4.0 OPERATION
4.1 Temperature Control
4.1.1 Temperature Pre-set:
Haskris has pre-set the glycol solution
temperature per customer specification.
On initial start-up apply actual heat load
and wait 30
– 40 minutes for temperature
to stabilize.
4.1.2 Allowable Adjustments:
The
following procedures are intended for
glycol solution temperature adjustments
only. All other control parameters are
factory set for optimum performance and
should not be adjusted. If it appears that
“tuning” is required, please contact
Haskris for further information.
4.1.3 Adjust Set point While
System is Running:
Make all set
point adjustments while chiller is running
under actual heat load.
Electronic (PID) Controller
4.1.4 Permissible Temperature
Settings:
Glycol solution temperature
range is 45°F to 60°F (7.2°C to 15.6°C).
If a temperature setting outside this
range is required, please contact Haskris
and we will advise you of precautions
and the proper procedures to follow.
4.1.5 Response Time for
Adjustments:
While each Haskris
system varies and individual design
specifications may call for rapid response
in temperature adjustment, owners of
systems with common configurations
should allow up to 15 minutes for any
temperature adjustments to take effect.
This is due to the thermal mass of the
system and the nature of the cooling
system.
4.1.6 Condensation Reminder:
If the
temperature setting is below the ambient
dew point the piping should be insulated to
prevent condensation. Setting temperature
below the dew point could also cause
condensation on the surfaces of the
equipment being cooled with resultant
damage. Consult a dew point chart to
calculate the dew point in your environment.
