• TemperatureIndex=[Tsi-To]/[Ti-To]x100=55.Thisequationcanbe used to calculatethesurfacetemperatureforanycombinationofinsideand outside air temperatures. The resulting surface temperature can be compared to the dew point temperature of indoor air to determine if condensation will occur.

(Condensation is a function of the damper surface temperature, the inside environment temperature and the inside humidity levels. The inside surface temperature is affected by the amount of heat loss through the blade (see temperature index number), and outside cold air infiltration.)

(Condensation is a function of the damper surface temperature, the inside environment temperature and the inside humidity levels. The inside surface temperature is affected by the amount of heat loss through the blade (see temperature index number), and outside cold air infiltration.)

• An effective thermal break keeps the inside surfaces warmer. This permits a higher indoorhumiditywithoutcausingcondensation.Whencondensationdoesoccur,incasesofveryhighhumidity,itissignificantlyreducedandthisinhibitsicingtocolderoutdoortemperatures.

S E L E C T I O N T A B L E AREA FACTOR

Thetable(above)andthechart(below)areusedtofindthepressuredropthroughallTAMCOThermallyInsulatedDampers.1) In the above table, select the area factor value recorded, where the duct width column and duct height line meet.

2) In the chart below, enter the area factor obtained from above and the cfm for the application and read the pressure drop off where the “Area Factor” line and the “Volume Flow Rate” column meet. (Example: duct size 20”w x 32”h = .32 area factor, (above table). Then, if cfm is 2000, pressure drop = .012” w.g. (chart below).

S E L E C T I O N C H A R T PRESSURE DROP

Note: 1. Ratings are based on AMCA Standard 500, using Test Setup Apparatus Figure 5.3 (damper installed with duct upstream & downstream).2. Above Area Factor values are based on flanged-to-duct type installations. Pressure drop will be greater for installed in-duct type dampers. Call TAMCO Customer Service at

1-800-561-3449 for pressure drop calculations for installed in-duct type dampers.3. Dampers sized for duct openings exceeding 37½” (953 mm) in height are equipped with a stiffener bar at mid-height, which is reflected in the above chart.

Note: 1. Ratings are based on AMCA Standard 500, using Test Setup Apparatus Figure 5.3 (damper installed with duct upstream & downstream).2. Above Area Factor values are based on flanged-to-duct type installations. Pressure drop will be greater for installed in-duct type dampers. Call TAMCO Customer Service at

1-800-561-3449 for pressure drop calculations for installed in-duct type dampers.3. Dampers sized for duct openings exceeding 37½” (953 mm) in height are equipped with a stiffener bar at mid-height, which is reflected in the above chart.

BEFORE INSTALLATION

(A) To correctly verify sealing action, loosen hex nuts of U-bolt located on drive blade. Extend steel drive rod to maximum of 9” past frame. Re-tighten hex nuts on U-bolt.

(B) Using drive rod, slowly apply closing torque, while ensuring that damper frame does not twist due to torque being applied. (Larger dampers may require additional person to hold damper frame square and true.)

(C) If possible, use daylight or inside light source as a backdrop to verification procedure. No light should be visible through damper.

CAUTION SHOULD BE EXERCISED TO ENSURE FINGERS ARE NOT IN WAY OF MOVING LINKAGE PARTS OR BLADES.

Intermediate structural support required.

DESIGN OF STRUCTURAL SUPPORT FOR TAMCO DAMPERS

��

��

Example:Design the structural support required to carry TAMCO dampers at the 17th story of a building in Ottawa, Ontario, Canada. (Assuming that the maximum internal pressure, as a resultofthemechanicalsystems,is2inchesofwater,10.4psfor500Pa.)

Assumptions:The subject building is 17 floors high and has plan dimension of 120' by 120' (36.6m by 36.6m). The dampers will be mounted on vertical framing members spanning from the 17th floor to the roof slab level.

