IntroductionHybrid Chiller PlantA chiller plant design that allows theoperator to choose betweenmultiple energy sources is referredto as a hybrid design. Hybrid chillerplants are receiving increasingattention as valuable options forfacility owners. There are varioustypes of hybrid plant designs. Theyencompass different combinationsof electric chillers and other chillertypes, including gas or steamabsorption chillers. The advantagesof having a choice of energy sourceswill become even more viable as wemove further into the newmillennium. 2001 American Standard Inc. All rights reserved.Today we hear about utilityderegulation. For the first time,building owners can negotiatepower supply and natural gascontracts with their traditionalsupplier, as well as with newsuppliers in the market. The fuelswitching flexibility of the hybridplant puts the owner in a muchstronger negotiating position.Similarly, many electric utilities offerattractive off-peak or dual fuelelectric rates for applications whichare not operating during peakelectric system demand, mostcommonly in the summer months.This represents an opportunity forbuilding owners who can switch to agas or steam system.ABS-PRC001-E4

Features andBenefitsGeneralTrane Horizon AbsorptionSeries, Single-Stage HotWater- or Steam-FiredAbsorption Water Chillers,500-1350 TonsTechnology You Can TrustIn the early 1990’s, with theassistance of the Gas ResearchInstitute, Trane began developing aninnovative series of absorptionchillers. In 1995, Horizon chillersbegan shipping from the Tranemanufacturing facility in La Crosse,Wisconsin. The Horizon chiller is soadvanced, it redefined industrystandards for absorption systemintegrity. Horizon chillerperformance, efficiency andreliability far exceed that of past andpresent absorption chillers.Dynamic By DesignBecause uninterrupted chillerservice is critical to your operation,Horizon chillers are designed tomake chilled water reliably, even inthe harshest industrial application.Water-tower systems and loadrequirements can challenge thelong-term operation of manystandard-grade chillers. Theindustrial-grade construction of theHorizon chillers accounts for varyingload and water-temperaturechanges, as well as dirty towerwater. They are built with corrosiveresistant alloy metals, and precisionwelded in an ISO 9001 qualitycertified facility. Only extended-lifepumps, valves and water boxes aremanufactured into their design. Forfurther dynamics, Horizon UCP2adaptive microprocessor controlsreact precisely to systemdiversification. Quality construction,long-life components and adaptivecontrols are what make the Horizondynamic by design.4ABS-PRC001-E4
Features andBenefitsGeneralOperates With Energy-Saving, LowPressure Steam or Hot WaterExpanded, the Horizon familyincludes a single-stage, hot wateror steam-fired chiller line. Able toproduce chilled water in the rangeof 40 to 60ºF (4.4 to15.6ºC), thesemachines use 12 psig (0.83 bar) lowgrade steam or 270ºF (132ºC) hotwater.Making chilled water from thesecomparatively low-temperatureinputs is particularly important forenergy conserving applications,such as waste-heat recovery, cogeneration equipment and solarenergy-powered cooling.Using refrigerant water helpseliminate refrigerant managementor availability concerns.Additionally, absorption technologyreduces the use of electric energy.ABS-PRC001-E45
Features andBenefitsSophisticated ReliabilityHorizon controls meet specificationsfor stand alone or hybrid chillercontrol. UCP2 adaptive controls arecritical to reliable operation. Tranecontrols are compatible withIntegrated Comfort Systems (ICS),and are easily integrated into theTracer family of flexible chillerplant system controllers with asingle twisted-pair communicationscable.Ideal for Process and CommercialApplicationsWith Horizon chillers, theapplication possibilities for theabsorption machine are expanded.Capabilities such as lower towerflow, variable evaporator flow, lowerchilled-water temperatures andadvanced control capabilities makethe single-stage Horizon absorptionchiller ideal for both process andcomfort applications.When Long-lived Reliability IsImportantTrane has been a long-timeproponent of the use of high-qualitymaterials in absorption chillerdesigns. The lithium bromidetemperatures and water refrigerant,typical of all absorbers, can morequickly corrode lower-grade metalsin the presence of air. Tranerecommends and uses industrialgrade materials to provide longlived, reliable cooling.6A Global Network of AbsorptionExpertiseWhen you specify a Trane