Product Information

General InformationThe Price SPVQ (pneumatic controls), and SDVQ (digital controls) single duct VAV assemblies integrate both VAV and Silencer Technology into one complete package. These units are designed to control airfl ow rate of conditioned air into an occupied space while achieving the lowest noise levels in the industry. The Q series terminal is ideal for noise-sensitive applications such as classrooms, libraries, performance halls and studios.

The acoustical discharge silencer is a direct coupled unit that mates perfectly with the VAV terminal unit. The VAV casing is lined with 1 inch insulation for optimum noise reduction and is designed to ensure an even velocity profi le into the silencer section. The casing design and optimized silencer geometry reduce self-generated noise, minimize pressure drop and maximize acoustic attenuation. Extensive lab testing was used to determine the best combination of terminal and silencer confi guration resulting in an assembly which achieves room noise levels of less than NC 35 without the addition of downstream acoustic insulation.

The complete VAV terminal/silencer assembly has been tested and certifi ed in accordance with AHRI Standard 880. The discharge and radiated sound data presented in this catalog is based on complete assemblies tested in the Price lab. No calculations or system effect assumptions are required to determine silencer performance.

In the past, selection of VAV terminals with silencers has been a complex and risky proposition. The designer had to select the silencer from a variety of available models, free areas and sizes, evaluating silencer attenuation, self-generated noise and pressure drop without really knowing the performance effect of a close coupled silencer/terminal combination. Price eliminates the guess work by providing an optimized, fully tested and certifi ed assembly.

These fully tested units with optimized geometry have similar pressure drops to that of standard SDV units. This allows the engineer to eliminate allowances for extra silencer pressure drop in the HVAC system.

Price SDVQ series terminals are designed to take advantage of a silencer’s acoustical and aerodynamic properties producing an extremely quiet unit while maintaining all the Price SDV standard features. (Refer to Price SDV catalog page F10 for all standard features and benefi ts associated to the SDV terminal unit.)

Price offers an extensive system of liners available with the SPVQ/SDVQ product line. These liners offer various degrees of fi berglass protection suitable for hospital, pharmaceutical, laboratory, and other types of clean room applications.

While specifying liners for SPVQ/SDVQ construction of both the terminal and silencer sections need to be selected:

• The terminal unit itself can be built with our typical selection of liners available for Single Ducts and other Price terminals – SM, PM, AFPM, WFPM, CRAF, CRWF, FF, and FB as listed on page F61-F62. They all meet NFPA90A and offer various degrees of fi berglass protection.

• The VAV silencer section of SDVQ terminals can be manufactured with two types of “hospital grade” liners – PL (polymer fi lm) and FC (fi berglass cloth)

FCFiberglass Cloth Liner SystemStandard construction features of the Price PL features tightly woven fi berglass cloth wrapped around fi berglass media and covered with perforated metal liner which is facing the air inside of the silencer. The cloth prevents shedding of fi berglass media but as a porous material it does not com-promise the sound absorption. This liner offers optimum sound performance, basi-cally no correction factors have to be taken into an account and performance equal to fi berglass lined silencers is achievable. Note that fi berglass cloth is rated below 25/50 for fl ame and smoke development per ASTM E 84 and as such meets NFPA90A.FC Liner System complies with the following industry standards and tests:• UL 181 (Air Erosion)• UL 181 (Mold Growth & Humidity)• UL 723 (25/50) (Flame & Smoke)• ASTM E 84 (25/50) (Flame & Smoke)• ASTM C 665 (Fungi Resistance)• ASTM C 1071 (Physical Properties)

SMSolid Metal Liner SystemThis system integrates a fiberglass insulating material with a solid sheet metal liner constructed from zinc-coated steel. The solid metal liner system complies with the following industry standards and tests:•UL181(AirErosion)•UL181(MoldGrowth&Humidity)•UL723(25/50)(Flame&Smoke)•ASTME84(25/50)(Flame&Smoke)•ASTMC665(FungiResistance)•ASTMC1071(PhysicalProperties)Solid metal liners offer the ultimate protection against exposure of fiberglass particles to the airstream. The fiberglass insulation is completely enclosed in metal all but eliminating the possibility of punctures exposing the fiberglass particles. This system is also resistant to moisture. The encased insulation pro vides thermal resistance, however, acoustic absorption of discharge noise is significantly reduced.

