The main causes of frosting in refrigerators are as follows:
Moisture inside the refrigerator. The moisture inside the refrigerator comes from the moisture of the food, the moisture of the air, and the drain pipe of the refrigerator. When the refrigerator is running, this moisture will condense into dew drops on the inside of the refrigerator and then form frost on the refrigeration parts of the refrigerator.
The number of times the refrigerator opens and closes. The more times the refrigerator opens and closes, the greater the temperature difference between the inside and outside of the refrigerator, the more moisture inside the refrigerator, and the faster the refrigerator frosts.
The temperature setting of the refrigerator. The lower the temperature setting of the refrigerator, the greater the cooling capacity of the refrigerator and the faster the freezer will frost.
The cleanliness of the refrigerator. The worse the cleanliness of the refrigerator, the more dust inside the refrigerator and the faster the refrigerator will frost.
Frosting in the refrigerator is a very troublesome problem, so it is best to prevent frosting in the refrigerator at the source and reduce the frequency and difficulty of de-icing. We can do a good job of prevention from the following aspects:
Choose an air-cooled refrigerator. An air-cooled refrigerator is a frost-free refrigerator that evenly feeds cold air into all corners of the refrigerator through a fan, so that the inside of the refrigerator remains dry and not prone to frosting. The advantages of air-cooled refrigerators are easy to defrost, good refrigeration effect, low noise, and the disadvantages are higher and higher power consumption. There are many brands of air-cooled refrigerators on the market, such as Haier, Midea, Siemens, etc., and you can choose the right model according to your needs and budget.
Control the number of times the refrigerator door is opened and closed. The more times the refrigerator opens and closes, the greater the temperature difference between the inside and outside of the refrigerator, the more moisture inside the refrigerator, and the faster the refrigerator frosts. Therefore, we should try to minimize the number of times we open and close the refrigerator door, try to take out or put in the desired food at one time, and avoid repeatedly opening and closing the refrigerator door. At the same time, we should also pay attention to the tightness of the refrigerator door to ensure that the refrigerator door can be closed tightly to prevent the cold air from leaking out and moisture from entering.
Adjust the temperature setting of the refrigerator. The lower the temperature setting of the refrigerator, the greater the cooling capacity of the refrigerator and the faster the freezer will frost. Therefore, we should adjust the temperature setting of the refrigerator reasonably according to the season and the type of food, and avoid being too low or too high. Generally speaking, the temperature of the refrigerator is set in 7 settings, from 1 to 7, and the temperature is lowered in turn. We can refer to the following suggestions:
In winter, the temperature setting of the refrigerator can be adjusted to 3-4 gears, and the temperature of the refrigerator is about 5-8, which can not only ensure the freshness of the food, but also save electricity and reduce frosting.
In summer, the temperature setting of the refrigerator can be adjusted to 5-6 gears, and the temperature of the refrigerator is about 2-5, which can prevent the deterioration of food, improve the refrigeration effect, and increase frosting.
If a large amount of perishable food such as meat and seafood is stored in the refrigerator, the temperature setting of the refrigerator can be adjusted to 6-7 gears, and the temperature of the refrigerator is about -2-2, which can prolong the shelf life of food, prevent the breeding of bacteria, and speed up frosting.
Clean your refrigerator regularly. The worse the cleanliness of the refrigerator, the more dust inside the refrigerator and the faster the refrigerator will frost. Therefore, we should clean the refrigerator regularly, keep the refrigerator hygienic, and improve the efficiency of the refrigerator. We can clean the fridge by following these steps:
Disconnect the power of the refrigerator, remove all the food in the refrigerator, put it in a clean container, and wrap it in plastic wrap or thermal insulation bag to prevent the food from spoiling or emitting odors.
Wipe all parts of the inside of the refrigerator with warm water or neutral detergent, such as the refrigerator, freezer, drain pipe, water storage tray, etc., to remove dust, stains, odors, etc., and be careful not to use hot water or strong acid and alkali detergents to avoid damaging the surface or interior of the refrigerator.
Use a clean, dry cloth or paper towel to dry the inside of the refrigerator to ensure that the inside of the refrigerator is dry and prevent the moisture from condensing into frost.
Plug in the refrigerator again, adjust the temperature setting of the refrigerator, wait for the refrigerator to return to normal working condition, and then put the food back into the refrigerator, paying attention to sorting and placing to avoid cross-contamination or squeezing of the food.
Even if we take precautions, the fridge will inevitably get frost, so we need to de-ice the fridge regularly to keep it in good condition. Generally speaking, we can choose different de-icing methods according to the thickness of the frost in the refrigerator, as follows:
If the thickness of the frost in the refrigerator is less than 5 mm, we can use the natural de-icing method, that is, disconnect the power of the refrigerator, take out all the food in the refrigerator, then wait for the frost to melt naturally, wipe the moisture inside the refrigerator with a towel or paper towel, and then plug the power of the refrigerator back in to resume the work of the refrigerator.
If the thickness of the frost in the refrigerator is between 5-10 mm, we can use the method of hot water de-icing, that is, disconnect the power of the refrigerator, take out all the food in the refrigerator, and then soak some towels or rags in hot water, apply them to the refrigeration parts of the refrigerator to accelerate the melting of the frost, wipe the moisture inside the refrigerator with a towel or paper towel, and then replug the power of the refrigerator to resume the work of the refrigerator. Be careful not to use boiling or boiling water, so as not to cause thermal expansion and contraction of the refrigerator and damage the parts of the refrigerator.
If the thickness of the frost in the refrigerator is more than 10 mm, we can use the method of de-icing with a hair dryer, that is, disconnect the power supply of the refrigerator, take out all the food in the refrigerator, and then use the hair dryer to align the refrigeration parts of the refrigerator, with medium and low temperature and wind speed, from top to bottom, from left to right, evenly blow the air, so that the frost gradually melts, wipe the moisture inside the refrigerator with a towel or paper towel, and then replug the power of the refrigerator to resume the work of the refrigerator. Be careful not to use high temperature and wind speed, so as not to cause thermal expansion and contraction of the refrigerator and damage the parts of the refrigerator.
