URGES ARTIFICIAL COOLING.
DIR. DOREAIUs SAYS LIQUEFIED AMMONIA
WOULD MAKE ALL BUILDINGS COM
PORTABLE IN SUMNER

DR. R Ogden DoreInus said this yesterday as he
sat in his laboratory working big palm fan and
wishing that the old buildings Of the College OF the
City of New-York had some system OF artificial
cooling. He has been experimenting in processes
OF this kind for many years. and has made mum
Der OF valuable discoveries In the use of hqueded
ammonia. He SAYS that rooms of all sorts could be
cooled TO a comfortable degree at One-tenth the
cost Of heating them in winter. and he cannot IN
derstand why some OF the new buildings do not in
troduce the system
I desire 10 awaken the attention OF the public
10 methods o. artificial cooling which have been
In use in the United States for thirty years. con-
tlnued DR. Doremus Large brewerles and abat-
toirs in NeW-YOrk, Chicago and other large cities
in this country ana in Europe employ hguefed
ammonia for cooling purposes in place of ice Am
monia g4s hquefes AT 6'9 atmospheres. and for
this reason is preferable TO Lquefed carbonic gas
which requires 81 atmospheres, or TO liquid air, at
30 atmospheres For the purpose .of cooling build
ings iron pipes decorated in accordance with the
walls and color scheme, should be run through the
rooms near the ceiling one end Of the pipe would
he connected with a cylinder Of Hquehed ammonia
from which, on opening a stop cock, the ammonia
would be released pass through the pipes and cool
them. II would be delivered from the other end
OF the pipes into another cylinder partly nled with
water and would instantly be absorbed one cubic
inch Of water Will absorb +s0 cubic inches of am
rnonia gas. BY heating the water in which the am
nonia has been absorbed the ammoniac gas viii
be discharged. and may be reHquehed In this
way II can be used over and over again,
