The invention relates to a refrigerating speed control method, device and system for a non-independent refrigerating unit of a refrigerator car, and belongs to the technical field of refrigerator car temperature control. The method comprises the steps that the current state of a vehicle, the current set temperature of a refrigerator and the temperature in a compartment are obtained; when the temperature in the compartment is higher than the set temperature and is in a parking state, the rotating speed of an engine is adjusted according to the difference value between the temperature in the compartment and the set temperature; and when the temperature in the compartment is higher than the set temperature and is in a running state, the engine speed is not lower than the set speed threshold. The device comprises a controller and a memory, wherein the controller is used for executing the computer instructions used for implementing the method in the memory. The system comprises a mode selection module, a manual rotating speed increasing device and an engine controller, and the engine controller adopts an automatic rotating speed increasing mode or a manual rotating speed increasing mode to adjust the rotating speed of an engine according to mode information. The compartment can be rapidly cooled, time and labor are saved, safety risks do not exist, stability is good, and accuracy is high.
