Experimental research of an air catcher’s performance

Studies the mechanical performance such as minimum start-up air speed, reaction time and ventilation performance of the catcher developed by the authors on the simple opening ventilation test-bed. Combined with the measured data of the wind speed and direction during the January and February 2008 in Beijing, obtains the integrated evaluation result that this air catcher can be used to realize the building ventilation without or with a little driving power more than 65% time in the winter of Beijing and achieve the aim of energy saving.
