Thermal Behaviour of a Building and Its Heating System in Variable Conditions

摘要

The research for energy conservation in the field of space heating leads, at first, to an increase of the thermal insulation level of buildings. This strengthening of insulation is not, however, the only way to achieve significant conservation: a heating system with a regulation mode more fitted to the needs, a better use of the free heat plan contribute to the decrease of consumption and improvement of comfort. In order to determine the best solutions to be selected, the D.E.T.N. of Gaz de France has created the Serval computer program (building simulation in variable conditions) which allows a simulation of the thermal behavior of a building and its heating system in variable conditions. This paper describes the program and gives a few applications examples. The ''Serval'' computer program should make it possible to examine the thermal behavior of any buildings in variable conditions for the purpose of finding out how to achieve a maximum level of comfort for the lowest possible consumption. The research currently in progress relates to standard arrangements of certain heating systems. The ''Serval'' program will subsequently be in a position, following the addition of new sub-routines, to be extended to other heating systems, such as for example: installations equipped with energy-saving devices (recuperator, heat pump, etc.); and processes using solar energy, with gas as an auxiliary, to meet some of the premises' heating requirements. It will also be used for the purpose of investigating buildings other than residential ones (tertiary applications). (ERA citation 11:000831)
