Regenerator type storage systems using extended heat transfer surface represent the state-ofthe-art in latent heat storage. These systems show a decreasing heat flux while discharging due to the coupling of heat exchanger and storage material. The PCMflux concept aims to overcome this disadvantage by the separation of power and capacity. Here, the storage material is filled into open containers made of aluminium that are moved over a heat exchanger. This offers the possibility to control the heat flux of the storage system while discharging by adjusting the velocity of the containers. The theoretical examination of this concept is finished and an experimental proof-of-concept was constructed. Within this paper, the PCMflux concept is briefly outlined and the experimental setup is described. First experimental results show both the feasibility of the PCMflux concept and the good agreement between theory and practice.
