NC levels presented in the Typical Selection Guide are based on typical attenuation values as outlined in AHRI Standard 885-2008, Appendix E. AHRI Standard 885-2008, Appendix E provides typical sound attenuation values for air terminal discharge sound and air terminal radiated sound. The typical attenuation values are recommended for use by manufacturers to estimate application sound levels.

In product catalogs the end use environments are not known and the factors presented in AHRI Standard 885-2008 are provided as typical attenuation values. Use of these values will allow better comparison between manufacturers and give the end user a value which will be expected to be applicable for many types of spaces.

Following is a detailed description of the typical attenuation values used to determine NC levels on page F62.

Radiated SoundTable E-1 of Appendix E provides typical radiated sound attenuation values for three types of ceilings: Type 1 – Glass Fiber; Type 2 – Mineral Fiber; Type 3 – Solid Gypsum Board.

Since Mineral Fiber tile ceilings are the most common construction used in commercial buildings, the attenuation values in the Typical Selection Guide are based on Type 2 – Mineral Fiber.

The following table provides the calculation method for the radiated sound total attenuation values based on AHRI Standard 885-2008.

insulation4. The ceiling has no significant penetration directly under the

unit.

Discharge SoundTable E-1 of Appendix E provides typical discharge sound attenuation values for three sizes of terminal units.

1. Small box – defined as a unit with discharge duct of approximately 8 in. x 8 in. [203 x 203] and capacity less than 300 cfm [142 L/s].

2. Medium box – defined as a unit with discharge duct of approximately 12 in. x 12 in. [305 x 305] and capacity between 300 – 700 cfm [142-330 L/s].

3. Large box – defined as a unit with discharge duct of approximately 15 in. x 15 in. [381 x 381] and capacity of greater than 700 cfm [330 L/s].

NC vs Sound Power Levels – Compare Them CarefullyPrice represents the sound performance data for the SPV/SDV series of single duct terminals in two manners.

The laboratory attained discharge and radiated sound power levels for each unit at various flows and inlet static pressures is presented in the Acoustical Data tables. This data is derived in accordance with AHRI Standard 880 and shows the 'raw' sound power levels of the terminal in the second through seventh octave bands with NO attenuation allowances. This data includes AHRI standard ratings which are on record with the Air-Conditioning Refrigeration Institute.

Price also offers this Typical Application and Selection Guide to assist you in selecting the proper size and configuration of terminal for your needs. The attenuation allowances listed are based on values suggested in AHRI Standard 885-2008, Appendix E. The suggested attenuation allowances are intended to be representative of typical jobsite construction. If your conditions differ significantly from these it is recommended you utilize the sound power level data on pages F68-F70 and the procedures outlined in AHRI Standard 885-2008.

If the NC levels listed in the Price catalog are being compared to other manufacturers’ cataloged NC information, a careful review of the other manufacturers’ attenuation allowances must be made. If allowances other than recommended AHRI Standard 885-2008, Appendix E are used, a fair comparison of NC levels cannot be performed.

Pressure Drop Explanation1. ∆Ps is the static pressure drop across the terminal unit from the

inlet to the discharge.2. Minimum ∆Ps across the unit is the pressure drop across the

terminal unit from the inlet to the discharge with the damper in full open position. The minimum ∆Ps must be maintained in order to supply the rated airflow through the terminal unit.

Minimum ∆Ps values are provided for the basic assembly only and for the basic assembly combined with accessories such as attenuator and hot water coils.

The minimum ∆Ps across the terminal unit and accessories does not include resistance of the downstream ductwork or diffusers. To determine the minimum inlet static pressure required to achieve rated airflow the downstream resistance must be added to the minimum ∆Ps.

3. ∆Pt is the total pressure drop across the terminal unit from the inlet to the discharge. Total pressure includes both the static pressure drop and velocity pressure drop. Velocity pressure drop is due to the reduced duct velocity at the terminal unit discharge.

