DIRECT AND INDIRECT GAS FIRED AIR HANDLING UNITS


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

DIRECT GAS FIRED AHU Airhandler


A direct gas-fired AHU airhandler 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 Airhandler


An indirect gas-fired AHU airhandler has a sealed combustion air 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 recirculation air applications.


AHU AIRHANDLER COMPONENTS


Though simple in principle of operation, direct gas-fired air-handling units AHUs have sophisticated burner-control systems. Unit fan 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, air supply fans and blowers, outside air intake air hoods, intake air dampers, ventilation filters and blower burners.


AHU HOUSINGS


AHU fan 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) ventilators with forward-curved or backward-inclined fan wheel 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 AIR 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 air 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 air-handler dampers are most standard. The fan discharge is located at the opposite to isolation-damper position.


AIR 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 blower 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 air handling units, a modulating bypass damper or profile plate maintains the airflow velocity of the airhandler within the specified velocity range. Otherwise, the burner blower 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. has introduced a new reliable and efficient air make-up unit designs for industrial building ventilation. In industrial plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees.

Direct Gas-Fired Air Heating Systems are a class of equipment utilized primarily in industrial and commercial environments to provide for worker comfort. To a lesser extent, these systems are used to condition air for process and finishing applications such as material drying and paint curing.

These systems have gained widespread use due to the fact that they are inexpensive to build, maintain, and operate compared to other furnace types of comparable heating capacity.

The feature that differentiates a Direct Gas-Fired Heating System from other types of heating equipment is its burner system. A “trough” or “line” burner is installed directly in the supply air stream. Combustion products are introduced into the building space during operation.

The key advantages are simplicity and efficiency. No heat exchanger is required. This eliminates component installation and maintenance costs. With no heat transfer losses, the unit is nearly 100% efficient.

The primary disadvantage is the introduction of waste products into the airstream. For this reason, both ANSI Z83.4/CSA3.7 and ANSI Z83.18 standards state: “Heaters covered by this standard are intended for use in industrial and commercial pplications.”

ANSI Z83.18 states further that: “Heaters covered by this standard are not intended for use in any area containing sleeping quarters." Carbon Monoxide and Nitrogen Dioxide are the primary pollutants. These are limited to no more than 5.0 PPM for CO and

0.5 PPM NOX, a fraction of OSHA allowable Permissible Exposure Limits(PEL).

Negative Air Pressure inside industrial facility 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

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.

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.
