The Series R®

Helical Rotary

Screw Compressor• Unequaled Reliability. The next

generation Trane helical rotaryscrew compressor is designed,built and tested to the samedemanding and rugged standardsas the Trane scroll compressors,the centrifugal compressors, andthe previous generation helicalrotary screw compressors used inboth air and water cooled chillersfor more than 13 years.

• Years of research and testing. TheTrane helical rotary screwcompressor has amassedthousands of hours of testing,much of it at severe operatingconditions beyond normalcommercial air conditioningapplications.

• Proven track record. The TraneCompany is the world's largestmanufacturer of large helical rotarycompressors used for refrigeration.Over 90,000 compressorsworldwide have proven that theTrane helical rotary screwcompressor has a reliability rate ofgreater than 99.5 percent in thefirst year of operation - unequalledin the industry.

• Resistance to liquid slugging. Therobust design of the Series R

compressor can ingest amounts ofliquid refrigerant that wouldseverely damage reciprocatingcompressor valves, piston rods andcylinders.

• Fewer moving parts. The helicalrotary screw compressor has onlytwo rotating parts: the male rotorand the female rotor. Unlikereciprocating compressors, theTrane helical rotary screwcompressor has no pistons,connecting rods, suction anddischarge valves or mechanical oilpump. In fact, a typicalreciprocating compressor has15 times as many critical parts asthe Series R compressor. Fewermoving parts lead to increasedreliability and longer life.

• Direct-drive, low speed, semi-hermetic compressor for highefficiency and high reliability.

• Field serviceable compressor foreasy maintenance.

• Suction gas-cooled motor. Themotor operates at lowertemperatures for longer motor life.

• Five minute start-to-start/twominute stop-to-start anti-recycletimer allows for closer water looptemperature control.

Improved Operating

CapabilitiesLarger Capacity Range

The Series R Model RTAD includeeight sizes available in standard orhigh efficiency versions covering atotal capacity range from 250 to 650 kW. The efficient RTAC air-cooledhelical-rotary chillers are availablefor larger capacity up to 1500kW.

High Ambient Operation Capability

The High Ambient Series R ModelRTAD have been designed foroperation at 46°C at full load, someunits can also operate at 49°C at fullload using 915 rpm ZephyrWingfans. The former RTAB were using1410 rpm fans were generatinghigher sound levels requiring on siteadditional and costly soundtreatments, the RTAD will then be theideal solution for applications havingsound restrictions.

Improved Acoustical Performance

The sound levels of the Series RModel RTAB have been steadilyimproved since its introduction withthe different options to reduce thesound level. With the advent of theModel RTAD, sound levels arereduced significantly with the newcompressor specifically designed tominimize sound generation.

Superior Efficiency levels - the bar

has been raised

The High Efficiency Trane ModelRTAD has COP levels better than theprevious RTAB and also better COPlevels than conventionalreciprocating chillers operating withblends of refrigerant. The modern technology of the RTADwith the efficient direct-drivecompressor, the electronic expansionvalve and the UCM-CLDMicroprocessor Adaptive Control®

has permitted Trane to achieve theseefficiency levels.• Precise Rotor Tip Clearances.

Higher energy efficiency in a helicalrotary screw compressor is

obtained by reducing the rotor tipclearances. This next generationcompressor is no exception. Withtoday's advanced manufacturingtechnology, clearances can becontrolled to even tightertolerances. This reduces theleakage between high and lowpressure cavities duringcompression, allowing for moreefficient compressor operation.

• Capacity Control and LoadMatching. The combinationpatented unloading system onTrane helical rotary screwcompressor utilizes the variableunloading valve for the majority ofthe unloading function. This allowsthe compressor to modulateinfinitely to exactly match buildingload and to maintain chilled watersupply temperatures within ± 0.3°Cof setpoint. Reciprocating andscrew chillers that rely on steppedcapacity control must run at acapacity equal to or greater thanthe load and typically can onlymaintain water temperature toaround ± 1°C. Much of this excesscapacity is lost becauseovercooling goes toward buildinglatent heat removal, causing thebuilding to be dried beyond normalcomfort requirements. When theload becomes very low, thecompressor also uses a stepunloader valve which is a singleunloading step to achieve theminimum unloading point of thecompressor. The result of thisdesign is optimized part-loadperformance far superior to singlereciprocating compressors andstep-only screw compressors.

