Abstract

It was found that there were still very limited studies for the dynamic operation and transient performance of the dehumidifier. Besides, the coupling study of heat, mass and flow was not comprehensive and lots of assumption was made to start the simulation. Lack of accurate prediction, the guidelines of control system design and operation cannot be put forward appropriately. Therefore, the paper established a reliable dynamic model for the dehumidifier. With the model, it obtained the transient response performance of the dehumidifier under changing boundary conditions, such as response time and response curves of outlet parameters. The magnitudes of the influences of various inlet parameters was analyzed, providing reliable and effective predication of the transient response performance of the dehumidifier.
