Comparison Samsung RB37K63612C black vs Samsung RB37K63602C black

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.

Approximate amount of fresh food that a refrigerator can completely freeze from room temperature to freezer operating temperature in 24 hours. Power up to 10 – 15 kg/day will be quite enough for everyday use, but if you plan to freeze food in large volumes and often — you should pay attention to more performant freezers.

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.
