Refrigerators are firmly entrenched in our lives. They help preserve the pristine freshness of products and preserve them as much as possible.
For this, most models are equipped with built-in freezers. They decided to store meat and other products that deteriorate at high temperature.
In this situation, a lot depends on the power of the freezer in the amount of kW consumed per day. Payment for light also depends on the amount of energy consumed, so the question of how many watts are consumed on average per day becomes especially relevant.
It’s even more offensive if the equipment purchased consumes too much energy, despite the fact that there are analogues in properties that are not inferior to your freezer, but cheaper, which have several times lower consumption.
We will consider in detail the question of the types of freezers, average consumption rates, as well as the energy efficiency of each type of freezers.
Types of freezers
One of the main factors determining the characteristic of the freezer is the average power of the compressor - the device responsible for the production of frost. It is determined by the number of products frozen during the day to a temperature inside the chamber itself.
So, a standard freezer, built into the refrigerator, can cope with the freezing of 5-15 kilograms of food. The cameras are capable of producing temperatures from -6 to -32 degrees Celsius. There are several types of freezers.
Freezers
This type of freezer is very similar to ordinary refrigerators. Sections are separated by plastic partitions, since plastic insulates odors to a large extent. Most freezers have a No Frost system, thanks to which the walls are not covered with ice, and you do not have to defrost the chamber from time to time. They are compact enough, so they won’t take up much space.
Freestanding cabinets are not very popular, but built-in cabinets are considered one of the best in terms of compactness and freezing efficiency. However, No Frost technology requires additional energy costs, therefore, profitability in this case is the main minus of the freezer.

Freezer chest
This kind of equipment can be found both in stores and in homes. The chest freezer is considered one of the oldest types of freezers. In terms of volume, it is much larger than standard cabinets. All products are stored in special trays. Most of the chests are not equipped with the No Frost system, so ice will settle on their walls, which is why the chest will have to be periodically thawed. However, this chest freezer is able to accommodate a fairly large amount of food. Moreover, the equipment is quite economical both in terms of placement and in terms of electricity consumption. For this reason, GELs are still very popular.

Freezer showcase
Such devices can hardly be found in homes. Most often they are used in stores, putting products on public display. Their power is not very large, however, the storage conditions of meat and dairy products do not require freezing.

Freezer control system
Freezers can be controlled using mechanical or electronic switches. The former are convenient in that the mechanism is fairly easy to master, while the likelihood of a malfunction of the equipment is extremely low.
In the first case, control is carried out using switches and cranes. Most of these devices are equipped with recessed button panels. The image shows the main buttons and indicators.
Control Panel. 1 - quick freeze. 2 - indicator. 3 - temperature indicator, turns on when a malfunction occurs. 4 - this light turns on when the device is operating normally. 5 - mechanical regulator
The electronic system is most often equipped with the same buttons, but at the same time in some models there is also a display that reflects the current state of technology. More advanced cars are equipped with touch-sensitive switching mechanisms. With such a switch, it is much easier to choose the optimal mode for freezing products and set the desired temperature.

Classification of energy systems
As you know, the energy consumed is converted into kilowatts. The energy consumption level of freezers is divided into classes, which are indicated by letter codes from A to G.
Recently, models of the A ++ class have also come into widespread use. Some manufacturers, using additional thermal insulation, thus provide a more economical energy consumption.
In this case, the question arises which of the devices is more economical. Here you should consider the average consumption for each type.
A conventional cabinet-shaped freezer consumes an average of 190 watts per hour. The No Frost system provides additional load on the compressor, and also activates the fans, which also contributes to increased energy consumption.
The chest freezer is not only good in capacity and affordable, but also economical: the average level of energy consumption is about 80 watts per hour. Therefore, for those who are looking for an economical option, it is the freezer chest that is best suited.
Energy Type Classification
Conclusion
Most consumers prefer to use the built-in freezers that come with the refrigerator. However, the volume of such a camera is much smaller, so those who store a large number of products will need a freestanding model.
The choice is truly great, but in the basic characteristics of the model, in principle, are similar.
It is also worth noting that the chest is a more economical option than the camera in the form of a cabinet, however it is less compact and will take up more space in the room.