The following thicknesses are available•SM - 3/4"(19)thick•SM1-1"(25)thick

PMPerforated Metal Liner SystemThis system integrates a fiberglass insulating material with a perforated metal liner constructed from coated steel. The edges are sealed with metal caps. The perforated metal liner system complies with the following industry standards and tests:•UL181(AirErosion)•UL181(MoldGrowth&Humidity)•UL723(25/50)(Flame&Smoke)•ASTME84(25/50)(Flame&Smoke)•ASTMC665(FungiResistance)•ASTMC1071(PhysicalProperties)The metal perforated liner system provides effective protection against damage of the insulation while maintain-ing some acoustic value. Small fiberglass particles could conceivably still escape through the perforations and moisture can also be exposed to the insulation.

The following thicknesses are available•PM - 3/4"(19)thick•PM1-1"(25)thick

AFPM Aluminum Foil with Perforated Metal Liner SystemThis system integrates foil-faced fiber-glass insulating material with aluminum foil over a perforated metal liner. The edges are sealed with metal end caps to prevent particles from entering the airstream. The aluminum foil is wrapped around the perforated metal liner, trap-ping it between the insulation and the metal liner.

FBThe double liner system (aluminum foil/perforated metal) complies with the following industry standards and tests:•UL181(AirErosion)•UL181(MoldGrowth&Humidity)•UL723(25/50)(Flame&Smoke)•ASTME84(25/50)(Flame&Smoke)•ASTMC665(FungiResistance)•ASTMC1071(PhysicalProperties)The aluminum foil with perforated metal liner system provides effective protection against damage of the liner and/or insulation while maintaining some acoustic value. The aluminum foil prevents fiberglass particles from escaping through the perforations as well as resistance to moisture penetration.

WFPMWoven Fabric with Perforated Metal Liner SystemThis system integrates a fiberglass insulating material with a liner of woven fabric to prevent particles from entering the airstream. The woven fabric is wrapped around the perforated metal liner, trapping it between the insulation and metal liner. The edges are sealed with metal caps. The double liner system (woven fabric/perforated metal) complies with the following industry standards and tests:•UL181(AirErosion)•UL181(MoldGrowth&Humidity)•UL723(25/50)(Flame&Smoke)•ASTME84(25/50)(Flame&Smoke)•ASTMC665(FungiResistance)•ASTMC1071(PhysicalProperties)The woven fabric with perforated metal liner system provides effective protection against damage of the liner and/or insula-tion, while maintaining some acoustic

value. The woven fabric prevents fiber-glass particles from escaping through the perforations. Since the fabric is porous, the system is not totally impervious to moisture.

FB Foil Board Liner SystemThis system integrates 4lb density rigidfiberglass insulating material with an aluminum foil liner. Exposed edges are coated with NFPA-90A approved sealant. The fiberglass insulation and aluminum foil liner complies with the following industry standards and tests:

FF Fiber Free Foam Insulation SystemThis system integrates an engineered foam which provides excellent insulating characteristics. The foam edges are self sealing due to the material’s composition.

The engineered polymer foam complies with the following industry standards and tests:

•UL181(AirErosion)•UL181(MoldGrowth&Humidity)•UL723(25/50)(Flame&Smoke)•ASTME84(25/50)(Flame&Smoke)•ASTMC665(FungiResistance)•CAN/ULC-102.2-M88

(Flame and Smoke)

Fiber free foam insulation totally eliminates the risk of fiberglass particles entering the airstream while maintaining thermal resistance and acoustic absorption. An important advantage over other liner systems is that even scrapes or punctures will not expose fibers to the airstream. The foam also will not absorb water, reducing the likelihood of mold or bacterial growth. Acoustic absorption of the foam insulation is equivalent to aluminum foil faced insulation.

