Features/Benefits (cont)Simple, reliable operation — The16TJ chiller’s single generator providesone stage of solution reconcentration,which makes the 16TJ chiller one ofthe most basic cycles currently available. The 16TJ chiller’s simple design,in addition to its other quality features,equates to inherently high reliability.Few moving parts and simple, dependable operation reduce downtime, aswell as service and maintenance costs.Exceptional efficiency — The 16TJchiller offers full-load steam rates of17.2 lb/hr-ton at standard ARI (AirConditioning and RefrigerationInstitute) operating conditions andleads the single-effect chiller market inefficiency. Incorporated into thestandard machine design is a solutionheat exchanger, intended to preheatthe weak lithium bromide solutionbeing pumped to the generator byprecooling the strong solution from thegenerator, as well as a second heatexchanger to further boost cycleefficiency by reclaiming additional heatfrom the steam condensate to furtherpreheat the weak solution.Superior part-load performance —The concentration control system of the16TJ chiller allows stable, part-loadoperation at cooling water temperatures as low as 64 F exclusive of theneed for a cooling tower bypass. A control valve integral to the machine guarantees stable, continuous refrigerantpump operation at part-load conditions.The 16TJ chiller has a continuousoperating range from 100% to 10% ofrated machine capacity.100 to 700 tons, make the 16TJsingle-effect absorption chiller the ultimate choice for comfort cooling and/or light industrial applications.Computerized performance ratings allow the appropriately sized machine tobe selected in order to meet exact jobrequirements. All machine selectionsare rated in accordance with ARIStandard 560-2000.Combine absorption and electricdriven chillers — Utilizing bothabsorption and electric chillers in acentral plant offers the flexibility tobase load one chiller, while using theother to handle peak load requirements. Hybrid chiller systems haveproven to be an economical solutionfor many chilled water plants. In manygeographical areas, operating theelectric chiller as the base loadedmachine while using the absorptionchiller during peak load conditionsprovides the most economical operating cost scenario. The reverse mayalso be true, depending on utility ratestructures and other job specifics.Either way, a 16TJ single-effectabsorption chiller used in conjunctionwith an electric-driven chiller may bethe most efficient and cost-effectivecombination available.Location and installationsavingsEase of installation — All machinesare completely fabricated, assembled,wired and tested in the factory as singlepiece units.

Microprocessor controlfeatures/benefitsEach 16TJ single-effect chiller includesa pre-programmed, factory-mountedand factory-wired control panel, whichis functionally tested prior to shipment.Chiller monitoring and control isautomatic and continuous, and thescreen on the front panel displayschiller operational status and faultindications in English or metric units.The Carrier-Sanyo microprocessorPID (proportional, integral, derivative)control system surpasses proportionalonly control systems by maintaining precise leaving chilled water temperatureversus actual set point. The PID controlssurpass proportional only controls intheir ability to control the machine andnarrow temperature variations. The16TJ chiller control system also incorporates the ability to control the chilledwater and cooling water pumps automatically. During shutdown thesepumps are sequenced to ensure a complete dilution cycle, thus providing protection from solution crystallization.Leaving chilled water temperature ismeasured every 5 seconds by the control system. Steam input to the generator is then adjusted according to thedegree of deviation of actual leavingchilled water temperature versus setpoint. System temperatures, set pointsand operational records are displayedon the front of the panel along withvarious indicator lights that representchiller operational status. A purgestatus light on the panel indicates whennoncondensables need to be exhaustedfrom the external purge storage chamber via the purge pump.The Carrier-Sanyo 16TJ chiller’scontrol system automatically performsself-diagnostic checks by constantlymonitoring the chiller’s operationalstatus and will automatically shut downthe machine if a fault occurs. Thecause of shut down will be retained inthe controller’s memory and can bedisplayed for immediate operatorreview. The controller’s memory willalso retain and display the cause ofthe last three system fault conditions,which is extremely useful for maintaining an accurate record of unit performance and fault