Abstract
This invention provides a method and apparatus for controlling the speed of a refrigerator refrigeration fan. The method includes: in the current operating cycle, detecting whether the refrigerator evaporator temperature reaches a target temperature before the refrigerator refrigeration fan reaches a preset operating time, and obtaining a detection result; determining a control strategy for the speed of the refrigerator refrigeration fan based on the detection result; and controlling the speed of the refrigerator refrigeration fan according to the control strategy. This solves the technical problem in the prior art where the speed control of the refrigerator refrigeration fan does not conform to the actual operating conditions of the refrigerator, resulting in the refrigeration fan running at high speed for extended periods, high fan noise, and thus a poor user experience.
