Air accumulation in the condenser owing to insufficient output of air extractor can increase the terminal temperature difference and the airpressure component.
This method is based on the measurement of the rate of air flow through a given area of fabric by a given pressuredifference across the fabric.
这个方法是基于对空气流速的测量：在一块既定面积的面料上，通过面料两边不同的压差来获得。
