OPEN ABSORPTION SYSTEMS FOR AIR CONDITIONING AND THERMAL ENERGY STORAGE

Abstract

Open absorption systems for thermal energy storage have been investigated over the last years. Open sorption systems using liquid desiccants like Lithium chloride are able to dehumidify an air stream. By adiabatic humidification this dry air can be cooled down and used for air conditioning of buildings. These systems provide cool and dry air to the rooms. At the same time these systems are able to store thermal energy very efficiently. The thermal energy can be stored within the difference of salt concentration between the diluted solution (after absorption) and the concentrated solution (after regeneration).Examples of demonstration projects will be given.Asolar application for the dehumidification of an office building and an application connected to a district heating net for the cooling of a jazz club will be presented in detail.
