In the previous paper, theoretical consideration of the tracer gas experimental method that uses dynamic steady state concentration was made. In this study, the feasibility of the tracer gas experimental method was examined based on a laboratory experiment. It was confirmed that a dynamic steady state concentration in case of negative generation of tracer gas corresponds to the age of air in an open-air system. The sum of dynamic steady state concentrations in case of positive generation of tracer gas and that for negative generation in the air recirculating part of a room is similar to the steady state concentration in an open air system.

Fundamental Study on a Tracer Gas Experimental Method that uses Dynamic Steady State Concentration and can be Applied to an Air Recirculating System
