Description
REFRIGERATION SYSTEM Filed March 30, 1935 Patented Aug. l0, 1937 PATENT y OFFICE REFRIGERATION SYSTEM William J. Barbers, Philadelphia. Pa., assignor to American Engineering Company, Philadelphia, Pa., a. corporation of Pennsylvania Application March 30, 1935, Serial No. 13,843
1 Claim.
This invention relates to refrigeration apparatus, and more particularly to the refrigerating coils associated with such apparatus.
Eiiicient refrigeration of a chamber depends primarily upon two factors; first, proper circulation of the air in the chamber, and second, upon the arrangement of the cooling coils so that the maximum amount of air will come into direct contact therewith. In many installations certain obstructions to the flow of air, such as drip pans or gutters, are necessary to prevent damage to the food or other products placed in the refrigerated chamber from the accumulated moisture dripping 5 from the refrigerating coils. These obstructions, in some cases, interfere with the circulation of the air in the chamber to such an extent that the etliciency of the unit is .greatly impaired.
One object of this invention is to reduce to a minimum the size of such necessary obstructions,
and thereby obtain maximum eiciencies under 35 Fig. 2 is a side view of a nned coil and the drip gutter associated therewith.
Fig. 3 is an end view of the bank of nned coils shown in Fig. l.
Fig. 4 is a side view of a somewhat modified 40 construction. Fig. 5 is an end view taken along line 5 5 of Fig. 4, and
Fig. 6 is an end view of a further modification. Referring to the drawing, the numeral I designates generally a refrigerated chamber having the usual insulated end and side walls 2 and 3 respectively. The floor 4 and ceiling 5 of chamber l are also constructed of insulating material. A door 6 provided in one of the side walls 3 is 50 also constructed of heavy insulating material of any suitable type.
Mounted near the top of chamber I and extending substantially the entire length thereof is a bank of finned refrigerating coils 1. This bank 55 of coils rests upon a pair of spaced cross bars 8 which are suspended from the ceiling 5 by rods 9 secured to the ceiling in any suitable manner, such as by nuts III engaging the upper threaded ends II thereof.
Each coil l comprises a tubular portionl I2 through which the refrigerant is circulated, and a series of transverse substantially rectangular ns I3 secured thereto. The ns I3 are pressed tightly into intimate thermal contact with the tubes I2 and consequently the fins, as well as the tubes, are maintained relatively cold by the circulation of the refrigerant. Thus the air coming in contact with the fins is also effectively chilled.
As shown in Figs. l and 3, suitable piping I4 extends from the opposite ends of each coil, and to facilitate the connection of several coils together into banks, couplings I5 are provided in the piping between adjacent sections. In the present instance the coils 1 are connected in series, the refrigerant entering the coils through a pipe I6 and owing in the direction of the arrows in Fig. 1 and discharging to a condenser (not shown) through a pipe I'l. As shown more particularly in Figs. 1 and 3, the coil sections 1 are supported on edge. This not only produces a greater spread of the fins, thereby increasing the efficiency of the unit, but enables the use of relatively narrow drip pans or gutters I8, because of the adhesion of the moisture to the fins. the moisture runs to the lowermost corners I9 of the fins before dripping therefrom due to its own weight.
The drip pans or gutters I8 are suspended from cross bars 8 in any suitable manner, such as by straps 20, and are arranged slightly below the lower edge I9 of the coils. These gutters therefore offer little interference to the circulation of the air around the coils. As shown in Fig. 2, the drip gutters I8 incline slightly from the horizontal, the lower ends of which communicate with a second gutter 2l extending transversely of the chamber I. Gutter 2l is supported by brackets 22 secured to and depending from one end of the end sections "I, as shown in Figs. 2 and 3. 'Ihe moisture discharging into gutter 2| from gutters I8 is conducted to the main drain through a spout 23 communicating with the lower end of said gutter 2|.
As a result.
Figs. 4 and 5 show a somewhat modified con- K in 5, and a narrow drip gutter 21 is mounted in any suitable manner directly beneath the lowerrnost corners of said ns.
In Fig. t? a still further modification is shown. This construction comprises a coil section wherein a series of substantially circular fins 28 are secured te a refrigerant conducting tube 29. In this construction the moisture condensing on the cooled fins will run down to a relatively narrow section before dripping therefrom so that a relaf but only by the scope of the claim which follows.
What is claimed is:
In a device of the class described, the combination o! one or more refrigerating sections, each of said sections' comprising one or more refrigerant conducting tubes and a series of fins of polygonal form secured thereto and making intimate thermal contact therewith, means for supporting said sections so that one of thecorners of each of said iins is disposed beneath the others and lies directly beneath said tubes whereby the moisture vadhering to said fins will run toward the lowermost corners thereof before dripping therefrom, and a drip gutter supported longitudinally of each section beneath the said lowermost corners of the ns thereof for receiving the moisture dripping from said tubes and lns, and the transverse dimension of each of said drip gutters being substantially equal to the diameter of said tubes, whereby interference with the natural How of Vair around said sections is reduced to a minimum.
