Im Rahmen des vom Bundesministerium für Wirtschaft und Energie (BMWi) geförderten Projekts „ETA-Fabrik“ am Institut für Produktionsmanagement, Technologie und Werkzeugmaschinen (PTW) der Technischen Universität Darmstadt konnte die Energieeffizienz von Motorspindeln als Hauptenergieverbraucher von Werkzeugmaschinen durch Einsatz der Synchronreluktanztechnologie gesteigert werden. In der Konsequenz ergeben sich weitere Energieeinsparpotenziale und produktionstechnische Vorteile durch eine gesamtenergetische Betrachtung der Werkzeugmaschine mit Kühlsystem und intelligentem Spindelthermomanagement.   As part of the ‘ETA-Fabrik’ project funded by the BMWi, the Institute of Production Management, Technology and Machine Tools (PTW) of the TU Darmstadt has used synchronous reluctance drives to increase the energy efficiency of motor spindles as main energy consumers of machine tools. Subsequently, new opportunities for energy savings and advantages for the manufacturing process arise by taking a holistic view on machine tools including the cooling system, proposing an intelligent spindle thermal management.

Vapor Compression Refrigeration

For next-generation sustainable electronic systems, such as high-concentration photovoltaics arrays and high-density super-computers, two-phase cooling technologies are being explored to significantly reduce heat resistance from electronics’ surface to the ambient. Lower electronics operating temperatures lead to higher energy conversion or computation efficiency; therefore, thermal management, especially dynamic thermal management, is able to bring great potential to energy-efficient electronic system operation. These large-scale electronics cooling systems normally include multiple, distributed, and transient heat sources. Multi-evaporator vapor compression refrigeration cycle provides such a promising cooling solution. Due to the complexity of multiple evaporator structure, its transient analysis and active control become very challenging. This paper applies our previous distributed heat exchanger modeling techniques to study the dynamics of multi-evaporator refrigeration cycles. A comprehensive first-principle multi-evaporator vapor compression cycle model is formulated for its transient analysis. Some preliminary expansion valve control results are presented to show the excellent active electronics cooling capability. This general tool is expected to bring instructive guidelines for the optimal design and operation of energy-efficient transient electronics cooling systems with multiple heat loads and hot spots.
