| 摘要 |
The invention relates to a centrifugal fan for use in devices and systems in heating, cooling (refrigerating), and ventilating technology, which have a high flow resistance. In the new centrifugal fan, the pressure coefficient (pressure factor) is increased by changing the suction opening and the position of the fan impeller relative to the suction opening. <IMAGE>
