What is an inverter compressor in a refrigerator?

The compressor is a very important component of the refrigerator. There are several types of these devices and they all differ in technical characteristics. The inverter compressor has been developed relatively recently and many do not know about its operation principle and advantages. In this article we will talk about the principle of operation and what is an inverter compressor in a refrigerator.

The principle of operation of the inverter compressor

When the linear compressor is operating, the device is started up to the maximum. When the set cooling temperature is reached, an automatic shutdown is triggered. The relay controls the process of shutting down and resuming the operation of the refrigerator. At the moment of switching on and off, a click is triggered. A characteristic buzz is indicative of engine performance.

With constant operation of the refrigerator at full capacity and frequent disconnection, the device becomes very hot and after a certain time fails, after which the cooling device needs to be replaced. Another disadvantage: high consumption of electricity due to increased electrical load.

When creating an inverter motor, they took into account all the listed disadvantages. In general, the device operates on the same principle, with the exception of a few differences. When the inverter cooler is cooled to the required temperature, the work does not stop, but there is a gradual decrease in speed and a decrease in the speed of the refrigerant. Thus, a certain temperature level is maintained.

When opening the door of the refrigerator, the number of revolutions of the shaft increases when the sensor signals that the temperature rises and does not comply with the required one. Unlike the linear, the new generator runs more smoothly using minimal power.

If we explain the inverter operation from the technical point of view, the alternating current is converted into direct current, followed by the reverse process, but the required frequency is specified. The three-phase compressor motor with a brushless system used in the refrigerator is used in the manufacture of automotive mechanisms, computer, medical equipment, etc. This type of compressor is low power consumption and long-term operation. Smooth, fast temperature adjustment and silent operation are the advantages of household appliances with this type of engine.

When buying a refrigerator with an inverter motor, the warranty is issued for a period of about 10 years. This confirms the reliability of the device and the confidence of the manufacturer as its product.

However, a refrigerator with a linear compressor costs less than with an inverter cooling system, so it continues to be in demand. Along with the high price, the inverter device has one more minus. Overvoltage of the network can lead to a malfunction of the refrigerator, since this type of compressor is more complex than a conventional engine. Wiring in the room should 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.
