6. Decommissioning
6.1 Decommissioning
When decommissioning a unit for a lengthy period of time, the
following tasks or activities are to be carried out:
Stop the energy supply (electrical lines and all media).
-
Drain all water from the heat exchanger
-
For equipment with an integrated switching cabinet, switching
-
cabinet heating should remain switched on.
Existing dampers must be driven closed or closed manually.
-
Remove contaminated filters.
-
De-water the humidifiers.
-
Regarding large ventilators decommissioned for a lengthy
-
period, if these are not occasionally rotated, bearing damage
can be expected.
General cleaning of components set for decommissioning.
-
The instructions in the individual chapters must be adhered to, as
well.
6.2 Dismantling and disposal
After its useful service life has run out, the equipment should be
professionally dismantled.
Prior to dismantling, it must be ensured that all energy lines
(electrical and all media) are switched off. No lines should remain
supplied with pressure, temperature or other energy.
Subsequent to this, it must be ensured that all operating media has
been removed from the system; no water, oil or refrigerant may
remain in the system.
All assembly components and operating media (e.g. oils, refrigerant,
brine) are to be disposed of in accordance with local regulations.
Metal and plastic parts should be sorted, separated and directed for
recycling.
7 Emergency Measures
7.1 Fire prevention
As a rule, local fire prevention regulations must be adhered to.
If the air conditioning system is part of a smoke-removal concept,
then the related guidelines must be adhered to.
Otherwise, in case of fire, immediately remove electrical power to
the equipment by interrupting all phases. Louver dampers should be
closed in order to interrupt the supply of oxygen and spread of the
fire.
7.2 Leakage of harmful substances
Due to its optimised design and construction, this Huber&Ranner air
conditioning system possesses a very low fire and smoke load.
None-the-less, if the construction materials used do catch fire,
toxicologically critical substances may develop. Additionally, smoke
related gases from the equipment can be discharged into the
control room.
For this reason, heavy-duty breathing protection equipment should
be used.
Water conducting assembly components can become un-tight in the
event of fire. Do not remain in the immediate vicinity of the danger
area.
