In recent years, new types of air conditioners, inverter ones, began to appear in household appliance stores. Sellers offer potential buyers to opt for them: according to the assurances of workers in retail chains, they are much better, but in many cases sellers cannot answer the questions: what does inverter air conditioning mean, what exactly is the difference between an inverter air conditioner and a conventional one? Let’s take a closer look at the difference between inverter and conventional split systems..

What is an invertor split system

Like any other split system, this type of climatic equipment consists of an outdoor and indoor unit. In the outdoor unit there is a compressor, a freon system filter, a condenser and a fan that cool the freon, and a control board and fitting connections. In the indoor unit there is an evaporator with which air is cooled, a fan, horizontal and vertical blinds, a filter and a condensate pan.

What is the difference between an inverter air conditioner and a conventional

The main structural difference of this modification of wall-mounted climate systems is mainly the presence in the outdoor unit of a control board that regulates the operation of the unit so that it turns on and off much less often. The usual split system works according to the following principle: after the room temperature rises by 3-5 degrees, it turns on, and after the device cools the temperature to the set limits, the device turns off completely. Next, the on / off cycle is repeated.

The principle of operation of the inverter air conditioner is somewhat different. After the first inclusion, the split system will cool the room to the required temperature, but immediately after that it will not turn off, but will continue its work, but already with a reduced power by 25-75% (sometimes by 5-90%). This is achieved through the use of an inverter in the design of the unit. What does inverter mean? This means that the unit is equipped with an inverter – a device that can smoothly change the power of the device.

Upon reaching a predetermined temperature mode, the speed of the unit is reduced, it continues to work at reduced power, which is enough to maintain the desired temperature. Most budget inverter split systems are still completely turned off, but much less often than ordinary models of air coolers. Only expensive units, the power of which varies from 5 to 90%, can almost never turn off.

According to the passport data, conventional split systems are not designed for continuous operation, from time to time it needs to be turned off. Such units in heating mode operate at an ambient temperature of at least minus 5 degrees. Unlike conventional air coolers, units with an inverter are adapted for round-the-clock operation, they are able to work in heating mode at street temperature up to minus 25 degrees.

Advantages and disadvantages of inverter technology

The main advantage of this technology is the smooth temperature control in the living room. Split systems with an inverter are able to accurately maintain the set temperature parameters, temperature fluctuations in the room are only 1-3 degrees, which provides maximum comfort for people in the living room. The usual split system in hot weather has to be adjusted to maintain 18-20 degrees.

Turning on, the indoor unit of such an unit begins to create a sharp and cold stream of air, creating discomfort. Any person under the influence of this airflow risks catching a cold. Upon reaching the set parameters, the air cooler is turned off, and the next time it turns on only when the room becomes hot again. The split system with an inverter does not turn off when the desired parameters are reached, it maintains the set temperature with an unsharp air flow, eliminating the main drawback of conventional air conditioners.

Benefits

• Exact maintenance of the set temperature condition.
• Work around the clock.
• Work for heating at a temperature in the street from -10 to -25 degrees.
• Economical energy consumption.
• Extended service life.
• Low noise.

disadvantages

• 30-40% increased cost.
• The dependence of the control board on voltage drops.
• High repair cost.

Which inverter driven air conditioner is better

Many brands produce this category of domestic climate systems. The highest quality products are considered Japanese brands – Daikin, Toshiba, Panasonic, Mitsubishi and others. These manufacturers are constantly improving the design of their products, which are becoming more sophisticated: more economical and less noisy. Most models of Japanese manufacturers are able to change performance in the range from 25 to 75%, and top models from 5 to 95%.

Korean companies produce good air conditioners with inverter drive, the quality of a little inferior to the famous Japanese brands. Compared to Japanese counterparts, Korean appliances are not much worse, but they are slightly cheaper. Chinese manufacturers produce low-cost split systems with an inverter, but they are able to reduce their own power only in the range from 35 to 70%, which is noticeably worse than that of units manufactured by Japanese and Korean brands.

Invertor split systems Daikin

The Japanese company Daikin specializes exclusively in the production of HVAC equipment. All products manufactured at the company’s factories undergo mandatory testing. Units manufactured by Daikin are distinguished by a long service life (both wall and floor modifications), low noise (22-27 dB, on top models – 19 dB), excellent ergonomics and economy, the presence of many functions, including a self-diagnosis function. 2 lines are popular – FTX and FTXN.

Mitsubishi electric

In terms of price / quality ratio, Mitsubishi Electric air conditioners are unrivaled. The manufacture and assembly of units and assemblies is performed using modern technologies. Each assembled air cooler goes through a 20-minute test, and some products go through a deep spot test. Some modifications of split-systems of this brand are adapted to work on heating at an external temperature of minus 10 to 25 degrees. The company manufactures products with an inverter of the MCZ-GE and MSZ-HJ series, which have minor differences.

Toshiba

The Toshiba company is engaged in the production of split systems of all modifications, including an inverter. Products of this company compares favorably with products of other Japanese brands in terms of price: it is slightly lower than that of Panasonic, Mitsubishi and Daikin air coolers, and the quality is not worse than theirs. The company produces several lines of inverter air conditioners – SKV, PKVP (with an increased long track), SKVP-ND (adapted for operation at outdoor temperatures up to minus 10 degrees).

Fujitsu

Split systems with an inverter of this brand are distinguished by high build quality, unpretentiousness in work and maintenance. Particularly popular models of small power for the home, whose power is from 5 to 8 kilowatts. The equipment for cooling the production of the Japanese company Fujitsu has all the necessary functions: a sleep timer, a self-diagnosis mode, a restart system, etc..

Samsung

Products of the Korean company Samsung are considered economy-class products, they differ from the products of Japanese brands in their affordable price. Samsung inverter air conditioners, despite their reasonable price, are of high quality: all components and assemblies of the air cooler meet quality standards. Reducing the cost of the product is achieved by reducing the service life (7-9 years), and reducing useful functions.

LG Inverter Air Conditioner

The products of the Korean company LG belong to the economy class, the prices of the split system with the LG inverter are significantly lower than for the products of Japanese companies. LG inverter air conditioners are of sufficient quality and reliability, and are popular with customers. Excellent design, the presence of many functions, including automatic cleaning, plasma air purification, ionization make LG products attractive to customers with limited means.

Both types of household appliances for air cooling have their advantages and disadvantages, therefore, when choosing a specific model and variety, you should be guided by the features of the room where it will be installed. Inverter air conditioners are ideal for bedrooms and other rooms with a constant temperature. If in the room doors and windows open from time to time, household appliances that generate heat turn on, there is no point in overpaying: buy an ordinary split system.
