Motor Starting Torque

When selecting a motor for a centrifugal fan, the motor must be capable of driving the fan at operating speed and also capable of accelerating the fan wheel, shaft and drive to the operating speed.

The fan performance tables and curves in this catalog show the brake horsepower required to operate the fan once it is brought to operating speed. For applications requiring a large air volume at a low static pressure, the BHP required at the fan’s operating RPM may not be sufficient to initially start the fan. If the time required to bring the fan to speed is excessive, the motor winding insulation can be damaged due to excessive temperature rise and the life of the motor seriously affected.

For a belt drive fan, the required motor starting torque capability can be expressed by the following formula:

FRPM =

MRPM =

V-Belt Drives

Constant Speed Drives

Advantages of constant speed drives include low vibration levels, ease of assembly and low cost. Fan speed changes can be accomplished in most cases simply by changing the motor pulley.

Constant speed drives are recommended over variable speed drives for applications that require motors 15 HP and larger, and all applications requiring 3600 RPM motors.

Variable Speed Drives

Variable speed drives allow the fan speed to be changed by adjusting the pitch diameter of the motor pulley. The power to the fan must be off and locked out, and the belts must be removed before manually adjusting the variable pitch pulley.

Effect of Air Density — High Suction at Fan Inlet

The density used for fan selection is that which is measured at the fan inlet. When the inlet total pressure exceeds 10 inches in suction, the density at the fan inlet should be corrected by the following values. These values should be multiplied to the fan static pressure and the result used for the proper fan selection. With suction pressures less than 10 inches, this correction is typically ignored.

Inlet Vane Performance

As inlet vanes are closed, they impart a spin to the airflow in the direction of wheel rotation and reduce airflow, static pressure and brake horsepower as shown in the graphs below. The graphs show how CFM, static pressure and brake horsepower are affected as inlet vanes are modulated from 100% open to 0% open in a typical variable air volume system. Graph 3 provides RPM and BHP correction factors for fans equipped with inlet vanes.

Effect of Air Density – Temperature and Elevation

Ratings in the fan performance tables and curves of this catalog are based on standard air (clean, dry air with a density of 0.075 pounds per cubic foot, barometric pressure at sea level of 406.75 inches wg, temperature of 70°F). Selecting a fan to operate at conditions other than standard air requires an adjustment to both static pressure and brake horsepower.

One cubic foot of air has a constant volume regardless of temperature or elevation. However, air density changes with non-standard temperature or elevation. Therefore, when selecting a fan to operate at a non-standard air density using standard air density tables and curves, corrections must be made to parameters affected by air density. These parameters are static pressure and brake horsepower.

For example, a size 30 BISW centrifugal fan is to deliver 16,500 CFM at 8.1 incheswg static pressure. Elevation is 2000 feet, temperature is 150°F.

The 8.1 inches wg static pressure refers to the static

( p

pressure at the operating air density, in this case at 2000 feet, 150°F. Intuitively, we realize that at higher than standard elevations and temperatures, air density will be lower than standard. Therefore, we must determine what static pressure at standard air density will equate to 8.1 inches wg static pressure at our operating density. Since standard

air density is greater than operating air density in this case, we would expect the corrected static pressure to be greater than the operating static pressure.

The accompanying table gives air density correction factors for non-standard temperatures and elevations.

The example below shows the relationship of fan performance at sea level and

at 2000 ft. elevation and 150°F.

Example:

The following example shows how to properly select the fan described above:

1. Since the air volume delivered by the fan is not affected by density, airflow remains 16,500 CFM.

2. Determine correction factor from chart for an elevation of 2000 feet and air temperature of 150°F. The correction factor is 0.808.

3. Divide the specified operating static pressure by the correction factor to determine the standard air density equivalent static pressure. Corrected static pressure = 8.1 inches wg ÷ 0.808 =

10.0inches wg static pressure.

4. Refer to the fan performance table for a 30 BISW. At 16,500 CFM and 10.0 inches wg static pressure: Fan RPM = 1790, BHP = 35.7

5. 1790 Fan RPM is required to produce the desired performance.

6. Since the horsepower selected refers to standard air density, this must be corrected to reflect actual BHP at the lighter operating air. Operating BHP = Standard BHP x 0.808, or 35.7 x 0.808 = 28.8 BHP.

