Introduction The installed base of ducted HVAC systems is very vast and highly variable. No matter the system, retrofit and upgrading is inevitable. The retrofit terminal units discussed in this catalog are utilized for upgrading existing ducted HVAC systems, most notably in the area of controls. Using Trane’s vast knowledge of air volume control and unit controls, Round Inlet/Round Outlet Retrofit (VRRF) Terminal Units are used to improve energy efficiency and reduce overall operating cost in existing systems. Often VRRF units are used in the following applications:

• Bypass/replace existing mechanical regulator (air valve)

• Upgrade building and/or unit controls (e.g. Pneumatic to BACnet®) with or without replacing the mechanical regulator (air valve)

• Convert Constant Air Volume System to Variable Air Volume System

• Convert pressure dependent Variable Air Volume System to pressure independent Variable Air

Volume System (e.g. Trane VariTrac™)

• Convert Multizone (Dual Duct) Systems to Variable Air Volume System The VRRF terminal unit is also very beneficial for non-retrofit or new applications. This unit allows for great controllability, keeping occupied spaces comfortable in a very compact footprint. For those applications where space is at premium, but controls functionality is not, the VRRF terminal unit is ideal.

Agency Certifications There are numerous regulations and standards in the industry that determine the construction and performance parameters for terminal units. Some of the more important of those standards and regulations are listed below, along with a brief description of what each one addresses.

UL-Listed Products All VariTrane™ units are listed in accordance with UL -1995 as terminal units. This listing includes the terminal with electric heaters. Additionally, all insulation materials pass UL 25/50 smoke and flame safety standards.

AHRI Certified Performance All VariTrane™ units are AHRI certified. AHRI 880 guarantees the pressure drop, flow performance, and acoustical performance provided is reliable and has been tested in accordance with industry accepted standards. AHRI 885 uses AHRI 880 performance and applies accepted industry methods to estimate expected “NC” sound levels within the occupied space.

American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE)

ASHRAE - Standard 41.1 ASHRAE - Standard 41.2 ASHRAE - Standard 41.3 These standards specify methods for temperature measurement (41.1), laboratory airflow measurement (41.2), and pressure measurement (41.3). While none of these standards specifically discusses air terminals, they discuss topics that are aspects of terminal box systems. Therefore, some engineers will include these standards in their specifications as a primer on accepted measurement techniques.

ASHRAE - Standard 62.1 ASHRAE - Standard 111 This standard calls out procedures to be followed for testing and balancing HVAC systems. It includes descriptions of the equipment used, procedures followed, and field changes that must be made when a system is balanced.

Air Conditioning and Refrigeration Institute (AHRI) AHRI Standard 880 This standard sets forth classifications, performance testing requirements, and test results reporting requirements for air terminal units. The standard contains very detailed procedures that are to be followed for the testing and certification program associated with this standard. The operating characteristics tested include discharge and radiated sound power, wide-open pressure drop, and fan motor amp draw.

AHRI Standard 885-2008 This document provides a procedure to estimate sound pressure levels in an occupied space. The standard accounts for the amount of sound pressure in the space due to the air terminal, diffusers and their connecting low pressure ductwork. While sound generated from the central system fan and ductwork may be a significant factor in determining the sound pressure level in the room, this standard does not address those factors. It focuses solely on the terminal and items downstream of it. This standard is related to AHRI-880 by using sound power determined using AHRI-880 methodology as a starting point for the AHRI-885 procedure.

Underwriter’s Laboratory (UL) 1995 Underwriter’s Laboratory is an independent testing agency that examines products and determines if those products meet safety requirements. Equipment manufacturers strive to meet UL guidelines and

VAV-PRC016E-EN 7

obtain listing and classifications for their products because customers recognize UL approval as a measure of a safely designed product. terminals are listed per UL-1995, Heating and Cooling Equipment. The terminals are listed as an entire assembly.

National Fire Protection Association (NFPA)

NFPA 70

This standard is also known as the National Electrical Code (NEC). The Code gives standards for installation of wiring and electrical equipment for most types of commercial and residential buildings. It is often referred to in air terminal specifications when fan-powered boxes, electric heat or electric controls are included.

NFPA 90A

This standard does not speak directly to air terminals but does discuss central system considerations pertaining to a fire and/or smoke condition. The standard discusses safety requirements in design and construction that should be followed to keep the air-handling system from spreading a fire or smoke.

