Optimization of desiccant element and energization control in energization-regeneration type desiccant air conditioning

The authors have proposed a new regenerating method for desiccant air conditioning system, “energization-regeneration,” where joule heating regenerates a dehumidifying element comprising conductive polymers with honeycomb core structure. The method controls positional-and-temporal partial heating regeneration for the element. This study first adjusted the element's conductive polymer compositions and configuration to improve dehumidifying performance; then, the input energy was controlled according to positions and time to improve energy efficiency, thereby clarifying the optimal conditions of the element and energization control. The results showed that this method is capable of presenting greater dehumidifying performance and energy efficiency than conventional regeneration methods.
