为研究除湿转轮的除湿性能,对其一个微通道建立二维、双扩散模型,模拟计算处理空气和再生空气入口参数对处理空气出口温度和含湿量的影响,得到各入口参数对出口空气温度和含湿量的影响曲线。结果表明:出口空气温度随着处理空气入口温度和相对湿度、再生空气入口温度和再生风量的提高而增大:出口空气含湿量随着再生风量、再生空气入口温度的提高而减小。将模拟结果与实验结果进行比较,发现二者趋势相同,温度的最大误差为7.5%,含湿量的最大误差为11.1%。这为除湿转轮的优化运行提供了参考。
In order to study the dehumidification performance of the dehumidification rotor, a two-dimensional and double-diffusion model was established for one microchannel to simulate the influence of inlet and regeneration air inlet parameters on the outlet air temperature and moisture content of the treated air. Temperature and moisture content of the curve. The results show that the outlet air temperature increases with the temperature and relative humidity of inlet air, inlet temperature of regeneration air and regeneration air volume. The outlet air moisture content decreases with the increase of regeneration air inlet temperature and regeneration air inlet temperature. The simulation results and experimental results were compared and found the same trend between the two, the maximum temperature error of 7.5%, the maximum moisture content of 11.1% error. This provides a reference for the optimal operation of desiccant wheel.
