About this Item

Print on Demand. This book introduces a method for measuring air infiltration rates in buildings using sulfur hexafluoride (SF6) as a tracer gas. The author describes a system for automating the operation of a gas chromatograph, which measures the concentration of SF6 in air samples. The system includes an automated sampling system and a tracer injection system. The author provides a detailed description of the system, including the calibration procedure and the instrument response. The author also presents an analysis of the departure from Beer's law, which is used to calculate the concentration of SF6 in air samples. The book concludes with a discussion of the limitations of the system and the potential for further development. This book will be of interest to researchers and practitioners in the field of building science and energy efficiency. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.

About this title

Synopsis

A Prototype Semi-Automated System for Measuring Air Infiltration in Buildings Using Sulfur Hexafluoride as a Tracer Learn how a small gas-chromatograph system automates tracer gas measurements to estimate how air moves through a building.

This report describes a practical setup that introduces SF6 automatically into a building’s air and tracks its buildup and decay. It explains how calibration, measurement timing, and different sampling methods affect the accuracy of infiltration rate estimates, including when central HVAC changes the results. Real-world testing in a four-bedroom house shows how the system performs and what limits exist for unattended operation.

• How tracer gas (SF6) is used to measure air infiltration rates in buildings


• What the automated system looks like and how it operates with a small gas detector


• How calibration, response drift, and measurement timing influence accuracy


• Practical test results, including different sampling methods and common issues

Ideal for readers of building science, ventilation studies, and engineers seeking a hands-on view of automated tracer-dilution measurement techniques.
