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 features
Direct Digital Product Integrated control (PIC III) — Carrier’s PIC III
provides unmatched flexibility and functionality. Each unit integrates directly with the Carrier Comfort Network solution to controls applications.
International Chiller Visual Con­troller (ICVC) — The ICVC provides
an unparalleled ease of operation and can be configured to display English or metric values.

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.
