摘　　要：为了解决双向旋转斜盘式活塞压缩机在汽车空调温控系统中因润滑油充注量不当而导致的制冷效率降低和潜在故障问题,对润滑油充注策略进行优化,以提高系统运行的效率和稳定性。分析了润滑油充注量不足或过量可能导致的各种问题,探究了在不同压缩机转速条件下,不同润滑油充注量对制冷性能的具体影响。通过对比试验发现,当润滑油充注量被精确控制在390±20~535±20 mL的范围内,空调系统能够在变化的工作状态下保持最优性能,并显著降低由润滑油不足带来的风险;最佳的润滑油与制冷剂的配比约为12%,并提出了一系列技术措施,这些措施旨在提高斜盘式活塞压缩机的可靠性,为斜盘式活塞压缩机在广泛的工程应用中的润滑策略提供了理论依据和实践指导。In order to solve the problem of cooling efficiency reduction and potential fault due to improper lubricant charge of the swashplate compressor in the temperature control system of vehicle air conditioning system,the compressor was optimized according to the lubricant charging strategy in order to improve the operating efficiency and stability of the system.The problems that may be caused by insufficient or excessive lubricant charge was analyzed,and the specific effects of different lubricant charge on cooling performance under different compressor speeds were investigated.Through comparative tests,it is found that when the lubricant charge is precisely controlled in the range of 390±20 mL to 535±20 mL,the air conditioning system can maintain the optimal performance under variable working conditions and significantly reduce the risk caused by insufficient lubricant.The best ratio of lubricant to the refrigerant is about 12%,and a series of technical measures was proposed.These measures aim to improve the compressor reliability,and provide theoretical basis and practical guidance for the lubrication strategy of the swashplate compressor in wide engineering applications.
