Fan coils Comfort Deluxe scheme. Fan coil channel: principle of operation and installation

Currently, the population is highly popular with the installation of fan coils - devices capable of cooling or heat the air indoor. Such a device (Simply put, heat exchanger) can be installed in each room of the building, which allows you to choose an individual temperature mode At the request of people in it. Despite the differences in the designs of these aggregates, they all consist of:

  • a filtering element that protects the fan coil system from entering it along with air of foreign particles;
  • the heat exchanger itself, with the help of which the air indoors will be cooled or heat up, which depends on the selected mode of operation of the device;
  • fan providing a forced air flow through the heat exchanger;
  • electrical heating element;
  • control panels (panel).

How do the device data work?

Principle of operation

Air, driven by a fan through the fan coil heat exchanger, is heated or cooling depending on which mode of operation is selected. In this case, the air flow is created not from the air mass, which is present in the room, and from fresh airSupported from a special car - chiller, which is a central unit when creating a system of air conditioning or heating of all buildings of the building with fan coils. In Chiller, the air gets from supply installationexcavating the air intake from the street.

What is the advantage of such a central air conditioning system?

Advantages of the Fan Coil Chiller system

The simultaneous installation of fan coils and chiller allows you to create a system that:

  1. It will provide complete heating or cooling of the room, 5 minutes after it starts.
  2. It makes it possible to create a comfortable microclimate in any of the premises where Fan coil is installed, at the request of people in this room.
  3. Allows you to save electricity.
  4. Provides the ability to connect to one chiller unlimited number of fan coils. However, the distance of the highway from chiller to the very remote funky is limited to a parameter of 600 m.
  5. It makes it possible to save money necessary to create pipe trails when choosing water as a carrier. However, the creation of such a system in the construction has one very significant disadvantage - it does not perform the function of ventilating the room. Therefore, it must be created in parallel with the system forced air circulation in the construction.

Industry offers consumers to choose a few different types Fan coils.

Classification

You can determine which devices to you most suitable for installation, knowing their parameters and operational characteristics.

Currently you can choose from four different designs of Fan Coils:

  1. Console type.
  2. Console type in the case.
  3. Cassette type.
  4. Horizontal type.

All these types of heat exchangers can be installed indoors in the most different way:

  • hang on the wall;
  • installed just on the floor of the room;
  • instruct B. ventilation system building;
  • mounted in hinged designs of the ceilings.

The main characteristics of the fankyl, which affect the selection of one or another device are:

  • cold air productivity;
  • overall air performance.

In addition, heat exchangers that use water as a carrier can be:

  1. Two-pipe. This strapping scheme is the simplest and most common. It allows only cooling air indoors. Therefore, the cost of such an appliance will be low. IN winter Two-pipe fans can be translated into heating mode, but for this pipe, it is necessary to turn off from the chiller and connect them to the central heating system. This feature performs a special valve adjustable manually.
  2. Four-pipe. This system It has in its composition two heat exchanger, one of which is connected to the chiller, and the second to the system with a hot carrier (the central heating system). This strapping scheme is more complex. Therefore, the price of such a fan coil will be higher. This system allows either cooling the air in the room, or heat it, without producing complex pipe shutdowns, but only by selecting the required mode on the instrument control panel. Such fan coils are best mounted in the windows area, because it will be compensated for the loss of heat through the glasses.

FEATURES OF MONTAGE

Taking into account the complexity of the fan coil-chiller systems, highly professional specialists should be engaged in installing and configuring. Only they will be able to perform high-quality installation of fan coils, producing competent:

  • installation of the unit in the place where its work will be the most efficient as possible;
  • assembling nodes of the strapping by setting the necessary cranes, valves, temperature control devices and pressure;
  • gasket and thermal insulation of pipes;
  • installation of the condensate removal system;
  • work on connecting devices to the power grid;
  • crimping system and verification of its tightness;
  • the supply of carrier (water).

They will produce all required calculations Before starting work, taking into account what functional load will perform one or another fan coil, as well as the peculiarities of each room in the construction.

