    Abstract

    A description is presented of an automated, controlled flow air infiltration measurement system. This system measures total air flow, a volume per unit time, due to infiltration in a test space. Data analysis is discussed and the mixing problem is analyzed. Different modes of operating the system are considered: (a) concentration decay, (b) continuous flow in a single chamber, and (c) continuous flow in a multichamber enclosure. Problems associated with the use of nitrous oxide as a tracer gas are described.
