1 Claim.

This invention is-directed to the provision of portable air conditioning equipment which is very efflcient in operation, compact and simple in construction and relatively inexpensive in operation.

The accompanying drawing shows an embodiment of the invention in part sectional elevation.

Referring to the drawing in detail, I designates an enclosing cabinet divided by transverse partitions 2 and 3 into an air conditioning chamber 4, a motor and condenser chamber 5 and a compressor chamber 6.

The air conditioning chamber 4' is provided with air intake grilles- 1 formed in the walls of. the cabinet I and with a discharge throat and air discharge grilles 8 and 9 at the top of the cabinet. e

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 and over and around the conditioning coils or 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 the room or enclosure in which the cabinet is located. The fan II is driven by a vertically disposed motor l2 which is within the conditioning chamber 4 and mounted on springs IS on the upper face of the partition 2.

In the lower chamber 6 o! the cabinet is the compressor It, the compressor being supported on spring mounted frame l5, which extends into the intermediate chamber 5 where it supports an electric motor l6. g

The compressor I l and motor l6 are mountedvertically and in alignment with each other.

In the chamber 5 and surrounding the motor i6 is an air cooled condenser H. The upper end of this condenser is connected by tubing I8 to a tank I9 which is connected by tubing 20 to the discharge side of the compressor Hi. The otherend of the condenser is connected by tubing 2| to a tank 22. The tanks l9 and 22 are disposed in the chamber 6 of the cabinet I.

The conditioning fluid which is compressed by the compressor I4 is forced through the condenser and liquefied, the liquid passing into the tank 22 from which it is forced by the pressure in the system through the tubing 23 which extends from the interior of the tank 22 near the bottom thereof upwardly through the cabinet to the intake end of the conditioning coils III in the chamber 4. The tubing 23 is provided with an expansion valve" 24. The conditioning fluid after circulating through the conditioning coils I!) returns to the intake side of the compressor by tubconduit 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 chamber 6 of the cabinet I by a fan 2'? which is 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 discharged out of the cabinet after passing over the coils of the condenser ll throughconduit 29.

The above described device is very simple and inexpensive in construction, the vertical mounting of the compressor I 4, its drive motor l6 and the. vertical mounting of the separately controlled motor H which drives the air fan It conserving floorspace 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 device is located may be circulated without the necessity of running thecompressor It.

It will be appreciated, furthermore, that by 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 the fan H when it may not be necessary to run the compressor it both fan and compressor are necessarily driven due to the fact that one motor is employed for driving both.

It is to be understood that changes may be made in the details of construction and arrangement of parts hereinabove described and illustrated in the accompanying drawing without departing from the spirit and scope of my invention.

What I claim is:

Air conditioning equipment comprising in combination an enclosing casing provided at its upper end with an air conditioning chamber, air conditioning coils in said chamber, an electric motor vertically disposed in said chamber, a fan in said chamber driven by said motor for drawing air into said chamber and discharging it therefrom, a compresso fla motor for driving the same and a condenser insaid casing below said chamber, said compressor and motor being vertically disposed and in vertical alignment with each other and with said first mentioned motor and fan, said condenser being connected to said conditioning coils, operation of both motors effecting circulation of conditioning fluid through said coils and the passage of air into the conditioning chamber about said coils and the discharge of conditioned air to the exterior of said casing, the first mentioned motor being operable individually to eflect air circulation without conditioning.
