Inverter compressor in the refrigerator

A refrigerator is a necessary type of household appliance to equip a kitchen. Its acquisition involves a careful study of the characteristics, including the type of compressor. This is the basic element that ensures functioning.

The productivity and durability of the refrigerator depends on the chosen option, so even before making a purchase, you need to study the features of the device in detail. Among the main types, inverter type stands out, which has a lot of advantages.

Design and principle of operation of an inverter compressor

The creation of the inverter compressor occurred relatively recently, which was based on the knowledge that the developers had as a result of long-term operation of the linear type of design. This is the main feature, since it was possible to take into account all the shortcomings of the older model and correct them in the new generation.

The operating principle of the inverter type is as follows:

• turning on (starting) the device;
• as a result of its operation, the chamber inside is cooled;
• Productive operation allows you to maintain the established temperature regime;
• the speed decreases, but the functioning does not stop completely.

The inverter compressor is characterized by smooth and measured operation. In some cases, it is comparable to the operation of a car engine that moves along a highway.

From the point of view of technical science, the inverter type of motor is capable of converting alternating current into direct current. Next, the reverse process occurs, only taking into account the desired frequency of alternating current.

The use of inverter compressors is typical not only for refrigeration units, but also for equipping medical and computer equipment. Also often used in the design of technical equipment for measuring and servicing vehicles.

What is the difference between an inverter compressor and a linear one?

The operation of inverter and linear types of compressors has many differences. The very fact that the new type was made taking into account the mistakes of the old one speaks volumes. It is typical for a linear one to initially reach maximum speed, and as soon as the desired temperature is reached, it turns off. The operation is regulated using a specially created relay. At the moment of startup, a characteristic clicking sound is heard.

In turn, the inverter model is characterized by continuous operation and lower power consumption. There is also constant temperature support.

Advantages and disadvantages of an inverter motor

In most cases, purchasing equipment with a compressor engine is characterized by a number of advantages. Among these, the following should be noted:

1. Quiet operation. Noise during operation is virtually eliminated, which ensures comfortable operation. There are also no characteristic startup clicks.
2. Low power consumption. Compared to a linear type of compressor, the savings are within 40%, since the engine runs almost continuously.
3. Products are stored in more favorable conditions. Static mode of operation and no temperature changes, which has a positive effect on the products.
4. Duration of operation. The high power level ensures minimal stress on the mechanical elements of the refrigerator. This effect reduces the wear rate of spare parts, and the service life increases.

However, this does not mean that the inverter compressor is completely ideal. There are also disadvantages, which are not many, but they should be taken into account. First – this is the cost, as a rule, it is quite high. If compared with linear, the difference will be about 30%. Second, more minor, is the demands on working conditions. Care must be taken to ensure that the wiring and sockets in the house regularly maintain the same voltage and are in good working order.

Note! In some cases, it won't hurt to purchase a stabilizer. This is necessary when there are frequent voltage fluctuations in the house.

Possible reasons for a breakdown of the inverter system

Despite the fact that the inverter compressor model has many advantages, including a long service life, it can also fail. However, most are preventable. As already noted, there is sensitivity to voltage changes. Inexperienced owners may not take this factor into account when purchasing.

Experts recommend doing the following before purchasing a refrigerator:

• inspect the condition of the outlets;
• replace those that are faulty;
• check the condition of the wiring.

These steps will help prepare the room for the new equipment. In addition, such actions will be useful for prevention purposes.

Many manufacturers of modern household appliances take into account this specific operation of inverter compressors. Therefore, they create protection using Volt Control technology. The operating principle is based on putting the device into standby mode when surges occur. When the situation stabilizes, engine operation resumes.

How to check an inverter compressor

The compressor's health is monitored by starting without an inverter. To do this, you need to connect the simplest light bulbs that connect to the triangle. If none of them lights up when the generator is turned off, everything is working properly. After connecting the inverter and generator, they should light up one after the other.

Tips for choosing a compressor refrigerator

When looking for a good refrigerator, the compressor is an important criterion. However, when purchasing you need to consider:

• noise level;
• life time;
• performance;
• number of compressors.

Recently, models with two compressors have become increasingly popular. This allows for independent operation of two cameras, and it also affects performance and service life.
