SPECIFICATIONThe YORK Rotary Screw Chiller is completely factory packaged includingevaporator, condenser, subcooler, oil separator, compressor, motor, lubricationsystem, Control panel, and all interconnecting unit piping and wiring. The unitcontains the full charge of R134a and oil.

CompressorThe rotary twin screw compressor has been engineered and constructed to meetthe exacting requirements of the industrial refrigeration market. It utilizes state-of-the-art technology to provide the most reliable and energy efficient compressoravailable at all operating conditions. The compressor operates at 2975 rpm. Thecompressor housing is made of cast iron, precision machined to provide minimalclearance for the rotors. The compressor housing has a design working pressureof 2413 kPa and is hydro-tested to 3751 kPa.

The rotors are manufactured from forged steel and use asymmetric profiles. Thecompressor incorporates a complete anti-friction bearing design for reduced powerand increased reliability. Four separate cylindrical roller bearings handle radialloads. Two 4-point angular contact ball bearings handle axial loads. Together theymaintain accurate rotor positioning at all pressure ratios thereby minimizing blow-by and maintaining efficiency.

A non return valve is installed in the compressor discharge housing (suction forS4 and S5 compressor) to prevent compressor rotor backspin due to systemrefrigerant pressure gradients during shutdown.

SPECIFICATION (CONTINUED)The open-drive compressor has a doubleshaft seal and consists of a bellows type,spring-loaded precision lapped ceramicring, PTFE static seal and a precisionlapped ceramic rotating collar. The entireshaft seal cavity is at low pressure, beingvented to the oil drain from thecompressor. Combining low pressurewith direct oil cooling provides long seallife.

Capacity ControlCapacity control is achieved by use of aslide valve which provides fullymodulating control from 100% to 15%of full load, depending upon unitselection. The slide valve is actuated byoil pressure controlled by externalsolenoid valves via the control panel.

Motor Driveline

The compressor motor is an open drip-proof, squirrel cage, type constructed toYORK design specifications andoperates at 2975 rpm. The open motoris provided with a D-flange, factorymounted to a cast iron adaptor mountedon the compressor. This unique designallows the motor to be rigidly coupled tothe compressor to provide factoryalignment of motor and compressorshafts.

The motor drive shaft is directlyconnected to the compressor shaft witha flexible disc coupling. The coupling isof all metal construction with no wearingparts to assure long life, and nolubrication requirements to provide lowmaintenance.

For units util izing remote electro-mechanical starters, a steel terminal boxwith gasketed front access cover isprovided for field connected conduit.There are six or three terminals(depending of motor) brought throughthe motor casing into the terminal box.Jumpers are supplied for three-leadtypes of starting. Motor terminal lugs arenot supplied. Overload/overcurrenttransformers are supplied with all units.For units supplied with factory packagedSolid State Starters, refer to theAccessories and Options Section.

Oil Separator

The combined oil separator/reservoir witha design working pressure of 20 bar shallbe the high efficiency, augmented gasimpingement type to maximise oilextraction without fragile media to breakdown.

LubricationThe main oil reservoir is located in theoil separator. The compressor also hasan oil reservoir located at the rotorbearings to provide lubrication duringstartup, coastdown and in the event of apower failure. During operation, systempressure differential provides proper oilflow without the need of an oil pump.This minimizes system energyconsumption.

The chiller is shipped with a 3 micronabsolute oil filter, ensuring a clean oilsystem and superior compressor life. Anoptional dual oil filter housing withisolation valves is available on all units.This allows immediate switching fromone filter to the other, eliminatingdowntime during filter changes. The off-line filter can be changed during chilleroperation.

A 500 watt (115 volt - 1 phase - 50Hz)immersion oil heater is located in the oilseparator reservoir, temperatureactuated to effectively remove refrigerantfrom the oil. Power wiring is provided tothe control panel. A refrigerant cooledoil cooler is provided, factory piped tothe system. An external, replaceablecartridge, 15 micron oil filter is providedwith manual isolation stop valves forease of servicing. An oil eductorautomatically removes oil which mayhave migrated to the evaporator andreturns it to the compressor.

Adjustable remote reset range (up to11C) provides flexible, efficient use ofremote signal depending on resetneeds.

Thermal (Ice) Storage Control ModeThermal ice storage systems are basedon the concept of using off-peak, lowercost electricity to build ice for handlingthe cooling load during peak hours. Themost efficient way to build ice is tomaximize chiller load and minimize runtime. Standard chiller control systemsare not designed for this operating mode.In a typical application, chillers will loadand unload to maintain a leaving chilledliquid setpoint.

When the YORK YN Chiller operates inthe thermal storage control mode, theunit will remain at 100% load until thesetpoint shutdown temperature isreached. To add greater operatingflexibility and eliminate unnecessarychiller cycling, two different Low Water(Liquid) Temperature Restart Thresholdscan be programmed, one for the icemode and one for the standard coolingmode.

