Definitions

  • centrifugal fans use a centrifugal force to take in air in an axial direction, and to blow the air outward in a radial direction.
  • the air blown out from the centrifugal fan has an airflow of an axial direction component directed from an intake side to a counter-intake side.
  • L/D should be set to 0.12 and over (0.15 in the present embodiment)
  • the fan inlet opening angle ⁇ 1 should be set to from 55° to 85° (65° in the present embodiment)
  • the fan-outlet-opening angle ⁇ 2 should be set from 15° to 45° (35° in the present embodiment)
  • the fan advancing angle ⁇ should be set from 4° to 10° (7° in the present embodiment).
