to reduce the primary energy consumption. The development of the composite adsorbents made possible a reduction of the charging temperature from > 120°C to 80°C. In addition, the optimized design of the overall process signiicantly increases the speciic power from 120 W / kg to 269 W / kg. Utilizing the cooling effect A further advantage of the system is the additional possibility of exploiting the cooling effect. When the hygroscopic zeolite binds water vapor in its pores (and heat is released in the process), heat is removed from the water tank by means of vaporization and can then be used for cooling purposes. Outlook In addition to the building technology applications for water heating, heating and cooling, due to the modular design the system can be adapted lexibly to other applications, for example industrial uses. For potential end users the new heat storage technology provides economic and process engineering advantages that result from an increase in energy eficiency and savings in energy costs. 1 Zeolite bed in the test reactor. 2 Modular storage unit for testing purposes. 2 Contact Dr.-Ing.
