Select the appropriate topology while taking account of the following:
Feature
Pipe length
Number of bends
Number of branches
Number of aspirating holes The number of aspirating holes can be used to adapt
System balance
Distribution
Size of aspirating hole in
the end cap
Examples of different topologies used in the same room
I-topology
with one pipe
Information
A short pipe length equals a short response time.
Fewer bends mean fewer curves and a better
laminar flow.
Each branch links airflows.
the sensitivity to the room concerned.
The use of multiple pipes results in improved system
balance.
The shorter the pipes, the better the distribution of
the aspirating holes.
The aspirating hole in the end cap can be used to
control the airflow in the pipe.
U-topology
with two pipes
Double U-topology
with four pipes
