    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...

    Metal foam – a material for heat engineering

    Metal foams are increasingly developing into materials with diverse uses. While metal foams with closed pores have already become established as rigid and strong lightweight materials, the open-cell variant is suitable for thermal engineering applications. Until now, the material has been rarely used in heat exchangers or coolers because the production is expensive and its application little tested. Researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden now want to change this.  more...
     

    Cooling with solar heat

    The cooling or air conditioning of buildings with solar heat has a particular appeal because the heat demand and supply are usually consistent with each another. Cold stores in southern climates and many process refrigeration systems also require considerable energy when the sun shines intensely. The use of solar cooling systems instead of electric chillers also eases the grid, particularly at peak load times.  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...
     

    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...
     

    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...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...
     

    Bee and bumblebee begin field tests

    As part of a joint project with Vattenfall and ZAE Bayern, scientists from the TU Berlin have developed two new absorption chillers. The 50-kW unit, which the researchers have nicknamed Bee, and the larger 160-kW unit called Bumblebee use heat at a low temperature level for generating cooling energy. The prototypes are smaller, lighter and more powerful than comparable systems on the market. A field test is now starting.  more...

    The supermarket of the future saves energy

    The energy savings division at the discount store Aldi Süd in Rastatt should in the future only need two-thirds of the primary energy usually required for refrigeration, heating, ventilation, air conditioning and lighting. A compressor pack with carbon dioxide as a coolant which has been developed in-house, and which is coupled to borehole heat exchangers, not only cools food, but also provides temperature control for indoor areas.  In the third year of operation, the amount of energy consumed is coming close to the ambitious target levels.  more...

    Energy-efficient finishing in mechanical engineering

    When producing machine components, the grinding stage is a production process with comparatively low energy efficiency. Up to 90% of the energy deployed is released as frictional heat. Large amounts of lubricants and coolants flood the workpieces and tools to cool them. The supply of coolants and their processing require enormous expenditure, including in terms of the energy. Researchers from industry and science have therefore jointly developed new processes that produce significant savings potential with minimum lubrication.  more...
