DE-93-07-2 -- Development of a Measurement System for Multizone Infiltration PDF

Although there has been much effort to design highly airtight structures, adequate ventilation for them has not received proper attention and an understanding of interroom ventilation is lacking. In the present work, we have developed a measurement system, using the multigas decay method, to measure multizone infiltration. The technique enables us to easily carry out on-site multizone infiltration measurements. A simple computer program to predict interroom airflow patterns has been developed, and a scale model house was constructed to compare experimental and simulation data. They are found to be in good agreement. Ventilation measurements are made in a real residential space. The results obtained demonstrate the effectiveness of the present method.
