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.
No Frost
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.
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.
Storage compartments
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 w
...ork 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.Controls
Refrigerator control panel. To date, there are such options:
—
Rotary switches. While a rotary switch technically has the potential to be used for a wide range of functions, in practice, this variety is typically only found in basic models with limited functionality. In such cases, control is often done manually by turning a thermostat knob, with limited options for adjusting temperature, humidity, and other settings.
—
Push-buttons. CRefrigerators can have a control panel with classic buttons that offer various functionalities depending on the model. These functionalities can range from basic adjustments (similar to rotary switches) to fine-tuning of temperature and humidity, control of special modes, and more. Compared to rotary switches, push-buttons generally offer a wider range of possibilities.
—
Touch. Touch panels are a modern and stylish control option for refrigerators, which requires a light touch to operate. They are considered the most advanced type of control, providing convenient and extensive functionality. Touch panels are typically installed in premium models, where they add to the device's aesthetic appeal with a minimum of unnecessary protruding parts.
Energy consumption per year
The average amount of energy consumed by a refrigerator in a year of operation.
The given parameter is an estimated value and assumes that the refrigerator operates under stable conditions without sudden temperature changes, frequent door openings, and within its designated climate class (see below). Actual energy consumption may deviate slightly from the stated value. Despite this, it is a useful parameter that allows for a rough comparison of different models in terms of energy efficiency.
It should be noted that the energy consumption per year is often a more practical and convenient parameter than the energy consumption class (see above), which is a relative indicator of how efficient a refrigerator is compared to other models of similar size and features. The energy consumption per year, on the other hand, provides an estimate of the actual electricity cost when using a particular refrigerator. For instance, a small two-door refrigerator with an energy class of A can consume less energy per year than a large side-by-side refrigerator with a class of A+++, despite the fact that the latter is formally more energy-efficient than the former in terms of its energy class.
Climate class
This parameter describes the climate conditions for which a particular refrigerator model is designed. A more powerful cooling system and better thermal insulation are required for the refrigerator to operate efficiently in hot conditions compared to low air temperatures. If the refrigerator is not designed for the specific climate conditions it operates in, it may not function efficiently or may even fail.
—
SN (subnormal).Refrigerators of this class are intended for use in temperate climates with relatively low temperatures. They are designed to operate within a temperature range of +10°C to +32°C, which is slightly lower than class N. These refrigerators can be particularly useful in poorly insulated rooms where the temperature can drop below +16°C during the colder seasons.
—
N (normal). Models designed for moderate climate, with ambient temperature from +16 °C to +32 °C.
—
ST (subtropical). Although named after subtropical climates, these models are suitable for both subtropical and tropical climates with high humidity. They can operate within a temperature range of +18°C ... +38°C.
—
T (tropical). Units designed primarily for dry tropical climates. They operate at ambient temperatures from +18 °C to +43 °C.
to the development of refrigerators with combined climate classes and enhanc
...ed features. These models are characterized by both upper and lower classes, such as N-ST, indicating a wider operating range from the lower limit of the lower class to the upper limit of the upper one. For instance, N-ST corresponds to a temperature range of +16...+38 °C. Some models even combine all four classes, such as SN-T, which has an extended range of +10...+43 °C.
With climate change affecting many regions, the introduction of combined climate classes has become increasingly important. In some areas classified as temperate, summers have become hotter while winters remain cold, and a single climate class such as N may not provide adequate coverage for the required temperature range.Noise level
This parameter indicates the level of noise that the refrigerator produces while operating. A noise level of 40 decibels is similar to the average volume of human speech, 50 decibels is similar to the background noise in an office, and 80 decibels is similar to traffic noise. The lower the noise level of the refrigerator, the more comfortable it will be to use.
