摘　　要：从研究涡旋压缩机工作腔和背压腔的泄漏、热和能量转换入手，建立了一个自调背压腔压力平衡系统的热力学模型．此模型不仅能预测轴向平衡系统涡旋压缩机的工作过程，而且能为背压孔的优化设计提供计算依据．Analyzed are the Oil and air leakage in the working volume and the heat and mass transfer betwween the compressed volume and backpressure chamber. An analytical model is developed to quantify the thermodynamic process of scroll compressor with selfadjusting backpressure and an axial counterbalance system. It also services the purpose for optimizing the adjustment of backpressure openings.
