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.
One of the key sources of uncertainty in building simulation relates to the presence and behaviour of occupants. Fortunately, several academic groups have been working to address this uncertainty, particularly in relation to the use of windows and the corr ...
Ce document présente la réalisation et les essais d’un générateur de gaz chauds offrant la possibilité de simuler les conditions de sorties d’une pile à combustible SOFC plane. Le document fait également part du design d’un banc d’essais visant à utiliser ...
Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...
The presence of oil in domestic heat pumps is an obstacle toward higher efficiency, particularly for enhanced surface evaporators and for advanced concepts based on two- stage cycles. Very compact direct driven radial compressors supported on oil-free beari ...
Publications on magnetocaloric materials, magnetic refrigerators, magnetic heat pumps and magnetic power conversion machines contain experimental results as well as solutions obtained by physical modelling, analytical and numerical calculations. Whereas ma ...
International Institute of Refrigeration IIR-IIF2009
Heating and cooling will more and more rely on heat pumping in order to enable a more rational use of energy. The further development of domestic and small industrial multi-stage heat pumps with enhanced performance is impaired by the presence of oil mixed ...
This paper presents a study of a residential (about 20kW) ORC-ORC (Organic Rankine Cycle) thermally driven heat pump. The system works with three different temperature levels similar to absorption heat pumps. The proposed concept is a hermetic system using ...
Concern for the environment has been steadily growing in recent years, and it is becoming more common to include environmental impact and pollution costs in the design problem along with construction, investment and operating costs. To economically respond ...
At present magnetic refrigeration shows a realistic potential to penetrate into some niche markets in the field of cold and hot "production". It is well known that a refrigerator for cooling and a heat pump for heating are machines based on the same princi ...
The present invention concerns a permeable-magnetocaloric material for a magnetic refrigerator, a heat pump or a power generator comprising at least a magnet assembly for the generation of a magnetic field, a body disposed at least partially in said magnet ...
