Comparison LG GW-B449BMFZ silver vs LG GW-B499SEFZ beige

The total capacity of the refrigerator is the total capacity of all the main working chambers: refrigerating, freezing, zero, and wine chambers. The set of these chambers, of course, will be different in different models (see more about them above). Here we note that large volumes, on the one hand, simplify the storage of numerous products and, on the other hand, affect the dimensions and price of the unit. It is also worth considering that refrigerators of the same total capacity may differ in the capacity of individual chambers.

Various special features provided in the refrigerator, such as holiday mode, control via smartphone, child lock, ( LED display or TFT display), door alarm reversible door. And now in more detail:

— Holiday mode. A special mode of operation in case of a long absence of users — when there is no foodstuff in the refrigerating chamber and there is no need for the unit to work intensively. In holiday mode, the temperature inside is maintained at about 12 °C; this prevents the growth of mould and unpleasant odours, while the energy consumption is very low.

— Control via smartphone. The ability of access to control the refrigerator via the Internet. The refrigerator, usually, is connected to the World Wide Web using Wi-Fi — via a router or a smart home system. The convenience of this function is obvious: it allows you to control the operation of the unit from anywhere in the world where there is an Internet connection. However, the specific implementation of such control may be different: some models of refrigerators use an application installed on a smartphone or tablet, and others allow you to work through a web page available in any browser. However, the user can thus obtain various data on the unit's operating mode (temperatur...e and humidity in the chambers, the use of special functions, malfunctions and emergencies, etc.) and, if necessary, change its settings.

— Child lock. Various features to keep your refrigerator safe from small children. Often, it means blocking the control panel — so that a curious baby cannot change the settings.

— Display. Refrigerators of any level can be equipped with displays — from the simplest to the most advanced. Anyway, the screen provides additional convenience in operation: it can display various detailed information about the operation of the unit, as well as other useful data (for example, time). But the specific type of display may be different.
— LED display. Usually, they are very simple — they display one colour (maximum two or three basic colours) and a limited set of characters (numbers, individual letters and some special icons). However, such limited functionality is enough even for fairly advanced refrigerators, and LED displays are inexpensive.
— TFT display. These are already the most functional screens — like those used in smartphones, tablets, etc. They are capable to display a huge variety of information and can even be made touch-sensitive. And some units with TFT displays are not just refrigerators at all but multifunctional smart home components. However, such an appliance costs accordingly.

— Door alarm. An alarm system that warns that the refrigerator door is open for a long time (or not closed tightly enough). After some time after opening, such a system gives a signal (usually sound), notifying the user of the need to check the status of the door. It avoids a critical increase in temperature in the refrigerator chamber and damage to the contents. In some models, this system is also complemented by a light indicator that confirms the correct closing of the door — this further reduces the risk of leaving the refrigerator loosely closed.

— Reversible door. The ability to choose from which side the hinges on the refrigerator door will be located and, accordingly, in which direction it will open. It allows you to optimize the space in the kitchen, providing access to the contents of the unit from the most convenient side. Please note that this function is only available for classic design models, including display refrigerators (see “Product type”). In Side-by-Side and French Door refrigerators it makes no sense to provide this feature.

These features relate exclusively to the design and overall appearance of the refrigerator. These features include glass door panel, hidden door handles, handle illumination, customizable panels and retro design. Here is a detailed description of all these items:

— Glass door panel. Refrigerators with this feature have glass doors on the outside. This finish does not affect the functionality of the device but gives it a stylish appearance due to the specific glare on the glass surface. And in some models, a decorative pattern can also be applied to the glass. In addition, such a coating is very resistant to scratches. Its disadvantage is a rather high cost. So the glass door panel is typical mainly for “designer” refrigerators, created with an emphasis not only on functionality but also on the rich design.