history.Local or remote operation of the16TJ chiller can be done by configuration of the controls during initial setup.Single point electrical connection— Installation costs are reduced byeliminating the need for field wiring between machine components. All electrical items, including the unit-mountedpurge pump, are factory-wired to thechiller control center and require a single point electrical connection to themachine from the building’s electricalservice. A control power transformermounted in the chiller panel providessecondary single-phase control power.Low maintenanceDurable machine construction —Each Carrier-Sanyo 16TJ chiller isconstructed to meet rigorous manufacturing and design requirements in anISO-9002 and ISO-14001 certifiedfacility. Furthermore, every machinemeets strict Underwriters’ Laboratories(UL) certification requirements andis UL listed. The 16TJ chiller offersnumerous features as part of itsstandard design to provide dependableoperation. Corrosion-proof stainlesssteel dispersion trays ensure continuous, reliable operation, free fromblockage often characteristic ofalternative designs. The evaporator,absorber and condenser tubesheetsand waterboxes are epoxy painted toresist rust and corrosion. Also, everymachine is furnished with a rupturedisk to protect against an overpressurecondition on the shellside. Thesestandard design and constructionfeatures mean that every 16TJ singleeffect chiller is built to withstand themost rigorous duty, whether appliedfor comfort cooling service or lightprocess applications.Leakproof hermetic pumps withisolation valves cut maintenancecosts — The 16TJ chiller’s absorbentand refrigerant pump/motor assemblies have a leakproof, self-containedand hermetically sealed design. Thehermetic construction eliminates theneed for a separate, complicated,and possibly leakprone seal watersystem and auxiliary water piping,while providing leak tightness andlonger machine life. Specially designedbearings absorb both radial and axialthrusts to ensure correct fit at all times.Concerns about external contaminationare eliminated since the fluid beingpumped lubricates and cools the pumpand motor assemblies. In addition, boththe rotor and stator are separated by astainless steel liner that protects thewindings from the fluid being handled.Thermal overload switches are embedded in the stator as an additional safetyfeature. This feature protects againsthigh winding temperature. The pumpsare field serviceable and inspection isrecommended after 25,000 hours or3 years of continuous operation. Isolation valves, a standard feature on thesuction and discharge of the absorbentand refrigerant pumps, allow easy access for service and maintenance.Waterbox design simplifies maintenance procedures — Every 16TJchiller is provided with numerousstandard design features that permitconvenient and simple maintenanceto be carried out quickly. Hinged orremovable waterbox covers on theevaporator, absorber, and condenserfacilitate tube and waterbox inspectionand/or cleaning from either end of themachine. In addition, the absorber andcondenser sections are furnished asstandard with marine waterboxes foreasy access without having to disassemble water piping.Factory-trained service organization — In addition to routine maintenance and repair services, Carrier alsooffers a wide array of preventativemaintenance, full maintenance, and/orextended service contracts which canbe custom-tailored to fulfill any servicerequirements. Carrier’s extensiveservice organization offers trained andexperienced service technicians inevery major city.Superior corrosion protection —All absorption chillers must be protected from the corrosion that occurs oninternal machine surfaces when incontact with lithium bromide solution.The 16TJ absorption chiller includesan extremely effective corrosioninhibitor to provide an extra margin ofprotection against internal corrosion.Other inhibitors may need exotic tubematerials in certain heat exchangers asthey are less effective and require morefrequent maintenance and analysis.The superior corrosion protection ofthe Carrier-Sanyo inhibitor allowsthe use of standard copper tubesthroughout the machine (except forsteam generator tubes, which are90/10 cupronickel), which results inlong machine life and dependableoperation.3
