Heating, cooling and heat storage in open sorption systems for residential use

摘要

A simple method was developed to characterize solid adsorbents concerning their applicability in open sorption systems for the heating, cooling and heat storage in buildings. An appropriate adsorbent has to reach the temperature limit given by the heating/cooling system of the building. It has to provide a high energetic efficiency and a high energy density for storage applications. The criteria for the characterization can be calculated from the adsorption equilibrium of water vapor and the adsorbent as basic experimental data. An adsorption heat pump and a thermal energy storage (TES) have been installed. Experimental data of these systems were compared to the theoretically calculated values.
