Application July-:23; 1946, Serial No. 685,749

3 Claims. (cuss-.12).

This; inventionrelates improvements in. air conditioningunits;

The primaryobject of the invention isto provide an air conditioning; unit that will eithercool or heat the-surrounding-area.

further object; of: the invention is. to wash, cleanse and; sterilize thet-airr taken into the unit and: delii'er'fresh; airtherefrom either heated or coo 'o tort its:eXi i a cmp ure;.

A still further object of the invention is the provision; of meansionhumidifying the air being delivered through the machine.

And a further object of thev invention is to provide automatic controls for controlling the operation ofzthe unit;

These and other incidental objects will be apparent in the drawings specifications and claims.

Referring to the drawings:

Figure 1 is a front view of the air conditioner; parts broken away for convenience'of illustration. In this particular view the refrigeration feature is being used-in connection with the air cleansing, humidifying and sterilizing features. v

Figure 2' is a plansectional view, taken on line 2-2: of Figure 1-, looking down into the refrigeration coils submerged within the liquid containing tank.

Figure.3 is a fragmentarysectional view, taken on line. 3-3 of Figure,1, illustrating therefrigeration coils and the suction foot of the pump.

Figure 4 is a fragmentary front view of the air conditioning unit wherein heating coils are installed for the heating of the air.

Figure 5 is a fragmentary sectional view, taken on line 5--5 of Figure 4, looking in the direction indicated.

Figure 6 is a perspective front view of the air conditioning unit illustrating the same as connected up to a refrigeration unit. The broken lines indicating the connections for the heating unit when installed.

Figure 7 is a fragmentary plan sectional view, taken on line of Figure 4, illustrating the discharge nozzle of the fan.

In the drawings:

My new and improved air conditioning unit consists of a cabinet I divided by a vertical partition Ia to form two compartments 5 and 5a. The lower end of the partition terminates above and spaced from the bottom of the cabinet to provide a passage 5b between the two compartments 5 and 5a. A conventional type blower fan 2 is mounted in compartment 5a underneath the top 3 of the cabinet. A suitable driving motor 4 is mounted within the compartment 5 of the cabinet and. drives: the; fan; 2 through the; belt 63- from the pulley 1 to the driven; pulley.- 8:. keyedto the countershaft: 9...

The; mechanism for which Ido-nota t mnt: o Show The; cooling; coils [8; are; connected to. the refrigeration unit, I9 throughsuitable, pipe 20. The water;- I. aintai ed. ata. low temp ature by the; refrigeration coils and; is delivered fromv the tank; l2- throughthe-piping 2|, pump 22, piping 23zoutthrough thespray nozzles-2.4 and directed downwardly; through the screens. 25 and back downinto the pan 12 for recirculation. The screens, are for the purposepf. breaking up the water assisting in. the. cooling, washing and cleansing effect.

The operation of; the blower or fan 2. draws air throughthe, adjustable grill '26 and up. through the screens,ZSandthrough thefilter. unit 2'! into the fan at 28 and discharging the same, through the fan nozzle 29, thence through the grill into the surrounding area, as for instance a room to be cooled. The pump 22 is driven from the motor 4 through the belt 3|. The operation of the motor 4 is controlled by a suitable thermostatic control 32, which I show diagrammatically in connection with Figure 1 for clearance of operation, although this is not the way the wiring would appear. A control switch 33 may be operated by hand or automatically by the thermostatic control 32 stopping or starting the motor.

I have just described the air conditioning operation as having been used for cooling, cleansing and sterilizing and humidifying. When it is desired to use the same as a heating unit together with air cleansing and. humidity control, the screens 25 are removed and the radiator unit 34 is installed in their place. The radiator 34 receives circulating water or steam through the piping 35 from the hot water or steam tank 36, the detail of which I have not attempted to go into mechanically, as any suitable source of supply may be used in connection with my air conditioning unit. When the heating radiator 34 is used the pump 22 may continue to supply Water over the surface of the heating unit as required to add humidity to the air, but excellent results are obtained where the belt 3| is removed from the motor and the pump and the air coming in through the air intake grill 26 passes over the surface of the water l3 within the tank 12 causing the same to evaporate up through the heating radiator 3|, which heats the air which then is delivered through the filter 21 and the fan unit 2 as above described.

One of the outstanding features of my invention is the including of a sterilizing unit 31; in the path of the air. This sterilizer unit may have a medicinal material contained 'therein, andit may be located at any desired'location within the air conditioning cabinet but in the path of the air that is being conditioned and discharged,

Many combinations may be added by the inter changing of the various parts within my air con ditioner, but the combination I have just described provides' the necessary-features to fulfill the objects of 'my invention; 1 r I do not wish to be limited to the exact mechanical structure shown and described, as other mechanical equivalents may be substituted still coming within the scope of my claims.

What I claim as new is: a r

1; An air conditioning unit, including a cabi-, net, a partition extending from the top of the cabinet and terminating short of the bottom of the cabinet, an air-cooling tank extending across the full width of the cabinet, an air' inlet grill in the wall of the cabinet immediately abovethe air-cooling tank,-means forvarying the temper ature conditions and supported in-the partition and one side wall of the cabinet, a spray means between the partition and cabinetwall, a. filter supported betweenthe partition and cabinet side wall, an air outlet grill at the upper end of the cabinet for delivering air to the exterior ofthe cabinet, a fan at the upper end of the cabinet between the partition and cabinet wall for delivering air through the air outlet grill, 9, motor for the-fan between the partition and cabinet side wall on the sideof'the partition opposite the fan, a pump on the side of-the partition with the motor, a pump inlet leading' from the air cooling tank, a pump outlet leading to the spray means, andan independent pump drive from the motor.- 1

cabinet and above the air inlet grill, a spray 'means between the partition and cabinet side wall, a filter supported between the partition and cabinet sidewall, an air outlet grill at the upper end of the cabinet for delivering air to 'the exterior of the :cabinet, a fan at the upper end of the cabinet between the partition and air outlet grill and including a shaft journaled in the partition, a motor for the fan between the partition and cabinet side wall on the side of the partition opposite the fan, a pump on the side of the partition with the motor, a' pump inlet leading from the air cooling tank, a pump outlet leading to the spray means, and an independent pump drive from the motor.

3. A' construction as defined in claim 2, the screens on removal providing for the support of selective air treating means of a character' to cooperate with all parts of the unit other thanthe screens.- I
