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.
In conventional refrigeration the use of the T S diagram to determine thermodynamic cycle performance is a well accepted tool. This method is based on a single state description of the gaseous refrigerant during its cycling. Devices filled with a magnetoca ...
The main objective of this theoretical study was to investigate under which conditions a magnetic energy conversion device (MECD) - utilizing industrial waste heat - is economically feasible. Furthermore, it was evaluated if magnetic energy conversion (MCE ...
In this study, a flat-parallel-plate active magnetic regenerator made of gadolinium is investigated. The coupling of a one-dimensional thermal model with a two-dimensional magnetic model is presented. The thermal model takes into consideration the magnetoc ...
A decentralized adaptive solar air conditioning system is presented, which contains usual air-conditioning equipment and a new module, designed with a honeycomb structure, containing phase change material for latent thermal cold and hot energy storage. Hea ...
Viene presentato un sistema d’aria condizionata adattabile, di tipo decentralizzato con tecnologia solare, che contiene normalmente un dispositivo d’aria condizionata e un nuovo modulo, progettato con una struttura a nido d’ape, contenente materiale a camb ...
The majority of cooling systems are based upon vapor-compression refrigeration technology. Its principle has been unchanged for more than a century. Miniaturization and competitiveness have been gained, but there’s still a need of alternative technologies, ...
This paper discusses the system performance of a magnetic heat pump with an active magnetic regenerator. The heat-transfer coefficient and pressure drop in the AMR are performed analytically. Measurements on the experimental magnetic heat pump test device ...
In magnetism literature, usually the applied or external field H-0 is taken to present the results of an investigation. But for certain purposes, it is advantageous to work with the internal magnetic field H that occurs inside a magnetic body. It is well-k ...
De nombreuses méthodes et outils sont aujourd’hui disponibles sur le marché pour permettre aux maîtres d’ouvrage d’analyser leur consommation énergétique, identifier de réelles pistes d’économie d’énergie et piloter plus efficacement leurs bâtiments. Pourt ...
Due to different temporal combinations of energy generation processes, the global warming potential (GWP) of energy supply evolves constantly. Despite this, the greenhouse gas (GHG) emissions related to the energy consumption in buildings are commonly asse ...
