Optimisation of heating and cooling networks

EnEff:Wärme promotes specific network optimisation with the aim of further increasing the share of local and district heating and integrating less densely populated areas into the supply network. This could be the future of central heat supply systems. District heating networks, so-called smart grids, are to become central building blocks in local energy management. Low-exergy technologies (LowEx) help reduce transmission losses. Furthermore, new adaptive cooling and heating networks offer starting points for the integration of renewable energy.

Simulation-based optimisation of energy efficient heating networks in Ludwigsburg

The research project includes the development of a simulation program and test rig for integrating decentralised, renewable heating sources. They will be used as part of an operationally based simulation of the heating network in Ludwigsburg-Sonnenberg for the purpose of automatically monitoring the operation and providing intelligent regulation.

Decentralised feed into local and district heating networks – using the example of solar thermal energy

The multifunctional use of district and local heating networks could already make a notable contribution to realising low-emission heat supplies in the short to medium term. For this purpose, the research project is investigating the technical and ecological effects of decentralised feed in using coupled simulations. The requirements for system components will then be defined and innovative technologies and system solutions developed.

Geothermal use of pit water for local heating supply

The pilot project for geothermal use of flood water from the excavation voids of the former Zwickau hard coal region is intended to demonstrate new concepts of efficient thermal heating supply and air conditioning.

Smart energy management – Intelligent energy management of electricity, gas, heating and cooling systems

As part of the project and in cooperation with industrial partners, an interdisciplinary research group from the TU Dresden is developing an active load and generation management system for decentralised systems in the urban environment. The focus is on developing and testing analysis tools.

Heat from pit water in Bochum-Werne

In Bochum-Werne, an innovative concept for generating environmentally friendly geothermal heat from pit water is being developed, tested and optimised for heating existing buildings. The utilisation of heat from pit water is therefore being promoted as a local contribution to achieving an economic and environmentally friendly energy mix.
