This invention relates to apparatus for vwarming, cooling or otherwise conditioning air, and has for one of its objects theuprovision of`a simple, compact and inexpensive apparatus vparticularly well adapted for conditioning the air of isingle rooms, although of course not limited to single rooms, the apparatus being of such a nature that it can be installed near kthe ceiling where it is out of the way and does not present an unsightly appearance. I
In the drawing accompanying the application: Fig. lis a view showing the apparatus installed;
, Fig. 2 is a section on the line 2-2 ot Fig. `1; snrvl'ig. a is nyseotion on the iine i-l-s, or Fig. 2;'
Fig. 4 is a sectional elevational view of a modification.
Referring to the drawing in detail, my conditioning apparatus includes a casing comprising a body portion I within which I mount plates referred to hereinafter ias/'conditioning plates. 'I'hese plates designated 2 and 3 are of corrugated metal extending from top to bottom lof the body portion I of the casing of the apparatus. These plates which are wound or bent inthe form of a spiral are spaced apart by lugs I.
The space between the plates 2 and 3 is for .the circulation of 'either a cooling medium such -as cold water or awarming medium such as warm water, this conditioning mediumvbeing admitted to the inner end oi' the spiral through The water circulates through the spiral space between the plates 2 and I and discharges from the apparatus through pipe B which may lead back tothe supply. It will be understood that my apparatus comprehends the use `of fluids I. by electric motor 8 mounted on the bottom of.v
other than water. 'I'he air to beconditioned is drawn into the casing I lby a f an 'I mounted at the top of the 'apparatus immediately above the center of the apparatus. fan being driven the casing.
In the convenient arrangement show'n in Fig. 1
. air isdrawn from the room 9, upwardly through duct Il in one wall thereofthrough intake II provided by the plates 2 and 3, counteriiow to the conditioning medium, nally being dis- Icharged by the fan I through duct I2 baci:- into the room 8 again. y As mentioned above the fan 'I is driven by a motor l secured to the bottom I3 of'th casing I of the apparatus, the shaft of this `motor ex-.
tending upwardly through the space Il in the center of the apparatus.
'I'he lower end of the conditioning platesv 2 and l may be closed by channel members Il welded or otherwise secured to the bottom |315` of the casing ofthe apparatus while the upper end of these plates may be closed by similar channel members I5 welded o r otherwise secured to a plate I6 across the top of the casing, this plate I6 and the cover II of the casing being 10 sealed at I8 to the body portion ,I of the casing. The fan 'I is completely enclosed as shown.
'I'he intake II of the device or apparatus as seen in Fig. 3 extends from top to bottom of the apparatus and at this intake opening I provide 15 a removable filter which ignay take the form oi a wire mesh tube 20 illled with any suitablematerial 2|, such as cotton for example. Y
The tube 20 may be removed from time to time and the nltering. material 2| replaced or 20 cleaned. I
'Ihe conditioning fluid, for example, water, and which may be taken froma suitable source of supply, 4circulates throughout the entire space provided by spirally winding the plates 2 and 25 l and inasmuch as these plates additionally are of corrugated metal, it will be seen that the conditioning iluid is obliged to contact with a very large surface. By the same token the air tobe To reduce the speed ofthe air passing through 35 theapparatus to insure its thorough cooling or heating, as the case may be, I provide bailles 22 in the space between the convolutions oi' the spirally bent plates 2 and l.
In the modification shown in Fig. 4 I have pro- 40 vided a construction similar to that already described, in that I employ corrugated metal plates '2 and vl wound or bent into a spiral. In this construction additionally I employ pipes 23 which are wound spirnuy, met in one direction and 45 then in the opposite and laid between the plates 2 and 3. This construction is advantageous where the conditioning iiuid is under pressure, it being understood that in this embodiment of the invention .the conditioning .uid is circulated 50 through the pipes 2l lying. in the space between the plates 2 and 3 instead of merely throughhthis space as in the ilrst form described. v It is to be understood that changes may made in the details of constructioinand arrange- 55 ment of parts above described within the spirit and scope of my invention.