Analysis: Net wind pressure exterior pressure interior pressure in the mechanical plenum on damper or suction (as specified by the mechanical engineer)

p = qCeCgCp external + 10.4 psf 1997 OCB 4.1.8

Where:p = the specific external pressure acting statically and in a direction normal to the surface, either as a pressure directed towards the surface or as a suction directed away from the surface.

q = the reference velocity pressure based on a 1 in 30 probability of being exceeded in any one year for design of structural members for strength. q1/30 = 7.72 psf(0.37kPainOttawa,Ontario).

Ce = exposure factor based on the height of the building (1.4 for a 170 ft. high building).

Cg = gust factor (2.5 for cladding elements and small structural components). Cp = external pressure coefficient (1.0 for high local suction).

p = qCeCgCp external + 10.4 psf

p = 7.72 psf (1.4) (2.5) (1.0) + 10.4 psf p = 37.4 psf

Total net factored pressure: pf = 1.5 (live wind load) pf=1.5•(37.4) pf = 56.1 psf (2.7 kPa)

Factored distributed load over vertical support framing member: wf = 56.1 psf (5') wf = 281 lb./ft.

Factored maximum moment: Mf = wf l²/8 Mf=281•(10)²/8 Mf = 3513 lb./ft. (4.8kN•m)

= + Resisting moment: Mr has to be equal to or greater than Mf for an unsupported length of 10' (3.05m)

Acceptable vertical support member:

C4 x 6.0 - 4" structural steel channel (metric designation C100 x 9) Mr = 3980 lb.ft. foranunsupportedlength(Lu)=13'. (Mr = 5.4 kNm atLu=4m)

Check deflection criteria:

Maximum allowabledeflectionisL/320=10'/320=0.375"(9.5mm)Maximum deflection at mid-height of the channel:

∆ = 5 w l4 384 E I

For deflection, the reference velocity pressure, q, is based on a 1 in 10 probability of being exceeded in any one year. q1/10 = 6.27 psf (0.30kPain Ottawa, Ontario). p = qCeCgCp external + 10.4 psf p = 6.27 psf (1.4) (2.5) (1.0) + 10.4 psf p = 32.3 psf w = 32.3 psf (5') w = 162 lb./ft.

∆ = 5 (162 lb./ft.) (10')4 384 (29,000 ksi) (4.25 in4)

∆ = 5 (13.5 lb./ft.) (120")4 = 0.30 (7.6mm)

384(29•106 psi) (4.25 in4)

Therefore, an acceptable vertical support member for this example is a C4 x 6.0. (metric designation C100 x 9)

LINEARITY INFORMATION

For two-position or shut-off applications, where dampers are always either fully open or fully closed, flow control characteristics are largely irrelevant. Shut-off dampers should be selected and sized to minimize pressure drop in the full open position, and to minimize air leakage and maximize thermal performance in the closed position. TAMCO Dampers are ideal in these applications.

For applications where dampers are used to control flow over a range of air flows, it is necessary to size the dampers based on the pressure drop of the damper in differentpositions,theresistanceoftheduct’ssystemthatthe damper affects, and the characteristics of the control signal. The interactions between a flow control damper, the system in which it is installed, and the controls can be complex. It is critical for proper control and efficient system operation, that known and controllable factors be optimized. To this end, most control system manufacturers have developed sizing guidelines. We recommend that the detailed sizing procedures provided by control manufacturers and ASHRAE, be used for sizing dampers, especially in complex or critical applications. The following sections provide information on the characteristics of TAMCO dampers to be used in these design methods and also provides some further general sizing guidelines that may be appropriate in simple systems.

FLOW CONTROL DAMPERS

The pressure drop and flow of TAMCO Series 1000, 1500, & 9000 dampers were tested to AMCA Standard 500-89 at blade angles of 15, 30, 45, 60, 75 and 90 degrees.

The results confirmed that the performance characteristics (linearity curves) of TAMCO Series 1000, 1500, and 9000 dampers are comparable to the assumptions used by major control system manufacturers and the ASHRAE handbooks.

Figures 1 and 2 show the tested “characteristic curves” for parallel and opposed blade TAMCO dampers, and com-pare them to other published data.