This control enhancement is standardon all YN chillers. The chiller can alsobe left in the standard control mode fortemperatures between 6.7 to 0C, forapplications involving a process coolingduty that requires leaving chilled liquidtemperature setpoint control.

APPLICATION DATAThe following information on theapplication and installation of YN chillerswill ensure the reliability and trouble-freelife for which this equipment wasdesigned. While this guide is directedtowards normal, water-chillingapplications, the YORK salesrepresentative can provide completerecommendations on other types ofapplications.

LocationYN chillers are virtually vibration-free andmay generally be located at any level ina building where the construction willsupport the total system operatingweight.

The unit site must be a floor, mountingpad or foundation which is level within8mm and capable of supporting theoperating weight of the chiller.

Sufficient clearance to permit normalservice and maintenance work shouldbe provided all around and above theunit. Additional space should be providedat one end of the unit to permit cleaningof cooler and condenser tubes asrequired. A doorway or other properlylocated opening may be used.

The chiller should be installed in anindoor location where temperaturesrange from 4.5C to 43C.

Water CircuitsFlow Rate For normal water chillingduty, cooler and condenser flow ratesare permitted to any velocity levelbetween 1.0 m/s and 3.65 m/s). Flowshould be maintained constant at allloads. Refer to Table 3 for flow limits.

Pressure Drop For normal waterchilling duty, evaporator and condenserflow rates are permitted to any pressuredrop until 100 kPa. However, notably forbrine applications, pressure drops until150 kPa are acceptable. Refer to Table3 for flow limits.

Temperature Ranges For normalwater chilling duty, leaving chilled watertemperatures may be selected between3.3C and 18.9C for water temperaturedifferential between 1.6C and 11C.

Water Quality The practical andeconomical application of liquid chillersrequires that the quality of the watersupply for the condenser and cooler beanalysed by a water treatment specialist.Water quality may affect the performanceof any chil ler through corrosion,deposition of heat-resistant scale, orsedimentation or organic growth. Thesewill hurt chiller performance and increaseoperating and maintenance costs.Normally, performance may bemaintained by corrective water treatmentand periodic cleaning of tubes. If waterconditions exist which cannot becorrected by proper water treatment, itmay be necessary to provide a largerallowance for fouling, and/or to specifyspecial materials of construction.

General Piping All chilled water andcondenser water piping should bedesigned and installed in accordancewith accepted piping practice.

Chilled water and condenser waterpumps should be located to dischargethrough the chiller to assure positivepressure and flow through the unit.Piping should include offsets to provideflexibility and should be arranged toprevent drainage of water from the coolerand condenser when the pumps are shutdown. Piping should be adequatelysupported and braced independent ofthe chiller to avoid the imposition ofstrain on chiller components. Hangersmust allow for alignment of the pipe.Isolators in the piping and in the hangersare highly desirable in achieving soundand vibration control.

Convenience Considerations Toperform routine maintenance work, someor all of the following steps may be takenby the purchaser. Cooler and condenserwater boxes are equipped with pluggedvent and drain connections. If desired,vent and drain valves may be installedwith or without piping to an open drain.Pressure gauges with stop cocks, andstop valves, may be installed in the inletsand outlets of the condenser and chilledwater line as close as possible to thechiller. An overhead monorail or beammay be used to facilitate servicing.

Connections The standard chiller isdesigned for 1034 KPa design workingpressure in both the chilled water andcondenser water circuits. Theconnections (water nozzles) to thesecircuits are supplied with grooves forVictaulic couplings. Piping should bearranged for ease of disassembly at theunit for performance of such routinemaintenance as tube cleaning. All waterpiping should be thoroughly cleaned ofall dirt and debris before finalconnections are made to the chiller.

Chilled Water The chilled water circuitshould be designed for constant flow. Aflow switch must be installed in thechilled water line of every unit. Theswitch must be located in the horizontalpiping close to the unit, where thestraight horizontal runs on each side ofthe flow switch are at least five pipediameters in length. The switch must beelectrically connected to the chilled waterinterlock position in the unit controlcentre. A water strainer of maximum3.18mm mesh must be field-installed inthe chilled water inlet line as close aspossible to the chiller. If located closeenough to the chiller, the chilled waterpump may be protected by the samestrainer. The flow switch and strainerassure chilled water flow during unitoperation. The loss or severe reductionof water flow could seriously impair thechiller performance or even result in tubefreeze up.

Solid State Starter (SSS) coolingChilled water cooling of the SSS isrequired when entering condenser watertemperature exceeds 37,5C.

MODBUS (RTU) CommunicationProtocol Option.- Microgateway Board- for Standard ISN Panel

The Microgateway board is fitted on thechiller by the factory. The setting is madeby the factory.

