The device, the subject of this invention we ' quired for operating the blower motor and as it
term an air conditioning apparatus and’ for the is entirely portable, it is provided with a casing
formed in two major parts. The part indicated
reason that it performs a number of the func
at l we willrefer to as the upper casing, and the
part indicated at 2 we will refer to as the lower U1
tions that are important in air conditioning.
Air conditioning in its broadest sense, consists
of a number of treatments depending of course
upon the initial condition of the air and the con
ditions required at the time that the condition
ing or treatment is completed.
The present apparatus and the one which we
10
were about to describe will accomplish a number
of the desired purposes, such for instance as
?ltering the air if that is desired, of dehumidify-
casing.
-
Within the upper casing I we arrange a con
tainer 3, which maybe adapted to receive solid
CO2 sometimes referred to as dry-ice, or water
ice or even cold water, and this container is pro- 10
vided with an efficient cover or closure 4, resting
upon a gasket 5, the gasket in turn resting upon
a lip or ?ange 6 of the container 3. We desire '
ing the air, of cooling 11; during dehumidmcation
that this‘ container be not in contact with the

has been ?ltered, cooled and dehumidi?ed. Our

purpose of distributing the air and we pro

Our air conditioning device is entirely port

into the device and materially increasing the e?i- w50
ciency of the device, both as an air cooler and a
dehumidi?er.

At the intake side of the fan we provide a
screen l5 which'may or may not be an air ?lter
as shown in Figure 6. We prefer however that it 55

should to an extent at least ?lter the air. For
ward of the fan is a ba?ie shown at E5 and
intended'to direct the air out of the horizontal
to a verticalcourse, changing the direction of the
Cl air flow may and probably does reduce the speed
and volume of the air, but it also accomplishes a
more important purpose, it insures that all of
the air discharged from the fan will pass between
the ?ns or plates II and will because of the
10 peculiar shape of the plates, remain in contact
therewith an appreciable period of time, with
the result that great cooling and dehumidi?ca
tion results.
Leaving the fan I3, the air travels upward
directed by the ba?ie l6 and between the plates
II and is discharged through a shutter aperture
II‘. In both ?gures the shutters are shown
closed, but the dotted lines i8 in- Figure 2 sug
gest that the shutters may be opened to direct
the air as desired, the shutters being operated
by the handle l9, operating a link 20 to which all
_, of the shutters ‘are connected by means‘ of bell
crank levers as shown at M, so that the shutters
operate simultaneously from the single lever l9.
25, The upper portion of the casing i is supported
upon the lower casing member 2 as shown in
Figure 2, but is insulated from the lower casing
by a gasket 22 not only for the purpose of con
serving energy, but for the purpose of quieting
30 the device by dampening the mechanical vibra
tions. The lower casing member 2 is provided
with a shelf 23 to which the upper casing member
i is secured. , The lower casing member projects
upward slightly above the juncture of the two
and forth behind the lower edges of the fan l3.
When water ice is used possibly no appreciable
cooling of the air will result from this circuitous
arrangement of the pipe 21, but when dry ice is
used the passage of the gas through this pipe will
assure that all of the cooling effort contained
even in the gas, will be removed and thegas
will be discharged only after its usefulness has
been exhausted.
To obtain the highest possible ef?ciency, a
direct metallic contact of the plates H with a
refrigerant is desired. We may accomplish this
as previously stated, but another way and that
shown in Figure 5 is to have the plates ll ac
tually pass through the bottom of the container 3.
Each plate is then bent over at the top as indi
cated at “b” and may then be secured in place
by soldering, thus'the refrigerant rests immedi
ately upon the plates and the maximum cooling
effect is obtained.
‘
In Figure 6 we show a device of somewhat
di?erent construction. In this device the casing
31 is continuous, that is it is not a two part
casing. The front panel 33 is however arranged
at an angle at the point where the air'is dis-v
charged. The fan or blower 39 in this construc
tion is arranged at an angle and this makes it
possible to employ continuous ?ns or plates as
shown at 40, these plates being secured to the
refrigerant container 4! in any manner desired,
but it is very desirable that the connection be
tween the fins or plates 40 and the refrigerant
container, be a good thermal conducting joint.
The-plates or ?ns, an end elevation of whiph
casings and the space 24 between these two ' is shown in Figure 7, are corrugated as indicated
basings allows any moisture of condensation that
might collect on the upper casing to pass down
Ward to the lower casing 23, from whence it is
at 42, and while such corrugations will slow down
the passage of air to a slight extent, they will
also assure that the air will contact with the
allowed to drip into a suitable container. If plates and that no air ?lm will form on the
dry-ice is used as the refrigerant, it is desirable plates. As a. result of recent experimentation,
to introduce air into the refrigerant container we are led to believe that corrugated ?ns or

The discharge of the gas is through the pipe 2‘!
and this pipe is controlled by a valve 28, which
50 valve will be allowed to remain open if dry-ice is
employed, but will be closed it water-ice is em
ployed, except at that time that it is desired to
draw off the water.

The space M between the refrigerant container

construction closed by means of a member 135 '
of a desirable shape. In closing this space we
depend upon dead or impounded air as the in
may be discharged into the drawer 29 by opera
tion of the plunger operated valve 28. The switch
