Air Circulation in Large Spaces

The Problem…

The Problem

1. Problem – Wasted Energy! In the heaFng season, warm air is trapped at the ceiling and never makes it to where people are working.

The Problem

2. Problem – Uncomfortable Employees! In the cooling season, high temperatures and humidity make employees uncomfortable and decrease producFvity.

3. Problem – Increased Moisture!

•  Moisture damages product and packaging. •  Metals rust and cardboard boxes are ruined. •  CondensaFon on floors makes them slippery for people and machines.

The Problem

The Problem

…High Speed Floor or Wall Fans….

•  Generate large volumes of Noise. •  Are potenFal trip hazards. •  Can force debris into the air. •  Can be knocked over and damaged. •  Cover very small areas. •  Air easily blocked by obstrucFons. •  Take up floor space when in use. •  Waste Energy!

Air Circulation in Large Spaces

The Solution…

The SoluAon-‐BladeTec HVLS Fans

BladeTec High Volume/Low Speed (HVLS) Ceiling Fans!

What are HVLS fans?

• Large diameter ceiling fans-‐2440 mm (8’) to 7320 mm (24’)

• Moves large volumes of air-‐23,600 Liters Per Second (50,000 CFM) to 186,500 L/s (395,000 CFM)

• Covers up to 29 M (95 a) in all direcFons. 2641 Sq M(28,400 Sq Ft)

• Operates at low speeds 10-‐152 revoluFons per minute (rpm)



• HeaFng large spaces is difficult and expensive.

• HeaFng systems oaen overheat the ceiling.

• Warm air gets trapped at the ceiling.

• OverheaFng results in addiFonal energy expenses.

BladeTec HVLS Fans circulate the air and help maintain constant temperatures-‐Floor to Ceiling!


BladeTec HVLS Fans circulate the air and improve the comfort, producAvity and the health of

Customers and Employees!

• High temperatures and humidity make employees uncomfortable and decrease producFvity.


Corrosion on Steel Coils due to Moisture

• Moisture and smells exist in areas that are poorly venFlated.

• Moisture damages product and packaging.

• Metals rust and cardboard boxes are ruined.

• CondensaFon on floors makes them slippery for people and machines (SweaFng Slab Syndrome).

BladeTec HVLS Fans circulate the air over floors and product to keep smells, moisture and

CondensaAon to a minimum!


BladeTec HVLS Fans supplement most air condiAoning systems. Allows many applicaAons to raise the thermostat seTng to reduce energy costs!

• Cooling large spaces is difficult and expensive!

• According to most public uFliFes and the US Dept of Energy, many buildings set air cooling temps too low.

• For each degree you raise your thermostat sedng, you reduce seasonal cooling costs by 7% -‐10%.


• HeaFng systems: BladeTec Fans DestraFfy the air and supplement blowers in exisFng ductwork.

• Air CondiFoning: Raise set-‐point of thermostat and use HVLS fans to create an air speed which lowers the effecFve temperature.

BladeTec HVLS Fans can be used with exisAng HVAC Systems!

ApplicaAons

Construction

ConstrucAon

CompeFtor Fan with 10 Blades

It’s all in the Blade…Technology! •  It is the shape, not the number of blades that generate the large volume of air movement.

•  Our blade design has a complex contoured shape that varies along its length. Narrow at the Fp, where blade velocity is high and widened at the hub where blade velocity is lower.

•  Maximum air volume is delivered when there is a consistent amount of air movement across the enFre diameter of the fan.

•  This blade design is impossible to produce by extrusion. Extruded blades do not provide this efficient, consistent air movement and they require a greater number of blades to help compensate.

•  The Fps on the end of the blade reduce the noise and create more air movement at the perimeter of the fan.

ConstrucAon

Resilient Blade-‐to-‐Hub ConnecAon

• Rubber bushings absorb the upward movement of the blade when in operaFon.

• Blade is seated into a secure posiFon on the hub arm and locked into place with hardware.

