6.3 Necessary system components
Valve assembly (accessory)
In 2-conductor systems, cold or warm medium is
fed through the register in the unit and cold or
warm air can then be released. Control is provide
by the 3-way valve assembly
. It comprises the
electrically actuated valve head and the valve
body. If the head is electrically activated, it
actuates the body, which routes the medium into
the register. If the temperature is reached, the
head is switched off and the medium is fed past
the heat exchanger through the bypass . The
bypass serves to ensure the minimum medium
flow rate for the chiller.
The time between being fully open and fully
closed can be approx. three minutes.
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 hydronic bal-
ancing valves to be provided by the customer
. The
nominal flow rates for the medium adjust to the
values needed as a consequence of the pressure
loss.
Anti-freeze protection (accessories)
A water glycol mix is generally used as medium for
a cold water system. Depending on the use to
which the glycol type and quantity is put, the vis-
cosity changes, the loss in pressure increases and
the unit's cooling or heating capacity reduces. All
system components must be approved for use with
glycol.
NOTICE!
When disposing, the product requirements of
the glycol type used must be observed.
Diaphragm expansion vessel (MAG)
To avoid pressure fluctuations during standstill
because of temperature changes, diaphragm
expansion vessels filled with nitrogen (moisture
neutral) must be integrated in the system.
No moisture can condense in the nitrogen filler
.
Safety valve
Safety valves limit excess operating pressure due
to excess warming or overfilling of the operating
medium. The valve outlet requires unobstructed
draining into a drain line. Applicable local disposal
ordinances must be observed if glycol is used.
Automatic bleed valves
The unit has one or two manual bleed valves on
the collector pipe of the register
. The unit can be
bled separately after the system has been filled.
Automatic bleeding valves must also be installed at
the highest point in the collector line.
NOTICE!
Glycol tolerant air bleeding valves are neces-
sary when using media that contain glycol.
