SelectionProcedure

This section describes the elementsand process required to properly selectparallel fan-powered VAV terminals,and includes a specific example. Theselection procedure is iterative innature which makes computerselection desirable.

Selection of fan-powered VAVterminals involves four elements:

�Air valve selection�Heating coil selection� Fan size and speed selection�Acoustics

Air Valve Selection

Provided in the performance datasection of the catalog is the Wide-OpenAir Pressure Drop vs. Airflow curve. Toselect an air valve, locate the requireddesign cooling airflow and find itsvertical intersection with the smallestair valve size that has air pressure dropequal to or lower than the maximumwide-open air pressure droprequirement.

Heating Coil Selection

Supply Air TemperatureThe first step required when selecting aheating coil is to determine the heatingsupply air temperature to the space,calculated using the heat transferequation. Air temperature difference isdefined as the heating supply airtemperature to the space minus thewinter room design temperature. Thezone design heat loss rate is denotedby the letter Q. Supply air temperatureto the space equals the leaving airtemperature (LAT) for the terminal unit.

Coil Leaving Air TemperatureOnce the terminal unit LAT isdetermined, the heating requirementsfor the coil can be calculated. Theleaving air temperature for the coil of aparallel fan-powered terminal unitvaries based on the type of unitinstalled heat being selected.

Electric coil LAT equals terminal unitLAT because the coil is located on theunit discharge. Hot water coils,however, are located on the enteringair side of the fan. In this case, coil LATis calculated using a mixing equation.Given the unit heating airflow and LAT,minimum primary airflow at its supplyair temperature, and the volume ofheated plenum air, the leaving airtemperature for the hot water coil canbe determined (see the unit selectionexample that follows for more details).

Coil Entering Air TemperatureThe entering air temperature (EAT) tothe coil also varies based on the coilposition on the unit.

Electric coil EAT equals thetemperature of blended primary airand plenum air because the coil is in ablow-thru configuration. The unit hotwater coil configuration is draw-thru,therefore, EAT equals the plenumair temperature.

Capacity RequirementOnce both coil EAT and LAT aredetermined, the heat transfer (Q) forthe coil must be calculated using theheat transfer equation. For electric heatunits, the Q value must be convertedfrom Btu to kW for heater selection.The required kW should be comparedto availability charts in the performancedata section for the unit selected. Forhot water heat units, reference thecapacity charts in the performance datasection for the required heat transfer Qand airflow to pick the appropriate coil.

Fan Size and Selection

Fan AirflowFan airflow is determined bycalculating the difference betweenthe unit design heating airflow andminimum primary airflow.

Fan External Static PressureFan external static pressure is the totalresistance experienced by the fan,

which may include downstreamductwork and diffusers, heating coils,and sound attenuators. As total airflowvaries so will static pressure, makingcalculation of external static pressuredependent on unit type.

In many applications of parallelterminals, a minimum primary airflowmust be maintained to meetventilation requirements. This primaryairflow contributes to the totalresistance experienced by the fan andshould be accounted for in allcomponents downstream of the fanitself, including electric coils. Hot watercoils are positioned on the fan inlet andare not affected by the additionalprimary airflow. The static pressureresistance experienced by the fan dueto the hot water coil is based on fanairflow only, not the totalheating airflow.

SelectionOnce fan airflow and external staticpressure are determined, reference thefan curves in the performance datasection. Cross plot both airflow andexternal static pressure on eachapplicable graph. If the point isbetween the high and low ranges forthe fan, that fan size will work.

It is common to identify more thanone fan that can meet the designrequirements. Typically, selectionbegins with the smallest fan availableto meet capacity. If this selectiondoes not meet acousticalrequirements, upsizing the fan andoperating it at a slower speed can bedone for quieter operation.

Acoustics

Air Valve Generated NoiseTo determine the noise generated bythe air valve, two pieces of informationare required; design airflow and designair pressure drop. The design airpressure drop is determined by takingthe difference between design inletand static pressure (the valve’s most

over-pressurized condition) and externalstatic pressure at design cooling flow.This represents a worst-case operatingcondition for the valve.

Fan Generated NoiseTo determine fan noise levels, fanairflow, external static pressure andspeed information is required.

Evaluation ElementsFor parallel fan-powered terminal units,the air valve and fan operation must beevaluated separately because theseoperations are not simultaneous.

Access the appropriate acousticstable(s) of the catalog and determinethe sound power and NC prediction forboth the discharge and radiated paths. Itis important to understand thatdischarge air noise is generally not aconcern with fan-powered terminals.Radiated noise from the unit casingtypically dictates the noise level ofthe space.

If the entire unit or any element of it isgenerating noise in excess of the NoiseCriteria requirements, the size of theappropriate portion of the terminalshould be increased. Because theselection procedure is iterative, careshould be taken by the designer toconfirm that the change in selectiondoes not affect other elements of theunit or system design.

