Review of DAIKIN air conditioners, instructions for them and user reviews

The Japanese company DAIKIN, engaged in the production of climatic technology and heating equipment, is taking a leading position among other manufacturers of this product sector. Why are DAIKIN air conditioners recognized as the best, for what technical characteristics and additional options?

Why DAIKIN: 3 reasons

Firstly, this company subdivides all equipment into household, commercial and industrial.

The household section mainly includes split and multi-split systems, which, thanks to the new introduced technologies, optimize the living conditions in apartments, residential buildings or in small offices and shops to the maximum.

Commercial equipment is represented by a very wide range of technical solutions for restaurants, hotels, banks, sports facilities and similar organizations. These include chillers, fan coil units, VRV systems and the SKY-AIR class of air conditioners with wall, duct, cassette and under-ceiling types of indoor units.

DAIKIN industrial air conditioners include such equipment as VRV with inverter control, modular systems with the ability to integrate an air conditioner, industrial condensers, precision air conditioners, chillers and other high-performance configurations. They are used in various industries and agriculture, where technological objects of cooling / heating have large areas and complex architectural solutions, and also require the correct organization of the microclimate to maintain the "life" of production facilities and compensate for significant heat surpluses.

Secondly, many manufacturers do not have those additional options that DAIKIN offers. For example, its new splits feature the unique Ururu Sarara air handling system, which humidifies without additional water supply and dehumidifies without cooling, which makes the room climate comfortable at any given temperature. Basically, it is an air conditioner with a built-in humidifier and air purifier.

Thirdly, this Japanese manufacturer has a whole series of only outdoor units of DAIKIN air conditioners or only indoor ones. This is due to the fact that the device of this climatic technology is very "flexible", so they can be combined with each other from different series. This fact significantly expands the boundaries of consumer choice and gives more opportunities in the design of objects.

Types of DAIKIN air conditioners

The range of offers is worthy: splits with different types of indoor units, so-called "cartoons", VRV with the ability to connect up to 20 indoor units, fan coil units, chillers, rooftop air conditioners and other types of air conditioning systems.

This article discusses the most popular and demanded DAIKIN air conditioners that can be bought in Russia.

DAIKIN wall systems

Splits with a wall-mounted indoor unit are distinguished by their non-trivial design. Aesthetic contours and lines, in line with the trends of modern style directions, are embodied in a curved panel. Original colors, compact shapes, wide flaps - all these qualities are possessed by the split systems of the EMURA, SKY INVERTER, URURA SARARA series.

This wall-mounted equipment belongs to the premium class, so the optional saturation and technical characteristics of DAIKIN wall-mounted air conditioners are impressive:

• high performance combined with reasonable energy efficiency due to the rotary compressor for most models and energy saving features - auto filter cleaning and 2-zone presence detector;
• new safe refrigerant R32;
• extended operating temperature range;
• noise level up to a maximum of 19 dBa;
• double air intake and volumetric air flows;
• 5 ways of air handling - humidification, dehumidification, ventilation, purification, heating / cooling;
• online controller to control the air conditioner via the Internet or telephone.

Minimal energy consumption, excellent performance and reduced carbon dioxide emissions - that's what the standard wall split from DAIKIN gives.

Cassette systems DAIKIN

The external unit of the DAIKIN cassette air conditioner is located outside, and the internal unit with all communications is masked under a suspended or false ceiling. Only the decorative distribution grille, fixed in a single plane along the ceiling line, remains in the viewing area. It is the ideal solution for rooms from 40 m² to 150 m², as well as where strict savings in usable space are required when connecting.

DAIKIN semi-industrial (SKY class) cassette air conditioners, for example, of the FHYC, FCQ, FFQ and FHYK series, are in good demand among buyers, as they provide excellent technical performance and have a number of convenient options. And this:

• power, which makes it possible to quickly reach the set air parameters;
• low noise level;
• antibacterial surface of the remote control;
• the ability to combine them into Twin, Triple or Double Twin systems;
• automatic mode selection and restart;
• protection against extreme temperatures;
• fresh air admixture;
• powerful filtration system;
• obligatory condensate drainage;
• economical night mode;
• self-diagnosis function in case of malfunctions;
• function of accounting for weather conditions;
• no contamination of the ceiling due to a special dampers movement algorithm.

Many buyers unanimously believe that DAIKIN cassette air conditioners are a stylish climate technology that optimizes the conditions for people in various public areas, as well as fully controlled settings to create comfort.

Ceiling systems DAIKIN

An ideal room for a DAIKIN ceiling air conditioner should have an area of ​​up to 150 m² and a ceiling height of up to 4 m. Such structures are placed as follows: the device itself is fixed to the ceiling, and communications are masked. This is also a SKY class technique.