After performing the installation work, experienced masters you will get the opportunity to use the system that will be safe, trouble-free and durable.

Thus, you were able to make sure not only that the fan coil-chiller systems are very effective, economical and reliable, but also that they require complicated installation and commissioning operations. And for this it is necessary to attract employees of organizations specializing in creating such "turnkey" systems.

Initially, it should be noted that without the presence of project documentation is not allowed to install any funky. Any replacement of one species on another type or firm manufacturer of Fan Coil must be agreed with designers, otherwise it can lead to the failure of Chiller himself.

Connecting funky in several stages

First stage- This is the installation of the fankyl itself to the place allotted in the project, followed by connecting it to the system of pipelines of supplying water (or any other coolant). Again, you should take all the characteristics laid in the project.

  • You can not change or change the diameters of pipelines, the material from which the pipes should be made, which will definitely affect the flow rate of the coolant through the fan coil and in the future on the performance of the chiller itself.
  • It is impossible to install the installation not provided by the project, valves, adapters or other hydraulic circuit elements, as well as not to install the same elements.
  • It must be remembered that when the fan coil on its heat exchanger is formed, condensate is formed and this condensate should be displayed in the sewage system.
  • To eliminate the stagnation of condensate in drainage pipelines during its laying, it is necessary to withstand the slope of 1 degree in its lattice throughout the drainage pipeline.
  • To completely eliminate failures and the formation of congestion zones.
  • In the sewage system, there are no pleasant smells and the ingress of these odors through the drainage pipeline into fan coil, and then it is also necessary to exclude, providing a water shutter or a plasticized device on a drainage pipeline.

Second phase. Since the channel fan coils are different by the type of location, the most difficult at this stage is the connection of fan coils to air ducts.

  • Not all channel funkowns can be connected to air ducts, so this stage concerns those who have such a connection. If the channel fan coil requires the connection of the air ducts, then at this stage there is such a connection for which the air comes to the fan coil itself, and for which the prepared air enters the room after the fan coil. In addition, it is necessary to pay attention to the air duct that provides the influx of fresh air if it is laid in the project.
  • The material and section of the air ducts can be different and therefore these parameters of the air ducts follow according to what is laid in the project documentation.
  • Attention should be paid to the length of the air ducts in which the air should come from the room and to the room. This length is directly related to such technical characteristic Fan coil as static pressure. An increase in the length of the air ducts can lead to a decrease in air flow.

Third stage. Fan coil is connected to the power supply network.

  • Before connecting, it would be nice to pay a little time to verify the compliance of the fankyl voltage and the network to which you should connect. The automatic, through which the fan coil should be connected or several fans should be slightly larger (by about 15-20%) for current strength (amperes) than all the funkowns connected to it. You can use the formula of grade 6 to calculate the power of the automaton. P \u003d u * i Where i \u003d p / u. Where p is the electrical power of the connected fan coils; U - voltage in the network (usually 220 V); I - current (amps), which must match the machine through which is connected.
  • We must not forget that it is necessary to connect all three wires especially the third - grounding.
This type of work should not trust random people who are not certified to keep such work, thereby remember that "the miser pays twice."

Recently, fankyl channel is becoming more common in consumers. This device is an equipment that has the ability to heat or cool the air indoors at the request of the consumer. Simply put, such an aggregate can be called a heat exchanger that can be installed in any place of construction of any destination, this will allow you to choose a certain temperature at any time that will be comfortable for people inside the building.

Constructive features

Fan coil can have various design features, but most often the models consist of a filtering element, heat exchanger, fan, heating electrical element and equipment control panel. As for the filter, it is capable of protecting the system from entering outsiders, which can penetrate with air masses. The heat exchanger allows you to efficiently cool or heat the air, which will depend on the installed mode of operation of the equipment at a certain point. The fan provides air flow that is injected through the heat exchanger.

Principle of operation

If you decide to purchase a channel channel, you should initially familiarize yourself with the principle of its functioning, which is that air is cooled and heated depending on the selected functioning mode. Air masses are driven by a fan through the heat exchanger. The air flow is not created from which are present in the room, but from fresh air, which is served from Chiller. The last element acts as a central component when creating in Chiller, air masses come from the supply unit, which carries out the air intake.

