    Introduction

    Th YORK Millennium YS Chillr offrs a comlt com-

    bination of faturs for total onr satisfaction.

    MATCHED COMPONENTS MAXIMIZE EFFICIENCY

    Actual chiller efciency cannot be determined by analyzing

    the theoretical efciency of any one chiller component.It requires a specic combination of heat exchanger,

    comrssor, and motor rformanc to achiv th lo-

    st systm kw/Ton. YORK Millennium chillr tchnology

    matchs chillr systm comonnts to rovid maximum

    chiller efciency under actual not just theoretical op-

    rating conditions.

    REAL-wORLD ENERGY PERFORMANCE

    Johnson Controls ionrd th trm Ral-world enrgy

    to illustrat th nrgy-saving otntial of focusing on

    chillr rformanc during off-dsign conditions. Off-d-

    sign is not only art load, but full load oration as ll,

    ith rducd ntring condnsr atr tmraturs

    (eCwTs). This is hr chillrs orat 99% of th tim,

    and hr orating costs add u.

    Th YS Millennium chillrs ar th only chillrs dsignd

    to orat on a continuous basis ith cold eCwT and full

    condenser ow at all load points, taking full advantage of

    Real-World conditions. This type of operation benets the

    cooling tor as ll; rducing cycling of th fan motor

    and ensuring good coverage of the cooling ll.

    YORK Millennium chillers offer the most efcient Real-world oration of any chillr, maning lor orating

    costs and an xcllnt rturn on your chillr invstmnt.

    OPEN DRIVE DESIGN

    Hrmtic-motor burnout can caus catastrohic damag

    to a chillr. Th ntir chillr must b cland, and th

    rfrigrant rlacd. YORK Millennium scr chillrs

    liminat this risk by utilizing air-coold motors. Rfrig-

    rant nvr coms in contact ith th motor, rvnting

    contamination of th rst of th chillr.

    Insuranc comanis that offr olicis on larg air condi-

    tioning quimnt oftn considr air-coold motors a sig-

    nicant advantage over hermetic refrigerant cooled units.

    HIGH-EFFICIENCY HEAT EXCHANGERS

    Millennium chillr hat xchangrs offr th latst tchnology in hat transfr surfac dsign to giv you maxi-

    mum efciency and compact design. Water-side and

    rfrigrant-sid dsign nhancmnts minimiz both

    nrgy consumtion and tub fouling.

    FACTORY PACKAGING REDUCES FIELD LABOR

    COSTS

    YORK Millennium scr chillrs ar dsignd to k

    installation costs lo. whr installation accss is not a

    roblm, th unit can b shid comltly ackagd

    rquiring minimal iing and iring to comlt th in-

    stallation.

    For thos units utilizing a factory installd Solid-Stat

    Startr, th thr or lads rovid all or to th

    chillr and its auxiliaris.

    TAKE ADVANTAGE OF COLDER COOLING TOwER

    wATER TEMPERATURES

    YORK Millennium scr chillrs ar dsignd to tak ful

    advantag of coldr cooling tor atr tmraturs

    hich ar naturally availabl during most orating hours

    Considrabl nrgy savings ar availabl by ltting tor

    water temperature drop, rather than articially holding itabov 75F (23.9C), scially at lo load, as som

    chillrs rquir.

    U.L. ACCEPTANCE YOUR ASSURANCE OF RELI

    ABILITY

    YORK Millennium scr chillrs ar arovd for listing

    by Undrritrs Laboratoris for th Unitd Stats and

    Canada. Rcognition of safty and rliability is your as-

    suranc of troubl-fr rformanc in day-to-day building

    oration.

    ARI CERTIFICATION PROGRAM

    Th rformanc of YORK Millennium chillers is certied

    to th Air Conditioning and Rfrigration Institut (ARI)

    complying with the certication sections of the latest issue

    of ARI Standard 550/590. Under this Certication Pro-

    gram, chillrs ar rgularly tstd in strict comlianc ith

    this Standard. This rovids an indndnt, third-arty

    verication of chiller performance.