Typically, DAIKIN under-ceiling air conditioners are available with 1, 2, 3 or 4-way indoor unit. The choice of the number of streams depends on the shape of the room and the location of the device itself. The FHY and FHQ series distribute air in one direction, while the FUY and FUQ distribute air in two, three or four directions. First, air masses are taken through the grille in the front panel, and then along the ceiling they go into the room. In order for the flap to swing in the desired direction, it is necessary to set the ceiling height to it with the remote control.

In addition, DAIKIN ceiling air conditioners have other advantages:

• inverter technology that reduces noise and increases energy savings;
• oxygen admixture;
• efficient air distribution vertically and horizontally;
• automatic maintenance of the permissible humidity level;
• anti-mold treatment of the filter;
• an economical mode of operation in the absence of people in the room with a quick return to recreate comfortable conditions when they appear;
• protection of the heat exchanger of the outdoor unit from frost;
• rise of condensate by means of a drainage pump.

Ceiling air conditioning systems can also operate in multi-split and VRV systems as part of them.

This is an ideal environmentally friendly working atmosphere and efficient energy saving for years to come.

DAIKIN channel systems

With the help of DAIKIN duct air conditioners it is possible to cool huge areas (up to 250 m²) of one or several rooms. In this case, only one external unit is required, to which several internal ones are connected. The latter are sewn under the final ceiling or wall, making the installation completely invisible.

Channels are supplied to the external block through which cold air enters, they are thermally insulated (to prevent the formation of condensation) and soundproofed. This type has the ability to mix fresh air through an extensive network of air ducts - up to 30% of the total volume of air masses.

DAIKIN air conditioners with a ducted indoor unit are divided into 3 categories:

• low-pressure - with pressures up to 40 Pa, small rooms with high noise requirements are treated (FDX series);
• medium pressure - with a pressure of up to 100 Pa, larger rooms are treated, have a noise level of up to 29 dBa due to aerodynamic noise in the channel (FBQ series);
• high-pressure - with pressure up to 250 Pa, power up to 26 kW in heating mode and long duct length (FDQ series).

All categories maintain the microclimate in two ways: by observing precisely set parameters in the local area or by reaching approximately common values ​​throughout the room. In addition, ducted air conditioners have a number of additional advantages:

• noise reduction mode for both units;
• electronic power control;
• swinging rotor for contact with harmless refrigerant;
• anti-mold filter;
• automatic control of normal air humidity;
• functions of self-diagnosis, night saving and absence / presence of people in the room;
• anti-corrosion treatment of materials.

These are far from all the technical characteristics and functions of DAIKIN duct-type air conditioners. Each series and model may have additional features. But a special plus is the layout of the multisystem, which reduces the number of outdoor devices, preserving the appearance of the building and saves space, since it is not always possible to place several outdoor units.

It is necessary to accurately calculate the length of the route so that the freon normally reaches the indoor unit, correctly design the system in order to avoid excessive air supply through some air ducts and insufficient through others. You also need to thoroughly fix the air ducts and select high-quality material for them, otherwise expensive equipment will emit extraneous noise.

Industrial systems DAIKIN

The most important distinguishing feature of DAIKIN industrial air conditioners is their power, the values ​​of which start from 7 kW and reach enormous values. Such equipment is installed in institutions with a large area and having strict requirements regarding the maintained air parameters - medical laboratories, server rooms, warehouses, banks, and so on.

At DAIKIN, all industrial air conditioners perfectly keep the set temperature, humidity level and make it possible to make pre-settings. The model range includes rooftop air conditioners (UATYQ-C series), screw (EWAD-TZ series) daikin inverter air conditioners (EWAD-AJYNN / S series), cabinet units (UCPJ series) operating only for cooling, but with excellent cooling capacity up to 189 kW, multi-zone VRV and VRF systems and other high-tech equipment.

By the way, rooftop monoblocks are an inexpensive option for large premises such as shopping centers and department stores. Another plus is the simple installation, carried out on the roof or next to the building itself. It provides energy savings with free cooling during the transitional seasons - the outside air is used to cool the inside, and this saves electricity consumption.

DAIKIN precision systems

When it comes to maintaining the temperature in the server room (data center), DAIKIN air conditioners can be converted to precision. They are installed where it is important to create conditions with an accuracy of tenths of a degree and a deviation in humidity marks of not more than 2.5%, as well as regulate the content of harmful microparticles in the air during a continuous production process.

All DAIKIN precision air conditioners are divided into devices:

• air-cooled heat carrier - consist of an indoor unit with the main units of the device, and an outdoor (remote) unit installed outside the premises;
• water-cooled heat carrier - consist of one unit with a water condenser located inside, the heating mode is carried out by a built-in electric heater, and not a heat pump;
• with mixed cooling of the heat carrier - has 2 circuits: freon and water, the principle of operation of which is to transfer heat from the first to the second, and in turn, the water, through an external heat exchanger, removes excess heat.

