First, the appropriate temperature of general food.
The recommended temperature of fresh food area is 2.7-4.4℃, and the temperature of freezer is-15℃. If there is a separate freezer to store food for a long time, its temperature should be kept at-17℃. For example, the refrigeration temperature of fresh meat and fish is about-1 degree, eggs and milk are about 3 degrees, and vegetables and fruits are about 5 degrees.
Second, the refrigerator temperature adjustment in summer
During the use of refrigerator (freezer), 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. When the ambient temperature is high in summer, it should be used in weak gear 2-3.
Reason: In summer, the ambient temperature is high. At this time, the temperature in the box is difficult to drop 1 degree, and the loss of cold energy through the insulation layer and door seal of the box will also be accelerated, so that the startup time is long and the shutdown time is short. This will cause the press to run at high temperature for a long time, which will aggravate the wear of the piston and cylinder, and the insulation performance of the enameled wire of the motor coil will also be reduced due to high temperature, and the power consumption will also rise sharply, which is uneconomical and unreasonable. If you change to the weak gear (2.3) at this time, you will find that the start-up time is obviously shortened and the shutdown time is prolonged, which not only saves electric energy, but also reduces compressor wear and prolongs service life. So when it is hot in summer, set the thermostat to a weak position.
Three, the winter refrigerator temperature adjustment
Generally, the gear should be above 4 in winter, and the ambient temperature is low in winter. If the refrigerator gear is too low, the compressor will stop running.
Reason: The product you bought only has a refrigerator thermostat to control the temperature of refrigeration and freezing. Because the refrigeration temperature is technically required to be controlled between 0 ~ 10 degrees, the refrigeration environment is relatively low in winter, and it is easy to reach the set temperature. If the set temperature is too high, it is easy to cause the refrigerator to start for a short time, which will lead to the failure of the refrigeration effect. In winter, if the ambient temperature is low, it is mainly to ensure the cooling effect. In general, the ambient temperature below 16 degrees can be adjusted to the fifth gear, and below 10 degrees can be adjusted to the sixth or seventh gear. Sometimes because the ambient temperature is too low, such as 0~5 degrees, the food can be stored outside the refrigerator after the downshift.
