Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The substitution of old refrigerants in refrigeration systems, heat pumps and organic Rankine cycles for heat recovery, request a good knowledge of heat transfer properties of substitute fluids. The test measurmements in LENI test facility (concentric tube ...
Pinch analysis is a powerful analysis and design methodology for the integration of thermal processes. Although originally developed for and applied to continuous industrial processes, pinch analysis can be equally beneficial when applied to buildings. In ...
The objectives of the present work is to theoretically and experimentally demonstrate the advantages of a two-stage cycle equipped with an economizer and single variable speed compressor for heat pumps using air as cold source. Furthermore, an efficient de ...
PINCHLENI is a software for energy integration of industrial processes based on Pinch Analysis. The software in version 2.0 allows: - the visualisation of the composite curves and the grand composite curve - the choice of the optimal pinch based on economi ...
In the previous issue of the IEA Heat Pump Centre Newsletter (Vol, 12, No.3, pp. 29-31), an article by these authors described the use of pinch analysis (also known as pinch technology) in a buildings application. This article describes a similar procedure ...
For the most part, district heating demands can be met by an appropriate integration of cogeneration and heat pumps units provided that advantage is taken of the fact that many urban regions are concentrated around surface waters. Such an integration resul ...
There is a growing need for the analysis of energy systems not only on the bases of their operational life, but also on the basis of considerations for the manufacturing and recycling phases. Environmental and to a lesser extent resource scarcity factors s ...
A complex heating and cogeneration plant including two 3.9 MWth ammonia heat pumps and two 3 MWel gas turbines with heat recovery boilers and three strage tanks has been in operation since 1986. This paper is a result of an expreimental evaluation during t ...
The pinch analysis method is a useful tool for the energy integration of industrial processes (structuring and simplification using simple guidelines). The pinch analysis method, extended to include exergy factors, falls within the framework of a global mu ...
For the most part, district heating demands can be met by an appropriate intergration of cogeneration and heat pumps units provided that advantages is taken of the fact that many urban regions are concentrated around surface waters. Despite the fact that t ...
