METHOD FOR OPERATING AN ARRANGEMENT FOR STORING THERMAL ENERGY

摘要

The invention relates to a method for operating an arrangement (1) for storing thermal energy. The arrangement (1) comprises an energy storage (2) having a temperature gradient. The method comprises retrieving energy of a first temperature (T1) from the energy storage (2) for use in a first heat- absorbing system (3), such that free space is created in the energy storage (2) for energy of a second temperature (T2). The second temperature (T2) is higher than the first temperature (T1).
