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)
R : coefficient x H
S :hR², where h = 3.14
|Size of Blade||H (m)||S (m²)||Coefficient|
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
STREAM OF WIND MOVEMENT
The stream of wind movement is smooth and steady. The delivery and coverage area is maximum.
Ceiling Fan installation height ≥ 30 cm.
Height from floor 2.5 ~ 3.0M
Blade distance between wall side ≥ 1M
Room size too small. The stream of wind movement is not steady and air turbulence is created. This condition can cause the fan wobbling and noise may also be created.
To install small size ceiling fan (120cm / 48”).
The ceiling fan installation height < 30cm (too close to the ceiling). The stream of wind is inferior and efficiency drops and noise may be created.
To increase the ceiling fan pipe > 30cm (minimum).