Simple Installation• Factory Testing Means Trouble-Free

Start-Up. All air-cooled Series Rchillers are given a completefunctional test at the factory. Thiscomputer-based test programcompletely checks the sensors,wiring, electrical components,microprocessor function,

communication capability,expansion valve performance andfans. In addition, each compressoris run tested to verify capacity andefficiency. Where applicable, eachunit is factory preset to thecustomer's design conditions, anexample would be leaving liquidtemperature set point. The endresult of this test program is thatthe chiller arrives at the job sitefully tested and ready foroperation.

• Factory-Installed and -TestedControls/Options SpeedInstallation. All Series R chilleroptions, including main powersupply disconnect, low ambientcontrol, ambient temperaturesensor, low ambient lockout,communication interface and icemaking controls are factoryinstalled and tested.

Module System Options - Ice Storage

Trane air-cooled chillers are wellsuited for ice production. The uniqueability to operate at decreasedambient temperature whileproducing ice lends to roughly thesame work seen by the compressor.An air-cooled machine typicallyswitches to ice production at night.Two things happen under thisassumption. First, the leaving brinetemperature from the evaporator islowered to around -5.5 to -5°C.Second, the ambient temperaturehas typically dropped about 8.3 to11°C from the peak daytime ambient.This effectively places a lift on thecompressors that is similar todaytime running conditions. Thechiller can operate in lower ambientat night and successfully produce iceto supplement the next day's coolingdemands.The Model RTAD produces ice bysupplying ice storage tanks with a

constant supply of glycol solution. Air-cooled chillers selected for theselower leaving fluid temperatures arealso selected for efficient productionof chilled fluid at nominal comfortcooling conditions. The ability of Tranechillers to serve "double duty" in iceproduction and comfort coolinggreatly reduces the capital cost of icestorage systems.When cooling is required, ice chilledglycol is pumped from the ice storagetanks directly to the cooling coils. Noexpensive heat exchanger is required.The glycol loop is a sealed system,eliminating expensive annualchemical treatment costs. The air-cooled chiller is also available forcomfort cooling duty at nominalcooling conditions and efficiencies.The modular concept of glycol icestorage systems and the provensimplicity of Trane Tracer™ controlsallow the successful blend ofreliability and energy savingperformance in any ice storageapplication.The ice storage system is operated insix different modes: each optimizedfor the utility cost of the hour.1. Provide comfort cooling with

chiller2. Provide comfort cooling with ice3. Provide comfort cooling with ice

and chiller4. Freeze ice storage5. Freeze ice storage when comfort

cooling is required6. OffTracer optimization software controlsoperation of the required equipmentand accessories to easily transitionfrom one mode of operation toanother. For example:Even with ice storage systems thereare numerous hours when ice isneither produced nor consumed, butsaved. In this mode the chiller is thesole source of cooling. For example,to cool the building after all ice isproduced but before high electricaldemand charges take effect, Tracersets the air-cooled chiller leavingfluid set point to its most efficientsetting and starts the chiller, chiller

pump, and load pump.When electrical demand is high, theice pump is started and the chiller iseither demand limited or shut downcompletely. Tracer controls have theintelligence to optimally balance thecontribution of ice and chiller inmeeting the cooling load.The capacity of the chiller plant isextended by operating the chiller andice in tandem. Tracer rations the ice,augmenting chiller capacity whilereducing cooling costs. When ice isproduced, Tracer will lower the air-cooled chiller leaving fluid set pointand start the chiller, ice and chillerpumps, and other accessories. Anyincidental loads that persists whileproducing ice can be addressed bystarting the load pump and drawingspent cooling fluid from the icestorage tanks.

Certain application constraintsshould be considered when sizing,selecting and installing Trane air-cooled Series R chillers. Unit andsystem reliability is often dependentupon properly and completelycomplying with theseconsiderations. When theapplication varies from theguidelines presented, it should bereviewed with your local Trane salesengineer.

Unit Sizing

Intentionally over-sizing a unit toassure adequate capacity is notrecommended. Erratic systemoperation and excessivecompressor cycling are often adirect result of an over-sized chiller.In addition, an oversized unit isusually more expensive to purchase,install, and operate. If over-sizing isdesired, consider using two units.

Water Treatment

Dirt, scale, products of corrosionand other foreign material willadversely affect heat transferbetween the water and systemcomponents. Foreign matter in thechilled water system can alsoincrease pressure drop and,consequently, reduce water flow.Proper water treatment must bedetermined locally, depending onthe type of system and local watercharacteristics. Neither salt norbrackish water is recommended foruse in Trane air-cooled Series Rchillers. Use of either will lead to ashortened life to an indeterminabledegree. The Trane Companyencourages the employment of areputable water treatment specialist,familiar with local water conditions,to assist in this determination and inthe establishment of a proper watertreatment program.

