The refrigeration principle of commercial refrigerators is that the compressor produces a series of physical changes by compressing the refrigerant to achieve the refrigeration effect, but it is also very susceptible to the external environment, especially in seasons with large temperature changes, such as summer and winter. At this time, we need to adjust the temperature to make it work normally.
Methods for adjusting the temperature of refrigerators
Winter temperature adjustment
The temperature of the refrigerated area is generally 2~8℃. In winter, the indoor temperature is close to this temperature, and the compressor rarely starts. Although the temperature of the refrigerated area can meet the requirements, the temperature of the frozen area cannot reach minus 18℃, and the food is easy to deteriorate. In severe cases, the food thaws and melts, so the temperature of the refrigerator should also be lowered in winter, which can save more electricity and stabilize the refrigeration.
① Direct cooling refrigerator: Generally, it is appropriate to adjust to 4 gears or above. For example, when the ambient temperature is lower than 16 degrees, the cabinet temperature should be adjusted to 5 gears; when the ambient temperature is lower than 10 degrees, it can be adjusted to 6-7 gears, which can save more electricity and facilitate refrigeration.
② Air-cooled freezer: LVNi air-cooled freezer uses electronic temperature control board to control temperature, precise temperature control, and appropriately adjusts the temperature according to the ambient temperature to avoid the compressor not starting because the indoor temperature is close to the temperature inside the cabinet.
Summer temperature adjustment
When the ambient temperature is very high in summer, it will be relatively difficult to reduce the internal temperature of the commercial freezer, and the startup time will become longer, and the compressor is also prone to overload. At this time, it is also necessary to adjust the temperature of the freezer. The compressor will not be damaged so easily if it does not need to operate frequently, which can also save energy and increase its life.
Refrigeration effect
Adjust the temperature according to the season. There is still a certain deviation between the internal and external temperatures of different freezers. This not only requires us to adjust the temperature and wait for the freezer to run for a period of time before checking the refrigeration effect of the cabinet food, but also needs to choose a good quality freezer.
