When choosing a refrigerator, many factors can influence a buyer’s decision. A refrigerator is not just a household appliance, but an important part of the kitchen space that plays a key role in food storage and directly affects the quality of food and convenience in everyday life. The right choice determines not only the comfort of use, but also the long-term energy costs and environmental impact.
Choosing the right class of refrigerator is a balancing act between current needs, available budget and future prospects. This decision requires careful attention and consideration of all possible aspects in order to fulfil both immediate and long-term needs.
Table of refrigerator energy consumption classes
This table shows the energy consumption classes of refrigerators, which are usually labelled with letters and give an indication of how energy efficient the appliance is:
| Energy class | Energy efficiency | Approximate energy consumption per year (kWh) |
| A+++ | Highest | Less than 150 kWh |
| A++ | Very high | 150-200 kWh |
| A+ | High | 200-250 kWh |
| A | A good one | 250-300 kWh |
| B | Moderate | 300-350 kWh |
| C | Below average | 350-400 kWh |
| D | Low | 400-450 kWh |
| E and below | Very low | More than 450 kWh |
Energy Classes allow consumers to easily compare different refrigerator models based on their ability to save energy. The higher the class (e.g. A+++), the less electricity the refrigerator consumes, making it more environmentally friendly and economical in the long run.
Comparative table of key aspects of different classes of refrigerators
| Criterion | Importance for choosing a refrigerator |
| Energy efficiency | High class (A+++, A++, A+) provides energy savings but may be more expensive to purchase. Low class (B, C, D) is more economical to purchase but more costly to operate. |
| Capacity | Large capacity is suitable for large families or stocking up on groceries, small capacity is for singles or small families. |
| Functionality | Additional features (No Frost, fast freezing, special compartments) increase usability but can increase cost. |
| Design | Style, colour and the ability to blend in can be important to a harmonious kitchen design. |
| Cost | High cost is often associated with better features, but budget models may be adequate for basic needs. |
Additional features of energy-efficient refrigerators
When choosing an energy efficient refrigerator, in addition to the standard energy efficiency class (A+++, A++, A+, A+, etc.), there are a number of additional criteria to consider:
Cooling technology: Modern refrigerators can utilise various cooling technologies such as inverter compressors, which are more efficient and economical than traditional compressors. Inverter models adjust their operation according to need, which reduces energy consumption.
Size and capacity: It is important to choose a refrigerator that is the right size for your household’s needs. A large refrigerator that is not full will use more energy than necessary. On the other hand, an overfilled small refrigerator will also be inefficient.
Temperature control: Precise electronic temperature control helps maintain optimum conditions for food storage and reduces energy consumption.
Eco or Holiday mode: Some models are equipped with special energy-saving modes that reduce energy consumption when you are away from home or at minimum load.
Door seals: Quality door seals provide a reliable seal, preventing cold air leakage and consequently reducing energy consumption.
Anti-condensation technologies: The presence of technologies that prevent the formation of condensation and frost also helps to reduce energy consumption.
Energy-saving lighting: Using LED lamps instead of traditional light bulbs helps to reduce energy consumption.
Insulation materials: The high quality insulation of the refrigerator helps to maintain low temperatures inside while minimising energy consumption.
Certifications and ratings: Having energy efficiency certifications, such as Energy Star or equivalent, is an additional indicator of a refrigerator’s efficiency.
With these additional criteria in mind, you can choose a refrigerator that is not only energy efficient, but also best suited to your needs and preferences.