The following thicknesses are available•FF50 - 1/2"thickRvalue=2•FF- 3/4"thickRvalue=3•FF1-1"thickRvalue=4

CRAF Cleanroom Aluminum Foil SystemThissystem integratesa rigid4 lb.den-sity fiberglass insulating material with an aluminum foil facing. All edges are sealed with metal endcaps and corner angles to prevent particles from entering the air-stream.

The liner’s integrity is maintained where the damper shaft penetrates the insu-lation by a flanged nylon bushing. To reduce risk of liner damage during instal-lation, sealed-in-place s-cleats are pro-vided at the discharge collar.

The inlet duct is sealed to the internal insulation with mold-resistant caulking whichmeetsASTMD-4300.

The fiberglass insulation and aluminum foil liner complies with the following in-dustry standards and tests:

•UL181(AirErosion)•UL181(MoldGrowth&Humidity)•UL723(25/50)(Flame&Smoke)•ASTME84(25/50)(Flame&Smoke)•ASTMC665(FungiResistance)•ASTMC1071(PhysicalProperties)

Acoustic absorption of aluminum foil lined insulation is reduced compared to standard unlined units. The aluminum foil liner is non-porous, thereby protect-ing the insulation from moisture. The smooth surface of the liner reduces the risk of micro-organisms being trapped in the material and also facilitates cleaning. Damage to the liner can expose fiberglass particles to the airstream.

The following thicknesses are available•CRAF - 5/8"thickRvalue=2.6•CRAF1-1"thickRvalue=4.2

CRWF Cleanroom Woven Fabric SystemThis system integrates fiberglass insu-lating material with a woven fabric liner. All edges are sealed with a metal end cap and corner angle to prevent particles from entering the airstream.

The liner’s integrity is maintained where the damper shaft penetrates the insu-lation by a flanged nylon bushing. To reduce risk of liner damage during instal-lation, sealed-in-place s-cleats are pro-vided at the discharge collar.

The inlet duct is sealed to the internal insulation with mold resistant caulking whichmeetsASTMD-4300.

The fiberglass insulation and fabric liner complies with the following industry standards and tests:

•UL181(AirErosion)•UL181(MoldGrowth&Humidity)•UL723(25/50)(Flame&Smoke)•ASTME84(25/50)(Flame&Smoke)•ASTMC665(FungiResistance)•ASTMC1071(PhysicalProperties)

The woven fabric liner provides acoustic absorption equivalent to aluminum foil faced insulation with slightly improved attenuation at high frequencies. The fab-ric is more porous than aluminum foil, therefore moisture can be absorbed into the insulation. If the liner is damaged, fiberglass particles can be exposed to the airstream. The woven fabric liner has been specified in certain areas for many years and has a proven track record in health care applications.

The PRICE SP300 Velocity Pressure Sensor represents the next generation of airflow measurement devices, significantly advancing VAV sensing technology. Developed by PRICE Engineering, the SP300 addresses many of the sensor issues that are critical to today’s modern HVAC designs:

Improved AccuracyTraditional Velocity Pressure Sensors function best under ideal inlet conditions. Most devices require at least four inlet diameters of straight duct before the air terminal connection – a condition that may not exist for a job site installation. Space constraints, other mechanical system components, and structural elements, are factors that can influence air terminal inlet conditions.

When poor inlet conditions exist, the profile of the air moving through the terminal and across the sensor becomes distor ted, resulting in non-uniform velocity distribution, and inaccurate air f low measurements. Under these conditions, the flow sensor must provide a true averaged velocity pressure signal for proper control.

The PRICE SP300 overcomes the effects of variable inlet velocities by averaging and amplifying pressure signals.

