001005142 520__ $$aTo decarbonize the building sector, using waste heat sources in district heating systems is crucial for the futureefficient and sustainable heat supply of buildings. This paper investigates a possible integration of a large wasteheat source into an existing local district heating system on the research centre campus in J¨ ulich, Germany.The new energy source to be integrated into the district heating system is a new high-performance computerthat supplies waste heat at a low-temperature level. We investigate the possibilities of integrating the wasteheat source based on the design of the currently operating combined cooling, heating and power generationsystem by calculating and evaluating different system concepts. In addition, we prove the feasible waste heatintegration into the district heating system through network simulations in Modelica. The environmental benefitsin terms of carbon dioxide reduction are evaluated while showing the challenges for an economic realization.However, the usable waste heat in the current energy system is limited since a high workload operation ofthe present combined heating and power system is necessary for an economical operation. Therefore, westudy an approach to maintain a high workload of the combined heat and power system by shifting a higherproportion of high-temperature heat to the absorption refrigerator for cooling purposes. The studied options ofwaste heat integration into the local district heating system show a reduction of carbon dioxide emissions upto 3,396 tCO2 per year. Furthermore, economic integration of the new waste heat source is also feasible byimplementing the studied measures in the local energy system. Therefore, this study shows that it is possibleto integrate a low-grade heat source into an energy system that is mainly supplied by a combined cooling,heating and power generation system.
