IMPROVEMENT IN REFRIGERATING APPARATUS.
Specification forming part of Letters Patent No. 202,509, dated April 16, 1878; application filed October 1, 1877.
"object is to obtain an improved application of this process for the important purpose of preserving meat or other food or beverages. In attempts hitherto made to practically apply the process referred to difficulties have been met with through the freezing of moisture contained in the air during its expansion, and our improved apparatus is especially designed to avoid-such difficulties by means which insure that the proportion of moisture in the air at the time when it expands shall not be sufficient for the formation of ice or frozen particles.
The accompanying drawing is a vertical section of our improved apparatus.
The apparatus is designed for the air to be passed through on its way from the cylinder or cylinders in which it is compressed to the cylinder or cylinders in which it is expanded. The well-known process of cooling the air, while being compressed, by injecting water into the cylinder in which the compression is effected, or by incasing tho compressing-cylinder in a water-jacket, or in both ways, is intendedto be used in carrying out our invention, and the use of our apparatus, hereinafter described, is to be additional to, and not instead of, such lenown process. v
The apparatus we employ comprises two vertical cylinders, A B, or vessels of any convenient and suitable form, and a set of pipes, G. The first vessel A is formed with an inlet, D, at its lower part for the admission of the compressed airfrom the compressing-cylinders, the air passing upward through this first vessel A, then across, by a connecting-passage, E, to the top of the second vessel B, in which vessel it descends, and from the lower part of whichit passes into the set of pipes (J. At
the top of the first vessel A there is fitted a pipe, F, for the introduction of water of Ordinary temperature, (or colder, when conveniently obtainable,) such water being forced by V it being important that the air and water should intermingle intimately while the air passes upward and the water downward.
To insure complete contact and action between the water and air, so that the water may abstract as much as possible of the heat rendered sensible by the compression of the air, the vessel A is provided with suitable materials, down through which the water may drip while the air passes upward through the interstices. For this purpose we employ a number of perforated metal diaphragms, H, which are fixed across the lower part of the vessel A, but above the air-inlet D, and it is best to arrange these diaphragms with the holes in each opposite the solid metal of the next above and below, in order that the subdivided currents may hat e their directions continually changed, and be thereby made to impinge upon the wetted surfaces of the diaphragms. Similar diaphragms I are fitted in the second vessel B; or any equivalent arrangement of materials may be substituted for the diaphragms I. The purpose of this second series of diaphragms I in the Second vessel B is in a sense the reverse of that of the first series H in the first vessel A. The first series- H are for bringing the air and water closely together; the second series I are for separating as completely as possible from the air any moisture it carries over from the vesselAinto the vessel 13. The jets of air, passing through the perforations in each plate I in succession, impinge on the next plate, and deposit the suspended moisture on the plates. At the bottom of each vessel A B there is a casing,.J K, to receive the water, which may be withdrawn therefrom periodically or continuously through any suitable water-trap valves.
Assuming that the water employed and introduced by the pipe F is of the ordinary temperature, it cannot, of course, reduce the heat of the air below that temperature, and at this temperature the air will still retain some moisture, which will be precipitated and possibly congealed on the air being subsequently expanded and becoming of considerably lower temperature. It is the purpose of the set of pipes O to cause the separation and deposition from the air before it reaches the expansion-cylinder of any moisture which would thus tend to congeal, and thereby interfere with the proper Working of the apparatus. These pipes G are placed in an atmosphere of a lower than the ordinary temperature, and, being inclined upward from the vessel B, the moisture deposited in them in consequence of the additional cooling of the air in passing through them drains back from them into the vessel B. We place the pipes O in the chamber M, in which the meat or other substances to be preserved by maintaining a low temperature are placed, and thereby obtain the required cooler atmosphere in the most convenient and economical manner. The object of passing this compressed air through pipes in the provisionchamber M is not for the purpose of cooling the air in this chamber; but, on the contrary, the object is to complete the cooling of the air in its compressed state in these pipes by the cold air of the provisionchamber, and this before this compressed air passes into the expansion-cylinder, where its ra{efaction produces the required degree of co d.
The pipes '0 should be of considerablelength, the precise length in each case depending on the temperature intended to be maintained in f the chamber M and other circumstances.
Where several chambers M are to be kept cool by the same refrigerating apparatus-for example, a number of vans composing av rail way-train, or several separate compartments ir Q a ship-the pipes C may be arranged in only one compartment of the series. I We clalm as our mvention- 1. Inarefrigerating structure, cooled by the 1 expansion of compressed air, a series of pipes conveying the compressed air and passingf through the refrigerating-chamber, substantially as and for the purpose set forth.
refrigerating-chamloer all substantially as d. scribed.
In testimony whereof we have signedoui names to this specification in the presence of two subscribing witnesses.