Optimal Center AveragingTo compensate for variations in pressure within the inlet, the PRICE SP300 averages the high and low Velocity Pressures that are found on opposing sides of the duct. These measurements are collected and averaged in a chamber located at the center of the sensor. The signal is then sent to the airflow controller.

Multiple ports for sensing both Total (TP) and Static (SP) Pressures are designed and located to maximize accuracy. Extensive research and lab testing was conducted under various air f low conditions to determine the proper location of the multiple sensing ports. Twelve total pressure ports are located on the upstream side of the sensor legs. Four static pressure ports are located on the downstream side of the averaging chamber. The multiple sensing ports not only provide a good indication of velocity across the duct but

prevent loss of signal due to blockage by dust or dirt.

While equal area velocity pressure traverses are recommended for uniform flow conditions, substantial errors occur with non-uniform flow created by a 90° elbow, for example. The total and static pressure port locations for each size of the Price SP300 sensor have been determined by extensive lab tests and experimentation. The end result is flow measurement accuracy within 5% with a 90° sheet metal elbow connected directly to the terminal unit inlet.

Elbows, transitions and duct takeoffs, within three duct diameters of the terminal unit inlet should be avoided due to sound and pressure drop considerations. However, when job conditions do necessitate less than ideal inlet conditions, the Price SP300 will maintain flow accuracy.

Optimal Signal AmplificationAmplifying the Velocity Pressure signal that is sent to the controller will enhance accuracy, especially under low airflow conditions. I t is impor tant to note, however, that too much amplification, and the methods used to achieve it, can be detrimental to sensor performance. In fact, sensors that provide excess amplification may require the use of controllers with higher velocity pressure ranges, thereby reducing low end resolution. The amplification of the SP300 sensor has been designed to provide velocity pressure signals which fall within the standard 0-1.0 inch range of most flow controllers and transducers. By matching the sensor output to the controller input range, optimum flow accuracy is obtained.

Generally, VAV controllers require a minimum differential pressure signal of .03" w.g. to maintain reasonable control accuracy. The PRICE SP300 will provide a .03" w.g. signal for flows as low as 400 FPM at the inlet. Most sensors require more airflow and a higher differential pressure, and many will not function properly below 700 FPM.

Precise control at minimum settings is critical in maintaining the air change rates called for by ASHRAE and good IAQ design practices. Accurate control at minimum flow can also reduce the requirement for reheat and increase room comfort conditions by prevention of overcooling.

Aerodynamic ProfileThe PRICE SP300 sensor utilizes aerody-namic principles to optimize the velocity pressure signal amplification. Strategic location of the total and static pressure ports provides the necessary amplification without the need to increase the sensor profile. An increased sensor profile can result in added noise levels and higher minimum static pressure requirements, both of which are undesirable. The Price SP300 sensor has been designed with minimum cross-section and an aerodynamic profile which has negligible pressure drop or noise contribution.

Structural IntegrityThe PRICE SP300 has superior tensile strength compared to other flow sensors on the market. PRICE does not recommend lifting terminals by the air flow sensor, however, it is often a common practice in the field. With this in mind the PRICE SP300 has been designed with molded reinforcement to prevent accidental handling damage. To ensure reliability, the SP300 was subjected to numerous tensile strength tests. These tests prove that the SP300 successfully withstands loads beyond 115lbs., significantly exceeding the weight of typical Single Duct Terminal Units.

All plastic components are Fire Resistant and meet UL 94-VO.

Control tubing is protected by grommets at the duct wall, and is securely fastened to the sensor.

The rugged construction features of the SP300 sensor ensure a trouble free installation and reliable operation.

Sensor X-Section

Optional removable SP300 Sensor is available and suggested for hospital grade jobs where sensor needs to be removed and periodically cleaned due to build up of lint.

Benefits of SCR• Time proportional control of the duct

heater maintains room set points more accurately than on/off or staged sys-tems, providing maximum comfort in the space.

