Measurements of contaminant dispersion in ventilated rooms by a passive tracer gas technique

Abstract

During recent years the interest in the passive tracer gas technique has grown rapidly. The method has mainly been used in the field for measurements of air infiltration rates in buildings. This paper describes measurements of the contaminant dispersion in a ventilated room using a passive tracer gas technique and the results are compared with the results from a conventional method. Vertical profiles of concentration in the middle of the room have been measured at different ventilation air flow rates and different locations of the tracer gas source. The results showed good correspondence between the methods within an accuracy of {+-} 10-15% in large parts of the room. In regions close to the tracer gas sources the differences were larger. The results gave at the same time recommendations for the use of the passive tracer gas technique for measurements of the air infiltration rates in buildings. (au)
