Humans are warm blooded animals whose normal body temperature is 98.6°
Fahrenheit. However nike huarache kaufen , we
are most fortable when the air temperature around us is in the 72°-to-78° range.
If there is air motion around us, the effect of "wind chill", or evaporative
cooling, enables us to feel fortable in a much higher air temperature. As the
natural air temperature in most non-air conditioned buildings is much warmer
than outside air temperatures, the problem of keeping humans fortable is
primarily a cooling problem. Of course, this is not the case in periods of very
cold weather. Our purpose is to discuss the environmental problems that
frequently exist in periods of moderate to hot weather. An effective, economical
solution of these problems is vital to the suess of any business. Humans are

frequently exist in periods of moderate to hot weather. An effective, economical
solution of these problems is vital to the suess of any business. Almost any
individual who finds himself in a situation or location that produces a feeling
of disfort quickly seeks relief from the problem. If there is no convenient
solution to his disfort, he may react in a number of ways. Invariably, the
disfort and his reaction to it has an adverse effect on his attitude, behavior
and general efficiency in his job or responsibility. In almost any building or
room used for mercial and industrial operations, it is quite likely that there
are recurrent conditions that cause personnel disfort. This is particularly true
unless an expensive system for the circulation of refrigerated air (air
conditioning) has been provided. In mild to hot weather, the disfort of
individuals is generally due to the build-up of intense heat within the
structure. This bees a severe problem in summer because the sun load on the
building is added to the normal sources of heat build-up within the building.
Most buildings have sufficient ventilation to remove smoke and fumes detrimental
to health. However, it is unlikely that that system contributes very much toward
the fort of the individuals who oupy the mom or building. If an individual is to
produce maximum results, he must be allowed to function in an environment as
nearly ideal as can be provided. In fact, the benefits in terms of efficiency
and productivity can be substantial. Failure to provide a fortable environment
can be very expensive in terms of errors, work slow-down, plaints nike
free 5.0 v2 für damen , absenteeism, etc. If the major factor is a
hot, humid atmosphere, which may include smoke, dust, fumes or other irritants,
a practical and effective approach to the problem is available. To obtain a
reasonable degree of personnel fort in hot weather, there are three basic
factors that should be provided for in the ventilation and cooling system of a
mercial or industrial building. When the air temperature in the oupied area of a
room or building exceeds 78° to 82°; most individuals begin to feel unfortably
warm. The first step toward controlling the problem is to provide for the
removal of excessively hot air from the building. This superheated air
frequently mixes with the air in 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. This will prevent some undesirable air temperature increase in other
areas. 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 nike

building may have a temperature of 125° to 150°. This is usually the case where
heat-producing machinery is in use. Similar air temperatures frequently our near
the roof or ceiling where rising warm air is trapped and further heated by the
sun load on the roof. When this 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° to 20° cooler than the air it replaces. This is a very important
improvement to the individuals affected. A very effective way to overe the
disfort of a hot, stuffy room is to create a breeze. Before refrigerated air
systems were invented, mechanical fans of every description were used to provide
air circulation. 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 ours when air circulates across the human body. By
creating a gentle breeze throughout a room or area, a great deal of cooling fort
is provided for individuals who must work there. This pattern of air circulation
is called "breeze conditioning" by Buffalo Fan engineers. It is effective even
when the air temperature may be 85°' to 95°.
