Performance Enhancement of Rotary Desiccant Wheel using Novel Homogenous Composite Desiccant Designs
IOP Conference Series: Materials Science and Engineering, 2021 Abstract Rotary solid desiccant wheels are used as sensible and latent heat recovery wheels in the Desiccant-HVAC systems. The two major types of these wheels include enthalpy (total energy recovery) wheels which remove sensible heat and latent heat from process air and transfer them to regeneration air, and dehumidification wheels which
