Type
The type of refrigerator is specified if the design of the unit differs markedly from the
classic one (vertical layout, one or more doors for the entire width of the device). Nowadays, there are three main varieties of such non-standard models:
Side-by-Side and
French door refrigerators, as well as
display refrigerators. Here is a more detailed description of each of these varieties:
— Side-by-Side. Refrigerators of this type have at least two doors stacked side by side (hence the name). If there are more than two doors, then at least one of them occupies the entire height of the unit. It is how similar models differ from French Door refrigerators (see below). Another difference is that the compartments in the Side-by-Side models have a vertical layout: the freezer is usually located on the side and is completely covered by one of the doors. Anyway, refrigerators from this category have large dimensions and high capacity. They are designed for spacious kitchens and large amounts of food.
— French Door. It is a specific variation of the Side-by-Side models described above: French Door refrigerators also have a large width and side-by-side doors. The main fundamental difference lies in the internal layout: the refrigeration compartment in such units is located horizontally, across the entire width of the unit. In addition,
...in traditional French Door models, not two but four doors are provided — two pairs at different levels. There is also another, rarer version of the design — two doors on top (side by side) and drawers for the entire width of the unit from below. However, the refrigerator compartment in such models necessarily has a pair of doors. Anyway, the specifics of using French Door refrigerators are similar to Side-by-Side: these are spacious units designed for kitchens with a lot of free space. Their main advantage lies in the fact that the layout of the “2 doors per chamber” format allows you to reduce cold losses when opening: in the classic French Door, opening one door opens only half of the refrigerator or freezer, while in Side-by-Side models the corresponding chamber opens entirely. Yes, and the location of the cameras one above the other, many users find it more convenient than side-by-side. On the other hand, numerous doors complicate and increase the cost of the design.
— Display refrigerators. Refrigerators intended primarily for commercial use. The main feature of such units is transparent doors that allow you to see the contents without opening the chamber and without violating the temperature regime. As for other specifications, display refrigerators cases usually have a traditional vertical layout, small or medium volume and are not equipped with freezers. At the same time, there can be two chambers in the design, but they not always have separate temperature control — the meaning of this design is primarily to reduce cold losses with each opening and optimize the distribution of contents over the internal volume. Anyway, display refrigerators are especially suitable for the sale of chilled drinks. Although, they can also be used for food products that require storage at low (but not sub-zero) temperatures.Total capacity
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.
Features
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.Refrigerator capacity
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.
Cold water dispenser
Cold water supply system built into the refrigerator. The specific functionality
of the dispenser varies: water can come from a built-in container or from a water supply to which the unit is connected; the design often includes filters of one type or another; different models may differ in performance and cooling speed, etc. However, in any case, this function has its advantages. In particular, pouring water from a dispenser is much more convenient than cooling it in bottles or other containers.
In the vast majority of refrigerator designs, the dispenser is placed externally - on the outside of the door. To get cold water, there is no need to open the main compartment again - this minimizes heat loss and helps save energy. However, there are also models with an internal dispenser, for which a place is carved out in the refrigerating chamber of the unit.
Quick access (minibar)
A small door that provides
quick access to individual shelves in the refrigerator compartment without opening the entire unit door. It can also often be called a minibar - most often, soft drinks are taken out through such a door. The small size of the door for easy access helps to save energy - less extraneous heat gets into the unit. In this case, the additional door is usually made transparent, so that you do not need to open the refrigerator at all to check the contents. On the other hand, for a number of reasons, a minibar makes sense only in units of larger sizes - Side-by-Side and French Door formats (see “Type”); however, this design feature significantly affects the cost.
Freezer compartment
The freezer, if present, may be positioned differently relative to the main compartment of the refrigerator. In classic units and French Door models (see "Product type"), the
bottom location of the freezer is found predominantly (in some cases, such a freezer has a
retractable design).
The top location is noticeably less popular, although it is also used quite often. Side-by-
side freezer models are almost all in the Side-by-Side category (see "Type"). And some modern refrigerators may
not have a freezer at all. Here is a more detailed description of each option:
— Bottom. By installing the freezer at the bottom, you can raise the main (refrigerator) compartment to the optimum height: it will be in front of the user’s eyes, and you will not have to bend down to access the contents of this compartment. That is why this option is the most popular nowadays: most users often need access to the main volume of the refrigerator, and a freezer is required relatively rarely. Note that we are talking about classic freezers with doors; drawer freezers are placed in a separate category, described below.
