VAV System OverviewSystem IntroductionIn a Variable Air Volume (VAV) system,air delivery volume varies directly withthe changing cooling or heating load,thus saving energy at part loadconditions. Another benefit that makesVAV a popular choice in HVAC designis its capability to control temperaturein multiple zones. Compared toconventional constant volume system,VAV system has multiple VAV terminalboxes each serving a zone controllingair flow to that zone and maintainingthe set-point temperature.Trane leads in VAV technology with itsinnovative range of VariTrane units(Single-duct and Fan-powered types)that are designed for diverseapplications and environments.Applications include office space,conditioning systems, VAV systemscan utilize the outdoor fresh air asmuch as possible during transitionalseasons, which not only saves energyconsumption, but also improves indoorair quality. It is estimated that over30% of the annual energyconsumption can be saved and10-30% of total equipment capacitycan be reduced by using VAV system.2. Improved Indoor Air Quality andComfortWith the integrated DDC control,VariTrane VAV terminal units can keeproom temperature and air volumewithin the pre-set range per actualcooling or heating load requirementand enhance control accuracy of theterminal unit. It allows roomtemperature to be adjusted perapplication requirement. Supply air ofVAV system can be remote andcentralized controlled to improve thesystem efficiency and room air quality.hospitals, hotels, retail stores, mallsand educational facilities. VariTraneprovides the most reliable and flexibleproducts available, further enhancedby Trane DDC controls inimplementing systems-level controlstrategies like ventilation reset andStatic Pressure Optimization toimprove systems performance andefficiency.3. Reliable Operation, SimpleConstructionVAV system is an all-air system. Thereis no water piping passing through theceiling of the room, which can avoidproblems such as condensation, waterleakage and bacteria breeding whichmay happen in the fan coil system. Inaddition, VariTrane VAV boxes havesimple casing construction, whichmakes installation simple and easy.4. Flexible SystemRenovation always occurs in modernbuildings. By using flexible ductconnection, modification of VariTraneVAV terminal unit position can be doneaccording to the room partition andrequirement with minimum fieldmodification cost, labor and time.5. Compatible SystemVAV systems can be integrated withother air conditioning systems tooptimize performance efficiency. Forexample, when integrated with icestorage system, the application of coldair distribution can reduce the initialinvestment of ice storage systemeffectively; when integrated with heatpump system it can reduce the initialinvestment, reducing the noise levelby installing several water heat pumpsin central location and avoid costlyinstallation of heat pump at each floor.6. Easy to get integrated withBuilding Automation (BA) systemVAV systems can be integrated to BAsystem via DDC control. Systemoptimization and monitoring of thewhole system can be achieved bycomputerized control.VAV System StructureA typical VAV System consists of:1.Air handling units2.Air duct system3.VariTrane VAV terminal nuitVAV System Features andBenefitsVAV systems have the followingfeatures and benefits:1. Economical OperationVAV systems can change the supplyair volume according to the coolingand heating load variation to enablethe cooling, heating capacity and fanpower to meet actual loadrequirement.

VAV System OverviewSystem Control IntroductionWorking station(Optional)The VariTrane VAV box can beconnected to Trane’s BuildingAutomation System through two typesof control systems.Tracer SystemIn Tracer, the work station using TracerSummit software monitors the wholesystem and has many functions suchas operating parameter setting, dataacquisition, alarming, reports, clock,etc. The Building control Unit (BCU)provides control logic for the wholesystem and coordinates the operationbetween equipment level controllerssuch as MP581 and VAV controllers.VAV controllers are connected to eachother by using RS485, and thenconnected to BCU. The whole controlsystem structure is simple, compatibleand designed to accommodate futureextension requirements.BCUDial-up connection orEthernet/IP connectionVariTrane VAVterminal unitVariTrane VAVterminal unit-- Zone sensorMP581AHUZone sensorVAV systemWork station(Optional)In addition, using LonTalk DDCcontrollers, VariTrane VAV terminalunits can be connected to third partycontrol systems which have LonTalkprotocol.TrackercontrollerDial-up connection orEthernet/IP connectionVariTrac CCPTracker systemIn Tracker, the work station isconnected to a Tracker controller. Itacquires equipment status, systemdata information, control commandand monitors the system equipment.The Tracker controller provides controllogic for the whole system. Itcoordinates the rooftop equipment(Voyager) & VariTrane VAV terminalunit control through the CCP (centralcontrol panel). One Tracker controllercan be connected to several CCPs,and each CCP is connected to onerooftop unit (Voyager) and severalVariTrane VAV boxes. Intercommunication is possible betweenCCPs. All equipment connections inthe system are PnP (plug and play),making it convenient for installationand application.VariTrac CCPVoyager III VAV RTUVoyager III VAV RTUVariTrane VAVterminal unitVariTrane VAV VariTrane VAVterminal unit terminal unitVariTrane VAVterminal unit---- Zone sensorZone sensorVAV system4Zone sensorZone sensorVAV system

VariTrane VAV Terminal UnitOverviewVAV Terminal UnitClassificationA VAV terminal unit controls the airvalve opening and regulates the airvolume in the room by measuring thetemperature difference between roomand set point. There are two basicworking principles of a VAV box:pressure-dependent andpressure-independent.A pressure-dependent VAV controlscheme uses the space temperaturesensor to control the position of themodulating device directly. The actualAir intakeVAV terminalAir outgoingAir intakeAir outgoingFlow ringAir valveController/air valve drivePressure-independent controlincreases the stability of airflow controland allows minimum and maximumairflow settings to become actualairflows rather than physical positionsof the modulation device. It is clearlymost popular in all VAV terminal unitcontrols.In contrast, a pressure-independentVAV control scheme controls the actualvolume of primary air that flows to thespace. An airflow-measuring device onthe terminal unit makes it possible.The position of the modulation deviceVAV terminalTemperature sensoris not directly controlled and isbasically a by-product of regulating theairflow through the unit. Because theairflow delivered to the space isdirectly controlled, it is independent ofinlet static pressure.airflow delivered to the space dependson the duct system static pressure atthe inlet of the terminal unit. Althoughthe space temperature sensor willcontinually correct the position of themodulating device, the response canbe sluggish and cause unacceptabletemperature variations within thespace.Air valveController/air valve drive/differential pressure transmitterPressure-dependentTemperature sensorPressure-independentThere are three basic types ofVariTrane VAV terminal units,Single-duct (without fan), SeriesFan-Powered and ParallelFan-Powered.Single-ductSeries fan-powered5Parallel fan-powered
