Abstract

A compressor variable frequency control system applied to a refrigerator is used for being arranged in the refrigerator provided with a refrigerator door and a compressor, and comprises a mechanical change-over switch, a sensing unit, a comparing unit and a processing unit, wherein the mechanism change-over switch is provided with a position change stroke which is provided with a low-critical temperature setting point and a high-critical temperature setting point; the sensing unit is used for sensing first operation stop time when the compressor stops operating; the comparing unit is provided with second operation stop time, and is used for comparing the first operation stop time with the second operation stop time when the mechanical change-over switch is switched to the high-critical temperature setting point; and the processing unit is provided with an operation frequency compensation meter comprising a corresponding relationship of first and second operation stop time difference and a first compensation frequency, and is used for deciding to increase or decrease the frequency of the compressor according to the magnitudes of the first and second operation stop time.

Description

technical field [0001] The invention relates to a compressor frequency conversion control system applied to a refrigerator, in particular to a compressor frequency conversion control system applied to a refrigerator which determines frequency up and down frequency according to the stop running time of the compressor. Background technique [0002] With the advancement of science and technology, in recent years, household refrigerated refrigerators have a trend of large capacity and low power consumption. In order to improve the energy efficiency of household refrigerators, the industry uses the characteristics of low speed, low input power, and low energy consumption of inverter compressors. , to save energy and electricity, and then achieve the purpose of improving energy efficiency. Among them, for the control of the temperature of the refrigerating chamber and the freezing chamber of the refrigerator, temperature sensors are installed in the refrigerating chamber and the f...
