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.
Although heat pump based district heating is often an obvious solution, adapting the delivery temperature to the most exigent users is detrimental to overall system performance. This pitfall can be avoided with a centralized plant of heat pumps, cogenerati ...
A design methodology allowing engineers to consider simultaneously and from the earliest phases of design some of the key factors of sustainable development (pollution, life cycle data) has been developed and successfully demonstrated on two examples of in ...
This paper aims to illustrate a new holistic modeling environment through a case study implementing a district heating system to supply four groups of users identified in the city of Tokyo. The holistic modeling environment, called DOME (Distributed Object ...
A more widespread usage of heat pumps would contribute to significantly reduce both local and global environmental impacts. This is particularly relevant within cities, where advanced integrated energy systems incorporating heat pumps and associated with d ...
Although heat pump based district heating is often an obvious solution from an energy standpoint, adapting the delivery temperature to the most exigent users is detrimental to overall system performance. This pitfall can be avoided with a centralized plant ...
A simultaneous optimization of the design and operation of a district heating, cooling and power generation plant supplying a small stock of residential buildings has been undertaken with regards to cost and CO?2 emissions. The simulation of the plant cons ...

In order to extend the application range of air-water heat pumps to high temperature residential heating systems, new small hermetic compressors with remodeled injection ports for vapor injection have successfully been tested in laboratory. The injection f ...
A new type of air-water heat pump has been developed with the aim to cover an extended application range in high temperature residential heating (for retrofitting existing oil or gas boilers in hydronic heating systems). The base heat output is about 10 kW ...
Providing heat pumps for the retrofit of fuel based boilers in residential heating, is a short or medium term challenge and a major opportunity for a substantial reduction of greenhouse gas emissions. While effective solutions for improved high temperature ...
