SelectionProcedure

This section describes the catalogselection of single-duct VAV terminalunits with specific examples. Acomputer selection program is alsoavailable to aid in selection of VAVterminal units.

Selection of single-duct VAV terminalunits can involve three elements:

• Air valve selection• Heating coil selection (if required)• Acoustics

Air Valve Selection

The wide-open static pressure andairflows are found in the performancedata section of the catalog. To select anair valve, locate the required designcooling airflow for your terminal unittype and find the smallest air valve sizethat has a pressure drop equal to orlower than the maximum wide-openstatic pressure requirement.

Selection Example—Cooling Only VCCF Terminal Unit

Design cooling airflow: 1700 cfmMaximum wide openAir pressure drop: 0.25 in. wgMinimum cooling airflow: 850 cfm

From the performance data charts,select a valve size 12, which has a wide-open static pressure drop of 0.01 in. wg

Check the minimum and maximum cfmdesired with the minimum andmaximum cfm allowed in the table inthe general data section. The maximumsetting of 1700 cfm is within theacceptable range. The desired minimumsetting of 850 cfm is acceptable for thecooling only box desired. Note that if anelectric reheat box was selected, theminimum cfm would be dependentupon the kW of the electric heater. (SeeElectric Heat Unit Selection.)

Heating Coil Selection (Ifrequired)First, determine the amount of heatrequired to meet space anddownstream duct heat losses from aload calculation.

Hot Water HeatSelect a hot water coil sufficient to meetthe design heat loss.

Example:VCWF, Hot Water Unit Heat, Size 12(See air Valve Selection)Heating airflow: 850 cfmHot water flow: 1.0 gpmDesign Heat Loss: Q =25 MBh

Select hot water coil from the coilperformance table in the PerformanceData section of the catalog.

Selection:A one-row coil is sufficient to meetdesign conditions. From the Hot WaterCoil Capacity Data of the PerformanceData Section, a one-row coil for a size12 air valve will operate at the aboveconditions as follows:

Coil Capacity: 25.17 MBhWater pressure drop: 0.72 ft WPD

Air pressure drop (APD) of the hotwater coil is included in the chartpreceding the hot water coilperformance data section.

APD = 0.35 in. wg

Electric HeatDetermine the kW required to meetzone design heat loss.

kW = MBh / 3.414

MBh = Design Heat Loss

Select the nearest available kW withvoltage and steps desired from theelectric heater kW guideline table in thePerformance Data section of thecatalog.

Example:VCEF, Electric Unit Heat, Size 12(See Air Valve Selection)Heating airflow: 850 cfmVoltage: 277/60/1 VACDesign Heat Loss: Q = 25 MBh

kW = Q/3.414

kW = 25/3.414

kW = 7.3

Selection:Select 7.5 kW from the electric heattable in the voltage and stagesrequired. The table shows theminimum cfm allowable for the kWselected. The static pressurerequirement is shown as 0.06 in. wgfor this example with a design coolingflow of 1700 cfm.

Check Leaving Air Temperature:

T is the primary entering airtemperature 55°F for this example.

Decide if leaving air temperature of82.8°F is satisfactory for yourapplication.

AcousticsThe acoustical data found in the"Performance Data" section of the VAVcatalog is used to make adetermination of the amount of noisethe terminal unit will generate. Locatethe table for the VAV terminal unit ofinterest. Sound power data and anequivalent NC level for an ARI 885-98transfer function is listed.

Example:VCCF, Cooling-Only Terminal Unit, Size10 (See air Valve Selection)Cooling Airflow: 1100 cfm

Maximum inlet staticpressure: 1.5 in. wg

Interpolation gives sound powerdata of:

LAT = 3414 x 7.51.085 x 850

+ 55 = 82.8

LAT = Q1.085 x CFM

+ T

The maximum NC level is NC-37. If themaximum NC level was exceeded, itwould have been necessary to reselectthe next larger unit size.

Computer SelectionThe advent of personal computers hasserved to automate many processesthat were previously repetitive andtime-consuming. One of those tasks isthe proper scheduling, sizing, andselection of VAV terminal units. Tranehas developed a computer program toperform these tasks. The software iscalled the Trane Official ProductSelection System (TOPSS).

