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.
During the last years, permanent magnets synchronous motors have become a reference in the industrial world, both from the economical and the technical point of view, because of their very good performance in both regards. Thus, application of specific met ...
In a rotary magnetic refrigerator a porous ring is turning in and out of a magnetic field region. The adiabatic demagnetization of the magnetocaloric material produces the "cold energy". This is described by a discontinuous temperature decrease, known as a ...
This paper presents a methodology aimed at improving the energy efficiency of a brewery applying process integration techniques. The different steps of the analysis are presented. The first step is the identification of the process energy requirements and ...
At the LENI a heat pump model has been developed, which aims to simulate a single state compression heat pump in both steady state and transient regime. For gaining the experimental data and for the simulation the same set of input data is used. The goal i ...
In a rotary magnetic refrigerator, a porous ring is turning in and out of a magnetic field region. At the outlet the adiabatic demagnetization of the magnetocaloric material (refrigerant) produces the "cold energy". The induced cold is described by a corre ...

The invention concerns a magnetocaloric device, especially a magnetic refrigerator, a heat pump or a magnetic power conversion machine comprising at least a permanent magnet assembly (4, 11) for generating magnetic flux, a rotating ring (2) coaxially dispo ...
We continue the development of high-order accurate thin layer approximations for time-domain electromagnetics and focus in this paper on a new family of models for thin transmission layers. The thin transmission layer approximations are valid for general i ...
Magnetic refrigeration is a new environmentally benign technology and a promising alternative to conventional vapor-cycle refrigeration. The household refrigerator without a freezing compartment shows very good prospects for a successful application. This ...
Process integration methods allow one optimizing industrial processes. The main goals are decreasing energy demand and operating costs as well as reduction of pollutants emissions. High fuel costs promote installation of heat pumps. In a heat pump process ...
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 ...
