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.
Distributed energy resources like solar panels and wind turbines are increasingly replacing fossil fuel energy sources. Due to their natural fluctuations they cause imbalance in the power grid when their production does not overlap with demand. Thus, there ...
In this article, three different modes of a novel integrated system would be evaluated by the application of high temperature Thermal Energy Storage (TES) to produce electricity, cooling, and freshwater. Freshwater is produced using the reverse osmosis (RO ...
Temporal dynamics of urban warming have been extensively studied at the diurnal scale, but the impact of background climate on the observed seasonality of surface urban heat islands (SUHIs) remains largely unexplored. On seasonal time scales, the intensity ...
This study focuses on two of the impacts of global warming (increasing temperatures and increasing vapor pressure deficit - VPD) on plants water status. Three different tree species were selected and young three-years-old trees were placed in conditioned c ...
The goal of the current article is to suggest a novel solar system to produce power, fresh water, and cooling. As solar energy is unavailable at nights, a novel thermal storage system (TES) based on phase change material (PCM) is used to store the required ...
Many countries and cities in the world have pledged to drastically reduce their CO2 emissions during the next decades. Given the high degree of urbanization in occidental society, district energy systems present a high potential to increase the efficiency ...
The present research aims at understanding the mass transfer of air into water in a reversible pump turbine operating in condenser mode. In particular, the diffusion of oxygen through the water free-surface both in the vaneless gap between the impeller bla ...
The focus and challenge for energy engineering in the context of rapid climate change is summarised by the Europe 20-20-20 targets, committing to a reduction in energy consumption of 20%. The most logical approach to achieve these goals is to target the mo ...
Industries consume large quantities of energy and water in their processes which are often considered to be peripheral to the process operation. Energy is used to heat or cool water for process use; additionally, water is frequently used in production supp ...
Emerging energy-efficient, oil-free radial centrifugal compressors seem promising for small to mid-capacity air conditioning and refrigeration applications. Compressor design must balance trade-offs among impeller diameter, bearing type, and refrigerant se ...