The TOPSS program will take the inputspecifications and output the properlysized VariTrane VAV terminal unit alongwith the specific performance for thatsize unit.

The program has several requiredfields, denoted by red shading in theTOPSS screen, and many otheroptional fields to meet the criteria youhave. Required values includemaximum and minimum airflows,control type, and model. If selectingmodels with reheat, you will berequired to enter information to make

The NC level above is determined byusing either the catalog’s ARI 885-98(mineral fiber for radiated sound)transfer function for the conditionsshown in the acoustics table. Adifferent transfer function could beapplied as conditions dictate.

The user can select single-duct, dual-duct, and fan-powered VAV boxes withthe program, as well as most otherTrane products, allowing you to selectall your Trane equipment with onesoftware program.

The program will also calculate soundpower data for the selected terminalunit. The user can enter a maximumindividual sound level for each octaveband or a maximum NC value. Theprogram will calculate acoustical datasubject to default or user suppliedsound attenuation data.

Schedule ViewThe program has many time-saving features such as:

• Copy/Paste from spreadsheets like Microsoft® Excel• Easily arranged fields to match your schedule• Time-saving templates to store default settings

The user can also export the Schedule View to Excel to modify and put into a CADdrawing as a schedule.

Minimum Circuit Ampacity (MCA) Equation— MCA = heater amps x 1.25

Maximum Overcurrent Protection (MOP) Equation— MOP = heater amps— However since MOP ≤ MCA, then choose next fuse greater than MCA.— Units without electric reheat would use smallest fuse sizing.— Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.

Example–For MOP of Single-Duct UnitA model VCEF, electric reheat unit size 14 has 480/3 phase 15 kW electric reheat with 2 stages.15 kW – 480/3 heater 15 x 1000 = 18.06

480 x 1.73MCA = 18.06 x 1.25 = 22.58 amps. Since MOP ≤ MCA, then MOP = 25.

Torque is35 in-lb minimum and is non-springreturn with a 90-second drive time.Travel is terminated by end stops atfully-opened and -closed positions. Anintegral magnetic clutch eliminatesmotor stall.Direct Digital Controller—Themicroprocessor based terminal unitcontroller provides accurate, pressure-independent control through the useof a proportional integral controlalgorithm and direct digital controltechnology. The controller, named theUnit Control Module (UCM), monitorszone temperature setpoints, zonetemperature and its rate of change,and valve airflow using a differentialpressure signal from the pressuretransducer. Additionally, the controllercan monitor either supply duct airtemperature or CO2 concentration viaappropriate sensors. The controller isprovided in an enclosure with 7/8"(22 mm) knockouts for remote controlwiring. A Trane DDC zone sensoris required.DDC Zone Sensor—The UCMcontroller senses zone temperaturethrough a sensing element located inthe zone sensor. In addition to thesensing element, zone sensor optionsmay include an externally-adjustablesetpoint, communications jack for usewith a portable edit device, and anoverride button to change theindividual controller from unoccupiedto occupied mode. The override buttonhas a cancel feature that will return thesystem to unoccupied. Wired zonesensors utilize a thermistor to vary thevoltage output in response to changesin the zone temperature. Wiring to theUCM controller must be 18- to 22-awg.twisted pair wiring. The setpointadjustment range is 50–88ºF (10–31°C).Depending upon the features availablein the model of sensor selected, thezone sensor may require from a 2-wireto a 5-wire connection. Wireless zonesensors report the same zoneinformation as wired zone sensors, butdo so using radio transmittertechnology. Therefore with wireless,

wiring from the zone sensor to the UCMis unnecessary.Digital Display Zone Sensor withLiquid Crystal Display (LCD)—The digital display zone sensor containsa sensing element, which sends a signalto the UCM. A Liquid Crystal Display(LCD) displays setpoint or spacetemperature. Sensor buttons allow theuser to adjust setpoints, and allow spacetemperature readings to be turned on oroff.
