What does Haier refrigerator 1 to 7 mean? How should the season be adjusted?

Temperature adjustment method of refrigerator 1 7:

1, the refrigerator is marked with numbers from 0 to 7, where 0 does not work, the larger the number, the stronger the refrigeration, and 7 is the highest intensity refrigeration. Just turn the button to adjust the temperature, generally 2~3 in summer, 3~4 in spring and autumn, and 5~7 in winter.

2. In summer, due to the high temperature of the external environment, it is difficult to lower the refrigerator at one time, so the start-up time will be longer and the shutdown time will be shorter. At the same time, the compressor will work for a long time at high temperature, which will damage the piston and cylinder and increase the power consumption, which is neither economical nor reasonable.

If you play the second or third gear, the startup time and shutdown time will be balanced, saving energy, reducing wear and increasing the service life of the refrigerator.

3. When the temperature outside the refrigerator is low in winter, it is more appropriate to adjust the gear to above 4 degrees. However, if the ambient temperature is lower than 10 degree, it will be adjusted to the fifth gear, and if the ambient temperature is lower than 10 degree, it will be adjusted to the sixth gear or the seventh gear, so as to ensure the normal operation of the refrigerator compressor and thus make the refrigerator operate normally.

4. When the ambient temperature is low (below 10℃), 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, which will lead to the high temperature of the freezing room and the frozen food cannot be completely frozen, so the temperature compensation switch must be turned on before it can be used.

Extended data:

The purpose and precautions of adjusting the refrigerator gear;

First, the purpose of adjusting the refrigerator gear:

The working principle of refrigerator is heat transfer between ambient temperature and indoor temperature. The greater the temperature difference, the longer the refrigerator runs and the more power it consumes. Then the purpose of adjusting this gear is to reduce the working pressure of the refrigerator, reduce the operating burden of the compressor and save some electricity. The higher the gear, the lower the temperature in the refrigerator.

Second, adjust the gear points for attention:

1, and the temperature control is adjustable in 2-3 gears in spring and autumn; When the room temperature is lower than 10℃, the thermostat should be set to "6". Some refrigerators are zero, which means that the refrigeration can be turned off. You can also follow the instructions on the refrigerator.

2. The outdoor temperature is high in summer, and the temperature can be adjusted to 3-4 grades, and the temperature is generally around 4℃-6℃; This not only ensures the downtime of the refrigerator, but also ensures the refrigeration effect of the refrigerator. On the contrary, it will cause the refrigerator to start or stop for a long time;

3. In winter, due to the low ambient temperature and rapid heat dissipation, the temperature control can be adjusted to 5-7, and the temperature is generally around 2℃-4℃; When the ambient temperature of the refrigerator without automatic switch for winter temperature is lower than 16℃, it is necessary to use strong gear or turn on the low temperature compensation switch to ensure the operation rate and freezing effect of the refrigerator. Otherwise, the refrigerator will not be turned on or thawed.

4. This is only the use of mechanical temperature control refrigerator gear control, and now there are also computer temperature control refrigerators. This kind of refrigerator is mainly a refrigerator whose temperature is controlled by computer programs. The biggest feature of computer-controlled refrigerator is accurate temperature control without manual temperature compensation switch. In other words, there is no need to manually adjust the temperature.
