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.

The presence of the No Frost system in one or more refrigerator compartments.

This system prevents the formation of frost on the walls of the compartment, as happens in models without No Frost. No Frost is a technology used in refrigerators that removes moisture from the air inside to prevent frost buildup. It works by condensing water vapor and evaporating it outside the refrigerator. However, this feature can cause food to dry out more quickly, so proper packaging is essential.

In modern refrigerators, No Frost can be provided both in the refrigerator and in the freezer, and often in both compartments at once. When deciding whether to choose a No Frost refrigerator, it is important to weigh the benefits of not having to defrost against the possible downside of faster drying of food products. This feature is more advantageous for the freezer, as the benefits of No Frost are more significant at sub-zero temperatures and the disadvantages are less noticeable.

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.

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.

Apart from shelves, there are several additional compartments in a refrigerator, including a a freshness zone, a humidity zone, a multi-zone and a shelf for bottles.

— Freshness zone.It is a special compartment in a refrigerator designed for storing fresh products for an extended period. The temperature in this zone is slightly lower than the refrigerating chamber, typically around zero degrees, earning it the nickname "zero chamber". Such conditions help to preserve the freshness of products for up to 3-4 days. However, it's important to note that the temperature in the zero chamber may vary depending on the refrigerator model, ranging from 0 °C to +1...3 °C, which can impact the preservation of stored products.

— Humidity zone. Another specialized compartment, similar to the freshness zone, is designed to preserve the freshness of food items for an extended period. However, this compartment maintains high humidity at the same temperature as the rest of the refrigerator, which prevents the products from drying out. This feature is especially important for refrigerators with No Frost systems, which tend to blow moisture out of the refrigerator, leading to quicker drying of the contents.

— Multi-zone. This compartment in a refrigerator combines several functions of different compartments, such as the...ability to work as a refrigerator or a freezer, along with other specific features like quickly cooling drinks, slow defrosting, and cooling hot dishes. Modern refrigerators offer more extensive capabilities with specific features, making the multi-zone compartment a valuable addition. Some models have the entire freezer performing the function of a multi-zone chamber, but most models have a separate compartment for it. The presence of a multi-zone compartment significantly expands the capabilities of a refrigerator.

— Shelf for bottles. It is a hanging accessory, typically in the form of a lattice, that is installed under a shelf in the refrigerator. It allows bottles to be stored horizontally, which saves space in the refrigerator while keeping them organized.

The volume of the zero chamber provided in the refrigerator. Such a chamber is also referred to as a "freshness zone"; see "Functions" for more details.

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.

In refrigerators with dynamic air cooling, the air inside the working compartment moves not due to the temperature difference, but due to the operation of the built-in fan. This ensures uniform distribution of cold air and the same temperature throughout the volume.

The location of the freezer in the refrigerator.

— Top. One of the standard options for vertical refrigerators. It is consideredless practical than the bottom location. In such models, the main compartment is situated quite low, requiring users to bend over to access it. However, for individuals who are shorter in height, this feature may actually be advantageous rather than a drawback.
It's worth mentioning that the top location is commonly found in compact refrigerators where the freezer doesn't have its own external door, and one needs to open the main compartment before accessing it.

— Bottom. The lower position is a classic and widely used configuration for vertical refrigerators, as well as in side-by-side models to a lesser extent. The main advantage of this setup is that the freezer compartment is accessed less frequently than the main compartment, and placing it at the bottom reduces the need for users to frequently bend over to reach it.

— Side. Side-by-side refrigerators typically have the freezer located on one side of the unit, with the other side dedicated to the main compartment. The freezer may take up the entire half of the refrigerator, or be combined with other compartments, such as a freshness zone or wine storage. These models are often larger in capacity and size.

— Absence.... The absence of a freezer is a common feature in some refrigerators, especially in small and affordable single-compartment models. However, it is not limited to compact designs, as larger refrigerators with a volume of 300 liters or more may also be freezer-free. Additionally, some two-compartment models reserve the second compartment for a freshness zone instead of a freezer. Lastly, refrigerated display cases, which are used for commercial purposes, do not include freezers (see "Type").
