Comparison Snaige RF27SM-S10021 white vs Snaige RF360-1801AA white

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.

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 number of shelves supplied with the refrigerator. In this case, only shelves placed inside the main (refrigeration) chamber are taken into account. And closed drawers, which are usually at the bottom, are not considered shelves.

In general, this amount depends on the volume: the more spacious the refrigeration compartment, the more shelves are usually provided in the kit. At the same time, there is no strict dependence here, and refrigerators of similar capacity can be equipped with a different number of shelves. As for specific options, the most modest models come with 1 – 2 shelves, 3 shelves and 4 shelves can be called an average, and more are found in some units.

In most modern refrigerators the shelves are removable. In addition, they can be installed at different levels. In this case, it is not necessary to use the entire set: for example, if it is planned to place tall objects inside, one of the shelves can be removed, creating a vast space. And vice versa: if necessary, you can, usually, buy additional shelves. So the number of shelves in the kit only allows you to evaluate the overall possibilities for organizing space in the refrigerator. How to use these features depends on the user.

Indoor lighting based on built-in light-emitting diodes (LED) has several advantages over more traditional bulbs. Firstly, due to its high efficiency, it gives excellent brightness with low power consumption and also generates almost no heat. Secondly, small LED lamps can be evenly distributed along the walls of the chamber, providing bright illumination of the entire volume of the refrigerator. The disadvantages of such lighting can only be attributed to a certain difficulty in repair and replacement. However, modern LEDs are quite durable.

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.

The autonomy time provided by the refrigerator when the power is turned off.

Often, this parameter describes the capabilities of the freezer. In such cases, the autonomy time is indicated as the time during which, at an outside temperature of +25 °C, the temperature in the filled freezer does not rise above -9 °C (this level is considered critical for the storage of frozen foods). Accordingly, the actual autonomy time may differ from the claimed one — depending on the ambient temperature, the frequency of opening the refrigerator, etc. However, this parameter describes the quality of thermal insulation quite accurately, and it is possible to evaluate different models and compare them with each other.

Also, autonomy time can be given for models without freezers: in such cases, we are talking about the time during which the temperature in the refrigerator compartment remains at an acceptable level under approximately the same conditions.

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.

Forced freezing mode, in which the temperature inside the freezer falls below the standard level for a short time. This mode is useful when loading a large amount of unfrozen food into the freezer. The fact is that the heat from these products can lead to an increase in the temperature inside. The fast freeze feature allows you to compensate for this phenomenon and avoid violations of the temperature regime. However, fast freeze, usually, needs to be turned on a few hours before loading new food, and the freezer is usually not designed for permanent operation in this mode, after a while, it needs to be switched to normal mode (in some refrigerators this is done automatically) .
We also emphasize that some units provide separate boxes or zones of “fast freezing”, with a lower temperature. Such equipment is not considered for the fast freeze feature since it has slightly different specifics of work.

The type of controls for refrigerators is indicated primarily by the type of control panel. Often its location is also taken into account. According to these criteria, nowadays, the following options are distinguished: rotary knobs, internal push-buttons, external push-buttons, internal touch controls and external touch controls. Here are the features of each of these options:

— Rotary knobs. Control using rotary knobs. Such knobs are traditionally installed inside the refrigerator, so in this case, the location is not specified. In general, this is the simplest and most inexpensive option used in units of the appropriate level. Most often, there is only one rotary knob; it is directly connected to the thermostat and regulates only the temperature inside the refrigerator (and even then very approximately). However, even this is often quite enough — especially if the refrigerator is operated in more or less constant temperature conditions (for example, in a home or office kitchen). In many cases, the matter is limited to choosing a more or less suitable knob position once and then not touching the settings at all. In addition, the unambiguous advantages of this type of control are reliability and ease of repair.

— Internal push-buttons. Push-buttons are generally considered more advanced th...an rotary knobs. The specific functionality of refrigerators with such control may be different, but among them, models with additional functions and the ability to fine-tune the temperature (and sometimes even humidity) are noticeably more common. As for the interior layout, it allows you to hide the panel behind the refrigerator door, providing a neat appearance with a minimum of protruding parts. And if the door has a child lock, in this case, it also performs the function of protecting against children. However, to access the controls you have to open the refrigerator — but this moment is generally not critical: such access is not needed so often, and changing settings does not take much time.

— External push-buttons. Like the internal push-buttons (see above), such controls are typical mainly for fairly advanced models (although exceptions are possible). And the external location is convenient because you do not need to open the door to access the settings. On the other hand, the real need for such an arrangement is not so often, and push-buttons must also fit into the overall design of the unit (which is not always possible to do in the best way). As a result, the external version of push-button controls is much less common than the internal one.

— Internal touch controls. Internal touch controls are considered the next step in the development of controls, after buttons. So, they look stylish and technologically advanced, they do not need to be pressed hard (just touched), and there are no protruding parts, corners and cracks on the surface of the panel, which simplifies cleaning from dirt. Accordingly, the presence of touch controls is typical mainly for refrigerators of the middle and top levels. It costs a little more than a push-button one, but this is imperceptible against the background of the total price of the units. But specifically, the internal location is much less common than the external one. It is because there is no need to hide the touch sensors behind the door — they can be easily fit into the external design of the refrigerator.

— External touch controls. The general features of touch controls are described above. And external touch panels in refrigerators are used much more often than internal ones: such panels can be given almost any appearance, optimally fitting them into the design of the refrigerator. Besides, placing them outside allows you not to open the door again to access the settings.
