ATTEI RN EYS United Sates HIGH SPEED AIR CONDITEONER CIRCULATING CHAMBER Calvin M. Jones, Miami, Fla. Application May 14, 1953, Serial No. 355,087 Claims. (Cl. 62-440) a cylindrical coilwith vertically disposed wire mesh strips.

woven through the coil and with air circulated from the periphery of the coil discharged into incoming air and recirculated with said incoming air.

The purpose of this invention is to provide an air conditioner that handles a comparatively large volume of air whereby fresh air only is circulated through the device and the necessity for recirculating air of a room or other enclosure is eliminated.

With the. conventional type of air conditioning. system air of a room or other enclosure is, drawn into an air conditioning. unit and discharged into the room 01 enclosure from which it is drawn. By this means the same air is. reused or recirculated and the use of fresh air, continuously, in air conditioningunits hasnot been considered practical because it is impossible, with con-. ventional units to circulate a sufiicient quantity of air. With this thought in mind this invention contemplates an improved air conditioning unit through which a comparatively large quantity of air is circulated and which is so constructed that the air contacts both inner and outer surfaces of a coil, with the air being retained in suspension on both sides of the coil with wiremesh.

The object of this invention is, therefore, toprovide means for constructing an air conditioning unit whereby a sulficient, quantity of air is circulated and treated to make it possible to use only fresh air, thereby eliminating the necessity of recirculating foul air.

Another object. of the invention is to provide'a-high speed air conditioning unit that is also adapted to be used as a cooling device particularly for cooling fluid of compressors, engines, and other power devices.

A further object of the invention is to provide an air conditioning, circulating and distribution unit that is adapted to circulate comparatively large quantities of air and that is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a cylindrical outer housing having an open upper end, an inner casing concentric with and spaced from the outer casing and supported with the lower end in spaced relation to the lower end of the outer casing, a substantially cylindrical coil concentric with and spaced inwardly from the inner casing and having a fmstro-conical shaped shell extended downwardly from the lower end thereof, vertically disposed wire mesh screens interwoven with the coil, a cylindrical screen around the coil, a circulating fan positioned in an opening in the lower end of the inner casing, a cylindrical skirt extended downwardly into the upper end of the outer housing and positioned between the inner casing and outer housing and a circulating duct extended from said skirt.

The inner and outer surfaces of the coil Mare covered with vertically disposed'wir'e mesh: sereens-32 and: 33' and an additional-screen,- as indicated by'theprovided-onthe outside. sections=32and-' 33 are woven through the coil;'-as illustrated in Figure 4, and the upper ends are secured to a band 31 by rivets or the like.

The coil is also provided with vertically disposed strips 35 and the ends of the coil extend through the inner casing, skirt, and outer housing providing connections 36 and 37 by which the coil may be connected to a com pressor or the like. It will be understood, however, that the connections from the coil may extend through the parts of the unit at a difierent point or at diiferent points and also that the coil may be covered with other suitable screening or filtering elements.

The outer surface of the coil is also provided with spaced vertically disposed stays 38 which extend from the band 31 to the lower end of the shell 11. A band 39 is also provided around the outer surface of the cylindrical screen 34 and this band is connected to the lower ends of the strips 35.

The coil is also provided with a spiral vane 48 which is supported from the inner surfaces of the coils with connectors 41, as shown in Figure 4.

With the parts arranged in this manner the fan or blower 16, which is provided with eificiently formed blades circulates the air at high speeds as indicated by plan throughv theunit. takenv Figure 5 is a detail illustrating the. connections-to the:

The cooled air passes from the duct to points in a building or the like.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