With this option the chillers may becontrolled or monitored locally orremotely by any device that can processModbus (RTU) requests.


APPLICATION DATA (CONTINUED)Condenser Water The chiller isengineered for maximum efficiency atboth design and part-load operation bytaking advantage of the colder coolingtower water temperatures which naturallyoccur during the winter months.

Appreciable power savings are realizedfrom these reduced head conditions.Exacting control of condenser watertemperature, requiring an expensivecooling tower bypass, may not benecessary in all applications.

The minimum entering condenser watertemperature (C) is defined by thefollowing equation:

Min ECWT = LCHWT + 9 + [(% load/100)x (5.5 - full load condenser water T)]Where: ECWT = entering condenserwater temperature

LCHWT = leaving chilled watertemperature

At initial startup, entering condensingwater temperature may be as much as14C colder than the standby chilledwater temperature. Cooling tower fancycling will normally provide adequatecontrol of entering condenser watertemperature on most installations.

Multiple UnitsSelection Many applications requiremultiple units to meet the total capacityrequirements as well as to provideflexibility and some degree of protectionagainst equipment shutdown. There areseveral common unit arrangements forthis type of application. The MillenniumChiller has been designed to be readilyadapted to the requirements of thesevarious arrangements.

Parallel Arrangement

Chillers may be applied in multiples withchilled and condenser water circuitsconnected in parallel between the units.Assuming two units of equal size, eachwill reduce in capacity, as the loaddecreases to about 40% of the totalcapacity, at which point one of the unitswill be shut down by a sequence control.

Assuming chilled water flow to theinoperative unit is stopped by pumpshutdown and/or a closed valve, theremaining unit will pick up the totalremaining load and continue to reducein capacity as the load decreases. Theunit will cycle off on the low chilled watertemperature control when the loadreduces below minimum unit capacity.

The controls can maintain constant(0.28C) leaving chil led watertemperature at all loads.

If chilled water continues to flow throughthe non-operating unit, the chilled waterflowing through the operating unit willmix with the water leaving the non-operating unit to produce a commonwater supply to the load. Since controlof the operating unit is from its ownleaving chiller water temperature, thecommon temperature to the load will riseabove the full-load design temperature.This higher chilled water temperatureoccurs below 40% load when thedehumidification load in normal airconditioning applications is usually quitelow. In such instances, this temperaturerise will save additional energy.

The running time may be apportionedbetween both units by alternating theshut off sequence.

Series Arrangement

The chillers may be applied in pairs withchilled water circuits connected in seriesand condenser water circuits connectedin parallel. All of the chilled water flowsthrough both coolers with each unithandling approximately one-half of thetotal load. When the load decreases toabout 40% of the total capacity, one ofthe units will be shut down by asequence control. Since all water isflowing through the operating unit, thatunit will cool the water to the desiredtemperature.

Brine ApplicationsThe YN Screw Chiller, utilizing theindustrial screw compressor, is a goodmatch for the high head requirements oflow temperature brine applications. Thisis particularly true of thermal ice storagesystems, typically requiring 5.6C to 4.4C leaving brine temperatures. Thisperformance is enhanced with thestandard thermal storage control mode.

Particular attention must be paid to theapplication of two or more chillers withevaporators in parallel or series whenthe brine temperature is below 0C. Thebrine must not flow through theevaporator of the idle chiller, because itcan cause the condenser water tofreeze. A bypass or other type ofarrangement is required that shuts offflow to the idle evaporator. When unitsare applied in series with lead/lagcapability, the units should be identical.

Refrigerant Relief PipingEach chiller is equipped with pressurerelief devices. The purpose of the reliefdevices is to quickly relieve excesspressure of the refrigerant charge toatmosphere, as a safety precaution inthe event of an emergency such as afire.

They are set to relieve at an internalpressure of 2069 KPa and are locatedon the condenser, evaporator and oilseparator.

Each unit is also equipped with a rupturedisk which relieves the entire pumpingcapacity of the compressor if electronicsafeties fail, providing protection forproperty and personnel.

Sized to the requirements of applicablecodes, a vent line must run from therelief device to the outside of thebuilding. This refrigerant relief pipingmust include a cleanable, vertical-leg dirttrap to catch vent-stack condensation.Vent piping must be arranged to avoidimposing a strain on the chil lerconnections and should include oneflexible connection.

Sound and Vibration ConsiderationsA Millennium chiller is not a source ofobjectionable sound and vibration innormal air conditioning applications.Neoprene isolation mounts, supplied asstandard with each chiller, are perfectlyadequate for ground-floor installations.For upper-floor installation standard,level-adjusting spring isolator assembliesdesigned for 25mm static deflectionshould be used (available from York asan option).

YN chiller sound pressure level ratingswill be supplied on request.

