Application filed Kay 1,
My invention relates to'improvements in refrigerating and air circulating systems for cold storage and other chambers.
An object of the invention is to provide a system of the present nature that is simple and inexpensive, the parts whereof are conveniently arranged to set up a convective and difi'used circulation of air in a. chamber by gravity, and the same being adapted to refrigerate said circulating air effectively to the end that extremely low temperatures may be maintained in all parts of the chamber.
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 sectional view illustrating a storage chamber in a building structure and showing in transverse section various. of the elements included in a system embodying my present invent-ion; Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1 and Fig. 3 is a similar view taken on the line 33 of Fig. 2.
Reference being had to the accompanying drawing, it will be seen that the illustrated embodiment of my invention. portrayed in Fig. 1 is shown as applied to a chamber A formed between a floor 10. sidewalls 11 endwalls 12 and ceiling 13 of a building structure. Short hanger bolts 14; depending from the ceiling 13 carry a number of main string ers 15 ofangle iron, said stringers traversing the chamber proper. Hanger straps 16 depending from said stringers 15 are each fitted with pipe embracing clips 17. The assembly comprised by said hanger straps 16 extends medially and longitudinally of the chamber A. correspondingly disposed is a relatively deep assembly of pipes 18. each bent to provide banked reaches said assembly extending from end-to-end of the chamber and comprising two groups. substantially spaced apart to form a port 13 theiebetween. The upper reaches of the pipes 18 rest upon the stringers 15. while each of the lower reaches of said pipes 18 is caught by one of the clips 17 carried by a hanger strap 16. Short hanger bolts 19 depending from the main stringers 15 support two sets of sub-stringers 20 of angle iron, each set of sub-stringers being disposed between the deep asembly of pipes 18 and 1926. Serial 1T0. 106,148.
one of the said walls 11 of the chamber A. Associated with each set of sub-stringers 20 is a relatively shallow assembly of pipes 21. each pipe having an upper reach supported upon the main stringers 15 and a lower reach supported on sub-stringers 20. Each shallow assembly of pipes 21 extends laterally of the chamber A from the deep assembly of pipes 18 to a line near the adjacent side wall 11. leaving a port- C between the outer extremity of said assembly and said sidewall. Paralleling one endwa-ll 12 of the chamber A. is a main D consisting of T-fittings 22 joined by nipples 23, each of the upper reaches of the pipes 18 and 21 being threaded into a companion T-fitting 22. A similar main E comprises T-fittings 21 and nipples 25, the lower reach of each pipe 21 being threaded into one of said T-fittings 24 and the lower reach of each pipe 18 connected with one of said T-fittings 24 through a branch pipe 26. One of the mains D and E serves to feed a refrigerant to the pipes 18 and 21 and the other to return said refrigerant to the source of supply.
Lading is stacked on the floor 10 beneath the pipes 21 an isle being left clear of lading beneath pipes 18. Any suitable refrigerant is conveyed to and from the pipes 18 and 21 through the medium of the mains D and E. The refrigerant. in passing through the pipe 18 and 21. effects a reduction in the temperature of the air about said pipes with the result that aconvective and diffused circulation of air is set up in the chamber A by gravity. The relatively great cooling effectupon the air at the deep assembly of pipes 18 causes a relatively strong down flow of air medially of the chamber A with the result that a main flow of air isinstituted in the direction of the arrows in Fig. 1, the descending air mediallv of the room reaching and following the floor toward the side walls 11, thence rising along side relatively warm sidewalls through the ports C. and then returning to said deep assembly of pipes 18 along the ceiling 13 of the chamber. Accompanying this marked convective movement of air within the chamber is the lesser diffused flow of air set up by the presence of the refrigerant in pipes 21. Descending from said pipes 21, the cooled air drops about the lading therebeneath, then rises again and upon being heated by the lading. This lemer move ment of air, though not having the definite form baflie Walls of ice. This-practice increases the main flow of air within the chamber, the provision of port B between the two groups of pipes 18 furnishing greater freedom of movement of the air through the deep assembly of pipes 18 than would beafforded alone between the relatively closely related banked reaches of said pipes.
a The upper reach of each pipe 18 is fitted with a cut-off valve 28, the lower reach thereof being provided with a similar valve 29. Likewise the upper reach of each pipe 21 is supplied with a cut-ofi valve 30, the lower reach thereof being furnished with a similar valve 31.. By the adjustment of these valves the pipes 18 'in the deep assembly and thepipes 21 in the shallow assemblies may be selected for the conveyance therethrough of the refrigerating medium employed. 1
Changes in the specific form of my invention, as herein disclosed, may be made withinthe scope of what is claimed without de-' parting-from the spirit of my invention.
' Having described my invention, What I claim as new and desire to protect by Letters Patent is: r e
1. The combination with a chamber, of main stringers hung from the ceiling and traversing said chamber, an assembly of hangers depending from said .main stringer in arrangement medially and longitudinally of the chamber, a relatively deep assembly of banked reaches of pipe, the upper reaches of said banks being supported on said main stringer, the lower reaches thereof being supported b said hangers, sub-stringers hung from tile main stringer at either side of said pipe assembly, a relatively shallow assembly of banked reaches of pipe at either side ofythe deep assembly, each shallow assembly including upper reaches of pipe supported by said mam stringer andlower reaches of pipe supported by said sub stringers, each shallow assembly of pipes falling short at its outer extremity of the adjacent side wallof the chamber, and means for conducting a refrigerant to and from said pipe assemblies.
2. The combination with a chamber, of supporting means therein, a system of banked reaches of pipe carried by said sup porting means and adjacently underlying the ceiling of said chamber, said system including a relatively deep assembly of pipes extending medially of the chamber from end to endthereof and arranged to provide a vertical central port in said deep assembly, said system also including two relatively shallow assemblies of pipes, one at one side of said dee assembly and one' at the other side thereo each shallow assembly of pipes stopping short at its outer extremity of the sidewall of the chamber toprovide a side port and means for conveying a refrigerant to and from said pipes. l
'3. The combination with a chamber, of supporting means therein, a system of refrigerant conducting pipes, carried by said supporting means and adjacently underlying the ceiling of said chamber, said system including a relatively deep assembly of pipes extending. medially of the chamber from end to end thereof and also .including two relatively shallow assemblies of pipes, one at one side of said first mentioned assembly and one at the opposite side thereof, each shallow assembly stopping short at its outer extremity of the adjacent sidewall of the chamber, and means for conveying a refrigerant to and from said system of pipes.
4. The combination with a chamber, of supporting means therein, a system of refrigerant conducting pipes carried by said supporting means and adjacently underlying the ceiling of said chamber, said sys-.
tem including a relatively deep assembly of pipes extending medially of, the chamber and also including two relatively shallow assemblies of pipes, one at either side of said deep assembly, an inlet header common tothe entire system of pipes and an outlet header also common thereto.
In testimony whereof, I have signed my name to this specification.
CHARLES Al MOORE.
