A mathematical model for predicting the performance of a compound desiccant wheel (A model of compound desiccant wheel)

Applied Thermal Engineering, 2010
Abstract A mathematical model for predicting the performance of novel silica gel haloid compound desiccant wheel is established. Both the gas side resistance and the solid side resistance are considered in the model. It is found that the results of this model agree better to the experiments than the results of a former model which does not take the ...

Effect of desiccant isotherm on the performance of desiccant wheel

International Journal of Refrigeration, 2009
Abstract Numerical simulation has been conducted for the desiccant wheel, which is the crucial component of a desiccant cooling system. As the key operating/design parameters, the rotation speed and the area ratio of regeneration to dehumidification have been examined for a range of regeneration temperature from 50 °C to 150 °C. Optimization of these

Performances of the Hybrid Active Desiccant Wheel System with Type III Desiccant

open access: yesApplied Mechanics and Materials, 2010
A new type of hybrid desiccant air conditioning system combining an active desiccant wheel with a conventional front-positioned cooling coil is presented, in which Type Ⅲ desiccant is used in the active desiccant wheel. Then a preliminary experiment is carried out in order to investigate the feasibility of the hybrid desiccant system serving as a ...

Analytical modeling of a desiccant wheel

International Journal of Refrigeration, 2014
Abstract A simple integral model is presented for a desiccant wheel. The original governing equations for a desiccant wheel were simplified to a set of linear ordinary differential equations and an analytical solution was obtained. A brief analysis is given about the solution regarding the non-dimensional numbers that decide the behavior of a ...

Performance investigation of an internally cooled desiccant wheel

Applied Energy, 2018
Abstract Desiccant wheels are commonly used to dehumidify air in air-conditioning system to reduce the energy consumption. The objective of this study was to design, test and analyse the performance of a novel tube-shell, internally water-cooled desiccant wheel.

Comparative study of different desiccant wheel designs

open access: yesApplied Thermal Engineering, 2011
Desiccant/evaporative cooling systems offer an environmentally benign alternative to conventional vapour compression chillers. A desiccant wheel is the heart of this heat driven cooling system and it uses a solid desiccant for dehumidification with ...

Desiccant wheel regenerated by thermal energy from a microcogenerator: Experimental assessment of the performances

open access: yesApplied Energy, 2011
Hybrid desiccant HVAC systems have shown several advantages, compared to conventional cooling and dehumidification systems. Therefore, their use is also spreading for tertiary and residential buildings, especially when the regeneration of the desiccant ...