Control of sound and vibrationtransmission must be taken into accountin the equipment room construction aswell as in the selection and installationof the equipment.

OPERATING LIMITATIONS TABLE 2

APPLICATION DATA (CONTINUED)Thermal InsulationNo appreciable operating economy canbe achieved by thermally insulating thechiller. However, the chillers coldsurfaces should be insulated with avapour barrier insulation sufficient toprevent sweating. A chiller can be factoryinsulated with 19mm or 38mm thickinsulation, as an option. This insulationwill normally prevent sweating inenvironments with dry bulb temperaturesof 10C to 32C and relative humidities

up to 75% (19mm thickness) or 90%(38mm thickness). The insulation ispainted and the surface is flexible andreasonably resistant to wear. It isintended for a chiller to be installedindoors and, therefore, no protectivecovering of the insulation is usuallyrequired. If insulation is applied to thewater boxes at the job site, it must beremovable to permit access to the tubesfor routine maintenance.

VentilationLocal and other related codes shouldbe reviewed for specific requirements.Since the chiller motor is air-cooled,ventilation should allow for the removalof heat from the motor.

The maximum flows have been calculated the 2 following limiting conditions: a maximum velocity of 3.65 m/s in the exchangepipes; a maximum pressure drop of 150 kPa in the circuit. When the maximum pressure drop is the limiting condition, thevalues are indicated with an asterisk.

MOTOR VOLTAGE FACTORS TABLE 4

Electrical ConsiderationsMotor Voltage Low voltage motors (upto and including 600 volts) are furnishedwith six leads.

Motor circuit conductor size must be inaccordance with National ElectricalCodes, for the motor full-load amperes(FLA). Flexible conduit should be usedfor the last several feet to the chiller inorder to provide vibration isolation. Table4 lists the allowable variation in voltagesupplied to the chiller motor. The unitnameplate is stamped with the specificmotor voltage and frequency for theappropriate motor.

Starters The chiller is available with afactory-mounted and wired YORK SolidState Starter for voltages up to 600 volts.Other types of remote mounted startersmay be used, supplied by others. Theseelectro-mechanical starters must besupplied in accordance with YORKStandard Specifications. This will ensurethat starter components, controls,circuits, and terminal markings will beapplicable for required overall systemperformance.

Controls A 115 volt, single phase, 50Hertz power supply must be supplied tothe chiller from a separate, fuseddisconnect or from a control transformerincluded as an option with electro-mechanical starters. No field controlwiring is required, when the YORK SolidState Starter is supplied.

Copper Conductors Only copperconductors should be connected tocompressor motors and starters.Aluminum conductors have proven to beunsatisfactory when connected to copperlugs. Aluminum oxide and the differencein thermal conductivity between copperand aluminum cannot guarantee therequired tight connection over a longperiod of time.

Capacitors Capacitors can be appliedto a chiller for the purpose of powerfactor correction. For Star-Delta Closed-Transition and Across-the-Line starters,the capacitors should be located on theload side of the starter. For YORK SolidState Starters, the capacitors must belocated on the line side of the starter.Capacitors are not recommended for usewith Star-Delta Open-Transition starters.The capacitors must be sized andinstalled to meet National ElectricalCodes and be verified by York.

Compressor Motor Power Supply Electrical power wire size to the chilleris based on the minimum unit ampacity.For Solid State Starters, this wiring isdone at the factory. For remote starters,National Electrical Codes defines thecalculation of ampacity, as summarizedbelow. More specific information onactual amperage ratings will be suppliedwith the submittal drawings.

Six-lead type of starting (Star-Delta)

Minimum circuit ampacity per conductor(1 of 6):

Ampacity = .721 x compressor motoramps.

ELECTRICAL DATAThree-lead type of starting

(Across-the-Line, Autotransformer andPrimary Reactor)

Minimum circuit ampacity per conductor(1 of 3):

Ampacity = 1.25 x compressor motoramps.

Fused Disconnect Switch The fuseddisconnect switch for the compressormotor starter must be sized inaccordance with National ElectricalCodes. Below 600 volts, the formulagenerally is:

Amp rating = 115% x amps of all loadson the circuit

This would include compressor motor,and may include control transformer.Refer to submittal drawings for specificcalculations for each application.

Ampacity on Line Side of Starter Min. Circuit Ampacity =

125% of Compressor. motor amps FLA+ of all other loads on the circuit

The only additional load on the circuitfor the chiller would be the controltransformer, unless they are supplied bya separate source.

Branch Circuit OvercurrentProtectionThe branch circuit overcurrent protectiondevice(s) should be a time-delay type,with a minimum rating equal to the nextstandard fuse/breaker rating above thecalculated value. It is calculated takinginto account the compressor motor ampsand may also include controltransformer. Refer to submittal drawingsfor the specific calculations for eachapplication.
