Ceiling Fan Installation / Selection Guide
INSTALLATION OF ONE UNIT CEILING FAN
The main features of a ceiling fan is to move the entire air in the room, not creating a local wind as in other fans.
To determine the model and mounting position, consider the condition below :
H : distance from blade to floor (m)
R : radius of effective floor space of wind spread (m)
S : effective floor area (m2)
Calculation Formula :
R : coefficient x H
S : hR2 , where h = 3.14
| Size of Blade | H (m) | S (m2) | Coefficient |
|---|---|---|---|
| 120 cm | 2.5 | 8.3 | 0.65 |
| 150 cm | 3 | 12.5 | 0.66 |
CALCULATION IF MORE THAN ONE UNIT REQUIRED
L : Distance between Ceiling Fan to another (pitch in M)
A : Distance of overlapping air throw between fan
B : Distance between tip of fan to wall
BL : Blade length (M)
L : (RX2) – 0.4, where 0.4 is maximum allowable overlapping of air throw between fan
L : (RX2) – 0, if minimum A = 0
To calculate B = R – BL
