_____________________________________________________________________________________INTRODUCTION AND OVERVIEWWORLD LEADER IN OIL-FREE CHILLER EFFICIENCYThe PowerPax and <strong>SMARDT</strong> companies joined forces in 2005 to merge their global operationsin engineering, development, testing and certification, supply chain, technical services andcustomer support.PowerPax, based in Melbourne, Australia, was founded in 2000 by a team of HVAC industryexperts, to specialize in high-efficiency shell-and-tube heat exchangers and their optimization inoil-free centrifugal chillers.<strong>SMARDT</strong>, based in Montreal, Quebec, was founded in 2005 by a team of Turbocor veterans, toproduce chillers which optimized the energy efficiency potential of the Turbocor compressortechnology.The <strong>SMARDT</strong> Chiller Group now has well over 1800 operating chiller installations across theworld, all delivering high reliability, outstanding part-load efficiencies, and the overall lowest costof ownership in the market today. Achieving these goals consistently remains the Group’s corepurpose, and clearly differentiates it from competitors with conventional machines.CERTIFICATIONAll <strong>SMARDT</strong> chillers are ETL listed, have lifetime electrical safety coverage, and incorporateevaporators and condensers that fully comply with ASME pressure vessel codes.<strong>SMARDT</strong> chiller energy efficiency performance is certified according to AHRI standard 500/590(ref: www.ahrinet.org). IPLV performance always far exceeds the minimum levels set out byASHRAE standard 90.1, CSA 743, Eurovent, Australia’s MEPS, and other governing bodies.STRONG LEED CONTRIBUTIONUse of <strong>SMARDT</strong> chiller technology can significantly contribute to achieving Leadership inEnergy & Environmental Design (LEED) certification for a building, be it in existing buildings ,core and shell constructions, or new construction, because it can help win critical points in theEnergy & Atmosphere category. Market research by the U.S. Green Building Council (USGBC)finds that the streamlined LEED process is second only to rising energy costs as a driver forstronger adoption of green building practices and the transformation of the built environment tosustainability. <strong>SMARDT</strong> is a member of the USGBC.STRONG SUPPORT FOR THE EPA RESPONSIBLE USE VISIONThe EPA’s Responsible Use vision, encourages manufacturers, system designers, and owners,to invest in products and technologies which document sustainability of the highest efficiencies,in tandem with the lowest emissions. <strong>SMARDT</strong> is a strong supporter of the vision and of theEPA.________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 4


Compressor <strong>Tech</strong>nology_____________________________________________________________________________________COMPRESSOR TECHNOLOGY<strong>SMARDT</strong> chillers optimize the benefits ofthe revolutionary Danfoss Turbocor oil-freecentrifugal compressor technology. TheTT300 compressor delivers 60 to 90 TR andthe TT400 delivers 120 to 150 TR.Advanced electronics mean that mechanicalforces can be managed with extraordinarytolerances and achieve a very high degreeof reliability.The integral 2 stage centrifugalcompressor and shaft is levitated utilizingstate of the art magnetic bearingtechnology, which positions and adjusts theassembly automatically, 120 times perrevolution.Cutaway view of the advanced oil-less magnetic bearing technology of the Danfoss TurbocorCompressor used in the <strong>SMARDT</strong> range of Chillers.The one combined moving part in the <strong>SMARDT</strong> Chiller – the magnetically levitated 2 stagecentrifugal compressor and shaft of the Turbocor Compressor.________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 5

