||A technique to use data loggers to measure effective ventilation and air exchange rates by carbon dioxide tracer
||Sep. 1994, Vol.55, No.9, p.833-835. Illus. 7 ref.
||An electronic timed sampling valve was used to collect air alternatively from the room exhaust and the breathing zones of occupants. The timed valve provided a data logger with a data set for each location. The data were fitted to an exponential one-compartment clearance model. The fitted data were used to calculate air exchange, mean air life, half-life of room air, ventilation effectiveness and correlation of fit. The technique used ambient carbon dioxide gas concentrations as a natural tracer, or compressed carbon dioxide as a pulse-inject tracer as a pulse-inject tracer gas.
