This Distribution OF. Refrigeration In
Cities from Central Stations.
The distribution of refrigeration from
central stations through pipe lines is dis
cussed by John f. Starr in the Engineer
ing Magazine. Some of the purposes to
which this system is applicable are thus
mentioned
The principal hotels and restaurants
and downtown butcher shops III St. Louis
and Denver are using this system In their
storage boxes. But the applications OF
the system do not end here. In many
hotels. cafes and saloons. ice IL required
for water pitchers and to crack up for
mixing beverages. In such cases a min
iature brine tank Is provided, through
which the expansion coils connecting with
the pipeline are run. Mods OF suitable
size are placed in the brine, and the oper-
alton of ice-making is carried on just as
at the large ice factory. Where small
amounts Of ice are needed for cracking
up, a small insulated reservoir is pro.
vided and the expansion pipes are placed
close to the sides. Water Is then poured
into the reservoir, and ice forms on the
expansion coils and extends towards the
centre of the reservoir until a solid mass
is frozen. This is Clipped out as desired,
and new water added from time to time.
Another important branch Of the bust
ness Is supplying cold water for large
stores. factories and offices. The install
lation for this service consists of a water
tight insulated tank, having at the
bottom a coil through which the hydrant
taps. About a foot of water is
and Just underneath the surface OF
this water. the expansion pipes are
placed. A sheet of ice five or six inches
thick is formed by the action of Enc ex-
pansion coil. thus Keeping the water coils
constantly surrounded with ice-warer Of
low temperature. The city water so
cooled may be then carried by insulated
piping to taps in any portion of the build
ing. Some large installations Of This kind
are in successful operation. The cooling
of soda-water fountains Is effected In the
same way. The manufacture OF ice-cream
is also more easily accomplished by the
aid of this system. Other branches of
business are also supplied. as the manu-
facture of perfumes and chocolate confec-
tions,
Among the Injuries furnished by this
system may be mentioned the cooling OF
livipg-rooms, which, in such O climate as
that of st. Louis. proves q great luxury.
The refrigerating company there started
in with contracts to reduce the tempera-
luI6 VA Cdlc6 Gud 0iAIuS-tOOAA WChuJ w
grees below the outside temperature. NO
difficulty was found in cheaply reducing
the temperature ever TO q lower
point han this, but sanitary consfdera-
tions, and the comfort of the f~requenters
of such places, determined that q differ
ence of from ten to fifteen degrees be-
tween the inside and the outside tempera-
ture was the most satisfactory. 1t Is
interesting to note that the same piping
used for the ammonia cooling service in
the summer is used for steamheating
purposes in the winter. It happens that
in neither Denver nor st. Louis do the pipe
lines reach any of the hospitals, though
the benefit of their use In such institu-
tons is apparent.
Figures are given to show that this SER
vice is less costly thar the shipping of
ice. and that it can be operated pro1tably
in towns having 5000 or more inhabiI-
ants,
