What grade is the refrigerator temperature set to in spring?
Suggestion: 2-3 gears.
The temperature rises slowly in spring, and the temperature in most areas is close to 20 degrees. At this time, we need to change the shift switch of the refrigerator from 4-5 in winter to 2-3 to meet the needs of freezing food in spring.
What are the benefits of setting the refrigerator to 2-3 in spring?
1, which is more energy efficient.
The principle of refrigerator refrigeration is that the smaller the number, the lower the temperature, the better the refrigeration effect and the more power consumption. Therefore, the refrigerator should be controlled according to the needs of different seasons, so that the temperature can not only maintain the refrigeration temperature, but also reduce the power consumption of the refrigerator.
2. Meet the requirements of food refrigeration and freezing.
In spring, the required temperature of the freezer is-18 degrees, and the temperature of the freezer is 4-8 degrees. In spring, the temperature outside the refrigerator is about 20 degrees, and adjusting it to 2-3 degrees can meet the needs of food refrigeration and freezing.
3. Extend the life of the refrigerator
Control the compressor of the refrigerator according to the shift position. If the gear of the refrigerator itself is 2-3 in spring, it can meet the demand, but if you adjust it at will, it will increase the workload of the refrigerator, not only consume electricity, but also shorten the life of the condenser and compressor of the refrigerator.
There are many things in the refrigerator in spring, so it is more appropriate to adjust the third gear.
Above, we suggest that you adjust the refrigerator to the position of 2-3, but some housewives like to stuff the refrigerator full. In view of the fact that there is a lot of food in the refrigerator, I suggest you adjust to the third gear, which will have a better effect on food insurance.
How many levels of refrigerator temperature adjustment in different seasons?
The gear of thermostat should be adjusted according to the seasonal temperature change. It was suggested that:
1, shift between 4 and 5 in winter;
2. Adjust to 2-3 files in spring and autumn;
3. Adjust in 1-2 in summer.
In general, the ambient temperature below 16 degrees can be adjusted to the fifth gear, and below 10 degrees can be adjusted to the sixth or seventh gear. Sometimes because the ambient temperature is too low, such as 0-5 degrees, everything freezes after downshifting. At this time, food can be stored outside the refrigerator to save electricity.
How to use the refrigerator to save electricity?
1, don't put the food too slowly.
There should be a gap of about 10mm between the food stored in the refrigerator and the box wall, and between food and food. The middle layer of the refrigerator should not be too full, which is conducive to the circulation of cold air, electricity saving and food preservation.
2. Make frozen food at night.
The low temperature at night is beneficial to the heat dissipation of the condenser. Therefore, if you want to freeze ice or make cold drinks, it is more energy-saving to do it at night than during the day.
Put the refrigerator in a cool and dark place.
Try to keep the refrigerator in a cool place to avoid direct sunlight. Put it in a cool and ventilated place, away from the wall 10cm, which can not only dissipate heat, but also reduce the temperature difference with the outside world and save electricity. Because every time the temperature around the refrigerator rises by 5 degrees, its internal power consumption will increase by 25%.
4. Reduce the frequency of opening and closing the refrigerator door.
Minimize and shorten the opening time and times. Think about what to take before opening the refrigerator, and what else needs to be put in, all at once. Because every time the refrigerator opens the door, the temperature in the refrigerator will recover, the compressor will work and consume more electricity.
Step 5 defrost regularly
It is suggested that the refrigerator should be defrosted once every 1 month, because it is easy to frost when the temperature of the refrigerator is too low, and it is easy to reduce the performance of the refrigerator and consume a lot of electricity when the frost is too thick.
6. Power failure and power saving tips
It takes a long time to restart the refrigerator after the power failure in hot summer. You can use small plastic bags to freeze some water into ice cubes and keep them in the freezer all the time, so that the temperature in the refrigerator will not rise too fast when there is power failure.
Common sense of food storage in refrigerator
1, the food in the refrigerator also has a shelf life.
The refrigerator mainly slows down the reproduction of bacteria through low temperature, but it can't kill bacteria, so the food in the refrigerator also has a shelf life. Moreover, although most bacteria grow slowly below 10℃, some bacteria can survive or even reproduce at low temperature, so it is necessary to store food in a refrigerator with appropriate temperature, and it is not appropriate to store food with too high temperature or cross-store raw and cooked food.
Pay attention to the temperature difference when eating food in the refrigerator.
If the food just taken out of the freezer is eaten quickly, it will stimulate the oral mucosa, reflexively cause vasospasm in the head, and produce a series of symptoms such as headache, dizziness and nausea. After the gastrointestinal tract is stimulated by intense low temperature, the blood vessels will suddenly contract and become thinner, the blood flow will also decrease accordingly, the digestive juice of the gastrointestinal tract will stop secreting, and symptoms such as paroxysmal colic and upper abdominal vomiting will appear. Many children with "refrigerator gastritis" will have symptoms of nausea and vomiting after eating frozen food for half an hour.
3. The dishes must be heated immediately after the cold meal.
The storage room temperature of refrigerator is generally 4 ~ 65438 00℃. When food is taken out of the refrigerator, it should be heated immediately. If it is left in the air for a period of time, the process of gradual warming will make bacteria multiply, because 4~ 10℃ is just the suitable temperature for bacterial reproduction, and gradual warming is equivalent to creating a good environment for bacterial reproduction. Once people eat leftovers that are not completely heated, they will not have diarrhea.
