Desiccants can be used in conjunction with solar energy to provide a viable alternative to traditional air conditioning techniques. Liquid desiccant regeneration was proved to be an effective method to extract the moisture from solution with a relatively less energy in order to regenerate the desiccant. An experimental study was carried out to analyze the effect of temperature for regeneration ...

Liquid desiccant systems have received significant attention as a way to reduce latent loads. Tests of liquid desiccant systems in humid climates have shown significant reductions in energy consumption. As moisture in the air is absorbed at the dehumidifier, the temperature of the liquid desiccant increases due to the addition of heat from the enthalpy of condensation of the water vapor. Thus, ...

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...

The objective of this project is to investigate an energy efficient air conditioner to be able to compete with conventional vapour compression systems. Liquid desiccant air dehumidifier/indirect evaporative cooling using cross-flow type Plate Heat Exchanger (PHE) as dehumidifier offers a cost effective and more environmentally friendly air conditioning system. It removes moisture form the air a...

A nominal 10.5-kW (3-ton) open-cycle liquid desiccant d ehumidification system has been design_ed, installed, and successfully operated at the Solar Energy Applications Laboratory, Colorado State Umvers1ty. Packed bed units were used to dry the air in the dehumidifier and to concentrate the desiccant _m the regenerator. Liquid distribution in the regenerator was studied for two systems: a gravi...

Combined Heat and Power (CHP) involves on-site or near-site generation of electricity by using gas-fired equipment along with utilization of waste thermal energy available from the power generation process and have the potential to achieve an overall system efficiency of 80% because of the utilization of thermal energy, that would otherwise be wasted, and the reduction of transmission, distribu...

An experimental investigation on the performance of a proposed hybrid desiccant based air conditioning system referred as HDBAC is introduced in this paper. HDBAC is mainly consisted of a liquid desiccant dehumidification unit integrated with a vapor compression system (VCS). The VCS unit has a cooling capacity of 5.27 kW and uses 134a as refrigerant. Calcium chloride (CaCl2) solution is used a...

Desiccant dehumidification has been given increasing interest in the air conditioning industry. Compared with conventional vapor compression air conditioning systems, desiccant dehumidification saves energy by separating humidity control from temperature control and also improves the indoor air quality as a good filter. This research explores the potential of applying desiccant dehumidification...

Optimization of the open absorption desiccant cooling system has been carried out in the present work. A finite difference method is used to simulate the combined heat and mass transfer processes that occur in the liquid desiccant regenerator which uses calcium chloride (CaCl2) solution as the working desiccant. The source of input heat is assumed to be the total radiation incident on a tilted ...
