Punching of the sole source of cold and heat for home permanent residence Chiller is used mainly in the southern regions. Avto for heating dwellings in the middle lane and northern latitudes of Russia specialists are more often recommended for the winter to switch the fan coil network for power from the boiler using the appropriate valves on the feed and return pipelines. The best results with this method of heating can be achieved if the funkowns are installed in all heated rooms under the windows. The thing, even if it is located behind the polar circle, it will be warm with very strong frosts and when the fan coil fans are turned off.

4. In the climate system "Chiller-Fan and Funky" includes a refrigerating machine (a), in summer, the cooling coolant is up to 6-7c. The pump drives this fluid on pipes (b) through the heat exchangers of fan coils (B), which are conditioned by air in the rooms.
5. Channel models of fan coils intended for vertical installation are often mounted under the windows, in niches closed with drywall panels.
6-7.Montamine channel fan coils in niches simplify the box VentilCassaForma (Aermec).
Integration of the "Chiller-Fan and Funkyla" system and a supply ventilation unit can be integrated. Chiller and boiler are connected to the latter to the latter. The result is the trifold air accordingly, it is cooled or heated, and then the air ducts comes directly into the room or in fan coil, in addition to the air involved in them from the premises. Passing additional processing in fan coils, enriched with street air, the mixture will be distributed through the rooms using the fan coil output grilles. Another possible consumer of cold water is coolers of medium-temperature refrigeration chambers and wine rooms. Some chillers models (with heat utilization) are equipped with additional heat exchangers, so that in summer they can simultaneously produce cold and hot water. The latter is used to heal water in the pool, water intended for the GVS system, IT.P.
Two sides of the medalCompared to freon air-conditioning systems (in particular, multi-member) chiller-fan-cooled installations are more environmentally safe. After all, the heat and cold carrier in them is not freon, but ordinary water. If this liquid falls into the room, nothing terrible will happen. Avto When an emergency leakage of a significant amount of freon in a residential premises, people there may be poisoned from the Main Freonon Power Plant. If at least once to inhale the freon derivatives formed during its contact with fire (for example, in case of fire), more severe consequences are possible.

In fairness it should be noted that the chiller also contains a bit of freon (several kilograms), but the freon contour in models used for country houses is usually on the street or in the technical room, where only specialists for service maintenance are surrounded.
Another advantage of chiller-fanochal systems is their scalability. The number of air-conditioned rooms can be chosen at will. If there are many of them, a powerful chiller and pumps will be required, and therefore energy supply at the rate of 1kW of electrical power by 25-35m2 air-conditioned area.

Judge If the building is built and insets not immediately, and gradually, it is possible to start equipment in incomplete power mode. With the emergence of new riddled premises to equip them with additional fan coils, adopting the latter to the already existing system. The distance between chiller and fancoali depends only on the power of pumps in the system, so that the chiller can be placed in the attic, in the basement, on the roof, on the site (even a few hundred meters from the housing).

