The invention relates to a control method and system of an inverter compressor, and a refrigerator. The control method of the inverter compressor comprises the steps of setting frequency raising conditions of the inverter compressor; acquiring operating parameters of the refrigerator after the inverter compressor starts; and determining whether to raise the current operating frequency of the inverter compressor according to the refrigerator operating parameters and the frequency raising conditions of the inverter compressor. According to the control method and system of the inverter compressor, and the refrigerator, operating gears of the inverter compressor can be automatically adjusted according to a load and a practical refrigeration effect of the refrigerator in the operating process of the inverter compressor of the refrigerator; a refrigerating chamber and a freezing chamber can automatically work in appropriate operating modes; not only is the customer use more convenient and fast, but also the slow cooling problem due to a long term of operating at a certain rotation speed of the refrigerator is solved; the refrigeration effect of the refrigerator is effectively improved, and the service life of the refrigerator is effectively prolonged; and at the same time, the energy consumption is lowered, and the market competitiveness of the refrigerator is improved.
Description
technical field [0001] The invention relates to the field of refrigerator control, in particular to a method for controlling a variable frequency compressor, a control system and a refrigerator. Background technique [0002] In the prior art, the frequency conversion compressor of the refrigerator usually has multiple rotation speeds, and the rotation speed of the frequency conversion compressor can be divided into different gears according to different ambient temperatures and cooling requirements. In actual operation, the operating frequency of the inverter compressor of the refrigerator is controlled according to the temperature set by the user, the current ambient temperature and the cooling demand. The disadvantage of the existing technology is that the cooling capacity and effect of the refrigerator are not only related to the current ambient temperature and cooling demand, but also related to the load such as food put in the refrigerator. For example, when the ambien...
