电动涡旋压缩机在电动汽车热泵空调系统中的应用发展迅速,作为系统工作的核心部件,电动涡旋压缩机的设计应充分考虑其使用需求.针对压缩机的润滑与回油问题,热泵空调系统与普通的制冷空调系统中又存在着差别.文章从系统内各零部件出发,探讨充分考虑润滑与回油时,热泵系统各部件的设计方法.在流程隔板中应设置适当的回油孔,并合理设计回油孔位置与尺寸,以保证充分润滑与回油,提高压缩机的可靠性与系统的性能.%The application of electric scroll compressor in electric vehicle's heat pump air conditioning system is developing rapidly. As the core component of the system, the design of electric scroll compressor should fully consider its use requirements. For the lubrication and oil return problems of the compressor, there are differences between the heat pump air conditioning system and the common refrigeration air conditioning system. Starting from all parts in the system, this paper discusses the design method of all parts of the heat pump system when lubrication and oil return are fully considered.Appropriate oil return holes should be set in the process partition, and the position and size of the oil return holes should be reasonably designed to ensure sufficient lubrication and oil return and to improve the reliability of the compressor and the system performance.
