New generation appliances can help reduce electricity consumption in the home significantly. Of course, it is unthinkable to immediately replace all existing devices with energy savings, but the gradual replacement of obsolete or outdated equipment can help improve the parameters of energy consumption in the home.
Energy saving equipment
Refrigerator
The first energy efficient appliances we saw could save a lot of money by reducing energy consumption at home. After all, this device works day and night, so it is better to choose it carefully. This is a refrigerator. The technological innovation of almost all manufacturers is the inverter motor. It is very quiet and allows you to control the power consumption of the device, avoiding peak usage. By maintaining a constant and even temperature, it is possible to optimize energy consumption and increase the efficiency of the refrigerator.
Several manufacturers have developed technologies that allow you to better preserve food by differentiating ventilation in different compartments. The release of active oxygen in modern models prevents the formation of bacteria. The energy -saving refrigerator made by the South Korean company, in turn, uses insulating panels more efficiently. They are much thinner than the material used just a few years ago. This means modern refrigerators have become more energy efficient. More space for food, but less energy consumption to cool it. Recently, American researchers placed refrigerators accordingly in a leading position in the ranking of energy saving. This energy saving appliance uses the same as a 20W lamp. These results are achieved thanks to effective insulation, gaskets, new variable speed compressors and, again, the shape and position of the evaporator and condenser.
The results of another study conducted in the United States may convince even the most unsure to change the refrigerator. In 12 years after buying a new model, the reduction in energy costs over an old appliance can be several hundred dollars. The most energy efficient model is the model that has a freezer at the top of the refrigerator. At the same time, side-by-side refrigerators have the worst energy efficiency indicators.
Dishwasher
From a technological point of view, modern dishwashers not only use less energy, but also less water, and the adjustable basket allows you to optimize the load. German manufacturers also use the properties of natural zeolites, minerals that absorb moisture during washing and release it as vapor during drying, making the last step of the cycle faster and more efficient.
Washing machine
Modern washing machines provide different washing cycles to reduce water and detergent consumption. Extensive research has shown that the cleaning process does not depend on the temperature of the water and detergent used, but is a result of the mechanical action of the drum. In this regard, new solutions have emerged, for example, a washing machine developed by the company introduces air bubbles into the drum, which allows detergent to penetrate better into the fabric and wash well even in cold water.
Induction cooker
Induction hobs are becoming increasingly popular, even among the line of energy -saving equipment. They cook food by creating an electromagnetic field that only heats the bottom of the cookware. As a result, there is no loss of energy. You save money, since the efficiency of this device reaches 95%, while in a conventional gas stove there are leaks of the order of 30-60%.
Vacuum cleaner
How do you convert watts to a useful working vacuum cleaner? Not much if the vacuum system is inefficient. The only thing you can tell by looking at the watts shown on the energy label is the energy absorption. But what if all this energy is used inefficiently? New energy -saving appliances provide a good guarantee. Vacuum cleaner models with cyclone technology have the advantage of not having a dust bag. The suction power remains unchanged, from which the energy efficiency of the apparatus benefits.
Energy efficiency label
After making sure that the appliance can help save energy in the house, all that remains is to choose the right model. There are a lot of offers, and it’s not that easy to navigate. The first thing to do is pay attention to the energy efficiency label, which gives a clear picture of energy consumption.
The horizontal arrow at the top indicates the energy efficiency class, which can range from A +++ (best) to G (worst). The color of the arrow also indicates the energy efficiency level of the equipment: from red for high energy consumption classes to dark green for the most energy efficient equipment. Arrows show energy consumption in kWh per year based on laboratory tests, i. e. under optimal conditions. Knowing the cost of electricity, you can easily determine the annual cost of electricity, which obviously also depends on the mode of use of the device.
