A BLESSING ON A HOT DAY.
A New Means OF Cooling and Freshen-
ing the Atmosphere.

Boston transcript
To cool the stuffy atmosphere Of a room
where human beings are gathered together
for hours at a time, and at the same time
to purify and freshen 1t, has long been a
study with ventilation experts, but what
is believed to be the first apparatus to ac-
complish this dual purpose successfully was
tested in a Milk-street office a few days
ago. There were eight persons present, In
Guiding an official of the National Shawmut
Bank and a representative of Thompson's
Spa. The room in which the test was made
had been closed for some time and heated
artiicially by means of three three-wick
oil stoves to a temperature of about 100 de-
grees. The air was noticeably impure.
All that could be seen as the witnesses
entered the room was an upright cylinder
about four feet tall, mounted so that its
base was about seven feet from the floor. A
few pipes and tubes extended to a small
pump, electric motor and ice tank under
test began at $40 p. m, the temperature at
the ceiling being 15 degrees and
at the breathing level 80. eight adults
by 1O1a feet. The inventor, Mr.. Fred
erick White, OF this city, then started the
pump and began the process of cooling and
regenerating the air in the room. No new
air was admitted, but readings taken every
five minutes showed as follows: At S:15
p. m, ceiling So degrees, breathing level 81,
g reduction of twenty degrees and ten de-
grees on the respective readings within the
first five minutes. At 800 p. m, ceiling rs.
breathing level a. At 3:25 p. m, ceiling rs,
DreaInlnR level "a DluS. AL 3.0U ID. M, ceiling
rs. breathing level ~. The air then felt clean
and cool, instead Of sultry and fetid, as at
first, and with the temperature thus rem
dered practically uniform the test ceased.
On being asked how the work was accom-
plished so readily Mr.. White said: The air
is cooled by bringing it into contact with
water. Every minute the apparatus dis
tributes Az gallons Of ice-cold water over
1900 square inches of cooling surface, and
the air is brought into direct contact with
this water. The apparatus is worked by

cubic feet of air per minute at a pressure of
about 80 pounds" 1t was noted while the
machine was in operation that the water
going into the cylinder was at Al degrees
temperature, while returning it was AZ de-
grees. The temperature of the water re-
turning to the ice tank was raised six de-
grees by the heat that was being extracted
from the atmosphere.
On June 2 a test was made in which the
machine was pitted against the Oil stoves
to see which would have the most effect on
the condition of three connecting rooms.
At 11:15 a. m. the thermometers registered
as follows: In Room 2G7. IS degrees; in
Room EOS; Sc degrees; in Room 2O9, 6S de-
grees. The thermometer at the ceiling in
Room 2GS in which the Regeneration was
operated registered 81. Two three-wick
burner oil stoves were lighted at the time
the machine was started. The Regeneration
was started and ran continuously for half
an hour. At the end of that time all the
thermometers registered exactly the same
as at the start. with the exception of the
Thermometer at the ceiling in Room 2Os,
which registered II degrees at the end OF
thirty minutes. During the entire time both
oil stoves were burning, and there were five
people in the offices. 1t is estimated by ex-
perts that each oil stove is equivalent to
the presence of thirty-hve persons.
By regulating the speed of the motor any
desired degree Of GOODNESS can be created
and maintained.
A company known as the Regenerated
Cold Air Company has been formed, with
Offices at 17 Milk street, to develop this
useful invention. Prominent professional
and business men of character and ability
are interested, and their confidence in the
invention has already been justified by the
many inquiries being constantly received by
them from all over this and foreign coun-
tries; and by orders that have been re-
ceived for the installation of plants they
believe the Regenerators will unquestion-
ably accomplish a threefold purpose-in
any excess of humidity from It; in winter
atmosphere that is abnorInally dry; in both
summer and winter TO cleanse and purify
the atmosphere. 1t is attracting the atten-
ton of proprietors of banks, theaters, res
taurants, hospitals and offices. In such
places ice water is used as the cooling
agent. For cold storage and refrigeration
the device will serve the purpose by en-
ploying cold brine. Medicated water en-
ables the operator to disinfect the air of a
room where this is desired, and the ma
chine will not only reduce the temperature
of a room, but may bS easily adjusted TO
maintain a definite temperature automat-
ically. The commercial advantages of this
feature are self-evident.
