The cooling devices are real power guzzlers. It is therefore worthwhile to take a closer look.
Do you know that even an approximately 5 mm thick layer of ice increases the power consumption of your freezer by 30%? Of course, the same applies to your freezers. Regular defrosting (twice a year) will help. If you defrost your fridge during the winter, you can use the cool outside temperatures to keep your food fresh.
If you quickly close the refrigerator door, you'll get a double effect. First, less moisture gets into the fridge. This reduces ice formation. Second, less energy has to be used to cool the invading hot air. Think about what food you want to take out and minimize the opening time of your refrigerator door.
In addition, a well filled refrigerator requires less energy. Liquids such as water, beer or milk store cooling energy. As a result, after opening the door, the desired temperature can be restored more quickly. Before foods are refrigerated, they should be packed to ensure that no moisture can get in.
Pay attention to the site of your cooling units. A freezer needs much less energy when placed in a cool room. Also, a refrigerator should never be placed next to a heater. In addition, many secondary fridges based in the cellar operate all year round, although they may only be needed in the summer.