Selection Example—

Parallel With Hot Water Heat

Air Valve SelectionRequired Information:

Design cooling airflow: 1000 cfmMaximum wide-openair pressure drop: 0.25 in. wg

Choose a size 10 air valve with wide-open air pressure drop of 0.05 in. wg

Heating Coil SelectionRequired Information:

Zone design heat loss: 20000 BtuUnit heating airflow: 600 cfmWinter room design temp.: 68ºFCoil entering water temp.: 180ºFMinimum primary airflow: 200 cfmPlenum temperature: 70ºFCoil flow rate: 2 gpmPrimary air temperature: 55ºF

Heat Transfer Equation (Btu)Q = 1.085 x Cfm x D Temperature

For the heating zone, the temperaturedifference is the zone supply airtemperature (SAT) minus the winterroom design temperature.

20000 Btu = 1.085 x 600 x (SAT - 68ºF)SAT = 98ºF

Because the hot water coil is on theplenum inlet of a parallel fan-poweredunit, the unit supply air temperature isequal to the mix of the heated plenumair from the fan and the minimumprimary airflow.

600 cfm x 98ºF =200 cfm x 55ºF +(600 cfm - 200 cfm) x Coil LAT

Coil LAT = 121ºF

For the heating coil, the temperaturedifference is the calculated coil LATminus the coil EAT (Plenum AirTemperature).Coil Q = 1.085 x 400 x (121-70) =

22134 Btu = 22.13 Mbh

Coil Performance TableSelection:Size 02 fan, 2-row coil with 2 gpm =30.02 Mbh

2-row coil with 2 gpm = 9.15 ft WPD

Fan SelectionRequired Information:

Design airflow: 400 cfmDownstream static pressureat design airflow: 0.25 in. wg

Fan external static pressure equalsdownstream static pressure (ductworkand diffusers) plus coil static pressure.The coil static pressure that the fanexperiences is at the fan airflow(400 cfm). The downstream staticpressure the fan experiences is at fanairflow plus minimum primary airflow.The sum of fan airflow and minimumprimary airflow (600 cfm) is less thandesign airflow (1000 cfm) and thereforethe 0.25 in. wg downstream staticpressure at design airflow must beadjusted for the lower heating airflow.

Using Fan Law Two:Heating Downstream Static Pressure =(600/1000)2 x 0.25 = .09 in. wg

A size 02 fan has the capability to deliverapproximately 650 cfm at 0.09downstream static pressure.

AcousticsRequired Information:

Design inlet static press.: 1.0 in. wgNC criteria: NC-35

The selection is a VPWF Parallel Fan-powered Terminal Unit, primary air valvesize 10, parallel fan size 02, with a 2-rowhot water coil.

Determine the casing radiated noiselevel because it typically dictates thesound level (NC) of the space. With aparallel unit, two operating conditionsmust be considered, design cooling anddesign heating.

Design Cooling (1000 cfm). The closesttabulated condition (1100 cfm at1.0 in.wg ISP) has the followingtabulated results:

Design Heating (200 cfm valve,400 cfm fan). The closest tabulatedcondition (390 fan cfm at 1.0 in. wg ISP)has the following tabulated results:

The predicted NC level for designcooling is NC-31 and for design heatingis NC-31. If the catalog path attenuationassumptions are acceptable, this unitmeets all of the design requirementsand the selection process is complete.Computer SelectionThe advent of personal computershas served to automate manyprocesses that were previouslyrepetitive and time-consuming. Oneof those tasks is the proper scheduling,sizing, and selection of VAV terminalunits. The Trane Company hasdeveloped 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 required fields,denoted by red shading on the TOPSSscreen, and many other optional fieldsto meet the criteria you have. Requiredvalues include maximum and minimumairflows, control type, and model. Ifselecting models with reheat, you willbe required to enter information tomake that selection also. The user isgiven the option to look at all theinformation for one selection on onescreen or as a schedule with the otherVAV units on the job.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.

SelectionProcedure

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.

Example:

A model VPEF, electric reheat unit size 1005 has 480/3 phase, 12 kW electric reheatwith 2 stages and 277-Volt motor.

For MOP of fan-powered unit:

12 kW - 480/3 heater 12 x 1000 = 14.45 amps480 x 1.73

MCA = (2.6 + 14.45) x 1.25 = 21.31, MOP = (2.25 x 2.6) + 14.45 = 20.3.

Since MOP £MCA, then MOP = 25.

UNIT CONTROLS SEQUENCE OFOPERATIONThe unit controller continuouslymonitors the zone temperature againstits setpoint and varies the primaryairflow as required to meet zonesetpoints. Airflow is limited byminimum and maximum position setpoints. For a parallel unit, the controllerwill intermittently start the fan upon acall for heat. Upon a further call forheat, any hot water or electric heatassociated with the unit is enabled.

1. Primary Airflow—The fan energizeswhen primary airflow drops belowthe fan setpoint airflow. The fanautomatically starts when the zonetemperature drops to the heatingtemperature setpoint.

2. Zone Temperature—The fanenergizes when the zone temperaturedrops to a selectable number ofdegrees above the heatingtemperature setpoint.

DIRECT DIGITAL CONTROLS

DDC Actuator—Trane 3-wire, 24-VAC,floating-point control actuator withlinkage release button. 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 UCM 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,but do so using radio transmittertechnology. Therefore with wireless,wiring from the zone sensor to theUCM is unnecessary.
