WALDER, 0F MINNEAIYOLIS, MINNESOTA HEATING AND VENTILATING SYSTEM Application led October 25,- 1926. Serial No. 143,895.

This invention relates to heating and ventilating systems and more particularly to such systems of the indirect type.

It is the main object of the invention to provide a simple and highly efficient indirect heating, cooling and ventilation system capable of being easily installed in connection with a steam or hot water boiler.

This and other objects of the invention will be apparent from the following description made in connection with the accompanying drawing wherein like characters refer to similar parts throughout the several views,

' andin which Fig. l is a diagrammatical view, showing a preferred embodiment ofmy invention installed in a building;

Fig. 2 is an end elevation, showng the fan with some portions broken away to show the distributing conduits and dampers; and

Fig. 3 is a cross section taken on the line Referring to the drawings, in detail, a steam boiler A is illustrated supported 011 the basement floor B, a Wall of the'buildin-g being indicated by the letter C. D indicates-thel first floor of the buildingv supported on the joists E.

I- provide a relatively large heating chamber4,preferably formed of sheet metal having tapered front and rear ends 4a and 4b respectively. Themain air intake passage 5 communicates with the rear tapered end 4b, draw-- ing its supply of air preferably from the interior of the building and controlled by means of a damper 6. The forward tapered end 4EL of the heating chamber is connected to a fan 7, driven through endless belt 8 by means of a motor 9, illustrated as mounted on a base 10 supported by floor B. The outlet of the fan casing is divided into a plurality of compartments, best shown in Fig. 3, communicating with the distributing conduits lland- 12. As illustrated, the outlet -passage of tlie fan is divided longitudinally by a partition 13 and transversely by partitions 14, forming two relatively large passages 15 communieating with the distributing conduits and three smaller passages 16. Inwardly swinging dampers 17 and 18 are mounted in passages 15 and 16 respectively, controlling the admission of air therethrough. These dampers are hinged lto the walls of the fan casing, outlet dampers 17 and 18 swinging oppositely and stopped 4by means of vertical parti- 55 tion 13, as shown in Fig. 2. Thehinges of said dampers are disposed below the lower edge of partition 13 to cause said dampers to be diagonally disposed when closed. Damper bars 19'extend through the sides of 00 the fan outlet. v

Chamber 4 and fan 7 are supported by any suitable means, such as the horizontal platform 20, supported from the joists E, by means ofhoo'k bolts 21. 65

A relatively small air intake conduit 22 communicates with the tapered rear end 4b of chamberv 4 at a point below passage 5 and is provided with the damper 23 to control the admission of air therethrough. Conduit 22 70- draws air from without the building for` the purpose of supplying, if desired, to the circu-` lation a small amount of fresh air.

Within the central portion of chamber 4, I mount a' radiator 24 of any suitable type, 75 connected to boiler A, by means of intake and Aoutlet pipes 25 and 26 respectively. An atomizer or distributing valve 27 is provided in the forward end of radiator 24 preferably disposed centrally of the last coilor unit and adapted to discharge vaporwithinthe heating chamber, A support 28 is disposed be-v tween radiator 24 and fan 7, within chamber 4, adapted to support a refrigerating coil 29. A-suitable door 30 is provided in one side of 85 chamber 4 topermit coil v29 to be removed in cold weather if so desired.

Opera-taba l turefdischarged may tributing conduits.

The construction of the passages 15 and 16 communicating with distributing conduits 11 and 12 and the mounting of dampers 17 and 18 is of considerable importance. It will be seen that t-he dampers when closed serve to direct the heated and moistened air to the open passages, because of their diagonal disposition and the fact that they are hinged to the sides of the fan discharge.

In warm weather the refrigerating coil 29 may be operatively connected to a refrigerating lant and the apparatus will serve as a cooling system for the building. It will be seen that the building is not only heated by means of the indirect system, but is, moreover, eliciently ventilated thereby.

The efficiency of the system is high, due to the fact that the air is circulated through-- out the building and will be readily re-heated or cooled to the desired temperature by passing through the thermo chamber 4. The proper humidity may be maintained in the circulating air without requiring humidifiers in the several rooms within the building.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of parts without departing from the scope of the invention.

What is claimed is:

1. Apparatus yof the class described having in combination an elongated chamber, an air intake passage adjacent one end of said chamber, means for causing air to pass through said chamber, means for thermally treating air passing through said chamber, and heat distributing means comprising a pair of oppositely disposed passages, oppositely swingable dampers in said passages ada ted to form in conjunction a concavo sur ace when closed, and each operative to guide discharged air to one of said passages when the damper in said last mentioned passage is open.

2. Apparatus of the class described having in combination an elongated thermal chamber, an air intake passage adjacent one end thereof, means for causm air to pass through said chamber, means or thermally treating said air in its passage and heat d1s tribu'ting means adjacent the other end of said chamber comprising a air of oppositely swingable plates hing at their outer ends and disposed when closed in oppositely inclined positions, with -their free ends in juxtaposition, whereby when one of said plates is opened and said other plate closed said closed plate will guide discharged air.

through the passage controlled by said open plate.

-3. In air conditioning apparatus, an elongated chamber. having an air intake passage adjacent the rear end thereof, and a discharge passage adjacent the forward end thereof, a radiator element within said chamber connected-to a source of hot circulating iuid, a discharge passagel at the forward -end of said radiator element, a humidifying valve'connected with said'last named discharge passage and constructed to dispense a conical discharge of uidcentrally of said chamber and in the direction of said discharge end, a suction fan at the discharge vend of said chamber adapted to set up a swift passage of air therethrough andto mix with said air and disintegrate particles of fluid dis,- pensed by said humidifying valve, andan air deliver conduit connected with the delivery end o said fan.

4. Air conditioning apparatus built in the form of a unit, comprising an elongated sube stantially straight casing having an airI intake passage adjacent its rear end, and an air discharge passage adjacent its forward end, means for suspending said casing from the joists of a oor, a radiatorelement mounted within and supported from said casing and connected with a source of hot circulating fluid, a discharge passage at the forward end of said radiator element, a humidif ing valve connected with said last named ischarge passage and constructed to dispense fluid centrally of said casing and in -the direction of the discharge end thereof, and a suction fan secured to the forward end of said casing and adapted to set up a swift passage of air through said casing and also to mix with said air and disintegrate particles of fluid dispensed by said humidifying valve, and an air delivery conduit connected with the discharge end of said fan.

In testimony whereof I afiix my signature.
