Сentek split systems: rating of the best offers + recommendations to the buyer

How to choose?

Which air conditioner to choose and what you need to pay attention to first of all? No need to rush, think carefully about your future purchase. It is necessary to take into account many characteristics, type, features of this climate technology

Working mode

Each air conditioner operates in two modes:

1. Cooling is needed to lower the temperature of the air in the room.
2. Ventilation circulates fresh air while maintaining the same temperature.

Air conditioners can produce humidification, but this mode is rare. This function is needed to increase humidity (for example, in winter the air is dried out by heating devices).

Some refrigeration systems operate in both heating and dehumidifying modes.

Mounting

When choosing an air conditioner, it is necessary to take into account how this equipment is mounted in the house:

• Mounting on the wall (at the top under the ceiling) is the most common type of mounting.
• Ceiling mounted between the capital and suspended ceilings.
• Window. Such air conditioners are no longer produced, as they are mounted in a window frame. It is not comfortable. In addition, these air conditioners are noisy.
• The outdoor one is quite powerful and bulky, so they simply put it on the floor.
• The channel is mounted behind a false ceiling or in a wall, so it is not visible.

There are also air conditioners that are transferred from room to room.

Number of blocks

This parameter must be considered when buying split systems. The more blocks, the more powerful the air conditioner. This means that it will cool more than one room.

Power

If the cooling capacity of the air conditioner is less than 2 kW, then it is not a good cooling system. The average power indicator is from 4 to 6 kW, but the characteristics of the most powerful models are in the range of 6-8 kW.

Other Options

When air conditioning is needed for a particular room, then you need to choose it based on its size and the needs of living or working people.

You also need to pay attention to:

• heating and cooling coefficients;
• energy efficiency;
• type of refrigerant;
• built-in filters;
• number of additional features.

Do not rush to buy - consider all the nuances, even the most insignificant.

Expensive or cheap - the differences

Further, when you have decided on the power and type, look at the price, brand and manufacturer. What to choose, cheap or expensive branded model? How do they differ from each other?

Their main difference is the correspondence between the declared and real characteristics. Even in the premium class, everything is thought out to the smallest detail in terms of installation.

The second factor, for which you can sometimes overpay, is lower energy consumption. The so-called class A +++.

Over a long period of time, all this will return to you in the form of smaller electricity bills.

The third advantage of expensive models is the extremely low noise level. Here it does not exceed 20-25 dB. It's like the rustle of leaves outside the window on the quietest day.

The indoor unit of a conventional air conditioner operates within 28 dB. Outdoor from 40 to 50 dB.

These data are valid for models 9000 - 12000 BTU, or the so-called 25, 35s. You must clearly understand that with the increase in productivity, the noise level also invariably increases.

The fourth difference is additional functions. Such as plasma, air ionizer, all kinds of filters, smart eye (redirects the cold stream away from the person).

Whether they are useful and necessary, we will talk separately.

Only if all of the above is really important to you, you can spend money on an overpayment. However, cheaper options, including those in the lower price category, can work well for 5 to 7 years.

Will the plastic turn yellow after a couple of years of operation?

How will they cope with their work on the hottest days and how much electricity do they eat?

In fact, today there are no frankly bad air conditioners. All of them are manufactured in professional factories, often with the same components.

For example, the Chinese brand Gree and the promoted Electrolux install compressors from the same manufacturer in many models.

At the same time, do not forget that when buying even the cheapest copy, you will still pay the standard price for its installation and connection. As well as for all materials.

But the subsequent operation during the declared period of work - cleaning, revision, installation and dismantling, refueling, for inexpensive options, cost even more than the cost of the air conditioner itself. Always keep these expenses in mind and account for them.

Of course, choosing frankly cheap options for less than 15,000 rubles is at least risky.

Their savings primarily come from the lack of such an important component in the production chain as quality control and rejection.

Imagine, you have assembled a full-fledged air conditioner, and then you are forced to throw it away due to the rejection of any part. What do you think, in the end, your product will cost more or less than a similar product from an unscrupulous competitor who does not perform such a check at all?

Therefore, when someone boasts that he bought a Chinese air conditioner for 11,000 rubles and has been using it perfectly for more than 5 years, can such a person be trusted? Of course yes.

He just got a good model. But are you ready to participate in such a lottery? Or is it still better to purchase a product from a manufacturer who is really responsible for compliance with the declared characteristics and their service life? These specific models will be given at the end of the article.