Horizonchiller, you’re getting theknowledge, expertise and assistanceof a pool of experts that havedecades of absorption expertise.Making The Trane Company part ofyour management team gives youaccess to refrigeration, airconditioning and facility controlsystem applications specialists, anda unique breadth of innovativesolutions to satisfy your facilitiesneeds for today and tomorrow.Standard Specification For SingleStage Horizon Chillers C.O.P. 0.70 Victaulic water connections Fully-automatic purge system Industrial-grade tubes— Generator .028” wall, 90/10Cupro-nickel— Evaporator .025” wall copper(enhanced)— Absorber 500-800 tonnages.022” wall 95/5 Cupro-nickel975-1350 tonnages .028” wallcopper— Condenser .028” wall copperGeneral Advanced cycle-managementsystem with Adaptive Frequency drive solution control 150 psig (10.3 bar) evaporator,absorber and condenser sections Industrial-grade energy valve Rigging eyes for easy installation Advanced microprocessor controlsystem with adaptive controlfunctions 2-line, 40-character clear-languageinterface to unit functions anddiagnostic information Fixed and floating generator tubesupports prevent thermal stress Efficient stainless steel brazedplate solution heat exchanger Long-life solution pumps Molybdate inhibitor system Factory-installed andcommissioned controls Individually replaceable tubes Removable absorber andevaporator spray treesABS-PRC001-E4

Features andBenefitsHorizon Single-StageAbsorption RefrigerationCycleRefrigeration CycleThis is an example of typicalmachine operation at a standardrating point condition (i.e., 85 F(29.4 C) tower, 44 F (6.7 C) leavingchilled water) at full load. Dilutesolution has a relatively highrefrigerant content and low lithiumbromide content. An intermediatesolution is a mixture of dilute andconcentrated solutions. Aconcentrated solution is one with arelatively low refrigerant contentand high lithium bromide content.Generator (1)Dilute solution is pumped into thegenerator, where it is boiled by thesteam or hot water in the tubebundle, creating refrigerant vapor.The refrigerant vapor flows to thecondenser (2). The nowconcentrated solution flows bygravity, through the solution heatexchanger to the absorber spraysystem, where it is mixed with dilutesolution from the absorber andsprayed on the absorber tubebundle.RefrigerationCycleFigure FB-1 – Single-Stage Absorption Refrigeration Cycle127389116101245Figure Notes:1 – Solution 215ºF (102ºC), Vapor207ºF (97ºC)2 – Refrigerant 100ºF (38ºC), Entering/Leaving Cooling Water 94ºF/102ºF(34ºC/39ºC)3 – Entering/Leaving System Water54ºF/44ºF (12ºC/7ºC), EvaporatorPump Refrigerant 41ºF (5ºC)4 – Leaving Solution 107ºF (42ºC),Entering/Leaving Cooling Water85ºF/94ºF (29ºC/34ºC)5 – Entering Solution 120ºF (49ºC)6 – Solution Heat Exchanger7 – Steam8 – Chilled Water9 – Refrigerant Storage10 – Eductor11 – Cooling Water12 – Evaporator Spray PumpABS-PRC001-E49
Features andBenefitsRefrigerationCycleCondenser (2)Refrigerant vapor, produced by thegenerator, enters the condenser andchanges to a liquid throughcondensation. The heat ofcondensation is rejected to thecooling water inside the tubebundle.Absorption Process (5)Solution (concentrated) enters thespray system from the generatorand enters the spray system,wetting the tubes and providing aliquid surface for the refrigerantvapor (from the evaporator) toabsorb into the lithium bromidesolution. The solutiontemperature/concentration sprayedin the absorber controls theabsorber pressure, therebycontrolling the evaporatorrefrigerant temperature.Evaporator (3)The liquid refrigerant leaves thecondenser through a J tube, wherethe pressure/temperature is reducedthrough expansion for delivery tothe evaporator at 41 F (5 C). Systemwater runs through the tube bundlewhere its heat is transferred to therefrigerant, causing the refrigerantto vaporize/boil. The refrigerantvapor flows to the slightly lowerpressure in the absorber.Absorber (4)Refrigerant vapor is absorbed by thelithium bromide solution. The nowdilute solution is pumped throughthe solution heat exchanger and onto the generator. The heat of vaporabsorption is rejected via thecooling water inside the tubebundle.10Solution Heat Exchanger (6)Solution flows through the heatexchanger to be preheated,reducing the heat energy required toinduce boiling within the generator,and to decrease the temperature ofthe solution being returned to theabsorber, thus decreasing the loadon the cooling tower.ABS-PRC001-E4
