3 Claims.

My invention relates to an apparatus for cooling and conditioning air and the object of my improvements is to insure greater efficiency than has been obtained by devices designed for a like purpose,as now employed.

I obtain this object in the apparatus shown in the accompanying drawings, in which:

Figure 1 is a perspective view of an apparatus embodying my invention.

Figure 2 is an elevation of the same in longitudinal section,in the plane taken on the dot and dash line 2-2 of Figure 4,and shown connected with a hot-air furnace.

Figure 6 is a perspective view showing a modi- In the form shown in Figures 1, 2, 3, 4 and 5, g

'the apparatus may be located in' the basement and the air taken from an upper room through a descending conduit A and delivered to the distributing system D of the furnace F, througha delivery pipe B ;--water being supplied from service pipes-not shown-under control of a float actuated conical valve C. The supply of air delivered to the intake of the fan casing, may be regulated by a damper E, manipulated from an upper floor by a rod e.

Referring ,in the first place more particularly to Figures 6 to 10 inclusive:

The numeral 2 denotes an approximately rectangular casing having atits ends the downwardly extending pedestals 2d and 2b. Said casing is divided into an upper compartment 3 and a lower compartment 4 by a partition 5, which is bent downward at the right to serve as-the upper wall of the intake passage and at the left at 5a. it is bent upward over and downward to form a put of the wall of a passage for delivering and adapted to the passage 3a.

air into the upper compartment 3. The numeral 6 indicates an intake passage opening, preferably from the inner side of the pedestal 2a,, and extending upward and then horizontally to about the center of the casing '2, along the partition 5 forming the bottom of the compartment 3 and a part of the wall of said passage. The numeral I indicates a centrifugal fan having the casing 8 in which its axis is'eccentrically located. The casing 8 is open at its outer end to the compart- 10 ment 4, and its delivery passage 8a extends to the part 5a of the partition 5 to form therewith a passage opening downward and inwardly, into the compartment 3.

The numeral 9., (Figure 9) indicates an elec- H trio motor for operating the fan I. III, I0 are cylinders of wire meeting in the compartment 3 secured upon a shaft resting in bearings parallel to the shaft of the fanl. The numeral indicates a belt passing over pulleys on the shafts w the upper portion of the end wall of the casing 2 int'o'the. compartment 3 sloping gradually down-.

, ward, and then bends abruptly downward to bring the lower edge I2a at a slightly lower level thanthe inner edge of the wall 5a. This forms the enclosedj'air space I3}, and the wall 5a forms a 35 similar enclosed air space I4 atthe other end of the casing 2. The numeral I5 indicates a reservoir to contain water to supply the same to the compartment 3 as required. The top of the compartment 3 is also the bottom of the reservoir 'I5,--except where the passage 3b passes through the top'wall of said compartment. The numeral I6 indicates a vertical opening through the center of the reservoir I5, and I 5a. is a filling passage for said reservoir. The numerals 3a. and 3b indicate consecutive connecting discharge passages leading from the compartment 3 and to the opening I6. The passage 3a has the partition I2 for its lower wall and the top of the compartment 3 for its upper wall. 50

The numeral I'I indicates diaphragms of wire netting extending transversely across the. compartment 3, between the cylinders I0 and the partition I2, and H11 are similar partitions in Said diaphragms 5 are hinged at their upper edges and slant downward and forward in the direction of motion of the air.

The numeral [8 indicates a rod pivotally connected to the diaphragms l1 and Ila, and pass ing through the end of the tank 2 is provided with a handle l8a on its outer end. The angle at which said diaphragms may be adjusted is controlled by manipulating the rod l8. Diaphragms 11b in the upper wall of the passage 3b slant downward and in the direction of the air flow, and are cut away at their lower edges, and alternate with diaphragms cut away at their upper edges, so as to deflect the current of air toward the upper and then the lower wall of the passage 3b.

The water supply apparatus C keeps the level of the water in the compartment 3 at the level of the lower edge of the partition 5 where it extends into the compartment 3 at 5a.

The operation of the above described apparatus is as follows:-

The fan I is rotated by the electric motor which also rotates the cylinders 10 through the belt II, and the pulleys and the respective shafts.

The fan 1 takes air from the compartment 4, through an open end of the casing 8 and discharges it into the compartment 3 through the passage 8a in a downward and slanting direction against the surface of the water in said compartment. The air is forced by, and through the interstices of the cylinders l0. These cylinders dip into the water at their lower portions and carry the water up in films across the spaces of the netting, and the current of air passing this film has water removed from it.

The air passing along past the diaphragms l1 and Ila has the drops therein arrested or defiected down upon the surface of the water or upon the partition l2, as the case may be. The current of air continuing through the passage 32) is further acted upon by the partitions l1 and brought into contact with the Walls of said passage which are cooled by contact with the water in the reservoir I5.

The current of air flowing from the passage 8a draws a vacuum in the chamber I4 which causes the level of the water to rise in said chamber as shown in the drawing. The action of the air and cylinders l upon the water between the chambers l3 and I4 causes an oscillating motion thereof, the pressure of air in one of said chambers being diminished and in the other increased alternately, thus producing a cooling action on the walls a of the chamber l4 and the partition l2 of the chamber 13.

The water in the above described apparatus is contact with the partition 5 forming a wall of said passage. The air is further cooled by contact with the wall 5a of the chamber l4 and the wall 12 of the chamber [3 which have been cooled by the alternate compression and expansion of the air therein.

It may be observed that the fan I is placed eccentric to the casing 8. This secures a quiet action of the fan.

Water is thrown upon the partition l2 and evaporated from the surface thereof by the passing current and cools said partition and the air passing over it.

The operation of the apparatus, as shown in Figures 1 to 5, as applied to hot-air furnace installation, is similar to that just described, except, for obvious reasons, the descending conduit A, from an upper room to the distributing system D of a furnace F, is dispensed with. In furnace installations thewater reservoir [5, the passage 3b, and the diaphragms llb, have been eliminated;the conditioned air being delivered directly from the passage 3a, into the distributing system D, of the furnace.

Having thus described my invention, what I claim is:

1. In an apparatus for conditioning air, a compartment containing water; a passage for air having an orifice adapted to 'deliver air against the surface of the water, the wall of said passage being so shaped as to form an enclosed chamber with an open mouth below the surface of the water in said compartment; a second chamber in spaced relation to thefirst named chamber having an open mouth below the surface of said water; and means for impelling the water located between said chambers.

2. In an apparatus for conditioning air, a compartment containing water; an enclosed chamber having an open end below the surface of the water; a second chamber in spaced relation to the first named chamber having an open end below the surface of said water; a passage for air having an orifice adapted to deliver air against the surface of said water; and means for impelling the water between said chambers.

3. In an apparatus of the character described,

a compartment containing water; an enclosed chamber having an open end below the surface of said water; a second chamber in spaced relation to the first named chamber having an open end below the surface of said water; a passage for air having an orifice adapted to deliver air against the surface of the water; a fan for propelling a current of air through said passage over the surface of the water; and means for impelling the water between said chambers.
