How to adjust the temperature of refrigerator and how to maximize refrigeration?

There are two kinds of refrigerators, one is gear and the other is temperature control. The refrigerator temperature is between -2 and -8 degrees, and the freezer temperature is about-18 to -24 degrees! The refrigerator generally has 1-7 adjustment buttons, which can be adjusted to 2-3 in summer and 6-7 in winter, mainly because the external temperature will affect the performance of the refrigerator, so the different gears make the inside and outside of the refrigerator have a good integration. Generally speaking, the temperature of the refrigerator is kept at about 5-8 degrees. Generally, the temperature control knob of refrigerator has five levels: 0, 1, 2, 3, 4, 5, or 0, 1, 2, 3, 4, 5, 6, 7. Here, gear 0 is gear, and gears 5, 6 and 7 are forced cold gears. When the thermostat is set at the forced cold position, the compressor will work continuously and the refrigerator will run almost all the time because of the low control temperature. The higher the thermostat value, the lower the temperature of the freezer. Generally adjust the 5th gear, 2nd-3rd gear. For gear 7, after gear 3-4, control the freezing-18 degrees, and keep the cooling at 5 degrees. When the temperature is high in summer, the temperature inside the refrigerator will be affected. Correctly adjusting the temperature range can save electricity. The temperature range of the refrigerator is zero to seven degrees, and it can be adjusted to two or three degrees in summer, which saves electricity and keeps food fresh. The more temperature stalls on the refrigerator, the lower the temperature. In summer, if the temperature of the refrigerator is adjusted to the third level or above, in order to meet the low temperature of the refrigerator, the refrigeration temperature of the compressor is actually sufficient, which increases the workload, not only consumes electricity but also damages the service life of the refrigerator.
