Inverter compressor in the refrigerator: pros and cons, differences from traditional devices, protection against breakage

The refrigerator is one of the most important kitchen appliances. After all, you can wash the dishes or do the laundry by hand, and it will be difficult to cool food products without a refrigerator, especially in the warm season. Moreover, technological progress does not stand still, and every day new models of equipment appear - one of such innovations is the inverter system of the refrigerator.

What is an inverter refrigerator

When buying a refrigerator, everyone wants to choose the device with the longest life, optimal power factor and minimum energy consumption. All these parameters will depend on the main part of the refrigerator - the compressor. This device is the heart of technology - thanks to its work it shrinks and the refrigerant moves in the refrigeration system.

Digital control technology, in addition to being used in refrigeration units, is also used in the production of computer, automotive, medical and measuring equipment. The work of the motor consists in converting alternating current to direct current, after which it accelerates to the required frequency level.

All work is managed through a special board. After switching the switch to the desired temperature, the temperature threshold is reached very quickly. With this operation, the temperature threshold remains optimal for a long time.

The inverter motor does not stop running, but reduces power and continues to run at revolutions that allow you to maintain the required temperature in the refrigerator compartment. This slows down the circulation of the refrigerant in the system.

Differences in the operation of motors

There are many differences between linear and inverter compressors. Linear is regulated by a special relay and turns off when the required temperature is reached. With accurate listening, you can hear a mute click. The inverter requires less energy to maintain thermal conditions within a certain range.

Linear compressor

New technologies in the form of an inverter compressor are not yet so widespread - a new type of motor is still a curiosity. The functions of a conventional compressor are turn-on and turn-off. In a conventional device, in order to reach the temperature threshold, the motor must develop its maximum power, after which the refrigerator compartment will cool down, and it will turn off. In the process of such work, clicks alternate, which are emitted in the control relay.

In an inverter compressor, the operation runs smoothly, the parts do not reach the full load due to switching on and off. A temperature measuring sensor is installed in the refrigerator with a linear compressor. When the temperature drops, the motor turns on and again develops maximum speed, and in the process, the sensor periodically measures the temperature. When the required indicator is reached, the motor turns off. Due to this cycle, parts wear quickly.

The principle of the inverter

When the refrigerator is turned on, the set temperature limit is reached very quickly. After that, thanks to the inverter system, the temperature is maintained at optimal motor operation. The compressor smoothly reduces the speed to a certain value to maintain the set temperature regime and does not turn off completely. As a result, the temperature remains unchanged. The power of the advanced compressor can vary from 0 to 100% depending on the set temperature, and in the linear compressor either 0 or 100%.

Main advantages and disadvantages

There are many reasonsaccording to which consumers are leaning towards the new technology:

• Low power consumption. Most manufacturers claim that equipment efficiency is up to 40% in comparison with traditional installations. The effect is obtained due to the absence of a cyclic process of switching on and off.
• The duration of the service life. By reducing the power of the inverter motor in the refrigerator, the load on the mechanism is reduced. As a result, the parts of the mechanism wear out less. Manufacturers guarantee uninterrupted operation of the refrigerator for at least 10 years.
• No clicks of the control mechanism and low noise during the operation of the refrigerator.
• Food storage takes place under better conditions. No difference in the set temperature due to on-off, which is typical for a linear compressor.
• More accurate temperature control.
• Compared to the linear version, there is less load on the power grid, and problems with the grid are minimized.

The inverter installation creates less load on the power grid and the appliances connected to it.

Disadvantages of inverter refrigeration devices very few:

• Price. The price can be up to 30% higher than for conventional refrigerators, while the electricity savings are negligible.
• Sensitivity. Operation must be carried out with good wiring and constant maintenance of the same voltage in the network.

Breakage protection

Improved refrigerators, like any equipment, are susceptible to breakdowns. Therefore, experts recommend checking the serviceability of the unit before purchasing this type of installation. the electrical network, since most often the causes of failure of mechanisms are unreliable wiring and drops voltage. Even with a slight surge in voltage, the compressor can be damaged. In connection with this trend, manufacturers are producing the Volt Control protection system. Thanks to this technology, the device goes into standby mode and does not work until the voltage level is restored.

Consumer reviews

After buying a refrigerator, many consumers claim that the new type of refrigerator does not have significant differences. This displeasure is due to the lack of knowledge about technology. The refrigerator can be with a linear compressor on inverter control, that is, motor control, and respectively, and the temperature in it, is produced not by the control relay, but by means of a semiconductor technologies. The operation of a linear compressor is a reciprocating motion.

An alternating current is generated in the compressor, which affects the rotating rotor. When current flows into the device, an alternating magnetic field is formed inside, acting on the rotor. This is how electromagnets are formed in the device, thanks to which the motor is driven.

Thus, any compressor can be controlled by an inverter system, but all the benefits can only be achieved by redesigning the compressor itself. Therefore, do not confuse inverter compressor and refrigerator with inverter control technology.
