Experimental Analysis of Air Dehumidification System With Liquid Desiccant
2010 14th International Heat Transfer Conference, Volume 8, 2010The performance of an air dehumidification system with lithium chloride solution used as a desiccant was studied experimentally. First, the mass-transfer coefficients were measured for a structured packed dehumidifier/regenerator. It was shown that the overall mass-transfer coefficients varied from 2.5 to 7.8 g/(m2·s) when the air velocity was ...

Liquid Desiccant Dehumidification Using Solar Regenerated System
2020The energy demand application to thermal comfort is increasing spontaneously in the world. Low-grade energies are promising potential to alleviate fossil fuels use. In the present system, 40% by mass solution of calcium chloride (CaCl2) absorb moist air directly from the process air to reduce the moisture before supply to indoor.

Dynamic behaviour simulation of a liquid desiccant dehumidification system
Energy, 2018Abstract Among heat driven air conditioning systems, liquid desiccant air conditioning system can be assisted by low water temperature solar collectors. This can reduce the electricity demand of the air conditioning systems. Furthermore, these systems can provide possibility of energy storage in the form of chemical energy in the liquid desiccant ...

A characteristic study of liquid desiccant dehumidification/regeneration processes
Solar Energy, 2005This article presents a research study on the process analysis of adiabatic liquid desiccant dehumidification/regeneration with slug flow assumptions. A controlling equation is developed for the quasi-equilibrium processes where the two fluid streams are in contact in quasi-equilibrium conditions.

A simplified model for air dehumidification with liquid desiccant
Solar Energy, 2004This paper describes a relatively simple model for the preliminary design of an air dehumidification process occurring in a packed bed using liquid desiccant through dimensionless vapor pressure and temperature difference ratios. An expression is derived using the aforementioned ratios to predict the water condensation rate from the air to the ...
