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 ...

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...
