Application of the Stirling cycle for environmentally compatible cooling - systems analysis
Conventional cooling has adverse effects on environment (eg. ozone depletion, global warming). One option for environmentally compatible cooling systems for near ambient temperatures (-10 to -50°C) is the Stirling cooler with environmental friendly process.
Instationarity as a limiting factor for the use of industrial waste heat in heating-networks
Industrial waste heat is predominantly instationary. Thus utilisation of industrial waste heat in district heating systems is constrained. A database and an evaluation methodology were developed to support increased utilisation of this heat source.
Ecologically friendly resin impregnation of rotating machines with the use of the joule effect
Windings of rotating machines or electrical generators (e. g. wind and water power generators) are impregnated with resin. A new technology using the heating effect of current is investigated. The high efficiency of heating with the joule effect results in quick heating of stator leading to fast gelling of the resin, which implies low emission.
De-lacquering as a service
Development of the service of de-lacquering in industrial plants on the basis of pulsed high pressure water with a new, energy efficient high pressure pump. Further possible applications will be searched for and evaluated.
