The refrigerator works continuously for a long time, which is a big power consumer at home! Today, let's tell you how to choose a refrigerator with high energy-saving efficiency and how to make it more energy-saving and power-saving.
Energy saving refrigerator purchase tips:
1. The lower the energy consumption, the more energy-saving. The energy label of refrigerator is evaluated according to its energy efficiency. The lower the energy consumption is, the higher the energy-saving benefit is, and the more money is saved.
2. Buy the right refrigerator. Choose a refrigerator suitable for your own needs, such as a small family only need a small refrigerator. Because the price of small refrigerators is lower, and it also saves power. In addition, the power consumption of the refrigerator can be known from the energy label. The lower the number of kilowatt hours (KWH), the more economical the operating cost of the refrigerator.
3. The refrigeration and freezer door separation, as well as smaller freezers, will save electricity. There are many different styles of single door or multi door refrigerators on the market, which can be considered according to your own habits and living area.
How to use refrigerator
1. Store food properly
Keep the refrigerator "always full" state, reduce air to refrigeration, so as to improve the efficiency of energy saving. But the refrigerator filled with excessive food, but will hinder the air circulation, causing the refrigerator does not refrigerate. On the contrary, too little food can't be stored. As the heat capacity becomes smaller, the start-up and shutdown time of the compressor is shortened, resulting in an increase in the accumulated power consumption of the refrigerator.
There should be a space between the stored food, so that the cold air convection, temperature uniformity, the use of small packaging can reduce the time of cold penetration, save electricity, and convenient access.
The liquid food such as soup or drink in the refrigerator must be covered, and the food should also be sealed with fresh-keeping box or fresh-keeping paper. This can not only keep the food from being dry and tasteful due to the loss of water, but also cause the compressor of the refrigerator to work harder due to the release of water.
2. Knowledge of placing objects
Due to the high temperature of the meat and fish just bought, if they are directly put into the freezer, the original temperature in the refrigerator will be affected and the load of the refrigerator compressor will be increased. Therefore, the meat and fish can be put into the freezer first to cool down, and then to the freezer.
The food in the freezer can be packaged in plastic bags or plastic film, which can avoid drying on the one hand, and moisture frost on the other hand. If the frost hanging on the freezer is too thick, the cooling effect will be weakened, and the power consumption will also be consumed.
Making ice and cold drinks is best arranged at night. Because of the lower temperature at night, it is conducive to the condenser heat dissipation, and less open the freezer to store and store food at night, so the working time of the compressor is shorter, and the electric energy is saved.
The waste heat of the pot, if put into the refrigerator immediately, will also affect the original temperature in the refrigerator, increase the number of compressor operation. It is suggested that the hot pot be put into the water tank, and then put into the refrigerator.
Pay attention to the capacity of the refrigerator, the best thing is not to place more than eight points full, and most importantly, do not block the air outlet of the refrigerator, so as not to consume unnecessary power. In addition, the square packaging of food is not full, to ensure that food should leave a certain gap between each other, in order to facilitate the circulation of cold air in the refrigerator.
3. Proper maintenance of refrigerator
Proper maintenance can prolong the life of refrigerator.
Regularly clean the dust on the ventilation grille on the back of the refrigerator. The ventilation grille is clean and the air is in circulation. The compressor can operate smoothly.
Defrost regularly. If the frosting thickness of the freezer is more than 4 to 6 mm, it will reduce the efficiency of energy saving and lead to a waste of money. For refrigerators without intelligent defrosting function, because the heat transfer of frost layer is slower than that of metal, the refrigeration effect of evaporator will be hindered and the power consumption will be increased. Therefore, the refrigerator without automatic defrosting should be defrosted manually in time when the frosting thickness is more than 4 to 6 mm on the evaporator.
Make sure the refrigerator doesn't "leak" through the gap in the door. If the cold air is emitted from the refrigerator, the compressor should work twice to cool. How to know the "air leakage" of refrigerator? Just clip a banknote between the door and the refrigerator. If the bill falls off quickly, it means that the adhesive tape on the refrigerator door is loose and needs to be replaced.
4. Correct temperature of refrigerator
The temperature of refrigerator and freezer should not be too cold. The temperature of refrigerator should be maintained between 2.7 ℃ and 4.5 ℃, while that of freezer should be below - 15 ℃.
Frozen food should be put into the freezer to melt before eating, which can reduce the temperature of the freezer and save electricity. The hot food should be cooled to room temperature and then put into the refrigerator, so as to avoid the rapid rise of temperature in the refrigerator, and increase the frost thickness on the surface of the evaporator, which will lead to the increase of working time and power consumption of the compressor.
In addition, the number and time of opening doors should be reduced as much as possible when storing and storing food. Because open the door once, the cold air disperses, the compressor will have to run for more than ten minutes to recover the refrigeration temperature.
5. The correct position of refrigerator
The place where the refrigerator is placed is often limited by the electric plug and water pipe. It is necessary to ensure that the place of placement is air circulation in order to operate more effectively. If the refrigerator is placed between the cabinets, it is necessary to ensure that the air circulation is not obstructed.
The refrigerator is best not to be placed near the window, stove or electric stove and other heat sources. The direct sunlight and the heat of the stove will cause the refrigerator to consume more energy to cool. It is best to place it in the "coldest" corner of the kitchen.
