Air-Handling Units

A make-up air unit provides replacement air. The purpose of a make-up air unit is to replace the air exhausted from a space by general ventilation, process equipment, heaters, and other HVAC equipment. By replacing the air, the building is brought to a neutral or predetermined building pressure.

DIRECT AND INDIRECT GAS-FIRED AHUs


Canada Blower makes two primary gas-fired AHU types: direct gas-fired and indirect gas-fired.

DIRECT GAS-FIRED AHU

A direct gas-fired AHU has a gas burner installed directly in the outside makeup-air stream. The products of combustion (carbon dioxide [CO2], carbon monoxide [CO], nitrogen dioxide [NO2]) are discharged directly into the makeup air stream and supplied to the building area.

INDIRECT GAS-FIRED AHU

An indirect gas-fired AHU has a sealed combustion chamber where all products of combustion are discharged through a flue to the outside environment and no products of combustion are discharged within the make-up air supplied to the building. Such equipment also frequently is utilized for recirculating-air applications.

DIRECT-GAS-FIRED-AHU COMPONENTS

Though simple in principle of operation, direct gas-fired AHUs have sophisticated burner-control systems. Unit sizes range from 1,000 cfm with a heating capacity of 80,000 Btuh to 100,000 cfm with a heating capacity of 15 million Btuh. Direct-gas-fired-AHU components usually include housings, supply fans, outside air intake hoods, intake dampers, filters and burners.

AHU HOUSINGS

AHU housings are made of galvanized or aluminized steel. Access panels are provided to access dampers, filters, burners, and fans / motors. AHUs located outside are provided with a sloped roof and standing seam joints.

SUPPLY FANS

Fans typically are double-width double-inlet (DWDI) with forward-curved or backward-inclined blades. Fans can come with open drip-proof (ODP) or totally enclosed fan cooled (TEFC) motors. The most typical external static pressure in the 2- to 3-in.-wg range. Because most outside istalled air handling units can operate below 0°F, fan motors and bearings are rated to handle lower temperatures. For applications that require supply-air temperatures higher than 110°F, the motors and fan bearings are rated for maximum design operating temperatures when placed in draw-through configurations.

INTAKE DAMPERS AND HOODS

Outside air intake hoods or weather hoods are designed for an installation specific location and usually provided with bird screens. Outside-air intake isolation dampers are furnished to prevent cold air from dropping through a unit into a warm building and warm air from escaping through a unit during winter months, when it is not in operation. Low-leakage parallel blade isolation dampers are most standard. The fan discharge is located at the opposite to isolation-damper position.

FILTERS

A filter cabinet normally has 30/30 filters in a V-bank configuration to increase filter area and reduce static-pressure drop across the filters. Higher-efficiency filters are used on application.

BURNERS

A burner consists of a cast-iron or aluminum pipe assembly with drilled gas orifices. The fuel-air mixing is controlled by perforated stainless-steel baffles attached to the pipe assembly. The burner can be placed in the outside airstream or in the outside / return mixed-air stream. But to prevent potentially hazardous combustion byproducts of indoor-air contaminants, the burner is placed in the outside airstream only. The required airflow across the burner must be within a specific velocity range (typically 2,500 to 3,500 fpm) for proper combustion. For variable airflow units, a modulating bypass damper or profile plate maintains the airflow velocity within the specified velocity range. Otherwise, the burner can experience inefficient operation, generate odors in the occupied spaces served, and create an un-safe increase in certain products of combustion.

Canada Blower Co. produces different types of gas-fired air makeup units for industrial building ventilation.

Gas-Fired Pressurization Units move large quantities of air at low temperature differentials (usually 50° or less), which is a strategy to minimize temperature stratification in the large spaces they are employed to heat. The equipment is typically mounted on the roof of the facility or at grade on elevated supports to ensure that the supply air is delivered high. The high air delivery allows for a longer “throw” of the air, thereby requiring less equipment to cover the required floor area. The most common fuel is natural gas, however, units can be converted to burn propane. There are two primary categories of gas-fired AHUs: indirect-fired and direct-fired.