CompeFtor fans have metal to metal connecFon. They do not

use rubber bushing for vibraFon and noise control

ConstrucAon

Balanced Hub and Blades

•  The hubs and blades are rotaFonally balanced at the factory.

•  They are ideally suited for your fan applicaFon and will never require adjustment.

•  They are weighted at the factory to spin in balance (just like wheels on a vehicle)

Design

Design

Designing a HVLS Fan System

1.   Iden>fy the Applica>on

2.   Determine the customers objec>ve.

3.   Determine the Area(s) of concern within the space.

4.   Fan Selec>on-‐Size, Type & Number of fan(s)

5.   Locate Fan(s) within Space.

Design-‐Understanding the ApplicaAon

1) IdenAfy the ApplicaAon.

What is the ApplicaFon?

Applica>on DistribuFon Center What do they distribute? Where are the loading docks?

Manufacturing Facility What do they Manufacture?

Warehouses What do they warehouse? Where are the loading docks?

AthleFc FaciliFes What type of acFvity

Airports Is this a terminal or a hangar?

Retail Type of retail outlet? Store, Restaurant?

Arenas Is this a sporFng arena, Theater, ConvenFon Center or Religious facility?

Hotels Is this for the lobby or an indoor swimming pool?

Auto Dealers Is this for the showroom or the maintenance shop?


Objec>ve Descrip>on Cooling

Used for effecFve cooling. The air velocity makes the occupants perceive a cooler temperature.

HeaFng (DestraFficaFon)

Used for mixing air verFcally from ceiling to floor (typically known as air destraFficaFon) and/or mixing air horizontally from one building area to another.

Air CondiFoning Used in combinaFon with tradiFonal air condiFoning systems, making cooling more efficient.

Disperse Humidity Used to disperse pockets of humid air or higher heat caused by some manufacturing processes.

Air CirculaFon Used to increase air circulaFon within a facility for drying floors, raw materials and product.

2) Determine the Customer’s ObjecAve.

What are they trying to achieve in the space?


Objec>ve Descrip>on LocaFon Which specific locaFon in the facility is the customer wanFng to address?

Dimension What are the dimension of the area that needs to be addressed?

Number of People How many people are in the area of concern at any given Fme?

MulFple Needs Does the customer have different requirements in various different areas of the facility?

Drawings

Does the customer have a set of drawings or plans?

ObstrucFons Are there any walls, mezzanines, equipment, etc., in the space that could obstruct air flow or blade movement?

3) Determine the Areas of Concern within the Space

Where do they want the air?

Design-‐Fan SelecAon

Perceived Range of Temperature Drops BladeTec fan layout is based on the concept of how air velociFes can produce a perceived range of temperature drop at varying distances from the center of the fan.

Areas of Influence. Concentric circles spreading out from the center of the fan represent average air velocity, distances and perceived temperature drops.

The benefit of the BladeTec selecAon methodology is a more scienAfic analysis of the relaAonship between fan diameter and perceived temperature change.

4) Fan SelecAon-‐Size, Type and Number of Fans


Each BladeTec model has its own Area of Influence. The larger the fan, the larger the Area of Influence.

4) Fan SelecAon-‐Size, Type and Number of Fans


Considera>ons

Place fans to minimize air flow obstrucFons and provide the greatest cooling effect for the most people

When possible, keep blade Fps at least two fan blade lengths from walls or solid obstrucFons

BladeTec Fans have minimum overhead clearance requirements based on fan diameter

Center fans in light or sprinkler grids when possible (example: a 3660 mm diameter fan fits into a 3050 mm grid)

5) Place Fans within Space

•  If you are mounFng to support angles that span building joists, you will also need a drill and a ½" drill bit.

InstallaAon

•  Mounted fan directly to the beam with the brackets provided.

•  Clamp the brackets around the beam as shown using the holes in the upper beam mounFng bracket that are closest to the edge of the beam.

•  For beams that are larger than the bracket, clamp the bracket on one edge of the beam and drill holes through the beam to bolt the other side securely.

•  Use only grade 8 hardware.

