[AIVC, Air infiltration and ventilation glossary, 1992]:a Tracer gas method for measuring ventilation rates, whereby an automated system injects tracer gas at a rate required to maintain the concentration of tracer gas within a room or zone at a fixed, … Continue reading →
tracer gas technique, constant flow/emission
[AIVC, Air infiltration and ventilation glossary, 1992]:a Tracer gas method for measuring ventilation rates whereby tracer gas is continually emitted at a uniform rate. The equilibrium concentration of tracer gas in air is then measured.
