The compressor is a very important part of the refrigerator. There are several types of these devices and they all differ in technical characteristics. The inverter compressor was developed relatively recently and many do not know about its working principle and advantages. In this article we will talk about the principle of operation and what is an inverter compressor in the refrigerator.
The principle of operation of the inverter compressor
When the linear compressor is running, the maximum start-up of the device is performed. When the set cooling temperature is reached, an automatic switch-off is activated. The relay controls the process of shutting down and resuming the operation of the refrigerator. There is a click when turning on and off. A characteristic buzz indicates the operation of the engine.
With the constant operation of the refrigerator at full power and frequent shutdowns, the device gets very hot and after a certain time fails, after which the replacement of the cooling device is required. Another disadvantage: high electricity consumption due to increased electrical 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 a few differences. When the inverter refrigerator cools down to the required temperature, the operation does not stop, but there is a gradual decrease in speed and a decrease in the refrigerant speed. Thus, a certain temperature level is maintained.
When the refrigerator door is opened, the number of revolutions of the shaft increases according to the sensor signal about the temperature increase and discrepancy with the required one. Unlike a linear generator, the new generator runs more smoothly using minimal power.
If you explain the inverter operation from a technical point of view, the AC is converted to DC, followed by the reverse process, but at the same time the required frequency is set. The brushless three-phase compressor motor used in the refrigerator is used in the production of automobile machinery, computer equipment, medical equipment, etc.

Pros and cons of an inverter refrigeration system
The main advantage of this type of compressor is low power consumption and long-term operation. Smooth, quick temperature control and quiet operation are the advantages of household appliances with this type of engine.
When buying a refrigerator with an inverter motor, a guarantee 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 its product.
However, a linear compressor refrigerator costs less than an inverter refrigeration system, so it continues to be in demand. Along with the high price, the inverter device has another disadvantage. Mains voltage fluctuations can lead to a malfunction of the refrigerator, since this type of compressor is more complex than a conventional engine. Wiring in the room must be reliable. Otherwise, the installation of stabilization devices is required.
Regardless of the 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 — the inverter compressor is already an integral part of air conditioners, washing machines and other household appliances.
