The Institute for Thermodynamics and Thermal Engineering (ITW) of the University of Stuttgart has developed a novel solar powered 10 kW absorption chiller. This chiller was implemented in the cooling system of the institute's building. To achieve a higher efficiency of the cooling system and to extend the hours of operation, a small ice store was designed, constructed and experimentally investigated. The experimental investigations include charging and discharging processes at different inlet temperatures and for different heat exchanger areas. For theoretical investigations a simulation program was developed and validated. Based on the results of these investigations a final heat exchanger design was established. In a further step the ice store was integrated into the building's cooling system. Long term measurements of the cooling system have shown good in-service behaviour of the ice store which fits the specific requirements of the cooling system in combination with the absorption chiller quite well.
