Desiccant wheels are widely used in buildings to control humidity and reduce energy consumption. A model is presented based on transient coupled heat and mass transfer, to model, design and analyze the effects of geometrical characteristics of a honeycombed rotary desiccant wheel and its performance. Governing equations are solved numerically using finite volume method and the model is validate...

This article applies nonlinear programming techniques to optimize humidification-dehumidification (HD) desalination cycles for operating conditions that result in maximum gained output ratio (GOR). Closed air open water as well as open air open water cycles, each with either an air or a water heater, were considered in this analysis. Numerical optimization resulted in a substantial increase in ...

Humidification-dehumidification desalination (HDD) systems offer a feasible approach for the production of fresh water in inaccessible areas as they can be operational using renewable energy and require little maintenance. Various studies are being carried out to boost system performance. In this paper, an open air HDD is proposed that exploits enhanced evaporation condensation processes by imp...

The dispersion stability and the thermophysical properties of microencapsulated phase change material slurry (MPCMS) for liquid desiccant dehumidification were investigated experimentally. results show that, MPCMS can be improved greatly by adding surfactant. maximum absorbency with polyoxyethylene sorbitan monooleate (Tween80) is 4.1 times that cetyltrimethyl ammonium bromide (CTAB). monolayer...

Maintaining mechanical ventilation has been identified as a potential strategy for reducing the risk of virus infections. However, in hot and humid climatic conditions, delivering fresh air to building comes at an energy cost could impact occupant comfort due persistent need simultaneous cooling dehumidification. In this paper, performance novel hybrid conditioning system that handles is studie...

This work proposes a new device for air treatment with dehumidification and water recovery/storage, possible mitigation of indoor environmental conditions. The system is based on Peltier cells coupled horizontal earth-to-air heat exchanger, it proposed as an easy-to-implement alternative to the pumps handling units currently used market, in terms cost, ease installation, maintenance. process pr...

This work is motivated by the difficulty of cultivating crops in horticulture greenhouses under hot and arid climate conditions. The main challenge to provide a suitable greenhouse indoor environment, with sufficiently low costs environmental impacts. control inside constitutes an efficient methodology for maintaining satisfactory environment that fulfills requirements high-yield reduced energy...
