摘要: 基于压缩腔动网格CFD仿真,结合R454B制冷剂特性从型线方程、内容积比、吸排气形式等角度研究了低背压涡旋压缩机型线参数对泵体性能、轴向气体力的影响,在原代数螺旋型线的基础上优化出一种基于圆渐开方程形式的非对称吸气型线,通过测试验证,新型线相比于原型线整机性能提升约1%~1.5%。

Abstract: Based on the dynamic grid CFD simulation of the compression chamber and combined with the characteristics of R454B refrigerant, the influence of low back pressure vortex compressor model line parameters on pump performance and axial gas force was studied from the perspectives of line equation, content product ratio, and suction and exhaust form. On the basis of the original algebraic spiral profile, an asymmetric suction profile based on the circular involute equation form was optimized. Through testing and verification, the new line improved the overall performance by about 1%~1.5% compared to the prototype line.
