摘　　要：为进一步促进超临界CO_2无水染色系统的产业化推广,针对染色系统的能耗问题,采用有效能分析法对系统耗能情况进行计算分析,建立了系统各单元有效能平衡方程,采用PR方程计算工质未知参数,采用余函数法计算系统有效能损失,重点分析了染色温度对加热/染色单元和节流压力对制冷单元有效能效率的影响。计算结果表明:加热/染色单元与制冷单元有效能损失量总和占系统输入有效能的60%以上,是系统节能改进的关键单元。染色温度由353.15 K升至393.15 K,加热/染色单元有效能效率由7.1%提高到16.0%;节流压力由6 MPa降至4 MPa,制冷单元有效能效率由19.6%提高至26.1%。分析认为,适当提高染色温度,降低节流压力,可以提高染色系统的有效能效率。In order to further promote the industrialization of supercritical CO 2 anhydrous dyeing system,the energy consumption was calculated by the available energy analysis method.The energy balance equations of each unit in the system were established,the unknown parameters of CO 2 were calculated through the PR equation,and the energy loss of the system was calculated by using the residual function method.The effects of dyeing temperature on the efficiency of the heating/dyeing unit and throttle pressure on the efficiency of refrigeration unit were investigated.The results show that the sum of the available energy loss in the heating/dyeing unit and the refrigeration unit accounts for more than 60%of the input available energy of the system,which is the key parts for the system energy saving.Moreover,the available energy efficiency of the heating/dyeing unit rises from 7.1%to 16.0%when the dyeing temperature is raised from 353.15 K to 393.15 K.The available energy efficiency of the refrigeration unit rises from 19.6%to 26.1%when the throttle pressure reduces from 6 MPa to 4 MPa.According to the analysis,the system available energy efficiency is improved effectively by raising the dyeing temperature and reducing the throttle pressure.