Well, do not forget another important factor - 99% of the successful operation of the air conditioner depends not only on its brand, but on how and by whom it was installed.

Also, when buying, do not be fooled by such a moment as the presence of copper tubes in the kit. Often they come with very thin walls of 0.6mm. Although the recommended value is from 0.8mm and above.

You need to work with such lines very carefully and only if you have an expensive tool (eccentric rolling with a ratchet, torque wrenches). One mistake and the whole job will have to be redone.

Therefore, it is better to buy a more expensive and high-quality block without tubes than to rely on what you slip in the kit in the store

One mistake and the whole job will have to be redone. Therefore, it is better to buy a more expensive and high-quality block without tubes than to rely on what is slipped to you in the kit in the store.

In general, we decided - a good air conditioner starts in the region of 20,000 rubles and more.

Business class technology

Some of the most reliable and high-tech split systems on the market for air conditioning equipment are made by the Japanese. The assembly of this technique is carried out not only in Japan itself, but also in other countries. The most famous brands of Japanese air conditioners, which are classified as business class, are:

• panasonic,
• toshiba,
• Daikin,
• Mitsubishi Electric and Mitsubishi Heavy,
• Fujitsu General.

All of the above items have a high productive capacity, the noise level is the lowest, and the service life is the longest. The term of their service with proper use and regular maintenance varies from 10 to 15 years. These brands of air conditioners are under the manufacturer's warranty for three years. All of them have a modern design, functionality and high energy efficiency.

The most expensive split system and the most prestigious of this category is Daikin. She is considered the number one model among the elite-class equipment. In addition to a compact design and a large set of various functions, this brand is distinguished by the presence of an antibacterial remote control, a motion sensor, and a self-diagnosis function.

Mitsubishi Electric is the model that can be recommended for its good value for money. All air conditioners of this brand are tested within twenty minutes after assembly. The heat pumps built into them are capable of heating up to minus 25 ° C, according to the readings of a wet bulb thermometer.

MitsubishiHeavy air conditioners are not inferior in quality to more expensive models and therefore are very popular. As a rule, they are equipped with high-power compressors, backup switches, an air ionizer, a timer, and have a sleep mode function.

The Panasonic lineup with enviable regularity pleases its customers with updates and improvements in the design of the system. Air conditioners of this brand are distinguished by the presence of a built-in air ionization system, ultrasonic cleaning, auto-switching modes, an oxygen supply system, a self-diagnosis center and an innovative AC-robot auto-cleaning filter system. The disadvantage is that their service is possible only in specialized centers, you will have to dismantle the air conditioner yourself and take it to a service center.

The most pleasant and useful feature of business-class equipment is the presence of an excellent system of protection against misuse.

Equipment Selection Tips

The right choice of climatic equipment will depend not only on the model of the split system, but also on other parameters.

Here are just the main parameters that you need to focus on when choosing:

• placement method;
• the possibility of smooth adjustment;
• What area of ​​the room is the system designed for?
• presence and quantity of heat sources.

Each parameter is significant, so they need to be considered in more detail.

In order for the split system to please the residents and guests of the premises, it is necessary to pay enough attention to the correct choice of equipment. The wrong wattage or system type can reduce the efficiency of appliances in your home.

According to the method of placement, modern split systems are divided into wall, channel, floor-ceiling, window, cassette units and mobile air conditioners. All listed types of climate control equipment have their advantages and disadvantages, which should be studied before buying.

It is worth noting that wall-mounted equipment is considered the most popular solution for housing. It takes up little living space and is easy to manage. In addition, maintenance of splits does not cause any particular difficulties.

Adjustment of split systems can be inverter and discrete. The first method prevails in modern designs. Inverter temperature control is smooth, users themselves choose the air temperature that is comfortable for themselves. Discrete adjustment is carried out in certain intervals.

The service area is one of the determining parameters when calculating the power of the air conditioner. Low-performance equipment will not work effectively in large rooms. The air temperature will change very slowly and mainly in the area of ​​the equipment.

It is not advisable to buy an air conditioner that is too efficient for small rooms, since a significant part of its power will not be consumed.

Do not forget about the timely maintenance of split systems. This applies to cleaning and replacing filters, maintaining the main structural elements and checking the freon level.

