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 semester project follows a previous project at LENI-EPFL ad aims at finding the best optimization approach in terms of heat pump integration in industrial processes. The multi-objective optimization method chosen seeks the minimum of both operating an ...
There is a broad range of techniques available to the engineer and that should be considered in a retrofit project to enhance the energy efficiency of an operating process. The two best known techniques and most often utilized are internal heat recovery by ...
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 ...
Described is a method of manufacturing a module with long-term stability even though it contains a non-heat-resistant material, in particular a photosensitizer. Two glass plates (1, 2) are connected to each other round their edges with an edge-sealing stru ...
This project inserts itself in improving the understanding of the sensitivity of the dTmin against the parameters that influence it. It is also aimed at helping to improve OSMOSE, a platform designed for the study of energy conversions systems. Three econo ...
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 ...
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 ...
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 ...
Process integration methods aim at identifying options for heat recovery and optimal energy conversion in industrial processes. For the heat cascade, it is assumed that any heat exchange between cold and hot streams is possible, but due to industrial const ...
This paper presents a general, practical and operational methodology to improve energy efficiency of processes through a holistic approach. The required methods and tools have been developed based on a systemic approach of process energy integration and en ...
