The invention relates to a pure electric vehicle type air conditioning system calibration method. The method includes the steps that firstly, the air conditioner system oil circulation rate is detected; 2, refrigerant flow changes of a passenger compartment refrigerating loop and a battery cooling loop are detected; and 3, calibrating the pure electric vehicle type air-conditioning system according to the oil circulation rate test result of the air-conditioning system and the refrigerant flow change result of each loop. According to the method, a basis is provided for calibration of the air conditioning system of the whole vehicle through changes of the oil circulation rate and the refrigerant flow: if a working condition of poor oil circulation rate exists, the corresponding working condition is avoided or a transition working condition is set according to a rack calibration result when the air conditioning system is calibrated in a real vehicle so as to ensure that the oil circulation rate is within an acceptable range; the purposes of prolonging the service life of the compressor and reducing the energy consumption of the air conditioner are achieved; if the flow distribution is unreasonable, the refrigerant flow is reasonably distributed by controlling the opening degree of the electronic expansion valve, and the situation that the comfort is affected due to the fact that a passenger compartment is too cold or not cold is prevented.
本发明是一种纯电车型空调系统标定方法。包括:步骤一、检测空调系统油循环率;步骤二、检测乘员舱制冷回路和电池冷却回路的制冷剂流量变化。步骤三、通过空调系统的油循环率测试结果和各回路的制冷剂流量变化结果对纯电车型空调系统进行标定。本发明通过油循环率和制冷剂流量的变化,为整车空调系统的标定提供依据:如存在油循环率不良的工况,在实车标定空调系统时依据台架标定结果规避改相应工况或设置过渡工况以保证油循环率处于可接受区间,从而改善空调系统运行状态,达到延长压缩机使用寿命、降低空调能耗的目的;如存在流量分配不合理的情况,则通过控制电子膨胀阀开度合理分配制冷剂流量,防止出现乘员舱过冷或不冷等影响舒适度的情况。
