E-15 Study on Measurement of Air Flow Rate on Domestic Ventilation Systems : Part.2 Experimental tests of measuring accuracy on terminal devices by using air flow measurement instruments employing hood

Abstract

The purpose of this study is to verify and to estimate measurement methods of air flow rate on whole house ventilation systems in situ. The experiments were conducted on domestic air terminal devices by using 6 air flow measurement instruments employing hood. According to the experimental results, measurement instruments have relatively high accuracy on air inlet terminal devices or even on air outlet terminal devices by using lager hoods.