Effect Of Altitude on Capacity

At elevations substantially abovesea level, the decreased air densitywill reduce condenser capacity and,

therefore, unit capacity andefficiency.

Ambient Limitations

Trane air-cooled Series R chillers aredesigned for year-round operationover a range of ambienttemperatures. The air-cooled ModelRTAD chiller will operate in ambienttemperatures of 7 to 40 °C.Selecting the high ambient optionwill allow the chiller to operate inambient temperatures above 40 °Cand selecting the low ambientoption will increase the operationalcapability of the water chiller toambient temperatures as low as -18 °C. For operation outside ofthese ranges, contact the local Tranesales office.

Water Flow Limits

The minimum water flow rates aregiven in this catalog. Evaporatorflow rates below the tabulatedvalues will result in laminar flowcausing freeze-up problems, scaling,stratification and poor control. Themaximum evaporator water flowrate is also given in the general datasection. Flow rates exceeding thoselisted may result in excessive tubeerosion. The evaporator can withstand up to50 percent water flow reduction as

long as this flow is equal or abovethe minimum flow rate requirement.The microprocessor and capacitycontrol algorithms are designed totake a minimum of 10% change inwater flow rate per minute.

Flow Rates out of Range

Many process cooling jobs requireflow rates that cannot be met withthe minimum and maximumpublished values within the ModelRTAD evaporator. A simple pipingchange can alleviate this problem.For example: A plastic injectionmolding process requires 5.1 l/s of10°C water and returns that water at15.6°C. The selected chiller canoperate at these temperatures, buthas a minimum flow rate of 7.6 l/s.The following system can satisfy theprocess.

1. Load2. 15.6°C - 5 L/s3. Chilled water pump - 7.5 L/s4. 13.7°C - 7.6 L/s

5. 10°C - 7.6 L/s6. 10°C - 5 L/s7. Chilled water pump - 5 L/s8. 10°C - 2.5 L/s

Leaving Water Temperature Range.

Trane air-cooled Series R chillershave three distinct leaving watercategories: standard, lowtemperature, and ice making. Thestandard leaving solutiontemperature range is 4.4 to 15.6 °C.Low temperature machines produceleaving liquid temperatures lessthan 4.4 °C. Since liquid supplytemperature setpoints less than 4 .4 °C result in suctiontemperatures at or below thefreezing point of water, a glycolsolution is required for all lowtemperature machines. Ice makingmachines have a leaving liquidtemperature range of -6.7 to 15.6°C. Ice making controls include dualset point controls and safeties forice making and standard coolingcapabilities. Consult your local Tranesales engineer for applications orselections involving lowtemperature or ice makingmachines. The maximum watertemperature that can be circulatedthrough an evaporator when theunit is not operating is 42 °C .

Leaving Water Temperature out of

Range

Similar to the flow rates above,many process cooling jobs requiretemperature ranges that cannot bemet with the minimum andmaximum published values for theModel RTAD evaporator. A simplepiping change can alleviate thisproblem. For example: A laboratoryload requires 7.6 l/s of waterentering the process at 29.4°C andreturning at 35°C. The accuracyrequired is better than cooling towercan give. The selected chiller hasadequate capacity, but a maximumleaving chilled water temperature of15°C.

In the example shown, both thechiller and process flow rates areequal. This is not necessary. Forexample, if the chiller had a higherflow rate, there would simply bemore water bypassing and mixingwith warm water.

Supply Water Temperature Drop

The performance data for the Traneair-cooled Series R chiller is basedon a chilled water temperature dropof 5°C. Chilled water temperature

drops from 3.3 to 10 °C may be usedas long as minimum and maximumwater temperature and minimumand maximum flow rates are notviolated. Temperature drops outsidethis range are beyond the optimumrange for control and may adverselyaffect the microcomputer's ability tomaintain an acceptable supply watertemperature range. Furthermore,temperature drops of less than 3.3°C may result in inadequaterefrigerant superheat. Sufficientsuperheat is always a primaryconcern in any direct expansionrefrigerant system and is especiallyimportant in a package chiller wherethe evaporator is closely coupled tothe compressor. When temperaturedrops are less than 3.3 °C, anevaporator runaround loop may berequired.

