变排量压缩机汽车空调制冷系统节流元件的配置

摘要

对变排量压缩机与定排量压缩机加以比较，在分析变排量压缩机和热力膨胀阀汽车空调制冷系统以及变排量压缩机和节流管汽车空调制冷系统基础上，提出了变排量压缩机和电子膨胀阀组成的汽车空调制冷系统，并对其系统特性加以分析，提出其控制方案和控制算法。%The comparison between variable displacement compressor and fixed displacement compressor is made in this paper. On the basis of analyzing the variable displacement compressor and automotive air conditioning refrigerating system with thermodynamic expansion valve as well as the variable displacement compressor and automotive air conditioning refrigerating system with throttling tube, the automotive air conditioning refrigerating system composed of variable displacement compressor and electronic expansion valve is introduced in this paper, analysis of this system characteristic, its control method and control algorithm are described also.
