介绍了超临界流体跨临界循环与传统亚临界循环的不同特点 ,对跨临界循环的最优压力进行了理论分析和研究 ,对超临界流体的跨临界循环的最优压力影响因素进行了分析和比较 ,探讨了超临界流体跨临界循环在热泵和干燥领域的应用前景 .

The paper has made the contribution to the introduction of the characteristics of transcritical cycles that are different from the subcritical cycles. The main difference is that transcritical cycles have an optimum high pressure at which the coefficient of performance reaches maximum. The paper also investigates the influence factors of the optimum pressure and discusses the applications of transcritical cycles in heat pump and drying fields.
