5 Claims.. (01. 237-8) This is a division of my original application Serial No. 247,696 filed January 18, 1928, for Letters Patent of the United States for Improvement.
in methods of heating and ventilating.
,Structures hereinafter described including a.
radiator, a fan, and a motor therefor, in combination with a casing, are the subject matter of my copending divisional application for Letters Patent of the United States for Improvement in heat exchange apparatus, Serial No. 412,972 filed December 10, 1929.
My invention relates to heating systemsinclu'ding a furnace comprising a fuel burner in cooperative relation with a container in which any suitable heating fluid, for instance, steam or water, may be heated; and conduits forming a circulatory system leading from and returning to said container and supplying said heating fluid to a radiator or radiators, to heat the atmosphere local to the radiator surface. The purpose and effect of my invention are to facilitate and augment the transfer of heat from the radiator surface to the adjacent atmosphere by more rapid displacement of the air at such surface than is possible by convection; and at a rate variable with the heat supplied.
As hereinafter described, my invention includes means for facilitating and augmenting the transfer of heat from a fluid supplied to a radiator to the atmosphere adjacent to the radiator, by utilizing power from the heating fluid to operate a motor to forcibly circulate the air relatively to the radiator, by means of a rotary fan. 1
The typical heating system herein disclosed includes a gas burning water heater ,and means for maintaining a forced circulation of water within the heating system, by an electrically controlled pump; the operation of the device being controlled by thermostatically operative means; and theforced circulation of air thru the radiator is effected by a motor included in a bypass shortcircuiting the radiator with which it is associated; so that theheating fluid is taken into the motor from the supply conduit leading from the heater to the radiator, and the exhaust from the motor is discharged into the return pipe leading from the radiator back to the heater.
My invention herein claimed includes the various novel features of construction and arrange-.
L a house heating system embodying my invention.
Fig. II is a'vertical sectional view of one of the radiator structures shown the line II, II.
Fig. III is a plan sectional view of said structure, taken on the line III, III in Figs. I and II. Fig. IV is a fragmentary sectional view of the fluid motor indicated in Figs. I and II.
in Fig. 1, taken on Fig. V is a fragmentary sectional view of a modified form of fluid motor.
Referring to Fig. I; the house or other building comprising rooms or other inclosures 2. and 3, has, preferably in the cellar 4 thereof, the heater 6 inclosing the burners '7 and 8 supplied with gas from the conduit 9 under control of the thermostatically operative valve in the casing 10. Said valve casing carries the tubular thermostatic element 11 extending within the water conduit 12 which is connected with the pipe 14 thru which hot water is-delivered from the cel-- lular heater units 16 which are supplied with cold water thru the pipe 18. Said conduit 12 is connected by pipes 20 with radiator units 21, from which the water is returned thru pipes 23 to the pump 24 which is connected to said pipe 18 and arranged to be operated by the electric motor 25, under control of the thermostatically operative switches 27. Said pump is operated to circulate the water thru the system in the direction indicated by the arrows.
Referring to Figs. II, III and IV; each of said radiators 21 comprises a cellular structure 30 which is a rectangular congeries of metal tubes 31 having enlarged polygonal ends 32 which fit together and are sealed in connection with a casing band 33 so as to form a cellular honeycomb of thin metal walls and comprising separate pas sageways 35 for hot water or steam and 36 for atmospheric air. Said radiator includes the inlet port 38 and the outlet port 39 in communication with said passageways 35 for the heating medium. The outer casing 40 for said congeries 31- forms a cold air inlet chamber 41 at the bottom thereof, an intermediate chamber 42 containing said cellular structure, and an upper outlet chamber 43 for the heated air. The fluid motor 45 is preferably mounted in said inlet chamber 41 with a fan 46 arranged to force air into said outer casing 40 thru the stationary louvers 47 in the lower portion of said casing and thru the passageways 36 in said congeries of tubes, and out from the heated air chamber 43 into the surrounding atmosphere, thru the foraminous panel'or grill 49.
Said fluid motor 45 includes an outer casing 50 provided with ports 51 and 52 thru which the heating fluid in the system circulates from the pipes 20 to the pipes 23. Said casing 50 contains the rotor 54, the blade 55, and the shaft 56, which latter is journaled in said casing and in operative connection with said fan 46. Valves 57 and 58 may be provided local to said motor casing to vary the relative volume of the heating fluid which shall be directed to the radiator 21 and thru the motor 45. It is to be understood that said valves may be adjusted to variably determine the speed of rotation of the motor and consequent air displacement effect of said fan 46 to attain the desired efliciency of transfer of heat from the radiator to the surrounding atmosphere; it being noted that such capacity should be increasedand diminished in accordance with increase and decrease in the heat supplied to the radiator. Altho said fan 46 is indicated as in coaxial relation with said shaft 56, it is to be 'wheel 61 may be connected by a belt 62 with a pulley 63 on the shaft 65 which carries the fan 46. Said motor 59 may be included in multiple relation with a radiator 21 in a bypass from the supply pipe. 20 to the exhaust return pipe 23 and be controlled by valves 57 and 58 as above described; but may be otherwise exhausted.
Therefore, I do not desire to limit myself to the precise details of construction, arrangement,
or procedure herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