If a fan is selected to operate at high temperatures, the motor must be of sufficient horsepower to handle the increased load at any lower operating temperature where the air is more dense. Assume the air entering the 30 BISW fan at start-up is 0°F. For 0°F and 2000 feet elevation, the air density correction factor is 1.071

BHP at 0°F = 35.7 x 1.071 = 38.2, therefore, a 40 HP motor is required.

Effect of Installation on Performance

Ratings presented in the performance tables and curves of this catalog were derived from tests made in accordance with AMCA Standard 210 — “Laboratory Methods of Testing Fans for Ratings.”

Inlet Spin

Turning

Vanes

The AMCA test procedure utilizes an open inlet and a straight outlet duct to assure maximum static regain.

Any installation with inlet or discharge configurations that deviate from this standard may result in reduced fan performance. Restricted or unstable flow at the fan inlet can cause pre-rotation of incoming air or uneven loading of the fan wheel yielding large system losses and increased sound levels. Free discharge or turbulent flow in the discharge ductwork will also result in system effect losses.

Static pressure losses due to inlet and discharge conditions can be expressed in terms of system effect factors. The static pressure for selection of the fans equals the system static pressure plus the system effect factor.

Some common inlet and discharge conditions which affect fan performance are:

Non-Ducted Inlet Clearance

Installation of a fan with an open inlet too close to a wall or bulkhead will cause reduced fan performance. It is desirable to have one fan wheel diameter between the fan inlet and the wall.

Inlet spin is a frequent cause of reduced fan performance. The change in fan performance is a function of the intensity of spin and not easily defined. The best solution is proper duct design and airflow patterns.

Discharge Duct Turns

Duct turns located near the fan discharge should always be in the direction of the fan rotation.

Fan performance is reduced when duct turns are made immediately off the fan discharge. To achieve cataloged fan performance there should be at least three equivalent duct diameters of straight ductwork between the fan discharge and any duct turns. Curve#4

Installation of a duct turn or elbow too close to the fan inlet reduces fan performance because the air is loaded unevenly into the fan wheel. To achieve full fan performance there should be at least one fan wheel diameter between the turn or elbow and the fan inlet. Curve #1 shows the system effect factor when less than one diameter is provided. Note: Use of an inlet box in lieu of a turn or elbow significantly reduces system effect.

AMCA Licensed Ratings

Sound tests of Model BISW and AFSW were conducted in Greenheck Fan Corporation’s AMCA Accredited sound laboratory in accordance with AMCA Standard 300. Inlet and outlet sound ratings comply with AMCA Publication 311, qualifying these models to bear the AMCA Seal for Sound and Air Performance. The sound power levels published here can be compared directly with those of other similarly rated fans, or used as a baseline to determine sound levels in occupied spaces.

The sound data in this brochure is the result of extensive testing, which included both inlet and outlet sound tests on single-width centrifugal fans. Typically, fan manufacturers publish only inlet sound for single-width fans. The assumption they make is that outlet sound is identical to inlet sound. Sound data based on this assumption is simply not accurate enough for today’s sound sensitive installations. This assumption also ignores duct end corrections for outlet sound.

Test Methods

AMCA Standard 300 clearly defines methods used to test fans in a reverberant sound test room. The reverberant room is specifically designed to allow sound waves to be dispersed evenly throughout the room. The walls have a hard surface that reflects sound and are positioned to prevent resonances which could result in quiet areas within the room.

Sound power cannot be directly measured. The test method is based on a Reference Sound Source (RSS) substitution for determining fan sound power. The RSS is a laboratory calibrated device which has a known sound power output level. The test fan is installed as shown below. The RSS is energized and the sound pressure levels in the reverberant room are recorded. The fan is then operated without the RSS and the fan sound pressure levels are recorded for various points of operation. Since the sound power levels of the RSS are known, the substitution method is used to determine the sound power levels of the fan. This method is illustrated in the following example.

Outlet Sound – Duct End Corrections

This correction accounts for sound that is reflected back into the duct where there is an abrupt termination of the duct.

