6.6 Chilled water connection
INFOrMATION
To avoid any misunderstandings:
the designation "water inlet" and "water outlet" are chosen, seen from the chiller.
At the water outlet, the chilled water is provided from the chiller.
The connection piping should consist of P235 or similar steel, as the water piping in the chiller,
to avoid the risk of corrosion at the transition to the external piping. The connection is carried
out standard wise in the shape of Victaulic
®
connections.
We recommend the following good practice:
• install a water bypass to be able to carry out work at the chiller (without having to disconnect it
from the pipework)
• connect the pipe with adequate supports, so that it weight is not borne by the chiller
• install adequate anti-vibration pipe joints to avoid the transmission of structure-borne noise
• insulate the pipes of the external system, if they are in contact with external air, to prevent the
introduction of heat from the ambient air as well as possible
WArNING
The connection piping must be connected to the chilled water lines of the chiller free of
mechanical stress.
