Problems solved by technology

Since the temperature sensing error of the magnetic switch itself is within ±2°C, this kind of scheme design is likely to result in poor consistency of the whole machine due to the poor consistency of the magnetic switch.

Abstract

The invention relates to a direct-cooling refrigerator draught fan control method and system and a refrigerator. The method includes the steps that an environment temperature t1 and a refrigerating chamber temperature t2 are collected in real time, and the currently-set operation mode of the refrigerator and the operation state of a compressor are detected; and the operation state of a draught fan in a refrigerating chamber is controlled according to the environment temperature t1, the refrigerating chamber temperature t2, the currently-set operation mode of the refrigerator and the operation state of the compressor. The draught fan is arranged in the refrigerating chamber of the refrigerator of a direct-cooling structure, the operation mode of the draught fan is affected by the environment temperature, the refrigerating chamber temperature, different gear functions set by a user and the operation state of the compressor, the operation state of the draught fan is reasonably controlled according to the above factors, the refrigerating chamber can be rapidly cooled, the quick-freezing effect of a freezing chamber can also be achieved, and the effect of low energy consumption in the environment temperature of 25 DEG C required by the national standard can be achieved.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a direct cooling refrigerator fan control method system and a refrigerator. Background technique [0002] At present, when the freezing and refrigerating evaporators of direct-cooling refrigerators are matched and designed, they are often matched at a certain ambient temperature. The ratio of the cooling capacity of the freezer cannot be adjusted arbitrarily, and is completely determined by the size of the refrigeration system pipeline and the heat load. This will lead to an inappropriate ratio of evaporation area between the freezer and refrigerator at some ambient temperatures, resulting in the inability to meet some experimental requirements, such as excessive power consumption or high and low ambient temperature storage does not meet the requirements, and the speed of quick cooling and quick freezing is slow. Wait. The cooling method of the direct cooling refrigerator...
