Many people know that the compressor is the most important part in the refrigerator. But not everyone is able to distinguish between their species. Let's talk about the inverter compressor. What is it, and what are its advantages?

Principle of operation

A conventional linear compressor starts at a maximum, runs, and switches off automatically when the temperature in the refrigerating chamber reaches the set value. The on-off process is regulated by a relay. If you listen, you will surely hear a characteristic click at the time of launch and at the time of disconnection. When the refrigerator hums, you realize that its engine is running.

Constant switching on at full power and turning off leads to a strong heating of the compressor in the refrigerator, over time it can fail, and then you have to buy a new cooling device. In addition, when starting up, the load on the power grid increases, which leads to increased power consumption. All this has led to the invention of the inverter model. The principle of its work is as follows.

• Initially, the inverter compressor is turned on( without this in any way).
• During its operation, the camera is cooled inside.
• The operation of the inverter maintains the desired temperature in the chamber.
• Compressor slows down, but does not turn off completely.

Work is carried out smoothly, measuredly. Sometimes it is compared to the work of the engine of a car driving along an ideal highway. In contrast, a linear compressor is compared to a car moving over bumps, steep climbs and sharp descents.

If we speak in a more technical language, the inverter motor converts alternating current into direct current, and then again into alternating current, only the necessary frequency for it. Brushless three-phase motor is used. Such engines are also used for the production of measuring, medical equipment, computer, automotive equipment, etc.

Advantages and disadvantages of the inverter compressor

The advantage of the inverter engine is that it saves energy and prolongs the service life of the electric device. You can adjust the temperature smoothly and quickly, while the refrigerator is much quieter, which is very important for small apartments.

The fact that the refrigerator can last longer, eloquently says an extended warranty. Many companies extend the warranty time to 10 years, because they are confident in the reliability of new models.

The traditional refrigerator with a linear compressor still continues to enjoy popularity, since its cost is lower. In addition to the price of a refrigerator with an inverter engine has another drawback. His device is more complex and it is sensitive to voltage drops in the network. Before buying and installing the device, make sure that the wiring in your house is secure and, if necessary, install stabilization devices.

Despite all this, new, more advanced models are appearing on the market, dragging buyers to their side. In addition, inverter air conditioners and washing machines are available. This leads to qualitative changes in household appliances, and also negates the possibility of repairing it with your own hands in the event of a complex breakdown.