Canada Blower Indirect-fired units burn the fuel and air mixture inside of a heat exchanger while the air traveling to the space passes over the outside of the heat exchanger. In this design, the products of combustion travel through a vent to the outside of the building.

Direct-fired units utilize air that will be sent to the heated space for combustion without use of a heat exchanger. The products of combustion are mixed directly with large volumes of outdoor air. Such mixing is considered safe because of the high dilution ratio.

Canada Blower Co. offers different types of Industrial Make-Up Air Systems for larger industrial plants ventilation needs.

Negative Air Pressure in industrial manufacturing facilities can create problems such as:

- Exhaust fans losing performance, as the building pressure becomes negative.

- Pilot light outages and exhaust system failure on natural draft gas equipment.

- Cold air drafts and infiltration of dirt and contamination from outside.

- Difficulty opening or closing exterior doors.

Nausea and headaches among personnel due to inadequate ventilation. In temperate climates or during mild weather, moderate amounts of make-up air can be supplied by simply opening windows or overhead doors. However, this is usually not the case in industrial and commercial facilities. Forced ventilation Make-up air is required.

Canada Blower Direct Gas-Fired Make-up Air Units supply tempered and filtered air to the indoor environment. In summer, a direct-fired unit may be used as an air handler, with the heater disabled. By adding a DX or evaporative cooling section to the unit, it may be used to supply conditioned air year round.

Make-Up Air Applications:

There are three general applications for Make-Up Air Units:

- Direct Compensating Ventilation

- General Area Ventilation

- Door Heating

Direct Compensating Ventilation.

Conditioned Air is Delivered to the Immediate Vicinity of Exhaust. This is the case for welding fume extractors, stovetop exhaust hoods, paint booths, or similar applications.

General Area Ventilation.
 
Conditioned Air Blankets Entire Area of Building to Compensate for Many Exhausts. Introduced in Cleanest Part of Building - Flows to Negative Pressure Areas - Picks up Dust, Vapors, and Odors en route.

Door Heaters

Heated Air is introduced at open doors to warm incoming air or compensate for loss. Heater may also be used as part of an “air door” system.

Typical Industrial Uses:

* Plating Tanks

* Paint Spray Booths

* Welding Operations

* Chemical Exhaust

* Degreasing

* Factory Ventilation

* Plastic Molding

* Foundry Works

* Grinding & Buffing Operations

Typical Commercial Uses:

* Warehouses

* Kitchens

* Entryways

* Gymnasiums

* Pools

* Exposition Buildings

* Garages

Make-Up Air Volume Requirements:

The recommended method for calculating Make-up Air Volume is to determine the total CFM capacity of exhaust fans, blowers, stacks, etc. in the building and add 10%. This will create a positive pressure in the building.

When information is not available, the following estimates may be used to determine approximate requirements:

- Paint / Spray Booth: 100 to 200 CFM per sq. ft. of face opening.

- Oven Exhaust: One air change per minute.

- Fume Exhaust: Area of Pipe (in square feet) x velocity (3,000 feet/min average) = CFM.

- Roof Ventilator: same as Fume Exhaust.

- Canopy Hoods: 100 to 300 CFM per square foot of hood open area.
 
- Furnace Combustion Air: Minimum CFM = BTU/hr rating / 6,000.

- Drying, Baking, Curing Ovens: 100 CFM per square foot of booth cross section.

- Pickling or Cleaning Tanks: 150 CFM per square foot of door opening or 200 CFM per square foot of hood face opening.

Canada Blower Direct Gas-Fired Air Heating System may be used in an industrial or commercial application for any or all of the following purposes:

. Make-Up Air Heating – Air is introduced to a building to replace air being exhausted.
. Space Heating – A unit provides primary or supplementary heating to a building space.
. Space Pressure Control – Building or Room Pressurization is held within a range.
