Description

June 4, 1929. R. HARDY AIR COOLING DEVICE Filed April 10 Patented June 4, 192.9.`
UNITED STATES BULAN HARDY, F ORLAND, CALIFORNIA.
AIBrCOOLING DEVICE.
Application led April 10,
This invention relatesto a device for cooling the air in rooms.
' An object of this invention is the provision of a device of the character mentioned by` lwhich airis cooled by the evaporation of a liquid, preferably water.
Another object of the invention is the provsion of a device whereby the air in a room may be cooled by evaporation without increasing the humidity of the cooled air.
. A further object of the invention yis the Vprovision of means for effecting a forced draft to increase the. rate of evaporation of theliquid which cools the air by its evaporation.- i Y With the foregoing objects in view, together with such other objects as may subsequently appear, this invention 'resides 1n the construction and arrangement of parts hereinafter described and claimed, and' illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my air cooling device, partly broken away.
Figure 2 is a horizontal section taken on the line 2 2 of Figure 1.
Figure 3 is a fragmentary section taken on the line 3 3 of Figure 1, and -f Figure 4 is a fragmentary section taken on the line 4 4 of Figure 2.
Referring to the drawings for more detailed description thereof, the device-0f my invention comprises a container having sides 5 and 6, bottom strips 7 joining the sides 5 and 6, top strips 8 joining Ithe s1des 5 and 6, a rear wall 10 and a front wall 11. A11 aper- -tured vertical plate -12 is disposed near the rear end, and another vertical apertured plate 13 is disposed near the forward end of the i device. Spaced horizontal apertured plates yl5 and 16 extend from' the vertical plate 12 tothe forward part of the device. The plates 15 and 16 have spaced apertures running from the plate 12- to the plate 13 and extend th/ereacross. Between the plates 12 and 13 and above the plate 15 spaced ducts 18, made of metal and Lcoveredlwith aponous material such a burlap, are disposed, the upper series of ducts resting on the late 15 and held by the cross strips 8, and t e lower series resting on the bottom strip 7 and -held by the plate 16 between the apertures of the latter plate.
' The spaces-between both the upper and the lower ducts 18 aredesignated 19. Communicating with the u perserles .of ducts 18 is a duct 20 which lea s intoA a room,
partment 28 and 192s. seran no. 101,214.
preferably into ltheupper part of a room,` to which, of course, the hot air rises. Communicating with the lower series of ducts 18 is a duct 22 which leads to the same room as that to which the duct 20 leads to, this duct 22 preferably leading tothe lower part of a room. f Afan 25 is placed in the duct 22 and draws-warm air from the room down through the duct 20, through the upper series of ducts 18, back into the compartment between the rear wall 10 and the plate 12 and thence into the lower series of ducts I18, forwardly intoy the duct 22 and back 'into the room, as indicated by the varrows 26.1in unbroken lines.
which are alternately disposed relative to the ducts 18. The airis drawn through the ducts 19 by afan 27 disposed in the duct 28 formed by the plates 15, 16 andv the rear wall 12. The fan 27 causes air tomove in the directions indicated by the arrows 29 shown in broken lines. This air is drawn from the atmosphere outside the room to be cooled and passes through the ducts 19 into' the chamber or comthence back into the atmosphere. y
Transverse pipes 31 having apertures therethrough are connected with a 'water line.
The water passes through the aperturesin the pipe 31 -and wets the porous material which surrounds the ducts 18. The evaporation of the'water from the porous material cools the pair passing through the ducts 18 and the passage of air through the ducts -19 hastens the evaporation from the porous ma-i terial and thus more quickly cools the air 95 vwhich is circulated through the room, andv vthrough the ducts`18.
Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of-va.- v rious changes; and I reserve the right to employ suchas may come within the scope of the appended claim. i
- claim: v
An air cooling device comprisinga casing having three compartments disposed above each other, longitudinally extending air conveying pipes disposed in the ltop and bottom compartments, an air inlet communicating with the upper set of pipes, an air passageway placing the upper set of pipes in communication with vthe lower set, an air outlet communicating with the lower set of pipes,
- a fan disposed in said outlet, a porous material wrapped around said pipes, means for saturating the material with water, the walls of said central compartment having openings communicating with the upper and lower compartments, a fan disposed in said central 1n ,through the upper and lower compartments .causing a quick evaporation of Water from the porous material.