ApplicationConsiderations GeneralGeneralThe Horizon single-stage steamfired or hot water absorption chilleris designed to provide 40 F to 60 F(4.4 C to 15.6 C) chilled water, forcomfort or process coolingapplications, within all three marketsegments – commercial, industrialand institutional. They are mostoften used where an economicanalysis of fuel costs versuselectrical rates indicates anoperating cost advantage.In many process applications, theycan be utilized to convert excessheat energy to provide chilled waterfor process or comfort applications.Operating LimitsTrane single-stage absorptionchillers operate with nominal 12psig (0.83 bar) steam or nominal270 F (132 C) hot water. In allapplications, superheat should belimited so steam temperature doesnot exceed 340 F (171 C).ABS-PRC001-E4Waterflows that are within the limitsindicated on the appropriateselection table will ensure tubewater velocities not exceeding 10feet per second (3.05 m/sec) incopper tubes and 11 feet per second(3.35 m/sec) in cupronickel tubes.Changes in condenser watertemperature should not exceed 1 Fper minute in the range from 75 F to95 F (23.9 C to 35 C).Sound and VibrationAbsorption units are well-suited forareas where low sound levels arerequired. The Trane Horizon singlestage steam absorption chiller willoperate under normal loadconditions at less than 85 dBAsound pressure level. Duringoperation there is no vibration ofany components that could bedamaging to the chiller or that couldtransmit objectionable sound orvibration to the building.Chiller InstallationThe following should be consideredwhen installing an absorptionchiller: Rigging and service clearances Foundation support Chiller isolation forsound/vibration reduction Condensate handling Steam supply control Condenser-water temperaturecontrol Chilled-water flow control Chilled- and condenser-water flowlimit Generator hot-water application11
ApplicationConsiderations GeneralCooling-Tower Water FlowThe ARI standard gpm/ton forsingle-stage absorption chillers is3.6, however, lower flow throughthe condenser and absorber sectionwill present an opportunity for asmaller tower, smaller piping, andsmaller condenser pump. For moreinformation on lower flows in thecooling tower water circuit, refer tothe appropriate Trane engineeringbulletin, available from your localTrane representative.Water TreatmentThe use of untreated or improperlytreated water may result in scaling,erosion, and corrosion, algae orslime. It is recommended that theservices of a qualified watertreatment specialist be used todetermine what treatment, if any, isadvisable. The Trane Companyassumes no responsibility for theresults of untreated or improperlytreated water.12Combination SystemsPeak energy savings can beachieved when using a combinationof electric chillers and absorptionchillers for air conditioning loads.The absorption chiller is used toshave seasonal, billable peak-powerdemands during summer operation,and the electric chiller is run belowthe allowed demand limit, reducingcostly demand charges. Trane offersboth electric chillers and absorptionchillers with the unit control panel(UCP2) as standard. Although thechillers have different features andmodes of operation, the chillercontrol panel looks and acts thesame when used with any chillermodel. Each control panel isprogrammed to monitor theparticular chiller for which it wasdesigned, however, maintenanceand service personnel only need tobecome familiar with one controlpanel. Combined with a TraneTracer system, a chiller plant hasalmost unlimited operationalflexibility, and all equipment issupplied from a single source.Multiple Machine InstallationsThe Trane absorption machine canbe applied to series or parallelchilled-water flow, depending uponthe design requirement. Thearrangement that is best for anindividual system should be basedon an analysis of system water andtemperature rise requirements,system and machine pressure-dropcharacteristics, and installation cost.Parallel flow allows minimumchilled-water pressure drop throughthe machines. However, with onemachine “off,” it is not usuallypossible to maintain the designchilled-water temperature unlessone machine is isolated with shutoff valves and the chilled-water flowdecreased.Series flow permits design chilledwater temperature at light loadswith one machine “off.” However, atall operating conditions, the chilledwater pressure drop through themachine is high.Accurate chilled-water temperaturescan be maintained on individualmachines between 100 percent and10 percent of nominal chiller load,which allows for a wide range ofcontrol options. Each chiller has astand-alone control system tomanage the desired watertemperature, and also the ability toreceive remote commands tosupport various system demandsfrom a control center. This versatilityof control makes the managementof more than one machine relativelyeasy.ABS-PRC001-E4
