转轮除湿器的数学模型及性能研究

Mathematic model and performance of desiccant wheels

建立了转轮除湿器的传热传质数学模型,利用有限差分法对方程组进行离散求解,并编制程序进行模拟,模拟结果与实验数据吻合较好,得到了稳态运行一个周期内空气温湿度和吸附剂温度、吸附率的变化规律及转轮除湿能力的影响因素。

Develops a numerical model of heat and mass transfer of rotary desiccant wheel, solves it by finite differential method and simulates it by self-programming. As a result, the numerical data accord well with those from experiments. Obtains the varying regularity of air temperature and humidity, adsorbent temperature and adsorption ratio. Presents the affecting factors on dehumidifying capacity.
