| 摘要: |
| 提出一种内热再生式固体除湿器，描述了其物理模型和工作中传热传质过程的数学模型，并编写了基于有限差分法的数值求解程序对其控制方程组进行求解。通过搭建实验台进行实验，测得了除湿器在除湿再生过程中的动态特性，并与模拟结果进行了对比分析。模拟和实验结果均表明，除湿器在不采用内冷措施的情况下对夏季室内的高湿气体或微环境内的低湿气体均具有较高的除湿效率，再生时间远小于有效除湿时间，吸附床床体压降小，对室内小型空间的除湿需求具有很好的适用性。 |

| Abstract: |
| An internally-heating regenerated dehumidifier is proposed, its physical model and mathematical model for heat and mass transfer process are described, and a numerical procedure based on finite difference method is developed to solve the governing equations. By conducting experiment researches, the dehumidifier’s dynamic behavior is measured, and then compared with simulation data. Result shows that the dehumidifier has a high dehumidification efficiency for both indoor air with high moisture content in summer and relatively dry air in microenvironment without inner-cooling device, the time consumed in regeneration and cooling process is much less than that consumed in dehumidification process, and the pressure drop in fix bed is small, which indicates that the dehumidifier can be widely used in dehumidification for small indoor space. |
