Example Embodiment
[0027] The core of the present invention is to provide a control method for the electronic expansion valve of an automobile air conditioning system. The relatively constant opening degree can ensure that the opening degree of the electronic expansion valve can be in a stable state, so that the expansion valve in the initial stage is in a stable working state, thereby It can effectively avoid the impact of large disturbances on the expansion valve, ensure the normal and efficient operation of the system, and effectively improve the energy-saving effect of the system. Hereinafter, this embodiment will be described in detail with reference to the drawings in the specification.
[0028] See figure 1 , This figure shows a flowchart of the control method of the electronic expansion valve of the automobile air conditioning system according to the first embodiment.
[0029] Such as figure 1 As shown, after the compressor is started, the compressor speed signal is obtained in real time, and...
