Accurate boiler models for large scale simulation

Today, the development of computer makes the accurate performance analysis of complex system by simulation available for most of the research community, and very soon for every concerned engineer. However, the simulationist approach requires a strong investment on the modelling of the system behaviour. This paper deals with a basic contribution on domestic hot water gas or fuel oil boiler models, usable for large scale simulation involving building and HVAC. This model is primarily issued from a task in International Energy Agency Annex 10 [4] and is now developed at the CSTB for a large scale analysis on the experimental building of Gaz de France, Paris.
