Abstract

This invention refers to a air cooling frequency change refrigerator and control method, which contains refrigeration system, casing and control system which makes the refrigerator operation in maximum refrigerating mode, maximum energy efficiency ratio mode and most power saving mode according to the demand in different refrigeration stage by collecting and judging the information of temperature difference and temperature reducing rate.

Description

technical field [0001] The invention relates to a refrigerator and an air-cooled frequency conversion control method for the refrigerator. Background technique [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 The match in the refrigerator is 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. . Contents of the invention [0003] The ...
