Outdoor air delivery rates to occupants and age of air.

Summary

A simple and accurate technique to directly measure the outdoor air delivery rates to building occupants is presented. A few measurements of tracer concentrations are sufficient for calculation. Experimental results show that the calculated outdoor air change rates from the tracer gas experiments agreed well with the outdoor airflow rates measured independently by nozzles. A relationship between the local outdoor air exchange rate and the mean age of air was derived. The proposed technique provides a way of simplifying the measurement of mean age of air and correcting experimental errors.
