What is the optimum temperature for the refrigerator? What do the refrigerator temperature adjustment numbers 1-7 mean? The temperature control knobs generally have 0, 1, 2, 3, 4, 5, 6, 7. The larger the number, the lower the temperature in the freezer. The gear of the refrigerator is generally adjusted according to the local climatic conditions. Generally, it is adjusted to 1~2 gears in summer, 3~4 gears in spring and autumn, and 5~6 gears in winter, and the low temperature compensation switch is turned on. In the spring and autumn, the low temperature compensation switch can be turned off.
Refrigerator temperature adjustment
The meaning of the refrigerator temperature adjustment number
Unless the temperature of your home is like spring all year round, then your refrigerator Once the temperature is adjusted, there is no need to change it. Otherwise, due to the large temperature difference between summer and winter, in order to save electricity and ensure the quality of food freezing, it is necessary to adjust the temperature control knob of the refrigerator in summer and winter.
Adjustment method The temperature control knob generally has 0, 1, 2, 3, 4, 5, 6, 7 gears. The higher the number, the lower the temperature in the freezer. Generally, we put it on the 3rd gear in spring and autumn, depending on your requirements, whether the freezer can reach below minus 18 degrees. In order to achieve the purpose of food preservation and power saving, we can switch to gear 1 or 2 in summer, and gear 4 or 5 in winter.
Refrigerator temperature adjustment
Summer temperature adjustment During the use of refrigerators (freezers), their working time and power consumption are greatly affected by the ambient temperature, so we need to adjust the temperature in different seasons. To choose a different gear to use. When the ambient temperature is high in summer, it should be used in the weak gear 2-3.
Reason: In summer, the ambient temperature is high, and it is very difficult for the temperature in the box to drop by 1 degree. The time is long and the downtime is short. This will cause the press to run at high temperature for a long time, aggravate the wear of the piston and the cylinder, the insulation performance of the motor coil enameled wire will also be reduced due to the high temperature, and the power consumption will also rise sharply, which is uneconomical and unreasonable. If you switch to the weak gear (2.3) at this time, you will find that the startup time is significantly shorter and the downtime is longer, which not only saves electricity, but also reduces the wear of the compressor and prolongs the service life. Therefore, when the temperature is high in summer, the thermostat is adjusted to the weak file.
Winter temperature adjustment In winter, the general gear should be set to 4 or above. The reason is: the product you purchased only has a refrigerating room controller to control the temperature of refrigeration and freezing, due to the technical requirements of refrigerating temperature control It is between 0 and 10 degrees, and generally in winter, the refrigeration environment is relatively low, and refrigeration can easily reach the set temperature. If the set temperature is too high, it is easy to cause the refrigerator to be turned on for a short time, resulting in the freezing and cooling effect. The ambient temperature is low, mainly to ensure the cooling effect of freezing. Under normal circumstances, if the ambient temperature is lower than 16 degrees, adjust to the 5th gear, and if it is lower than 10 degrees, it can be adjusted to the 6th or 7th gear. Sometimes because the ambient temperature is too low, such as 0~5 degrees, the gear is lowered and the frozen things are refrigerated. At this time, the food can be stored outside the refrigerator.
The switch of the low temperature compensation switch The product system you purchased belongs to a single system refrigerator, and there is only one refrigerating room temperature controller to control the temperature of refrigeration and freezing. Due to the technical requirements of refrigeration temperature, it is controlled between 0 and 10 degrees. Therefore, when the ambient temperature is close to the temperature of the storage room, the refrigerating machine will reach the temperature in a short time or even if it is not turned on. In order to avoid the shutdown or short startup time in winter, the production department has specially designed a set of low temperature compensation or switching device for single-system refrigerators. This device is used to ensure that the ambient temperature can work normally in winter. Therefore, it needs to be turned on when the ambient temperature is lower than 16 degrees. Low temperature compensation or switch (see the manual for details). In addition, pay attention to the ambient temperature not lower than 10 degrees, and adjust the thermostat to the strong position.
What is the optimum temperature for the refrigerator
The temperature control of the refrigerator should be adjusted according to the season. Adjusting the temperature control is actually adjusting the temperature difference coefficient. Generally speaking: the larger the temperature difference between the inside and outside the box, the smaller the adjustment of the temperature control coefficient, on the contrary, the smaller the temperature difference between the inside and outside the box, the greater the adjustment of the temperature control coefficient. The most important thing is that the gear is adjusted according to the season and the condition of the refrigerator! “The smaller the weather is to adjust the heat, the greater the adjustment is to the colder the weather.” Master this principle.
The temperature of the freezer should be lower than minus 18 degrees, and the temperature of the refrigerator should be between 1-10 degrees. Generally, the thermostat of the refrigerator is set in the refrigerator, and it can be adjusted in the summer. Low gear, between 1-3 gears is fine. It can be adjusted to the middle gear in spring and autumn, and it can be adjusted higher in winter. At the same time, turn on the winter temperature compensation switch, but don’t forget to turn off this switch when the temperature gets warmer, otherwise it will cost a lot of electricity. When the room temperature is below 10°C, the thermostat should be set to the “6” position. 7 is the highest level. After adjustment, it is the quick-freezing state of the refrigerator. It needs to be adjusted back after use, otherwise the refrigerator will not stop working. If you want to save trouble, you can adjust the thermostat to the middle gear. Remember: In the case of not affecting the freshness of the food in the refrigerator, it is the most power-efficient to adjust the thermostat to the low gear (first gear).
