arnponmrron'me SYSTEM.

Application filed May 1,

My invention relates to improvements in iir conditioning systems for houses, ships and like structures, wherein perishable commodities are stored for greater and less periods '5 of time.

An object of the invention is to provide a system for effectively refrigerating and ven tilating the chambers of structures of the character above noted, said system embodying elements constructed and arranged, not

only to set up a thorough convective and diffused ventilated circulation of air within a chamber or chambers to which the system is applied, but also to provide for the maxi- 1 mum space for storage and for maximum facility in the handling of commodities within said space.

Another object of the invention is to supply a system, as above described, which is adapted to provide for the heating of a structure and as under refrigeration, to ventilate the structure as well.

More specifically, it is an object of the invention to employ a space along the floor of a chamber supplied, in part, to accommodate air conduits, also to use similar spaces along the sidewalls of the chamber, in conjunction With said space along the floor, for passageways serving to distribute air to the interior of the chamber, and further to provide means apart from the chamber proper for circulating air in the chamber through said conduits and passageways, and for changing the temperature of said air and freshening the same. With the foregoing and other objects-in View, which will appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

In the drawings, Fig. 1 is a vertical, longitudinal, sectional viewof a building shown as equipped with an air conditioning system embodying my invention, said view being taken as on the lines 11 of Figs. 2 and 3,

A parts of the sleepers, floor and side slats being broken away; Fig. 2 is a vertical sectional view taken transversely of the building as on the line 2-2 of Fig. 1; Fig. 3 is a fragmentary view similar to Fig. 2, the same being taken on the line-3 3 of Fig. 1, and Fig. 4 is a detail plan view of the coil chamber and fan room structure surmounting the building, the roof of said structure being removed. Reference being had to the accompanying 1926. Serial No. 106,145.

drawings, it will be observed that the building shown includes the usual sidewalls 10, end walls 11 and 12', main floors 13, and roof H, wherein provision chambers are pro vided. Extending transversely of each main floor 13 are two series of sleepers 15, one series at one side of a medial longitudinal area of the floor and the other series at the opposite side thereof. Nailed across these sleepers 15 of each chamber and extending longitudinally of the building are spaced floor slats 16 constituting a false floor. In each chamber riser timbers 17 rest at their lower ends upon the outer extremities of the sleepers 15, said riser timbers extending upward along the main sidewalls 10 to the ceiling of the chamber. Across these timbers 17, wall slats 18 are secured, the same comprising false sidewalls forming air passageways B, at the sides of the chamber, which passageways communicate with the air passageway C formed between the. floor slats 16 and the main floor 13.

At the center of the roof 14 of this building is a structure comprising an elongated housing 19, thesame being provided with a transverse partition 20, dividing the interior of the housing into a compartment D and a room E. In the compartment D 'are staggered tiers of coils 21, through which any suitable temperature affecting medium may be conducted. A horizontal pipe 22 passing through the partition 20 brings the compartment D and room E into communication one with the other, a fan 23 within the room being placed adjacent to the open end of said pipe in said room.

Passing downward through the roof 14 of the building from the lower portion of the compartment D, at the outer end thereof, is a duct or main 2 4, which extends along the middle of the .ceiling of the uppermost chamber A to the inside of the endv wall 11 of the building. This main 24 thence extends downward through intervening floors 13 to the floor 13 of the lowern1ost chamber included in the system. Upon the floor 13 of each of "such chambers A and extending through the medial space left between the inner ends. of the sleepers 15 area pair of spaced conduits 25, each conduit of the pair communicating atone end with said main 24 and being closed at the other end thereof. The outer side of each conduit25 is slotted longitudinally thereof as at 26, which provislon brings one conduit 25 into cornmuni cation, throughout its length, with the floor passageway C at one; side of the middle of the chamber and likewise brings the other conduit into communication with. said pas- A second uprlght main 27 is employed E of the housing 19. On. the floor 13 of each along the inside of the endwall 12 medially thereof, said main extending upward from the floor 13 of the lowermost chamber A,

through intermediate floors 13 to the ceiling of the uppermost chamber, thence along said ceiling toward the center thereof, thence upward through the roof 14 of the building and thence into the upper portion of the fan room chamber A and between the spaced conduits 25 therein, is a conduit 28 formed at its upper side witha slot 29 extending longitudinally thereof. Each of these conduits 28 communicates at one end thereof with the main 27, the other end being closed.

