JAMES POSEY, OF BALTIMORE, MARYLAND, ASSIGNOB TO THE TWO-SEASON PROCESS, INC., OF NORFOLK, VIRGINIA, A CORPORATION OF VIRGINIA.

COMBINED HEATING AND COOLING APPARATUS.

Application filed August 1, 1928. Serial No. 296,689.

My invention relates to apparatus for regulating the temperature within a building or the like, by introducing air therein, at a suitable temperature.

In accordance with my invention, air under suitable pressure is forced through air circulating tubes, through Which extend inner tubes, for receiving the temperature regulating fluid. The apparatus is so constructed that an eflicient heat exchange is effected between the temperature regulating fluid and the air, and a relatively large volume of air is adapted to be handled by the apparatus. The apparatus is of simplified construction, and is cheap to manufacture. The apparatus may be employed to heat the air or to cool the same.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a central vertical longitudinal section through heat exchange apparatus embodying my invention,

Figure 2 is a horizontal section taken on line 22 of Figure 1,

Figure 3 is a front end elevation of the apparatus, and,

Figure 4 is a transverse section taken on W line 44 of Figure 1.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral 5 designates a preferably cylindrical casing, which is preferably horizontally arranged. This casing has its rear end closed by a head 6 and its front end closed by a head 7, having gastight joints therewith. Arranged within the rear end portion of the casing 5 are spaced 49 transverse heads or

plates

8 and 9, providing rear and forward transverse drums 10 and 11, as shown. The

heads

8 and 9 are rigidly connected with the casing 5, and form gastight joints therewith.

Arran ed between the inner head 9 and the forward ead 7 is a horizontal partition 12, rigidl secured thereto and with the casing 5, and orming a gas-tight joint therewith. The artition '12 with the associated elements, divi es the casing 5 into an upper horizontal lon itudinal compartment 13 and a lower horizontal longitudinal compartment 14, and these compartments are semi-cylindrical.

Disposed within the upper longitudinal compartment 13, near the forward head 7,

is a transverse head or plate 15, which is semicylindrical, and is rigidly attached to the partition 12, and the casing 5 to form a gas-tight oint therewith. The transverse partition 15 with the associated elements, provides within the upper longitudinal compartment 13, an air discharging chamber 16, and a products of combustion discharge chamber 17. The chamber 16 is provided with an outlet connection 18, adapted to have communication with an outlet ipe which will lead to the registers or the li e in the room. The roducts of combustion discharge chamber 1 has'an outlet connection 19, ada ted for communication with a suitable stac or pi e.

Arranged within the lower lbngitudinal compartment 14 is a semi-cylindrical transverse vertical partition 20, rigidly attached to the partition 12 and to the casing 5 and forming therewith a gas-tight joint. This partition, with the associated elements, provides a rear air intake chamber 21 and a forward temperature regulating chamber 22, as shown.

Extendin longitudinally within the air discharge 0 amber 16, are air circulating tubes 23, the rear ends of which are held within openings 24, formed in the head 9. The tubes 23 have their rear ends in com-' munication with the interior of the drum 11. The forward ends of the tubes 23 are spaced from the head 15, and dischar e directly into the forward portion of the e amber 16. The forwardends of the tubes 23 are su ported by transverse angle irons 25 rigidl attached to the casing 15. Extending longitudinally through the air circulating tubes 23 in spaced concentric relation thereto, are temperature regulating or heating tubes 25, the rear ends of which are held wlthin openings 26, formed in the head 8, and these rear ends are in communication with the drum 10. The forward ends of the heating or temperature regulating tubes 25 are held within openings 27, formed in the head 15, and dis charge into the drum- 17.

Extending longitudinally within the air inlet chamber 21 are air circulating tubes 28, the rear ends of which are held within openings 29, formed in the head 9, and these rear ends are accordingly in communication with the drum 11. The forward ends of the tubes 18 are spacedfrom the head 20, and are, therefore, in free communication with the chamber 21. Extending longitudinally 20, and are, therefore, in communication with through air circulating tubes 28 are heating or temperature regulating tubes 30, the rear ends of which are held within openings 31 formed in the head 8 and lead into the drum 10. The forward ends of the tubes 30 are held within openings 32, formed in the head 22. The burner 37 receives gas through a pipe 38, passing through an opening in the cover 36, and in a pivoted valve plate 39. The cover 36 may also be provided with air feedmg openings 40, adapted to bemoved into'and out of registration with openings 41 in the valve plate 39. It is obvious that by turning the valve plate 39, the openings 40 may be wholly 'or partly covered or uncovered.

Instead of employing a source of heat 37, I may employ a refrigerating unit 42. When this is done, the burner is removed, and an imperforate plate similar to the plate 39, is substituted for the plate 39.

The numeral 43 designates a brine pipe, leading into the drum 10, and equipped with a valve 44.

1 The operation of the apparatus isas folows:

The burner 37 being set in operation, heated gases and products of combustion pass through the innertubes 30, traveling rearwardly, and discharging into the rear drum 10 and then passing upwardly and discharging into the tubes 25. The heated gases pass forwardly through these tubes and enter the drum 17, and then discharge to the stack. The rotary blower or fan 34 being now in operation, air under suitable pressure is fed into the air in take chamber 21 and enters the air circulatmg tubes 28 to travel rearwardly therein and enter the drum 11. The air then passes upwardly in the drum 11, and enters the rear ends of the air circulating tubes 23 traveling forwardly therein and discharging into the forward end of the air outlet chamber 16, from which it passes through the connection 18 to the desired register or registers.

1le passing through the air circulating tubes, the air is made to travel in close relad tion to the heating tubes, and surrounds these tubes. In this way an efficient heat exchange is effected between the products of combustion and the air. The volume of air which may be passed through the apparatus is relatively arge.

When the apparatus is used to cool the air, the burner 37 is removed and the refrigerating unit 42 is introduced into the chamber 22. The valve 44 may now be opened and brine supplied thereto into the drum 10, such brme filling the

tubes

25 and 30 and also filling the drums 10 and 17 up to the elevation of the top tube 25 and also filling chamber 22. The air is forced through the air circulating tubes in a similar manner, and is chilled by passing about the temperature regulating tubes.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that various changes in the shape size and arrangement of parts, may be resorted to without departing from the s irit of my invention, or the scope of the subjoined claims.