Use a level to ensure the Drop tube is hanging verAcal.

I Beam MounAng

InstallaAon

•  When using a support channel to span (2) building joists you must use material that will securely support the fan.

•  Two (2) pieces of 76 mm x 76 (3" x 3" x .25“) angle is recommended.

•  These angles should be mounted in a way that the fan can be hung using the standard I-‐beam mounFng bracket.

•  The angles should be securely mounted to the building joists to ensure the angles cannot move.

•  Never mount the fan to only one building joist. One joist will not provide the rigidity and support necessary for the fan during operaFon.


Ceiling Truss MounAng

InstallaAon

•  The truss kit supplied by BladeTec is designed to make the installaFon of the fan easier.

•  The two formed angles span exisFng building trusses.

•  The brackets are used to secure the angles to the building trusses while sedng the gap between the angles for the drop tube.

•  There are several mounFng posiFons cut into the angles to allow for flexibility in posiFoning the fan.

•  When the truss kit is ordered from BladeTec, the standard I-‐beam ceiling bracket will not be provided.

•  Never mount the fan to only one building joist. One joist will not provide the rigidity and support necessary for the fan during operaFon.

MounAng Clearance and Adequate Air Flow If the ceiling’s support structure is a solid beam or solid channel, all measurements must be taken from the bomom of the beam.

If the ceiling support structure is an open-‐web design, all hanging dimensions can be taken from the underside of the ceiling.

If the roof is pitched, this must be accounted for above the Fps of the blades.

Solid Beam Design Underside Beam to Fp of Fan Blades

Open-‐web design Underside ceiling to Fp of fan blades

Pitched Roof Design Observe Min Distance to Underside of Roof

InstallaAon

MounAng the HVLS Fans & Types of InstallaAons

•  The weight of the fan that will be suspended from the ceiling is approximately 136.4 kg (300 lbs).

•  The standard blade design on the BladeTec Fans are angled upward to provide improved airflow.

•  Air pressure causes the blades to move upward to their operaFng posiFon.

•  Measure the distance to possible obstrucFons and mount the fan accordingly to ensure the blades will have proper clearance in all areas when the fan is running.

InstallaAon

Motor Bracket Afachment

•  The motor bracket amaches to the Drop tube with (2) grade 8 bolts, washers and lock nuts.

Grade 8 Bolts Motor Brackets

Drop Tube

•  When an extended down drop tube is used, the smaller square tubing will telescope inside the larger square tubing.

•  The brackets on the top of the motor bracket are bolted in slots to allow the larger tube to bolt to the top of the motor. The 3" x 3" tube should always bolt to the ceiling bracket.

InstallaAon

•  These cables support the fan to the ceiling if one of the bolted joints were to come loose.

•  Cables are included with this kit to wrap around the bolted brackets at the ceiling and the top of the extension tube.

•  A second cable should be wrapped through the bomom of the extension tube and through the top of the motor housing.

•  When installing with adjustable length extension tubes, a third cable should be used to secure the center bolted joint of the extension tubes.

Commercial

Industrial

Safety Cables

InstallaAon

•  Cables are included with the kit to amach the fan bracket back to the ceiling in (4) locaFons.

•  These cables will help to stabilize the fan for any situaFons which may cause the fan to Flt and impact a ceiling joist or other object.

StabilizaAon Cables-‐Industrial

InstallaAon

•  The fan blades are set in place on the fan hub by raising the blade above the arm of the hub and allow the blade to slide into the slot on the hub.

•  Each fan blade is amached to the hub with a 1” bolt provided.

•  Using a torque wrench with a ¾“ drive extension, Fghten the bolt to 200 C per lb (271 NM).

•  When properly Fghtened the blade will Flt upward from the hub at approximately 6 degrees.

•  Clean each blade with a paper towel to remove fingerprints and dirt before the blades are installed.

FAN LEVELING It is important to level the fan hub after blade attachment. Level the hub by holding a level across the center of the hub in all directions.

Make fine adjustments with the stabilization Cables.