SelectionProcedureSelection ProcedureAbsorption refrigeration machinesare usually selected to provide therequired refrigeration capacity withthe smallest practical machine ofsufficient size. Machine size is basedon chilled-water flow rates andtemperatures specified for the airside of the system.Total air-conditioning system firstcost can be minimized by a carefulanalysis of system operatingparameters. The effect of flow ratesand temperatures, on both thebuilding air side and therefrigeration machine selections,should be investigated to determinewhich system represents the bestinvestment for the owner.The information on the followingpages provides performance data, atARI standard conditions, forcapacity in tons, efficiency, flowrates and water pressure drops. Allcapacities are in accordance withthe expected ARI 560 Standardrevision, and are based on foulingfactors of .0001 for the evaporatorwaterside tubing and .00025 for theabsorber and condenser tubingABS-PRC001-E4Standard FoulingUnit performance at non-standardfouling factors may vary fromstandard performance. Foulingfactors estimate the heat transferpenalty that coincides with the effectof typical fouling in evaporator andabsorber/condenser (cooling) watercircuits. All selections should usethe standard fouling factor to moreaccurately estimate the chillerperformance in an equipment roomand to comply with ARI 560.ARI Standard Fouling FactorsEvaporatorCondenser/AbsorberEnglish Units – hour-ft2-F/Btu0.00010.00025SI Units – m2-K/kW0.0180.044Additional FoulingAny selection that uses a foulingfactor greater than 0.0001 for theevaporator tubes, and 0.00025 forthe condenser/absorber tubes, is amore conservative estimate thatshould only be used if there is anabnormal amount of foulingcontaminants in the water systems.The ARI 560 Standard defines“additional fouling” as “Conditionssuch as water hardness, organicmaterial, suspended solids and/orwater velocity may necessitate theuse of a greater field foulingallowance than that provided in theStandard Rating of equipment.” TheTrane single-stage Horizon Selectionprogram should be used todetermine the effect of nonstandardfouling factors. The followingguidelines can be used forestimation prior to the selection:ARI Standard Fouling Factors ForAdditional FoulingEvaporatorCondenser/AbsorberEnglish Units – hour-ft2-F/Btu0.00020.00026 – 0.00075SI Units – m2-K/kW0.0350.04613
SelectionProcedurePart Load PerformanceThe Horizon single-stageabsorption chiller exhibits excellentpart-load performancecharacteristics. Air conditioningsystem loads are usuallysignificantly less than full-loaddesign conditions. Therefore, theabsorption chiller operates at fullload a small percentage of the time.Part-load absorption chilleroperation is normally associatedwith reduced tower-watertemperatures. At part-loadoperation, the heat rejected to thecooling tower is less than at fullload operation. Also, part-loadoperation is typically associatedwith reduced outside wet-bulbtemperatures, resulting in improvedcooling tower performance. The netresult of less heat rejection andlower wet-bulb temperature iscooler tower water entering thechiller and improved unitperformance.Final SelectionA final selection must be done bythe local Trane sales engineer usingthe Trane Horizon Single-StageAbsorption Selection Program. Forapplications higher than 1600 feet(500 meters) above sea level, finalselection requires review byAbsorption Product Marketing. Priorto accessing the computer selectionprogram, the following data inputsshould be tabulated: Temperature or pressure of the hotwater or steam Two of the following three valuesmust be provided1:– Evaporator Delta-T– Evaporator Flow– Cooling Capacity Leaving-Evaporator WaterTemperature Entering-Absorber WaterTemperature Cooling Water Flow Chilled water and tower waterfouling factorsAny limitations or restrictionsshould also be given (i.e., pressuredrop, gpm etc.).2 Absorption chillers can be selectedwith a wide variety of media otherthan water (evaporator andabsorber/condenser, or both). Formedia other than water, contactthe local Trane sales office forchiller selections and information.1Other options that may also beselected are: Type and thickness of tubematerial Type of solution flowing throughthe evaporator and tower loop2.14ABS-PRC001-E4
