F-10 Study on Measurement of Air Flow Rate on Domestic Ventilation Systems : Part.1 Research and experiment of measurement methods and instruments

Abstract

The purpose of this study is to verify and to estimate measurement methods of air flow rate on domestic ventilation systems employing small diameter ducts. The experiments, which focus on the accuracy in the field, were conducted by using 6 measurement instruments. According to the experimental results, measurement instruments applying to the k-factor method have high accuracy and airflow meters using hot wires have relatively high accuracy for suction air.
