HYBUILD D3.3 - Full hybrid storage integrated

Deliverable D3.3 "Full hybrid storage integrated" describes the integration phase of the hybrid storages for the Mediterranean and the Continental concept in the laboratories. Special focus was put on the hydraulic and electric integration of the main components. With D3.3, the knowledge about the integration of the specific components of the HYBUILD concepts is passed to the demo sites inside the HYBUILD project, where the technologies will be installed. Furthermore, it may help researchers and developers working on future experiments with the same or similar components. Therefore, potential problems in the system integration can be identified in advance. Although the thermal and electric storages used in both concepts of HYBUILD are similar, their integration into the two concepts is different. Hence, both concepts are always dealt separately in the following. For the Mediterranean sub-system, the main purpose of the activity described in D3.3 was the integration of the different components: heat pump with latent storage (RPW-HEX), batteries with DC bus and sorption module and the subsequent integration of all of them together at lab scale. For the Continental sub-system, the main purposes were: the integration of the heat pump with a DC powered inverter and the latent storage (RPW-HEX) in a first experimental test series (2019) and the integration of the heat pump with a DC powered inverter, the latent storage (RPW-HEX), the decentralized DHW storages and the thermal controller in a second experimental test series (2020). The aim of the second test series was also to demonstrate heating/cooling and DHW-generation operation under realistic test conditions in the lab.