The standard specifies practices that are intended to stop fire and smoke from spreading through a duct system, keep the fire-resistive properties of certain building structures (fire walls, etc.) intact, and minimize fire ignition sources and combustible materials.

Application Considerations Flow Measurement and Control

One of the most important characteristics of a VAV terminal unit is its ability to accurately sense and control airflow. The VariTrane™ terminal unit was developed with exactly that goal in mind. The patented, multiple-point, averaging flow ring measures the velocity of the air at the unit primary air inlet.

The differential pressure signal output of the flow ring provides the terminal unit controller a measurement of the primary airflow through the inlet. The terminal unit controller then opens or closes the inlet damper to maintain the controller airflow setpoint.

Flow Measurement Most of these terminal units contain a differential pressure airflow measurement device, mounted at the primary air inlet, to provide a signal to the terminal unit controller. Numerous names exist for the differential pressure measurement device—flow sensor, flow bar, flow ring. The differential pressure measured at the inlet varies according to the volumetric flow rate of primary air entering the inlet.

The total pressure and the static pressure are measurable quantities. The flow measurement device in a VAV terminal unit is designed to measure velocity pressure. Most flow sensors consist of a hollow piece of tubing with orifices in it. The VariTrane™ air valve contains a flow ring as its flow measuring device.

The flow ring is two round coils of tubing. Evenly spaced orifices in the upstream coil are the high-pressure taps that average the total pressure of air flowing through the air valve. The orifices in the downstream ring are low-pressure taps that average the air pressure in the wake of flow around the tube. By definition, the measurement of static pressure is to occur at a point perpendicular to the airflow.

The low-pressure taps on the VariTrane™ flow ring measure a pressure that is parallel to the direction of flow but in the opposite direction of the flow. This “wake pressure” that the downstream ring measures is lower than the actual duct static pressure. The difference between the “wake pressure” and the static pressure can be accounted for so that the above relationship between flow and differential pressure remain valid. The difference also helps create a larger pressure differential than the velocity pressure.

Since the pressures being measured in VAV terminal unit applications are small, this larger differential allows transducers and controllers to measure and control at lower flow settings than would otherwise be possible.

The average velocity of air traveling through the inlet is expressed in the equation:

FPM = 1096.5

VP

DENS

Where:

• FPM = Velocity of air in feet per minute

• 1096.5 = A constant

• VP = The velocity pressure of the air expressed in inches of water

• DENS = The density of the air expressed in pounds per cubic foot Often, the density is assumed to be a constant for dry air at standard conditions [68°F (20°C)] and sea level pressure of 14.7 psi (101.4 kPa). These conditions yield the following commonly used equation:

FPM = 4005 VP

The amount of air traveling through the inlet is related to the area of the inlet and the velocity of the air:

AIRFLOW (cubic feet per minute, cfm) = AREA (square feet) x AVERAGE VELOCITY (feet per minute)

Accuracy The multiple, evenly spaced orifices in the flow ring of the VariTrane™ terminal unit provide quality measurement accuracy even if ductwork turns or variations are present before the unit inlet. For the most accurate readings, a minimum of 1½ diameters, and preferably 3 diameters, of straight-run

VAV-PRC016E-EN 9

ductwork is recommended prior to the inlet connection. The straight-run ductwork should be of the same diameter as the air valve inlet connection. If these recommendations are followed, and the air density effects mentioned below are addressed, the flow ring will measure primary airflow within ±5% of unit nominal airflow.

Figure 1. Air pressure measurement orientations

Air Density Effects Changes in air density due to the conditions listed below sometimes create situations where the standard flow sensing calibration parameters must be modified. These factors must be accounted for to achieve accuracy with the flow sensing ring. Designers, installers, and air balancers should be aware of these factors and know of the necessary adjustments to correct for them.

Elevation At high elevations the air is less dense. Therefore, when measuring the same differential pressure at elevation versus sea level the actual flow will be greater at elevation than it would be at sea level. To calculate the density at an elevation other than standard conditions (most manufacturers choose sea level as the point for their standard conditions), you must set up a ratio between the density and differential pressure at standard conditions and the density and differential pressure at the new elevation.

Standard Conditions∆P DENS Standard Conditions

∆P New Conditions DENS New Conditions=

Since the data from the manufacturer is published at standard conditions, this equation should be solved for the differential pressure at standard conditions and the other quantities substituted to determine the ratio for the differential pressure measured at the new conditions.

