The invention discloses an automobile air conditioner heat pump system control method. The method comprises the steps that the working mode of an air conditioner heat pump system is selected, and the target temperature is set; the refrigerating capacity or heating capacity needed in the compartment is obtained; solving the circulation efficiency of the system, and obtaining the valve opening degree of the system, the rotating speed of a compressor and the superheat degree of an evaporator outlet; the air outlet temperature of the heat exchanger and the superheat degree of an evaporator outlet are read, and the valve opening degree and the rotating speed of a compressor are adjusted through a model prediction controller; judging the automobile running state after the valve opening and the compressor rotating speed are adjusted and judging whether the automobile external state is changed or not; whether the working mode of the system is switched or not is judged, if the working mode is switched, the compressor needs to be stopped working, an expansion valve is opened to the maximum, and a reversing valve is switched; otherwise, continuing to execute the next step; whether the system needs to be closed or not is judged, if yes, a compressor is closed, and an expansion valve is opened to the maximum; otherwise, the working mode of the air conditioner heat pump system is reselected, and the target temperature is set.
本公开揭示了一种汽车空调热泵系统控制方法,包括:选择空调热泵系统的工作模式并设定目标温度;获取车厢内所需制冷量或制热量;求解系统的循环效率,获得系统的阀门开度和压缩机转速以及蒸发器出口过热度;读取换热器的出风温度和蒸发器出口过热度并通过模型预测控制器对阀门开度和压缩机转速进行调节;判断阀门开度和压缩机转速调节后的汽车运行状态以及判断汽车外部状态是否改变;判断系统是否切换了工作模式,若切换了工作模式,则需停止压缩机工作,并将膨胀阀开至最大,以及切换换向阀;否则继续执行下一步骤;判断是否需要关闭系统,若是,则将压缩机关闭,以及将膨胀阀开至最大;否则重新选择空调热泵系统的工作模式并设定目标温度。
