Fancoil channel: the principle of operation and installation

Recently, the channel fan coil has become more common among consumers. This device is an equipment that has the ability to heat or cool indoor air at the user's will. Simply put, such an aggregate can be called a heat exchanger, which can be installed in any building of any purpose, it will allow selecting a certain temperature regime at any time, which will be comfortable for people inside the building.

Design features

The fan coil can have various design features, but most often the models consist of a filter element, a heat exchanger, a fan, a heating electrical element and a control panel for the equipment. With regard to the filter, it is able to protect the system from ingress of foreign particles that can penetrate with the air masses. The heat exchanger allows to effectively cool or heat the air, which will depend on the installed mode of operation of the equipment at a certain moment. The fan provides a flow of air that is pumped through the heat exchanger.

Principle of operation

If you decide to purchase a fan coil, you should first become familiar with the principle of its functioning, which consists in that the air is cooled and heated depending on the chosen mode of operation. The air masses are driven by the fan through the heat exchanger. Air flow is not created from the air masses that are present in the room, but from the fresh air that is supplied from the chiller. The last element acts as a central component when creating an air-conditioning system. In the chiller air masses come from the air-supply unit, which carries out the air intake from the outside.

Main advantages of the system

Fancoil channel has a lot of advantages, among them it is possible to provide full cooling or heating of the room within five minutes after the system start-up. This possibility is guaranteed by the simultaneous installation of a fan coil and chiller. Among other things, the system allows creating a comfortable microclimate in the rooms where the fan coil is mounted. Owners of apartments, houses or buildings will be able to save electricity.

Among the additional features can be identified the possibility of connecting to the chiller of a different number of fan coil units. But the step of the route from the chiller to the most distant fan coil can not be more than six hundred meters. A channel-type fan coil allows you to save the money that is required to create pipe runs when choosing water as a carrier.

Lack of system

Before installing the system, you must understand that the arrangement has one significant disadvantage, which is expressed in the absence of the ventilation function of the building. That is why there is a need to create a parallel system that will ensure forced air circulation.

Choosing a variety of fan coil before installation work

If you decide to install a channel-type fan-coil in the building, you should determine what classification the system should have. To date, the market presents four types of designs, namely: console type, cassette, horizontal type, as well as console type, enclosed in the body. Each of these heat exchanger systems can be installed indoors using different technologies: the elements can be hung on the wall, integrated into the ventilation system of the building, installed on the floor or suspended on the ceiling. As the main features of the fan coil, which affect the choice of a certain device, the overall air productivity, as well as the performance of cold air, are performed.

Characteristics of two-pipe and four-pipe systems of heat exchangers

Before installing a ducted fan coil, you need to determine whether a two-pipe or four-pipe heat exchanger system that uses water as a carrier will be used. The simplest scheme of strapping is a two-pipe system, because of this it is so common. With it, you can cool the air indoors, and the cost of the device will be relatively low.

For the winter period, a two-pipe fan coil can be switched to heating mode, but for this it will be necessary to disconnect the chiller pipes and then connect them to the central heating. This function can be performed with a special valve, which is manually adjusted.

The four-tube system has two heat exchangers in its composition, one of which is connected to a system with a hot carrier, while the other is connected to a chiller. This scheme of strapping is characterized by more complex design features, this affects the price of the fan coil, which is why consumers often refuse to purchase this equipment.

A four-tube ducted fan coil can cool or heat indoor air, and you do not have to make particularly difficult pipe switching, you only need to select a specific mode by using the equipment control panel. This is very convenient, according to the assurances of users who have used a similar system for heating or cooling air for quite some time.

Wizard's recommendation for installation

The four-tube ducted fan coil, the principle of operation of which has been described above, is best placed near the windows, as this will compensate for losses from warm air through the window openings. As you know, most of the heat flows through windows, which is why this approach can be called a very effective solution.

Mounting technology

Before starting work, you should definitely consider the connection scheme of the ducted fan coil, this will eliminate errors, especially for inexperienced novice masters who have not previously encountered such tasks. In view of the fact that the system in which the chiller and fan coil are present differs with rather complex design features, installation work and adjustment are best entrusted to highly professional specialists. They will be able to perform the installation, having carried out the competent installation of equipment in the place where its work will be most effective. In this case, you can use the warranty and service. Most often, supplier companies guarantee full service in case of breakdowns during the day.

If you yourself plan to deal with these manipulations, then in the next step it will be necessary to assemble the bundling units, and this will be possible after installing the necessary valves, cranes and pressure and temperature monitoring devices, which is very important task. The next step will be the installation and insulation of the pipe, as well as the installation of an evacuation system that will protect the system from premature failure even before the end of the warranty period. When a high-pressure ducted fan coil is installed, it will be necessary to perform the manipulations to connect the devices to the mains. The system should be pressurized, and its tightness checked.

The last stage is the supply of water, which acts in the system as a carrier. Before determining the service side of the Clint duct fan coil, it is worth considering whether you will be able to make all the necessary calculations that are necessary to carry out the work. They will allow to take into account the functional load that will be provided to a particular fan coil. Among other things, specialists will help to determine the features of each room in the building, which allows you to choose the right equipment for maximum efficiency.

Why choose a fan coil?

If you decide to install a fan coil in the room, you will find a heat exchanger inside which there is a fan. All the components listed above are enclosed in one compact package, which looks very aesthetically pleasing and does not take up much space, in particular when it comes to installation on the ceiling. That's why experts advise to resort to such a decision. By installing this system, you can simultaneously resolve the issue of air conditioning and ventilation, which saves money for the purchase of appropriate equipment. The equipment works with minimal noise and does not involve complicated maintenance, which is undoubtedly an indisputable plus.

Conclusion

After all the installation work is done, regardless of whether you are doing them yourself or trusting experienced masters, you will be able to use a system that will be distinguished by durability, trouble-free operation and safety in action. This will allow you to make sure that the system "fan coil-chiller" is the most effective, reliable and economical. It does not imply carrying out particularly complex operations on installation and setup of the system. In order to ensure effective work, it is best, of course, to involve in the installation of employees of the relevant organization, which specializes in the creation and arrangement of such systems. This will allow you to exclude premature repairs.
