INSTALLATIONSECTION 3
COLLECTOR LAYOUTS
If collectors are installed in parallel either in the same field, or due to location separate fields,
the flow balancing should be addressed. It is recommended that if pipe runs are such that
the resistance through each circuit could lead to unbalanced flow, some form of flow
regulation device should be installed on the return lines of each leg.
Due to the need for limiting the requirement for roof access, it is recommended that the flow
regulator devices are located in the plant roof or an easily accesable area. This will mean that
long pipe runs are required on the return lines before the pipes reconnect. (see Fig 3). Flow
regulation should only be required when the pipe (see page 12) runs between the collector
fields for panels local to each other there should be no need for regulation. For collectors local
to each other there should be no need for regulation. The collectors are capable of
withstanding small variations in flow.
PERFORMANCE and LOCATION.
The collectors could be split into fields (see basic operation) due to performance, site location
o
r both. If separate fields are required these can be arranged into either series or parallel
confirmations.
