Development of a thermal storage system based on the heat of adsorption of water in hygroscopic materials
conference paper
A thermal storage system based on the heat of adsorption of water in hygroscopic materials has been studied as a component of a solar space heating system. The aim of this project is to decrease the storage volume in comparison with a rock-bed storage system by increasing the stored energy density.
The measured stored energy density for several adsorbents are given. Further some system modifications are discussed with regard to a solar space heating system using a rock-bed storage system. The solar contribution of the system with an adsorbent bed, which has been calculated with our TPD computer simulation programme of a solar heating system, is given for the several adsorbents and has been compared with the solar contribution of the same system having a rock-bed storage system.
The project is carried out in the frame work of both the European and the Dutch Solar Energy Program and in co-operation with a Dutch firm.