The main advantages of the system

Fan coil has a lot of advantages, among them you can select the provision of full-fledged cooling or heating of the room after five minutes after the system is started. This feature is guaranteed by simultaneous installation of fankial and chiller. Among other things, the system allows you to create a comfortable microclimate in rooms where fan coil is mounted. The owners of the apartment, houses or buildings will be able to save electricity.

Among the additional features, you can select the ability to connect to the chiller of different amounts of fan coils. But the step of the highway from Chiller to the most remote fan coil can not be more than six hundred meters. Channel-type fan coil saves cashRequired to create pipe trails when choosing water as a carrier.

Lack of system

Before installing the system, you must understand that the arrangement has one essential minus, which is not expressed in the absence of a building ventilation function. That is why there is a need to create a parallel system, which will ensure forced air circulation.

Choosing a variety of fankial before assembly work

If you decide to install a channel-type fan coil in the building, you must decide which classification system should have. Today, four varieties of designs are presented on the market, namely: console type, cassette, horizontal type, and a console type enclosed in the housing. Each of these heat exchangers can be mounted in the room by different technology: items can be hung on the wall, embed the building in the ventilation system, install on the floor or hang on the ceiling. As the main features of fankyl, which affect the selection of a certain device, perform overall air performance, as well as cold air performance.

Characteristics of two-pipe and four-pipe heat exchangers

Before you are installed in the installation of channel fan coil, it is necessary to determine the two-pipe or four-pipe heat exchanger system, which uses water as a carrier role, will be used. The simplest pattern of strapping has two-pipe system, Because of this, it is so common. With it, it is possible to cool the air indoors, and the cost of the device will be relatively low.

For the period of winter two-pipe fankyl It is possible to translate into heating mode, however, it will be necessary to turn off the pipes from the chiller, and then connect them to the central heating. This function can be performed using a special valve, which is adjusted manually.

The four-pipe system has in its composition heat exchangers in the number of two pieces, one of them is connected to the system with a hot carrier, while the other is to the chiller. Similar pattern of strapping is characterized by more complex constructive featuresThis affects the increase in the price of fankyl, that is why consumers often refuse to acquire this equipment.

Channel four-pipe fan coil can cool or heat the air indoors, and you will not have to produce particularly complex pipe switches, you will only need to select a specific mode using the equipment control panel. It is very convenient, according to user assurances that have long used a similar system for heating or

The four-pipe channel fankyl, the principle of operation of which was described above, it is best to install near windows, as this will allow you to compensate for the losses from warm air through 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.

Montage Technology

Before starting work, you must necessarily consider the connection diagram of the channel fankylene, this will eliminate errors, which is especially concerned with inexperienced beginner masters, who have not previously encountered with the solution of such tasks. Due to the fact that the system in which the chiller and fan coil is present is quite complex constructive features, mounting work And the configuration is best to entrust highly professional specialists. They will be able to install, carrying out the competent installation of the equipment in the place where its work will be the most efficient. In this case, you can use the warranty and service. The most common supplier companies guarantee full service in case of breakdowns during the day.

If you yourself plan to do these manipulations, then at the next step it will be necessary to assemble the nodes of the strapping, and it can be done after installation required valves, Cranes and pressure control devices and temperature, 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 discharge system of the emerging condensate, which will protect the system from premature failure before the end of the warranty period. When high-pressure channel fan coil is installed, you will have to make manipulations to connect the devices to the power supply network. The system must be crimped, and its tightness is checked.

The last step is the flow of water, which acts in the system as a carrier. Before determining the side of the maintenance of channel fankyl CLINT, it is worth thinking about whether you can implement all the necessary calculations that are needed for work. They will allow you to take into account the functional load, which will be provided on this or that fan coil. Among other things, experts will help identify the features of each room in the building, which allows you to choose the way to choose the equipment for the most efficient work.

Why should I choose Fan Coil?

