摘　　要：建立了变壁厚涡旋压缩机型线方程。在变壁厚条件下针对某一款电动车空调用涡旋压缩机对其容积特性、动力特性和热力学特性进行计算,并与等壁厚涡旋压缩机进行比较。计算结果显示:同款变壁厚后的涡旋压缩机吸气容积提升7.90%,压缩过程的容积变化率减小,轴向气体力较等壁厚稍有增大,同时相比于等壁厚涡旋压缩机制冷量和制冷COP分别提高15.55%和41.68%。A profile equation for a variable wall thickness scroll compressor was established.The volumetric,dynamic and thermodynamic characteristics of a certain type of electric vehicle air conditioner scroll compressors were calculated under variable wall thickness conditions,and compared with an equal wall thickness scroll compressor.The calculation results show that the volumetric suction of the same scroll compressor with the optimized wall thickness was increased by 7.90%,the volume change rate of the compression process was decreased,the axial force was increased slightly,at the same time,the cooling capacity and refrigeration COP were increased by 15.55%and 41.68%,respectively.
