Advantages and differences of the inverter air conditioner

What is an inverter type air conditioner? On the appearance of such climatic devices are no different from their own kind. External assembly is also typical for representatives of such devices. You can say the same about functions. But at the same time the inverter type air conditioner is considered a more advanced device with stable operation. An analysis of the possibilities of the inverter technology will help to understand whether this is true or a publicity stunt.

Principle of operation

What are the differences between the usual conditioners and our heroes? And what is an inverter split system? Which air conditioner is better - inverter or normal? Is there a risk to overpay? These and other questions arise in the head of the future owner of climate technology.And you can answer them only by analyzing the differences between the inverter air conditioner and its usual counterpart.

Normal air conditioning

A typical appliance should regulate the temperature in a room based on on the temperature sensor readings - The last user exposes. The bottom line is that when you exceed this indicator, the device simply turns off. Naturally, after some time the temperature begins to rise, so there is a re-start, during which the normal air conditioner starts to work at full capacity. Thus, the technique works all the specified time.

These on-off have not the best consequences:

• peak load on the device at the time of launch;
• a jump in the power grid (increased energy consumption);
• wear parts of the mechanism.

It turns out that the non-inverter device works cyclically. And in order for its engine to accelerate, large starting currents are consumed. After the start has occurred, the compressor starts pumping 50% of the total volume from the freon from the low to high pressure zone. At the same time all systems are involved to the maximum.

How is the pressure normalized after the compressor is turned off? The throttle system is responsible for this. But in any part of the system remains freon boil risk (can occur in the line, in the receiver, and in the capillary tube). And the unused potential cold comes out, irrationally cooling the air outside. Of course, there is compensation, but it is small - at the same time the cold is produced in the room. To some extent this equalizes the loss when the compressor starts up again.

Inverter model

The air conditioner with an inverter is different than with conventional models. Here, the control unit converts alternating current into direct current, and then converts it back to alternating, but already current frequency.

The knowledge of physics will help answer the question of what constitutes an inverter in an air conditioner. It turns out that the inverter is aimed at raising and lowering the usual frequency of the network. This inverter power control air conditioner and formed the basis for the name of the device. It influenced engine speed change compressor, and, therefore, on its performance.

The principle of operation of the inverter air conditioner is as follows. The device has a thermostat, provided as a standard temperature meter, but when it reaches the desired level, it does not turn off, but simply reduces the power at work (leaving only 5-10% of the usual).The temperature in this case will fall much slower, but when the permissible threshold is passed, the compressor will start again. Inverter compressor operates in the range of 1-1.5 degrees (compared to conventional, in which such data range from 1 to 5 ° C). At the same time there will be no absolute load on the device.

The scheme of the inverter air conditioner includes the usual external and internal blocks.

1. Elements such as a compressor are located in the outer part, followed by a system filter with freon, followed by a fan to cool the freon and a condenser. Also worth mentioning is the control board and connections.
2. Now about the indoor unit: the first thing to mention is the evaporator for cooling the air, the fan, the louvre parts, as well as the filter and the sump into which the condensate flows.

Pros and cons of using inverter systems

Having understood what the name of the model “inverter split system” means, it's time to talk about the pros and cons of the units. At first about bonuses - even after a short period of use, users have time to appreciate the benefits of this technique.

1. The difference between the inverter air conditioner and the usual one isthat it has no restrictions in work (for a traditional device it is not more than 8 hours per day).
2. Do not worry about network overload. And their absence is already power savings in the range of 30 to 50%. When paying utility bills, the difference is significant.
3. The device can be called economical - there are no “idle loads”.
4. There is an exact maintenance of the set temperature.
5. The impact of the air flow also becomes more comfortable: during conditioning, a gentle flow of 12-15 ° C will come out. This reduces the likelihood of getting sick (as is the case when using an ordinary analogue).
6. Reduced noise level (only 19-23 dB) allows to operate such a device even at night (in comparison, in the usual version it is 30-32 dB).
7. Long service.
8. Finally, a device with an inverter will help to heat the room even at a temperature of up to - 25 degrees.

There are certain disadvantages of inverter air conditioners.

