Automated Controlled-Flow Air Infiltration Measurement System

摘要

An automated, controlled-flow air infiltration measurement system is described. 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: concentration decay, continuous flow in a single chamber; and continuous flow in a multichamber enclosure. Problems associated with the use of nitrous oxide as a tracer gas are described. (ERA citation 03:048213)