<strong>SMARDT</strong> Product Benefits_____________________________________________________________________________________A QUANTUM LEAP IN ENERGY EFFICIENCYAll <strong>SMARDT</strong> chillers, whether water-cooledor air-cooled, are designed to optimize theperformance of the highly efficient DanfossTurbocor oil-free centrifugal compressor.Oil-free magnetic bearing technology andvariable-speed drives, deliver better IPLVefficiencies than conventional oil-lubricatedcentrifugal, reciprocating, scroll, and screwcompressors. They are also high-speed – upto 48,000 rpm, very compact, very quiet,rugged, and reliable. The Power Factor is ahigh .92.Proprietary magnetic bearings replaceconventional oil lubricated bearings, whicheliminate high friction losses, mechanicalwear, and high-maintenance oilmanagement systems, to deliver chillerenergy savings of 35 percent and more overconventional chillers, while ensuring longtermreliability. Over 75,000 magneticbearing machines are operating in the field,mainly in high-end vacuum pumps and CNCspindles - any innovation risk having beenlong overcome.Heat Transfer Optimization Through Oil-Free DesignThe well-known ASHRAE study (researchProject 361) concluded that typicallubricated chiller circuits show reductions indesign heat transfer efficiency of 15-25%,as lubricant accumulates on heat transfersurfaces, denatures and blocks normalthermodynamic transfer processes.Logically, no oil in your chiller means no oilcontamination over time, so designefficiency is maintained effortlessly.Extraordinary Soft-Start EfficiencyThe compressor’s power electronics, furtherenhanced by <strong>SMARDT</strong>’s chiller controllers,require only 2 amps for start-up, comparedwith 500-600 amps for conventionalmachines. This means further savings forowners, who can reduce maximum powerloads and reduce backup generator size,cost and capacity.Turbocor’s one main moving part (rotorshaft and impellers) is levitated duringrotation by a digitally-controlled magneticbearing system. Position sensors at eachmagnetic bearing, provide real-timefeedback to the bearing control system at120 times each revolution, thus ensuringconstantly centered rotation.Key benefits of <strong>SMARDT</strong> chillers can besummarized as:Heat transfer optimization throughoil-free designExtraordinary soft-start efficiencyRugged & built-in defense againstpower failureHFC-134a ozone friendly refrigerantSignificant noise reductionSpectacular energy cost savingsImproved part load efficienciesRugged & Built-in Defense Against PowerFailureEach compressor has a bank of capacitorsfor energy storage and to filter DC voltagefluctuations. In case of a power failure, thecapacitors provide continuity power to thebearings to keep the shaft levitated,allowing the motor to turn into a generatorand to power itself down to a stop. Extendedlife testing confirms the system’sremarkable durability.HFC-134a Ozone Friendly RefrigerantR134a has no ozone depletion potential andno phase-out schedule under the MontrealProtocol; it has an A1 rating under ASHRAEstandard 34 (no flame propagation, lowertoxicity). Positive pressure chiller designs(compared with negative pressure designs________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 8


<strong>SMARDT</strong> Product Benefits_____________________________________________________________________________________using R123, for example) enhancesustainable performance, as neither air ormoisture can leak into the chiller. No purgeunit is required – a further saving. LiquidR134a refrigerant is used in <strong>SMARDT</strong>chillers to cool critical electronic andelectromechanical components, to assuremaximum efficiency and safe operation.Significant Noise ReductionVery low sound and vibration levels areachieved, because there is no physicalcontact between moving metal parts,eliminating the need for expensiveattenuation. Testing of <strong>SMARDT</strong> watercooled chillers, with reference to AHRIstandard 575, yeilds readings as low as77dBA at 1 meter.Spectacular Energy Cost SavingsCompared with a new screw chiller,<strong>SMARDT</strong> IPLV energy efficiency is routinelymore than 32% better. Compared with olderlubricated reciprocating, screw, scroll, orcentrifugal chillers, year round energysavings with <strong>SMARDT</strong> chillers can be aspectacular 50% and more. Under AHRIconditions, <strong>SMARDT</strong> IPLV performance canbe as low as .33 kW/TR while part-loadefficiency can be under .30 kW/TR.Improved Part Load EfficienciesThe graph below (data source: AHRI 2005)shows very simply that a wide range of largeUS cities all demand the vast bulk of theirchiller operations at part load – enablingmuch lower operating costs with a <strong>SMARDT</strong>oil free chiller, compared with a lubricatedalternative.________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 9


Product Description____________________________________________________________________________________GENERAL DESCRIPTIONThe <strong>SMARDT</strong> range of chillers offer thesmallest footprint, the quietest operationand some of the highest operatingefficiencies on the market.<strong>SMARDT</strong>’s <strong>Water</strong>-<strong>Cooled</strong> centrifugal chillerdesign consists of a shell and tubeevaporator, shell and tube condenser, twinturbinecentrifugal compressor(s),compressor controller(s), hot gas bypassvalves, refrigerant level sensors, electronicexpansion valves, interconnectingrefrigerant piping, and safety features suchas triple freeze protection. All <strong>SMARDT</strong>chillers are designed to optimize theperformance of oil-free centrifugalcompressors from Danfoss TurbocorCompressors Inc.The chiller set is a packaged unit, requiringconnection to the chilled water circuit, mainelectrical supply, and integration with thebuilding automation system (BAS) ifapplicable. The following protocols areavailable on <strong>SMARDT</strong> Chillers for BASsystems: LON, BACNET, BACNET/IP, N2,and MODBUS/IP, and these interfaces areusually installed inside the <strong>SMARDT</strong> maincontrol panel.<strong>SMARDT</strong> chillers deliver a high level ofreliability, outstanding part-load efficiency,and the lowest overall cost of ownership onthe market.The above standard design 350 TR water-cooled chiller uses a flooded shell and tubeevaporator with shell and tube condenser to achieve an approach of 1 deg. K, allowing highIPLV________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 10


