Abstract

The invention relates to the field of defrosting control, in particular to an air-cooling refrigerator, a defrosting control method thereof, a control system and a controller. High-temperature air ofthe air-cooling refrigerator conducts heat exchange with an evaporator in an air dust and is delivered into a refrigeration chamber through running of a draught fan. When the evaporator is gradually frosted, heat exchange air receives frosting resistance of the evaporator during flowing, and the draught fan runs slowly. Based on the principle, the rotational speed of the draught fan can directly reflect the frost quantity of the evaporator. The actual frost quantity of the evaporator can be directly judged by judging the rotational speed of the draught fan. When it is sensed that the rotational speed of the draught fan is reduced to a certain low rotational speed, it means that the evaporator frosts much, a defrosting assembly needs to be started for defrosting in time. Thus, the problemsthat large energy consumption and poor heat preservation effect caused by defrosting in advance or delayed defrosting through a traditional control method can be solved, and the energy saving and heatpreservation effects of the air-cooling refrigerator are improved.

Description

technical field [0001] The invention relates to the field of defrosting control, in particular to a defrosting control method for an air-cooled refrigerator, a defrosting control system for an air-cooled refrigerator, a controller and an air-cooled refrigerator. Background technique [0002] Air-cooled refrigerators, also known as frost-free refrigerators, use air for cooling. When high-temperature air flows through the built-in evaporator, the high-temperature air directly exchanges heat with the low-temperature evaporator. The air temperature decreases, and the cooled air is blown into the refrigerator through the fan. Achieve refrigeration. [0003] Since there is always water vapor in the air, the water vapor will condense when it is cold. In the process of continuous heat exchange, the water vapor will gradually frost on the evaporator. In order to make the evaporator work normally, it is necessary to defrost the evaporator. At present, there are multiple conditions fo...
