Connection of
the medium piping
The connection of the lines
on-site takes place on the front
side of the unit (operating side).
For the purpose of servicing,
connections must be equipped
with shut-off valves and flow
volumes adjusted using valves
for hydronic balancing.
Additional automatic bleed
valves are to be provided
in the supply and return at
the installation's highest point.
The medium piping may not
exert any structural load on
the unit.
The line connections may
not generate any thermal or
mechanical stresses on the unit
(cool lines or hold in place with
a second tool if required).
If the unit is at first to be
operated with only a part of
the entire system, the medium
flow for the missing system
components is to be simulated
using valves for hydronic
balancing.
The pipe sizing is to be
designed such that the
stipulated minimum flow
volume is achieved.
Minimum/maximum flow volume
The cold water generator's
circulation pump generates
a constant medium flow.
The result is a loss of pressure in
the system and in the cold water
generator. The differential pressure
or flow switch in the chiller
measures the pressure loss over
the evaporator or the flow
of the medium and switches
the unit off if the flow rate drops
below the minimum medium
volume.
The medium flow rate limit
may likewise not be exceeded
(maximum flow volume). A 3-way
valve with bypass and a hydraulic
compensator to establish a primary
and secondary circuit or a volume
dependent bypass are necessary to
ensure a constant flow volume.
Valves for hydronic balancing
The calculated individual pressure
losses in the pipeline network
layout for each individual unit are
adjusted to the entire system with
valves for hydronic balancing to
be provided on-site. The nominal
flow rates for the medium
adjust to the necessary values as
a consequence of the pressure loss.
The display should be able to be
shut off.
Temperature sensors are located
in the chiller's medium inlet
and outlet. Sensor values can
be queried via the controller.
Medium piping
Medium piping can be made of
copper, steel or plastic. To minimise
pressure losses, only streamlined
fittings should be used.
When designing the layout,
the large flow volumes in cold
water systems, high pressure
losses in connection with water-
glycol mixtures and the cold water
generator's minimum flow volume
must be taken into account.
To adjust the circulation pump, we
recommend that a main hydronic
balancing valve is provided in
the vicinity of the unit.

The lines are to be insulated against
vapour diffusion and, if necessary,
the current German energy-saving
ordinance (EnEV) must be observed.
UV resistance must be realised outdoors
Fill and drain connection
A connection should be
provided in an area safe from
frost for the draining of pipe
lines (especially if water is
used as a medium). Applicable
local disposal ordinances must
be observed if glycol is used.
Pressure and temperature displays
The pressure and temperature
displays to be installed on-site
at the intake and outlet serve
to set the medium flow rate.
