WILLIS H. CARRIER, 0F BUFFALO, NEW YORK, ASSIGNOR TO BUFFALO FORGE COM- PANY, 0F BUFFALO, NEW YORK.

HUMIDIFYING APPARATUS.

To all whom it may concern:

Be it known that I, WILLIS H. CARRIER, a citizenpf the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Humidifying Apparatus, of which the following is a specification.

This invention relates more particularly to improvements in apparatus used for humidifying the air in factories and other build- 7 ings where it is necessary or desirable to independently control the conditions of humidity in diflerent rooms irrespective of the temperature in the rooms.

The apparatus embodying the invention comprises a primary source of supply of saturated or humidified air and one or more auxiliary devices for supplying moisture to supplement that furnished by the saturated air, when this is necessary, the apparatus being primarily intended for use where the supply of saturated air from any cause is inadequate to sufficiently reduce the temperature and raise the humidity to the point required or where an excessive humidity is desired. Sufficient moisture can thus be supplied to give the required percentage of humidity without necessitating a corresponding reduction in temperature.

One object of the invention is to produce an efficient and desirable apparatus for this purpose which can be installed at a moderate expense, is economical in operation, and is adapted to supply air of like humidity to the several rooms of the building or to operate automatically to add humidity to the air supplied to any particular room or rooms I as may be required in order to obtain a predetermined condition of humidity in such room or rooms independently of the conditions existing in the remaining room or rooms.

Another object of the invention is to pro duoe a humidifying head, or device of improved construction adapted to supply sat-urated air at a predetermined temperature, either without free moisture or ladened with water in a finely attenuated or atomized condition for supersaturating the air, depending upon the humidity required.

These objects are attained by placing in the several rooms of the building auxiliary humidifying heads or devices which distribute in the rooms uniformly humidified air supplied to them by a humidifier common Specification of Letters Patent.

to all of the auxiliary devices, and which auxihary humidifiers are equipped with devices controlled independently by hygrostats located in the several rooms for commingling atom zed or finely pulverized water with the discharging humidified air.

In the accompanying drawings, consisting of two sheets: Figure 1 is a diagrammatic sectional plan of an apparatus embodying the invention. Fig. 2 is an elevation of one of the auxiliary humidifying devices. Fig. 3 1s a sectional elevation thereof. Fig. 4 is a fragmentary section, on an enlarged scale. thereof. I

Like reference characters refer to like parts in the several figures.

Referring first to Fig. 1, A A A represent auxiliary humidifying heads or devices located in the

rooms

1, 2 and 3 of a building, and B represents a humidifier for saturating air with water and su plying it to the several auxiliary humidif ymg devices A. The construction of the auxiliary humidifying devices A is hereinafter described.

The humidifier B, shown in the drawings, comprises a spray chamber 6; a blower o for drawing external air through the chamberand delivering the humidified air through branch pipes or conduits b b b to the several humidifying devices A; nozzles or devices I)? for spraying water into the air in the spray chamber 6 for saturating the air; and an eliminator btconsisting of spaced zig-zag plates for separating the free moisture from the air. The spray water is circulated by a pump C from a collecting well or basin in the-bottom of the spray chamberthrough a steam water-heater a back to the spray nozzle. The temperature of the spray water is regulated so that the saturated air leaving the humidifier will be kept at a predetermined constant temperature by a thermostat D which is influenced by the temperature of the saturated air and controls the flow of compressed air from a reservoir E through pipes e and e to a valve F which governs the supply of steam to the water heater so as thereby to heat the spray water more or less to maintain the temperature of the saturated air constant, as required, by reason of fluctuations in the temthe saturated air could be kept constant in other ways, but it. is desirable that this should be accomplished in one way or another, because by saturating the air at a constant ten'iperature themoisture contents of the humidified air are kept uniform.

Each of the auxiliary humidifiers A, which are alike, preferably comprises, as shown in Figs. 2%, a tubular shell or body having open flaring upper and lower ends, an air supply duct H which has a flaring open discharge end it arranged opposite to and spaced from one end of the body G, a deflector I arranged between the adjacent ends of the body G and the air duct H, and one or more spray nozzles K for moistening air which is caused to circulate through the shell and commingle with the saturated air discharged from the duct H. The air duct H, which is preferably arranged above the shell G, is connected at its upper end to one of the supply pipes for saturated air leading from the humidifier B. The deflector- I can be supported between the adjacent ends of the air duct and shell in any suitable way, for instance, by straps 2' connecting it to the lower end of the air duct, and plates 2' connecting it to the upper end of the shell G. The deflector preferably has a. conical body and an annular rim '5 which extends substantially horizontally outward from its conical body above the edge thereof, preferably beyond the flaring lower edge of the air duct and not quite as far as the edge of the flaring upper end of the shell G. The conical body and horizontal rim of the deflector cause the saturated air to be discharged substantially horizontally outward in all directions, beneath the lower edge of the air funnel, and the conical body of the deflector extending below the horizontal rim thereof forms a drip edge from which the water from the spray nozzles K striking the deflector will drip back into the flaring upper end of the spray shell. Thus the spray water which is preferably directed upwardly toward the deflector, is prevented from being thrown out into the room, and at the same time the air which is circulated upwardly through the shell G and is discharged through the space between the upper end of the shell and the deflector, is caused to pass through the water dripping from the drip edge of the deflector, which insures a thorough moistening of the air. Two spray nozzles K are shown in the device illustrated, but any desired number and kind of nozzles adapted to thoroughly wet the air can be employed. By arranging the nozzles to discharge upwardly, as shown, the discharging spray acts conjointly with the saturated air discharging from the air duct to induce a circulation of theair from the room in which the device is located upwardly through the shell G.

L represents a drip pan or basin support ed below the lower end of the shell G by straps l secured to the shell, or by other suitable means.

WVater can be supplied to the spray nozzles K of the auxiliary humidifiers in any suitable way. As shown, the pumpuG is connected by pipes at m m m to the spray nozzles of. the several auxiliary humidifiers, and pipes n a a and n connect the drip pans of the auxiliary humidifiers with the collecting basin of the main humidifier B, so that the same water can be circulated and used over and over again.

The supply of spray water to the several auxiliary humidifiers is independently regulated by valves 0 in the spray pipes controlled by humidistats 1 1n the apparatus shown, the humidistats control the action of the valves 1" through the medium of compressed air passing from the reservoir E to the valves for the several auxiliary humiditiers. through pipes p p and 19 The humidistat for each auxiliary humidifier is located in the room with said humidifier, or otherwise, so that its action is dependent upon the condition of humidity in the room. If the saturated air discharging from the duct H is alone suilicient to maintain the degree of humidity for which the humidistat is set, then the valve 0 will remain closed and shut off the spray and no water will be added to the saturated air, but if the saturated air does not give the required degree of humidity, the humidistat will cause the valve 0 to be opened to spray water into the auxiliary humidifier. The spray water, as before explained, will moisten the air of the room, which is caused to circulate up through the shell G of the auxiliary humidi fier, and the air charged with the atomized water will commingle with the saturated air from the duct H and be thrown out into the room. The humidistats in the different rooms can be adjusted so as to secure the same or different predetermined conditions of humidity in the several rooms as may be required.
