    Exhaust heat cools lorry cab

    Time for a break! The driver stops his lorry at the truck stop. To ensure that the cabin also remains cool even in summer, the engine also continues idling when the lorry is parked, often for hours. This produces noise and wastes fuel. However, researchers at the University of Stuttgart have now demonstrated that pleasant temperatures can still be reached even when the engine is switched off and there are no additional energy inputs. They have developed a special adsorption chiller. This utilises the exhaust heat produced while driving for air-conditioning the parked vehicle.  more...

    Pilot production of thermoelectric modules

    Thermoelectric generators convert waste heat directly into electricity. They utilise temperature differences and are paving the way for more energy-efficient production processes. However, the technology has previously led a niche existence because the module production is labour-intensive and therefore expensive. Researchers from Freiburg now want to improve this.  more...
     

    Ceramic cube reduces gas losses

    Scientists have developed a new ceramic heat exchanger for industrial furnaces. This can transmit considerably more exhaust heat to the combustion media than the metal recuperators currently used in high-temperature furnaces in the process industry. The new ceramic recuperator thereby decreases the exhaust gas losses to less than 25 per cent.  more...
     

    TU Darmstadt opens research factory

    Last week, the ETA model factory officially opened its doors. Here, scientists at the Technical University (TU) Darmstadt are researching under real conditions and at full scale how industry can use energy more efficiently by linking all building and production components. By considering the entire system – consisting of machines, energy storage systems, building technology and the building envelope – the intention is to reduce the primary energy requirement in production by 40 per cent.  more...

    Thermoelectrics: power from waste heat

    Waste heat is produced in all areas of daily life – in industry, homes and transport. In Germany alone, this adds up to a waste heat potential of 300 TWh per year. This energy volume corresponds to nearly half the total energy consumed by German industry. Thermoelectric generators (TEGs) can tap into this huge energy reservoir and transform the "waste energy" without moving parts into a higher form of energy.  more...
     

    Neckarpark Stuttgart: Heat from waste water

    Sewage stinks and is filthy – but it is suitable for supplying heating and cooling to buildings. In Stuttgart’s new Neckarpark urban district, the energy in the municipal waste water is extracted by means of a trough heat exchanger in the sewage channel and utilised via a low-temperature local heating network. This provides the basis of the energy concept for the new district, which is being created with highly energy-efficient buildings on the brownfield site belonging to the former Bad Cannstatt railway freight depot.  more...

    Thermal storage systems brought into shape

    Thermal storage systems that utilise zeolite are still very rare. In a research project, scientists have investigated aluminosilicates for their practical use in thermal storage systems. They have succeeded in significantly improving the energy density, cycle resistance and thermal performance. The research has led to the development of a thermochemical storage system for a CHP power plant.  more...
     

    Energy diet for confectionary manufacturer

    The confectionary manufacturer, Ferrero, and the packaging specialist, Junghans, want to save half the energy that they previously required for production. With the help of a new energy monitoring system, they also want to become smart consumers: They would then purchase energy, when it is cheapest for them. A recently started research project will define what the companies have to change in terms of production and management.  more...
     

    Saving energy in commercial and industrial parks

    Industrial parks are typically home to a diverse mix of cross-industry businesses. The requirements of these businesses vary when it comes to energy supply depending on the nature of their production. For businesses in the metal processing industry for instance, thermal energy requirements in the range of many hundreds of degrees Celsius are typical, while in the food industry, heat requirements are rarely above a hundred degrees Celsius. Businesses operating in the direct vicinity can make good use of waste heat from such processes.  more...
     

    Start signal for model factory

    Mechanical engineers, construction engineers, architects and industry experts have developed a new production facility: the so-called ETA factory. The foundation stone was laid for it on 12 August 2014. This initiates the start of construction of the model factory at the Technische Universität Darmstadt, in which in future machines, building technology and the building envelope can be energetically linked and perfected. It is scheduled to open in October 2015.  more...
