为初步了解新型工质TFE-TEGDME用于吸收式制冷中的可行性,在同样的设计条件下,对采用该工质的制冷系统进行中压双效复叠循环与基本GAX循环分析,计算得到基本GAX循环有较高的COP值。但在温度较高(140℃)时,较小的放气范围导致基本GAX循环COP值较低,运行性能较差。 In order to understand the feasibility of using TFE-TEGDME as a new refrigerant in absorption refrigeration, under the same design conditions, the medium-pressure double-effect cascade cycle and the basic GAX cycle analysis of the refrigeration system using this working fluid were calculated. The basic GAX loop has a higher COP value. However, at higher temperatures (140 ° C), a smaller bleed area results in lower COP values ​​and poor runnability of the basic GAX cycle.