Product Description____________________________________________________________________________________<strong>SMARDT</strong> WATER COOLED CHILLER RANGE60 TR to 900 TRLowest Lifetime Operating Costs<strong>SMARDT</strong> works hard to minimizecomplexity in chiller design and operation,and <strong>SMARDT</strong> simplicity is reflected in lowproduct operating costs. The thinking makessimple sense: no oil, flooded shell-and-tubeevaporation, soft start, low powerconsumption, low maintenance costs andhigh reliability, with only one main movingpart.<strong>SMARDT</strong> field reliability has beenoutstanding, and not surprising when oneconsiders that some 80% of all chillerproblems in the field are due to failures incompressor oil return. And <strong>SMARDT</strong> chillersuse no oil.The growing fraternity of turbocor-trainedengineers and technicians often suggeststhat total maintenance costs for oil-freechillers run at well under half the costs oftraditional lubricated chillers.ServiceabilityAlways important in minimizing operatingcosts, is ease of serviceability. Serviceaccess is swift and simple with <strong>SMARDT</strong>chillers, as is access to operating historythrough remote monitoring. Operatinghistory, and compressor and chiller setpoints, are all accessible remotely bytrained and authorized service personnel.Simple BAS IntegrationIntegration with Modbus, Bacnet andLONworks building management systems isstandard, as is connectivity with mostindustry-standard protocols.Custom Design and Problem Solving<strong>SMARDT</strong> design engineers are alwaysready and willing to resolve particularequipment design challenges. For example,high-efficiency heat recovery and freecoolingapplications can all be customdesigned and supplied competitively, andcorrosion protection and other options arealso available.RedundancyThe use of multiple compressors allows forbuilt-in redundancy safeguards. <strong>SMARDT</strong>’sredundancy potential can offer systemdesigners unique opportunities to eliminatemultiple chillers, multiple controls, andmultiple pumps, thus bringing furthersavings for owners.Multiple compressors also allow systemdesigners to save on low-load or ponychillers, because with a VFD integrated intoeach compressor control, a chiller whichuses multiple compressors can be efficientlydriven right down below 10% or even 5%load.________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 11

Operation_____________________________________________________________________________________DESCRIPTION OF OPERATIONWATER COOLED CHILLER CYCLEControls – Cooling Cycle Operation:76When the <strong>SMARDT</strong> chiller control system is setto “HVAC_COOL” mode, indicating the chiller isto be used to control the leaving chilled watertemperature (LCWT) to a desired value, thefollowing description of operation is true:5EVAPORATOR DESCRIPTIONWhen the chiller is operated in cooling mode, thecondensed liquid refrigerant exits the electronicexpansion valve (4) Figure 10, and enters thebottom of the flooded evaporator, where it isevenly dispersed along the length of theevaporator by the use of a distributor plate (3).Liquid refrigerant inside the evaporator at lowpressure then makes contact with the coppertubes that the building’s water runs through,exchanges heat to the refrigerant, and vaporizesit (2) at the suction pressure of the compressor(1). As a result of the lower density of the vaporand the suction of the compressor, the vaporizedrefrigerant gas is then drawn to the top of theevaporator through the mist eliminators (5). (Misteliminators inhibit minute liquid particlesentrained in the vaporized refrigerant, fromentering the compressor). Passing through the(pre-rotation) inlet guide vanes (6), the vaporizedrefrigerant then enters the compressor inlet (7),where the angle of incidence of the refrigeranthitting the first stage impeller, is altered, therebyallowing a higher compression efficiency for agiven compressor rotor speed.Figure 10: Evaporator Refrigerant FlowCOMPRESSOR DESCRIPTION3<strong>SMARDT</strong> oil free chillers exclusively useTurbocor variable speed magnetic bearingcompressors (Figure 11) on all chillers. All of theTurbocor compressors are a two stage design,meaning the compression of the vaporrefrigerant takes place through two impellers.Figure 11: Turbocor Compressor - ExternalViewThe refrigerant enters the suction side of thecompressor as a low-pressure, low-temperature,super-heated gas - ref Figure 12, (1). The________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 39


