This invention relates to air conditioning and air tempering equipment and more particularly to a selfcontained unit that will be compact and easy to handle and transport. It has among its objects to provide a new and improved air tempering unit that will avoid, one or more of the disadvantages and limitations of the prior art. Another object of the invention is to provide a new and improved air tempering unit, that will be arranged for cooling air to be dispersed in a room or chamber, Without the use of conventional refrigerating equipment normally essential in apparatus of this nature.
A further object of the invention is to provide a new and improved airtempering unit employing evaporative cooling principles. An additional object of the invention is to provide a new and improved air tempering unit that will not only cool the air that is dispersed by it, but will have control of the moisture content therein. I w v Still another object of this invention isto provide a new and improved air tempering unit that will be simple in construction, economical to man'u'fa'cture and maintain, andefiective in operation, as well as afford a filtering arrangement in its structure to remove dust and objectional matter, as the air, is passed through the device and before it is distributed thereby. I
Other objects of the invention will become apparent as the invention is more fully set forth. The provision of a unit or system for the conditioning of air in a room or public space, has become an important adjunct in modern civilization. However the cost of an installation for this purpose and its operation is high, too much to appeal to families of moderate means.
This invention is intended to meet the conditions and resulting demand for a reasonably priced installation, having a low maintenance and operating cost. It is feasible to make the system in small or moderate sized units and include automatic features as additional conveniences. M M p The partial vacuuminduced by the exhaust pump, in conjunction with a suitable regulating valve is employed to give a balancing effect in the cooling results. This arrangement avoids the apparatus required in a conventional refrigerated system and its expensive sundries. The recirculating coil employed in this invention is an advantageous feature in that it stretches the temperature limits over a considerable range. This unit can be utilized in cold and warm climates. This invention em phasizes in its operation: (1) a vacuum eifect on the treated air; (2) control of the amount and pressure of the entering air by a regulating valve; (3) a heat interchanger coil for varying the cooling action; (4) and a humidity control for the dispersed air and (5) a panel for creating a bubbling system of streams through water, evenly and fully distributed for producing a humidifying, cooling and. moisture saturation effect; (6) a comparatively noiseless action.
For a better understanding of the invention and the objects thereof, reference is made to the accompanying drawings, wherein a preferred form ofthe invention: is indicated. These drawings in conjunction with the following description, illustrate the invention; explain its principles and explain its method of operation.
Referring to the drawings:
Figure 1 is a sectional elevation taken longitudinally throughan air tempering unit on line 1-1 of Figure 2, together with its connections, and embodying this invention;
Figure 2 is a" transverse sectional elevation taken" on line 2--2 of Figure 1'; and
Figure 3 is a View in perspective of the filtering and air distributing panel used in this embodiment.
Similar reference characters refer to the same parts throughout the drawings: v M
In the construction shown in the drawings, a cabinet 10' of formal rectangular contour and suitable material, thickness, and strength is" provided to contain the various items that make up the equipment of an air tempering unit. The interior of the cabinet includes an air ing and coil section" 12, perforated baffles and drip plates 21 and 22, and an upper secondary. chamber 14, for holding the tempered airready for disp'rs'al.'
The chamber 11 is separated and partitioned on from the section; 12 by a relatively thin perforated anel 15. Its perforations 16 are evenly distributed over the panel 15, and are made very minute. I The perforations are small eaougnto avoid leakage (because of surface tension) of appreciable quantities of water resting on the panel 15. The chamber is fed with air under pressure through a piping inlet connection 17 and after accumulating in the chamberapassels it in' fine needle-size streams through the holes 16, into the water section 1 2'. The air continues through the water 18 and fills the space 20 above the latter. 4 Then a suction or vacuum device, pump or exhaus'tfan 1 9 rriounted on outer top rf 'l of the c bi et a a d q de la pe t a vacuum in the sp'aceQll induces the air to flow out f h a e t n id ab e t fii i up h heat to reduce its temperature a cor'isiderable number of degrees. As the airleaves the space, it passes w n a s o bfliam ri pl ll W 2 .11 lower baflie 22 has perforations 23 to allow any egicelss water. condensing outpfthe air, to accumulate on ita'nd drip back into the water 18 below. The device 19 is driven r m tor 0 The baffle plates are placed relatively close to cine atiother and serve to squeeze or comprejss the air stream as itpasses to the upper chamber 1 4 for the tempered air. From the upper chamber 14 the air passes through main outlet piping connection 24 to the. suction devige. pump or exhaust fan 19 and is discharged intothe piping 25 The piping carries the air to a diversion valve 2 6 of the three way type. The valve 25 canbeoperated to send the air into mann r 27 from a pipeline 28 connected to it. At the outlet, the air is distributed i nto a room (not shown) intended to be supplied by it and cooled; If the valve 26 is operated in another direction it diverts the air through the piping connection 29 at the water pool in section '12. The air continues through into a tubular copper coil 30 which is cooled further by the water 18; already cooled by the evaporative action of the air passing through it under pressure and ,vacuum.
