| 目前复合冷凝技术已经形成了行业标准,替代制冷剂在复合冷凝系统中的应用特性研究是一种趋势。有限时间热力学方法和分析方法和SIMULINK软件被引入建立氟系替代制冷剂R407C和R410A在复合冷凝系统的仿真模型,其对象为风冷热泵复合冷凝过程。氟系替代制冷剂R407C和R410A在复合冷凝系统中的热力学特性被模拟,并与原R22系统的性能做了对比。结果表明:R410A复合冷凝系统卫生热水水温上升速度比R22系统快,20 min时上升到约60 ℃,而R407C复合冷凝系统卫生热水上升速度比R22复合冷凝系统慢,约需50 min水温达到47 ℃左右。系统效率随用户要求的卫生热水水温温度升高而降低。R410A复合冷凝系统比R22复合冷凝系统略高3%~5%,而R407C复合冷凝系统比R22复合冷凝系统略低。 |

| Nowadays,the compound condensation process (CCP) has became the industry standard.The finite time thermodynamics and exergy analysis method and the MATLAB/SIMULINK software are employed to establish the CCP simulation model,with the fluorine substitute refrigerant R407C/R410A.The thermodynamic characteristic of the CCP systems are studied:the subject is an air-cooled heat pump unit.And it is compared with the R22CCP system.The result shows that:the increase speed of the sanitary hot water temperature with R410A CCP system is faster than the R22 CCP system,it needs about 20 min to reach 60 ℃ that the users demand;and the R407C CCP system takes about 50 min to reach 47℃.The exergy efficiency declines according to the increase of the outlet temperature of the sanitary hot water.The R410A CCP system is about 3%～5% higher than the R22CCP system,and the R407C CCP system is a little lower than the R22 CCP system.The simulation method provides a theoretical reference for developing the production of CCP with fluorine substitute refrigerants R407C/R410A. |
