Abstract:
Our energy system is undergoing major changes. In order to mitigate climate change and reach sustainability, we need to use energy more efficiently and switch from fossil to renewable resources. In this work, the example of open heat distribution systems shows that considerable savings potential is possible through intelligent networking. The methodology combines quasi-dynamic simulation of mass and energy balances with exergy analysis. As a basis for this, the main thermodynamic statements provide information on the limitations of energy conversion as well as process-related exergy losses. Both in the municipal and in the industrial heat supply sector, projects are presented, which have the potential for lighthouse technology. On the basis of simulations carried out as well as tests in the real test network. In the real test network improvements in the low load and peak load segment can be achieved. The factors that determine efficiency in the district heating network have been worked out, as were proposals to optimize existing structures in the field of heat supply (pump cluster design). As examples of industrial heat production, two projects in the meat-processing and meat-processing industries are presented. Thanks to the redesign of an integrated heating and cooling system, it was possible to achieve a factor of 5 in the area of natural gas consumption (reduction by 81%), crediting Ernst Ulrich von Weizsäcker's proposals. In the same way, a reduction of 79% of greenhouse gas emissions could be achieved by improving the existing structures at the St. Martin site by implementing an efficient waste management and energy management system. The factor of 5 could also be achieved by this second example. In summary, it can be said that with the help of efficient heat distribution systems - both public and industrial - optimal exploitation of local resources can be carried out.