    COMPUTERIZED PERFORMANCE RATINGS

    each chillr is custom-matchd to mt th individual

    building load and nrgy rquirmnts. A larg numbr

    of standard hat xchangrs and ass arrangmnts ar

    availabl to rovid th bst ossibl match.

    It is not ractical to rovid tabulatd rformanc for

    ach combination, as th nrgy rquirmnts at both full

    and part- load vary signicantly with each heat exchanger

    and ass arrangmnt. Comutrizd ratings ar avail-

    able through each Johnson Controls sales ofce. These

    ratings can be tailored to specic job requirements, and

    are part of the ARI Certication Program.

    OFF-DESIGN PERFORMANCE

    Since the vast majority of its operating hours are spentat off-dsign conditions, a chillr should b chosn not

    only to mt th full-load dsign, but also for its ability to

    perform efciently at lower loads and lower tower water

    tmraturs. It is not uncommon for chillrs ith th

    sam full-load Kw/TON to hav an orating cost diffr-

    nc of ovr 10% du to art-load oration.

    part-load information can b asily and accuratly gnr-

    atd by comutr. And bcaus it is so imortant to an

    onrs orating budgt, this information is no stan-

    dard within the ARI Certication Program in the form of

    an Intgratd part-Load Valu (IpLV), and Non-Standardpart-Load Valu (NpLV).

    Th IpLV / NpLV formulas from ARI Standard 550/590

    closly track chillr orations, and rovid a mor ac-

    curat indication of chillr rformanc than th rvi-

    ous IpLV / ApLV formula. A mor dtaild analysis must

    take into account actual building load proles, and local

    athr data. part-load rformanc data should b ob-

    tained for each job using its own design criteria.

    Ratd in accordanc ith th latst

    issu of ARI Standard 550/590.

    oint has a o-u scrn ith th alloabl rangs, so

    th chillr cannot b rogrammd to orat outsid ofits dsign limits.

    Thrmal ic storag systms ar basd on th conct

    of using off-ak, lor cost lctricity to build ic for

    handling th cooling load during ak hours. Th most

    efcient way to build ice is to maximize chiller load and

    minimiz run tim. Standard chillr control systms ar not

    dsignd for this orating mod. In a tyical alication,

    chillrs ill load and unload to maintain a laving chilld

    liquid stoint. whn th YORK YS chillr orats in th

    thrmal storag control mod, th unit ill rmain at 100%

    load until th stoint shutdon tmratur is rachd.

    This control nhancmnt is standard on all YS chillrs.

    Th chillr can also b lft in th standard control mod

    for tmraturs ranging btn 20 and 70F (-6.7 and

    21.1C), for alications involving a rocss cooling duty

    STANDARD UNIT

    General

    Th YORK Millnnium YS Rotary Scr Chillr is com-

    ltly factory-ackagd, including vaorator, condnsr,

    sub-coolr, oil sarator, comrssor, motor, lubricationsystm, control cntr and rfrigrant isolation valvs.

    Th factory ackag consists of a lak tight dsign. All

    units shi as standard ith a full charg of rfrigrant

    and oil. Units can also b shid in sctions (otional)

    to accommodate job site requirements.

    The services of a Johnson Controls factory-trained, eld

    srvic rrsntativ ar incurrd to survis or rform

    the nal leak testing, charging, the initial start-up, and

    concurrnt orator instructions.

    Compressor

    Th Frick Rotary Tin Scr Comrssor is nginrd

    and constructd to mt th xact rquirmnts of th

    industrial rfrigration markt. It utilizs stat-of-th-art

    tchnology to rovid th most rliabl and nrgy-f-

    cient compressor available at all operating conditions.

    Th comrssor orats at 3750 RpM for 60 Hrtz and

    2975 RpM for 50 Hrtz. Th comrssor housing is mad

    of cast iron, rcision-machind to rovid minimal clar-

    anc for th rotors. Comrssor housing has a dsign

    orking rssur (Dwp) of 300 pSIG (2068 kpa) mini-

    mum, and hydro-tstd at 544 pSIG (3751 kpa).

    Th rotors ar manufacturd from forgd stl and usasymmetric proles. The compressor incorporates a

    comlt anti-friction baring dsign for rducd or

    and incrasd rliability. Four sarat cylindrical rollr

    barings handl radial loads. To 4-oint angular contact

    ball barings handl axial loads. Togthr, thy maintain

    accurat rotor ositioning at all rssur ratios, thrby

    minimizing blow-by and maintaining efciency.

