When choosing a refrigerator, most people pay attention to its size, color, the presence of the necessary functions. But few people pay attention to the most important thing. The main element of each refrigerator is a compressor. It is thanks to this element that they are able to cool, freeze, and ensure the circulation of freon. To choose the best option, you should consider which compressors are best for modern refrigerators, the basic principle of operation, features of various types.
The main types
Even high-quality refrigerator sooner or later it may fail. In this case, you will need to buy a new one. When buying a new model, it is necessary to evaluate not only the appearance and functionality, but also the type of compressor. The efficiency and durability of the equipment will depend on its quality.
Collector
It belongs to the simplest. Installed in old units. The principle of its operation is that it works until the indicated temperature is established in the chamber. Then it turns off. This type of device is the simplest. And the models that are equipped with them are among the most affordable.
Models with one or two collector devices are available. If there are two, then one works for the freezer, and the second for the refrigerator. It has a higher cost. But its feature will be the ability to include only one camera. In such models, both drip and dry freezing systems can be used.
Invertor
The inverter compressor is installed in the most modern models. It does not turn off completely. When a certain temperature is reached, the speed is simply reduced. During the day, there are not many on and off switches that lead to wear of the motor. The inverter motor does not stop working after reaching a certain temperature. This ensures a longer life.
The most popular developer of this type of refrigerator is Samsung, which gives a 10-year warranty on all models, which indicates the reliability of the designs. Benefits include low noise and energy efficiency. In addition, such devices do not work constantly at high power with regular on and off cycles, which ensures a long service life. Therefore, it is the manufacturers of inverter devices that give a multi-year warranty on their products.
Linear
There are models that use the linear type. The principle of its action combines the two previous types. Its advantage is profitability and durability.
Its difference from the inverter device is the absence of extra friction points. Its pistons work due to the electromagnetic field, therefore, it minimizes noise from work, as well as wear of parts. Wherein linear compressor Unlike inverter, it turns off when the required temperature is reached. Most commonly used on LG models with a dry freeze system.
Features and benefits of various types of compressors
The collector motor is most often installed in household models of the old model. It consists of one or more cylinders, in which there are pistons that carry out the movement of freon. Its benefits include:
- simplicity of construction;
- low cost;
- ease of repair and maintenance;
- gives high air pressure;
- high wear resistance at constant work or rare inclusion.
Disadvantages:
- high level of noise and vibration;
- low rate of performance;
- the need to use a filter system;
- regular maintenance is required.
The inverter compressor runs continuously, and does not turn off when the required temperature conditions are reached. This ensures a constant temperature regime with minimal energy consumption. The advantages of the device include:
- maximum power is not constantly used;
- economical energy consumption;
- silent operation is ensured by continuous operation, and not on and off, as in normal;
- long service life.
The obvious advantages of an inverter device make them extremely popular. However, they have a number of disadvantages:
- the device has a complex design and production technology, so its cost is higher;
- low resistance to voltage drops, so it is not recommended to use such models with poor wiring.
The linear device operates in three stages, including turning on, cooling, and turning off. Such a refrigerator is very quiet. It has a long service life. Rarely causes problems during operation. The movement of the piston in it is due to the action of electromagnetic forces. Therefore, power consumption is 40% lower.
The main advantages include:
- long service life due to fewer moving elements;
- minimum temperature deviations in the refrigerator and freezer;
- economical energy consumption;
- minimal noise thanks to a smooth start-up system;
- the long shelf life of products in this refrigerator is provided by the rapid cooling of products.
It should be mentioned the disadvantages of this type of device:
- when disconnected, a characteristic click is heard;
- at startup, power increases sharply, which leads to increased energy consumption.
Thus, ideal compressors do not exist.
Compressors: which are, and which are better
There is no rating of the best compressors for the refrigerator. Most modern manufacturers produce only models of refrigerators with a compress of a certain type. In this case, you need to decide for yourself which is more important - choose a refrigerator based on the manufacturer or type of compressor. Some manufacturers are developing their own models. These companies include LG and Samsung.
From the choice of the type of compress will depend on how long the refrigerator will work without replacement and repair. Therefore, it is best to buy a model with an inverter device. They are characterized by a long service life and minimal energy consumption.
Linear devices are the optimal solution for those who value long-term freshness of products. Collector models, although they are among the simplest and oldest. But at the same time, due to their affordable price, they are also popular.
