Welcome to ALDACS!

ALDACS — Advanced Liquid Desiccant -Based Air Conditioning Systems, combine Open Absorption with Indirect Evaporative Cooling, to achieve independent control of humidity and temperature of the supply air to air-conditioned spaces.

ALDACS pertain to a class of Air Conditioning Systems that require neither Chillers nor Cooling Towers. ALDACS are driven by Thermal Effluents at temperatures ranging from ~ 40 °C to ~ 80 °C, and require electric power to drive ventilators and small pumps only.

While conventional Liquid Desiccant-based Air Conditioning Systems, LDACS, contact air directly with Liquid Desiccant, ALDACS do this indirectly, solving, or avoiding, a wide range of issues of the LDACS approach, namely:

 — Poor wetting of the contacting surfaces, e.g. when using
   column packings, polymeric surfaces, etc.;

 — Air transport of corrosive,life threatning aerosols;

 — Loss of desiccant due to aerosol transport;

 — Contamination of the desiccant with particles, eventually
   with exogenous substances present in the air as well;

 —  . . .

The ALDACS Site

The ALDACS site is conceived to inform, form and support the spread of this Environment Friendly Technology.
Environment Friendly means the – Thermodynamically and Economically WISE – degradation of resources.
You'll find here scientific and technological information on the developments undertaken in the past ten (10) years of our work on liquid desiccant-based air conditioning systems.

Our main objective is to further the development of ALDACS worldwide, without the common IP constraints.

If you use our methods, propositions, ideas, and techniques, please acknowledge them.
Shall you need our Technical Support in your own developments, we are ready to provide it!
