Sustainable Development Based Methodology for the Optimized Integrated Design and Operation of Energy Conversion Processes and Networks.

A design methodology allowing engineers to consider simultaneously and from the earliest phases of design some of the key factors of sustainable development (pollution, life cycle data) has been developed and successfully demonstrated on two examples of in ...

Behaviour of central plasma relaxation oscillations during localized electron cyclotron heating on the TCV tokamak

Olivier Sauter, Timothy Goodman, Jean-Marc Moret, Ivo Furno, Minh Quang Tran, Holger Reimerdes, Jean-Philippe Hogge, Henri Weisen, Antoine Pochelon, Roland Behn

During initial studies of ECRH in the TCV tokamak, non-standard central MHD activities, such as humpbacks and saturated and inverted sawteeth, have been observed while changing the heating location, the ECRH power, the plasma shape and the safety factor. F ...

Flow Boiling in Horizontal Tubes. Part 2; New Heat Transfer Data for Five Refrigerants

John Richard Thome, Daniel Favrat

A summary of a comprehensive experimental study on flow boiling heat transfer is presented for five refrigerants (R134a, R123, R402A, R404A and R502) evaporating inside plain horizontal, copper tube test sections. The test data were obtained for both 12.00 ...

An Environomic Approach for the Life Cycle Modeling and Optimization of a District Heating Network Based on Centralized and Decentralized Heat Pumps (Part II: Application).

Daniel Favrat, Vinicio Curti

Although heat pump based district heating is often an obvious solution, adapting the delivery temperature to the most exigent users is detrimental to overall system performance. This pitfall can be avoided with a centralized plant of heat pumps, cogenerati ...

Environomic Optimization of District Heating Network Systems with Both Centralized and Decentralized Heat Pumps.

Daniel Favrat, Vinicio Curti

In Switzerland like in many countries, many of the populated areas are located close to lakes or rivers, offering a large potential for the use of heat pumps. Although district heating is an obvious solution, adapting the delivery temperature to the most e ...

Comparison Between a Single Stage and a Two Stage Air to Water Domestic Heat Pump with one Variable Speed Compressor.

Daniel Favrat

Replacing conventional boilers by air to water heat pumps represents a major market opportunity and a contribution to more sustainable heating approaches. However, such retrofit situation impose tough technical requirements which must be met in order to de ...

Stirling-Wärmetransformator für die Beheizung von kleinen und mittleren Wohnbauten.

Daniel Favrat

Several years ago it has been demonstrated experimentally and verified theoretically that Vuilleumier heat pump systems (a combination of a Stirling engine with a Stirling heat pump) can be supercharged periodically by means of an attached resonance tube, ...
