According to the regulations, the cross-section flow rate is less than 2. In fact, it has no other function except the connection. If it is necessary to press the muffler. The air supply determines the wind speed and the size of the air supply outlet according to the air supply volume and installation position. The area of the return air outlet is determined according to the return air volume. The return air generally has a small wind speed of 2, and the length and width are determined according to the installation position. According to the above, select the type, and then calculate the wind resistance of the long pipe, as long as the static pressure outside the unit is small.
