Eight ways to save electricity when using a refrigerator to help reduce your monthly electricity bill by 25%
Refrigerator is an appliance that every home has. Being turned on all year round, the refrigerator is very power-hungry.
Saving electricity when using a refrigerator helps you reduce your electricity bill. Here are some ways to save electricity when using a refrigerator that not everyone knows.
1. The best temperature setting at 7-8 degrees Celsius will use less electricity
When you just bought a refrigerator, you should prepare a thermometer, put it in a compartment in the refrigerator compartment. After placing the food and then starting to adjust the cold, it is recommended to adjust 2-3 times to gradually reach the best temperature (usually 7-8 degrees Celsius). This is the most suitable temperature. Using a refrigerator at a temperature below 5 degrees Celsius will consume more than 1kW. If it is a refrigerator with 2 doors, the freezing chamber temperature at -18 degrees Celsius is enough for the water to freeze. If you use -18 degrees Celsius instead of -22 degrees Celsius, you can save about 25% of electricity every month.
2. Add foam plastic to the freezer compartment
When the food to be kept takes up only a small area of the cold chamber, you can bring the full pieces of foam plastic into the freezer, from 1-2 compartments. The thermal conductivity of foam plastic is very poor, it hardly sucks the cold air inside the cabinet. Following the above method, the initial volume of fridge is reduced, making the working time of the refrigeration unit to be emptied short, of course, electricity will be saved.
3. Use a piece of nylon inside as a curtain to prevent the convection between the two airflows inside and outside the refrigerator
Every time the refrigerator door is opened to take out food, the cold air inside the refrigerator will convection very quickly with the hot air outside the refrigerator, causing the temperature inside the refrigerator to rise, thereby consuming electricity faster. You can use a piece of inner plastic, slightly larger than the door of the cooler compartment, as a curtain to prevent convection between the two air flows in and out. Doing so both saves money and protects the machine.
4. The refrigerator needs to be placed in a ventilated, cool place
Because, the higher the space temperature, the more heat is transferred to the cabinet, the slower the heat dissipation, the more electricity is lost. Try to limit the number of times the refrigerator door is opened. The more open, the more power loss will be. To allow air to circulate around the refrigerator and to prevent moisture, you can place the refrigerator more than 5cm above the ground.
5. Do not overfill the refrigerator with food
It is necessary to leave a gap between the foods so that the cold air can convection, the amount of electricity loss will be reduced.
6. Hot water, hot vegetables, hot rice must be completely cooled before putting in the refrigerator
If you put it in while it is still hot, it will make the temperature in the refrigerator rise too quickly, causing more electricity to be consumed. Use metal containers instead of plastic ones. Currently on the market sell a lot of specialized plastic containers for refrigerators. This type of box has the advantage of being light and clean and the price is cheap because its cold conductivity is very poor, so the cooling time will be longer. Using aluminum or stainless steel containers will shorten the cooling time and save electricity.
7. When buying a refrigerator, choose a cabinet with a light color because dark colors absorb more heat
In addition, the market now offers many types of cabinets with very good power-saving capabilities. To “identify” energy saving refrigerator, the buyer must rely on the technology adopted by the manufacturer or their more convenient operational features. This information is provided in full on the product’s surface or the manufacturer’s instruction sheet.
8. Regularly clean the refrigerator
Dirt clings and accumulates on the surface of the outdoor unit, indoor unit, filter, etc., which interferes with heat exchange and slows down the cooling of the machine. With dust filter, clean about once a month. You can make it yourself, take it off and wash it with a brush and soap. The water compartment created by the cooling process (usually located at the bottom, back of the refrigerator) also needs to be emptied regularly. This water often has dirt, even dead insects in the house. If the water is too full, it can cause overflow, short circuit or cause electric leakage without the owner’s knowledge, thus consuming more electricity.
