The invention relates to the field of defrosting treatment, and particularly relates to a control method for natural air return defrosting in refrigeration and a control system for natural air return defrosting in refrigeration. The control method comprises the following steps: starting air return defrosting; acquiring a real-time environment temperature according to a signal of stopping refrigeration of a refrigeration chamber; determining the minimum time length of the air return defrosting and the maximum time length of the air return defrosting according to the real-time environment temperature; generating a shutdown signal of a refrigeration fan according to the time length of the air return defrosting, the minimum time length of the air return defrosting, the maximum time length of the air return defrosting and a temperature of a refrigeration defrosting sensor; determining a shutdown time of the refrigeration fan according to the real-time environment temperature; and recording a shutdown time length of the refrigeration fan in real time, and exiting the air return defrosting and carrying out refrigeration in the refrigeration chamber after the shutdown time length of the refrigeration fan is greater than or equal to T(shutdown). According to the control method and the control system, the air return defrosting time is limited, complete melting of a surface frost layer of an evaporator is guaranteed, and the problem of long-time no refrigeration of the refrigeration chamber due to that the temperature of the refrigeration defrosting sensor cannot achieve a start-up temperature for a long time is avoided.
Description
technical field [0001] The invention relates to the field of defrosting treatment, in particular to a control method for refrigerated natural return defrosting and a refrigerated natural return defrosting control system. Background technique [0002] The existing dual-system air-cooled refrigerator freezer generally adopts natural return weathering to defrost, that is, after the end of refrigeration and refrigeration, the solenoid valve switches but the refrigeration fan continues to run, and the heat carried by the refrigeration return air is used to heat the frost layer on the surface of the evaporator To achieve the purpose of defrosting, a temperature sensor is generally installed on the outlet of the evaporator in the refrigerator to control the defrosting process of the refrigerator. Only when the temperature reaches the set temperature, the refrigerator can supply cooling to the refrigerator again. . The existing defrosting is mainly controlled by the temperature of ...
