Abstract: A solar heating system was installed at “Ackermannbogen” in Munich, where a residential area was built in 2007. To achieve a solar fraction larger than 50%, a large seasonal storage was installed to store solar surplus during summer and supply solar thermal heat in winter. To decrease the needed volume of this storage an absorption heat pump was installed into the system. This heat pump utilises heat from the storage and is driven by heat from a district heating grid. The low temperature heat is lifted to temperatures useable within the local heating grid to provide heat and domestic hot water to the residential area. Due to the demand on temperature levels of the system a “twin” absorption heat pump - consisting of two separate absorption heat pumps within a single shell - had to be installed for this application. In order to gain maximum benefit of the stored solar thermal energy the system controls change the mode of operation depending on the temperatures of the storage and the return temperature of the solar thermal collectors. The system was monitored and the collected data (capacities and temperatures of the absorption heat pump) of a representative day is shown in this paper.
