High Plume Dilution - Vektor Laboratory Exhaust System The Greenheck Vektor™ High Plume Dilution Blower (patented) employs a unique discharge nozzle design that entrains additional ambient air, diluting the exhaust effluent from the laboratory, which reduces exhaust contaminant concentration. More important, the addition of the ambient air increases the Vektor’s discharge windband mass flow and velocity, resulting in greater nozzle discharge momentum, displacing the diluted exhaust high above the roof.

How Vektor Technology Works... Laboratory exhaust is drawn into the Vektor fan (A). The exhaust is discharged into the Vektor induction nozzle and ambient dilution air is induced into the Vektor nozzle (B). The laboratory exhaust plus induced dilution air is discharged at high velocity to atmosphere (C).

AMCA 260 Air Test Procedure The following illustrations describe the procedure for determining the total laboratory exhaust fan discharge flow. The total discharge flow is the sum of inlet airflow and entrained airflow. The key requirement to AMCA 260 is the variable resistance box. This box allows the measurement of total discharge flow (Ps = 0 in. wg to simulate discharging the fan to atmosphere) at all points along its fan curve. Without the variable resistance box, the entrained airflow can only be measured at the free air point of its fan curve. The entrained airflow obtained can be used to calculate an effective plume height. Therefore, AMCA 260 certification is necessary to ensure the laboratory exhaust fan specified is providing the plume rise and entrainment submitted.

Effective Plume Height It is important that the exhaust plume height be great enough to avoid re-entrainment of exhaust air and to disperse the exhaust. The effective plume height should be used when analyzing design issues. The effective plume height (he ) is the physical height of the fan system (hs ) plus the plume rise (hr ), found from the equation below. The effective plume height is calculated using the following equation*: he = hr + hs

Adjusting Plume Height Adjusting the fan system to have additional throw or plume height is achieved by increasing the volume of air through the discharge nozzle. Simply changing the drive pulleys will increase fan speed and volume capacity, thus boosting flow momentum. The additional air through the fan comes from an increase in lab exhaust or an increase of air through a bypass air damper. Utilizing a bypass air damper to increase both dilution and mass flow of the exhaust air can optimize plume rise. Increased mass flow improves momentum and carries the diluted exhaust higher. The plume height can also be adjusted by changing nozzles. A higher velocity nozzle results in higher outlet airflow, which in turn results in higher plume rise.

Density Correction Factor Equation DCF = ((T + 460)/530) x 1.037(E / 1000) DCF = Density Correction Factor T = Temperature (degrees F) E = Elevation above sea level (feet) Air Density (lb/ft3) = 0.075 / DCF

Effects of Air Density When selecting a fan to operate at a non-standard air density using standard air density tables and curves, corrections must be made to static pressure and brake horsepower. At higher than standard elevations and temperatures, air density will be lower than standard. Therefore, static pressure must be determined at standard density that will equate to the specified static pressure at the operating density. Since standard air density is greater than operating air density in this instance, one would expect the corrected static pressure to be greater than the operating static pressure. The following example shows how to select a Vektor-MD Size 30, 85% Wheel Width, Low Velocity (LV) Nozzle for 17,000 cfm, 4 in. wg, 1000 ft. elevation, and 125°F temperature. 1. Since the volume exhausted by the system is not affected by density, cfm remains 17,000. 2. Select the correction factor from the chart for 1000 ft. elevation and 125°F. Correction factor is 1.14. 3. Multiply specified static pressure (4 in. wg) by the correction factor (1.14) to determine standard air density equivalent static pressure. {4 in. wg x 1.14 = 4.56 in. wg} 4. Using the performance curves, enter 17,000 cfm and 4.56 in. wg of static pressure. 5. At the intersection of 17,000 cfm and 4.56 in. wg static pressure, the fan rpm is approximately 1450 rpm and Bhp is 20. 6. Since the horsepower selected refers to standard air density, this must be corrected to reflect actual Bhp at the lighter operating air. Remember, horsepower is less at a lower air density. Divide the Bhp required (20) by the correction factor (1.14) selected previously to determine the Bhp at the new operating conditions. 20/1.14 = 17.5 Bhp. This would require a minimum motor size of 20 hp.

Vektor-MD Selection: AMCA 260 Inlet Airflow Curves Every laboratory or fume exhaust application has a unique set of criteria that must be evaluated in order to determine the most effective exhaust system. The selection of a Vektor-MD requires the lab exhaust volume (effluent) per fan along with a determination of the external static pressure. Other considerations when making fan selections include: sound requirements, electrical limitations, size constraints, and the effective plume height. 3) Determine fan rpm

1) Determine the laboratory exhaust requirements •

Determine the lab exhaust volume per fan.

•

Determine the external static pressure at the system inlet.

•

Locate the fan operating point (the intersection of the required airflow and static pressure) on the inlet airflow in Figure 1.

In this example, the operating point is 17,500 cfm at 4 in. wg.

The belt drive fan rpm can be estimated by comparing the operating point to any of the solid fan rpm curves and in this example, the operating point falls on the red 1360 rpm curve.

Direct drive fan selections must use the 50 or 60 cycle rpm curves (yellow or blue curves).

•

Determine the brake horsepower by comparing the operating point to the dashed brake horsepower curves.

In this example, the brake horsepower is above 15, but slightly less than 20 hp. A minimum of a 20 hp motor is recommended for this selection.

