説明

The interzonal airflow rates in an actual-sized test house were measured by using the multiple tracer gas technique. Cylinders were installed within the walls of the test house so that the volume of infiltrated and exfiltrated air-leakage could be varied. 1. The values obtained by the multiple tracer gas technique had errors of 20% to 30%, but the degrees of accuracy in the case of 4-zone model and 5-zone model were similar to those for a 2-zone model and 3-zone shown in previous reports. 2. When the degree of airtightness was low (e.g., 5 cm^2/m^2), the calculated airflows were less than those in other tests. 3. The calculated results are almost equal between 4-zone model and 5-zone model even if the volume of the interconnected space, such as stairs, is not considered in the calculation of airflow rates between zones.
