VENTILATING APPARATUS.
Application filed March 26, 1924, Serial No. 702,070, and in Great Britain May 17, 1923.
The object of this invention is to provide means whereby the amount of air which is induced to flow into a room or circulate therein, and more particularly its humidity, can be varied. Y
In carrying out my invention I provide a casing in which is located an atomizer which forms a divergent stream or jet of compress-ed humidified gas, such as air, which is directed towards an outlet from Vthe casing, and means are provided for moving the outlet and the atomizer relatively to one another. whereby the quantity of air induced to flow through the casing and consequently its humidity is accurately controlled.
` In one form of construction th-e outlet from ther casing is formed of a cone, the position ot which can be altered by a raelr and pinion graduated 'to indicate the amount onf air induced by the atomizer under given n conditions.
The atomizer may be so constructed that the water or other liquid is sprayed or atomized by a ring of compress-ed air or other gas, means such as a needle valve being provided for regulating the quantity of liquid.
lith apparatus constructed in this man ner, if the relative position or' the atomizer and the casing outlet be vari-ed without altering the position kof thefneedlevalve,
then the humidity of the air will be varied as w-ell as the quantity ofoair induced; the humidity of the air can, on kthe other hand, be varied vby varying the position of the needle valvev without altering the relative position of the atomizer and casingoutlet. The ventilation of a room and the humidity of the air therein can consequently be maintained or altered to suit any desired condition, irrespective ot the condition of the air outside the building'.
In practice, the desiredcondition of th air in a room can usually `be most readily effected by keeping the pressure of air supplied vto the atomizer and also the quantity of water atomized constant, and by altering the position of the cone to regulate the humidity'of the induced air.
Obviously air from a refrigerating plant can be admitted to the casing.
In the .accompanying drawing which illustrates the invention, Figure 1 is aside eleva-V tion, Figure 2 a plan of Figure 1, Figure 3 an end elevation, Figure 4 a detail section to a larger scale, vand Figures 5 and 6 views of a modiiication. Y
1 is a casing at the forward end of which is located an atomizer 2 which can be supplied with water or other liquid through a pipe 3 andfwith air or other gas under pressurethrough a pipe el.
rJfhe water is conducted to a hollow cone 5, the quantity of water induced by the air being regulated by a needle valve 6 having an actuating knob 7. f
The air is led through passages 8 to an annular conical space formed between the outer surface of the cone 5 and a nozzle 9, and issues from the nozzle in the form of a divergent cone which can be humidiiied to `any desired extent by adjusting the needle valve 6.
10 represents the outer wall of a building having an aperture through which the rear end ot the casing 1 projects.
vThe `rear end of th-e casing 1 is open but can be controlled by means of a coneI 11 mounted on slides 12 which can be adjustably fixed in position on the casingiby means of wing nuts 13.
The casing 1 is also provided with an inlet let'opening into the room or building in which the apparatus is iixed.
' In order to control the quantity or' air admitted froinoutside the building or from the room, the casing is `provided with shuth ters 15,- 16, pivoted to the casing at 17, 18, respectively. -The shutter 15Y can be actuated by aV lever 19, one .end of which is adapted to engage stops on the quadrant .20, while the other end is connected by alink 21 to an arm 22 connected to theshutterl in suchA a manner that as the shutter 15 is opened so the shutter 16 is closed, and vice versa.
23 is a cone having an extension 241 slidably mounted in the casing 1. Fast on the cone 23`are racks 25 meshingfwith which are pinions 26 mounted on .shafts 27, the ends of which latter are provided with bevel wheels 28 -in mesh with' bevel wheels 29 on a shaft .30 having an actuating wheel 81,
Thecasing is alsogprovided with guidesk 32 which guide the cone. The said guides are calibrated to indicatethe amount of air which will be'induced to flow through the cone 23 ifo-r a given pressure of compressed air supplied to the atomizer, and/or calibrated to indicate, thehumidityfor a given Y pressure of `compressed air and a tion of the needle valve 6.
In the modification shown in F iguresy 5 given posiil l) and ti, the casing,r l is provided (in place oit' the inlet il) with openings i3 u'hieh can he uncovered or closed lily a sleeve il which latter provided with a pin 35 engaging a slotted lever 2)(1 Alast on the pivot 1T and so shaped that the openings h5 are closed as the shutter lo is opened.
3T shows diagrunnuaticaliif a heult-ir by means oit' which the incomiiu;1 air can be heated. 58 shows (liiurrauuuaticullV .tillen-i olf an): suitable cinistruetion which ma)1 he litted when desired. l
ln operation the amount ot air which Caused to lion' thri'inn'h the cone :223 is regulated lnvuioriue the said eene to or trom the nozzle 5) ol tue atrunizer. llfhen the. cone 23 in the position shown, the smallest amount oi' air otn'hirh the zuiparatus is eapable o'iA delivering! delivered (when air at a given pressure is employed). As the eone 2&3 is moved away 'troni `the noir/:le t), an
increasing amount o't' air induced to 'tion'.
Pret'elablyY the cone i so prinjiortioned that when it is in its ext ene 'forward position the diameter ol" the outer end thereo'l is slightly greater than the diameter ot the diii'erkn'ent stream olE eoinprc ed air (whether humidiiied or not) issuing' from the nozzle 9 atthis point.
Since the amount 0'1" liquid supplied to the aton'iizer eonstant, it the needle Valve (i be unaltered, the huu'iidity ol: the air 'lowing' through the cone i?) Avaries as the position of the cone altered. Il it be desired to keep the quantity ol air flowing through the Cone Q3 constant. but to vary the humiditiy thereof, `this is etleeted h y' adjustim;r the needle valve (i by means oit the aetuating` knob 7.
1t should be noted that 'forany given position ot the cone 23. the amount o'li air induced to flow is onlyr very slightly altered.` if at all, when the `amount ot liquid flowing' through the .nozzle 9 altered, provided that the pressure of the air supplied to the pipe #l is constant.
