A compressor is a very important component of a refrigerator. There are several types of these devices and all of them differ in technical characteristics. The inverter compressor was developed relatively recently and many are not aware of the principle of its operation and advantages. In this article we will talk about the principle of operation and what is an inverter compressor in the refrigerator.
Inverter compressor working principle
When the linear compressor is operating, the device is maximally started. When the set cooling temperature is reached, automatic shutdown is triggered. The relay controls the process of shutting down and restarting the refrigerator. At the moment of switching on and off, a click is triggered. A characteristic buzz indicates the operation of the engine.
With constant operation of the refrigerator at full power and frequent shutdown, the device heats up very much and after a certain time fails, after which replacement of the cooling device is required. One more minus: high electricity consumption due to increased power supply load.
When creating an inverter motor, all of the above disadvantages were taken into account. In general, the device works on the same principle, with the exception of several differences. When the inverter refrigerator is cooled to the required temperature, operation does not stop, but a gradual decrease in speed and a decrease in the speed of the refrigerant occur. Thus, a certain temperature level is maintained.
When you open the refrigerator door, the number of revolutions of the shaft increases according to the signal of the sensor about an increase in temperature and a discrepancy with the required one. Unlike linear, the new generator works more smoothly, using minimal power.
If we explain the inverter operation from a technical point of view, the AC is converted to direct current, followed by the reverse process, but the required frequency is set. A three-phase compressor motor with a brushless system used in the refrigerator is used in the manufacture of automotive mechanisms, computer, medical equipment, etc.

Pros and cons of the inverter refrigeration system
The main advantage of this type of compressor is its low power consumption and long-term operation. Smooth, quick temperature control and silent operation are the advantages of household appliances with this type of engine.
When buying a refrigerator with an inverter motor, a warranty is issued for a period of about 10 years. This confirms the reliability of the device and the confidence of the manufacturer in the quality of their goods.
However, a refrigerator with a linear compressor is cheaper than with an inverter cooling system, so it continues to be in demand. Along with the high price, the inverter device has another minus. Voltage drops can cause a malfunction in the refrigerator, as this type of compressor is more complicated than a conventional engine. Wiring in the room must be reliable. Otherwise, installation of stabilization devices is required.
Regardless of the presence of shortcomings, such a device is gaining popularity among buyers. Gradually, the market is filled with new, more advanced models. Modern production is not limited to refrigerators - an inverter compressor is already an integral part of air conditioners, washing machines and other household appliances.

15 years ago, refrigerators worked until the first breakdown of 25 years. They were made of non-ferrous metal. They were without electronics and inverter compressors.
Thanks to the author for a detailed explanation of the inverter compressor device. It became clear that it was necessary to include such refrigerators in the network through the stabilizer, otherwise the repair price would be comparable to the cost of a new refrigerator.

We have had such a refrigerator for 6 years. And suddenly turned off, all the light bulbs went out. The masters from the service department called. Understand what the cause of the failure can not. On the Internet, specialists were found “from the side”. They say that the reason is in the compressor. As we understand it, it is not profitable for the after-sales service to install the compressor under warranty (10 years on the compressor), although the installation work costs a lot. And third-party offer to install for 25 thousand rubles: compressor plus work. So what to do? We will take)))
Good day.
What brand of refrigerator?
For 25 thousand rubles. can I buy a new one, not more profitable?