Fan coil clutter models are mounted in large rooms. Their body is partially hidden behind the suspended ceiling, located from the slab of the overlap by 450-500mm. These devices evenly distribute air in four directions. Good consumer characteristics are different, for example, Cassette closers WKW (Wesper) (16), Melody (CIAT) (17), 42GWC (CARRIER) (18), GCAF (GENERAL CLIMATE) (19).
Among the minuses of the described technique, we note first of all its high cost. For country houses, the purchase and operation of the chiller-fan-coil installation is at least 1.5-2 times higher than when using freon systems. On the dimensions of Fan coil is noticeably larger than the split system similar to the cooling capacity, and this is especially noticeable if equipped equipment for open-ended installation. Cool (however, as heated) Fan coil rooms slower than freon air conditioners. Finally, another inconvenience gives a lot of trouble, pipelines can be piping, with which the fan coat is connected to the chiller and the condensate is discharged, formed during cooling, they need to be thermally insulated and hiding into the walls, which is not possible everywhere. Because of this, it is necessary to construct to disguise the communications of false structures.
Next, we briefly consider the design features of chillers and fan coils used in the system of climation of country houses.
Ready solution for a country house
The Altherma system (Daikin) provides heating, air conditioning, as well as the preparation of hot water for a country househouse in the assortment of most leading climate technology producers, you can find reversible low-power chillers (5-16 kW), adapted for country houses with an area of 50-150m2. They can work with a small network of fan coils, and with ceiling cooling systems. However, the special emphasis equipment suppliers make on its ability to act as a heat generator for a country house (both "alone" and together with other sources of solar collectors, IT.D. boilers), heat the heat carrier for warm floors and radiators, as well as Water for the DHW and the pool system.
So, the company Daikin in 2005. He released the Altherma to the European market. The composition includes a chiller with a thermal pump mode with a capacity of up to 7kW (it is supplied as a compressor-capacitor unit), EKHBH hydrojodule (heating only) or EKHBHX (cooling / heating) with a remote evaporator "Freon / Water" and EKSWW tank for hot water supply ( DHW) for 150, 200 or 300l. The rest of the equipment, including fan coat, pipes and strapping for water radiant heating and cooling systems, are offered both daikin and other firms. Mitsubishi Electric actively promotes reversible chillers in the mono- and double-block (compressor-capacitor block plus a remote evaporator) of the Zubadan Inverter series of cold and thermal production 5-16 kW. The required component of systems created on the basis of these chillers is the PAC-IF021B-E controller.
So, in September 2008 In the Leningrad Region, the company "Source" (Russia) has established a reversible chiller Zubadan Inverter (PUHZ-HRP71VHA model with a power of 8-11,2kW). It is used to heat the private house with an area of 72m2 and works on the radiator heating system filled with propylene glycol. This installation functioned without problems at -25c (especially coldly issued several days at the end of January 2009) - in heated premises, the temperature 21c was maintained. It is characteristic that when it was -3 on the street ...- 8c, the Zubadan Inverter system consumed only 1,89 kw electricity for 1 day. Such high indicators probably managed to achieve thanks to the high efficiency of the equipment used and good thermal insulation of the building (enclosing houses - from foam concrete 200mm thick, which is used as a heater, 50mm thick, as well as mineral wool URSA thick 100mm).
Heart of coldChiller, like a good car, usually completed strictly under a specific customer. Therefore, its power and equipment always accurately correspond to the operating conditions on a particular object. Most often in rustic construction, models with air cooled capacitor with a capacity of 5-80kW are used. They produce hundreds of companies. The Russian market equipment supplies companies such as Aermec, Blue Box, Clivet, RC Group, Rhoss (All Italy), Airwell, Ciat, Trane, Carrier (USA- France), McQuay, York USA), Daikin, Mitsubishi Electric (obania) IDR. Chiller's cost is a cooling capacity of 40kvt- approximately 1-1.6 million rubles.
Country housing systems are most often used with air-cooled chillers with axial fans. The number includes, for example, the model of the AnL series (Aermec), Mini-y (Rhoss), Alfa / HP 81 (Blue Box) and many others. The capacitor is cooled with axial fans. The devices up to 50 kW are mounted on brackets attached to the wall, and more powerful winding onto the roof or on a pedestal under a canopy, located in the yard or in the deaf corner of the garden.

From the chiller evaporator installed on the street, water should be drained to the cold. To do this, it is not necessary to do this, the two-circuit cohesives of cold supply using non-freezing solutions (propylene glycol) as an intermediate coolant. The latter fills the closed circuit connected to the evaporator and laid through the plot and unheated rooms at home. At the same time, the house network, to which fankials are connected, is usually filled with water, and the heat exchange between it and the outer contour is carried out through the heat exchanger mounted in heated technical room.
You can choose a chiller with air cooling capacitor with an axial fan, the evaporator from which is carried out into a separate unit and is installed on the heated area of the house (its connection with the outer unit is carried out with the help of freon pipes and control communications).
In addition, chillers with air cooling with centrifugal fans are often used. They put them in the basement or in an extension to the house (usually similar devices are mounted on vibrooporas to reduce the vibration transmitted to the floor and walls of the house). The air for cooling the capacitor such models are taken from the street, and then return back through the air ducts. Examples of such equipment - equipped with a spiral compressor model YLCC 42-152 (York), unit 30RA 021 (Carrier). To move air, centrifugal fans with high static pressure are used, easily overcoming the resistance of air ducts 5m and more.

26-27. Cyllars with air cooled capacitor CA0100AANB (Haier) (26) and EUWA (Daikin) (27). These models are often mounted on concrete foundations in the garden or in the courtyard of the climate at home, under sheds.

30. Power chiller with air cooled Condenser EUWA40-120KBX (Daikin) can be supplied with cold (or warmed) with water at once several country houses.
The main advantages of apparatus with centrifugal fan is a hidden installation (away from the eye of the neighbors and unintelligible guests), the opportunity to operate the technique all year round in cooling mode at any outdoor temperatures (this mode is in demand, for example, when wine-room coolers and a refrigerator are connected to the chiller ). However, for additional areas under the technical premises for the refrigeration machine and the construction of the Ventsieti will have to pay a considerable amount.
To force the water to circulate from chiller to fan coils and back, you need a hydraulicodula consisting of a circulation pump, an expansion tank, shut-off reinforcement, and control devices and safety. Often, the hydromodule is complemented by a battery tank that allows you to maintain a constant temperature supplied to the fancoal of water regardless of the frequency of stops and the compressor starts. For high-performance systems, the hydromodul is always purchased as separate equipment. Avot in small power devices (usually up to 50-70 kW) It is usually part of their design. Chillers with a hydraulicodul comes to the owner of the house completely ready for use - after installing it, it is necessary to connect pipelines for the heat and colder and tested the power supply.
Involving action
Fan coils (they are also called fan closers) adjust the temperature in the rooms and purify the air from large dust, fluff IT.P. They are manufactured by the same firms that produce chillers. For each kilowatt, the cooling capacity of the Fan Coil will have to pay 10-25 thousand rubles. But we recommend when buying to choose the optimal power to the machine, which will cope with the heat load at the minimum fan speed. This will significantly reduce the noise level in the premises.
For an open installation under the windows most often use floor models of fan coils. They represent a narrow rectangular box, which either relies on the floor, or hanging on the wall. Possible installation of some models of this type and under the ceiling. Floor fan coils are usually white, silver or ivory. However, for example, the Brio Evolution (Rhoss) models can be equipped with a front panel painted in any color according to the RAL catalog, as well as in the branded "grenade metallic", "black graphite" IDR. Extremely elegant modern buildings are different products Omnia HL (Aermec).
Another common version of fan coils for external installation - wall-mounted models (externally difficult to distinguish them from the internal blocks of wall-type split-systems). Mounted them on the interior walls of the premises at an altitude of 2.2-2.5m. If the room has a suspended ceiling (drywall or type "Armstrong"), over which for fan coil there is at least 450-500mm of free space, almost flush with the surface of the ceiling can be installed square or rectangular cassette model in plan. It will evenly distribute cool or heated air in four directions.

