suspended structures provides the possibility of integrating communication systems. True, usually we're talking about about hiding the wiring, but if you initially calculate the possibility of installing an air conditioner, then it is quite possible to build in such a housing.

There are also differences from the operation of traditional air conditioners, which can be felt already during operation. Since the ceiling split system, due to its location, can easily cover the entire area of ​​the room, the cooling efficiency also increases.

Main Features

A common advantage for all split systems is unlimited power. Again, dividing modules into external and internal segments allows manufacturers to supply equipment with productive technical stuffing. The ceiling split system is no exception, the power potential of which can reach 16 kW. However, the mid-range still has power ratings in the range of 4-7 kW. These values ​​apply to both cooling and heating performance.

As for the form factor, the choice here is not so extensive. The design most often has a square shape, the base of which is immersed in a niche suspended ceiling. It should be noted that the depth of the housing is usually 25-30 cm. This indicator should be taken into account when calculating installation parameters. Actually, design advantages, which a ceiling split system can have, are expressed only in the appearance external panel. The rest of the structure remains hidden from view.

Floor-ceiling modifications

In addition to the cassette modification, there are other versions that are installed in the upper part of the room. In many operational parameters, such options correspond to the cassette configuration, but their installation is carried out with less labor. In particular, floor-ceiling types of split systems are common, which are used in cases where installation in a niche of a suspended structure is impossible. If we talk about the features of the work process, the air conditioner directs air currents along the walls or ceiling. The user can adjust the dispersion and direction of the jet according to needs. Now it’s worth taking a closer look at the installation nuances ceiling systems.

Installation of air conditioners

The whole process can be divided into three stages. First of all, the external module is mounted. This operation is carried out according to the same scheme as with conventional split systems. Next, a highway is formed connecting outdoor unit with internal. Since the mounting point of the executive segment is located in the suspended ceiling area, the communication wiring can be hidden in advance in this area. On final stage Air conditioners are being installed indoors. Typically, the cassette indoor model is installed as part of installation activities with a suspended structure. First, the climate system housing is attached, and then it is covered with profile components and finishing material.

Maintenance

Among the model maintenance activities of this type We can distinguish general ones, which apply to everything, and special ones, determined by the design of cassette systems. General procedures include periodic filter replacement. You don't need to do this complete disassembly design - the cleaning block is removed through special panel. Also (split systems) during operation leave evaporation on decorative surface. This is the peculiarity of the maintenance of such units - the user is required to clean the panel from traces of settling fumes 1-2 times a month.

Pros and cons of the design

The advantages of ceiling systems include the possibility of hidden installation. As a result, it saves free space indoors and has minimal impact on interior design. Moreover, the aesthetic appearance of decorative panels even decorates and stylistically diversifies appearance suspended structures. But there are also disadvantages that ceiling air conditioners have. Cassette-type split systems, in particular, require special preparation for installation. This can be said about all air conditioners, but the implementation of the installation of this system is simply impossible without the presence of free under-ceiling space.

Conclusion

Giving preference to cassette equipment due to operational advantages and saving space in the apartment, the disadvantages of the divided structure as such should also be taken into account. The fact is that the ceiling-type split system, like all representatives of this family, is not tolerant of installation errors. For example, making a main connection in the ceiling space imposes great responsibility on the contractor. On the other hand, there are also advantages. For example, the design allows for the implementation of a multi-system, which provides one external unit and several internal modules. True, such configurations significantly complicate and increase the cost of equipment. For this reason, multi-systems are more often used in offices, public institutions, supermarkets, etc.
