What's the right temperature for the refrigerator?

The temperature control of the refrigerator should be adjusted according to the season. Is adjusting the temperature control actually adjusting the temperature difference coefficient? .

Generally speaking, the greater the temperature difference between inside and outside the box, the smaller the adjustment of temperature control coefficient. On the contrary, the smaller the temperature difference between inside and outside the box, the greater the adjustment of temperature control coefficient. ?

Generally speaking, the colder the weather (winter), the greater the adjustment (6.7). For example, when the ambient temperature is low in winter, it's best to turn on the winter temperature compensation switch at the same time, but don't forget to turn off this switch when the temperature gets warmer, otherwise it will consume a lot of electricity. The hotter the weather (summer), the smaller the adjustment (2.3). Generally, the middle tune (3.4) is better in spring and autumn. ?

Temperature compensation is essentially a low-power electric heater to heat the thermostat, so that the original non-conductive (open circuit state) thermostat contacts are conductive (closed circuit state).

The temperature changes all year round, especially in winter and summer. The outside temperature will directly affect the temperature inside the refrigerator. Once the refrigerator temperature is set incorrectly, the freezing effect will not be achieved if the temperature is too high; If the temperature is too low, the refrigerator will freeze and the food will freeze. Therefore, it is necessary to adjust the temperature of the refrigerator according to the change of temperature, and at the same time achieve the purpose of saving electricity and ensuring the freezing effect of food.

If we make a simple classification by temperature control, how can refrigerators be roughly divided into? Mechanical control and? There are two types of computer intelligent control.

1. Mechanical control type:

In the process of using mechanically controlled refrigerator, its working time and power consumption are greatly affected by the ambient temperature, which requires us to manually select different temperature gears in different seasons. There is a circular rotary switch in the refrigerator, which is marked with numbers from 0 to 7. 0 does not work, the larger the number, the stronger the refrigeration, and 7 is the highest intensity refrigeration.

When the ambient temperature is high in summer, it is recommended to set the thermostat to 2-3.

In summer, the ambient temperature is high, so it is difficult to reduce the temperature in the refrigerator by 1 degree. Even with insulation layer and door seal, the cooling capacity will be lost quickly, which will take a long time to start and a short time to stop. This phenomenon will lead to the long-term operation of refrigerator compressor at high temperature, which will aggravate the wear of piston and cylinder, and the insulation performance of motor coil enameled wire will also be reduced due to high temperature, and the power consumption will rise sharply, which is uneconomical and unreasonable. If the refrigerator is set to 2-3 gear (weak gear) at this time, the start-up time can be obviously shortened and the shutdown time can be prolonged, which not only saves electricity, but also reduces compressor wear and prolongs service life.

When the ambient temperature is low in winter, it is recommended to set the thermostat at the fourth gear or above.

The technical requirements of refrigeration temperature should be controlled between 0 ~ 10 degrees. In winter, the ambient temperature is relatively low, so the refrigeration can easily reach the set temperature. If the set temperature is too high, the start-up time of the refrigerator will be short and the refrigeration effect will not be achieved. The specific adjustment method is: when the ambient temperature is lower than 16 degrees, adjust it to the fifth gear; When it is lower than 10 degree, shift to 6th or 7th gear. When the ambient temperature is too low and needs to be adjusted to 0~5 degrees, food can be stored outside the refrigerator without wasting electricity ~

In spring and autumn, according to the ambient temperature, it can be appropriately adjusted to 3-4 grades.

2. Computer intelligent control type

At present, most refrigerators are controlled by computers. Taking Haier's computer-controlled refrigerator as an example, the intelligent sensor in the refrigerator senses the ambient temperature in real time, and automatically matches the reasonable rotation speed according to the changes of food reserves and internal and external temperatures, so as to achieve the effects of preservation, energy saving and silence. At the same time, the computer intelligent control type can also be manually adjusted according to its own needs, and the specific adjustment is the same as that of the mechanical type. The operation mode is still taking Haier refrigerator as an example. In the unlocked and artificial intelligence state, if the refrigeration adjustment key is pressed, the icon F will be displayed on the panel. After that, the temperature will drop by 1℃ until 3℃, and then return to 7℃. The temperature can be changed between 3℃ and 7℃, and it can be set successfully without any operation within 5 seconds after adjustment.
