1. Understand the temperature range of double freezers: Different brands and models of double freezers may have slightly different temperature ranges. Generally, the refrigerator temperature is 0- 10℃, and the freezer temperature is below-18℃. So you should consult the product manual first to know the best temperature range of refrigerator and freezer.
2. Temperature controller: There is a temperature controller on the upper or side of the double freezer, and the temperature is usually set by knob or numerical control display panel. When adjusting the temperature of the double freezer, you must first turn on the thermostat, and then adjust the temperature according to the suggestions in the manual. Some double freezers have automatic temperature control function, which can automatically adjust the temperature according to the surrounding environment and use conditions.
3. Location of food containers: In order to ensure the cold storage and freezing of food, the food containers in the double freezer need to be placed in the correct position. For example, fresh food should be kept in the coldest place in the refrigerator to ensure that they stay fresh. At the same time, the food in the freezer should be placed separately to ensure air circulation and maintain an appropriate temperature.
It should be noted that if the temperature of the double freezer is too high or too low, it may have a negative impact on the freshness and shelf life of food. Therefore, the temperature of double freezers should be checked regularly and adjusted as needed. In addition, in order to keep the temperature stable, it is necessary to avoid opening the freezer door frequently.