GENERAL SIZING GUIDELINESEven for general sizing guidelines, one must understand the term "Damper Authority", which is defined as the following ratio:

pressure drop across a control damper in the full open position

total pressure drop of the portion of the system that the damper controls.

(Note that some manufacturers refer to characteristic ratios instead of damper authority. This is the ratio of the “series” resistance to damper resistance, where series resistance is the total system resistance less damper resistance.)

The characteristic curves shown in Figures 1 and 2 correspond to the 100% authority curve, where the entire pressure drop of the system occurs across the damper. As can be seen, this curve is not linear. As Damper Authority decreases (system pressure drop excluding the damper goes up), the shape of the flow versus blade angle curve changes. A family of curves can be plotted as in Figures 3 and 4, showing damper performance at various values of Damper Authority.In most, but not all, flow control applications, a linear performance is desired. Proper sizing of the damper will result in economical damper selections, with performance close to linear. System characteristics, as well as damper characteristics, must be addressed.Two approaches can be taken to size control dampers correctly. The first method, often used by system designers, is iterative. The designer selects an arbitrary damper size, often the full dimension of the duct, determines pressure drop across the damper at full flow from manufacturer selection charts,anddoesa“checkcalculation”fordamperauthority.Iftheresultindicates that the damper authority is insufficient for the application, smaller dampers are selected until required authority is achieved.The second method consists of calculating the desired pressure drop across the damper at full flow, using the appropriate authority values and calculated duct system pressure losses. The procedure is:•Calculatetheductsystempressurelossatfullflow,excludingthecontroldamperloss,whichisstillunknown.•Selectthedamperauthorityrequiredtoprovidethedesiredcontrolcharacteristics.•Calculate the control damper pressure loss at full flow: PD = (DA / (100 - DA) x PS where PD = damper pressure drop at full flow / DA = damper authority, selected by designer / PS = duct system pressure loss, calculated using standard methods.

•Selectdampersizesfromthecalculatedrequiredpressuredrop,PD,andmanufacturer’sselectioncharts.

When air flow must be controlled in direct proportion to a control signal, a linear performance characteristic is desirable. A typical application is throttling air flow to maintain a space temperature, such as with a VAV box. Referring to the authority curves, it is apparent that a parallel blade damper should be selected to have an authority of approximately 20% to 25%, and for an opposed blade damper, approximately 8% to 10%. An example using TAMCO selection charts is provided below.

Example of damper sizing for linear performanceAssumptions: Sizing Series 1000/1500/9000 dampers for linear performance in a system with a duct system (series) pressure drop, excluding damper, of 0.2 inches w.g. at full flow of 5000 cfm.

OTHER CASES

MIXED-AIR CONTROL

A typical application is the economizer section in an air handling system, where two air streams are mixed to maintain a fixed temperature set point. To achieve stable and predictable static pressures and improved energy efficiency and comfort, the dampers should be sized so that the total flow rate of the system remains constant. This is generally best achieved by selecting dampers that are sized to provide linear performance in the range of interest. For dampers in ducted systems, this usually requires that the outside air, return air, and exhaust dampers all be selected with similar authority, in the order of 8% to 10% for opposed blade dampers, or 20% to 25% for parallel blade dampers. However, in many cases, the outside air damper is installed behind the intake louver and is the same size as the louver in an effort to reduce entry of snow and rain. This results in grossly oversized dampers. In this case, size the outside and exhaust dampers with the same authority. Opinions differ on sizing the return damper in this situation. A general guideline would be to select a parallel blade damper with a pressure drop similar to the pressure difference between the inlet and exhaust ducts at the return duct takeoff. The outside and exhaust dampers should be of the opposed blade type.

FACE & BYPASS CONTROL

For face and bypass applications, the pressure drop through both sections should be the same. Size the bypass damper so that the pressure drop is the total of coil plus coil damper pressure drops.