— Bottom (retractable). Freezer with a bottom location, made in the form of a drawer. The general advantages of the bottom location are described above. And the retractable design provides added convenien
...ce for the user, relieving him of the need to make unnecessary movements: to access the contents, it is enough to pull out the drawer without having to open the door first. On the other hand, such freezers are more demanding on the quality of thermal insulation, which affects the cost of the entire refrigerator. In addition, the pull-out chamber is one common container, without division into levels, while such chambers are rarely provided for more than two — this limits the possibility of separating different types of products into different compartments of the freezer.
— Top. The top position of the freezer makes it easy to access the contents without having to bend over. On the other hand, you will most likely have to bend over to access the main compartment. So this layout option is not as common as the bottom freezer installation and is mainly in two categories of refrigerators. The first is individual models of classic layout or French Door layout (see "product type"); many of them have a large overall height, which partly compensates for the features of the top location of the freezer. The second variety is compact units of small volume in which the freezer is installed inside the main compartment and does not have its outer door. In such cases, the top setting is considered optimal for several technical reasons.
— Side. The traditional option for Side-by-side units (see "Product type"), which is practically not found in other types of refrigerators. Note that the side freezer in such cases does not necessarily occupy the entire height of the refrigerator — it can be combined, for example, with a fresh zone or a wine chamber. In some models, freezers with this arrangement can even be equipped with separate doors. Although usually all compartments on one side of the unit are still covered by one common door.
— No freezer. By definition, single-chamber models do not have a freezer compartment (see "Number of chambers"); at the same time, in this category, there are both compact and rather large and roomy refrigerators. You can also find two-chamber units without a freezer on the market — in them the main compartment is usually complemented by a clearly defined fresh zone, but there is only one door, common to both compartments. Another type of unit with this feature is display refrigerators (see "Product type").Freezer capacity
The capacity of the freezer installed in the refrigerator. Such a chamber is designed to store products at temperatures well below zero (on average -18 °C). Its capacity is related to the total capacity of the refrigerator (and the capacity of the main, refrigerating chamber). However, there is no strict dependence here — models with a similar volume of the refrigerating chamber can be equipped with freezers of different sizes.
When choosing by capacity, it is worth considering how much frozen food you plan to store at a time. Note that it is undesirable to fill the freezer completely — this negatively affects the efficiency of work. However, if this chamber is planned to be used only occasionally, and you do not plan to keep numerous products in it, you can not chase after the capacity: for such cases,
25 – 50 liters, or even
smaller capacities, are enough. In the smallest modern refrigerators, the freezer capacity
does not exceed 10 liters. And vice versa, very roomy freezers come across — for
176 – 200 liters and even
more. Such volumes are typical mainly for side-by-side and French door units (see "Product type"). However, they are also found in models of the classic two-chamber layout.
Freezer temperature
The operating temperature of the refrigerator freezer.
The generally accepted standard for freezers is actually -18°C. It allows you to effectively store pre-frozen foods, as well as freeze them (with certain precautions). At the same time, for most modern refrigerators, lower temperatures are claimed — at
-24 °C, and in some models even lower. However, such indicators are not always standard — in many units, they are achieved only in the fast freeze mode (see "Features"). This should be clarified separately. However, the temperature of the freezer below -18 °C means good freezing features.
In turn, chambers with more modest minimum temperatures — -12 °C, or even -6 °C — are only suitable for storing pre-frozen products; they are not suitable for freezing any significant amount of contents. However, there are very few refrigerators with such indicators on the market — mostly low-cost or outdated models.
To indicate the temperature of the freezer, markings in the form of asterisks (snowflakes) are often used, each of which means a decrease in temperature by 6 °C. For example, in models at -24 °C, you can find the designation * (***) — four asterisks, one of which is highlighted. This usually means that in the standard mode the freezer operates at -18 °C (three stars), and at another 6 °C (down to -24 °C) the temperature drops during fast freezing.