Operation_____________________________________________________________________________________refrigerant gas passes through a set ofadjustable inlet guide vanes (IGV) (2) that areused to control the compressor capacity at lowload conditions.The first compression element that the gasencounters is the first-stage impeller (3), and thecentrifugal force produced by the rotatingimpeller results in an increase in both gasvelocity and pressure. The high-velocity gasdischarging from the impeller is directed to thesecond stage impeller (4) through de-swirl vanes(5). The gas is further compressed by thesecond stage impeller and then dischargedthrough a volute (6) via a vane-less diffuser (7).(A volute is a curved funnel increasing in area tothe discharge port. As the area of the crosssectionincreases, the volute reduces the speedof the gas and increases its pressure.) Fromthere, the high-pressure/high temperature gasexits the compressor at the discharge port (8).368Figure 13: Pressure v EnthalpyCapacity control on <strong>SMARDT</strong> chillers isachieved by varying the speed, inlet guide vaneposition, and number of operating compressors.Figure 14 provides a graphical representation ofthe centrifugal compressor’s response todemand and operating conditions.160 CInlet Guide Vane + Hot gas + Speed Control4275Figure 12: Turbocor Compressor Cross SectionCondensing Temperature (˚C)50 C40 C30 C20 CIGVControl+SpeedControlRotatingSpeedControl Only20%40%60%80%100%Refrigerating Capacity (%)Figure 14: Graphic Representation of CapacityControl________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 40


Operation_____________________________________________________________________________________CONDENSER DESCRIPTIONSuperheated refrigerant from the compressorenters at the top of the condenser barrel where itis dispersed by a deflection plate. As therefrigerant is moving around the tubes in thecondenser, heat is being constantly removedfrom the refrigerant and dissipated to the coolingwater that is moving through the condensertubes.HOT GAS VALVE CONTROLThe hot gas valve provides the followingfunctionality:Capacity control at low load.Assisted pressure ratio relief for startingnew compressors.Head pressure relief for heat pump andair cooled chillers operating above designconditions.It should be noted that the hot gas capacitycontrol of <strong>SMARDT</strong> air cooled chillers, only takesplace when the last compressor is operating.The chiller control system makes best use ofcompressor staging before resorting to hot gascontrol. Under normal air conditioning loadswhere the outside air temperature and the heatload applied to the chiller are closely related, it isnot uncommon for the hot gas capacity controlvalve never to be used.Assisted Pressure Ratio ReliefMajor reasons for requiring pressure ratio reliefwhen turning on one or more additionalcompressors within a refrigerant circuit wherecompressors are already operating, are:• To avoid rapid rotor displacement - whichis an inherent weakness of all centrifugalcompressors which do not incorporatepressure ratio unloading.Low Load Capacity Control FunctionalityHot gas control of leaving water temperature(LWT) is a last resort method of control whenspeed control and inlet guide vane control is nolonger an option. The hot gas valve control usesthe compressor’s IGV% surge. Choke and actualrpm determine when to use the hot gas valve forcapacity control.The set point for the hot gas control is adifferential temperature below the leavingtemperature set point. By using a differentialtemperature, the hot gas control set pointautomatically adjusts with a change in supplytemperature set point for the chiller, such that itis easy to implement alongside set point resetstrategies.As the diagram in Figure 14 shows, the hot gasvalve is only used once the compressors haveused up all speed and IGV control envelopes. Ifthe chiller’s capacity must be increased, and thehot gas valve is in the open position, the valvewill close before adjustment is made forincreased compressor demand.To reduce the potential of rotatingcomponent damage.High dynamic forces can impacttraditional bearing technologysignificantly. With the incorporation of therevolutionary magnetic bearing designused in the Turbocor compressor on<strong>SMARDT</strong> chillers, the potential forrotating component damage is greatlyreduced, in that shutdown can occurbefore any surface impact takes place.• Instability, as the compressor overcomesthe system pressure and begins to openthe discharge check valve.The danger of holding ramp up conditionswithout flow, for an extended period oftime:– All energy transferred to thecompressor, has no outlet, andresults in high internaltemperatures.– Large sudden amperage spikeson the inverter can be dangerous,________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 41


