Abstract

This paper describes an ozone-based tracer gas system that can be used to create models of indoor air flow. Ozone is generated via corona discharge using a parallel resonant DC-DC converter, and ozone concentration is monitored using a novel low-noise amplifier. Power-line carrier modems are used to coordinate the generation and detection of ozone. Intelligent digital control strategies for the generator are developed using the requirements of several different air flow tests.
