AIR COOLING APPARATUS.

Our fellow-citizen, Mr.. e. Fixary, has invented
new process by which the mercury can be
brought down to 20 or rs degrees centigrade be-
low zero during the time taken to bring 1t down
to zero by any other process, and ss the temper
ature Tor the preservation OF vegetable or animal
| substances must only reach four or Eve degrees
above zero centigrade, that degree will be OBJ
tanned in less time. with less fuel and labor.
The principal object Of this invention Is the
cooling Of air in buildings, cellars, breweries.
ships. cars, meat packing establi shments, etc.,
for the preservation of matter in general It
is composed Of series Of pipes, either In form
of tables or coils, in which crculates refriger-
ating body; these plates or coils are surrounded
by radiating cylinder open at both ends. and In
combination with an heicoid fan f1rcing the air
rotatorly against the refrigeratng surfaces con-
tanned in the cylinder or exterior envelope which
is placed inside OF an apartment.
It lie we'll known that to effect rapid cooling
OF the air 1t ia necessary to agtate in the int
rior OF the apartment subj scted to cooling
process and also that in using pipes for the CIR
cuation OF reftigerating bodies the vapors OF
water, held In suspension by the air, will con.
dense on the refrgerating surfaces and form n
coat of snow, which, increasing ia thickness,
limits the cooling OF the air to few degrees bs-
low the freezing point, creating at the same
time damp atmosphere, though after long
operation. This invention s based upon the
well known principle that lee being a very
slow conductor OF more active refrig Grating
agent, 1t is Indispensable TO prevent the forms
tion OF snow or ice upon the pipes in which the
refrigerati0g agent circulates Ia order to obtuin
very low temperature OF dry air and for thls
purpose the shaft by which the heicnid fan ia
made to revolve Is armed with brushes or
scrapers. so as 10 cauee the snow to be swept off
as soon as it is formed on the pipes.
Htor af.sr Is...l-
centre OF an apartment and 80 disposed that the
cold air is distributed equally all around 80 as to
displaoe the warmer air and push it in the drec-
ton OF the fan that forces 1t again and again
against the retrigerating PLACES, which plates,
being constantly freed OF snow, produce an in
tense and continued cold.
THIS invention may be adapted with great ad.
vantage in brewerles and other industrial estab-
lishments where vegetable matters are in fer.
menta ion; in such csses these matters will dis.
engage gases, which will forcibly condense and
form into snow upon the pipes, and the snow
being removed will leave a dry and pure cold
ar 10 the apartment. 1t may be used for the
storing oil ma 4ufactured ice, with saving of at
least 70 per cent, and also for it's preservation in
its concealed state. For this series of pipes
placed under the ceiling where the warm air
always ascends should be provided with scra-
pers or brushes, made to be moved by
snow formed on the pipes and make
1t fall upon the layers OF ice ia order to cover il
and fill up the interstices between the blocks. 40
as to make solid body through which the air
cannot circulate. The cryst cation OF the water
not being the same as that of the vapors of water,
the solid ice can be separated by layers as it is
when stored.
The ordinary way of storing manufactured ice
offers many Inconvenience: first, the m ltine OF
the ice caused by the immediate application OF the |
sawdust, which is ct higher temperature than |
the ice ITSELF second, the incrustation OF the saw
dust into the ice, which gives it a bad appear.
ance and causes great loss before it is removed:
and then the bad taste it gives to the ice ii |
porous. All these Inconvenience can be avoided |
by using the process above mentioned, which, in |
this case, may be termed SNOW AND. COLD AIR |
