If relatively straightforward breeze conditioning system is possible,
the rate of air velocity method outlined above should be the basic
method used. However, there may be rooms or areas within the building
that will require special treatment. If so, one of the other methods,
such as spot cooling or zone cooling, may be combined with the basic
method to achieve the over-all objectives.
Air circulators may be effectively used to boost air velocity through
large buildings that have a flow pattern difficult to control. Air
circulators are also used to redirect air into occupied areas near
floor level. Air circulators are also effectively used in locations
where adequate exhaust and supply air fans may be lacking. Air
circulation alone may provide heat relief and cooling comfort to
individuals in the area. Canada Blower's Type CABL fan is ideally
suited to this application. For many installations, fans like this may
be positioned 8' to 10' above the floor and at approximately 50'
intervals to obtain a continuously circulating column of air across a
room or building. To broaden the column of air, fans should be located
abreast of each other 15' to 20' apart. Fan locations and positions are
easily adjusted to the requirements of the area.
Although an accurate, intelligent calculation of the required air
volume for a breeze conditioning system has been made, there are
practical limitations in most buildings that may seriously affect the
final results. By giving these limitations proper consideration in the
planning stage, the system can usually be modified to compensate for
them. Some of the more common limitations are listed here.
It is obvious that interior partitions restrict and interrupt the flow
of air through a structure. The effect of these partitions on the
system must be analyzed and solutions found. In buildings with very
high ceilings. the cross-sectional area factor may become unrealistic
in calculating the required air volume. In most instances, inexpensive
baffles can be installed across the building width to reduce the
effective cross-section to an area 10' or 12' above floor level.
Machinery, raw materials and finished goods that obstruct air
circulation. These obstacles, like interior partitions, must be
considered and methods worked out to overcome the problems they create
to the proper circulation of air through the structure. Frequently, the
location of heat-producing machinery will seriously interfere with the
preferred pattern of air circulation. This situation can destroy the
effectiveness of the system. An alternative plan to overcome the
problem is essential.
Another limitation of the very high ceiling or roof is the difficulty
of maintaining the air velocity near floor level. The baffle method
just described is usually the best way to reconcentrate the air flow
along the floor level where it will be effective in providing personnel
comfort. In large buildings, baffles may be required at l00-foot
intervals to keep air flow near the floor level.
Operations within the area frequently require wall openings or loading
doors that will drastically interfere with the desired airflow pattern.
In some cases, individuals may open windows that should remain closed
to maintain effective air circulation. A remedy for each of these
problems is required. For maximum efficiency and economy, a good layout
will avoid the restricted intake opening. The type of exhaust equipment
normally utilized is most economical and efficient if static pressure
in the system is 1/8" or less. To obtain this condition, air velocity
through intake openings should not exceed 1,000 feet per minute, a
lower figure is usually desirable.
