exigences d'évacuation
FR
Configuration d'évacuation simple
(deux coudes de 90° seulement)
Lorsque la configuration de l'évacuation exige plus qu'un coude de 90°, les formules suivantes
s'appliquent :
Formule 1 : H
< 3,5V
T
Formule 2 : H
+ V
T

Exemple :
V
= 4 PI (1,2m)
1
V
= 1,5 PI (0,5m)
2
V
= V
+ V
= 4PI (1,2m) + 1,5PI (0,5m) = 5,5 PI (1,7m)

H
= 0,03 (quatre coudes 90° + un coude 45° - 90°)
O
= 0,03 (90 + 90 + 90 + 90 + 45 - 90) = 9,45 PI (2,9m)
H

+ H
= 5,5PI (1,7m) + 9,45PI (2,9m) = 14,95PI (4,6m)

H

= 14,95PI (4,6m) + 5,5PI (1,7m) = 20,45PI (6,2m)

14,95 PI (4,6m) < 19,25 PI (5,9m)
Formule 2 :
H
T
20,45 PI (6,2m) < 24,75 PI (7,5m)
Puisque les deux formules sont respectées, cette configuration d'évacuation est acceptable.
