Features/Benefits
Quality design and construction make the Evergreen
23XRV chillers the best
choice for modern, efficient
chilled water plants.
Product reliability
The 23XRV chiller uses proven technology from Carrier’s existing line of
Evergreen chillers along with innovations that increase reliability. The
23XRV compressors are designed for
extremely high reliability. The advanced tri-rotor compressor features a
balanced rotor geometry and shorter
screw lengths, resulting in vastly reduced compressor bearing loads and a
minimum L10 compressor bearing life
in excess of 500,000 hours when operated at AHRI conditions.
Features/Benefits (cont)
Variable speed capacity control eliminates slide valves, their associated losses, and their potential failure modes.
Component count (both rotating and
total) has been minimized assuring
maximum reliability under a wide
range of operating conditions.
High efficiency
Per AHRI 550/590, chillers operate at
design conditions less than one percent
of the time. As a result, superior part
load efficiency is required for today’s
chilled water applications. The Ever-
®
green
chiller efficiency by optimizing compressor operation. Electric power consumption drops dramatically when the
motor speed slows. The 23XRV screw
chiller delivers industry-leading integrated part load values (IPLV) in an extremely broad range of applications
and climates.
23XRV screw chiller maximizes
Environmental leader
Carrier has long been committed to
the environment and its sustainability.
The Evergreen 23XRV screw chillers
provide our customers with a highefficiency, chlorine-free, long-term
solution unaffected by refrigerant
phase outs. Carrier’s decision to utilize
non-ozone depleting HFC-134a refrigerant provides our customers with a
safe and environmentally sound
product without compromising efficiency. In addition, HFC-134a was
given an A1 safety rating by ASHRAE
(American Society of Heating,
Refrigerating and Air Conditioning
Engineers), meaning that it is the safest
refrigerant available.
Quality design
Positive displacement compression — Positive displacement com-
pression ensures stable operation
under all load conditions without the
possibility of compressor surge.
Superior oil management/cold
condenser water operation — All
Evergreen 23XRV chillers regulate oil
temperature, viscosity and pressure. A
patented process assures high quality
oil is delivered to the compressor bearings by a positive displacement pump.
Bearing lubrication is assured, allowing
continuous operation with cold
condenser water at all loads. Screw
chillers no longer need to rely on differential system pressure to effectively
lubricate the compressor. Should the
input power to the chiller be lost, the
system design assures proper lubrication of the bearings during coast down.
Small footprint — The Evergreen
23XRV chiller’s positive pressure
design reduces the chiller size by up
to 35% compared to negative-pressure
designs. Extremely high compression
efficiencies allow for compact,
high-efficiency chillers that require less
mechanical room floor space.
Constant or variable evaporator
flow — The 23XRV chiller combines
the advantages of positive displacement compression with variable speed
capacity control. This process provides
a chiller that reacts substantially better
than chillers equipped with inlet guide
vanes or slide valves. This allows for
easier transition when bringing additional chillers on line in multiple chiller
plants and eliminates any possibility of
surge, regardless of the changes in the
system.
Low harmonic distortion — The
Evergreen 23XRV chiller will generate
less than 5% total harmonic distortion
at the input to the VFD (variable
frequency drive) without the use of
any external filters or line reactors.
This assures the VFD alone cannot
exceed the IEEE-519 standard for
distortion at the point of common
coupling. Ultra-low harmonics can
eliminate the need for complicated
harmonic system studies.
Low starting current (inrush) —
The inrush current is limited to the
chiller full load amps (rated load
amperes). No other starting means can
equal this level of starting current. The
combination of low current and ultra
low harmonics can reduce backup
generator size requirements.
0.99 power factor — The Evergreen 23XRV chiller can operate at up
to 0.99 displacement power factor,
which helps building owners avoid
power factor penalties and decreases
electrical losses in cables and transformers. High power factor may also
reduce KVA requirements, saving electrical system costs on new projects or
freeing up electrical resources on existing systems operating near their maximum capacity.
Refrigerant-cooled VFD — Refrigerant cooling of the VFD minimizes
VFD size and ensures proper cooling
of the transistors for extended life.
Using R-134a refrigerant instead of
water also eliminates costly maintenance associated with the water cooling pump, heat exchanger and rubber
tubing used with water-cooled VFDs.
Optional seismic kit — A seismic
isolation package is available to meet
International Building Code and ASCE
7 seismic qualification requirements in
concurrence with ICC ES AC156 Acceptance Criteria for Seismic Qualification by Shake-Table Testing of Nonstructural Components and Systems.
Hermetic motor — The Evergreen
23XRV chiller utilizes motors that are
hermetically sealed from the machine
room. Cooling is accomplished by
spraying liquid refrigerant on the
motor windings. This highly efficient
motor cooling method results in coolerrunning motors than could be realized
with air-cooled designs of the same
type.
In addition, Carrier’s hermetic de-
sign eliminates:
• Compressor shaft seals that require
maintenance and increase the likelihood of refrigerant leaks.

• Machine room cooling requirements
associated with air-cooled motors,
which dissipate heat to the mechanical room.
• High noise levels common with aircooled motors, which radiate noise
to the machine room and adjacent
areas.
• Shaft alignment problems that occur
with open-drive designs during startup and operation, when equipment
temperature variations cause thermal expansion.
Positive pressure design — Positive pressure designs eliminate the
need for costly low pressure containment devices, reducing the initial cost
of the system. The Evergreen
®
23XRV
chiller’s positive pressure design ensures that air, moisture and other performance degrading contaminants are
not sucked inside the chiller. Purge
units and their associated maintenance are no longer necessary.
