Number of compartments
it is the number of compartments provided in the design of the freezer. In some models, it is possible to set different temperatures for different compartments. It is worth noting that a large number of boxes does not always mean maximum convenience, since, with an increase in their number, the volume of each individual box inevitably decreases.
Big drawer
The presence of a larger drawer in the freezer. Such large containers allow you to store a whole turkey and other large products. It is worth noting that the concept
of a large drawer may vary depending on the manufacturer - in some cases it is quite possible that it will be comparable to a classic drawer of another model.
Fast freeze
It is the forced freezing mode, in which the temperature inside the freezer is briefly reduced to -24 °C. This mode is intended for the case when you need to freeze numerous products at the same time — without a sharp decrease in temperature, the heat from numerous non-frozen products could lead to its critical increase.
Usually, the fast freeze mode must be turned on in advance — 5 to 6 hours before loading the products. Thus the freezer has time to decrease the temperature in the chamber. In this case, it is necessary to take into account the increased load on the compressor — it is impossible to turn on fast freeze for a long time. In some models, automatic shutdown of the fast freeze mode is provided. In some, it must be done manually.
Energy class
The energy class shows how economical the freezer is in terms of electricity consumption. Initially, the classes were designated in Latin letters from A (most economical) to G (high power consumption). Recently, improved classes A+, A++ and A+++ appeared (the more pluses - the more economical the device).
It should be borne in mind that this indicator represents not the actual energy consumption but the efficiency of the unit compared to similar models. Therefore, a small class A freezer may have a lower power consumption than a large class A++ model. And other things being equal, a more economical device, as a rule, costs more, but this difference can quickly pay off during the operation.
Energy consumption per year
It is the average amount of energy consumed by the freezer in a year of operation. Of course, these figures are not absolutely accurate. The actual power consumption may vary depending on the specific operating conditions. However, this parameter makes it possible to evaluate the consumption of the device and compare different models with each other. At the same time, it often turns out to be more convenient and visual than the energy consumption class (see above) because, in this paragraph, we are talking about a specific figure (from which you can also calculate the cost of electricity consumed).
