Characterization of desiccant wheels with alternative materials at low regeneration temperatures

Experimental analysis and numerical modelling of an AQSOA zeolite desiccant wheel

“…Further details about the facility can be found in White et al [21]. Experimental results are provided in Section 4.…”

“…If face velocities are kept constant, increasing AR leads to an increase in process air flow rate but, on the other hand, a reduction in humidity ratio drop. Overall desiccant wheel performance is commonly described by the Moisture Removal Capacity (MRC), which is an indicator to assess the latent cooling provided [1,21,29]. The effect on maximum MRC achievable (Eq.…”

“…Dawoud [19] provided an insight into water vapour adsorption kinetics on small AQSOA-Z02-coated aluminium substrates for adsorption heat exchangers. Plenty of experimental results are available on alternative desiccant materials [20], however only few authors dealt with new generation of zeolites [21,22] and neither a comprehensive nor a model driven numerical analysis has been carried out on AQSOA zeolite-based desiccant wheels.…”

Heat and mass transfer of composite desiccants for energy efficient air dehumidification: Modelling and experiment

“…However, the transport phenomena involved in such a processing technology is complicated. In a recent paper, it was found that dehumidification achieved by a zeolite desiccant wheel is generally less than that achieved by the silica gel desiccant wheel [1]. It was observed that the polymer desiccant shows much larger sorption capacity than silica gel at most relative humidity.…”

“…It was observed that the polymer desiccant shows much larger sorption capacity than silica gel at most relative humidity. Furthermore, it was shown that the polymer desiccant has a higher regeneration rate than silica gel [1].…”