The first two types are single-circuit, in contrast to the last.

In some series, DAIKIN rooftop air conditioners are equipped with a "Free Cooling" control system, which, when the outdoor temperature drops, uses its cold streams supplied through the air ducts for internal cooling. This saves energy consumption significantly.

A precision air conditioner DAIKIN for a server room can have different ways of air supply: upper and lower. In the first version, the transmission goes through the air conditioner itself and the ceiling ducts, and in the second - through the air distributors from the raised floor.

The additional advantages of air conditioners for the server room from the DAIKIN company, judging by the reviews, include:

• fan power, which exceeds the standard values ​​by three times;
• a huge range of working t ° - from -45 ° to + 50 ° on the street (for other industrial ones, the limit is -15 °);
• high cold performance, reaching 300 kW in some models;
• support of precise set parameters by the built-in microprocessor;
• round-the-clock and year-round uninterrupted operation of the system.

All industrial climatic systems from DAIKIN are distinguished by long-term operation without breakdowns. But at the same time, several conditions must be observed: accurate design taking into account all the features of the building, installation only by experienced specialists and regular maintenance.

When designing in case of equipment failure, it is necessary to provide for at least 50% redundancy and an immediate notification system of failures in operation.

Outdoor and indoor units for multi-split systems and VRV systems

As mentioned earlier, DAIKIN produces separate series of outdoor and indoor units, which can have different layout options among themselves in multi- and VRV systems.

An example is the Super Multi Plus system, which is designed for installation in cottages, large apartments, salons, that is, where there is a small group of rooms. The external units of the DAIKIN air conditioner from this series have a cold capacity from 11.2 kW to 15.5 kW and are combined with the Split and SkyAir class indoor units. At the same time, the external block of such a DAIKIN air conditioner can be combined with 9 internal ones in one system.

There are also a number of different types of indoor units that are suitable for working with outdoor units in the MXS multi system.

This expands the boundaries of the choice of equipment, and also makes it possible to solve complex technical problems.

Instructions for DAIKIN remotes

Like all other manufacturers, DAIKIN has operating instructions for all series and models of air conditioners. They include a standard set of operating recommendations, descriptions of performance and additional options, installation tips and, of course, detailed instructions for the DAIKIN air conditioner control panel with all the rules for setting various modes.

We can say that the last point is one of the most important, since there are detailed settings for setting the main modes of cooling, heating, dehumidification, ventilation and purification. The manual for the DAIKIN air conditioner control panel explains how to turn on the “Timer” function, how to adjust the air flow or turn on the economy mode.

The basic instructions for DAIKIN air conditioners also contain important information about failure cases that are not malfunctions. For example, if the operation suddenly stops and the "Operation" light comes on, this means that the protective stop of the device operation is triggered in case of significant voltage fluctuations. It usually resumes after 3 minutes.

DAIKIN air conditioner error codes

Also, the manual for the DAIKIN air conditioner remote control has important information about fault codes that require an immediate contact with the service department. In another way, they are called error codes for DAIKIN air conditioners, which are divided into errors:

• systems;
• indoor unit;
• outdoor unit.

All errors of DAIKIN air conditioners have their own alphanumeric designation, that is, a code. For example, consoles for daikin air conditioners or panels of the FTK20GV1B model showing an error U0 indicate a lack of refrigerant.

When buying, you should immediately check the complete set of the purchased equipment and the availability of instructions as well.

Customer reviews about DAIKIN

In almost 100% of cases, reviews of DAIKIN air conditioners contain only positive reviews from both buyers and service centers.

Of course, the price of HVAC equipment from this manufacturer is higher than that of other manufacturers, but the quality of the equipment purchased justifies this. Here are the main characteristics that users give in their reviews of DAIKIN air conditioners, both industrial and household:

• chic design of any models of split systems;
• quiet operation of both units;
• reliability and durability of operation;
• multifunctionality;
• high energy efficiency class in most series;
• thoughtful direction of air flows → no colds;
• inflow of fresh air;
• built-in humidifier and air purifier.

By the way, for those who have children, systems with the "smart eye" function, which diverts the air flow from a person, are simply irreplaceable.

DAIKIN is real climate control. The system will not break down in two or three months and is unlikely to interfere with neighbors with its noise, so the reviews about these air conditioners are fully justified and proven by a practical method.

The main thing is to entrust the installation of equipment to competent specialists, so that later you can enjoy full-fledged comfort on hot summer days and chilly autumn-spring off-seasons.
