My invention relates torefrigeratiiig ma'- chines and more particularly tor such machines of the water cooled'type.
In vmechanical refrigerating machines it is y desirableto keepthe condenser and compressor temperatures as low as possible with- Y in thewOrking range of thepmachine. In household refrigerators it has been found sufficient to provideI an air cooledcondenser over which air circulates by natural draft. However, when the capacity of the machlne 1s increased, it is sometimes desirable to cool` the condenserand the compressor casing by circulating water.
l5 may corrode the'wall of the Compressor casing so that it will not withstand the pressure to which it is subjected. l'
` Accordingly, itis an obj ect of my invention to provide a refrigerating machinehavlng a water coolingsystem arranged about the compressor casing in such manner as to prevent corrosion and deterioration-of the compressor casing. y
Further obJects and advanagesof my 1nvention will become `apparent as the following description proceeds, andthe featuresr of novelty which characterize my invention will be pointed out with articularity in the lclaims annexed to and orming a part 0f this specification. l
For a better understanding of'my invention reference may be had to the accompanying drawing in which Fig. 1 is a `sectional elevation of a refrigerating machine having a cooling device Constructed in accordance with my invention ;-and Fig. 2 is an enlarged side elevation of a lfluid-tight seal having conduitspassingtherethrough.
' Referring to the accompanying drawing, -in Fig. 1- I have showna yrefrigerating ma chinel comprising a motor 'and compressor unit 10 resiliently mounted on helical springs 12 within a Compressor casing 11. vThe base 130i the casingll isrigidly secured to the removal refrigerator top: 14, whichisl supported in an opening inthetop of a cabinet 9, and an'evaporator l5 for cooling the cabinet `is suspended belowf'the top'14 on ,legs 16. A shell 17 forms the upper main portion of the compressor casing 11, and a coning conduit, and the condenser coil'in a jacket This circulating water 'are enclosed by -a jacketV 22, which is secured tact with the condenser coil and is soldered denser -18 i's 'arranged aboutithe casing -in the form of a" helical-fcondi1it connected to the casing 'l1 at 19, the otherend ofthis conduit being connectedto a refrigerant flow control device 2O asshown'at 21. f -In accordancel with my invention I provide water cooling conduit forjicooling theeon- 'fdenser coil, andthe compressor casing, "and `enclose thegcompressor casing,`thewatercoolf containinga suitable liquid or other' substance which efficiently transfers -heat to the water cooling conduit.v Inftheconstruction illustrated the casing A11` andi condenser 18 to the casing bya'ilanged ringf`23 Welded 'to the casing and'tofthe jacket. rA'helical `cooling water conduit 24 isarranged in cony thereto to obtain good heat transfer between them. In order to coolthecompress'orcasing'I ll the jacket 22 with a cooling iluid, which for the sake of clearness, is not shownv on the drawing. The heatofthecompre'ssor casing heats/this fluid and sets up circulating `convection currents therein over the surface of the casingand the cooling water conduit. A fluid-tight seal 25 is provided tov prevent `leakage Awhere the condenseryand 'cooling'.
water conduit pass through the ring 23. The upperiend of the conduit 24 enters a valve chamber 26rat-27 and within thischamber is a thermostatic control device 28 in the 'form of an fexpan'sible bellowswhich regulatesfthe outlet valve 29 for maintaining the desired flow i of the cooling water.V 'The outletilpipe v'30 passes outof the casing -22through afinid- In orderv to prevent deterioration ofthe casing, whichv might 're'snltfvin leakage of refrigerant therefrom, and possiblyl in the bursting of the compressor'jcasing in they type ofinachi'ne illustrated, it is necessary y that thecoolingliquid whichfills the ljacket 22shall not corrodeor rus'tthepshells and 05 the other parts within "the jacket.` I -therefore employ 'a coolingffluidv which issubstantially'chernically `inert with respect to the material ofthe casing and conduits. I
'have found that glycerine, or solutions of 100 potassium carbonate, or sodiumv silicate in water are satisfactory to prevent corrosion of steel parts. -It isapparent that any other suitable liquid may be used to prevent dete- 5 rioration of the parts, and these parts may Vbe made of other materials.
Referring again to Fig. 1, in the operation of the refrigerating machine the refrigerant is compressed in the chamber 11 and passes out through the connection 19 into the condenser c'onduit 18. 'The cooling water flows in through the inlet 32 of the cooling Water conduit 24 and out throu h the outlet 3(.).at a rate controlled by the t ermostatic device 28. As the compressed refrigerant passes downward through the helical coils of the condenser conduit 18, it is cooled and condensed into ali uid b the cooling waterand finally asses t rougil the,connection 21 into vrthe 2, ow controllmgvdevice-20. From the iow controlling device the liquidrefr-igerant Hows, through .the conduit 33 into the evaporator.l5 where it is vaporized upon absorb ing heat from the refrigerator cabinet 9, and u the refrigerant -vaporis then drawn back into the compressor through the conduit 34.. `The cooling water conduit 24 also cools the liquid 7 iny the cooling jacket 22 which in turn VVcools .the compressor casing 17 and themechanism therein suiiiciently to obtain satisfactory op- .v eration,` but not to such an extent asvto cause undue condensation of refrigerant in Y the ,l V"casing, The ltemperature in the condenser 18 n will be-considerably lower than the temperature in the casing 11 because of thedirect cooling ofthe condenser by the cooling water flowing in conduit 24. v s
n Although I have shown a particular emi bodiment of my invention in connection with a compression refrigerating machine, -I do v not desire my invention to Ybe limited thereto,
and intend inthe appended claims toy cover` f allmodiiicatioiis wit in the spirit and scope of my invention.Y v