Features/Benefits (cont)Automatic purge extendsmachine life, ensures optimumefficiency and performanceThe purge system on an absorptionchiller is essential to ensuring longmachine life and efficient operation.All absorption chillers operate in avacuum and generate hydrogen (andother noncondensable gases) in smallquantities, even when they are vacuumtight and properly inhibited. If notproperly controlled, these gases caninterfere with machine operation,therefore it is imperative that they beremoved to protect against internalcorrosion, lithium bromide solutioncrystallization, and/or reduction ofchiller capacity. The Carrier-Sanyopurge system protects against thesepotential hazards by operating continuously during machine operation.How the purge system operates —During chiller operation, any noncondensables that are present tend toaccumulate in the absorber section,which operates at the lowest pressureinternal to the machine. A slipstreamof lithium bromide solution flowsthrough an eductor from the absorbentpump discharge. This process createssuction, which draws the noncondensables from the absorber, entrainingthem with the solution flowing throughthe eductor. The eductor discharges thesolution and noncondensables into thepurge tank, where the noncondensables are separated from the solution.The noncondensables remain in thepurge tank while the lithium bromidesolution returns to the absorber sump.As noncondensables accumulate in theexternal purge tank, they are isolatedfrom the chiller and cannot re-enter thechiller even during shutdown. A heatedpalladium cell connected to the storagechamber aids in elimination of hydrogen from the purge tank at all times. Aunit-mounted purge pump further aids4in removing noncondensables from thepurge tank, when necessary.Anticrystallization controls maintain proper solution concentration— The 16TJ chiller automatically limitssolution concentration in several ways toavoid both crystallization and overdilution to provide dependable, trouble-freeoperation. Crystallization of the lithiumbromide solution depends on the combination of temperature and concentration. The Carrier-Sanyo concentrationcontrol system automatically monitorssolution concentration by continuouslysensing the temperature of the strongsolution and the refrigerant condensation temperature. From this data, themicroprocessor controls are able todetermine the solution concentrationand automatically limit the heat input tothe chiller, if necessary, to prevent anoverconcentration condition fromoccurring. Constant monitoring of thecycle ensures continuous, reliable operation even at cooling water temperaturesas low as 64 F. Upon shutdown, thechiller dilution cycle is automatically controlled to an optimized period rangingfrom 6 to 15 minutes by the microprocessor controls in conjunction with thegenerator solution temperature. Thisoptimized dilution operation period enables energy savings of the onboardchiller pumps as well as the chilled waterand cooling water pumps. The dilutioncycle also minimizes the time requiredfor chiller start-up by preventingoverdilution of the solution.16TJ single-effect absorptioncooling cycleThe 16TJ single-effect absorption chilleris comprised of an evaporator,absorber, condenser, steam generator,solution heat exchanger, steam drainreclaimer, refrigerant/absorbent pumps,purge, controls, and auxiliaries. Water isused as the refrigerant in vessels maintained under low absolute pressure(vacuum).The chiller operates on the principlethat under vacuum, water boils at a lowtemperature (approximately 40 F),thereby cooling the chilled watercirculating through the tubes of theevaporator. A refrigerant pump is usedto circulate the refrigerant water overthe evaporator tubes to enhance theheat transfer process. The refrigerantvapor is removed as it is produced inorder to make the cooling processcontinuous. A lithium bromide solution(which has a high affinity for water)is used to absorb the water vapor. Asthis process continues, the lithiumbromide becomes diluted, whichreduces its absorption ability. Anabsorbent pump then transfers thisweak (diluted) solution to the generator, where it is reconcentrated by theintroduction of low-pressure steam inthe tubes of the generator to boil offthe previously absorbed water. Thewater vapor released on the shellsideof the generator enters the condenserto be cooled and returned to a liquidstate. At this point, the refrigerantwater returns to the evaporator tobegin a new cycle. To remove heatfrom the machine, relatively cool waterfrom a cooling tower or other source iscirculated through the tubes of theabsorber to remove the heat ofvaporization. This same water is thencirculated through the tubes of thecondenser. The strong (reconcentrated)solution from the generator flows backto the absorber to begin a new cycle.For efficiency, the strong solutionfrom the generator is passed through asolution heat exchanger to preheat theweak solution while precooling thestrong solution before returning to theabsorber. The steam drain reclaimeralso improves cycle efficiency by transferring heat from the steam condensate to the weak solution.
