The temperature distribution in the freezer is uneven. The temperature of the freezer presents a temperature gradient from top to bottom, with the lowest temperature in the upper layer, about 3℃, and the highest temperature in the lower fruit and vegetable box, about 6~ 10℃. According to the national standard, the temperature of the freezer should be between 3~ 10℃. A simple way to measure the temperature of the refrigerator is to put the thermometer in a cup filled with water. It is located on the middle floor near the back wall. Measure for at least 2 hours, then measure the temperature of the upper and lower layers, and finally take the average. At the "4" level, the temperature of the general refrigerator is around 7℃. The reasons for the high temperature of the refrigerator are: a) the ambient temperature is high, and the heat dissipation of the refrigerator condenser is not good; B) The refrigerator is not placed properly, and there is not enough space around it to dissipate heat; C) The refrigerator door is not tightly sealed; D) the ice making system is blocked.
What's the temperature in the refrigerator?
What's the average temperature in the freezer? The refrigeration temperature of the refrigerator can be adjusted as follows.
The temperature of the fresh-keeping room of the refrigerator can be set at 4-5 degrees, which is beneficial to the fresh-keeping of food and can be kept fresh for 3-5 days.
If the refrigerator has a cold room (variable temperature room), the temperature can be set at 0 degree or 1 degree, and the food can be refrigerated without freezing.
The quick-freezing room of the refrigerator can be set at minus 18℃, which is faster in quick-freezing and is beneficial to accelerate the quick-freezing of food.
The temperature setting of the above refrigerator can be constant all the year round.
This is the temperature of my refrigerator. Has it changed all the year round? It has been used for several years now, and it is very good.
In general, how many degrees below zero is the temperature in the freezer?
The temperature of the freezing chamber of the refrigerator changes with the adjustment of the thermostat. According to national standards, it is generally below zero 18℃ The temperature of the freezer is MINUS 7 degrees. The temperature of the refrigerator is 4℃. The freezing room should be about-18 degrees, and the refrigerating room should be between 0- 10 degrees.
But generally speaking, the specific temperature depends on the food in your own freezer. When the frost in the freezer is thick (about 1cm), it is suggested to defrost in time, which can improve the refrigeration effect in the freezer.
In addition, according to the type of refrigerator condenser, if it is rear-hung, the condenser should be cleaned in summer, because it can improve the refrigeration efficiency of refrigerator. If it is flat-backed, it is suggested to leave a certain space on both sides of the refrigerator, which is beneficial to heat dissipation and can improve work efficiency.
What is the freezing temperature of the freezer?
Generally, the temperature of the refrigerator is 0℃- 12℃.
Refrigerator temperature:
1. In fact, the temperature distribution in the cold storage room is uneven. The temperature of the cold storage room presents a temperature gradient from top to bottom, with the lowest in the upper floor, about 3℃, and the highest in the lower fruit and vegetable box, about 6~ 10℃. According to the national standard, the temperature of the refrigerator should be between 3~ 10℃.
2. A simple way to measure the temperature of the refrigerator: put the thermometer in a cup filled with water, and then put the cup in the refrigerator, which is located on the middle floor near the back wall. Measure for at least 2 hours, then measure the upper and lower temperature, and finally take the average. Under normal circumstances, when in the "4" position, the temperature of the general refrigerator is about 7℃.
Generally speaking, it is a principle to adjust between 3 and 4 in summer and between 1 ~ 2 in winter. The temperature of the refrigerating room shall be kept at 5~ 10 degrees Celsius. Fresh fish and meat should be packed in plastic bags and then stored in the refrigerator. Vegetables and fruits should be dried on the outer surface, put in the bottom of the refrigerator and stored at zero temperature.
Is the temperature of refrigerator, freezer and freezer appropriate?
1, the refrigerator is a tool to provide food preservation, and different foods need different preservation temperatures, so the temperature of the refrigerator should be set according to the types of stored foods, such as green leafy vegetables 12, tropical fruits 10, cooked food 8, beer and beverage 4, fresh meat-18, fish and shrimp 0, etc. In principle, it has nothing to do with the season. 2. The freezer temperature range is -4~-24 degrees (three-star-18 degrees, four-star -24 degrees), and the freezer temperature range is 5~ 15 degrees. When the mechanical thermostat is adjusted, the freezer temperature and freezer temperature change simultaneously. 3. When the ambient temperature is higher than 30 degrees in summer, it is necessary.
What's the right temperature for the freezer?
The temperature should be 3~4 in summer and 1~2 in winter, or 2. It is more appropriate to keep the temperature of the refrigerator at 5~ 10 degrees Celsius.
In general, the refrigerator thermostat has 0, 1, 2, 3, 4, 5, 6 and 7 levels. The higher the gear, the lower the temperature of the freezer. In fact, the temperature distribution in the cold storage room is uneven. The temperature of the cold storage room presents a temperature gradient from top to bottom, with the lowest in the upper floor, about 3℃, and the highest in the lower fruit and vegetable box, about 6~ 10℃. According to the national standard, the temperature of the refrigerator should be between 3~ 10℃.

