The invention discloses a defrosting control method and system based on an air-cooled refrigerator, and relates to the technical field of refrigerator defrosting. In the defrosting stage of an evaporator, when Te is less than or equal to Ha, a heater is controlled to perform heating by 100% heating power; when Te is less than or equal to Hb and greater than Ha, the heater is controlled to performheating by 50% heating power; when Te is less than or equal to Hc and greater than Hb, the heater is controlled to perform heating by 25% heating power; and after the defrosting is completed, a defrosting temperature threshold value Ha and a defrosting temperature threshold value Hb are modified according to deltaTc. An evaporator temperature Te is mentioned in the defrosting process through an evaporator temperature sensor, and a heater drive module adjusts the heating power of the heater according to the range of Te; and when the defrosting is completed, the evaporator temperature sensor monitors an evaporation temperature Td after defrosting, the defrosting temperature threshold value Ha and the defrosting temperature threshold value Hb are adjusted, the clean defrosting of the evaporator is ensured, the waste of energy consumption is reduced, and energy is saved.
Description
technical field [0001] The invention belongs to the technical field of defrosting refrigerators, and in particular relates to a defrosting control method and system based on an air-cooled refrigerator. Background technique [0002] The air-cooled refrigerator is also called a frost-free refrigerator. Its working principle is: the high-temperature air from the outside flows through the evaporator installed inside the refrigerator for heat exchange, so that the temperature of the air after the heat exchange is lowered, and the temperature has been lowered after the heat exchange. The cold air is blown into the refrigerator compartment through the air duct, so as to achieve the purpose of cooling. During the above working process, the moisture in the high-temperature air will condense and frost on the surface of the cold evaporator when it meets the cold evaporator. As the use time is longer, it will easily lead to poor cooling effect, so it is necessary to evaporator from time...
