of solution reconcentration, making itthe most basic of the cycles avail-able today. Simplicity of design, com-bined with its numerous other qualityfeatures, equates to inherently highreliability. Few moving parts andsimple, dependable operation reducedowntime, as well as service andmaintenance costs. The 16JB chilleroffers typical full-load steam ratesof approximately 18 lb/hr-ton at stand-ard ARI (Air Conditioning and Re-frigeration Institute) operatingconditions.Superior part-load performance— The 16JB’s standard concentrationcontrol system allows stable, part-load operation at cooling water tem-peratures as low as 55 F (12.8 C)without the need for a cooling towerbypass. In addition, a control valveensures stable, continuous evaporatorpump operation at part-load condi-tions. The 16JB has a continuousoperating range from 100% to10% ofmachine capacity.

Application versatilityDesigned to suit a variety of appli-cations — The use of steam or hotwater from a number of sources allowsthe 16JB machine to meet a varietyof cooling needs. Waste heat sourcesgenerated from industrial processesand cogeneration systems can be uti-lized to provide chilled water forprocess cooling as well as comfortcooling, reducing the need forpurchased energy and contributing toeven greater energy savings.Ideal for new or retrofit applica-tions — Whether intended for re-placement of existing chiller systemsor for new construction purposes, the16JB is well suited to meet the needsof almost any cooling application. The16JB’s 15 model sizes, spanning acapacity range of 108 to 680 tons,make the 16JB single effect absorptionchiller the ideal choice for comfortcooling and/or light industrial applica-tions. Carrier’s computerized perfor-mance ratings assist in the selection ofthe appropriate machine, properlysized to meet exact job requirements.Dependable operation, as well aslow sound and vibration levels, en-sures occupant comfort, even wheninstalled on upper floors.Combine absorption andelectric-driven chillers — Utilizingboth absorption and electric chillers in

a central plant offers the flexibility tobase load one chiller, while usingthe other to handle peak load require-ments. Hybrid chiller systems haveproven to be an economical solutionfor many comfort cooling installations.In many geographical areas, operat-ing the electric chiller as the baseloaded machine, while utilizing theabsorption chiller during peak loadconditions, avoids or reduces electricdemand charges. Depending on utilityrate structures, a 16JB single effectabsorption chiller used in conjunctionwith an electric-driven chiller maybe the most efficient and cost-effectivecombination available.

Features/Benefits (cont)

Single point electrical connection— Installation costs are further re-duced by eliminating field wiring be-tween machine components. All unit-mounted electrical items arefactory-wired to the chiller controlcenter and require only a single pointelectrical connection to the machinefrom the building’s electrical service. Amulti-tap transformer mounted in thechiller panel provides secondarysingle-phase power for the 16JBcontrols.Low sound and vibration levelsallow location flexibility — Lowsound and vibration levels are charac-teristic of absorption chillers, prima-rily due to the fact that the only rotatingparts are the refrigerant and solutionpumps. The overall sound level ofa Carrier 16JB is typically 80 dbA.This allows the machine to be installednear occupied spaces or in areaswith strict sound requirements. Lowvibration levels also make it possibleto install the chiller on upper flowswithout special consideration for vibra-tion dampening systems.

Low maintenanceStandard features simplify main-tenance procedures — Every 16JBis provided with numerous standarddesign features that provide for conve-nient and simple maintenance. Re-movable waterbox covers on theevaporator, absorber, and condenserfacilitate tube and waterbox inspectionfrom either end. All moving partsare easily accessible for inspection orreplacement, as required. The U-bendtube design in the generator greatlyreduces the likelihood of expensiveand time-consuming tube bundlereplacement. Unlike ordinary tubes,the U-bend configuration allows theentire tube bundle to expand orcontract as a unit when subjected torapid temperature changes. The tubebundle floats and adjusts freely as aunit, decreasing tube wear due to ther-mal stresses and reducing tube bundlefailures. Each shell is divided by a‘‘U-baffle’’ forming a double sump.The U-baffle design not only forms athermal barrier between the sec-tions but also allows the solution orrefrigerant to be stored temporarily onone side of the vessel while the otherside is being serviced, consequentlyreducing maintenance costs.

