Control method, control device and refrigerator

Abstract

The invention provides a control method, a control device and a refrigerator. Wherein, the control method includes dividing the ambient temperature into multiple temperature segments, the multiple temperature segments corresponding to the multiple speed gears of the frequency conversion compressor respectively; and determining the corresponding speed gear according to the temperature range where the current ambient temperature is located, and Adjust the speed of the inverter compressor to the corresponding speed gear. Through the technical solution of the present invention, it is possible to divide the ambient temperature into multiple temperature sections, each ambient temperature section corresponds to a different reference speed, and the speed is controlled according to the change of the ambient temperature, thereby improving the best matching between the inverter compressor and the refrigerator , to improve the best preservation effect for food, and greatly enhance the flexibility of refrigerator control.

Description

technical field [0001] The present invention relates to a control technology, in particular to a control method, a control device and a refrigerator. Background technique [0002] The refrigeration compressor is the core of the refrigeration system. The frequency conversion compressor can automatically adjust the operating power of the refrigerator, which is an important means of saving energy for the refrigerator. However, the speed control of inverter compressors on the market is relatively mechanical, and the change of the compressor speed of the entire refrigerator is only controlled by the load change of the cabinet, without considering the influence of the ambient temperature on the speed, and the influence of factors such as the user opening and closing the door. The influence of the load change of the cabinet, and the user's requirements for the noise of the compressor when the refrigerator is running at night have not been considered, and intelligent frequency conve...

However, the speed control of inverter compressors on the market is relatively mechanical. The change of the compressor speed of the entire refrigerator is only controlled by the load change of the cabinet, without considering the influence of the ambient temperature on the speed, and the influence of factors such as the user opening and closing the door. The influence of the load change of the cabinet, not to mention the user's requirements for the noise of the compressor when the refrigerator is running at night, did not really realize the intelligent frequency conversion control
