do hereby declare the nature of this invention to be as follows:-
This invention has reference to the cooling of air for use in refrigerating
chambers, and has for its object, principally, to provide a simple and inexpensive
arrangement or apparatus in connection with refrigerative machinery, by which
this cooling is performed.
According to this invention the apparatus or arrangement consists of a
plurality of suitable textile sheets disposed in parallel, and closely together,
through the spaces between which the air to be cooled is passed, say by a fan al
one end of the chamber in which they are contained; a series of pipes above,
through which cold liquor, said cold brine, which has been artificially cooled by
the machinery connected with the plant, passes, and from which it is distributed
on to the upper part of the textile sheets so that it-the liquor will flow down
these sheets a tank below into the open upper surface of which the liquid
flowing down the sheets falls; and a pump through which the cooling liquor
is drawn from this tank and forced into and through the pipes above.
In one construction, at the upper part a series of parallel tubes are provided,
leading from a crosshead or pipe, to which the cold fluid is pumped, and these
parallel pipes have each a slit or opening along their upper side. The textile
sheets are supported from these pipes, being passed over and resting on their
upper sides, and hanging down on either side; while their lower edges may dip
into the brine in the tank below. Then within this tank the pipes for cooling
the brine, and through which expanded ammonia, or other cold fluid is passed
or circulated, are disposed.
In some cases, the upper pipes may have a common connecting pipe at the
opposite end, similar to the distributing end.
In action, the whole of the brine or liquid pumped from the tank below, is
distributed by the header or cross pipe, and flows through all the parallel pipes;
and thence through the slots or openings in them into or through the textile
sheet material hanging over them. The liquor then flows down the sheets on
either side to the tank below.
The air to be cooled is introduced, say by a fan, at one end of the group or
chamber of sheets, and passes through the narrow spaces between these sheets
over the wetted cold surfaces to the réfrigerating chamber or space.

Improvements in Apparatus for Cooling Air for Refrigeration.
We, MONKS, HALL & COMPANY, LIMITED, of Warrington, in the County of
Lancaster, Manufacturers, THE COALBROOKDALE COMPANY, LIMITED, of Coalbrook-
dale, in the County of Salop, Engineers, trading together as The Liverpool
Refrigeration Company, of 24, Chapel Street, Liverpool, in the County of Lan-
caster, Refrigerating Machinery Manufacturers, and WALTER HENRY WEBB, of
North Cliff, Egremont, in the County of Chester, Manager for the said Company,
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 has reference to the cooling of air for use in refrigerating
chambers, and has for its object, principally, to provide a simple and inexpensive
arrangement or apparatus in connection with refrigerative machinery, by which
this cooling is performed.
According to this invention the apparatus or arrangement consists of a
plurality of suitable textile sheets disposed in parallel, and closely together,
through the spaces between which the air to be cooled is passed, say by a fan at
one end of the chamber in which they are contained; a series of pipes above,.
through which cold liquor, say cold brine, which has been artificially cooled by
the machinery connected with the plant, passes, and from which it is distributed
on to the upper part of the textile sheets so that it-the liquor will flow down
these sheets; a tank below into the open upper surface of which the liquid
flowing down the sheets falls; and a pump through which the cooling liquor
is drawn from this tank and forced into and through the pipes above.
In one construction, at the upper part a series of parallel tubes are provided,
leading from a header or pipe, to which the cold fluid is pumped, and these
parallel pipes have each a slit or openings along them." The textile
sheets are supported from these pipes, being passed over and resting on their
upper sides, and hanging down on either side; while their lower edges may dip
into the brine in the tank below. Then within this tank the pipes for cooling
the brine, and through which expanded ammonia, or other cold fluid is passed
or circulated, are disposed.
In some cases, the upper pipes may have a common connecting pipe at the
opposite end, similar to the distributing end.