Ice Storage Provides Reduced

Electrical Demand

An ice storage system uses astandard chiller to make ice at nightwhen utilities charge less forelectricity. The ice supplements oreven replaces mechanical coolingduring the day when utility rates areat their highest. This reduced needfor cooling results in big utility costsavings.Another advantage of ice storage isstandby cooling capacity. If thechiller is unable to operate, one ortwo days of ice may still be availableto provide cooling. In that time thechiller can be repaired beforebuilding occupants feel any loss ofcomfort.The Trane Model RTAD chiller isuniquely suited to low temperatureapplications like ice storage becauseof the ambient relief experienced atnight. This allows the Model RTADchiller to produce ice efficiently, withless stress on the machine.Simple and smart control strategiesare another advantage the ModelRTAD chiller offers for ice storageapplications. Trane Tracer® buildingmanagement systems can actuallyanticipate how much ice needs to be

Figure 3 - If temperatures are out of range for equipment

made at night and operate thesystem accordingly. The controls areintegrated right into the chiller. Twowires and preprogrammed softwaredramatically reduce field installationcost and complex programming.

Short Water Loops

The proper location of thetemperature control sensor is in thesupply (outlet) water connection orpipe. This location allows thebuilding to act as a buffer andassures a slowly changing returnwater temperature. If there is not asufficient volume of water in thesystem to provide an adequatebuffer, temperature control can belost, resulting in erratic systemoperation and excessivecompressor cycling. A short waterloop has the same effect asattempting to control from thebuilding return water. Typically, atwo-minute water loop is sufficientto prevent a short water loop.Therefore, as a guideline, ensure thevolume of water in the evaporatorloop equals or exceeds two timesthe evaporator flow rate. For arapidly changing load profile, theamount of volume should beincreased. To prevent the effect of ashort water loop, the followingitems should be given carefulconsideration: A storage tank orlarger header pipe to increase thevolume of water in the system and,therefore, reduce the rate of changeof the return water temperature.

Controls

Chiller Unit Controls Trouble-Free Installation, Start-Up

and Operation

Adaptive Control means the UnitControl Module (UCM-CLD) directlysenses the control variables thatgovern operation of the chiller:motor current draw, evaporatortemperature, condensertemperature, etc. When any of thevariables approaches a limitcondition where the unit may bedamaged or shut down on a safety,the UCM takes corrective action toavoid shutdown and keep the chilleroperating. It does this throughcombined actions of compressorslide valve modulation, electronicexpansion valve modulation and fanstaging.Additionally, the UCM optimizestotal unit power consumptionduring normal operating conditions.

No other chiller control system inthe marketplace duplicates thisperformance.

Safety Controls

A centralized microcomputer offersa higher level of machine protection.Since the safety controls aresmarter,they limit compressor operation toavoid compressor or evaporatorfailures, thereby minimizingnuisance shutdown. Duringabnormal operating conditions, theUCM will continue to optimizechiller performance by taking thecorrective action necessary to avoidshutdown.This keeps cooling capacityavailable until the problem can besolved. Whenever possible, thechiller is allowed to perform itsfunction; make chilled water. In

addition, microcomputer controlsallow for more types of protectionsuch as over and under voltage!Overall, the safety controls helpkeep the building running and out oftrouble.

The End Of Nuisance Trip-Outs And

Unnecessary Service Calls

Unnecessary service calls andunhappy tenants are avoided. Theunit does not nuisance trip orunnecessarily shut down. Onlywhen the UCM has exhausted thecorrective actions it can take and theunit is still violating an operatinglimit will the unit shut down.CONTROLS ON OTHER CHILLERSTYPICALLY SHUT DOWN THECHILLER, QUITE PROBABLY JUSTWHEN IT IS NEEDED THE MOST.For example:

A typical five-year-old chiller withdirty coils might trip-out on highpressure cutout on a 38°C day inAugust. A hot day is just whencomfort cooling is needed the most.In contrast, the air-cooled Series Rchiller with an Adaptive Controlmicroprocessor will stage fans on,modulate electronic expansionvalve, and modulate slide valve as itapproaches a high pressure cutout.Thereby KEEPING THE CHILLER ON-LINE JUST WHEN YOU NEED IT THEMOST.

Generic Building

Automation System

ControlsSimple Interface With Other Control

Systems

Microcomputer controls affordsimple interface with other controlsystems, such as time clocks,building automation systems andice storage systems. Wiring to theunit can be as simple as two wires!This means you can have theflexibility to meet job requirementswhile not having to learn acomplicated control system.

Monitoring And Diagnostics

Since the microcomputer providesall control functions, it can easilyindicate such parameters as leavingchilled water temperature andcapacity stage. If a failure doesoccur, one of over 90 individualdiagnostic and operating codes willbe used to indicate the problem,giving more specific informationabout the failure. All of themonitoring and diagnosticinformation is displayed directly ona microcomputer display.