Duct Pressure and Air Temperature Variations While changes in these factors certainly affect the density of air, most operating parameters which systems need keep these effects very small. The impact on accuracy due to these changes is less than one half of one percent except in very extreme conditions. Extreme conditions are defined as those systems with inlet static pressures greater than 5 in. wg (1245 Pa) and primary air temperatures greater than 100°F (37.8°C). Since those types of systems occur so infrequently, we assume the effects of duct pressure and air temperature variations to be negligible.

10 VAV-PRC016E-EN

Linearity With the increased use of DDC controls instead of pneumatic controls, the issue of linearity is not as great as it once was. The important aspect of flow measurement versus valve position is the accuracy of the controller in determining and controlling the flow. Our units are tested for linearity and that position versus airflow curve is downloaded and commissioned in the factory to ensure proper control of the unit.

Retrofit Systems It is very important to understand how the VRRF terminal unit should be applied depending upon the retrofit application. This will ensure that the performance of the system is maintained. This section outlines the most common retrofit applications.

Selection Procedure This section describes the catalog selection of VRRF VAV terminal units with a specific example. A computer selection program, Trane Official Product Selection System (TOPSS™), is also available to aid in selection of VAV terminal units. Selection of VRRF VAV terminal units can involve three elements:

• Air Valve Selection

• Acoustics

• Controls

Trane Select Assist™ Trane Select Assist™ is an online tool used to determine properly sized VariTrane™ VAV terminal unit and resulting performance data for specific input specifications. In addition to selection of VAV terminal unit configuration selections, Trane Select Assist also includes most other Trane products, allowing user to select all required equipment within the one program.

Within the tool, required fields are denoted by red shading, and for VAV terminal units include maximum and minimum airflows, control type, and unit model. (Models with reheat have additional required fields.) The user has the option of viewing information for an individual selection on one screen, or as a schedule with all VAV units required for the specific application.

Trane Select Assist also calculates sound power data for the selected terminal unit. Input is either maximum individual sound level for each octave band, or maximum NC value. Trane Select Assist will calculate acoustical data subject to default or user-supplied sound attenuation data.

Schedule View: The program has many time saving features such as:

• Copy/paste from spreadsheets like Microsoft® Excel

• Easily arrange fields to match your schedule

• Time-saving templates to store default settings The use can also export the schedule view to Excel for modification or inclusion in engineering drawings as a schedule. Details regarding the program, its operation, and instructions on obtaining a copy are available from your local Trane sales office.

Air Valve Selection The wide-open static pressure and airflows are found in the performance data section of the catalog. To select an air valve, locate the required design cooling airflow for your terminal unit type and find the smallest air valve size that has a pressure drop equal to or lower than the maximum wide-open static pressure requirement.

Example: Cooling Only VCCF Terminal Unit

• Design cooling airflow: 1700 cfm

• Maximum wide open Air pressure drop: 0.25 in. wg

• Minimum 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 cfm desired with the minimum and maximum cfm allowed in the table in the general data section. The maximum setting of 1700 cfm is within the acceptable range. The desired minimum setting of 850 cfm is acceptable for the cooling only box desired. Note that if an electric reheat box was selected, the minimum cfm would be dependent upon the kW of the electric heater. (See Electric Heat Unit Selection.)

Acoustics The acoustical data found in the VAV catalog is used to determine sound the terminal unit will generate.

Locate the table for the VAV terminal unit of interest. Sound power data and an equivalent NC level for an AHRI 885-2008 transfer function is listed.

VAV-PRC016E-EN 15

Example: VRRF, Size 12 (See air valve selection)

• Cooling Airflow: 1700 cfm

• Maximum inlet static pressure: 1.5 in. wg Interpolation gives sound power data of:

Octave Band 2 3 4 5 6 7 NC

Discharge Sound Power 77 70 67 63 64 60 30

Radiated Sound Power 46 53 54 53 52 50 29

The NC level above is determined by using either the catalog’s AHRI 885-2008 (mineral fiber for radiated sound) transfer function for the conditions shown in the acoustics table. A different transfer function could be applied as conditions dictate.

The maximum NC level is NC-30. If the maximum NC level was exceeded, it would have been necessary to reselect the next larger unit size.

Controls Proper control type selection is crucial to VRRF application. In most instances, the control type will need to match the exisiting building control system type. For example, VariTrac™ communicating via Comm3/ Comm4 will require the UCM control type. See more detail in the Controls portion of the catalog.

Controls Tracer Building Automation System

Tracer® Building Automation Systems ensure comfort within your building.