Operation_____________________________________________________________________________________Control Strategydue to low thermal inertia on InertGate By-polar Transistors (IGBT).The higher the head that must beovercome, the higher theamperage spikes.The assisted hot gas bypass start up is enabledwhenever the chiller enters the “STAGE UP”mode, and the pressure ratio calculated from thehighest discharge pressure and lowest suctionpressure of all compressors online, is above aconfigured limit default pressure ratio of 2.2.If hot gas pressure ratio assistance is required,the hot gas valve is forced open at 1% persecond, until the pressure ratio is reduced belowthe limit at which the next compressor is startenabled. Once the new compressor has startedand is running within 10% of the speed of theother compressors, the hot gas valve is closedslowly at a rate of 0.5% per second.Return water controlOccasionally, instead of supplying chilled watercontrol, <strong>SMARDT</strong> chillers are selected to providereturn water temperature control in a plant.Return water temperature control allows theleaving chilled water set point to automaticallyfloat with the actual building load. Runninghigher leaving chilled water temperaturespermits a higher chiller performance – anefficiency increase of approximately 3% per0.5°C (1°F) increase in set point is possible (ref.Figure 15 - Power Consumption v Load graphshown below).Selecting “HVAC_RET” mode on the chiller’sgraphical touch pad interface will enable controlfrom the return water temperature. All alarm andfault trip points are active in this mode, and extracare must be taken when selecting a returnwater temperature to run, to avoid driving thechiller into low suction pressure or low leavingchilled water faults. <strong>SMARDT</strong> suggests a setpoint of 10°C (50°F) to 15.5°C (60°F).Effect of Increased leaving chilled water temperature set point, on chiller performanceExample made with a 3 compressor water cooled chiller0.70.60.5kW/Ton0.444 Leaving46 Leaving48 Leaving50 Leaving0.30.20.10% 20% 40% 60% 80% 100% 120%% Chiller LoadFigure 15: Power Consumption v Load________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 42


Chilled <strong>Water</strong> System_____________________________________________________________________________________CHILLED WATER SYSTEMEVAPORATOR WATER CIRCUITSChiller performance and efficiency can beadversely affected by contaminants in thewater circuits, and such contaminants couldimpede or block the flow of water throughthe circuit or reduce the performance of theheat exchanger.Strainers should be located on the inlet sideof the evaporator, return water to the chillermust be connected to the lower connectionof the evaporator, and all external waterpiping must be cleaned or flushed beforebeing connected to the chiller set.<strong>Water</strong> circuits should be arranged so thatpumps discharge through the evaporatorand are controlled as necessary, to maintainessentially constant chiller water flowsthrough the unit at all load conditions.To ensure the chiller’s performance andlongevity, air must be purged from bothwater boxes on the evaporator, and from theentire water circuit.CHILLED WATER PUMPSMake all connections prior to filling withwater. Run a preliminary leak check beforeinsulating the pipes and filling with water.<strong>SMARDT</strong> recommends consultingauthorities in order to be compliant withlocal building codes and safety regulations.Additional considerations, as follows, shouldbe made when designing the piping system:All piping systems should includetemperature and pressure measuresat the evaporator. Make theseconnections prior to filling with water.<strong>Water</strong> pressure should bemaintained throughout the system.Install regulating valves orcomparable pressure maintenancedevices.The piping system should bedesigned with a minimum number ofelevation and directional changes inorder to minimize system pressuredrop.To prohibit debris from entering thepump, a strainer should be installedat the water supply line, and aheadof (before) the pump.Piping made to and from the chillerwater connections and pressurerelief valves, must be made in sucha way that weight and strain isremoved from the chillerconnections. All chilled waterpiping attached to chillerconnections, should be adequatelyinsulated. Strainers with 20 meshfilters, should be installedupstream of the evaporator .Adequate valving should be suppliedto permit draining of water from theevaporator.Install vibration eliminators to reducevibration transmission to thebuilding.Install air valves at the system highpoints and drain valves at thesystem low points. Additionally,shutoff valves should be installed forunit servicing.________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 43


