Problems solved by technology

[0002] In the current existing technology, traditional refrigerators are matched according to certain standard requirements under specified working conditions, but in practical applications, refrigerators are rarely used under matching working conditions, that is to say, in practical applications Matches for medium fridges are often not optimal
In particular, the traditional refrigerator only performs frequency conversion adjustment based on the temperature inside the refrigerator as the detection object, without comprehensive consideration of various working conditions of the refrigerator, and cannot effectively guarantee that the refrigerator will always work in the best matching state under various working conditions.
