Mathematic model and performance of desiccant wheels

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.
