MATCHED COMPONENTS MAXIMIZE EFFICIENCY

Overall chiller efficiency cannot be determined by analyz-ing the theoretical efficiency of any one chiller component. It requires a specific combination of heat exchanger, compressor, steam turbine and steam condenser perfor-mancetoachievethelowestsystemsteamrate .YORKYST MAXE chiller technology matches chiller systemcomponents to provide maximum chiller efficiency under actual-notjusttheoretical-operatingconditions .

REAL-WORLD ENERGY PERFORMANCE

YORKpioneeredtheterm“Real-WorldEnergy”toillus-trate the energy-saving potential of focusing on chillerperformanceduringoff-designconditions .Off-designisnot only part load, but full load operation as well, with re-ducedenteringrefrigerantcondenserwatertemperatures

(ECWTs). This is where chillers operate 99% of the time, andwhereoperatingcostsaddup .

The YST MAXE chillers are the only chillers designedtooperateonacontinuousbasiswithcoldECWTandfull refrigerant condenser flow at all load points, taking full advantage of Real-World conditions . This type ofoperation benefits the cooling tower as well; reducing cyclingofthefanmotorandensuringgoodcoverageofthe cooling fill.

SINGLE-STAGE COMPRESSOR DESIGN AND EFFICIENCY PROVEN IN THE MOST DEMANDING APPLICATIONS

Designed to be the most reliable chillers we’ve ever made, YORKYSTMAXEcentrifugalchillersincorporatesingle-stagecompressordesign .Withfewermovingpartsandstraightforward, efficient engineering, YORK single-stage compressors have proven durability records in hospitals, chemical plants, gas processing plants, the U.S. Navy, andinotherapplicationswhereminimaldowntimeisacrucialconcern .

In thousands of installations worldwide, YORK single-stage compressors are working to reduce energy costs. High strength, aluminum-alloy compressor impellers feature backward-curved vanes for high efficiency. Airfoil shaped, pre-rotation vanes minimize flow disruption for the most efficient part load performance. Precisely po-sitioned and tightly fitted, they allow the compressor to unloadsmoothlyfrom100%tominimumloadforexcellentoperationinairconditioningapplications .

TAKE ADVANTAGE OF COLDER COOLING TOWER WATER TEMPERATURES

YORKYSTMAXEcentrifugalchillershavebeendesignedto take full advantage of colder cooling tower water temperatures, which are naturally available during most operatinghours .Considerableenergysavingsareavail-able by letting tower water temperature drop, rather than artificially holding it above 75°F (24°C), especially at low load, as some chillers require.

Each chiller is custom-matched to meet the individualbuildingloadandenergyrequirements .Alargenumberofstandardheatexchangersandpassarrangementsareavailabletoprovidethebestpossiblematch .

Itisnotpracticaltoprovidetabulatedperformanceforeachcombination, as the energy requirements at both full and part load vary significantly with each heat exchanger and passarrangement .Computerized ratingsareavailablethrough each YORK sales office. These ratings can be tailored to specific job requirements.

OFF-DESIGN PERFORMANCE

Sincethevastmajorityofitsoperatinghoursarespentat off-design conditions, a chiller should be chosen not

only to meet the full load design, but also for its ability to perform efficiently at lower loads and lower tower water temperatures . It is not uncommon for chillers with thesame full load tohaveanoperating cost differenceofover10%duetopart-loadoperation .

Part load information can be easily and accurately gener-atedbyuseofthecomputer .Andbecauseitissoimpor-tant to an owner’s operating budget, this information has now been standardized in the form of an Integrated Part Load Value (IPLV), and Non-Standard Part Load Value (NPLV). The IPLV / NPLV formulas, in accordance with ARI Standard 550/590 guidelines, much more closely track actual chiller operations. A more detailed analysis must take into account actual building load profiles, and local weather data. Part load performance data should be obtainedforeachjobusingitsowndesigncriteria .

WATER PIPING

Flow Rate - For normal water chilling duty, evaporator and refrigerant condenser flow rates are permitted at water velocitylevelsintheheatexchangerstubesofbetween3 ft/sec and 12 ft/sec (0.9 m/s and 3.7 m/s). Variable flow applications are possible, however, chiller selections mustbemadeusingawater velocitywithin the rangenoted above. Variable flow in the refrigerant condenser is not recommended, as it generally raises the energy consumption of the system by keeping the refrigerant condenser pressure high in the chiller. Additionally, the rateoffoulingintherefrigerantcondenserwillincreaseat lower water velocities associated with variable flow, raisingsystemmaintenancecosts .Coolingtowerstypi-cally have narrow ranges of operation with respect to flow rates and will be more effective with full design flow. Ref. Table 1 for flow limits.

Temperature Ranges - For normal water chilling duty, leaving chilled water temperatures may be selectedbetween 38°F (3.3°C) [36°F (2.2°C) with Smart Freeze enabled] and 70°F (21°C) for water temperature ranges between 3°F and 30°F (1.7°C and 16.7°C).

Weights

CALCULATING SHIPPING AND OPERATING WEIGHTS

YST shipping and operating weights can be calculated by adding up the appropriate breakdown weights provided in Tables 3 through 11. Shipments are broken down as follows:

Form 1 ShipmentChillershipscompletewithrefrigerantandoilchargeshippedwithunit .Shippingweightshouldincludeallcomponentsexcept steam condenser and exhaust trunk piping. Steam condenser and exhaust trunk ship loose to field for siteinstallation. Operating weight should include steam condenser, exhaust trunk piping and all water weight.

Form 2 ShipmentChiller ships complete, but without refrigerant or oil. Shipping weight should include all components except steam con-denser and exhaust trunk piping. Steam condenser and exhaust trunk ship loose to field for site installation. Operating weight should include steam condenser, exhaust trunk piping, all water weight plus refrigerant and oil.

Form 3 Shipment - BreakdownChiller ships in three major pieces, the shell package (evaporator and refrigerant condenser), driveline (turbine and compressor) and the steam condenser. Suction elbow and exhaust trunk piping ship loose. Shipping weight should bedivided accordingly into these three major assemblies. Operating weight should include all components, exhaust trunk piping, all water weight plus refrigerant and oil.

Form 7 Shipment – BreakdownChiller ships in four major pieces, the evaporator, refrigerant condenser (includes the oil reservoir), the driveline (turbine and compressor) and the steam condenser. Suction elbow and exhaust trunk piping ship loose. Shipping weight should be divided accordingly into these four major assemblies. Operating weight should include all components, exhaust trunk piping, all water weight plus refrigerant and oil.

GeneralNotesregardingcalculationofweight:1. Steam condenser package weights include single pumps only. When the dual pump option is ordered, use the weight adder to determine total package weight.2. Miscellaneous weight includes steam exhaust trunk piping, steam trunk expansion joint,waterconnectionpipingbetweenrefrigerantcondenseroutletandsteamcondenserwaterinletandweightformiscellaneouscomponents .3. Suction elbow ships loose for Form 3 or 7 breakdown shipments.4 .Refrigerantcondenserweightsincludeoilreservoirdryweights(shipswithcondenseron breakdown shipments).5. Mechanical fittings for victaulic connections are NOT included in York scope of supply. All fittings are provided by field.6. Weights reflect victaulic groove only. Flange weight, if applicable, must be added separately.7 .Weightsshownfor2passwaterboxesincludesweightofreturnhead .8 .Weightsshownfor1or3passwaterboxesarethetotalofbothboxes .
