For the problem of serious exhaust loss of miniature oil-free scroll air compressor with asymmetric working chambers, the design method of the exhaust port was given according to the inner volume ratio. The effects of the internal flow field characteristics and performance variations of the scroll compressor with asymmetrical chambers under different clearances and altitude were analyzed by CFD method and verified experimentally. The results show that the new exhaust port can reduce the amount of over-compression by 17.85% and reduce exhaust losses. When the radial clearance increases from 10 μm to 30 μm, the compressor volumetric efficiency decreases from 89.68% to 16.02% and the isentropic efficiency decreases from 78.69% to 32.84%. Experimental results on main performance such as flow and power etc. show that the maximum error between the experimental mass flow rate and the simulation result is 9.09%, and the maximum error of the power at an exhaust pressure of 0.26 MPa is 8.90%. The relevant results are of reference significance for reducing the exhaust loss of scroll compressors with asymmetric working chambers.

针对非对称腔微型无油涡旋空气压缩机排气损失较为严重的问题,给出了根据2个工作腔的内容积比设计排气孔的方法。利用CFD仿真方法,分析了不同间隙和海拔高度下非对称腔涡旋压缩机内部流场特性和性能变化规律,并进行了试验验证。结果表明:新设计的排气孔能够减少17.85%的过压缩量,减少了排气损失;当径向间隙从10 μm增大到30 μm时,压缩机容积效率从89.68%下降到16.02%,等熵效率从78.69%降低到32.84%;对流量、功率等主要性能参数进行试验,得到试验质量流量与模拟结果的最大误差为9.09%,功率在排气压力为0.26 MPa时的最大误差为8.90%。相关结果对于降低非对称腔涡旋压缩机的排气损失有参考意义。

针对非对称腔微型无油涡旋空气压缩机排气损失较为严重的问题,给出了根据2个工作腔的内容积比设计排气孔的方法。利用CFD仿真方法,分析了不同间隙和海拔高度下非对称腔涡旋压缩机内部流场特性和性能变化规律,并进行了试验验证。结果表明:新设计的排气孔能够减少17.85%的过压缩量,减少了排气损失;当径向间隙从10 μm增大到30 μm时,压缩机容积效率从89.68%下降到16.02%,等熵效率从78.69%降低到32.84%;对流量、功率等主要性能参数进行试验,得到试验质量流量与模拟结果的最大误差为9.09%,功率在排气压力为0.26 MPa时的最大误差为8.90%。相关结果对于降低非对称腔涡旋压缩机的排气损失有参考意义。

For the problem of serious exhaust loss of miniature oil-free scroll air compressor with asymmetric working chambers, the design method of the exhaust port was given according to the inner volume ratio. The effects of the internal flow field characteristics and performance variations of the scroll compressor with asymmetrical chambers under different clearances and altitude were analyzed by CFD method and verified experimentally. The results show that the new exhaust port can reduce the amount of over-compression by 17.85% and reduce exhaust losses. When the radial clearance increases from 10 μm to 30 μm, the compressor volumetric efficiency decreases from 89.68% to 16.02% and the isentropic efficiency decreases from 78.69% to 32.84%. Experimental results on main performance such as flow and power etc. show that the maximum error between the experimental mass flow rate and the simulation result is 9.09%, and the maximum error of the power at an exhaust pressure of 0.26 MPa is 8.90%. The relevant results are of reference significance for reducing the exhaust loss of scroll compressors with asymmetric working chambers.
