1 Claim.‘ (Cl. 62-129)
This invention is-directed to the provision of
portable air conditioning equipment which is very
ef?cient in operation, compact and simple in con
conduit 26, the outer end of which may be placed
in position in a window opening, for example, and -
air is drawn through this conduit into the lower
struction and relatively inexpensive in operation. _ chamber 6 of the cabinet I by a fan 2'? which is
The accompanying drawing shows an embodi
ment of the invention in part sectional elevation.
Referring to the drawing in detail, I designates
an enclosing cabinet divided by transverse parti
tions 2 and 3 into an air conditioning chamber
10 4, a motor and condenser chamber 5 and a com
pressor chamber 6.
mounted on the drive shaft 28 which connects
the compressor It and motor iii. The air which
is drawn into the cabinet by this fan is dis
charged out of the cabinet after passing over the
coils of the condenser ll throughconduit 29.
_ The above described device is very simple and 10
inexpensive in construction, the vertical mount
The air conditioning chamber 4' is provided , ing of the compressor I 4, its drive motor l6 and
with air intake grilles~ 1 formed in the walls of. the. vertical mounting of the separately con
the cabinet I and with a discharge throat and
15 air discharge grilles 8 and 9 at the top of the
cabinet.

Within the air conditioning chamber I provide
a set of coiled air conditioning tubes 10, air being
drawn into the chamber 4 through the grilles ‘i
trolled motor H which drives the air fan It con
serving ?oorspace as will be appreciated. It will
be appreciated also that by driving the fan II
with its own motor l2 the air in which the de
vice is located may be‘ circulated without the
necessity of running vthe‘compressor It. \

It will be appreciated, furthermore, that by
pipes ill by a fan It disposed at the mouth of
the throat 8, the air being discharged by the fan
through this throat and discharge grilles 9 to
providing the fan H with its individual motor I 2
the apparatus can be operated at considerable
savingin current consumption as compared with
apparatus wherein whenever it is desired to‘ run

necessarily driven due to the fact that one motor

of this condenser is connected by tubing I8 to a per end with an air conditioning chamber, air
tank‘ I9 which is connected by tubing 20 to the conditioning coils in said chamber, an electric
discharge side of the compressor Hi. The other motor vertically disposed in said chamber, a fan 40
end of the condenser is connected by tubing 2| in said chamber driven by said motor for draw
to a tank 22. The tanks l9 and 22 are disposed ing air into said chamber and discharging it
therefrom, a compressol?a motor for driving the‘
