' Specification of Letters Patent.

To allwhom it may concern: I

:Be it known that I, PETER J. LEYEN1 DECKER, a citizen of the United States, residing in Haddonfield, Camden county,

in Condensers, (being a division of my'application for patent for improvements in condensers filed January 28, 1913, Serial No. 744,775,) of which the following. is a speci 1O fication.

My invention consists of improvements in condensers of the type for example as-those used for refrigerating purposes where am-. monia gas is liquefied and used as a cooling.

15 agent.

The chief object of my invention is to affect a quicker condensation of ammonia and other gases than has been accomplished heretofore, and to do the same with a less num- 2 ber of pipes.

Another object is to produce than has heretofore been produced by condensers of the same size.

These and other objects which will be de- 25 scribed hereinafter I attain in the following manner reference being had to the accompanying drawing in which, I

Figure 1, is a side elevation of a condenser constructed in accordance with my invention; Fi 2, is an end elevation of Fig. 1 looking rom the left; and Fig. 3, is an enlarged section of a detail of my invention showing a liquid-ejecting nozzle which I employ.

Referring to the drawings, Fig. 2 shows a series of three stacks of condensing coils 1, 2 and 3 and as all of the said stacks are of similar construction I will describe only one in detail. Each stack comprises a plurality of tubes 4, 5, 6,7, 8, 9, 10, 11, 12,13, 14., 15 and 16, which are connected at their rear ends by bends 17 of any well known construction. The tubes 11 and 12, and 13 and 14 are respectively connected together at 45 their forward ends by bends 18 which may be similar in construction to bends 17. Bends 19 connect the forward ends of the tubes and 6, 7 and 8, and 9 and respectively; the bend 20 which connects the tube 50 15 with the tube 16 being of such construction as to allow a pipe 21 connected thereto to lead to a header or liquid ammonia takeoif pipe 22 which extends transversely to the stacks 1, 2 and 3, or any number of stacks 55 which may be employed in the condenser.

New- 5 Jersey, have invented certain Improvements a cooler liquid The pipe 16 extending upwardly from the. rear end of the tube 16 and which is shown lorokelbofi' in Fig. 1, may-be led to an equalzing chamber in a manner which is in com- ;mon practice in the art and may also be connected to a foul gas reservoir in "any well .known manner. A pipe 23 connects, the header 22 with .a liquid supply pipe or header 24 which extends transversely to and at the base of the said stacks. The main sup ply inlet for the ammonia gas consists of the large header 25 which extends transversely to the stacks '(Fig. 2) and has a series of take- off pipes 26, 27 and 28 prefer- ;ably one for each stack of tubes. These take-0E. pipes connect respectively with the forward ends 29 of the bottom tubes 4 and.

supply the ammonia gas, which is under pressure, to the coils so that it can pass or circulate through the several tubes comprising each coil or stack. Each of the pipes 26, 27 and 28 is provided with a T-joint 30 which'is bored at 31 (Fig. 3) for the recep tion of a nozzle 32 having an ejecting opening 33 of small diameter. These nozzles 32 are each connected by piping 34 to the liquidfsupply pipe or header 24. The nozzles 32 are so arranged that their upper ends 35 extend and open into the interior of the pipes 26, 27, and 28 respectively and are in free communication therewith. pipes 26, 27 and 28- is connected to certain Each of the v Patented Sept. 1, 1914.- 1913, Serial No. 744,775. Divided and this. application filed August 18, 1918. Serial No. 785,358.

pipes of the stacks by relay pipes 36, 37 and 38 which respectively pass through the bends 19 and are provided with nozzles 39, 40 and 41; each having an ejection bore 42 of small diameter. The nozzle 39 is so arranged as to project into the interior of the pipe 10 and is surrounded by a sleeve 43 having an inner diameter greater than the outer diameter of the end of the nozzle. This sleeve is provided with ports 44 which are adjacent the end of the nozzle. In like ,manner the nozzles 40 and 41 respectively are connected to deliver to the tubes 8 and 6, and are each surrounded by a sleeve 43 similar to that just described. Regulating valves may be placed in all or any of the several pipes if desired. ,1

The nozzles 39, 40 and 41 and their co operating sleeves 43 as well as the function of the tube 16 are described in detail in my application for patent, Serial No. 744,775, filed January 28, 1913, of which this application is a division, therefore said parts are not claimed herein as they are claimed in my said parent application.

The following is a description of the operation of such parts of my invention as rev late'to the feature of injecting liquid ammonia into the condenser coil through the nozzles 32. Water is allowed to trickle or run over the tubes of the condenser-from the top to the bottom from a suitable source such shown by the arrows in Figs. 1 and 2. At

the same time a certain amount" of the. previously condensed or liquid ammonia, which passes from the pipe 21 of each coil into the eader 22 and down through the pipe 23 to the header 24, passes through the nozzles 32 and is injected in spray form into the interior-of the respective pipes 26, 27 and 28,

containing the ammonia gas. The movement of the gas passing through the said latter pipes carries the said liquid ammonia through the tubes of the coil in a precipitated form and forms a mixture of ammonia gas and liquid ammonia. Thus, the ammonia gas from the time it first enters the condenser coils has liquid ammonia mixed therewith in a precipitated formal. e.,s'mal1globules or particles of liquid ammonia are suspended within the ammonia gas. This mix ture of ammonia as and liquid passes through the coils and as the liquid ammonia is a better conductor of'heat than the am monia gas it will tend to quickly relieve the gas of its heat and convey it to the pipes where it will be taken up by the cold water flowing thereover. Therefore since ammonia gas under pressure liquefies when cooled it is obvious that by forcing a spray of .liquid ammonia into contact with the gas as the latter enters the tubes of thecondenser densation t ereof is ex edited.

WVhile I have descri (1 my invent-ion as being employed in thetreatment of ammonia; gas the same may be advantageously used to condense other ases such, for exam- 5 0.-,ple, as carbon dioxid CO in each case a portion ofthe condensed liquid being passed .portion of the coil. g