In action, the whole of the brine or liquid pumped from the tank below, is
distributed by the header or cross pipe, and flows through all the parallel pipes;
and thence through the slots or openings in them into or through the textile
sheet material hanging over them. The liquor then flows down the sheets on
either side to the tank below.
The air to be cooled is introduced, say by a fan, at one end of the group or
chamber of sheets, and passes through the narrow spaces between these sheets
over the wetted cold surfaces to the refrigerating chamber or space.
The invention is illustrated in the annexed drawings which shew an apparatus
having the parts and characteristics described.
The drawings consist of a longitudinal section of the apparatus in Figure 1;
a cross section in Figure 2; and a detail in Figure 3.
€ repre-
Referring now to the drawings, a is the tank containing the cooling liquor,
with the cooling pipes 6 within it; and are the textile parallel sheets above
this tank. is the fan which forces air to be cooled over the sheets c.
sents the side and end walls, constituting the chamber in which the parts re-
ferred to are contained. fare pipes, extending longitudinally along the upper
part of this chamber, which distribute the cold liquor to the sheets c; and g

page_text: is a pipe at one end of the chamber, to which the ends of the pipe f are secured,
and which supplies and distributes the cooling fluid to them. h is a pump, say
of the rotary kind, having its inlet connected by the pipe h', with the lower
part of the tank ; and is a pipe connecting the discharge passage of the
pump with the distributing pipe or header g. The canvas or other textile sheets c
(the material of which is preferably of an open or soft nature; that is not hard
canvas) are made in endless form, and are supported by hanging or suspending.
them over the tubes f, while their lower ends are held by placing a solid rod i
in the lower portion of cach, as shewn in Figure 3, which act as weights. These
bars keep the sheets apart and stretched; and at the same time allow of expan-
sion and contraction.
The upper tubes f are provided with holes or slots f, through which the cool-
ing liquid is discharged onto the interior surfaces of the textile sheets c. A suit-
able size of tube f is about 2" diameter; and the bars i may be somewhat smaller,
say about an inch and a half.
The brine or other cooling liquid in (which is made cold by the introduction
of cold fluid into the pipes 6) is agitated by providing a partition at along the
centre, and a propeller at one end. This propeller works in an aperture in a
diaphragm, and forces the liquor along one side of the tank to the end, thence
through the partition by means of the aperture a² to the other side, and then
back over the part 3 of the partition a', which is gapped out at this end, to the
propeller, and again forced along.
In action, the cooling liquid is drawn through. the pipe from the tank a
by the pump h, and forced through the pipe 2 into the end pipe or header g. From
this it is distributed along the pipes f, from whence it Hows by the discharge
orifices f' onto the textile sheets c, saturating them on both sides, and flowing
down them into the tank again, to be re-cooled. Two wetted surfaces are thus
provided by each sheet; and the air to be cooled is forced by the blower d into
the chamber e, and along the parallel or nearly parallel spaces between the
wetted surfaces of the sheets e; and in passing along and over these cold wetted
surfaces, becomes cooled, and is discharged at the required temperature into
the outlet o, leading to the space or chamber to receive it. From this chamber
or space the air is again returned to the cooling apparatus through the "cold
air return passage p.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is: -
1. Apparatus for cooling air for refrigeration purposes, comprising vertical
parallel or nearly parallel sheets of textile material (c) extending between the
upper and lower part of a chamber, and a series of pipes at the upper part adapted
to distribute or supply the cooling fluid onto the sheets, down which it is adapted
to flow; the air to be cooled being moved or forced into and along the parallel
spaces between the sheets; substantially as and for the purposes set forth.
2. In apparatus for cooling air for refrigeration purposes, a series of liquor
distributing pipes f, and parallel or nearly parallel sheets of textile material, c,
carried by said pipes, and disposed within a chamber e; substantially as and
for the purposes set forth.
3. The air cooling apparatus for refrigeration purposes having parts arranged
combined and adapted to operate particularly as set forth with reference to,
and shewn in the drawings.