Produce for storage within a given chamber A is readily trucked over the false floor formed by the floor slats 16, and over the

conduits

25 and 28, foot lates (not shown) or other conduit protecting means being employed in the event that the conduits them selves are so constructed as to be unable to withstandan appreciable weight. The, produce is stacked in tiers stopping short'of the ceiling of the chamber and spaced. apart from the wall slats 1'8 and above the slot 29 in. the conduit 28. ,7 When it is desired to refrigerate the stored produce, a refrigerating medium is conveyed through the'coils 21 in the compartment D of the housing 19 and to augment the chilling effect of such medium in said coils, tiers thereof, indicated at 21 (Fig. 4) are permitted toffrost over to form bafile walls for directing air in a circuitous path in its passage through said compartment. The fan 23 is driven by a fan motor 30 in direction blowing into the pipe 22. Thus driven, said fan withdraws.

air, through the fan room E, from the main 27 and the conduits 28 connected therewith and forces such air into the coil compartment D, through the main 24 and into the conduits 25 connected therewith. In passing through the coil compartment D, theair is chilled and n this condition is forced outwardly through the slots 26 in the conduits 25. Entering the passageways C underthe false floor slats 16, a part of the chilled air filters upward between the slats 16 about the lading on the false floor, the remainder thereof being urged into the side passageway B, where it is aided in its ascent along the relatively warm sidewalls. 10 and froinwhich side passageways said air "filters through the side slats 18 into the lading space. In opposition to the ressure built up toward the sidewalls o the building through the egress of air from flie conduits 25 is the suction-caused by the fan 23 at the slots 29 in the conduits 28. This suc- !circulation of chilled air is setup within the. chambers A, suchcirculation being augmented under the natural laws at the sides of said chambers.

When it is desired to heat the produce stored within the chambers A, steam or other heating medium is conducted through the coils 21 in thecoil compartment D and the rotation of the fan 23 reversed so that it will draw air through the pipe 22. Thus rotating the fan draws air from the coil compartment D wherein said air is heated, thence it forces said heated air from the fan room E through the main 27 to the conduits 28 and upwardly out of the slots 29 therein. Said fan 23 also draws air from the floor passageways G into the conduits 25, through the main 24, thence back into said coil compartment D. The heated air rising naturally from the conduits 28 and augmented by the force of the fan 23 asoends through the space left between the stacked produce. Thence spreading' along the ceilings of the chambers A and descending by gravity between the produce containers said air, now more or less cooled, is urged downward through the false floors and drawn along the floor passageways G into the conduits25 by the sucking action of the fan 23. In this connection, attention is invited to the fact that the air in the side passageways B' along the relatively cold side walls 10 has the natural tendency to fall by gravity taking air into the descending streams between the side slats 18. These descending streams of air upon entering into the floor passageways C are forcefully affected by the suction at the slots 26 in the conduits 25 in said passageways C. Thus, it will be understood that, under heating as well as under refrigeration, a thorough connective and diffused circulation of air is set up within the chambers A. In the fan room E is an upright pipe 31 extending from a point near the floor to a point near the ceiling, said pipe'being fitted with a horizontal branch 32 opening through one side of the housing 19 and further fitted with a damper 33 near its upper end and with a damper 34 near the lower end thereof. Within the coil compartment D is a similar upright pipe 35, similarly fitted with abranch 36 and dampers employing the system for refri poses, the circulatin air may to ventilate the cham crating pure ffeshened 37 and 38. When ers A by admit'ting air, 1 under the suction of fan 23, into the'fan air may be ading passa frigeration, theair in the system is too low in percentage of humidity with the

dampers

33 and 37 open, the condition may be corrected by closing said dampers and opening the dampers 3t and 38. Under this adjustment of dampers warm air from the outside is admitted into the lower part of the fan room E under the inflowing colder air with the result that the humidity is increased. Further. the direct air in the lower part of the coil compartment D is removed there from. Accordingly, to meet other circumstances the

dampers

34, 35, 37 and 38 are appropriately adjusted.