Additional space heating can significantly affect the efficiency of using a particular model of climate technology. This is due to the fact that on a sunny day, the power of the device may not be enough to maintain a stable temperature inside the room. The same applies to cases when there are a lot of people in the room.

Therefore, you need to choose equipment with a power reserve. For example, 1 kW of air conditioner power is enough to serve 10 m2 of area. If the area of ​​a room or office is 20 m2, then the calculated power of the climate equipment will be 2 kW.

It is recommended to take split systems more powerful by 10-20% of this value - at least 2.2 kW.

Buyers will have a difficult choice of split systems from the assortment offered by sellers. You should carefully study the technical documentation and recommendations of the equipment manufacturer

Instructions for use

Note that for models of various series, the company has created a single instruction describing all technical characteristics, safety measures, various components, as well as rules air conditioning care. Thanks to the detailed manual that comes with each model of air conditioners, life-threatening situations can be avoided. All manuals are written in a simple language that will be understandable even to a person who has not previously used such a device.

It should be remembered that according to the instructions it is forbidden to wash the module itself or the remote control or its buttons under running water. In addition, materials such as gasoline, alcohol, various kinds of abrasives and hot water with a temperature of more than 45 degrees cannot be used to maintain plastic so that it does not deform and lose color. When installing a split system, the difference in levels between the blocks should not be more than 5 meters. In order to reduce energy costs, as well as to minimize the possibility of condensate accumulation on the surface of the inter-unit route, which will significantly reduce the operating time of the connection nodes, experts propose to carry out the insulation of the communication route.

For carrying out thermal insulation of tubes made of copper, a rubber-based thermoflex is usually used.The connecting line, which consists of a pair of insulated pipelines, an electrical cable and a drainage pipe, is tied with Teflon or bandage tape. Due to the large number of materials for track insulation, there are no difficulties in finding them. The piping of the split communications is carried out as carefully as possible in order to prevent damage to the copper tubes. It is better to entrust this work to specialists.

If we talk about working with the indoor module, then it should be said that in no case should you turn on the split system again during the dehumidification until it is completely finished. Another important point that should not be neglected in any case is not to use a smartphone or mobile phone near the internal module due to the fact that interference from it can cause malfunctions in device control. But if for some reason a failure did occur, the manufacturer recommends rebooting the device by turning off the air conditioner from the network.

What are air conditioners?

When deciding which air conditioner to choose for an apartment, you should find out what types of these devices exist.

Air conditioners are presented:

1. split systems. The most common among household devices. Equipped with two blocks: internal and external. They make almost no noise, are controlled by a remote control, are equipped with a display, have fine tuning, temperature mode setting and other advantages.

2. Wall-mounted split systems are designed for rooms with an area of ​​15 to 90 sq.m. This is a very good air conditioner for an apartment.
3. multi-split systems. This is an improved modification of the previous system, but with several additional blocks.If each room needs its own temperature, a multi-split system will be a good solution. This type of equipment is difficult to install, so in order to mount it, you should read the instruction manual and instructions.
4. mobile. These devices do not need special installation, but are used only in small rooms due to their low power. Mobile air conditioners for an apartment are very cumbersome to move and have a lot of noise. The reviews of people who have bought these mobile devices are mostly good. Installing a mobile air conditioner is not difficult, for this you should not turn to professionals.
5. channel. Install these units only in ventilation ducts. These devices are not particularly popular, as they are difficult to install, maintain and rather expensive. The main advantage of the equipment is stealth.
6. window. Attached to the inside of the window. Inexpensive and easy to install, but it also has some disadvantages. The units are too massive and are located on almost the entire window. In case of poor sealing of the opening where the apparatus is located, cold air passes into the apartment. Also a bit annoying is a little noise from the system.
7. console. Systems of this type are installed both on the walls and on the ceiling. Such air conditioners practically do not have any differences from split systems. However, they make it possible to choose the installation location - on the ceiling or wall.
8. ceiling. They take up little space due to their small size and narrowness. Installation of these devices is only possible on the ceiling.
9. cassette. Convenient devices installed in a false ceiling. They provide the direction of cold and hot air throughout the apartment.Therefore, heating and cooling in the room will be of very high quality.

4 HISENSE

The Chinese company HISENSE was founded in 1969, starting with radio receivers. Perhaps the difficulties in the development and production of small equipment had a positive effect on the further development of the company that creates air conditioners. In the bowels of the enterprise, China's first inverter-controlled cooling system was born. At present, HISENSE maintains a leading position in the global market, selling its products to 130 countries.

