Practical Test on a Closed Sorption Thermochemical Storage System with Solar Thermal Energy

This paper presents the actual status of the experiments done with a large scale adsorption thermochemical storage system of a 750 liter volume in combination with solar thermal heat pipes as well as recent results of cyclic tests done on the used storage material. An output temperature of maximum 120 °C was realized to charge the storage system at a maximum of 4 kW thermal capacities. Through the succeeding discharging process, adequate thermal energy with temperatures above 60 °C could be released for providing hot water and space heating of an energy-autarkic house.
