| 摘要: |
| 对并联型调温除湿系统停机现象进行了分析，指出双冷凝器压力不平衡是产生制冷剂积存、压力波动导致停机的原因。在此探讨了几种改进策略，指出了各方法的优缺点。提出了在由调温除湿向冷冻除湿模式转换时将再热冷凝器作为蒸发器的双蒸发器模式设想，并搭建了实验台，进行了相关实验研究，结果表明：该模式可解决制冷剂积存而导致停机的问题，可实现不同运行模式的转换，制冷除湿效果优于单蒸发器模式的效果。 |

| Abstract: |
| The shutdown reason of parallel condensers dehumidifier was analyzed. It is shown that the unbalance of the pressure in the two condensers is the main reason for shutdown, which leads to the accumulation of refrigerant and fluctuations of pressure.The advantages and shortcomings of several methods to improve the performance were discussed. The reheat condenser is proposed to be changed to evaporator when the mode turns to freezing dehumidifier. Test bench was set up and experiment was carried out.The result shows that the mode could resolve the shutdown incident. Moreover, the EER and dehumidification capacity of double evaporator mode are better than the traditional dehumidifier with one evaporator. |
