Kurzbeschreibung (Abstract)

The increasing expansion of renewable energies and the shortage of fossil fuels lead to rising and increasingly fluctuating energy prices. To benefit from these significant fluctuations and to become less dependent on fossil energy sources, this paper shows how the electricity demand of cooling supply systems for industrial room air conditioning can be flexibly adapted to the volatile energy supply. For this purpose, an energy-flexible air-conditioned climate room with a smart chiller and thermal storage units was built as a demonstrator at the ETA research factory at the Technical University of Darmstadt. To determine the energy flexibilization potential and to develop flexible operating strategies, a thermal simulation model of the climate room was also created in the simulation environment Dymola and experimentally validated. In addition, an energy-flexible operation of the climate room was validated on the real system and the economic potential was determined as well as the impact on sustainability was derived. The demonstrator shows that in the application scenario of air conditioning of cold storage facilities 26.3 % of electricity costs and 20.6 % of CO2 emissions can be saved by the developed energy-flexible operating strategies. The findings can be transferred and scaled to different cooling supply systems for industrial air conditioning.