Factory-trained service organiza-tion — Carrier’s extensive serviceorganization offers trained and experi-enced service technicians in everymajor city. In addition to routine main-tenance and repair services,Carrier also offers a wide array of pre-ventative maintenance, full mainte-nance, and/or extended service con-tracts which can be custom-tailored tofulfill any service requirements.Leakproof hermetic pumps cutmaintenance costs — Carrier’sproven solution and refrigerant pump/motors are leakproof, completelyself-contained, and hermetically sealed.The hermetic design eliminates theneed for a separate, complicated, andpossibly leakprone seal water systemand auxiliary water piping, whileproviding leak tightness and longermachine life. There are no pack-ing glands or seals to maintain — aircannot leak in, fluids cannot leak

out. Specially designed bearings ab-sorb both radial and axial thruststo ensure correct fit at all times. Thereis no possibility of external contami-nation since the fluid being pumpedlubricates and cools the pump andmotor assemblies. In addition, boththe rotor and stator are separated bya stainless steel liner that protectsthe windings from the fluid beingpumped. As an additional safety fea-ture, thermal overload switches areembedded in the stator to protectagainst high winding temperature. Thepumps are field serviceable and in-spection is recommended after 6years of operation. Pump isolationvalves are not included on 16JB ma-chines to minimize potential leakpaths into the machine. The pumpisolation valves are not requiredbecause of the exceptionally highreliability of the pump/motorassemblies.

Reliable operation16JB control system featuresautomatic monitoring and precisecontrol of machine operation —Each Carrier 16JB single effect chillerincludes a factory mounted and wiredcontrol center which is functionallytested prior to shipment. Continuousmonitoring and control of machineoperation is performed automatically.Chiller operational status is displayedon the front of the panel. Controlcenter components include an elec-tronic (or optional pneumatic) capacitycontrol module, fused disconnectswitch, pump contactors, ambient-compensated 3-phase pump overloads,

multi-tap control power transformer,elapsed time indicator, terminalblocks, relays, auto/manual concen-tration control switch, refrigerant andsolution pump operational switch,exhaust purge light, and all other nec-essary safeties and controls for propermachine operation.Superior corrosion protection —Absorption chillers must be protectedfrom the internal corrosion that isalways present when lithium bromidesolution is in contact with internalmachine surfaces. The Carrier 16JBabsorption chiller incorporates ahighly effective corrosion inhibitor toprovide an extra margin of protec-

tion against internal corrosion. Otherinhibitors may necessitate the useof exotic tube materials in certain heatexchangers since they are less effec-tive and require frequent maintenanceand analysis. The superior corrosionprotection of the inhibitor allowsfor the use of standard copper tubesthroughout the machine (except forthe generator [90/10 cupro-nickel]).This results in long machine life anddependable operation.Rugged machine construction —Every Carrier 16JB offers numer-ous standard features designed toprovide reliable, trouble-free opera-tion. The machine is fabricated to

meet stringent manufacturing anddesign requirements. Non-clogging,corrosion-proof spray nozzles ensureagainst both corrosion and possibleblockage for continuous, reliableoperation. U-bend tubes of 90/10cupro-nickel in the generator allowthe tube bundle to expand and adjustfreely when subjected to rapid tem-perature changes. Allowing for thisthermal growth and expansion reducestube wear and helps prevent prema-ture tube failure. The numerous stand-ard features mean that every 16JBsingle effect chiller is built to withstandthe most rigorous duty, whether it isused for comfort cooling or lightprocess applications.Automatic motorless purge ex-tends machine life, ensures opti-mum efficiency and performance— The purge system on an absorp-tion chiller is critical to ensuring longmachine life and efficient opera-tion. All absorption chillers operate ina vacuum and generate hydrogen(and other noncondensable gases) in

small quantities, whether they arevacuum tight or properly inhibited.These gases are present in sufficientvolume to interfere with propermachine operation, making it impera-tive that they be removed to protectagainst internal corrosion, lithium bro-mide solution crystallization, and/orreduction of chiller capacity. The Car-rier motorless purge system protectsagainst these potential hazards byoperating continuously duringmachine operation.How the motorless purge operates— During operation, any noncondens-ables which are present tend to accu-mulate in the absorber section whichoperates at the lowest internalpressure. A slip-stream of lithium bro-mide solution from the discharge ofthe solution pump flows throughan eductor, creating a suction whichdraws the noncondensables fromthe absorber, entraining them with thesolution flowing through the eductor.The two eductors discharge the so-lution and noncondensables into a

storage tank, where some of thenoncondensables are separated fromthe solution. The solution and remain-ing noncondensables flow to a sepa-rator where the remainingnoncondensables are separated andflow back to the storage chamber,while the solution returns to the ab-sorber sump through the genera-tor overflow pipe.As noncondensables accumulate in

the external storage chamber, they areisolated from the chiller and cannotre-enter the machine, even duringshutdown. These gases must periodi-cally be exhausted (normally onceor twice a year) from the storagechamber by a simple procedure whichcan be performed while the machineis running. Evacuation is accomplishedby manually positioning valves topressurize the storage chamber withlithium bromide solution and thenexhausting the noncondensable gasesinto the atmosphere.