A distinctive feature of Chinese split systems is rich functionality and stylish design. The manufacturer has developed several lines of air conditioners for apartments and houses, for offices and industrial premises. Users speak flatteringly about such qualities as power, quick heating or cooling, unique air purification, excellent quality. It does not cause trouble for technicians to installers and servicemen. The only downside is the sticky stickers.

Power and space

To determine the performance of an air conditioner, you can use complex formulas that take into account the number of windows, the number of people in the room, the sunny or shady side of the room.

But it is much easier to navigate by the area of ​​\u200b\u200bthe room.

All household air conditioners by power can be divided into 4 types:

low-power up to 2.5 kW

average power up to 3.5 kW

high power up to 4.5kw

maximum power over 4.5 kW

There is no point in overpaying for the device to work at half strength. In small rooms - nurseries, bedrooms, kitchens up to 20m2, low-power models up to 2.5 kW are suitable.

Here the calculation is very simple. For every 10 m2 with a ceiling height of up to 3 meters, at least 1 kW of cooling capacity is required. If you have a sunny side, then 1.5 kW.
Start from these data, substituting your quadrature.

Most often, when mentioning performance, sellers simply say 7-ka, 9-ka, 12-shka. What does it mean?

This refers to British thermal units BTU. For them, the formula 1BTU \u003d 0.3W applies.

Types and principles of operation of air conditioners

The main task of the air conditioner is to cool the atmosphere of the room, other functions are designed to create additional favorable conditions.

The floor monoblock works on the principle of evaporation

Monoblock (from one module). All elements are in a single housing. By location, window, wall and mobile air conditioners are distinguished. window worked on the principle of evaporation, they were installed in the opening of the window. With the advent of plastic windows, this equipment was no longer used.

Wall monoblock refers to the compression type: it consists of an evaporator and an air blower. For installation, two holes are required to be punched outward - for the inflow of fresh air and the removal of hot air from the condenser.

Mobile or floor standing Compression air conditioners and coolers work on the principle of evaporation. Installation is not required: the heated air outlet sleeve is directed to the window or hole in the wall.

Split systems according to the mode of action compression. Divided into 2 modules interconnected by an electric cable and tubes for refrigerant overflow. The external unit serves to discharge heat to the street, it is placed on the outside of the wall. It has a freon cooling condenser, a fan and a compressor.The interior of the split system can be wall, floor, ceiling and mobile - the first option is in greatest demand.

The functionality of the air conditioner allows you to cool and heat the air, clean it from dust and outdoor gases, maintain humidity within the established range. The structure is controlled by a remote control.

Cold evaporation

Principle of operation:

• air enters through the cartridge;
• heat from the incoming flow is directed to the working grids;
• drops of water evaporate from the heated element, the temperature drops, the air becomes cold at the outlet of the air conditioner.

Compressive temperature reduction

The principle of temperature reduction is identical to the processes occurring in the refrigerator. Main elements: compressor, condenser, evaporator.

The whole system works in a closed mode - freon circulates through copper or aluminum tubes between the functional parts, which transfers heat from the room air to the outside. The principle is based on the property of a liquid refrigerant to boil and turn into a gas at a temperature of 10–20ºС, depending on the pressure in the system.

Principle of operation:

• the evaporator is under low pressure, freon is transferred from the liquid phase to the gaseous state and takes heat from the incoming air stream;
• the heated refrigerant vapor enters the compressor through the tubes, pressure is pumped, due to which the boiling point of freon rises, the gas passes into the initial liquid state;
• the evaporator receives the condensed heat carrier of the second circle, hot air is pumped through the fan to the outside.

How to install yourself in a private house?

Installation of a split system is carried out according to the instructions attached to it.Most often, the algorithm of actions is quite simple, so you do not need to call specialists for installation. Correct and high-quality work is performed in the following order:

• Installing the indoor unit.
• Preparation of communication channels.
• Laying in the channels of the connecting line.
• Installing the outdoor unit.
• Connection of the system with highways (gas and electric).
• Vacuum and leak test.
• Filling with refrigerant (freon).

Any installation work requires strict adherence to safety regulations and the installation of a split system is no exception. In this case, speed is not important, but quality. Since subsequently the discrepancy between the installation standards will negatively affect the operation of the device.