    A chck valv is installd in th comrssor discharg

    housing (suction housing for S4 and S5 comrssor) to

    rvnt comrssor rotor back sin bcaus of systm

    rfrigrant rssur gradints during shutdon.

    Th on-driv comrssor shaft sal consists of rci-

    sion cramic sal facs, mtallic bllos, rotating mmbr,

    PTFE C-Ring static seal, and multi-port oil injection ring.

    Th sal cavity is maintaind at intrmdiat rssur

    ith its oil dischargd to th oil drain from th comrssor.

    Combining intermediate pressure with direct oil injection

    rovids cool, non-foaming lubricant to th sal assuring

    a longr lifsan.

    Capacity Control

    Caacity control is achivd by us of a slid valv hich

    rovids fully modulating caacity control from 100% to

    10% of full load. Th slid valv is actuatd by oil rssur

    controlld by xtrnal solnoid valvs via th OtiVi

    Control Cntr.

    Oil SeparatorTh oil sarator is a horizontal dsign ithout moving

    arts. effctiv oil saration is achivd by gravity dro

    out of oil from th rfrigrant gas as vlocity dcrass

    uon ntring th sarator, and by msh ads to rovid

    nal gas/oil separation before gas enters the condenser

    Th oil sarator is dsignd for 345 pSIG (2378 kpa

    ing-ty rlif valvs sizd for rssur vssl volum

    ach unit is quid ith a rutur disk. This rutur

    disk is abl to rliv th ntir uming caacity of th

    comrssor if lctronic saftis fail, roviding rotc-

    tion for rorty and rsonnl. This dvic is st for

    345 pSIG (2378 kpa). Altrnativly, th shll sid may

    b dsignd to euroan prssur Vssl Cods and

    stamd in accordanc ith A.D. Mrkblattr or othr

    euroan prssur Vssl dsign cod. whn rquird

    by th rfrigration safty cod, ach vssl has a dua

    rfrigrant rlif dvic(s).

    LubricationTh main unit oil rsrvoir is locatd in th oil sarator

    Th comrssor also has an oil rsrvoir locatd at th

    rotor barings to rovid lubrication during start-u, coa

    don, and in th vnt of a or failur. During ora

    tion, system pressure differential provides proper oil ow

    ithout th nd of an auxiliary oil um. This minimizs

    nrgy consumtion.

    The chiller is shipped with a 3 Micron absolute oil lter

    nsuring a clan oil systm and surior comrssor

    life. An external, replaceable cartridge oil lter is supplied

    ith manual isolation sto valvs for as of srvicing

    An optional dual oil lter housing with isolation valves is

    availabl on all units. This allos immdiat sitching

    from one lter to the other, eliminating downtime during

    lter changes. The off-line oil lter can be changed during

    chillr oration.

    atr from th vaorator and condnsr hn th ums

    ar shut off. piing should b adquatly suortd and

    bracd indndntly of th chillr to avoid th imosi-

    tion of strain on chillr comonnts. Hangrs must allo

    for alignmnt of th i. Isolators in th iing and in

    th hangrs ar highly dsirabl in achiving sound andvibration control.

    Convenience Considerations To facilitat th r-

    formanc of routin maintnanc ork, som or all of th

    folloing sts may b takn by th urchasr. Coolr and

    condnsr atr boxs ar quid ith luggd vnt and

    gaugs ith sto cocks, and sto valvs, may b installd

    in th inlts and outlts of th condnsr and chilld atr

    lin as clos as ossibl to th chillr. An ovrhad monorail

    or bam may b usd to facilitat srvicing.

    Connections Th standard chillr is dsignd for 150

    sig (1034 kpa) dsign orking rssur in both th

    chilld atr and condnsr atr circuits. Th connc

    tions (atr nozzls) to ths circuits ar furnishd ith

    groovs for ANSI/AwwA C-606 coulings. piing should

    b arrangd for as of disassmbly at th unit for tubclaning. All atr iing should b thoroughly cland

    of all dirt and debris before nal connections are made

    to th chillr.