Carrier Cycle-Guard™ anti-crystallization controls maintainproper solution concentration— The 16JB automatically limits solu-tion concentration in several ways toavoid both crystallization and overdilu-tion to provide dependable, trouble-free operation. Crystallization of thelithium bromide solution dependson the combination of temperatureand concentration. Carrier’s Cycle-Guard concentration control sys-tem automatically monitors the refrig-erant water level in the evaporatorin conjunction with the solution tem-perature returning to the absorber.Because concentration varies with theamount of water in the lithium bro-mide solution, a rising evaporatorlevel indicates less water in the solu-tion and thus a higher solution concen-tration. When the refrigerant in theevaporator rises to a preset level,

water is transferred from the evapora-tor to the absorber, thus preventingoverconcentration to ensure continu-ous, reliable operation even at coolingwater temperatures as low as 55 F(12.8 C).

The 16JB also incorporates asimple, passive method of control tocorrect any crystallization that wouldnormally start to occur on theshellside of the low temperature solu-tion heat exchanger under abnor-mal conditions. As the hot solutionbegins to back up in the generator asa result of any shellside blockage, itrises above the overflow pipe andreturns directly to the absorber. It issubsequently pumped through thetubeside (heating the shellside) torestore proper operation.

In addition, the 16JB automaticdilution cycle ensures proper concen-

tration after a scheduled unit shut-down so that the unit will not crystal-lize when the machine cools toambient or machine room tempera-ture. The dilution cycle controls opera-tion of the pumps until the refrigerantdrops to a predetermined level andthe dilution level switch opens. Theopening of the dilution level switchdeenergizes the pumps after shutdown.This dilutes the solution to preventan overconcentration condition. Crys-tallization is also minimized by thegravity drain feature of the generatoron the 16JB. The force of gravity andtop-mounting of the generator abovethe absorber enable the strong so-lution to drain out of the genera-tor should a power outage occur.

16JB single effect absorptioncooling cycle — The 16JB singleeffect absorption chiller consists of anevaporator, absorber, condenser,steam or hot water generator, solutionheat exchanger, refrigerant/solutionpumps, purge, controls, and auxil-iaries. Water is used as the refrigerantin vessels maintained under low ab-solute pressure (vacuum). The chilleroperates on the principle that undervacuum, water boils at a low tempera-ture (in this case approximately 40 F[4.4 C]), thereby cooling the chilledwater circulating through the tubes ofthe evaporator. A refrigerant pumpis used to circulate the refrigerantwater over the evaporator tubes toimprove heat transfer.

To make the cooling process con-tinuous, the refrigerant vapor must beremoved as it is produced. A lithiumbromide solution (which has a highaffinity for water) is used to absorb thewater vapor. As this process contin-ues, the lithium bromide becomesdiluted, which reduces its absorptioncapacity. A solution pump then trans-fers this weak (diluted) solution tothe generator where it is reconcen-trated by the introduction of steam orhot water to boil off the previouslyabsorbed water. The water vaporreleased in the shellside of the genera-tor then enters the condenser to becooled and returned to a liquid state.At this point, the refrigerant waterreturns to the evaporator to begin anew cycle.

To remove heat from the machine,relatively cool water from a coolingtower or other source is first circulatedthrough the tubes of the absorber toremove the heat of vaporization. Thissame water is then circulated throughthe tubes of the condenser. Thestrong (reconcentrated) solution fromthe generator flows back to the ab-sorber to also begin a new cycle. Forefficiency reasons, the strong solu-tion from the generator is passedthrough a solution heat exchanger topreheat the weak solution whileprecooling the strong solution beforereturning to the absorber.

Application data

Vent and drain connectionsAll vent and drain connections are found on the waterboxcovers. Connection size is 3⁄4 in. FPT.Provide high points of the machine piping system with

vents and the low points with drains. If shutoff valves areprovided in the main water pipes near the unit, a minimumamount of system water is lost when the heat exchangersare drained.It is recommended that pressure gages be provided at

points of entering and leaving water to measure pressuredrop through the heat exchanger. Gages may be installedas shown in the table below. Pressure gages installed at thevent and drain connections do not include nozzle pressurelosses.Use a reliable manometer to measure pressure differen-

tial when determining water flow. Regular gages are insen-sitive and do not provide an accurate measurement of flowconditions.