But in country houses still use channel models of fan coils, intended for hidden installation (so-called inapproprous models). Such technique is offered by Carrier, Daikin, York Idr. These devices are assembled in a vertical position - under the windows or in the walls, for fake structures from drywall, or horizontal (in the skothil) space. Soclimized rooms, channel fancois are connected by the connecting chambers made of tin or short flexible air ducts, the releases of which are closed with vents that correspond to the color range of the interior. It is to channel models (through the mixing chamber installed at the inlet at the entrance), the fresh air from the supply unit for the ventilation of the rooms is fed.
Internal filling of fanochals, like chillers, is selected for a specific system, taking into account the wishes of the owner of the house. Country housing aggregates are most often equipped with one water heat exchanger (fan coils for two-pipe systems). These devices in parallel are connected to the feed and reverse pipelines, which, depending on the temperature "overboard", circulates cold or hot water depending on the temperature "overboard". You can additionally equip Fancoils with electrotanes, allowing to heat the rooms regardless of the season. Filters are different: in addition to the mesh, passive electrostatic and coal (as an option or as part of the standard configuration) acquire. Aermec also applies ionization filters in fan coils (for example, the FCX P) and bactericidal lamps (FHX).

The cold and heat transfer of fan coils regulate, changing the frequency of rotation of their fans (in most cases such a change is steps) or water consumption, as well as combining these methods (it is the last method that is optimal to ensure comfort). The remote control of the fan coil, as well as its "stuffing", can be selected, based on specific tasks, for example, the simplest or with microprocessor control, providing programming and self-diagnosis of the device. Mounted the console on the fan coil (at floor models) or on the wall. It is possible to equip Fancoils by IR Signal Receivers, and then users will be able to control the climate using portable remote controls.
Surface comfort
When "wet", the method of installation of the pipe in the form of coils is fixed on a flat or curved surface, on which a plaster solution is then applied. APRI "DREE" Mounting (apply only on smooth bases) Use finished panels with already laid inside pipes. Cooling time The water temperature in coils is maintained at about 18C (in order to prevent condensate formation and finishing damage), and when heating the room is about 30-40C.
Only specialists are required to design and mount the Chiller-Fan Coil system. The design and installation organization you entrust this work is obliged to have licenses for all types of work related to the installation of such climate techniques, as well as trained installers. Money is justified to pay only for Equipment with a hygienic certificate and certificate of compliance of the Federal Agency for Technical Regulation and Metrology (Former Gosstandart of the Russian Federation). It is desirable that Chiller and Fanoise are certified by the Eurovent International Organization.
Initial data.
Already after the completion of the construction and finishing of a country house in one of the picturesque villages of the Moscow region, its owners (a young family with two young children) noticed that the possibilities of the heating system for housing is not enough. Brushing summer time in the rooms The temperature kept at the level of 30s even at night, and in cool days when the heating is turned off, the house quickly cooled, and it became uncomfortable. In addition, often the unpleasant smells began to penetrate near the highway in the dwelling, they had to close the windows tightly, which was why there was a lack of fresh air. It was decided to deal with discomfort with the help of equipment for air conditioning and mechanical ventilation.
Decision.
For air-conditioning rooms of a country house, a chiller-funkyla system was selected based on Carrier refrigeration equipment and the Carrier Aquasmart control system. The owner of the dwelling preferred this decision, guided primarily by the principle of the greatest environmental safety (there are no freon pipelines in the premises), as well as due to the simplicity of managing the technique. For the preparation and supply of fresh air to the house, the Carrier ventilation ventilator was used, and to remove the waste air outside the cottage, the Ostberg exhaust fans kit (Sweden). Design, equipment and installation of the climate system in the country house performed the company PRIMA Climate (Russia).
