Techniques de mesure utilisant des gaz traceurs pour déterminer le taux de renouvellement d'air.

Sets out in some detail the fundamentals for constructing models for determining global air change in a space or a building and describes the principal measurement and evaluation techniques. Describes and illustrates diagrammatically an air change measurement installation developed in the context of investigations of air exchange with window opening. Gives a systematic analysis of its application capabilities and the measurement techniques used. Describes how the concluding error analysis makes it possible to evaluate the global error when determining air exchange using the tracer gas measurement technique.
