The desiccant material is a material which has ability to remove moisture from air. According to the physical and chemical properties, there are two types of desiccant material namely solid desiccant material and liquid desiccant material. In this experimental study, solid desiccant material is used. Solid desiccant material adsorbs moisture from air due to water vapour pressure difference. Som...

Recently, there have been many studies on dehumidifiers with a low flow rate of liquid desiccant, in which a plate-type heat exchanger with internal cooling is adopted. If the low flow rate of a liquid desiccant maintains a thin liquid film on the heat exchanger surface, heat and mass transfer performance would improve, the stability of the liquid film would increase, and there would be no entr...

Heat and mass transfer between air and falling desiccant film is investigated for inclined parallel and counter flow configurations. Two different configurations are proposed and parametrically analyzed. Effect of inclination angle is examined to study enhancements in dehumidification and cooling processes of the air and regeneration of liquid desiccant in terms of pertinent parameters. Cu-ultr...

This study discusses the choice of dehumidification systems for high-moisture indoor environments, such as swimming pools, supported by an eco-energetic performance comparison. Initially, causes high relative humidity and condensation in these spaces are reported, well available technologies. Two different solutions described: desiccant wheel re-cooling. The energy demand required a refrigerati...

Abstract For its efficient application of low-grade energy, the circulating wheel dehumidification air conditioning system has received a lot attention and research in response to shared challenges environmental protection, energy conservation, low carbon. Desiccant systems can recycle waste heat as desiccant regeneration source improve quality, which is expected achieve consumption high-effici...

The dehumidifier is a key component in liquid desiccant air-conditioning systems. Analytical solutions have more advantages than numerical solutions in studying the dehumidifier performance parameters. This paper presents the performance results of exit parameters from an analytical model of an adiabatic cross-flow liquid desiccant air dehumidifier. Calcium chloride is used as desiccant materia...

The use of air conditioning in buildings to provide a comfortable environment accounts for up 75% the electricity consumed Kuwait hot season from April through end October. widespread adoption systems has resulted an increased demand electricity. This led peak load that larger carbon footprint and placed grid under significant strain. Heat-driven solar energy are now emerging as alternatives el...