4. Vegetables should not be stored for a long time.
Fruits and vegetables should not be stored in the refrigerator for a long time, especially leafy vegetables with high nitrate content. Although nitrate itself is not toxic, after vegetables are stored for a period of time, nitrate is reduced to nitrite due to the action of enzymes and bacteria, and nitrite is a toxic substance that causes cancer.
5. Whether fruits are put into the refrigerator must be classified.
Most fruits are white and cold, so they are not suitable for cold storage in the refrigerator. The skin is sunken and some dark brown spots appear, indicating that the fruit has been frostbitten. Frostbite fruits are not only destroyed in nutrients, but also easy to deteriorate.
Some temperate fruits, such as grapes, apples and pears, are kept fresh in the refrigerator.
Tropical fruits, such as bananas and mangoes, will turn black when stored at a temperature of more than ten degrees; When pineapple is stored at 6~ 10℃, not only the peel will change color, but also the pulp will be soaked in water. When litchi, longan and rambutan are stored at 1~2℃, the color of the exocarp will become darker, and some spots similar to burns will appear on the endocarp, so the fruits can no longer be eaten.
6, food in the refrigerator for a long time, serious nutrient loss.
Food must be fresh and clean before storage, and it should not be stored in the refrigerator for too long. All kinds of refrigerators can't prevent some nutrients, such as amino acids, minerals, B vitamins, vitamin C and other nutrients from decomposing or losing.
Recommendation: 12 A great trick to use the refrigerator skillfully in life.
Wonderful use 1: Restore moist food.
In daily life, we often find that food that has not been eaten after unpacking is easy to get wet, such as melon seeds and biscuits. If it is left for a long time, it will become wet and soft, and finally we have to throw it away. In fact, just put wet melon seeds or biscuits in the freezer and freeze them 12 hours before taking them out, and they will be brittle again!
Magic 2: Let the beans boil quickly.
Many people like to drink miscellaneous grains porridge, but beans such as red beans and soybeans are difficult to cook thoroughly without soaking. If boiled in water, let it cool and put it in the freezer for about 2 hours. After the water surface freezes slightly, take it out and heat it again. It only takes 20 minutes for the beans to become soft, rotten and delicious. This is because of the principle of thermal expansion and cold contraction. In this way, the beans can be cooked and bloom quickly.
Clever application 3: chestnut hulling quickly
Every season when chestnuts are ripe, charming chestnut fragrance floats in the streets and alleys. If you love chestnuts, you must know that chestnuts are not easy to peel after being cooked, but as long as they are cooled and frozen in the refrigerator for 2 hours, the shell and flesh of chestnuts will quickly "break up", and it is no longer difficult to peel the whole chestnut meat.
Wonderful use 4: make fried rice more delicious
The food cooked in restaurants is always delicious, but it is not cooked at home. Then why? Teach you a little secret! After cooling the cooked rice, put it directly into the freezer, freeze it for 2 hours, and then take it out and cook it. Fried rice will be very clear and chewy.
Magic five: remove the spicy taste of food
When cutting onions, onions, garlic and other spicy vegetables, their spicy taste usually stimulates us to burst into tears. If we put onions in the refrigerator for an hour or two in advance, and then take them out and cut them after the spicy substances are stable, our eyes will not be smoked at all.
Magic six: dilute the bitter taste of bitter gourd
Although bitter gourd has the effect of clearing heat and removing fire, it is extremely bitter and difficult to swallow. If you put bitter gourd in the fresh-keeping layer of the refrigerator for a period of time and then take it out to eat, its bitterness will become much lighter.
Clever use of seven: thawing meat to retain nutrition
When thawing meat, we often use microwave heating or hot water soaking. However, both methods will lead to the loss of nitrogen, vitamins and minerals in meat and increase the risk of microbial growth.
In fact, the most ideal way is to put the meat to be thawed in the lower layer of the refrigerator the night before. This not only thaws evenly, but also reduces the loss of nutrients, reduces the risk of food poisoning in summer, and tastes good.
Skillful use of eight: restore the hardness of soap
Soap has been used in the bathroom for a long time. Because of frequent contact with water, it is easy to become mushy and soft, which is not only ugly, but also particularly difficult to use. At this point, if you put the soap in the refrigerator for half an hour, the soap will immediately return to its original "solid" appearance.
Clever use of nine: candles can burn without dripping wax.
Before using the candle, put it in the refrigerator for 4 hours. Frozen candles are not easy to drip wax when lit, but will burn more slowly and permanently, avoiding the embarrassment of candles dripping on birthday cakes!
Skillful use of ten: extend the life of stockings
Don't unpack the newly bought stockings, just put them in the freezer 1~2 days, and then take them out to dry for about half a day before wearing them. This will increase the toughness of stockings, making them less likely to hook and tear.
Magic eleven: remove gum stains
Once chewing gum sticks to an object, it is difficult to remove it. At this time, we can put the things with chewing gum in the refrigerator and freeze them 1 hour or so before taking them out. Chewing gum will become brittle and hard, and it will be easily removed with a light pick.
Clever use 12: Make wet books new.
Books collected at home will grow moth after a long time. We can wrap the books in plastic film bags and put them in the refrigerator 12 hours, and the moths will freeze to death.
In addition, if the book is accidentally spilled with water, it will become uneven after drying. The correct way is to smooth the wet book, immediately put it in the freezer of the refrigerator, freeze it for one night, take it out the next day, shake off the ice residue, and the book will miraculously recover.
