CHILLER FAMILIARIZATION
(Fig. 1 and 2)
Chiller Information Plate —
The information plate is
located on the right side of the chiller control panel.
System Components — The components include the
cooler and condenser heat exchangers in separate vessels,
motor-compressor, lubrication package, control panel, and
motor starter. All connections from pressure vessels have ex-
ternal threads to enable each component to be pressure tested
with a threaded pipe cap during factory assembly.
Cooler — This vessel (also known as the evaporator) is
located underneath the compressor. The cooler is main-
tained at lower temperature/pressure so evaporating refrig-
erant can remove heat from water flowing through its inter-
nal tubes.
Condenser — The condenser operates at a higher
temperature/pressure than the cooler and has water flowing
through its internal tubes in order to remove heat from the
refrigerant.
Motor-Compressor — This component maintains sys-
tem temperature and pressure differences and moves the heat-
carrying refrigerant from the cooler to the condenser.
Control Panel — The control panel is the user interface
for controlling the chiller. It regulates the chiller’s capacity
as required to maintain proper leaving chilled water tem-
perature. The control panel:
• registers cooler, condenser, and lubricating system
pressures
• shows chiller operating condition and alarm shutdown
conditions
• records the total chiller operating hours
• sequences chiller start, stop, and recycle under micro-
processor control
• displays status of motor starter
• provides access to other CCN (Carrier Comfort Network)
devices
