Why doesn't the mini fridge shut down?

There are two possibilities for non-stopping:
　Du　 1. There is a problem with the temperature sensor of the indoor unit.
　　2. The China Mini Fridge factory capacity of the air conditioner is too small. If the refrigeration capacity becomes smaller, please ask professional maintenance personnel to find the cause (fluorine leakage or other). The cooling capacity is relative to the room size and heat load.
　　3. The room heat preservation performance is not good or the indoor heat load becomes large (too many electric appliances are turned on).
working principle:
　　 Air conditioners are divided into single-cold air conditioners and dual-purpose air conditioners. The working principle is the same. In the past, most common refrigerants used in air conditioners were Freon. The characteristic of Freon is that when it changes from a gaseous state to a liquid state, it releases a lot of heat. When it changes from liquid to gas, it will absorb a lot of heat. (That is, first absorb heat and vaporize and then liquefy to release heat) The air conditioner is designed according to this principle.
