The gas pipe or the liquid pipe is not provided with a control valve, the refrigerant flow of the liquid pipe or the gas pipe under the target opening degree is controlled through the unloading opening degree on the unloading pipeline, for example, if the maximum opening degree value is 50 steps and the target opening degree is 35 steps, the refrigerant flow flowing through the gas pipe or the liquid pipe when the refrigerant flow on the gas pipe or the liquid pipe is 35 steps is controlled through controlling the unloading opening degree on the unloading pipeline to be 15 steps.
Specifically, the unloading opening degree of the unloading pipeline is calculated according to Pi & ltPo & gt-Pn & lt, wherein Po is the maximum opening degree value of the unloading valve, and Pn is the target opening degree of the air pipe or the liquid pipe or the unloading pipeline.
In this embodiment, the difference between the maximum opening value and the target opening is calculated, and the difference is used as the unloading opening of the unloading pipeline, so that the calculation method is simple and the accuracy is high.
