Title The measurement of ventilation parameters by means of tracer gas techniques and a microcomputer
Bibliographic information 1984, Vol.28, No.2, p.203-210. Illus. 15 ref.
Abstract A tracer method was developed for the evaluation of workplace ventilation. Nitrous oxide or freon 12 (dichlorodifluoromethane) were used as tracers. The concentration of the tracer gas was measured using an infrared analyser. A microcomputer was used for data calculation, display and storage. 3 applications are described: determination of the capture efficiency of a local exhaust hood; evaluation of air leakage of a room; measurement of local ventilation rates in a large industrial plant.