PRESSURE CONTROL

This application is no longer common since the advent of cost-effective variable-speed drives and fan inlet vanes. Both are more energy efficient and should be considered over damper control for these applications.

RICHARD J. DALEY CENTERMr. Dan Romero, Chief Engineer at the Richard J. Daley Center, Chicago, headed the project to retrofit one of the key systems in this building. The primary requirement was to find a low-leakage, maintenance-free damper product that could withstand 9 inches of static pressure.

A meeting between Stern Mechanical, Mr. Romero and Mr. Jim Karambelas was instrumental in developing a plan for TAMCO to supply more than 2,700 square feet of dampers for this job. The damper selected was the Series 1500 (AMCA certified at 1.7 cfm/sq.ft. at 1 inch of static pressure). The application also called for the use of specially designed, TAMCO horizontal and vertical jack-shafts. Pneumatic actuators were used in a tandem position, as shown in the picture on the right.

MB Real Estate was so pleased with TAMCO’sproductandservicethattheyare proceeding with replacing existing dampers with TAMCO dampers for the rest of this project.

The TAMCO Series 1500 was specified for this entire project. The contract was secured as a result of the solid representationofTAMCO’sinnovativedamperssolutionsby E.I.P. to E.S.D. Engineering. Johnson Controls purchased more than 3,100 square feet of TAMCO’s dampers, toinstall at One North Wacker Drive, Chicago.

F. E. Moran was the mechanical contractor on this project. Mr. Ed Walsh, Chief Engineer at the John Buck Company (general contractor), was very impressed with the quality of the product and service obtained from both E.I.P. and TAMCO.

TAMCO SUCCESS STORIES


Indiana University & Purdue University Indianapolis (IUPUI) chose TAMCO dampers to replace all of the existing dampers in the Business Spea Building, in Cavanaugh Hall and in the University Library. In total, over 600 square feet of TAMCO Series 9000 Thermally Insulated Dampers, Series 9000 SC Severe Cold Option Dampers and Series 1500 Ultra-low Leakage Dampers were installed. TAMCO dampers were used to replace old dampers that had failed due to freeze-up and wear over the years.

This project was secured by Keller-Rivest, the exclusive distributor for TAMCO products in Indiana. Mr. Frank Haag, of Keller-Rivest, met with the engineering staff at IUPUI. He offered the university a free damper which was used as a replacement on an air handling unit. The engineers were extremely impressed with the performance of the TAMCO damper. Following this initial testing, the engineers presented the TAMCO damper to the University architects, who approved the dampers and have listed TAMCO as standard in their specifications ever since.

Mr. David Pfeifer (Energy Systems Project Manager - Campus Facility Services) stated that the TAMCO insulated dampers were installed in all outside air applications, because they are the optimal solution in cold winter conditions. “They have good insulation value and good weather seals...they protect coils against freeze-up.” IUPUI selected Series 1500 dampers for all their return and exhaust air applications.

TAMCO GOES TO SCHOOLTheir ultra-low leakage rate makes them ideally suited to these applications, while providing a means of cost control on a damper replacement project of this size.

Mr. Pfeifer indicates that one of the key selling features of TAMCO dampers is “...they came straight from the factory more square than those of other damper manufacturers.”

Mr. Pfeifer also lists the robust jack shafts and weather-tight seals as other selling points. “We have used all of the accessories and have been impressed with their performance.”

IUPUI has found that the installation of TAMCO dampers is easier, because of the one-inch wide flanges which provide a flat surface to insert screws. They also preferred TAMCO dampers because “Z” plates are provided with all multi-section dampers and holes are pre-drilled for jack shafts.

The engineers and project managers at IUPUI have been very impressed with the reliability of TAMCO dampers. Mr. Pfeifer says, “The TAMCO dampers have been installed at the university for over two and half years and have not needed any maintenance, and they still perform like new! The university has replaced three buildings completely with TAMCO dampers and three new buildings will have TAMCO dampers in all the air handlers when we finish.”

“...TAMCO dampers have been installed at the university for over two and half years and have not needed any maintenance, and they still perform like new!”
