对除湿冷却系统的关键部件除湿转轮进行了数值模拟。通过与已有的实验数据和数值计算结果的比较，验证了数学模型的正确性。计算结果与实验结果和数值计算结果吻合较好。作为关键的操作/设计参数，已经在60°C至150°C的再生温度范围内检查了轮速和再生面积比。这些参数的优化进行的基础上，通过其除湿能力（MRC），这是更合适的比有效性作为一个性能指标的不平衡流的车轮性能进行评价。同时还考察了室外空气温度和湿度对最佳设计参数的影响。
Numerical simulation has been conducted for the desiccant wheel, which is the crucial component of a desiccant cooling system. The mathematical model has been validated by comparing with previous experimental data and numerical results. The calculation results are in reasonable agreement with both, experimental and numerical results. As the key operating/design parameters, the wheel speed and the area ratio of regeneration to dehumidification have been examined for a range of regeneration temperatures from 60°C to 150°C. Optimization of these parameters is conducted based on the wheel performance evaluated by means of its moisture removal capacity (MRC) which is more appropriate than effectiveness as a performance index of unbalanced flows. Also the effects of the outdoor air temperature and humidity on the optimum design parameters are examined.