1. "Raisin" in the form of soft thermoregulation is not suitable for every room. What is ideal for bedrooms and children's rooms, absolutely can not cope with the creation of a comfortable atmosphere in offices and other public places (people constantly enter and exit, close and open windows).
2. You should not put the inverter air conditioner in the kitchen, its work will break the heat from the kettle or stove. Climate technology simply can not cope with such constant changes in temperature.
3. Not the last word for the maintainability of devices. For example, the varieties of inverter and non-inverter compressors are exactly the same, but if the electronic board fails, then its replacement will cost at least 10,000 rubles. And spare parts can not be found in the general sale.
4. For economic reasons, it is unprofitable to operate such a unit in the country, which is rarely visited by residents.
5. Finally, high price the device makes it problematic for anyone to purchase it.

Choosing the best model

Today, the split-system of the presented inverter type is a product of the development of almost all manufacturers, specializing in the production of climate technology. Among them are such names as Daikin, Toshiba, Panasonic, Mitsubishi and many others. Each brand has its own advantages and disadvantages.

Daikin According to user reviews, they are the most popular climatic devices. They work on safe freon, and they are ready to fulfill their mission even in the conditions of a severe winter. There are two product lines on the market - FTX and FTXN.Both have excellent economic and ergonomic indicators, a long service life, there are floor and wall inverter air conditioners. Another bonus is the declared low noise (in top models it may even be 19 dB, however, most buyers still object that the noise still appears at elevated speeds).

People's love and models stamps Lg. It attracts low wear and the ability to choose a variety of temperature conditions without a load of the power grid. The unit can work at very low revs. The characteristics of this brand are marked by a rather high power level. But there are also disadvantages: the equipment is very sensitive and can not withstand large voltage surges.

It is very expensive as the technique itself, and components on it.

Panasonic produces high-quality and affordable devices. Products of this brand are distinguished by the use of a pulsed-type unit - this means that they are less susceptible to power surges. Many of the models are great for office space. They are also good for the home, as they have a night heating mode.

Now about BEKO - a brand that shows what an inverter split-system is in all its beauty: ease of control is combined with high power (a more advanced unit is used). The model has a dehumidification mode and there is even a built-in air ionizer.

About any inverter split from Electrolux speak as about the universal and qualitative good device. Positive ratings he earns, first of all, good management. However, the model also uses special anti-icing protection.

Inverter from the brand Toshiba You can cool a room of 30 square meters. meters There is a built-in pulse unit that protects the system from power surges. Energy efficiency will not exceed the figure of 80%. Split systems of this brand with inverter control - one of the most affordable.

By the way, Toshiba was the first to introduce such devices.

There is another mentionable brand - COOPER & HUNTER. Unlike other models, the units have a transforming power unit. The advantages of this inverter air conditioner are also in excellent speed control.

Tips for buying any of these devices

To choose the right split-system with inverter control, you need to listen to the following recommendations.

1. If the budget is limited, it is better not to buy the cheapest of the available inverter models. Let it be better the usual split, but from a well-known manufacturer and having a good reputation.
2. It is better to choose a model with large capacityespecially if you plan to install it in a bedroom or baby room. Such a device will work without noise and draft.
3. Installation of the system should be entrusted only to professionals. According to the service centers, 80% of all failures are caused by illiterate installation.
4. It is best to carry out the installation in the spring, and not in the "hot season", when it is full of suggestions from incompetent specialists.

Maintenance work

Even a super modern air conditioner can fail without proper care. It is important to know that split-systems with inverter control require compliance with certain rules for their care.

1. Do not allow liquid to enter the refrigerant circuit. This is fraught with the formation of acid, which corrodes the insulation of the engine.
2. Actually constantly monitor the level of oil and refrigerant used.Freon will drop - and the pressure in the system will drop, and, therefore, the device will start working for wear.
3. Important and regular cleaning the heat exchangerAfter all, the accumulation of dirt is a direct path to its overheating, increase in pressure and load.

Ignoring such recommendations may cause damage to the device.

Information about what an inverter split-technology, allows in all the beauty to understand the prospects for its use. But is it worth overpaying for its purchase? The answer will be this: with a small budget it is better to opt for conventional air conditioners, but of the highest class. Actual availability of service centers where they can provide qualified assistance.

Air conditioners of this type can be recommended for installation in apartments - residents will appreciate the "soft" cold and quiet operation. But if there are constant surges of electricity in the house, it is better to refuse such a purchase. And one more thing: you shouldn't think that the device will quickly pay for itself due to its energy-saving consumption. According to specialists, this period should be at least 5 years - during this time no equipment is insured against breakdowns and overloads.