— Hidden door handles. Handles made in the form of recesses on the ends of the refrigerator doors. They can be located on the top, bottom and/or side, depending on the design of a particular unit and the location of the door itself. Anyway, thanks to the hidden handles, the refrigerator at least acquires a neat, discreet appearance — with a minimum of unnecessary details on the doors. In addition, a regular handle can be touched by careless movement, but with a hidden one, it is impossi...ble. It is especially relevant in cramped conditions. On the other hand, not all users find hidden handles comfortable enough. Therefore refrigerators with doors of a more traditional design nowadays also continue to be produced.

— Handle illumination. This feature not only gives the refrigerator an interesting appearance but also makes it more visible in low-light conditions. The latter can be useful not only in the evening or at night but also at other times of the day — if the unit is installed in a place that is itself poorly lit. However, there are few models with illuminated handles on the market, and they mainly belong to the middle and premium class.

— Customizable panels. Replaceable panels that allow you to change the appearance of the refrigerator. This feature does not affect the functionality, but it makes it possible to optimally choose the design for the interior of the room and the tastes of the owner. Some units with this feature are initially supplied without decorative panels in the expectation that users themselves choose or order a pattern at their discretion. On the other hand, the real need to use customizable panels rarely arises — even for a non-standard interior, it is easier to choose a refrigerator that was originally made in a certain design. So there are very few models with this feature nowadays.

— Retro design. Refrigerators made in the style of "retro" — in other words, semi-antique. Typically, such models imitate the technique of the 50s — 60s of the twentieth century, with rounded body shapes, massive handles, etc. However, there are other design options — the old sideboard, or even completely non-standard, in the form of a car, aeroplane, etc. Anyway, completely modern technologies are usually hidden under such a case. And the original appearance can be very useful for an interior in an unusual style. On the other hand, it is worth considering that retro design is very expensive. Most of these models are designed for those for whom design is no less important than functionality.

The total capacity of the main working chamber of the refrigerator. If there are separate zero chambers, compartments for wine and other additional functions, this paragraph takes into account only the volume of the refrigerating chamber itself, without additional equipment. In the smallest modern units, this figure does not even reach 100 liters, in the largest it can exceed 400 liters.

The choice of capacity depends on the actual storage needs of the products. At the same time, both the volume of stocks and the frequency of their replenishment (every day, once a week, etc.) matter. The chamber should not be stocked completely; this adversely affects the quality of the refrigerator. On the other hand, it is worth remembering that large volumes accordingly affect the dimensions and price of the unit.

In general, for one or two people, a capacity of 200 – 250 liters, or even less, is considered quite sufficient. The optimal capacity for a family of three is about 250 – 300 liters, for four to five people — 300 – 350 liters, and larger volumes are really needed mainly for specific situations when food has to be stored in large quantities and for a long time.

The average amount of energy consumed by a refrigerator 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 power consumption of the refrigerator 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). For clarity, let's take the following example: a small two-chamber refrigerator with energy class A can consume less energy per year than a large side-by-side unit of class A+++, although formally, in terms of energy consumption classes, the second model will be more economical than the first.

The climate class to which the refrigerator corresponds.

As the name implies, this parameter describes the environmental conditions for which the unit is designed. The warmer it is around — the more powerful the refrigerator should be and the better thermal insulation it should have. Specific classes are indicated by letters, here are the most popular options:

— SN (subnormal). Models for a temperate cool climate, have an operating range from +10 °C to + 32 °C. Such a unit can be useful in a poorly heated room where the temperature can drop below +16 °C — for example, on the veranda of a private house, in a garage, etc.

— N (normal). Refrigerators for temperate climates, with an operating temperature range of +16...+32 °C. Such a unit is suitable for most residential apartments and houses in mid-latitudes.

— ST (subtropical). Models for subtropical and humid tropical climates. Normally work at the range of external temperatures +18...+38 °C.

— T (tropical). Refrigerators for dry tropical climates. Designed for temperature range +18 °С to +43 °С.

There are many models on the market with an extended temperature range covering several classes. For example, a unit labelled N-ST will have a temperature range of +16...+38 °C. Such refrigerators are indispensable in complicated...climates, the conditions of which are not covered by one standard class — for example, during cold winters and hot summers.