• Energy Efficient – Because room set points are accurately maintained, under-shoot and overshoot is avoided, reduc-ing operating costs.

• Mechanical contactors are eliminated. Zero cross switching of the thyristor prevents electrical noise.

• Silent Operation – Solid state switching of the coil elements eliminates noisy contactors or the requirement for more costly mercury contactors.

• Controls can be specified compatible with pneumatic, electronic, or DDC.

Electronic Heating Controls

EMCThe Electronic Modulating Control (EMC) option is a Price exclusive feature which provides all of the advantages and benefits of SCR control plus an electronic flow sensor.

Benefits of Electronic Air Flow SensorThe air flow sensor responds to radiant heat of the heating element which, in turn, is influenced by the air flowing through the heater to dissipate the heat. The patented air flow sensor and associated electronic controller modulate the power to the heater, adjusting the heater’s capacity to match the air flow available. This unique concept allows the heater to respond exactly to the quantity of air flowing through it as well as safely shut down in case of a total loss of air flow.

Note: The air flow sensor overrides the temperature control to match the heating capacity to the air flow available.

Since the electronic flow sensor responds to radiant heat as opposed to duct pressure, it eliminates the problem of low air flow or duct static pressure switches, and ensures safe operation of heaters at flows as low as can be set by conventional controls.

Selection Guidelines

Electric Coil SelectionWhen selecting electric coils, the following points should be considered:

1. Once the design airflow has been determined refer to the appropriate airflow limits to select the size of unit required to deliver the specified air flow.

2. With size and airflow known, electric reheat capacity can be calculated. Refer to the electric coil selection procedure below for details.

Electric Coil Selection ProcedureThe selection of an electric coil for a single duct terminal unit requires the determination of the two components of the heat loss. One component is the heat required to satisfy the space load. The second component is the heat required to raise the temperature of the primary air to that of the space. This can be determined as follows, using the Electric Reheat Selection Chart and the equation as given below.

1. Locate the room heat loss on the MBH scale on the far left side of the chart. Convert to kW by moving horizontally to the right to the kW scale (1 kW = 3.413 MBH).

2. Calculate the kW required to heat the primary air to room temperature using the following equation:

kW = CFM x 1.08 x DT 3413

3. Add the kW value obtained in step 2 to the kW scale at the left side. Move horizontally to the right to the point where the kW value and the air flow volume intersect.

4. With the point of intersection from step 3, the air temperature rise (ATR), can be obtained by interpolating between the air temperature rise lines on the graph.

5. To verify the selection, sum the air temperature rise and the temperature of the primary air. The sum total should be less than 120°F.

3. With the heating capacity known, confirm:

a. Power Supply requirements from coil selection charts.

b. The minimum air flow require-ments are met (at least 70 cfm/kW), and that the discharge air temperature does not exceed 120° F.

4. Select coil options.

Reheat Selection Chart

How to Use the Chart

Selection Example

Select electric coil for a size 12" with a minimum airflow of 700 cfm. Space heat loss is estimated at 20 MBH and space design temperature is 70°F. The tempera-ture of the primary airflow is 58°F.

1. Space heat loss (20 MBH) = 5.9 kW.

2. Heat required to raise the temperature of the primary air:

kW = 700 x 1.08 x 12 = 2.65 kW 3413

3. Total heat required = 5.9 + 2.65 = 8.6 kW

4. Air temperature rise (ATR) = 40°F

5. Leaving air temperature = 58°F + 40°F = 98°F. Since the leaving air temperature is less than the recom-mended maximum limit of 120°F, the selection is satisfactory.

6. Select a suitable power supply from the Coil Selection Charts.

7. Verify minimum airflow require-ments are met. (Minimum 70 cfm/kW).

700 cfm = 81 cfm/kW 8.6 kW

5. Static pressure loss of the coil elements is negligible, therefore minimum pressure is equal to the basic unit values.
