Total capacity
The total volume of a refrigerator is the sum of the volumes of all its compartments, which can vary in specific capacity between different models. It's important to consider this when choosing a refrigerator.
A larger volume for a refrigerator can be beneficial for accommodating more food, but it can also increase the price and size of the appliance. This is especially important to consider if you plan to build the refrigerator into a specific space.
Number of cooling circuits
The circuit in a refrigerator refers to the cooling system connected to the compressor. Typically, the number of circuits corresponds to the number of compressors, but some models have
two cooling circuits are connected to a single compressor for the refrigerator and freezer. While a dual-circuit refrigerator with one compressor cannot turn off one compartment while keeping the other functional, it allows for separate temperature control.
Refrigerator capacity
The refrigerating compartment is designed for storage of products that do not require freezing, i.e. cooling down to temperatures below zero. The temperature range inside varies from +2 to +10. In almost all modern refrigerators, it is this compartment that has the largest volume.
To ensure optimal performance and food quality, it's important to choose the appropriate volume for the refrigerating compartment based on your actual food storage needs and how often you replenish your supplies. Overfilling the compartment can have a negative impact on both the refrigerator's performance and the quality of the stored food.
For singles or couples, a refrigerating compartment of up to 200 liters is enough, while families or those who stock up on food should opt for models with up to 400 liters. Vertical refrigerators with separate freezer access are suitable for those who need moderate storage space, while side-by-side refrigerators with their typically larger volumes are a good option for those who require even more space and have ample free space.
Number of shelves
The amount of shelves in a refrigerator determines the division of space within the refrigeration compartment. Larger refrigeration compartments generally have more shelves, but there are also various configurations available even within the same volume (
3 shelves,
4 shelves,
5 shelves and more). It is worth considering that they are mostly removable, which allows you to adjust the height of the shelf. And if necessary, you can buy more.
Foldable shelf
Having
foldable shelves in the refrigerator compartment is useful for accommodating large-sized utensils, tall or bulky products, and dishes. This feature can be implemented in different ways, such as folding the halves of the shelf up or down, using a sliding shelf structure, etc. Some shelves can even be folded in multiple stages, first in half and then leaning against the back wall of the refrigerator compartment.
Fast cooling
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.
Freezer capacity
The primary function of the freezer is to store food in a state of deep freeze, which helps preserve perishable products such as meat, vegetables, fruits, etc. for extended periods of time. The necessary volume of the freezer depends on the planned amount of food to be stored and the length of time it will be stored. A larger freezer is particularly useful if you plan to store food for several months.
A compact freezer is relevant for short-term storage (for a day or two) or for seasonal devices (for example, in the village). It is best to ensure that the freezer is not overloaded and has enough space for proper circulation of air to maintain the desired temperature.
Number of freezer drawers
The quantity of freezer drawers in a refrigerator affects the optimal organization of frozen foods. A larger number of drawers allows for better separation of different types of frozen products. However, in the majority of standard two-compartment refrigerators, there are typically
three freezer drawers.
Freezer temperature
The lowest temperature provided by a refrigerator freezer.
The lower the freezer temperature indicator, the more advanced the freezer is considered to be, and the better it is suited for long-term food storage with wider capabilities. It's important to note that the standard operating temperature for a fully functional freezer is -18 °C, which is suitable for both storing and freezing pre-frozen foods. Some refrigerators are designed with a temperature indicator of -24 °C, but this is mainly achieved through the quick freezing mode (see "Functions"), and the standard operating temperature is still -18 °C. However, if you plan to freeze food frequently and store it for extended periods, it's better to choose a model with a temperature of -24 °C and consider the freezing power as well.
Less expensive refrigerators have a less advanced freezer with a modest minimum temperature of -12°C or even -6°C, which is only suitable for storing pre-frozen foods, not for freezing fresh food. Although they are much more affordable.
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, the mentioned -18 °C will correspond to 3 asterisks (***).