    Chilled water A ow switch must be installed in the

    chilld atr lin of vry unit. Th sitch must b locatd

    in th horizontal iing clos to th unit, hr th straigh

    horizontal runs on each side of the ow switch are at leas

    ve pipe diameters in length. The switch must be electri

    cally connctd to th chilld atr intrlock osition in

    (3.2 mm) perforated holes must be eld-installed in the

    chilld atr inlt lin as clos as ossibl to th chillrIf locatd clos nough to th chillr, th chilld atr

    pump may be protected by the same strainer. The ow

    switch and strainer assure chilled water ow during unit

    operation. The loss or severe reduction of water ow could

    sriously imair th chillr rformanc or vn rsult in

    that shuts off ow to the idle evaporator. When units are

    alid in sris ith lad/lag caability, th units should

    b idntical.

    REFRIGERANT RELIEF PIPING

    each chillr is quid ith rssur rlif dvics. Th

    uros of th rlif dvics is to quickly rliv xcss

    rssur of th rfrigrant charg to atmoshr, as a

    safty rcaution in th vnt of an mrgncy such as

    a re. They are set to relieve at an internal pressure of300 sig (2069 Kpa) and ar locatd on th condnsr,

    vaorator and oil sarator; and ar rovidd in ac-

    cordanc ith ASHRAe 15 Safty Cod and ASMe or

    alicabl rssur vssl cod. whn rquird and ds-

    ignatd on th ordr form, th rlif dvics ill satisfy th

    euroan rquirmnts: (xaml VBG20). Undr ths

    circumstancs th rlif dvics may b rlif valvs,

    or a combination of ths dvics.

    In addition to th sring-loadd, r-sating-ty rlif

    valvs that ar sizd for rssur vssl volum, ach unit

    is quid ith a rutur disk. This rutur disk is abl

    to rliv th ntir uming caacity of th comrssor

    SOUND AND VIBRATION CONSIDERATIONS

    AMillennium chiller is not a source of objectionable sound

    and vibration in normal air conditioning alications.

    Norn isolation mounts ar furnishd as standard

    with each unit. Optional level-adjusting spring isolator as-

    semblies designed for 1 static deection are available.

    Millennium chillr sound rssur lvl ratings ill b

    furnishd uon rqust.

    Control of sound and vibration transmission must b takn

    into account in th quimnt room construction as ll

    as in th slction and installation of th quimnt.

    THERMAL INSULATION

    No arciabl orating conomy can b achivd by

    thrmally insulating th chillr. Hovr, th chillrs

    cold surfacs should b insulatd ith a vaor barrir

    insulation sufcient to prevent condensation. A chiller can

    b factory insulatd ith 3/4 (19mm) or 1-1/2 (38mm)

    thick insulation, as an otion. This insulation ill normally

    rvnt condnsation in nvironmnts ith dry bulb tm-

    raturs of 50F to 90F (10C to 32C) and rlativ

    humidities up to 75% [3/4 (19mm) thickness] or 90% [1-

    1/2 (38mm) thicknss]. Th insulation is aintd and thsurface is exible and reasonably resistant to wear. It is

    intndd for a chillr installd indoors and, thrfor, no

    rotctiv covring of th insulation is usually rquird

    If insulation is applied to the water boxes at the job site

    it must b rmovabl to rmit accss to th tubs for

    routin maintnanc.

    VENTILATION

    Th ASHRAe Standard 15 Safty Cod for Mchanica

    Rfrigration rquirs that all machinry rooms b vntd

    to th outdoors utilizing mchanical vntilation by on

    or mor or-drivn fans. This standard, lus Nationa

    Fir protction Association Standard 90A, stat, loca

    and other related codes should be reviewed for specic

    rquirmnts. Sinc th Millennium chillr motor is air-

    coold, vntilation should allo for th rmoval of ha

    from th motor.

    In addition, th ASHRAe Standard 15 rquirs a rfrigr

    ant vaor dtctor to b mloyd for all rfrigrants. It isto b locatd in ara hr rfrigrant from a lak ould

    b likly to concntrat. An alarm is to b activatd and
