Refrigerators are the topmost consumer of electricity among all homeappliances. That is because refrigerators use complex energy systems that generate and absorb heat to freeze or make cold its contents.
Refrigerators are also the most basic among all home appliances. It is principally used to store food and beverages to keep them cold. Theseappliances also naturally preserve food items stored within.
When buying refrigerators, you should look for the energy efficient ones. Reliable and popular appliance brands usually offer refrigerators that aren't just sophisticated and highly functional, but also energy efficient.
Take note that size matters when you are assessing energy consumption of refrigerators. The bigger the refrigerator, the more energy it uses. Two-door and single door refrigerators also differ in the amount of energy consumption. Two-door refrigerators are deemed to be more economical and energy efficient because freezer temperatures won't be disrupted when you open the door to get and store food.
There are still simple tips you should consider if you aim to save on costs while using the refrigerator.
Don't store hot food or beverages in the fridge. Refrigerators work by absorbing heat in stored food and conducting such heat to its compressor. This temperature conduction process makes up for energy consumption.
Clean the condenser coils of your refrigerator regularly. Such condenser coils are usually located behind or underneath the fridge.
Always make sure that refrigerator seals and freezer doors are fitting tightly. This will ensure that there won't be unnecessary leakage of air from inside the fridge.
Don't use a separate freezer for food. Doing so would be wasteful unless that separate freezer is constantly kept full. Remember that it will take less power to run a full freezer than when it is half empty.