How to use:
1. Temperature compensation switch
The use method of refrigerator temperature compensation switch is a refrigerator with wide climate zone designed according to the characteristics of large temperature difference between the north and the south of China. When the ambient temperature is low (below 10℃), please turn on the temperature compensation switch for normal use.
When the ambient temperature is low, if the temperature compensation switch is not turned on, the working times of the compressor will be obviously reduced or will not work, and the start-up time will be short and the shutdown time will be long, resulting in the high temperature of the freezing chamber and the frozen food cannot be completely frozen. Turning on the temperature compensation switch will not affect the service life of the refrigerator.
After winter, when the ambient temperature rises and is higher than 15℃, please turn off the temperature compensation switch to avoid frequent start-up of the compressor and save electricity.
2. Temperature controller
How to use the refrigerator thermostat In the process of using the refrigerator, its working time and power consumption are greatly affected by the ambient temperature, so we need to choose different gears to use in different seasons. Refrigerator thermostat should be turned on at low level in summer and at high level in winter.
When the ambient temperature is high in summer, it should be used in weak gear 2 and 3, and when the ambient temperature is low in winter, it should be used in strong gear 4 and 5. When the ambient temperature is low in winter, if the thermostat is still set in the weak position, the temperature difference between inside and outside will be small, the compressor will not be easy to start, and the refrigerator with single refrigeration system may be frozen in the freezing room.

What is the temperature of the refrigerator from refrigeration to freezing?
The freezer is at 0- 10 degrees.
The freezer is between 0 and -5 degrees.
The freezing room should be between-16 degrees and -24 degrees.
Refrigerator is a kind of refrigeration equipment to keep a constant low temperature, and it is also a civilian product to keep food or other items at a constant low temperature. There are compressors, ice makers, cabinets or boxes for refrigeration, and there are storage boxes with refrigeration devices in the boxes.
The volume of domestic refrigerators is usually 20~500 liters. 19 10 the world's first compressed refrigeration household refrigerator came out in the United States. 1925 Lido Company of Sweden has developed a household absorption refrigerator. 1927 the general electric company of the United States has developed a fully enclosed refrigerator. 1930, air-cooled continuous diffusion absorption refrigerators with different heating methods were put on the market. 193 1 year, a new refrigerant freon 12 was successfully developed. Domestic thermoelectric refrigerators began to be produced in the second half of 1950s, and refrigerators began to be produced in China in 1950s.

According to the classification of boxes, the working principle is as follows:
1) compression refrigerator: this refrigerator is provided with mechanical energy by a motor and works on the refrigeration system through a compressor. The principle of refrigeration system is that the refrigerant with low boiling point absorbs heat when it evaporates. Its advantages are long service life and convenient use. 9 1~95% refrigerators in the world belong to this category. Commonly used refrigerators use a refrigerant called R600 refrigerator A as a hot "porter" to "carry" the heat in the refrigerator to the outside of the refrigerator.
2) absorption refrigerator: this refrigerator can use heat sources (such as gas, kerosene, electricity, etc.). ) as a driving force. Ammonia-water-hydrogen mixed solution realizes refrigeration in the process of continuous absorption-diffusion. Its disadvantages are low efficiency and slow cooling, which has been gradually eliminated.
3) Semiconductor refrigerator: It is a refrigerator that produces Peltier effect at the junction by applying direct current to PN semiconductor.
4) Chemical refrigerator: It is a refrigerator that uses some chemicals to absorb heat strongly when they are dissolved in water to obtain refrigeration effect.
5) Electromagnetic vibration refrigerator: It is a refrigerator with electromagnetic vibration machine as the main power to drive the compressor. Its principle and structure are basically the same as that of the compression refrigerator.
6) Solar refrigerator: It is a refrigerator that uses solar energy as refrigeration energy.
7) adiabatic demagnetization refrigeration refrigerator.
8) Radiant refrigeration refrigerator.
9) Solid refrigeration refrigerator.
