The Heating Plant.
One Of the most important features
Of the building is the up-to- Their minute
system of heating and ventilation in
stalled by H. Kelly & Co., of this
city. All the air that enters the build
ing, summer or winter, is thoroly
washed and purified, and any tempera-
ture that is desired can be maintained
indefinitely, and II. Kelly & Co. have
obtained conditions which approach
ventilat1ng appliances. The fresh air
is taken in thru a shaft at a point
about twenty feet above the roof and
carried direct to the fresh air chamber
In the basement From this chamber
the air is drawn thru coils Of one
inch pipe, the purpose of these coils
being to temper the air whenever the
outside temperature falls below 40 de-
grees. This is accomplished in a very
simple manner by means of thermo-
stat which opens automatically the
controlling valves to the temper1ng
coils turning steam, on to one or more
| of the coils, according to the tempera-
ture Of the incoming air.
! The next step of the airs progress
1
need of the tempering coils, as the air
is now treated to a shower bath, which
| would not unnaturally freeze up were
air brought to it registering below the
freezing point. The purpose of this
spray is to remove the smoke and
other impurities from the air and the
amount Of foreign matter taken from
! the large catch basin beneath air
washer is evidence Of its efficiency.
Next in the course of the air cur
| rent is series of battle plates, made
of heavy copper and set at sharp
4 angles the plates being staggered so
as to offer the greatest impeachment to
the passage of the moisture-laden air,
and, by the force of the impact, to
whip" the moisture out Of it.
The action of these BATTLE plates
srobs the air of it's surcharge of mois-
i ture and introduces it into the sys-
tenn at about the normal degree OF
! humidity. The effect of this is partic-
ularly noticeable in summer time; by
lowering the temperature only few
degrees and reducing the humidity to
! a considerable extent, it is possible to
give the occupants of the building the
sensation Of a marked drop in temper
allure on entering from the hot and
dusty atmosphere of the streets.
The fan, or blower which furnishes
the motive power to move the great
| QuanIlLy OIL air Ie4uIeu Liz u ~ IIiS
system is of a special type built ex-
pressly for this building. It has
capacity for moving 42,089 cubic feet
of air per minute.
! In summer the system supplies
washed air at lowered temperature
and free of surplus moisture.
In the main ducts are hampers
which control the velocity OF the air
current, the range being from
| 400 feet per minute in the
offices and retiring-.rooms to
l1,400 feet per minute In the
/ main banking-room, where the loca-
ton of the registers Is favorable to the
movement of a large body Of air
without perceptible draft The inlet
registers here are located on the walls
we'll above the heads of the occupants.
and the exhaust registers are in the
baseboards of the bank furniture.
There is no question but that this is
one of the best heated and ventilated
buildings in the country today.
