Abstract
These airflows can be evaluated by using the multiple tracer gas techniques. The balances of tracer gases are expressed by a set of differential equations. In such a case, we have to obtain the suitable time T, to calculate the interzonal airflows using the above equations and mass balance equations of airflow rates when the tracergas concentrations were measured in each rooms.In this paper, we have a set of mathematical solutions for changes of gas concentration for 2 Rooms Model and a set of mathematical solutions for changes of gas concentration for 3 Rooms Model. These solutions are approximated by exponential functions according to the number of rooms.
