Study on Mathematical Model of Desiccant Wheel
IOP Conference Series: Earth and Environmental Science, 2020 Abstract In the process of dehumidification and regeneration, a complicated heat and mass transfer process occurred between air and hygroscopic materials in desiccant wheel. The performance of dehumidifier is affected by the air inlet state parameters, regeneration air inlet state, air flow, regeneration air flow, and wheel speed and ...

Internally cooled desiccant wheel and desiccant wheel based air-conditioning system
, 2019 This thesis aims to improve the dehumidification performance of conventional desiccant wheels by constructing an internally cooled desiccant wheel, in which cooling water was brought into the supply section of the wheel to change the dehumidification process from adiabatic to an isothermal/semi-isothermal process.

Heat and Mass Transfer in Desiccant Wheels
, 2011 1.1 Background Nowadays the interest in heating, ventilation, air-conditioning and refrigerating systems (HVAC&R) based on desiccant wheels is increasing due to the possibility of using renewable energy sources, making them an attractive alternative or complement to conventional systems. The thermally driven desiccant systems can potentially reduce the

Effect of Regenaration Air Temperature on Desiccant Wheel Performance
International Journal of Technology, 2016 Desiccant wheels are used as an air dehumidifier in air-conditioning and industrial applications. Desiccant wheel performance determines the size and cost of the whole system. A good desiccant wheel is one that saves energy usage. This article presents an experimental investigation on the effects of varying the regeneration air temperature, viz., 50 ...
