Abstract

An infrared absorbing tracer gas technique using nitrous oxide has been developed by the Architectural Sciences Division to illustrate patterns of air flow from air-conditioning supply air diffusers. Air flow patterns are recorded in real time on videotape through the use of infrared cameras and an IR opaque gas. By identifying faulty air circulation, the quality of the interior environment may be improved. The approach was first recognized by Public Works Canada in 1978 as having great potential as another diagnostic technique for improving Canadian building performance. The tracer gas technique comes as an extension of the developmental work in thermographic diagnosis of enclosure deficiencies done by Public Works under the direction of Peter A.D. Mill. 1,2,3
