System Components — The components include the

cooler and condenser heat exchangers in separate vessels,

compressor-motor, lubrication package, control panel, and

VFD. 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

located underneath the compressor. The cooler is maintained at

lower temperature/pressure so evaporating refrigerant can

remove 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-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 temperature.

The control panel:

• registers cooler, condenser, and lubricating system pressures

• shows the chiller operating condition and the alarm

shutdown conditions

• records the total chiller operating hours

• sequences chiller start, stop, and recycle under microproces-

sor control

• displays the status of the VFD

• provides access to other CCN (Carrier Comfort Network

)

devices and energy management systems

• languages pre-installed at factory include: English, Chinese,

Japanese, and Korean.

• International Language Translator (ILT) is available for

conversion of extended ASCII characters.

Variable Frequency Drive (VFD) — The VFD al-

lows for the proper start and disconnect of electrical energy for

the compressor-motor, oil pump, oil heater, and control panel.

Storage Vessel (Optional) — There are 2 sizes of

storage vessels available. The vessels have double relief valves,

a magnetically-coupled dial-type refrigerant level gage, a

one-inch FPT drain valve, and a

-in. male flare vapor con-

nection for the pumpout unit.

NOTE: If a storage vessel is not used at the jobsite, factory-

installed isolation valves on the chiller may be used to isolate

the chiller charge in either the cooler or condenser. An optional

pumpout system is used to transfer refrigerant from vessel to

vessel.