B

Bypass Air Plenums - Estimated Pressure Drop • Variable volume lab exhaust systems require a bypass air plenum and damper. • Greenheck’s Computer Aided Product Selection (CAPS) software, automatically adds external system static pressure to account for the bypass air plenum and isolation damper.

C

2) Select the appropriate Vektor-MD A

•

Select Vektor-MD fans with a minimum nozzle velocity of 3,000 feet per minute (ANSI Z9.5 and ASHRAE lab design guidelines), which is represented by the green vertical line in Figure 1.

4) LV, MV and HV Nozzles

All Vektor-MD curves indicate the minimum cfm necessary to meet this minimum velocity.

Each fan size is available with Low Velocity (LV), Medium Velocity (MV) or High Velocity (HV) nozzles.

•

Multiple nozzles allow for the optimization of brake horsepower, plume rise and acoustic performance.

Note: For most applications, the LV or MV nozzles are recommended in order to limit the operating brake horsepower. HV nozzles are available for applications that require the highest plume rise.

Vektor-MD Selection: AMCA 260 Outlet Airflow Curves igure 2 below illustrates the new AMCA 260 fan curves. Each fan has two performance curves associated with F each rpm: the red curve is the flow through the fan and the blue curve directly to the right is the windband exit volume. These curves have been connected with shading. 1) Determining windband exit volume •

2) Determining windband velocity, dilution ratio and effective plume height ach Vektor-MD size and nozzle combination has a unique set of equations to determine the nozzle velocity, E dilution ratio, and effective plume height. Since the operating point is 17,500 cfm at 4 in. wg, calculations are as follows for a Vektor-MD Size 30-LV. Windband Exit Volume = 30,000 cfm Nozzle Velocity = 17,500 cfm/5.45 ft2 = 3211 ft/min Dilution Ratio = Windband Exit Volume/Fan Inlet Airflow = 30,000 cfm/17,500 cfm = 171%

) )

+ 16 + 16 = 45 ft

ote: Effective Plume Height includes the fan height of 16 ft. as indicated in the dimensions section of N this catalog.

Determining Inlet and Outlet Sound Along with the fan rpm, it is necessary to know the fan percent wide open volume (%WOV). The %WOV can be calculated using the equation posted adjacent to each fan curve. %WOV (Vektor-MD-30-LV) = (cfm x 100) / (rpm x 17.6). For this example, the %WOV is 73%. The sound power and sound pressure can be determined through linear interpolation between sound data provided at 1170 rpm and 1360 rpm.

Vektor-MD Selection: Reading Fan Curves There are several variables in selecting an appropriate Vektor-MD system including % wheel width and nozzle size. These factors will affect the required brake horsepower, fan RPM, and entrained air. As a general rule, the low velocity nozzle will require less brake horsepower than the high velocity nozzle, but entrained air and plume rise will be slightly less. Higher pressures can be achieved by using reduced % wheel widths. Belt drive units are available in 100%, 85%, and 70% wheel width. Direct drive units are available from 100% - 50% wheel width in increments of 5% (i.e. 95%, 90%). Step 1: Identify necessary laboratory effluent (CFM), plume rise (ft), and % dilution. Enter the Vektor-MD quick select chart located on page 8 and identify unit sizes that can accommodate application specifications. Also determine if belt or direct drive is desired. For direct drive units, only the blue RPM curves are available for 60 cycle power and gold curves for 50 cycle power. Belt drive units are capable of operation at any RPM within the max fan class RPM (the last RPM curve). Step 2: Using the guidelines above, locate fan size that generally suits specifications. Calculate necessary system pressure including isolation damper, bypass air plenum, and system drop. (See below) Enter the fan curve with the desired performance specifications: airflow (CFM), pressure (in. wg), and nozzle outlet velocity (fpm). This yields horsepower (HP) and RPM at the fan operation point. If the given point has a close proximity to a horsepower curve, the next larger motor horsepower should be selected. Pressure Drop Variable volume lab exhaust systems and systems that require additional bypass air, require a bypass air damper and plenum. When calculating necessary pressure, 0.2 in. wg must be added to the external system static pressure to account for the bypass air plenum. Add 0.15 in. wg if the system includes an isolation damper.

Volume (m /hr x 1000) NOTE: All plots represent fan operation at standard air (70°C at sea level). ANSI Z9.5 specification requires a 3,000 fpm minimum nozzle outlet velocity.

• Locating this point on the curve (A), a 20 HP motor is needed to operate at 1360 RPM and provides 3,211 fpm nozzle velocity. • Using the %WOV equation provided with the Vektor-MD size 30, 100% wheel width, LV nozzle air data chart, the %WOV can be calculated: %WOV = (17,500 x 100) / (1360 x 17.6) = 73 % WOV

How to Calculate Sound Performance Once a Vektor-MD low velocity fan has been selected that meets performance specifications, use the following procedure to attain sound data for the specific fan rpm and percent wide open volume (%WOV). Interpolation will be used to determine the eight sound power levels, the total sound power (Lw A) and sound pressure (dBA) rating. The Vektor-MD Size 30, Low Velocity Nozzle is operating at 1000 rpm and 68% WOV. Viewing the size 30 sound power table, interpolation between 60 and 80% WOV is needed to find values for 68% WOV.

Example of Sound Performance:
