Abstract

The invention discloses a compressor control method. The compressor control method comprises the steps of acquiring compression status information, based on the status information, determining the compressor current status, when the compressor is in a power pre-protection status, based on the current status, determining a rotation speed regulating mode, based on the determined rotation speed regulating mode, regulating the compressor rotation speed. The compressor control method can use different speed regulating modes for different over-power situations to achieve the power protection, and avoids the compressor damage. The invention further discloses a compressor control device and a refrigerator.

Description

technical field [0001] The invention belongs to the technical field of electric appliance manufacturing, and in particular relates to a compressor control method, a compressor control device and a refrigerator. Background technique [0002] With the popularization of frequency conversion technology, there are more and more frequency conversion refrigerators on the market. As the core of the frequency conversion refrigerator system, the frequency conversion compressor directly determines the performance of the frequency conversion refrigerator. When the inverter compressor is working, there is a maximum power limit. If the power of the compressor exceeds this limit, the life of the compressor will be reduced and the performance of the compressor will be damaged. For example, the maximum working power of an inverter compressor is 230W. If the refrigerator is in a high-temperature environment and there are many things in the refrigerator, the power of the compressor may reach m...
