It is more appropriate to adjust the temperature in the freezer at 3~4 in summer and 1~2 or 2 in winter, and keep the temperature in the freezer at 5~1 degrees Celsius.

under normal circumstances, the refrigerator thermostat * * * has , 1, 2, 3, 4, 5, 6, 7 gears, and the higher the gear number, the lower the temperature of the freezer. In fact, the temperature distribution in the cold storage room is uneven. The temperature in the cold storage room presents a temperature gradient from top to bottom, with the lowest temperature in the upper layer, about 3℃, and the highest temperature in the fruit and vegetable box at the lower layer, about 6 ~ 1℃. According to the national standard, the temperature of the refrigerator should be between 3 ~ 1℃.

Extended information

Usage:

1. Temperature compensation switch

The usage of refrigerator temperature compensation switch is a wide climate refrigerator designed according to the characteristics of large temperature difference between the north and the south of China. In the case of low ambient temperature (below 1℃), 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 startup 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.

when winter passes and the ambient temperature rises and is higher than 15℃, please turn off the temperature compensation switch, so as to avoid frequent start-up of the compressor and save electricity.

2. thermostat

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. The refrigerator thermostat should be turned on at low gear in summer and high gear in winter.

when the ambient temperature is high in summer, it should be used in the weak gear 2 and 3, and when the ambient temperature is low in winter, it should be used in the strong gear 4 and 5. When the ambient temperature is low in winter, if the thermostat is still set to the weak gear, the temperature difference between inside and outside will be small, so the compressor will not be easy to start, and the refrigerator with single refrigeration system may also freeze.
