The goal of the DEHUMID project is to develop and test a low cost, compact, and energy efficient liquid desiccant dehumidification system that can precondition the outdoor air delivered to buildings and homes to save energy by reducing compressor size and eliminating excess chiller capacity. As an added benefit, the system will also improve indoor air quality and comfort by removing excess humidity, thus reducing the growth of mould and mildew that create 'sick buildings' and destroy valuable property.

To achieve satisfactory results with respect to the identified objectives a three-stage RTD project is anticipated. During Stage 1, research is being conducted to define the functional specifications, as well as to identify how best to improve both (1) the lithium chloride delivery and recovery system, as well as (2) the best formulation for the lithium chloride desiccant solution. Especially creating large (wetted) exchange surfaces with the very small specific solution flow provide a big technical challenge because of the problem of carrying over LiCl to the airstream.

The technical route to overcome this is applying the ufalling film principle. To achieve maximum benefit from the desiccant dehumidification system and for proper sizing, understanding the variables that affect the performance is essential.For this reason the system will be modelled and a small-scale test bed will be designed to test system principles and verify system parameters. In Stage 2 the system and their components will be designed, including the mechanical liquid desiccant delivery and recovery prototype system and a PC-based control system (including environmental sensors) to provide the interface for customized process control. The system components will be integrated into a working prototype. In Stage 3 the system will be validated and tested, both in laboratory testsand in real-world applications under field conditions (environmental conditions, user-friendliness).
