| 为解决新能源汽车空调用涡旋压缩机在热泵工况下常出现的欠压缩以及排气温度过高的问题，课题组基于一款应用于新能源汽车的涡旋压缩机，对其型线和几何结构特征进行分析并优化涡旋型线，以改善热泵工况下涡旋压缩机的工作特性。在相同几何排量的条件下优化压缩机型线参数，并在不同的热泵工况下对改进前、后的压缩机性能进行理论计算对比。结果表明：优化后的涡旋压缩机能够改善热泵工况下的欠压缩，涡旋压缩机排气温度降低了10%~25%；而且减小压缩机功耗和增大制热量使系统制热性能系数提高了15%。优化方法达到了节能的目的。 |

| In order to solve the problems of under compression and high discharge temperature of the scroll compressor used in new energy vehicle air conditioning under the heat pump conditions, the profile and geometric structure of the scroll compressor applied to new energy vehicles were analyzed and the scroll profile was optimized to improve the working characteristics of the scroll compressor under heat pump conditions. The scroll compressor profile was optimized under the same geometric displacement, and the system performance of the two scroll compressors before and after improvement were compared by theoretical calculation under different heat pump conditions. The results show that the optimized scroll compressor can improve the under compression of the heat pump and reduce the discharge temperature by 10% to 25%. The heating coefficient of system performance increases by 15% through reducing the power consumption and increasing the heat capacity. The optimization method achieves the purpose of energy saving. |