During the season change, the gears of the refrigerator are generally adjusted according to the local climatic conditions. Generally, the gears of the refrigerator are adjusted to 1~2 gears in summer, 3~4 gears in spring and autumn, and 5~6 gears in winter and low temperature compensation is turned on. switch. In the spring and autumn, the low temperature compensation switch can be turned off.
What’s the matter with the poor refrigeration of the refrigerator
1. Because of the poor heat dissipation in summer, the location of the user’s refrigerator is not conducive to heat dissipation.
2. Too much food put in at one time exceeds the freezing capacity.
3. The temperature setting in winter is too low, resulting in a short boot time of the refrigerator.
4. The low temperature compensation switch is not turned on.
5. The volume of frozen food is relatively large and it is easy to cause poor refrigeration effect.
The best temperature for storing different foods in the refrigerator
1. The best refrigeration temperature for fresh fish is minus 3 degrees.
2. Meat should be refrigerated at 2 degrees to 5 degrees. Can be stored for one week.
3. The best temperature for storing wine is 5 degrees to 20 degrees.
4. Barrel beer and bottled beer should be stored at 0 to 5 degrees, while bottled beer should be stored at 10 to 25 degrees.
5. The best temperature for refrigerating fresh milk is 2 to 4 degrees.
6. The tea leaves are stored at a temperature of minus 20 degrees to 10 degrees, which can prevent the quality from deteriorating for a long time and keep the vitamins from being damaged.
7. The best temperature for miscellaneous grains: 8 degrees to 15 degrees, which can prevent the food from worms.
8. The best temperature for frozen fish: it is below minus 3 degrees, at this temperature the fish is not easy to deteriorate, and its freshness can be preserved.
9. The best temperature for eggs: below 15 degrees, eggs are not easy to spoil. >>
Common fault solutions for household refrigerators
Thickness of frost in the refrigerator compartment
1. Is the door seal tight: if the door is not tightly sealed, the entry of outside air may cause thick frost .
2. Whether food with excessive moisture is placed: If there is food with excessive moisture to be placed, it is best to pack it.
3. Whether the door is opened too frequently: not recommended Open the refrigerator frequently.
4. Whether there is no defrosting for a long time: It is recommended to defrost the refrigerator regularly.
5. Whether the ambient humidity is too high in summer: the frost in the refrigerator is generally It is automatically defrosted, but when the ambient humidity is high in summer, sometimes the frost on the back of the refrigerator cannot be completely melted away, forming a certain amount of ice, so it must be removed in time.
High power consumption of the refrigerator
The rated power consumption marked in the refrigerator manual is according to the national standard. Controlled at -18°C, the value measured by running stably for 24 hours without opening the door. When measuring according to the standard, there are other conditions, such as humidity, wind speed, etc., but in actual use, due to changes in the environmental conditions of the refrigerator , as well as the number of foods placed in use, the number of times the door is opened, etc. will affect the actual power consumption. Sometimes even when the temperature is lower than 25 ℃, due to various conditions, the actual power consumption will sometimes be higher than the rated power consumption, and It is not that the lower the temperature, the lower the actual power consumption, because sometimes the actual power may change after the temperature is lowered, affecting the power consumption.

How to choose a refrigerator
Don’t blindly pursue high prices
There are many factors that affect the price of refrigerators, not only This item of technology. Well-known brands, advertising costs, internal management costs, etc. are all important factors that affect the price of the refrigerator. And now, the technology of electronic technology products is more and more mature, and the production process is also more and more advanced. Costs are constantly decreasing, and the manufacturing costs of refrigerators from major manufacturers are also similar. When you buy a refrigerator, you must keep your eyes open, and don’t pay extra because of the high cost of brand promotion.
Focus on the practicality of the refrigerator
One of the important factors to measure the performance of the refrigerator is the freezing power. The refrigerators we buy for our homes are generally used to store vegetables and fruits and other foods for freshness. And does not need a strong freezing function. Unlike commercial refrigerators that are primarily used for freezing. Therefore, when choosing a refrigerator, choose a refrigerator that is suitable for household needs, and do not pursue the freezing capacity too much, increasing unnecessary power consumption and other expenses.
Do not blindly pursue aesthetics
A refrigerator that is too small and exquisite may have a thin external insulation layer, and its service life may be shorter than normal, and its quality may not be as good as other refrigerators. In addition, the capacity of the refrigerator should also be an important consideration when you buy a refrigerator. A refrigerator that is too small has a small capacity, which may be difficult to meet the daily necessary storage capacity of a family.
To choose the refrigerator with the best power consumption
The power consumption of a refrigerator is related to its size, volume, and cooling capacity. If a refrigerator with a larger volume consumes very little power, the cooling effect of the refrigerator may not be so good. Of course, the use of some new technologies such as inverter refrigerators can indeed save power consumption for refrigerators. It’s just that the price may also increase at this time.
Carefully inspect the outside of the refrigerator for damage
Choose a refrigerator with a square appearance and a good compressor and other accessories. This needs to be checked carefully when buying a refrigerator. Also check whether the door seal of the refrigerator is in good condition. If the door seal is not tight enough, it may directly affect the refrigeration effect and power consumption of the refrigerator.
Inspect the interior of the refrigerator for completeness
In particular, check the condition of the lights inside the refrigerator.
Check the performance of the compressor of the refrigerator
See if the compressor starts automatically immediately after the power is turned on.
