The advantages of mechanical
Overice refrigeration are numerous
and very great. and cover cost as
we'll as results achleveu. No one
who has tried mechanical rcfrigera-
tisn can ever be induced to return
to the use of ice tor refrigerdting
purposes. The reduction in the
cost, as compared with the old
method, is a very large item. II
varies, Of course, as tho size of the
machine used is greater or less,
the cost being relatively greater
as the size of the Ieirigeraling ma
chine decreases, but with a 30 ton
refrigerating machine, run to its
full capacity, the saving in the
cost of refrigerating a given space,
rs compared with ice refrigeration,
is about in the ratio OF five to eight,
while some results are as low as
one to two, and many run the year
round at about three 10 five. Even
with the brine system the refriger-
ating power can be successfully
Transmitted for several squares,
and with the ammonia system dis
tance does not affrct the refrigera-
ting power, 1t being just IS effect
i've ah agent at a mile from the
central plant ss within ten feet
from the alnmOnia receiver.
In New York city seven firms of
slaughtera formed company and
put in a so ton refrigerating ma
chine, using brine as the agent.
The Arms are, in some Instances,
Two squares from the plant. This
machine cools Is chill-Iooms with
a capacity Of 400 carcasses Of beet
per day, besides several temporary
cold-storage rooms, aud the ex-
pense of the entire plant is but go
per cent Of what the seven hrns
formerly paid for ice. This does
not include the cost of haudling
the ice, which was, in itself, very
considerable item,
la ST. Louis, NO., and Denver,
COL, q system OF refrigeration is
in operation which is as convenient
to consumers as the use of gas for
Illuminating purposes. The sys
tenn WAS first introduced in Den
ver; the parent company being
located in st. Louis, where, after
success had been achieved -in
Denver, the system was started
and ID being annually extended.
The system is very simple one.
A small line Of pipe for conveying
liquid anhydrous ammonia, and a
larger ons for returning the gas
after it has been used ara laid in
conduits to any desired point. Al
any point where refrigeration is re
quired . small tap-pipe is intro.
iuced into the feed-pipe contain,
ing the liquid ammonia, and is con.
nected with a coil of pipe il
the refrigerator or co0ling-rOOm
By turning valve a small STREAM
Of ammonia il drawn into the re
frigeratingc0il, where it immediate
1y expands and takes up the heat
the degree OF cold can be regulat
ed by the flow of ammonia, a largi
stream being admitted at first
antil the desired temperature hal
I,een attained, when the flow cal
