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...

Fuel cell generates electricity and heat for homes

Highly efficient, low-emission and quiet: as small-scale combined-heat-and-power stations, new fuel cell heating units produce heat energy and electrical energy with an efficiency of over 90 per cent. They have proven themselves in extensive tests in single and two-family homes, and their operation and design have been improved incrementally. The first units are now on the market. They run on natural gas, and on hydrogen and methane produced using renewable energy or biomass. Decentralised fuel cells can generate demand-oriented electricity, and they can be used in a grid-friendly or grid-independent way.  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...

Efficiently heating & cooling non-residential buildings

The use of environmental energy to cool or, in combination with heat pumps, to heat non-residential buildings via thermo-active building systems (TABS) has established itself in recent years. The objective of such building and system concepts is not only to consume as little energy as possible in quantitative terms (low energy), but also to achieve the most optimal energy conversion in thermodynamic terms that takes the quality of the energy used into account (low exergy, „LowEx“).  more...

Schools plug into the sun

Photovoltaic systems in schools help save energy and enhance classroom teaching. They shape a school's image and indicate that energy supply is a future-focused subject. Grants are available to schools wanting to install photovoltaic panels.  more...

Schoolchildren are saving energy

At many schools they already exist: schoolchildren as energy detectives, energy managers or energy teams. They track down energy leaks, take the initiative, assume responsibility and ultimately know a great deal about saving energy. Their commitment is often also financially rewarding for their school.  more...
