The refrigerator uses the evaporator to exchange heat inside the refrigerator, thereby reducing the temperature inside the refrigerator. During the refrigeration and cooling process of the refrigerator, since its temperature is much lower than the external ambient temperature or even reaches subzero, condensation water is likely to appear inside the refrigerator and on the evaporator and even freeze to form frost. After long-term use, that is, as the accumulation of ice and frost increases, the cooling effect of the refrigerator will be reduced, resulting in a waste of energy consumption.
