Recently, channel fan coil is becoming more common among consumers. This device is an equipment that has the ability to heat or cool indoor air at the request of the consumer. Simply put, such a unit can be called a heat exchanger that can be installed in any building of any purpose, this will allow you to choose a specific temperature at any time, which will be comfortable for people inside the building.
Design Features
A channel fan coil can have various design features, however, most often models consist of a filter element, a heat exchanger, a fan, a heating electric element and a control panel for equipment. As for the filter, it is able to prevent the system from getting inside of foreign particles that can penetrate together with the air masses. The heat exchanger allows you to effectively cool or heat the air, which will depend on the installed mode of operation of the equipment at a certain point. The fan provides a stream of air that is forced through the heat exchanger.
Principle of operation
If you decide to purchase a channel fan coil, you should first familiarize yourself with the principle of its operation, which consists in the fact that the air is cooled and heated, depending on the selected mode of operation. Air masses are driven by the fan through the heat exchanger. The 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 in creating the air conditioning system. The air masses come into the chiller from the supply unit, which carries out air intake from the outside.
The main advantages of the system
Channel fancoil has a lot of advantages, among which we can single out the provision of full cooling or heating of the room five minutes after the system starts. This possibility is guaranteed by the simultaneous installation of a fan coil and a chiller. Among other things, the system allows you to create a comfortable microclimate in the rooms where the fan coil is mounted. Owners of an apartment, house or building will be able to save energy.
Among the additional features, it is possible to highlight the ability to connect to the chiller a different number of fan coils. But the step of the track from the chiller to the most remote fan coil cannot be more than six hundred meters. Channel-type fancoil allows you to save money that is required to create pipe routes when choosing water as a carrier.
System flaw
Before installing the system, you should understand that the arrangement has one significant minus, 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 provide forced air circulation.
Choosing a variety of fan coil before installation
If you decide to install a channel-type fan coil in the building, you must decide what classification the system should have. There are four types of designs on the market today, namely: the cantilever type, cassette, horizontal type, as well as the cantilever type enclosed in the case. Each of these heat exchanger systems can be mounted in the room according to a different technology: the elements can be hung on the wall, built into the ventilation system of the building, installed on the floor or suspended from the ceiling. The main features of the fan coil, which affect the choice of a particular device, are the overall air performance, as well as the performance of cold air.
Characteristics of two-pipe and four-pipe heat exchanger systems
Before you install the channel fan coil, you need to decide on whether the two-pipe or four-pipe heat exchanger system that uses water as a carrier will be used. The simplest strapping scheme has a two-pipe system, because of this it is so common. Using it, you can cool the air inside the room, and the cost of the device will be relatively low.
For the winter period, the two-pipe fan coil can be switched to heating mode, however, for this it will be necessary to disconnect the pipes from the chiller, and then connect them to the central heating. This function can be carried out using a special valve, which is manually regulated.
The four-pipe system has two heat exchangers in its composition, one of them is connected to the system with a hot carrier, while the other is connected to the chiller. Such a strapping scheme is characterized by more complex design features, this affects the increase in fan coil prices, which is why consumers quite often refuse to purchase this equipment.
A four-pipe channel fan coil can cool or heat the air in the room, and you don’t have to make particularly difficult pipe switching, you only need to select a certain mode using the equipment control panel. This is very convenient, according to users who have been using a similar system for heating or cooling air for quite some time .
Installation wizard recommendation
The four-pipe channel fan coil, the principle of which was described above, is best installed near the windows, as this will compensate for losses from warm air through the window openings. As you know, most of the heat leaves through the windows, which is why this approach can be called a very effective solution.
Installation Technology
Before starting work, you should definitely consider the connection scheme of the channel fan coil, this will eliminate errors, which is especially true for inexperienced novice masters who have not previously encountered such problems. Due to the fact that the system in which the chiller and fan coil are present differs in rather complex structural features, it is best to entrust the installation work and configuration to highly professional specialists. They will be able to complete the installation, having carried out competent installation of equipment in the place where its operation will be as efficient as possible. In this case, you can take advantage of the warranty and after-sales service. Most often, supplier companies guarantee full service in case of breakdowns during the day.
If you plan to deal with these manipulations yourself, then at the next stage it will be necessary to assemble the binding units, and this can be done after installing the necessary valves, taps and pressure and temperature control devices, which is a very important task. The next step will be the installation and insulation of the pipe, as well as the installation of the condensate drainage system, which will protect the system from premature failure even before the end of the warranty period. When a high-pressure channel fan coil is installed, it will be necessary to carry out manipulations on connecting the devices to the power supply network. The system must be tested, and its tightness checked.
The last step is the supply of water, which acts as a carrier in the system. Before determining the service side of the Clint channel fan coil, it is worth considering whether you can carry out all the necessary calculations that are needed to carry out the work. They will allow you to take into account the functional load that will be on one or another fan coil. Among other things, experts will help determine the features of each room in the building, which allows you to choose the right equipment for the most efficient operation.
Why choose fan coil?
If you decide to install a fan coil in the room, then you will find a heat exchanger, inside which there is a fan. All the components listed above are enclosed in one compact case that look very aesthetically pleasing and do not take up much space, in particular, this applies to the case when the installation is made on the ceiling. That is why experts advise resorting to such a solution. By installing this system, you can simultaneously solve the problem of air conditioning and ventilation, which saves money on the purchase of appropriate equipment. The equipment operates with minimal noise and does not require complex maintenance, which is undoubtedly an indisputable advantage.
Conclusion
After all installation work is completed, regardless of whether you will do it yourself or entrusted to experienced craftsmen, you will get the opportunity to use a system that will be distinguished by durability, trouble-free operation and safety in operation. This will allow you to make sure that the "fan coil unit" system is as efficient, reliable and economical as possible. It does not involve particularly complex installation and commissioning operations. In order to ensure efficient operation, it is best, of course, to involve the employees of the corresponding organization that specializes in the creation and arrangement of such systems for installation. This will allow you to eliminate premature repairs.
