Pa., a corporation of Pennsylvania Application Februaryzi, 1940, serial No. acuosa (ci. ca -129) 5 Claims.

My invention relates to air conditioning apparatus, more particularlyv to a unit air conditioner adapted to be mounted in the window of a room, and itl has for an object to provide improved apparatus of the character set forth.

A more particular object is to provide animproved structure for housing and mounting an air conditioning unit, more particularly a simpler structure involving less material and therefore less expensive to manufacture.

A further object is to provide a housing and mounting structure affording convenient access to the air conditioning apparatus contained therein.

These and other objects are effected by my invention as will be apparent from the following description and claims taken in connection with the accompanying drawing. forming a part of this application, in which:

Fig. 1 is a perspective view showing the unit air conditioner mounted in a window; and,

Fig. 2 is a perspective view showing the mounting structure'and the refrigerating unit removed from the mounting structure.

Referring to the drawing in detail, I show a unit air conditioner indicated generally-by the numeral I and adapted to be mounted in the window of room for the purpose of cooling and dehumidifying or otherwise conditioning the air of a room. In accordance with the present invention the elements of a refrigerating system which serves to cool and dehumidify the air are mounted as a unit on a base member II to form a refrigerating or air cooling unit I2. I Such elements include an evaporator I3 extending across the front of the unit, a condenser I4 extending across the back of the unit, and a motor-compressor unit I5 disposed just forwardly of the condenser. The refrigerating system further in-v cludes suitable conduits and all other parts necessary to form a complete and operative refrigerating system. An upstanding partition I6, of the form shown in Fig. 2, is mounted on the base member II to form a division between an evaporator compartment I1 at the front and a condenser or machine compartment I8 in the back. A fan I9 disposed in a fan shroud 2i serves to introduce flow of air from outdoors through the left-hand half of the condenser into the machine compartment and to discharge the same to outdoors through the right-hand portion of the condenser. A fan (not shown) disposed in a fan shroud 22 is adapted to induce ilow of air from the room inwardly through the right-hand portion of the evaporator into the evaporator compartment I 1 and to discharge the same into the room through the left-hand portion of the evaporator. As will be noted from Fig. 2, the unit I2 is open on the two opposite sides and on the top.

To mount the refrigerating unit I2 in the window, I provide a mounting structure indicated generally by the reference numeral 23. In accordance with myinvention, I further utilize the mounting structure 23 as a casing or housing for the unit I2, thereby dispensing with the need of providing a casing on the unit I2 itself. 'I'he mounting structure 23 comprises side walls 24 and a top wall 25. These walls are substantially imperforate and extend from the front to the back of the apparatus. Angle irons 26 are secured tol the lower edges of the side walls 24, as by spot-welding, and provide horizontal flanges 21 on which the unit I2 is supported.

.Inasmuch as the base member II forms a closure for the bottom of the unit air conditioner, it is not necessary that the mounting structure 23 comprise a complete bottom wall. However, a suitable connection between the lower edges of the side walls 24- is preferably provided to make the mounting structure more rigid. Such connection may comprise an angle iron 28 and a wall portion 29, which are preferably spaced to provide an opening 30 for admission of fresh air t0 the cabinet.

The mounting structure 23 is fastened in the window in any suitable manner. In the illustrated embodiment, the downwardly-extending ange of the angle iron 28 engages the outer edge of the window sill, and suitable clamps 3|, removably. secured to the bottom of the mounting structure, engage the inner edge of the window sill., An angle iron 32 is secured to the top wall 25, as by spot-welding, and disposed to provide an upwardly-extending flange which is adapted to engage the inner side of the window sash. Removable and adjustable clamps 33 are secured to the top wall 25, as shown on the drawing, and are adapted to engage the outer side of the window sash.

To mount the unit air conditioner in the window, the mounting structure is first secured in place. To do this, the mounting structure is first, placed on the window sill in the position shown and the clamps 3| are tightened. The window sash is then brought down and the clamps 33 tightened, so that the mounting structure is securely held in the window as shown on the drawing. Any open spaces left between the sides of the mounting structure and the window may be closed in any suitable manner as well known in the art. After the mounting structure has been securely fastened and placed in the window, the refrigerating unit II is positioned therein by merely inserting it horizontally through the front of the mounting structure and sliding it rearwardly therein. When the unit is so inserted, the upstanding partition I6 cooperates with the side walls 24 and the top wall 25 and the base member Il to form the evaporator and condenser compartments I1 and IB already referred to, the side and top walls of the mounting structure thus forming the sides and the top of the compartments l1 and I8. The fans referred to above are then effective to induce flow of air from the room and from outdoors into the respective compartments.

A rubber or other suitable gasket, partially shown at 34, extends along the top and side edges of the partition I6, being preferably attached to anges extending along said edges. This gasket contacts the inner surfaces of the

walls

24 and 25, thereby providing an air seal between the compartments I'l and I8.

A wood cabinet member 35 may be placed over that portion of the air conditioner which is on the interior of the room. This cabinet member includes a series of louvers in the front to provide for admission and discharge of the air flowing through the evaporator, as indicated by the arrows in Fig. 2.

From the above description it will be seen that the construction of the unit air conditioner has been simplified and its cost reduced in that the mounting structure serves two purposes; namely, to mount the unit in the window and also to form a casing or enclosure therefor. A further advantage is that the unit can bev very easily withdrawn from the mounting structure and when so Withdrawn the several elements of the apparatus are readily accessible for inspection, repair and servicing.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
