Description

Angular distributions of air humidity and temperature developed at each outlet of a desiccant rotor,which was operated under the low dew point air production condition / process configuration, were carefully measured and discussed for the help in construction of mathematical model of the desiccant rotor and verification of the simulation results in a series of our study. Measurement of the angular distributions was carried out varying the rotation speed of the rotor, regeneration air temperature and process inlet air absolute humidity. Also, humidity chart was employed to interpret the angular distribution or the change of air condition along the rotation angle. It was found that the change of dehumidification and regeneration outlet air condition along the rotation angle had almost the same feature found in the desiccant rotor used for general air-conditioning. This suggests that the conventional computational model can be essentially applied to the simulation in low dew point air production condition, except that the magnitude of adsorption heat and its dependency on the amount of adsorbed water should be correctly measured and applied to the calculation.