Building controls have a bigger job description than they did a few years ago. It’s no longer enough to control heating and cooling systems and equipment. Sophisticated buildings require smarter technology that will carry into the future. Tracer controls provide the technology platform – mobile, easy-to-use, cloud-based, scalable and open - for the next generation of data-driven, technology-enabled services that are creating high performance buildings.

With a Trane Tracer® Building Automation System, you’ll:

• Reduce operating costs through energy management strategies.

• Consistently provide occupant comfort.

• Enjoy reliable operation with standard, pre-engineered, and pretested applications.

• Easily troubleshoot and monitor either on site or from a remote location.

• Reduce installation time and simplify troubleshooting.

Whether factory-mounted or field-installed, Trane offers a wide range of controllers to suit virtually any application. These units are compatible with a variety of building types and can be used for new construction or renovation. Through extensive usability testing internally and with building operators, we’ve designed our controls for real world ease of use.

Tracer BACnet Controllers Trane offers a full line of programmable BACnet® controllers designed for simple integration into any system which can communicate via the BACnet® protocol. These controllers are factory-downloaded, commissioned, and shipped ready to be installed.

Tracer VV550 LonTalk® Controllers Trane offers a full line of LonTalk® controllers designed for simple integration into ANY system which can communicate via the LonTalk® Space Comfort Control (SCC) protocol. These controllers are also completely factory-commissioned.

Trane VAV DDC UCM Controller DDC (communicating electronic)—DDC controllers provide system-level data used to optimize overall system performance. Variables such as occupied/unoccupied, minimum and maximum airflows and temperature, valve position, ventilation fraction, and so on are available on a simple Trane Comm3/4 protocol twisted-shielded wire pair.

Note: One of many Trane DDC Control options which are factory-installed, wired, calibrated, and fully tested before shipment.

Trane DDC controllers provide Trane-designed solid-state electronics intended specifically for temperature and ventilation control in space comfort applications. DDC control capabilities include:

• Pressure-independent (PI) operation—Provides airflow required by the zone temperature sensor to maintain occupant comfort. The controller automatically adjusts valve position to maintain required airflow. Minimum and maximum airflow is factory-set and field-adjustable.

• Factory-set airflow and temperature setpoints.

Air-Fi® Wireless System For more detailed information on Air-Fi® Wireless systems and devices, see:

VAV-PRC016E-EN 27

Air-Fi® Wireless Communications Interface (WCI)

A factory-installed Air-Fi® Wireless Communications Interface (WCI) provides wireless communication between the Tracer® SC, Tracer® UC210/UC400, Symbio™ 210/Symbio™ 210e/ Symbio™ 500 VAV unit controllers and optionally, Air-Fi® Wireless Communication sensors.

The Air-Fi® WCI’s wireless mesh network is the perfect alternative to a wired communication link. Eliminating the low-voltage wire between the zone sensor and the terminal unit controller, and between the unit controllers and the system controller will:

• Reduced installation time and associated risks.

• Completion of projects with fewer disruptions.

• Easier and more cost-effective re-configurations, expansions, and upgrades.

Note:WCI is not compatible with the Trane VAV UCM or

Tracer® VV550 LonTalk® controller.

Air-Fi® Wireless Communication Sensor (WCS)

The Wireless Communications Sensor (WCS) communicates wirelessly to a Tracer® BACnet® unit controller that has an Air- Fi® WCI installed. AWCS is an alternative to a wired sensor when access and routing of communication cable are issues. It also allows flexible mounting and relocation. Also available are a non-display version of the WCS with a temperature setpoint knob, an occupancy / CO2 sensor / zone temperature version of the WCS, and a relative humidity (RH) sensor add-on daughter board accessory.

Factory-installed vs. Factory-commissioned The terms factory-installed and factory-commissioned are often used interchangeably. Trane takes great pride in being the industry leader in factory-commissioned DDC controllers. The following table differentiates these concepts.

Factory-commissioned controllers provide the highest quality and most reliable units for your system.

Additional testing verifies proper unit operation including occupied/unoccupied airflow and temperature setpoints, communication link functionality, and output device functionality. The benefits of factory-commissioning are standard on VariTrane™ terminal units with Trane DDC controls. This means that factory-commissioned quality on VariTrane™ units is now available on ANY manufacturer’s control system that can communicate using the LonMark® Space Comfort Control (SCC) protocol or the BACnet® protocol. (See Controls section for complete listing of variables which are communicated.)
