CASSIUS cLaY PALMER, or nnwyonaiiu. .ar.
n nrnrennarine Enema,
1 Application filed September 27, 1919, Serial No. 326,882. Renewed mat 25.1924.
To all whom it may concern: Be it known that I, CAssIUs CLAY a citizen of the United States, residing at v New York city, borough of Manhattan, in
,fithe-county and State of New York, have invented certain new and useful Improve ments in RefrigeratingMachines, of which the following is a specification. 1 My present invention relates to refrigerating machines in which the refrigeration is brought about by the compression and expansion of gases, and particularly such a machine which shall be small, compact and self-contained, so that it may be used in small units such as for domestic purposes, with a minimum cost for installation and upkeep.
With these and other objects in view my invention consists of the construction and arrangement hereinafter described, and more s cifically pointed out in the claim.
In t e drawings, Figure 1. is a side elevation partly in section, of an illustrative form of my invention, and Fig.2 is an end elevation also partly in section, of the construction shown in Figure 1.
The corresponding parts are referred to both in the specification and in the draw- I in s b similar reference characters.
30 n the illustrative form of machine shown in the drawings an ice box or space to be refrigerated is-shown, having a chamber 11, in which is supported an expansion grid 12 which may be of any type suited for the particular purpose for w ich the refrigerator is to be used, the form illustrated comprising a series of headers 13, 13 connected by pipes 14 and provided with an outlet valve 15.
Mounted on the casing 10 is a tank 16, and also supported by the casing 10 and within the tank 16, are the various parts which constitute the mechanism for the compression of the gases. A pump 17 of any preferred type, but as shown herein of the rotary type, has its inlet side connected by the pipe 18 to the expansion grid 12, and its outlet side connected by pipes 19' and 27 with a header 20 which constitutes the upper part of a condenser, which is made up of a lower header 21 and a series of vertical pipes 22, 22. Between the pump 17 and the pipe 19 I preferably insert a separator 23 provided with baflies, in a well-known way, to remove the lubricant which may be ALMER,
carried over gases. I a
The lower header 21 ofthe condenser is from the compressor by the *connected by the pi e 24 with the expansion grid'l2, this pipe expansion valve 25 the usual forms. V v
Above the header 20 of the condenser is sing-provided with an which may be ofany of mounted a spray pipe 26 connected by a pipe 271 to a pump 28 which may be of anysuitable type and "which, as herein shown, is driven by the eccentric 29 on the end of the pump shaft. The inlet 30 of the pump 28 is located in the tank 16.
In my preferred form the pipes 22 of the condenser are covered with a fabric material which is adapted to hold water, such material being of any of the well-known forms, such as cheese cloth or the like.
Preferably, I surround three sides of the 7 condenser with a flue-like arrangement 31 having an opening 32 at the top, the flue 31 being cut away so that a fan 33 may direct a blast of air against, the pipes 22. This fan is driven by suitable gearing from a source of power such as the motor 34, this motor also being connected by suitable gearing with the shaft of the compressor 17.
In the operation of the device just described, the tank 16 is filled with water so that the level thereof is preferably above the shaft of the pump, and sufficient quantity of the material to be com essed and expanded, which. preferably is et yl chloride, is introduced lnto the condenser through valve 35, and the latter is then closed. On starting the motor the refrigerant is expanded in the grid 12, compressed in the pump 17 and cooled in the vertical condenser ready for expansion again through the valve 25 into the grid 12, all inlthe well-known cycle of such refrigerants. The compressed gas isv cooled in the condenser by the spray of water delivered through the pipe 26, which passes down the pipes 22 and is held thereagainst ready for evaporation by the fabric surroundin these pipes when such fabric is used. 'fiie water from the spray pipe 26 is caught in the tank 16 from which it is pumped up again by the pump 28. There is therefore a self-contained, circulatory, waterspraying system, to which new water need be added only as the evaporation thereof decreases thequantity in the tank 16. Such addition may be made, if desired, by a pipe controlled by a float or in any other wellknown manner. The fan-33 directs a current of air against the pipes 22, which causes the water thereon to be evaporated to absorb the heat, and this water-charged air is carried off through the opening 32.
By submerg'ing a large part of the and particularly the shaft thereof, an by submerging the water pump 28, ,I have provided a means by which a considerable quantity of the'heat developed in the mechanical operation of the machine, will be absorbed directlyeby the water in the tank 16, which heat will be, of course, dissipated by the evaporation of this water when exposedon the pipes 22. a V
B arranging the tank 16 so that the water use in the spray 26 will be caught therein and recirculated, I have provided an efiicient means by which the quantity of water used will be reduced to the quantity the evaporation on the pipes 22.
lost through mum amount of mec anical skill or care is available, and yet will operate with great efiiciency.
In a refrigerating apparatus, an expansion, grid, a condenser, a compressor, pipe connections between said grid and said compressor and between said condenser and said grid, a water tank located beneath said condenser and adapted to hold water in contact with a large part of the walls of said compressor, a spraying apparatus, including a pump, to spray the water from said tank over said condenser, and a fan to force a current of air against said condenser, said compressor, pump and fan being operated from a single source of power. a