Optional refrigerant isolation
valves — The optional refrigerant
isolation valves allow the refrigerant
to be stored inside the chiller during
shipment from the factory, minimizing
start-up time. During servicing, the
“in-chiller” storage reduces refrigerant
loss and eliminates time-consuming
transfer procedures. As a self-contained
unit, the Evergreen 23XRV chiller does
not require additional remote storage
systems.
Optional pumpdown unit — Combined with the refrigerant isolation
valves listed above, the optional pumpdown unit eliminates complex connections to portable transfer systems,
thereby reducing service costs. The optional pumpdown compressor meets
Environmental Protection Agency’s
(EPA) vacuum level requirements that
mandate minimizing refrigerant emissions during service.
Modular construction — The cooler, condenser, and compressor assemblies are bolted together, making Evergreen 23XRV chillers ideally suited for
replacement jobs where ease of disassembly and reassembly at the jobsite
are essential.
Single point power — The 23XRV
chiller features internal control power
transformers to provide low voltage
power (115 v and 24 vdc) for machine
controls. Simply connecting the three
input power leads to the VFD provides
all unit power.
Marine container shipment — The
compact design allows for open-top
container shipment to export destinations, ensuring quality while reducing
shipping cost.
Heat exchanger combinations —
The Evergreen 23XRV chillers are
available with a complete line of heat
exchangers, ensuring the best combination of chiller components to meet
project specific tonnage and efficiency
requirements. One, 2 and 3-pass
arrangements are available to meet a
wide variety of flow conditions. Nozzlein-head and marine waterboxes are
available to meet 150 psig and
300 psig piping requirements.
Heat exchanger features
ASME certified construction — An
independent agency certifies the
design, manufacture, and testing of
all heat exchangers to American
Society of Mechanical Engineers
(ASME) standards, ensuring heat exchanger safety, reliability and long life.
The ASME U-stamp is applied to the
refrigerant side of the evaporator and
condenser and is applied to the water
side of heat exchangers when 300 psig
marine water boxes are provided.
High performance tubing — Carrier’s
Evergreen chillers utilize advances in heat
transfer technology, providing compact,
high-efficiency heat exchangers. Tubing
with advanced internally and externally
enhanced geometry improves chiller performance by reducing overall resistance
to heat transfer while reducing fouling.
Cooler tube expansion — Cooler
tube expansion at center support
sheets prevents unwanted tube movement and vibration, thereby reducing
the possibility of premature tube failure. Tube wall thickness is greater at
the expansion location, support sheets,
and end tube sheets in order to provide
maximum strength and long tube life.
Double-grooved end tube sheet
holes — This design provides a more
robust seal than single rolled joints, reducing the possibility of leaks between
the water and refrigerant sides of the
chiller.
Condenser baffle — The baffle deflects hot discharge gas before it contacts condenser tubes, reducing tube
vibration and wear while distributing
refrigerant more evenly over the
length of the vessel for improved
efficiency.
Closely spaced intermediate support sheets — Support sheets pre-
vent tube sagging and vibration, thereby increasing heat exchanger life.
Refrigerant filter isolation valves
— These valves allow filter replace-
ment without pumping down the chiller, reducing service time and expense.
FLASC (flash subcooler) — The
subcooler, located in the bottom of the
condenser, increases the refrigeration
effect by cooling the condensed liquid
refrigerant to a lower temperature,
thereby reducing compressor power
consumption.
AccuMeter™ system — The
AccuMeter system regulates refrigerant
flow according to load conditions,
providing a liquid seal at all operating
conditions, eliminating unintentional
hot gas bypass.
Microprocessor controls

feature also allows the machine to
operate at reduced capacity, rather
than shut down, when key safety limits
are approached.
Chilled liquid reset — Reset can be
accomplished manually or automatically from the building management system. For a given capacity, reset allows
operation at slower compressor
speeds, saving energy when warmer
chilled liquid can be used.
Demand limiting — This feature limits the power draw of the chiller during
peak loading conditions. When incorporated into the Carrier Comfort
Network
®
building automation system,
a red line command holds chillers at
their present capacity and prevents any
other chillers from starting. If a load
shed signal is received, the compressors are unloaded to avoid demand
charges whenever possible.
Ramp loading — Ramp loading ensures smooth pulldown of liquid loop
temperature and prevents a rapid
increase in compressor power consumption during the pulldown period.
Automated controls test — The
test can be executed prior to start-up
to verify that the entire control system
is functioning properly.
365-day real time clock — This
feature allows the operator to program
a yearly schedule for each week, weekends, and holidays.
Occupancy schedules — Schedules
can be programmed into the controller
to ensure that the chiller operates
when cooling is required and remains
off when not needed by the tenants or
process.
Extensive service menu — Unauthorized access to the service menu
can be prevented through password
protection. Built-in diagnostic capabilities assist in troubleshooting and recommend proper corrective action for
preset alarms, resulting in greater
working time.
Alarm file — This file maintains the
last 25 time-and date-stamped alarm
messages in memory. This function reduces troubleshooting time and cost.
Alert file — This file maintains the
last 25 alert messages in memory. This
function provides prognostic information and corrective actions that can
avoid unit shutdown.
Configuration data backup —
Non-volatile memory provides
protection during power failures and
eliminates time consuming control
reconfiguration.
