摘　　要：使用电子膨胀阀(EXV)试验确定热泵空调制冷和制热的最优开度,在此基础上,采用CFD的方法对节流管和电子膨胀阀进行仿真分析,确定节流管的选型。进一步进行台架试验,与电子膨胀阀做对比分析,最后在实车上进行夏季制冷和冬季采暖试验。试验表明,通过CFD仿真分析,可以对热泵节流管进行选型,车辆可以满足夏季制冷需求和冬季-8℃以上的采暖需求。The electronic expansion valve test is used to determine the optimal opening of the heat pump.Based on this,CFD is used to simulate and analyze the orifice tube and the electronic expansion valve to determine the type of the orifice tube.Compare and analyze orifice tube with the electronic expansion valve by bench test and finally do the cooling and heating test by road test.The test shows that type of orifice tube can be selected by CFD,and the vehicle can meet the cooling demand in summer and the heating demand above-8℃in winter.