Interface With The Trane Integrated

Comfort™ System (ICS)

When the air-cooled Series R® chilleris used in conjunction with a TraneTracer® system, the unit can bemonitored and controlled from aremote location. The air-cooledSeries R chiller can be controlled tofit into the overall buildingautomation strategy by using timeof day scheduling, timed override,duty cycling, demand limiting, andchiller sequencing. A building ownercan completely monitor the air-cooled Series R chiller from theTracer system, as all of themonitoring information indicated onthe microcomputer can be read offthe Tracer system display. Inaddition, all the powerful diagnosticinformation can be read back at theTracer system. Best of all, thispowerful capability comes over asingle twisted pair of wires! Air-cooled Series R chillers caninterface with many differentexternal control systems, fromsimple stand- alone units to icemaking systems. Each unit requiresa single-source, three-phase powersupply, a 115-volt control powertransformer handles both theevaporator heat tape and the unitcontrols. The control transformer isdirectly fed from the 400/3/50 supplyin the control panel. For basic stand-alone applications, the interfacewith outside control is no differentthan for other Trane chillers.However, the RTAD units have many

features that can be used tointerface with building controlsystems.

Standard Features:External Auto/Stop

A job site provided contact closurewill turn the unit on and off.Note: Do not use the chilled waterpump to stop the chiller.

Chilled Water flow Interlock

A job site provided contact closurefrom a chilled water pump contactoror a flow switch is required and willallow unit operation if a load exists.This feature will allow the unit torun in conjunction with the pumpsystem.

External Interlock

A job site supplied contact openingwired to this input will turn the unitoff and require a manual reset of theunit microcomputer. This closure istypically triggered by a job sitesupplied system such as a firealarm.

Chilled Water Pump Control

Unit controls provide an output tocontrol chilled water pump(s). Onecontact closure to the chiller is allthat is required to initiate the chilledwater system.

Remote Running and Alarm

Indication Contacts

The unit provides three single-pole/double-throw contact closuresto indicate that a failure hasoccurred, if any compressors arerunning, or if the compressors arerunning at maximum capacity. Thesecontact closures may be used totrigger job site supplied alarm lightsor alarm bells.

Optional Features:Communication Interface (CSR

Three-phasecondenser fans motors withpermanently lubricated ball bearingare provided. Standard units will

start and operate between of 4°C (39F) to the maximum possibleambient of the selected unit.

Compressor and Lube Oil System

The rotary screw compressor issemi-hermetic, direct drive, 3000rpm, with capacity control slidevalve, a load/unload valve, rollingelement bearings, differentialrefrigerant pressure oil pump, oilfilter and oil heater. The motor is asuction gas cooled, hermeticallysealed, two-pole squirrel cageinduction motor. Oil separatordevices are provided separate fromthe compressor. Check valves in thecompressor discharge and lube oilsystem are provided.

Refrigeration Circuits

Each unit has two refrigerantcircuits, with one rotary screwcompressor per circuit. Eachrefrigerant circuit includes a liquidline shutoff valve, removable corefilter drier, charging port and anelectronic expansion valve. Fullymodulating compressors andelectronic expansion valves providevariable capacity modulation overthe entire operating range.

Unit Controls

All unit controls are housed in aweather-tight enclosure with hingeddoors to allow for customerconnection of power wiring andremote interlocks.All controls, including sensors, arefactory mounted and tested prior toshipment. All cataloged unitscomply to EN 60204 and are EMCcompatible.Microcomputer controls provide allcontrol functions including start-upand shut down, leaving chilled watertemperature control, compressorand electronic expansion valvemodulation, fan sequencing, anti-recycle logic, automatic lead/lagcompressor starting and loadlimiting.

The unit control module, utilizingAdaptive Control™ microprocessor,automatically takes action to avoidunit shutdown due to abnormaloperating conditions associatedwith low refrigerant temperature,high condensing temperature andmotor current overload. Should theabnormal operating conditioncontinue until a protective limit isviolated, the unit will be shut down.Unit protective functions includeloss of chilled water flow,evaporator freezing, loss ofrefrigerant, low refrigerant pressure,high refrigerant pressure, reverserotation, compressor starting andrunning over current, phase loss,phase imbalance, phase reversal,and loss of oil flow.A menu driven digital displayindicates over 20 operating datapoints including chilled water setpoint, current limit Set point, leavingchilled water temperature,evaporator and condenserrefrigerant pressures andtemperatures. Over 60 diagnosticchecks are made and displayedwhen a problem is detected. Thedigital display can be read andadvanced on the unit withoutopening any control panel doors.Standard power connectionsinclude main three phase power andtwo 115 volt single phase powerconnections for control power andheat tape.

Starters

Starters are housed in aweathertight enclosure withremovable cover plate to allow forcustomer connection of powerwiring. Wye Delta closed transition startersare standard on all RTAD units.
