| Abstract | The ATES Triplet can be a key technology in decarbonizing the heating and cooling of buildings, as it reduces the dependency on grid electricity whilst reducing the CO2 emissions. It does so by utilising on-site renewable energy generation and an Aquifer Thermal Energy Storage (ATES) system. This system relies solely on passive heating and cooling, requiring sufficient stored energy to be available when needed. Hence, the ATES has two energy supply wells (hot and cold), and a buffer well. The buffer well prevents thermal degradation of the hot and cold wells when return water flows from the building do not meet the required temperature for injection. The inherent variations and uncertainties in heating and/or cooling demands may cause the wells to run out of energy. As a result, peak loads may require too high flow rates, because the supply is limited by the maximum flow rate of the wells. Hence, timely detection of potential deviations from normal operation windows, to implement mitigation actions, is therefore key to ensure proper functioning of the ATES Triplet system. In this contribution we present the functioning of the Triplet under different climate conditions and evaluate the key points where the system may fail to supply the energy demand. The research aims to determine the indicators that need to be monitored and used for Fault Detection helping to ensure a stable system performance. |