4. NC at ∆Ps across the unit is the NC level produced by the terminal unit with the listed static pressure drop from the inlet to the discharge (∆Ps). The listed ∆Ps is the excess static pressure removed by the terminal unit damper.

Selection Procedure

The selection of the terminal unit will be based on the minimum and maximum primary airflows determined to satisfy the space requirements. The maximum flow is determined by the space cooling load while the minimum flow is determined form the ventilation rate per ASHRAE Standard 62 – 2004 or the space heating load.

Price single duct terminals are offered with inlet valve sizes ranging from 4" [102] round to 24”x16” [610 x 406]. Each inlet size has a specific air volume range based on the minimum flow which can be accurately controlled to the maximum flow which will maintain reasonable pressure loss and noise level. Recommended air volume ranges are cataloged for each inlet valve size. Usually several inlet valve sizes will accommodate a particular set of minimum and maximum design flows .

A common practice is to select the largest inlet valve size possible in order to reduce the terminal generated sound. While this practice may appear to reduce catalog noise levels this is not necessarily true. The larger size terminal will normally have a lower minimum operating pressure drop requiring the valve damper to throttle more at a given inlet static pressure. The more closed or pinched a valve damper is for a given inlet static pressure, the more sound it will generate. See Figure A for an example.

Another disadvantage of an oversized selection is equipment cost as a larger size unit is generally more expensive. All accessories such as reheat coils and attenuators of an oversized unit will add to this cost disadvantage.

Pressure independent terminals (VAV) need to control at both the maximum airflow as well as the minimum airflow. The recommended maximum and minimum flow rates are intended to allow any controller to properly resolve the airflow signal and provide the opportunity for control. It is possible when a damper is mostly closed (at low flows), the control accuracy may be degraded as the damper actuator is only using a fraction of the damper travel or stroke and small changes in damper position may generate significant changes in air volume

It is recommended that the terminal unit valve be sized for 75 to 80% of the rated air volume capacity. Minimum flow rates should be around 20% of the rated air volume for the most accurate level of control.

Should an inlet valve be oversized, another issue may arise if optional electric heaters are installed. At low flows, there may not be sufficient total pressure to activate and maintain the closure of the airflow safety switch, which can easily the to nuisance tripping of the thermal safety switch.

Minimum Inlet Static PressureIn order to size the fan system the minimum inlet static pressure at the terminal unit must be determined.

The minimum static pressure at the inlet of a single duct terminal unit includes the pressure drop across the unit, the pressure drop across any accessories, plus the pressure drop of the downstream ductwork and diffusers. The minimum static pressures of the terminal units and hot water coils are listed in the typical selection guide. The resistance of electric coils can be considered to be negligible. Providing higher static pressure than required at the terminal inlet will cause the valve damper to throttle more, increasing the terminal generated sound.

Single Duct Selection, Reheat The office zone in the following example consists of three offices, each measuring 15 ft (4.6m) long by 12 ft (3.7m) wide by 9 ft (2.7m) tall with a floor-to-floor height of 12 ft (3.7m). The offices are served by a single terminal unit mounted above the hallway ceiling. Design conditions for the zone will include two occupants in each room with a single computer with LCD monitor. The offices are all lit by T8 fluorescent lighting and the control temperature will be 75 °F (24°C) during the day and 65 °F (18°C) at night.

Space Considerations• Heatloadsourcesforeachofficespace: qex = Heat gain from exterior surfaces (Summer), estimated

and equipment (308 Btu/h) [90W] ql = Heat gain due to lighting, estimated at 6.82 Btu/h ft2

[21.5 W/m2] *This heat load should be calculated based on the

Then, determine the minimum outdoor air ventilation airflow:

where:Rp = the outdoor air requirement per person, 5 cfm [2.4 L/s]

(Table 6-1, ASHRAE Standard 62.1-2004).Ra = the outdoor air requirement per ft2 of floor space,

0.06 cfm/ft2 [0.3(L/s)/m2] (Table 6-1, ASHRAE Standard 62.1-2004).

