THE COLD STORAGE HOUSE.

In Construction.


want to build a cold-storage house
for my family and farm use. and should
like instructions. particularly with re-
gard to ventilation and insulation. /
especially would like to know how
large storage room / can cool to the
proper temperature with a given
amount of ice in the building. Also
what is the best temperature at which
to keep the cold storage room for milk
preservation and fer general domestic
imposes? NJ. G.
A cold-storage house should be built
with the same care, and on the same
methods, as an ice-house; as to keep
cold in a house required the same meth
DDS as to keep heat out. The walls
should be non-condncting, and while
the ice is not kept in the house, but in
receptacle above it. made like an ice
house, yet to retain the GOODNESS of the
Ice above the cold chamber the mode
of constructing this must be the same
as for an ice-house.
1t goes without saying that ventila-
tion is wholly fatal to the maintenance
of lower temperature than that out
side the building. The object is to re-
tain temperature as near the freezing
point as possible, and yet not to per-
init freezing. Any method of ventila-
ton viii necessarily be fatal to this.
SO that as the purpose of ventilation is
to preserve the purity of the air in the
cooler, and this may be done by other
ncans,r these must be taken; and en-
trance of air from the outside is be
avoided
As the impurities that win gather in
cool chamber will consist of moisture
derived from the coatents OF the cold
closet, any method of condensing this
and gathering it will be equivalent to
the effects OF ordinary ventilation,
as it will purify the air by talk
ing from it these impurities with
the moisture of it. This is uone
most effectively by the use of fresh
stone lime, which absorbs one-third its
weight OF waterNfroln the air about it,
and as dry air is pure and free from all
matter that may be suspended in it be-
core it is dried, the purlty of the closet
is secured by this use OF lime. A sup
ply of the fresh lime is therefore all
that is needed for this PURPOSE As it
becomes saturated with moisture it
falls to dry powder which is the hy-
drate OF lime, and is then replaced by
fresh supply The lime may be kept
in II pan in the house.
The ice is used in this way: Above
the cold closet there is II receptacle for
the ice, protected in the same way as
the icc-house is-that is, by double
walls and double door through which
the ice is put into it. The iloorsof this
ice chamber is OF metal as the best
conductor; galvanized iron or sheet
zinz is the best material, and this
is SO disposed that the wa
ter from the melting ice will flow to
one corner, where drain pipe is fitted,
having safety against entrance of
air--a curved trap made like an $ laid
on its side. 1t will be an extra means
Of safety to have two OF these, one in
the closet, through the corner of which
the drainage flows, and another ont
side at the entrance into the drain
through which the waste water es-
capped.
1t is impossible to say just how much
ice will be required to supply any sort
OF cold-storage closet. 1t depends upon
the mode in which it is constructed, on
the size OF it, and on the quantity OF
