Title:
Abstract:	Die Speicherung von Energie ist in der Wärmeversorgung von Gebäuden ein lange bekanntes Prinzip zur Sicherstellung optimaler Effizienz und bei der Einbeziehung erneuerbarer Energie eine Notwendigkeit. Eine neue Form des Eisspeichers als erdvergrabenes Wasserreservoir ist in den letzten Jahren vermehrt zum Einsatz gekommen. Da in vielen Fällen Unklarheit über die möglichen Energieflüsse bei der Beladung und bei der Entladung herrschen, sollen hier die Wärmeübertragungsbedingungen des Entzugswärmeübertragers im Eispeicher und die Wärmegewinne aus dem Erdreich diskutiert werden. Heat transfer in ice storage and energy gains from the soil. Storage of energy is a well-established principle in the heat supply of buildings for ensuring optimal efficiency and a necessity for the inclusion of renewable energy. A new form of ice storage as a buried water reservoir has been increasingly used in recent years. Since in many cases there is uncertainty about the possible energy flows during loading and unloading, the heat transfer conditions of the withdrawal heat exchanger in the ice storage and the heat gains from the soil are to be discussed here.
