A refrigerator is a necessary type of household appliances for equipping a kitchen. Its acquisition involves a thorough 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, therefore, even before making a purchase, you need to study the features of the device in detail. Among the main types, inverter stands out, which differs in a lot of advantages.
The device and principle of operation of the inverter compressor
The inverter compressor was created relatively recently, which was based on the knowledge that the developers had as a result of the 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 principle of operation of the inverter type is as follows:
- inclusion (start) of the device;
- as a result of its functioning, the chamber is cooled inside;
- productive work allows you to provide support for the set temperature;
- reduction in speed, but fully functioning does not stop.
The inverter compressor is characterized by smooth and measured operation. In some cases, it is comparable to the operation of a car engine that makes movements along the highway.
From the point of view of technical science, an inverter type of motor is capable of converting alternating current to direct current. Next, the reverse process occurs, only taking into account the desired frequency of the alternating current.
The use of inverter compressors is characteristic 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
The operation of inverter and linear types of compressors have many differences. The fact that the new look was made taking into account the mistakes of the old, says a lot. It is typical for a linear one to initially gain maximum speed, and as soon as the desired temperature is reached, a shutdown occurs. Operation is controlled by a specially designed relay. At the time of launch, a distinctive click sound is heard.
In turn, the inverter model is characterized by continuous operation and lower power consumption. Also noted is the constant support of the temperature regime.
Advantages and disadvantages of an inverter motor
In most cases, the acquisition of equipment with a compressor engine is characterized by the presence of a number of advantages. Among these, the following should be noted:
- Silent work. The noise during operation is virtually eliminated, which allows for comfortable operation. There are also no distinctive launch clicks.
- Low power consumption. Compared to the linear type of compressor, the savings are up to 40%, since the engine runs almost continuously.
- Products are stored in more favorable conditions. A static mode of operation and no temperature differences, which positively affects the products.
- Duration of operation. A high level of power ensures a minimum load 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 absolutely perfect. There are also disadvantages, which are not many, but they should be taken into account. The first - this is the cost, as a rule, it is quite high. Compared to linear, the difference will be about 30%. Second, more insignificant, it is exactingness to working conditions. It is necessary to ensure that the wiring and sockets in the house regularly maintain the same voltage and are serviceable.
Note! In some cases, it does not hurt to buy a stabilizer. This is necessary when tension often jumps 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 can be prevented. As already noted, sensitivity to voltage drops is observed. Inexperienced owners may not consider this factor when buying.
Experts recommend that you do the following before purchasing a refrigerator:
- inspect the status of outlets;
- replace those that have failed;
- check wiring status.
These steps will help prepare the room for new equipment. In addition, for the purposes of prevention, such actions will be useful.
Many manufacturers of modern household appliances take into account such specifics of inverter compressors. Therefore, they create protection using Volt Control technology. The principle of operation is based on putting the device into standby mode when jumps occur. When the situation stabilizes, the engine resumes operation.
How to check inverter compressor
The compressor is monitored by starting without an inverter. To do this, connect the simplest bulbs that connect to the triangle. If none will burn when the generator is turned off, everything is working properly. After connecting the inverter and generator, they should flash one after another.
Tips for choosing a compressor refrigerator
In the process of finding a good refrigerator, the compressor is an important criterion. However, when buying, you need to consider:
- noise level;
- life time;
- performance;
- number of compressors.
Recently, models with two compressors are gaining more and more popularity. This allows you to get independent operation of two cameras, in addition, it affects the performance and duration of operation.