If you decide to install fankyl indoors, then you will find a heat exchanger inside which there is a fan. All listed components are enclosed in one compact housing, which look very aesthetically and does not occupy a lot of space, in particular, this concerns the case when the installation is made on the ceiling. That is why experts advise to resort to such a decision. By installing this system, you can simultaneously solve the issue with air conditioning and ventilation, which saves cash to the purchase of relevant equipment. The equipment works with minimal noise and does not imply complex maintenance, which is undoubtedly an indisputable plus.

Conclusion

After everyone is fulfilled, regardless of whether you will deal with them yourself or beat experimental mastersYou will get the opportunity to use the system that will differ in durability, trouble-free operation and security in action. This will allow you to make sure that the "Fan Coil-Chiller" system is the most efficient, reliable and economical. It does not involve particularly complex installation and commissioning operations. In order to ensure efficient work, the best of all, of course, to attract employees of the relevant organization, which specializes in creating and arranged such systems. This will allow you to exclude premature repairs.

Can work in two modes: to heat the room and cooling. In this regard, there are the following versions of the chiller-funk system:

- two-pipe system: in this case, cooling in the summer and heating in the offseason is carried out at the expense of the chiller. Sometimes the system includes parallel with chiller thermal devices for heating in winter.

- Four-pipe system: Fan coil is capable of working in two modes (heating / air cooling indoors), and water from the heating system is used for heating mode.

The two-pipe system is a fan coil with one heat exchanger. The most common and trivial strapping scheme. One pipe is connected to the fan coil for the receipt of chilled water into the heat exchanger, the other - for her removal to Chiller (" reverse water"). In winter, a two-pipe system can be used to heat the room, the pipes are summed up to the boiler or to the heat supply system from urban boiler rooms, and the water supply from the chiller does not come. In the summer, the flow of water from the boiler blocks a special valve, and the fan coils work on the water coming from Chiller. Thus, the system is allowed to mix the heat and coolant.

Dual-pipe Fan Coil Connection Scheme:

Simplified strapping scheme of 2 pipe fan coils (Calrifer):

Designation in the Scheme:

1 - ball valve.

2 - filter.

3 - 3 chassing control valve with a drive.

The two-pipe system is cheaper than four-pipe, but for its work, if it is necessary to prevent mixing the coolant, water will have to be warm in an additional heat exchanger from the heat supply system and an additional circulation pump is necessary. And these are even additional operating costs. For supplying thermal energy in the offseason, a reversible chiller can be used (working in heat-cold mode), which is able to heat the water independently.

This strapping scheme of Fan Coils will serve as an excellent solution for offices, warehouses and during the reconstruction of buildings, where it is not always possible to pave a complex pipeline system with large quantity nodes.

Four-pipe Fan Coil Connection Scheme:

The four-pipe system is a two-kinned fanoxium (that is, with two heat exchangers). In this system, each heat exchanger is connected to a pipeline with a cold and hot heat carrier, respectively, each of the heat exchangers has its own valve for the fan coil strapping, which are controlled by a remote control for fan coil. This system is used when the colaster (for example, ethylene glycol) cannot be mixed with the coolant.

The circuit of the strapping of four-pipe fan coil is a dual pattern of strapping for 2 tube fan coils.

The four-pipe scheme of the strapping of fan coil provides an administrative building to their year-round operation, in the off-season warm water in the contour can also come from chiller, which works as a heat pump. In winter, hot water is circulated in an additional heat exchanger, which comes from the central heating system. The temperature of the coolant to the heating season ranges from 70 ° C to 95 ° C, which exceeds the permissible operating temperature for most of the fan coils, so it must be reduced to pre-reduce it.

From Chiller, a coolant is entered on all fankowns installed on each floor of the building. Hot water Comes from the city heating network to all Fan Coils through a special heat point, which, as a rule, is installed in the basement.

When designing the Chiller-Funkyla system, first of all, it is necessary to decide on the connection scheme of fan coils and make calculation hydraulic system. This should only do a heat engineer engineer. After determining the insularity for each room, the specialist is already selecting the chiller (with a built-in hydraulic circuit or without) and the fankeal of the desired cooling capacity, and also designs the fan coil circuit.