Electronically controlled, single effect (one-stage) ab-sorption liquid chiller utilizing hermetic refrigerant andsolution pumps, lithium bromide solution as the ab-sorbent, and water as the refrigerant. Low pressuresteam or hot water shall be supplied to the generatoras the heat source.

1.02 QUALITY ASSURANCEA. Chiller performance shall be rated in accordance with

ARI Standard 560 (latest edition).B. Chiller shall bemanufactured in accordance with ANSI/

ASHRAE 15 (latest edition) Safety Code for Mechani-cal Refrigeration.

C. The tubeside of the absorber and evaporator sections(when applicable) and the tubeside of the generator(for hot water applications) shall be designed, con-structed, and stamped in accordance with ASME Sec-tion VIII, Division 1 requirements.

D. Each chiller shall undergo a series of standard factorytests to ensure that the unit is leak tight, that all elec-trical components operate as intended, and that ev-ery aspect of unit fabrication meets stringent qualitystandards in accordance with good practice and themanufacturer’s quality assurance requirements.1. The shellside of each chiller shall be leak tested by

pressurizing to 15 psig (103 kPa) with dry air andthen checked by spraying a soap/water mixtureon all welds, tube joints, and/or gasketed joints toidentify any major leaks. Afterward, a mass spec-trometer test shall be performed by evacuating theunit to 0.10 mm Hg absolute, covering the ma-chine with a vinyl tent and introducing helium gasunder the tent. Any remaining leaks will allow thehelium to be drawn into the shellside of the ma-chine. The acceptable total leak rate as measuredby the mass spectrometer test shall not exceed.00002 cc/sec standard air.

2. The tubeside of the evaporator, absorber, con-denser, and (steam) generator shall be hydrostati-cally tested at 1.5 times rated design pressure andheld for 1 hour. For hot water applications, a pneu-matic test shall be performed on the generator at1.25 times rated design pressure.

3. All machine wiring shall undergo an insulation re-sistance test. The machine control center and allelectrical components shall also be functionallytested to verify continuity and proper electricaloperation.

4. Final assembly inspection shall consist of verifyingthat all valves, controls, instrumentation, pumps,purge components, and all other machine com-ponents have been properly installed on themachine.

5. Each unit shall then be checked for overall appear-ance and dimensional accuracy.

6. Final inspection shall be performed on each unitto check that painting of the unit is as specified,nameplate data is correct, and that all accessoriesare furnished as required.

1.03 DELIVERY, STORAGE, AND HANDLINGA. Unit shall be stored and handled in accordance with

the manufacturer’s recommendations.B. Unit shall not be factory-charged with lithium bro-

mide solution to prevent possible internal corrosiondamage from occurring should the inside of the ma-chine be accidentally exposed to air during shipmentand/or installation. Charging of lithium bromide so-lution shall be performed at the jobsite in accordancewith the manufacturer’s written instructions.

C. One-piece units shall be shipped under vacuum onthe shellside. Two-piece units shall be shipped with5 psig (34 kPa) nitrogen pressure.

D. Chiller shall be shipped with nameplates indicatingname of manufacturer, model size, serial number, andall other pertinent machine data.

E. Chiller shall include shipping rails as standard for easeof sliding or moving a unit into position to simplifyinstallation. Neoprene isolation pads shall also be in-cluded with the machine as standard.

1.04 WARRANTYManufacturer shall guarantee the chiller against de-fects in materials or workmanship for a period of oneyear from date of initial operation or 18 months fromdate of shipment, whichever occurs first. Manufac-turer shall provide the labor to repair or replace anypart found to be defective in material or workman-ship within the warranty period.

Part 2 — Products2.01 EQUIPMENTA. General:

Absorption liquid chiller shall include evaporator, ab-sorber, condenser, generator, solution heat exchanger,refrigerant/solution pumps, purge system, piping, wir-ing, controls, and auxiliaries. Shipment of the ma-chine shall be in 1 or 2 piece(s), depending on modelsize. Initial charge of lithium bromide shall be in-cluded with the chiller for charging at the jobsite. Gen-erator shall be designed for operation on either lowpressure steam or hot water as specified on the equip-ment schedule. A U-baffle shall be provided in boththe upper and lower shell to serve as a natural insu-lating barrier between sections. The double sumpformed by the U-baffle in the bottom of the absorber-evaporator section shall allow temporary storage ofrefrigerant or solution, thereby reducing service timeand expense by alleviating the need to remove thefluids from the machine during service and/or main-tenance operations.
