The professional system intended for conditioning and maintenance of a microclimate in rooms – fankoil. There are several types of such devices which have the features that it is important to consider when choosing suitable options.

Principle of work of a fankoil

To understand how such devices work, for a start we will sort their components:

Heat carriers – provide to the movement of heat fluxes in a system.
The fan – is important for the movement of air masses in highways.
The special block – carries out filtration of the air arriving from the street.
Additional elements for fastening and the control panel still are included in the package.

Even considering scale of a design, process of cooling and heating of air idle time. The principle of work of a system fankoil is based on existence in the ventilating equipment of an intaking opening through which air arrives. It passes through the fan, being cooled up to the necessary temperature, and then passes into the heat exchanger. If fankoil it is connected to forced ventilation, then during it it also mixes up with portion of fresh air. After that air moves to the room.

It is necessary to understand also the main features of a fankoil:

Considering any configuration, it is possible to keep the available house exterior as there is no need to install external conditioners.
The device can be at essential distance from the room to which cold or warm air as the heat carrier or coolant have good thermal capacity will come.
Coolant has no negative impact on human health as it is located in a contour and even at leak the harm is excluded.
If desired fankoil it can be combined with other options of heating, for example, the thermal pump, an electric heating system or a copper.
Users can independently change the modes, creating for themselves the most comfortable conditions.
In operation the units are undemanding, just from time to time it is necessary to purge filters.
The device can be placed indoors with usual ceilings, but at the same time the esthetics will be broken.
Fankoil cannot be considered the self-sufficient device as the additional equipment intended for heating and cooling of air is without fail used. The best the chiller, but this expensive device is considered therefore often it is replaced by thermal pumps.

Types of fankoil

There are several classifications on which it is possible to divide these devices for ventilation. If to be guided by the number of the used heat exchangers, then allocate such types of fankoil: two-pipe and four-pipe. The first option is suitable for the room where mixing of cooling coolant is possible during the operation of the device on heating and cooling. Devices of the second group apply where it is impossible to connect coolants, for example, when it is water and ethylene glycol.

Wall fankoil

Such units have the decorative plastic casing and mount them on a wall. They can work both for heating, and for cooling as everything depends on a type of a system. In most cases the wall ventilatory closer serves as a certain alternative to standard radiators of a water heating system. Units can include also additional functions, for example, drainage, moistening and purification of air. Wall fankoil demands the smallest efforts at installation, but it is important to think over in advance the place that the air flow did not create discomfort.

Floor fankoil

Devices of this group can be installed on a wall and under it, but in most cases for it choose the place under windows instead of the battery. Connection can be carried out by two ways: in a floor and a wall. The conditioner fankoil directs an air flow along a wall up. If the unit works for heating, then such movement of air provides thermal protection of windows and walls, and when cooling it will reduce heatinflows. Floor devices can have the built-in or remote governing bodies.

Ceiling fankoil

One of the most widespread options of placement – on a ceiling. Thanks to the small height of the device, it can be established in rooms with the small height of ceilings. The device will not reduce useful area, and all components will be hidden by hinged designs. Fankoil to the apartment is issued in case and packageless option. The second type (there are cassette and channel models) is more available at the price, but they are of a lower quality nothing. Installation can be hidden and open.

Cassette fankoil

By means of such device it is possible to receive uniform distribution of air in two and four directions.

The most popular models release in compact cases of 60х60 cm in size, but if to establish more powerful options, then dimensions will be more.
The ventilatory closer of cassette type is placed on a ceiling and rooms with a big area, for example, in shopping centers.
For the best functioning it is better to attach air ducts to forced ventilation.
That cold air moved with a comfortable speed, the device has to be at the height at least 2.7 m from a floor.
When installation is finished, fankoil close the false-panel.
As for refrigerating capacity, it no more than 5 kW.
Carry the simple system of removal of the formed condensate which is created on the basis of drainage pumps to advantages of this type of a fankoil.

Channel fankoil

Devices of this group have the hidden installation and externally they are similar to internal blocks channel a Split systems. Only decorative lattices are outside removed, and all components are hidden in a ceiling or a wall. Such ventilatory convectors differ from channel in the fact that it is possible to create network of air ducts which provide air supply from several lattices at once thanks to what it is possible to cool and warm up air in several rooms at once.

Channel fankoyla are established mainly in office, public and office buildings.
Devices have the wide range of refrigerating capacity therefore to choose is from what.
It should be noted an important technical characteristic – a pressure of the built-in fan. There are devices highly - and low pressure type. Thanks to it it is possible to provide with cold air of the room which are located close and remotely from the unit.

Built-in fankoyla

Similar devices can be found among wall and ceiling models. To a thicket they are established in a false or stretch ceiling. The built-in room fankoyla are attractive that the device is most hidden, that is only the lattice through which there is an air is visible. Thanks to it the equipment does not spoil design of the room and does not break its harmony.

Universal fankoil

Devices of this type can be installed both in horizontal, and in vertical position. If to compare appearance, then it the same, as well as internal block of the ordinary conditioner, but on functions of difference nevertheless are available: in the heat exchanger liquid circulates and there is a three-running valve which is responsible for supply of coolant or the heat carrier. For conditioning fankoil is established in most cases indoors without false ceilings. Generally indicators of refrigerating capacity are at the level from 1 to 8 kW.

Service life of a fankoil

At each device the service life as it depends on the sizes, power, components and other indicators. This information is surely specified in passport data of the device. In most cases the device of a fankoil of ventilatory type will serve 8-10 years. It is important to pick up correctly model for parameters, and it is still regular to carry out scheduled maintenance on service of the unit thanks to what it will be possible to increase the term of its service significantly.

Calculation of power of a fankoil

Difficult and exact calculations of power are carried out by experts, but there is a simple option. It is important to consider that final power has to consider the hidden warmth, so, with an arid climate the error is in regions at the level of 20%, and at the increased humidity it can make 50%. Organize cooling and heating of a fankoylama taking into account such data:

Office rooms with office equipment and computers require the device at which power will be 150 W on each 1 sq.m.
For premises at which height of a ceiling is 2.7-3 m, it is necessary to choose units with a performance on cold in 100 W on each 1 sq.m.

Installation of fankoil

As systems are difficult installation and setup of such units experts have to be engaged. Only in this case it is possible to count on high-quality installation, they will correctly make all calculations, having considered functional loading and features of each room. Ventilatory closers of a fankoyla are installed according to such scheme:

Installation of the device on the most favorable place in the concrete room.
Assembly of knots of a binding with establishment of necessary cranes, valves and devices for control of temperature and pressure.
Laying and further thermal insulation of pipes, and then installation of a system for removal of the accumulated condensate.
Connection of devices to an electrical network and pressure testing of a system. The tightness of all knots is without fail checked.
At the end giving of the carrier is made. As a result the system, safe and trouble-free in respect of work, turns out.

Control of fankoil

The main control and check of work of a system is carried out by experts at installation of the unit. For operation of internal blocks special panels, knots and panels are used. With their help the device will stop when the set temperature is reached and to restore activity when indicators fall. Electric fankoyla thanks to the modern scheme of automatic adjustment are capable to perform such functions:
