Performance Enhancement of Rotary Desiccant Wheel by Innovative Designs of Multiple Desiccant Layers
2016Rotary Desiccant wheel in the desiccant air conditioning system is used for the dehumidification of process air by adsorption of water vapour by the desiccant (porous media) layer. And while the hot air which is heated up by the heater (or waste heat recovered from other equipments) flows through regeneration side, water is desorbed out from the ...

A desiccant cooling model is developed and applied to the ventilation, recirculation, makeup, and mix modes of the operating system. The mathematical model is based on the transient coupled heat and mass transfer and is used to predict the performance of the system under various design and operational conditions.

Analysis of Entropy Generation Mechanisms in a Desiccant Wheel
This work presents a novel detailed analysis of entropy generation mechanisms in a desiccant wheel (DW) by the the direct method, enabling differentiation of entropy sources by type and location. A detailed model of the desiccant-based system, implemented in Modelica, is used to compute entropy generation from various phenomena.Segura Schreiber, Jan +2 more

Experimental Investigation of Composite Desiccant Wheel Dehumidifier
Applied Mechanics and Materials, 2015Desiccant wheel dehumidifier is filled with solid desiccants, looks like a honeycomb structure which is open on both ends. Air is allowed to pass through the honeycomb passages, giving moisture to the solid desiccant contained in the wheel. The wheel constantly rotates through two separate air streams.

Theoretical analysis of dehumidification process in a desiccant wheel
Heat and Mass Transfer, 2005A mathematical model based on the one-dimensional Navier–Stokes equation is described. The current model is capable of predicting the transient and steady-state transport in a desiccant wheel. It reveals the moisture and temperature in both the airflow channels and the sorbent felt, in detail, as a function of time.