AMCA Standard 300 requires that outlet sound power for fans with ducted outlets include Duct End Corrections. These corrections account for any sound power that may be present in the duct but is not measured in the reverberant room, because it is reflected back into the duct at the discharge.

Duct end corrections are included in all outlet sound power ratings.

Tolerance and Application

The certification process in AMCA Standard 311 calls for a precertification test to verify original test results. Check tests are also required every three (3) years for each model licensed. Test data must agree with the published sound power within the following tolerance levels:

Octave Band 1 2 3 4 5 6 7 8

Center Frequency (Hz)

Tolerance

63 125 250 500 1000 2000 4000 8000

+6 +3 +3 +3 +3 +3 +3 +3

These tolerance levels are a good indication of the variance that could occur from one fan or test setup to another. Once installed however, there are many other factors that can affect the sound power generated by a fan.

The lower frequencies (below 125 Hz) are greatly affected by vibration. Fan wheel balance, motor balance, drive alignment, etc., all affect the vibration level of the fan and can increase sound power in the 1st and 2nd octaves. When ducts are not properly isolated from the fan, these vibrations can be transmitted into the ducts, which can generate additional low frequency sound.

Sound power generated by a fan can also be influenced by system effects. System effects are pressure losses caused by inlet or outlet restrictions, or other conditions causing non-uniform airflow at the inlet or discharge of a fan (see AMCA Publication 201). Examples include inlet or outlet elbows too close to a fan, restricted inlets and fan accessories. While system effects can prevent fans from reaching their designed air performance, they can also result in increased sound power levels. Typically, system effects cause pressure fluctuations which influence the lower frequencies. Poor inlet conditions can also greatly increase sound levels at the blade pass frequency (BPF). The blade pass frequency refers to how often a blade or wheel fin passes a stationary location of the housing and can be calculated using the following equation:

Per AMCA: Blade Pass Frequency

BPF (Hz) =

NOTE: All BISW and AFSW wheels have nine blades.

Sound is becoming increasingly critical for most fan installations. Greenheck employs extensive research and testing to provide sound data that is as thorough and accurate as possible. However, sound pressure levels in occupied spaces are affected by the acoustical qualities of the space, distance from source to receiver, etc. Therefore, published sound power data can be used only as a baseline for determining the resulting sound pressure levels an occupant hears. While Greenheck provides products which meet published sound power levels, no manufacturer can be responsible for poor installations or system designs beyond their control. For further information on installation practices, see AMCA Publication 201, “Fans and Systems”.

An important point to remember when manually selecting a centrifugal fan is that more than one fan is available to meet the desired performance (CFM and Ps). Selection criteria such as unit size, efficiency, speed, outlet velocity, horsepower, or construction material may also dictate which fan is chosen.

Performance certified is for model BISW Arrangement 1, Installation Type B: free inlet, ducted outlet. Performance ratings do not include the effects of appurtenances (accessories). Power rating (Bhp) does not include transmission losses.

Fan Selection Procedure

BISW-36

STEP 1

Enter the performance table with the desired CFM and Ps. Obtain the fan RPM, BHP and Class.

EXAMPLE For this example, we will use 19,100 CFM at 4.0 Ps. This gives us a fan RPM of 995, requiring 17.2 BHP, with Class I construction.

NOTE: If your specific fan selection requires inlet vanes or if the fan operating point is not at standard air (70°F), refer to the inlet vane and air density correction factor tables found on pages 5 and 6.

STEP 2

Enter the Fan Curve with the desired CFM and Ps. Obtain the fan operating point, % WOV, Motor HP and verify fan class by curve shading.

EXAMPLE For this example, the fan operating point is at 60% WOV using a 20 HP motor.

NOTE: This motor size can be compared to the Maximum Open Frame Size chart (E) found above the performance table.

STEP 3

Enter the Fan Sound Table with the Fan RPM from the performance table and the % WOV from the fan curve. Obtain the eight octave ratings for inlet (L and Outlet (L

) Sound Power.

EXAMPLE For this example, the eight octave ratings can be calculated by interpolating between the data circled in the table.

NOTE: The exact % WOV for your desired performance can be found using the equation above the Sound Power tables if it is not published. The eight octave ratings can then be found using the interpolation instructions found in the Sound Performance section on pages 8 and
