Comparison Electrolux LFB 3AE12 S1 vs Electrolux LFB 3AF12 S

The number of separate chambers with different functionality provided in the design of the refrigerator. Modern refrigerators can be equipped with a refrigerator, freezer, wine chamber, “fresh zones” for fruits and vegetables, etc. The total number of cameras can be up to five.

Single -chamber Single-chamber refrigerators are inexpensive and have a simple design, as they consist of only one chamber, which serves as the refrigerating chamber (refer to "Volume of the refrigerating chamber" for more information).

Two-chamber refrigerators usually consist of a refrigerator and a freezer. Refrigerators can have a freezer that is accessible through the refrigerator compartment or through a separate door. The former is more compact and affordable, but less convenient as it requires opening two doors to access the freezer and defrosting the entire refrigerator.

Three-chamber refrigerators contain a freshness zone, also known as the zero chamber, in addition to the refrigerator and freezer compartments (for more details, see "Freshness zone"). This zone is designed for the long-term storage of fresh products and can increase the price of the refrigerator.

Refrigerators with four or more chambers can have two separate freshness zones (“dry” and “wet”), a wine chamber (see "Wine chamber").

More chambers in a refrigerat...or provide greater storage options for different types of products, but this also increases the price and size of the appliance. The layout of the refrigerator is also important, especially in terms of the location of the freezer.

Forced cooling mode is available in some refrigerators, and it significantly increases the cooling intensity of the refrigerator compartment. It's important to note that fast cooling needs to be turned on and off properly to avoid overloading the compressor. Some models have an automatic shut-off feature, but it's important to check for this feature separately.

The forced freezing mode briefly lowers the temperature inside the freezer to as low as -24 °C or -32 °C. This fast freezing function needs to be turned on in advance and has a limited operating time. Some models do not have automatic shutdown, so it's important to clarify these details. It's worth noting that drawers or quick-freeze zones are not considered as this function.

The energy class that the refrigerator corresponds to.

Energy consumption classes were originally designated with Latin letters from A (the most efficient) to D (least efficient), but with technological advancements, more advanced classes such as "A+", "A++", etc. were introduced to indicate increasing levels of efficiency. The more pluses a device has, the more economical it is. This was necessary due to the correlation between energy consumption and decreasing efficiency.

For modern built-in refrigerators, the efficiency indicator at the level of class A can be called average, A+ — not bad, A++ — good, A+++ — excellent. Energy consumption rates B and C are rare and mostly found in outdated or cheaper models. Achieving high efficiency requires design innovations, which results in higher device prices. However, these prices can be justified by the resulting reduction in electricity bills. It's worth noting that some built-in refrigerator models are available in different energy consumption classes, allowing customers to choose the best option for their budget and energy efficiency needs.

The energy efficiency of a refrigerator is measured by a parameter classified from A to G, with A being the most efficient. Originally, only up to class A was available until newer, more efficient models were introduced and labeled as A+, A++, and A+++. However, in March 2021, manufacturers reverted to the original labeling system from G to A to avoid creating more pluses. This means that modern models will have the new labeling system, while older ones will maintain their original markings.

The average amount of energy consumed by a refrigerator in a year of operation.

The given parameter is an estimated value and assumes that the refrigerator operates under stable conditions without sudden temperature changes, frequent door openings, and within its designated climate class (see below). Actual energy consumption may deviate slightly from the stated value. Despite this, it is a useful parameter that allows for a rough comparison of different models in terms of energy efficiency.

It should be noted that the energy consumption per year is often a more practical and convenient parameter than the energy consumption class (see above), which is a relative indicator of how efficient a refrigerator is compared to other models of similar size and features. The energy consumption per year, on the other hand, provides an estimate of the actual electricity cost when using a particular refrigerator. For instance, a small two-door refrigerator with an energy class of A can consume less energy per year than a large side-by-side refrigerator with a class of A+++, despite the fact that the latter is formally more energy-efficient than the former in terms of its energy class.

This parameter describes the climate conditions for which a particular refrigerator model is designed. A more powerful cooling system and better thermal insulation are required for the refrigerator to operate efficiently in hot conditions compared to low air temperatures. If the refrigerator is not designed for the specific climate conditions it operates in, it may not function efficiently or may even fail.

— SN (subnormal).Refrigerators of this class are intended for use in temperate climates with relatively low temperatures. They are designed to operate within a temperature range of +10°C to +32°C, which is slightly lower than class N. These refrigerators can be particularly useful in poorly insulated rooms where the temperature can drop below +16°C during the colder seasons.

— N (normal). Models designed for moderate climate, with ambient temperature from +16 °C to +32 °C.

— ST (subtropical). Although named after subtropical climates, these models are suitable for both subtropical and tropical climates with high humidity. They can operate within a temperature range of +18°C ... +38°C.

— T (tropical). Units designed primarily for dry tropical climates. They operate at ambient temperatures from +18 °C to +43 °C.

to the development of refrigerators with combined climate classes and enhanc...ed features. These models are characterized by both upper and lower classes, such as N-ST, indicating a wider operating range from the lower limit of the lower class to the upper limit of the upper one. For instance, N-ST corresponds to a temperature range of +16...+38 °C. Some models even combine all four classes, such as SN-T, which has an extended range of +10...+43 °C.

With climate change affecting many regions, the introduction of combined climate classes has become increasingly important. In some areas classified as temperate, summers have become hotter while winters remain cold, and a single climate class such as N may not provide adequate coverage for the required temperature range.

Allows people to decode the values of the noise level in decibels. It is marked in Latin letters like other classes, where A is the quietest class of refrigerators.

— Door sliding — a special type of mount for a built-in refrigerator, in which the decorative facade rests on the hinges of the cabinet, and the refrigerator door itself is only partially loaded. The sliding fastening of a built-in refrigerator's facade allows the door of the fridge to slide along the guides on the inside of the decorative panel, reducing the load on the hinges and increasing the appliance's durability. However, this can create a gap where dust can accumulate, and the door can only open up to 90-95˚, which may cause inconvenience when accessing shelves and drawers.

— Door on door — a special type of fastening of a built-in refrigerator, in which the front decorative facade is hung directly on the refrigerator door. With this type of installation, the front decorative panel of the refrigerator is fixed directly onto the door hinges. The main advantage of this rigid attachment method is that the refrigerator door can be opened wider, up to 110-115˚ or even more. Furthermore, there is no gap between the door of the refrigerator and the decorative panel, which creates a sense of structural integrity. However, one drawback of this method is that it can create additional weight load on the refrigerator door hinges, leading to sagging if they are not designed to bear the weight of the panel.
