IfcFanTypeEnum
Definition from IAI:
Enumeration defining the typical types of fans.
The IfcFanTypeEnum contains the following:
- CENTRIFUGALFORWARDCURVED: Air flows through the impeller radially using blades that are forward curved.
- CENTRIFUGALRADIAL: Air flows through the impeller radially using blades that are uncurved or slightl forward curved.
- CENTRIFUGALBACKWARDINCLINEDCURVED: Air flows through the impeller radially using blades that are backward curved.
- CENTRIFUGALAIRFOIL: Air flows through the impeller radially using blades are airfoil shaped.
- TUBEAXIAL: Air flows through the impeller axially with reduced tip clearance and operating at higher tip speeds.
- VANEAXIAL: Air flows through the impeller axially with guide vanes and reduced running blade tip clearance.
- PROPELLORAXIAL: Air flows through the impeller axially and small hub-to-tip ratio impeller mounted in an orifice plate or inlet ring.
- USERDEFINED: User-defined fan type.
- NOTDEFINED: Undefined fan type.