Pz = Number of zone occupantsEz = the ventilation effectiveness, assumed to be 1.0 for a

mixing systemAz = (12)(15)=180 ft2

Az = (3.7)(4.6)=17 m2

Assuming that the air handling unit provides supply air at a ratio of 25% outdoor air and 75% recirculated air, the actual box minimum must be four times the value of Q(min,oa) above to meet the outdoor air ventilation requirements. Therefore:

Qmin = 4(Qmin,oa ) = 250 cfm

The heat loss from the space in the winter must also be considered. Taking the exterior heat loss to be -8 Btu/h/ft2 [25 W/m2], the heat loss on a winter night (no people/equipment, lights off) is found to be 1440 Btu/h [422 W] per office.

Assuming a reheat supply air temperature of 95 °F [35°C] and a room temperature of 75 °F [24°C]:

Since the required reheat airflow is less than the minimum ventilation airflow, the reheat flow rate will need to be equal to the unoccupied night air volume to properly heat the space in the winter. Assuming a desired heating supply temperature of 95 °F ,the reheat capacity can be calculated as:

Selecting an Electric Reheat Coil:The previous calculations have determined that 2.5 kW of reheat is required from the electric heater. In order to select this heater, two additional parameters must be known: the input voltage/phase to the heater, and the control method. If a single-stage heater of 480 volt, three-phase input power is assumed, the following calculations can be made in the AIO software.

A limiting factor in electric coil selection can be the current draw of the heater, which can be calculated as:

This agrees with the data in the example above. Generally, special considerations are required when coils draw more than 48 amps.

An additional point to consider: electric coils have a minimum flow requirement of 70 cfm/kW (33 L/s per kW). Failure to do so may result in hot spots along the coil, where repeated overheating may lead to thermal fatigue and eventual coil failure.

Single Duct Terminal Unit Selection:The first step in selecting a single duct terminal unit is to choose the inlet or valve size. This is generally dependent on the value of both the maximum and the minimum cooling airflow for the zone. Using the Price Terminal Unit Catalog and comparing inlet valve sizes vs. air volume ranges shows that the size 6 in. (152mm) and 8 in. (203mm) are in the desired range of operation.

The lowest inlet velocity that the single duct sensor can reliably and repeatedly control is based on a Vp signal of 0.02 in. w.g. (50 Pa). For an 8 in. (203mm) valve this is 132 cfm (62 L/s). This value is the lowest cfm that the terminal unit/controller assembly can reliably control, meaning that the unit minimum should be selected higher than this value to ensure the full minimum airflow is delivered to the space.

Note: these lower minimum cfm values for the various inlet sizes are based on data from the manufacturer of the flow sensor. A typical lower limit for the airflow velocity that will provide a strong pressure signal is 400 fpm (2 m/s).

Reheat Coil Selection:Many applications require the use of reheat coils on terminal units. These may be hot water, steam or electrical heating coils. These coils reheat the air when required to satisfy the space requirements.

Selecting a Hot Water Reheat Coil:Based on the calculations above, the zone requires 8.6 MBH at a reheat airflow of 200 cfm (94 L/s). Using Price’s All-In-One software (shown below), to determine the necessary coil (see below), a one-row coil flowing 0.79 gpm (0.05 L/s) will satisfy the MBH and LAT requirements for the supply air to the space. Since the calculation below is based on water at an EWT of 180 °F (82°C), other fluid types and different temperatures will alter the performance selection.

Additionally, the air-side and water-side pressure drops must be reviewed to ensure that the system equipment (AHU, water pump) will be able to handle them. This example results in an air-side pressure drop of 0.08 in. w.g. (20 Pa) at minimum cfm, and a water-side pressure drop of 0.4 ft. w.g. (1.2 kPa) at full fluid flow of 0.79 gpm (0.05 L/s). Typical practical limits for these parameters are 0.50 in. w.g. [124 Pa] (air-side) and 10.0 in. w.g. [2488 Pa] (water-side), and this performance selection is well within those limits.
