Improvements in the Refrigeration of Chambers or Stores.
I, ROBERT CHARLES ALBERT BANFIELD Mechanical Engineer, of St. Clère,
Walwood Road, Leytonstone, Essex, do hereby declare the nature of this invention
to be as follows:-
This invention relates to means of cooling air supplied to or circulating through
chambers cabins or stores by contact with extended surfaces cooled by refrigerated
brine or other uncongealable liquid. For this purpose, the cold liquid is by pumping
or otherwise caused to circulate from and to the refrigerating apparatus and through
a trough or a set of troughs, which are preferably kept on the same level with the
cells or tanks of the refrigerating apparatus so as to economise power in effecting the
circulation. On the trough or on each of these are mounted several transverse shafts
which are caused to revolve. On each shaft there are fixed a number of parallel discs,
and the shafts are at such a level relatively to the liquid in the trough that the discs
are partly immersed in the liquid. The trough or set of troughs is situated in a
channel or passage through which the air passes in a current created by a fan or
otherwise, the direction of the current being parallel to the revolving discs. Thus, as
the discs revolve in the refrigerated liquid, the air passing in numerous streams
through the spaces between the discs becomes cooled, depositing excess of moisture
and impure gases or other matters that may be suspended in it, by contact with the
cold moist surfaces of the discs. The air having the amount of its moisture thus
reduced to that which is due to the reduced temperature, becomes capable of absorbing
fresh moisture in the chamber or store where the temperature is higher.

Improvements in the Refrigeration of Chambers or Stores.
I, ROBERT CHARLES ALBERT BANFIELD Mechanical Engineer of St. Clére, Walwood
Road Leytonstone, Essex, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
This invention relates to means of cooling air supplied to or circulating through
chambers cabins or stores by contact with extended surfaces cooled by refrigerated
brine or other uncongealable liquid. For this purpose, the cold liquid is by pumping
or otherwise caused to circulate from and to the refrigerating apparatus and through
a trough or a set of troughs, which are preferably kept on the same level with the

the circulation. In the trough or in each of these, are mounted several transverse
shafts which are caused to revolve. On each shaft there are fixed a number of
parallel discs, and the shafts are at such a level relatively to the liquid in the
trough that the discs are partly immersed in the liquid. The trough or set of
troughs is situated in a channel or passage through which the air passes in a

pended in it, by contact with the cold moist surfaces of the discs. The air having
the amount of its moisture thus reduced to that which is due to the reduced
temperature, becomes capable of absorbing fresh moisture in the chamber or store
where the temperature is higher.
Fig. 1 of the accompanying drawings is a longitudinal section and Fig. 2 is a
plan of apparatus according to this invention. A indicates the reservoir of brine
or other uncongealable liquid cooled by any known refrigerating apparatus, B is a
rotary, or it might be another, pump by which the cold liquid is drawn from the
lower part of A and transmitted by a pipe C to the tank D, whence it flows back to A
by the pipe E.
The tank D has on its sides bearings for a number of transverse revolving shafts F
each carrying a number of parallel discs at small intervals apart; which are partly
immersed in the cold liquid in the tank D.
The air to be cooled, propelled by a fan or ventilator G or otherwise, passes along
the upper part of the tank D, and through the spaces between the discs being thus
divided into a number of thin parallel streams exposed on both their sides to the
action of the cold moistened discs.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The herein described method of cooling air by causing it to pass in numerous
thin streams between discs revolving partly immersed in cold liquid.
2. For the purpose of cooling air in the manner above referred to, apparatus
consisting of a number of parallel discs mounted in the air channel and caused to
revolve partly immersed in cold liquid, circulating from and to refrigerating apparatus,
substantially as described.
