Guide for ceiling fans
Design of ceiling fans in school rooms and classrooms
In Switzerland and France, ceiling fans have long been standard in schools. Relatively low investments are offset by high benefi ts in terms of improved thermal comfort for teaching staff and students. In a 9 x 7 m classroom with a ceiling height of 3.20 m, thermal comfort is to be improved. The designer wants to use the Eco Neo III model with a size of 132 cm.
According to Fig. 10 on page 9, this results in an effective area in the secondary air flow of 2.4 x 1.32 m, i.e. a circular area with 3.168 m Ø. These circular areas are distributed accordingly on the adjacent floor plan. The distance ceiling - blades should be at least 0.3 x fan Ø, i.e. 0.396 m, according to Fig. 6 on page 7. For reasons of appearance, the planner decides that the blades of the ceiling
fans should be arranged at 2.7 m. The distance between the ceiling and the fan is then calculated from the dimensions table on page 126,. From the dimension table on page 126, this results in the use of a 60 cm ceiling rod that is shortened by (810 mm - 500 mm) 310 mm.
A central wall control FB-FNK ECO Hotel A #86200, which is mounted on the wall near the teacher‘s desk, is used to control the fans together.
Alternatively, a version of the fans with 0-10 VDC interface is used, which can be controlled in speed and running direction via the building management system or the wired wall potentiometer POT-R 0-10V #86111.
