 The importance of energy efficiency to choose your appliances |  Technology with Purpose

Home appliances account for more than 60% of electricity consumption in the residential sector, according to Deloitte. But each appliance can have a different impact on your electricity bill. The refrigerator is the appliance that consumes the most (30.6%). They are followed by the television (12.2%), the washing machine (11.8%), the electric oven (8.3%) and the dishwasher (6.1%). To save energy, the Organization of Consumers and Users (OCU) advises opting for efficient appliances: “By purchasing them, you will cut your electricity bill from day one.”

Going from a refrigerator with energy certification G to one with A means a reduction in consumption of more than 50%, according to Deloitte. By replacing an old one with a more efficient one, it is possible to save around 900 euros over its useful life, as indicated by the Andalusian Energy Agency.

But, how can the consumer know the efficiency of each model? To that end, the so-called energy efficiency label, a classification system that began to be used in some appliances more than 25 years ago. Currently, it is mandatory in refrigerators, freezers, washing machines, dryers, dishwashers, electric ovens or air conditioners. Its format has varied in recent decades. Until 2021 the labeling was based on a few letters – from A to D. One, two or three + symbols could be added to the letter A to indicate greater efficiency. But on March 1, 2021, in washers and dryers, dishwashers and refrigerators, a change occurred: the + symbol was eliminated, so that now efficiency is measured only by letters and colors.

The new labels use classifications ranging from the letter A to G (following the order of the alphabet). The devices marked with the letter G and the color red are the least efficient, while the products with the letter A and green are the best energy.

The consumption of household appliances is determined by three parameters, explains José Luis Sancha, an electrical engineer from the Higher Technical School of Engineers of ICAI: power, operating time and efficiency. “The refrigerator does not have a great power, but it is connected 24 hours a day, so, in the end, it is the appliance that consumes the most,” he explains. Others, such as the oven, the clothes dryer, the hair dryer and the iron, although they are more powerful electrical appliances, “work sporadically and therefore their energy consumption in the home is lower”. “Within each particular appliance, the higher the efficiency, the lower the consumption,” he adds.

Know the degree of efficiency

But then, how important is it to look at the labels when purchasing one of these devices? “Efficiency should be the most important factor when buying an appliance,” says Sancha. The expert recommends choosing appliances with an energy rating A. In addition, he underlines the importance of “choosing those appliances with adequate power, neither greater nor less than necessary.” Once at home, he advises “to use them depending on the specific situation”. In other words, choose the appropriate program for the washing machine or the appropriate temperature for the oven or refrigerator. Maintaining them properly can also help “save energy and extend their life.”

QuickDriveTM technology enables Samsung washing machines to save up to 50% in washing time and up to 20% in energy consumption.

Multiple Samsung appliances have a green rating, and include a QR code – required on all new labels – to get more accurate information about the appliance’s consumption. When scanning with a smartphoneMore detailed information can be found through the European Product Database for Energy Labeling (EPREL). Depending on the appliance, not only is electricity consumption reported, but also data is provided on the water used per wash cycle, storage capacity or noise, among others.

Technology that helps save

Samsung has focused on achieving such energy efficiency with low-power, high-quality products. Their refrigerators use Digital Inverter technology in the compressor, which allows them to use 50% less energy and, therefore, leads to economic savings. In addition, it makes the refrigerator very quiet and has a greater durability, with a 10-year guarantee. Metal Cooling technology can also help save energy. It is a metal plate inside the refrigerator that reduces the dispersion of cold, thus helping to preserve and restore the original temperature, regardless of how many times you open and close the door.

The Korean firm not only thinks about saving electricity but also optimizing space. its SpaceMax ™ technology Achieve more indoor capacity with the same outdoor space and greater energy efficiency without compromising performance. The Digital Inverter system is also present in the motors of Samsung washing machines so that the user can save energy, extend the life of the washing machine and make laundry much quieter. They also have a 10-year warranty.

But if Samsung washing machines are characterized by something, it is because they are equipped with QuickDrive ™ technology, which allows you to save up to 50% in washing time and up to 20% in energy consumption thanks to the double rotation of the drum. This system takes care of the clothes and allows “to save 50% in energy compared to conventional washing machines” and to do the laundry without having to use hot water. Being faster is more effective. But this is not all because thanks to its EcoBubble ™ technology designed to achieve excellent results in cold water “the water with detergent mixes with air before entering the drum, generating a layer of bubbles that penetrates faster in the garments and it protects them from friction ”, they indicate from the company.

In addition, Samsung washing machines are equipped with what the company calls Auto Doser +, a system that serves to save detergent and time in having to replenish it with each wash. Thanks to its four sensors, the dispenser automatically adjusts the amount of detergent, fabric softener and water, as well as the duration of the wash cycle, based on the amount of laundry and level of dirt. To eliminate practically all the allergens and bacteria impregnated in the clothes, these washers have a specific steam program that operates at the end of the main wash cycle.

The SmartThings ™ app allows you to schedule the wash at the desired time and, thanks to artificial intelligence, suggests the most efficient cycle for each wash. This application is also very useful with the South Korean brand dryers: it suggests programs based on the laundry and offers advice based on the user’s needs.

On the other hand, Samsung dryers also stand out for their heat pump technology, which offers energy-efficient clothes drying at a reduced cost, since they consume much less energy than conventional dryers. These appliances have a function that remembers drying habits and suggests programs depending on the laundry.

These advancements confirm once again the importance of technology in helping to become more energy efficient. A good example of this are the innovations incorporated by Samsung in each of its products, which allow the user to reduce energy consumption to be more sustainable while optimizing the space in their refrigerator or saving time and money with each wash or drying.
