How long can the car refrigerator keep warm after the power is cut off?
After the refrigerator is cut off from the power supply, the insulation layer and box sealing condition determine the insulation effect of the refrigerator, which is specifically affected by the following factors:
1.How many items are placed inside, and items with a relatively large specific heat capacity such as water can be kept warm longer than if nothing is placed. The more items placed inside, the longer the keeping time;
2.the lower the ambient temperature, the longer the refrigerator will keep warm.
The time and frequency of opening the door are affected. Not opening it after a power outage or shortening the time and frequency of opening the door is beneficial to the insulation of the box.
