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

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.

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

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

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.
A 500 att (115 volt - 1-has - 60/50Hz) immrsion
oil hatr is locatd in th oil sarator rsrvoir, tm-
perature actuated to efciently remove refrigerant from
th oil. Oil hatr or suly is factory ird from

and initial chillr slctions should b mad accordingly to
permit proper range of ow while maintaining the minimum
velocity noted above. Variable ow in the condenser is not
rcommndd, as it gnrally raiss th nrgy consum-
tion of th systm by king th condnsr rssur

Temperature Ranges For normal atr chilling duty,
laving chilld atr tmraturs may b slctd
between 38F (3.3C) [36F (2.2C) with Smart Freeze
nabld) and 70F (21.1C) for atr tmratur rangs
btn 3F and 30F (1.7C and 16.7C).

ncssary to rovid a largr alloanc for fouling, and/or
to scify scial matrials of construction.
General Piping All chilld atr and condnsr atr
iing should b dsignd and installd in accordanc
ith acctd iing ractic. Chilld atr and con-
dnsr atr ums should b locatd to discharg
through the chiller to assure positive pressure and ow
through th unit. piing should includ offsts to rovid
exibility and should be arranged to prevent drainage of
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.

condnsr atr boxs ar quid ith luggd vnt and
drain connctions. If dsird, vnt and drain valvs may b

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.

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

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
th unit control cntr. A atr strainr of maximum 1/8
(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

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
