摘　　要：在能量梯级利用的基础上,建立了双温热驱动跨临界CO_2-[emim][Tf_2N]吸收制冷系统,针对该系统的特点构建了相应数学模型,分析了各关键参数对系统性能的影响.结果表明,在一定条件下,与使用相同工质对的传统吸收制冷循环相比,本工作提出的系统性能系数(COP)最高增加50%.A transcritical CO2-[emim][Tf2N] absorption refrigeration system driven by double low-grade energy was built based on the principle of energy cascade utilization. In allusion to the characteristics of proposed system, the corresponding mathematical model was constructed. The influence regulation of key parameters to system performance was analyzed. The results showed that under given conditions compared with traditional absorption refrigeration system using the same refrigeration working pairs, the highest coefficient of performance （COP） of proposed system could be increased by 50%.