Chilled <strong>Water</strong> System_____________________________________________________________________________________Protect water from freezing byinsulating water piping. Ensure thereis a vapor barrier on the outside ofthe insulation, in order to protectfrom pipe condensation within theinsulation.Note: If glycol or propylene is added forfreeze protection, this will cause a pressuredrop, which may then result in the loss ofperformance. Only use glycol with factoryapproval.WATER VOLUMEWhen designing the chilled water system,consider:The minimum cooling load.The minimum plant capacity during alow load period.The desired cycle time for thecompressor.If the chiller plant has a reasonableturndown, the water volume shouldbe two to three times the chilledwater gpm flow rate. If the systemcomponents do not provide therequired water volume, add astorage tank.1. That water flow shall not be alteredat a rate greater than 10% perminute.2. That the water flow rates shall notexceed the maximum and minimumflows detailed in the chiller selectionsheet.Variable speed pumping is a design featureof the <strong>SMARDT</strong> water-cooled chiller, whichreduces the water flow through theevaporator as the load decreases. Thisfeature will function successfully if thedesign and minimum flow rates are notexceeded. Check individual rating sheets formaximum and minimum flow rates.OPERATING LIMITSMaximum standby ambienttemperature = 54 C (130 F)Maximum operating ambienttemperature = 41 C (105 F)Minimum operating ambienttemperature (standard) = 3 C (38 F)Minimum operating ambienttemperature (operational lowambientcontrol) = -10 C (14 F)VARIABLE WATER FLOWA large range of <strong>SMARDT</strong> chillers are wellsuited to installations where the chilledwater and condenser water flow rates arechanged in the chiller, relative to theinstantaneous building load and outdoorconditions. When applying <strong>SMARDT</strong> chillersto variable volume (variable speed)pumping applications, the designer mustmake sure <strong>SMARDT</strong>’s design parametersare met as follows:Leaving chilled water temperature(LCWT) = 3 C to 16 C (38 F to60 F)Operating ΔT = 3K to 9K (6 F to16 F)Maximum operating inlet fluidtemperature = 24 C (76 F)________________________________________________________________________<strong>SMARDT</strong> CHILLER GROUP.TD - 0080 44

Priorto starting the unit, and to ensure adequatewater flow to the evaporator, it is necessaryto install a flow switch for the chilled watersystem. A flow switch will guard againstpossible evaporator freezing, should waterflow be interrupted. The flow switch is to befield installed in the chilled water piping andwired to the control panel by the installationcontractor.HIGH PRESSURE & LOW PRESSURESWITCHESLP: 179 kPa (26 psig) (≈ -1.7 C / 29 F),reset at 345 kPa (50 psig) (≈ 12.2 C / 54 F),(installed on the evaporator, except for lowambient/glycol applications, where the LPswitch is not installed).RELIEF VALVESEnsure relief valves vent outside a buildingin accordance with national safetyregulations and jurisdictional requirements.Concentrations of refrigerant in enclosedspaces can displace oxygen and lead toasphyxiation.

Chilled <strong>Water</strong> System_____________________________________________________________________________________All pressure relief valves on <strong>SMARDT</strong>chillers have been sized, selected andsupplied in accordance with ASHRAE 15and the ASME unfired pressure vesselcode. All discharge ratesare certified by the National Board of Boilerand Pressure Vessel Inpectors.RELIEF VALVE APPLICATIONCommon Header. ASHRAE 15 section9.7.8.4 allows for multiple relief devices (onthe same or multiple units) to be connectedinto a common line or header. The sizing ofthe common discharge header and ventpiping for relief devices - expected tooperate simultaneously - shall be based onthe sum of their outlet areas, with dueallowance for the pressure drop in alldownstream sections andThe ASHRAE 15 Safety Standard forRefrigeration Systems provides guidelinesfor sizing refrigerant relief valves and ventpiping. Without attempting to provide acomplete and thorough interpretation, thisdocument provides the necessary data toproperly determine piping requirements.VENT LINE SIZINGPiping. ASHRAE 15-2004, Section 9.7.8outlines acceptable relief piping locationsand sizing. Summarized, the relief pipingshould vent R-134a refrigerant at least 15feet above ground level and at least 20 1 feetfrom any window, ventilation opening, orbuilding exit. The discharge piping shouldprevent a discharged refrigerant from beingsprayed directly on personnel and preventforeign material or debris from entering thepiping. Additionally, discharge piping for afusible plug or rupture disc shall haveprovisions to prevent plugging the pipe inthe event of a discharge by the plug or disc.As indicated in <strong>SMARDT</strong> InstallationInstructions (Form 160.73-N1), each ventline must contain a dirt trap in the verticalsection to allow collection and removal forany stack condensation or debris. Thepiping MUST be arranged to avoid strain onthe relief valves – <strong>SMARDT</strong> recommendsthe use of a flexible connector.
