The temperature represented by switch 1 ~ 7 in tcl old refrigerator is as follows: 1 gear temperature is about 9℃~ 10℃, gear 2 temperature is about 8℃, gear 3 temperature is about 6~7℃, gear 4 temperature is about 5℃, gear 5 temperature is about 4℃, gear 6 temperature is about 3℃, and gear 7 temperature is about 2℃.
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 users need to choose different gears to use in different seasons. Refrigerator thermostat should be turned on at low level in summer and at high level in winter. When the ambient temperature is high in summer, it should be used in weak gear 2 and 3, and when the ambient temperature is low in winter, it should be used in strong gear 4 and 5.
According to the seasonal changes, the reasons for adjusting the refrigerator switch are:
In summer, the ambient temperature is high (up to 30℃). If the freezing room temperature is below-18℃, the temperature difference between inside and outside is large, and it is difficult to reduce the freezing room temperature by 1℃. Moreover, it will accelerate the loss of cold air through the insulation layer and door seal of the cabinet, so that the startup time is long and the shutdown time is short.
If you change to the weak gear (2nd gear and 3rd gear) at this time, the current start-up time of the refrigerator will be obviously shortened, the compressor wear will be reduced and the service life will be prolonged. Therefore, when it is hot in summer, the temperature control will be adjusted to a weak level. When the ambient temperature is low in winter, if the thermostat is still set at a weak position and the temperature difference between inside and outside is small, it will be difficult for the compressor to start, and the refrigerator with single refrigeration system may be frozen in the freezing room.
The correct setting temperature of refrigerator freezer is 5-7 degrees, which can not only ensure the fresh-keeping effect of food, but also avoid the waste of resources caused by low temperature setting.
