由杨亮、李慧、蔡思维、邵亮亮、张春路（通讯作者）撰写的论文Minimizing COP loss from optimal high pressure correlation for transcritical CO2 cycle在Applied Thermal Engineering, 2015年第89卷在线发表。论文指出了二氧化碳跨临界循环最优高压控制方程研究中的一个常见疏忽，该疏忽导致循环COP在近临界点附近降幅达71%。针对此问题，作者提出了基于COP损失最小原则优化高压控制方程的新方法，使得COP最大降幅减至0.7%。本研究对于保证二氧化碳跨临界制冷/热泵系统的运行能效具体重要意义。

论文摘要：CO2 transcritical cycle has been successful applied in many refrigeration and heat pump systems. High pressure optimization and control play a critical role in maximizing COP (coefficient of performance) of CO2 transcritical systems. This work reviewed optimal high pressure correlations of transcritical CO2 cycles in open literature and found a potential significant COP loss near the critical pressure due to error propagation from optimal high pressure approximation to actual COP. Therefore, a COP loss minimization method is proposed to restrain the error propagation and obtain more robust high pressure correlation. Case study on the single-stage CO2 transcritical cycle demonstrated that the maximum COP loss from the conventional high pressure optimization method can be significantly reduced from ?71% to ?0.7% using the new method.
