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.
This paper investigates the energy efficiency improvement of an industrial site through thermodynamic analysis of distillation columns together with the total site integration (TSI). Unlike the existing methods which consider the distillation unit exclusiv ...
This study aims to improve the energy efficiency of an industrial site by applying the thermodynamic analysis of distillation columns together with the total site integration (TSI). Several methods have been proposed in the literatures for the thermodynami ...
This study deals with a type of thermally driven heat pumps that consists of a reverse Rankine heat pump cycle, the compressor of which is driven by the turbine of a supercritical Organic Rankine Cycle (ORC). The application is residential heating (domesti ...
Nowadays, one of the main alternatives for a more rational use of energy in heating applications is the heat pumping technologies. The market is dominated by two kinds of heat pump systems: the electrically driven vapor compression heat pumps (EHP), which ...
This report accounts for making the heat transfer model in co-rotating scroll compressor. This mathematical model was proposed according to the working principle of the compressor, its geometry and basic thermodynamics’ laws. Previous papers and reports, r ...
Multistage heat pumps are one of the most efficient technologies for delivering heat at temperatures below 100°C, Thanks to their fairly high exergy efficiency. In the recent years the development of radial compressors mounted on gas bearings have unlock t ...
A new finned reciprocating air compressor model is developed recently for compressed air energy storage. First the mechanism of operation of the new compressor is described. The complexity of the design encouraged us to develop the model based on the bond ...
Throughout the years LENI-EPFL spent a significant part of its research activities on heat pumps be it for industrial heat recovery or for domestic or district heating and cooling. Methodological contributions include the improvement of the formulation of ...
The concept studied in this work is a low power ORC-ORC heat pump system (providing about 20 kW heat at the condenser) and that is composed of an ORC power cycle driving a reversed ORC heat pump cycle, both cycles using the same fluid. The centrifugal comp ...
The report describes the implementation of a radial micro-compressor in the dynamic modeling software PSE gProms, the development and the implementation of a two-phase flow pipe model, and the preliminary design of a two-phase flow dynamic heat exchanger ...
