DIRECT AND INDIRECT GAS FIRED AIR HANDLING UNITS


Canada 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.

Canadian Blower Co. has developed a few methods of effective building ventilation and cooling. 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. In other circumstances, the attentiveness of an audience or student group may be a factor that spells success or failure for the project.

To obtain a reasonable degree of personnel comfort in hot weather, there are three basic factors that should be provided for in the ventilation and cooling system of a commercial or industrial building.
         
REMOVAL OF EXCESSIVELY HOT AIR
 
The first step toward controlling the hot air problem is to provide for the removal of excessively hot air from the building. This superheated air frequently mixes with the air in the cooler areas of the building to produce an overall temperature increase. As superheated air is frequently localized around heat-producing machinery, it should be exhausted from the building near its source.
 
SUPPLY COOLER AIR
 
As a rule, outside air temperatures are considerably cooler than those inside a building. As superheated air is exhausted, provision should be made to replace it with fresh, cooler, outside air. When high temperature air is replaced by outside air, a substantial improvement in the average air temperature of the building results. Even where outside air temperature may be in the 80s or 90s, invariably it is 15 degrees to 20 degrees cooler than the air it replaces. This is a very important improvement to the individuals affected.
 
VENTILATION
 
A very effective way to overcome the discomfort of a hot, stuffy room is to create a breeze. The circulation of air over a person's body immediately causes a cooling effect on the skin. When air is passed over a moist surface, it will evaporate some of the moisture and thus lower the temperature of the surface. This is precisely what occurs when air circulates across the human body. By creating a gentle breeze throughout a room or area, a great deal of cooling comfort is provided for individuals who must work there. This pattern of air circulation is sometimes called "breeze conditioning".
 
Commonly available practical methods of plants cooling are:
 
* Exhaust fans or Power Roof Ventilators (PRVs).
 
  To do a satisfactory job of eliminating excessively hot air, it is usually essential to have powered wall and/or roof exhausters. These fans should also help to control air pressure within the building whether it be negative or positive pressure.
 
* Supply Fans or PRVs.
 
  A large number of buildings use exhaust PRVs to exhaust fumes, smoke, dust or other contaminants unavoidable in the operation of the business. As a result, these buildings are frequently under a severe negative pressure. The solution to the problem of this kind is usually found in the use of supply fans or "make-up" air ventilators.
 
* Air Circulators.
 
If the exhaust and supply air requirements of a building have been carefully engineered and installed, and there continues to be a high instance of worker discomfort, the problem usually relates to the matter of air circulation. In this way, in addition to maximum benefit from the fresh, cooler air, occupants receive the added comfort of air circulation over their bodies and they are not adversely affected by the superheated air being exhausted from the building.
