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 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.
Autonomy time
Refrigerators with good thermal insulation can maintain low temperatures inside for a significant amount of time even if there is a power outage. This period of time is known as the "keep cold time," during which the refrigerator can preserve perishable food items. A longer keep cold time indicates better thermal insulation, making the refrigerator more suitable for areas where power outages are common.
Energy class (new)
The energy efficiency of a refrigerator is measured by a parameter classified from A to G, with A being the most efficient. Originally, only up to class A was available until newer, more efficient models were introduced and labeled as A+, A++, and A+++. However, in March 2021, manufacturers reverted to the original labeling system from G to A to avoid creating more pluses. This means that modern models will have the new labeling system, while older ones will maintain their original markings.
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.
Noise class
Allows people to decode the values of the noise level in decibels. It is marked in Latin letters like other classes, where A is the quietest class of refrigerators.
