The invention provides a vehicle air conditioner refrigerant charge defining method, device and equipment and a storage medium, and belongs to the technical field of vehicle air conditioner refrigeration. Executing a test process, filling the refrigerant into the test bed, recording process data of the refrigerant filling amount, drawing a relational graph of the air conditioner high pressure and the refrigerant filling amount by taking the refrigerant filling amount as an X axis and the high pressure of the air conditioner system as a Y axis, searching an area where the high pressure of the air conditioner system tends to be stable in the graph, and defining an upper limit value and a lower limit value of the refrigerant filling amount; calculating to obtain the optimal refrigerant charge quantity; a medium pressure protection pressure and a medium pressure protection exit pressure are defined. According to the method, the relational graph of the air conditioner high pressure and the refrigerant charge is drawn, and the upper limit value and the lower limit value of the refrigerant charge can be accurately found. Compared with traditional experience judgment or rough estimation, the method is more accurate, and it can be ensured that the performance of the refrigeration system is optimal.

    本发明提供一种车辆空调制冷剂充注量定义方法、装置、设备及存储介质,属于车辆空调制冷技术领域,执行充注量试验进程;执行试验进程,将制冷剂充注试验台架,记录制冷剂充注量过程数据,并以制冷剂充注量为X轴,以空调系统高压压力为Y轴,绘制空调高压与制冷剂充注量的关系图,寻找图中空调系统高压趋于平稳的区域,定义制冷剂充注量的上限值和下限值;计算得到制冷剂最佳充注量;定义中压保护压力与中压保护退出压力。本申请的方法绘制了空调高压与制冷剂充注量的关系图,能够准确地找到制冷剂充注量的上限值和下限值。相比传统的经验判断或粗略估算更为精确,可以确保制冷系统的性能达到最优。
