D. P. HEATH REFRIGERATING APPARATUS Filed March 6. 1924 Patented Mar. 9,: 1,2926. i j UNITED STATES mitos 1. HEATH, or

' REFRIGERATING APPARATUS.
Application med March 6, 1924. Serial No. 897,182.
To all whom it may concern:
Be it known that I, DnLos' P. HEATH, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new 'and useful Refrigerating Apparatus, of which the following is a specification.
This invention relates to refrigerating apparatus and particularly relates to mechanical refrigerating plants.
It is an object of the invention to provide a mechanical refrigerating plant that may be compactly contained within a chamber and conveniently installed as a unit Within a refrigerator. I
It is a further object to provide for .aircooling of a unit so installed, and to so arrange the motor, compressor and condenser ofthe unit as to be acted upon and effec-v tively cooled in common by the same cooling current of air.
In attaining these objects, the invention contemplates circulating a cooling current of air through a chamber, preferably by means of a suction fan, and locating in said chamber, the motor, compressor and condenser of the apparatus as connected and disposed in unitary relation in the path of said cooling air current, the motor and fan preferably surmounting the compressor adjacent an outlet with the condenser adjacent an inlet to said chamber, the 'expansion coils for the refrigerant being disposed in the cooling chamber of a refrigerator adjacent to but insulated from the rst-mentioned chamber. v
A preferred embodiment of the invention is hereinafter described and is illustrated 'in the accompanying drawing, wherein,
Fig. 1 is a view in elevatlon of the improved apparatus, sectionally showing a re-4 frigerator, wherein said apparatus is installed.
Fig. 2 is a view of the'same in horizontal section, the plane of section being indicated by line 2 2 of Fig. 1.
In these views the reference character 1 designates a refrigerator or thelike, and 2 is a partition wall in said refrigerator, preferab y of a heat-insulating nature, a refrigerating chamber 3 being formed at one side of said partition to receive food or other articles requiring cooling, and a relatively large chamber 4-being formed at the other side of said partition. Within the ch-amber- 4, upon the bottom 5 thereof, there is mounted a unit comprising abase 6, a refrigerant compressor 7 upon said base, a motor 8 surmounting said compressor, and a condenser 9 upon the base at one side 'of the compressor.' The compressor is driven from the motor by a belt 10 engaging pulleys 11 and 12 upon the shafts 13 and 14 of the motor and compressor respectively. A platform 15, -Which carries the motor, is
velevated abovethe outlet head 16 of the comi presser byv standards 17 securedto the compressor by bolts 18, one of said standards being partly broken away in Fig. 1. Upon the motor shaft is mounted fast a suction fan 19 which is disposed within a circular air outlet opening 20 in the upper rear Wall of the chamber 4. The condenser 9 for the refrigerant is formed by a plurality of helical coils, having a common vertical axis, said coils being mounted at one side of the compressor 7 upon a ring 22, which rests upon the base 6 surrounding a circular air inlet opening 23, in said base. Said opening passes also through the door 5 of the chamber 4, communicating with an air duct 24, below said floor, laterally extended and having an inlet portion projecting through a wall of the refrigerator transverse to the wallhaving the outlet opening 20. The' con# denser 9 is adapted to bey supplied at its upper ends with a refrigerant to be condensed through pipes 25 leading from the outlet head 16 of the compressor. The lower ends of the condenser coils are connected in common with a manifold fitting 26 from which the condensed refrigerantis conducted by a pipe 27 to a'boiling or vaporizing coil fo'rmed by a serpentine pipe 28 arranged Within the chamber 3. From said coil 28 the refrigerant is returned to the compressor 7 through a pipe 29. 30 designates the usual expansion Valve controlling the delivery of the refrigerant into the heat-absorbing .coil 28 of the refrigerant circuit.
In the use of the described apparatus,
' the, air current drawn through the chamber 4 by the fan 19, enters 'said chamber through the opening 23, being conductedl to said opening through the refrigerator side wall by the duct 24. Rising through and around the condenser c'oils 9, jthe first effectof the lated heat,is discharged from the chamber 4 (and fromthe refrigeratorlthrough the opening 20. The superposed relation of the motor to the compressor is desirable, in the interest of compactness, and also serves to `arrange the hotter upper portion of the compressor and the motor substantially in the path of the cooling air current.
The unitary grouping and location of all of the. heat inducing `partsv of the lant within a single chamber, through which a cooling current of air is set up to dissipate the heat developed by operation of the plant,
ber havin air outlet 1n its upper portion, a refrigerant condenser arranged within said 'chamber across said inlet, a refrigerant compressor within said chamber adjoining said condenser substantially between said inlet and on'tlet,.a motor -surmounting said compress or. in driving engagement therewith, and
. anexhaust fan driven by said motor in line withsaid outlet for discharging air from said chamber and inducing a flow through said inlet.
2.. In a refrigerating apparatus, a chamber having an air inlet 1n its bottom and having an air outlet, a refrigerant compressor within said chamber substantially between said ,inlet and outlet, drive means for said compressor, means for maintaining a iow of air through said chamber from said inlet to said outlet, and a condenser for the refrigerant having the form of a pipe coiled y adjacent'to and 1n substantial registration saidchamber' from said inlet to said outlet,-
and a refrigerant condenser within .said chamber in close proximity to said inlet having the form of a coiled pipe with substantially coaxial convolutions, and havlng the space within said convolutions substantially registering with `sai-d inlet, whereby the incoming air flows directly axially into and through said convolutions, and is sufiiciently confined thereby to insure its distribution to all of said convolutions.
4. In a refrigerating apparatus, a refri eratorhavinga chamber therein, with an air inlet in its bottom Vand an air outlet in one of its side walls, an air conduit having an` opening in a side wall of the refrigerator and having a delivery connection to said air inlet, means within s aid chamber for inducing a flow of air from said inlet to said outlet, and a refrigerant condensing coil within said chamber havin the space within'its convolutions substantially ,registered with said air inlet.,
