CHILLER FAMILIARIZATION

(Fig. 1 and 2)

Chiller Information Nameplate — The information nameplate 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 mo- tor starter. All connections from pressure vessels have external 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 lo- cated underneath the compressor. The cooler is maintained at lower temperature/pressure so evaporating refrigerant can re- move heat from water flowing through its internal 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-CompressorThis 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 temperature. 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 micropro- cessor control

displays status of motor starter

provides access to other CCN (Carrier Comfort Net- work) devices and energy management systems

Languages pre-installed at factory include: English, Chi- nese, Japanese, and Korean (ICVC only).

International language translator (ILT) is available for conversion of extended ASCII characters (ICVC only).
