REFRIGERANT LUBRICANT AND METHOD OF LUBRICATING 'REFRIGERATING MACHINERY.
No Drawing.
{This invention relates to the lubrication of refrigerating machinery and more partic-ularly of that type of refrigerating machinery wherein methyl'or ethyl chloride is 5 employed as the refrigerant medium.
The usual lubricant which has been used inthis art in conjunction with refrigerants such as ethyl or-methyl chloride has been glycerine for which, prior to my discovery,
no satisfactory substitute has been known. While in many respects glycerine is quite satisfactory, it possesses certain properties which render it far from being an ideal lu bricant in refrigeration systems. 'For example,
it is highly viscous and yet there has heretofore been no diflicultly freezing diluent which could be used to reduce its viscosity and that would at thesame time not mix with the refrigerant. Moreover, if a refrigerating machine employing glycerine as the lubricant is allowed to run at a relatively high:
temperature, so as to render the glycerine less viscous, there is a serious increase of the existing tendency to decomposition of the glycerine, by overheating, into compounds such as fatty acids, carbonic acid, carbon and water which act on the materials used in the construction of the refrigerating machinery and especially on the copper and the high carbon steel surfaces thereof.
Furthermore, the water liberated by such decomposition tends to break down refrigerant liquids such as ethyl chloride to form alcohol and hydrochloric acid. My investigations have led to the discovery that by the employment of a'glycol, such as the propylene glycol 'commonly' known as 'tri-methylene glycol, as such lubricant, many of the objectionable features accompanying 40 the use of glycerine can be largely eliminated. Trimethylen-e glycol is inert toward metals and not miscible withrefrigerantssuch as ethyl or methyl chloride in liquid form,.and
. because of its low viscosity it reduces the power consumption of the machine and the heating of the A glycol can as the refrigerant without interferin the operation of the machine. Trimet iylene glycol can be used at temperatures as low as s r. to 10 earings.

consumption. This is in marked contrast to glycerine which, at about 20 F., becomes too viscous to flow properly to thebearings.
\Vhile I prefer to use trimethylene glycol,
HOCH CH CH OH, other propyleneglycols such as that represented by the structural formula CH CHOHCH OH, the hydroxyl groups being. attached to adjacent carbon atoms, may also be .used, as may ethylene and butylene glycols and polymers of the glycols, without departing from the spirit of the invention.
It is important that the glycol employed, as well as the refrigerant employed, especially when the; refrigerant is ethylene chloride should be approximately anhydrous, i. e. should not contain more than about 2% of water and preferably should contain as low as of water, as otherwise the ethylene chloride will be decomposed or hydrolyzed by the water into hydrochloric acid and ethyl alcohol, the former being obviously extremely corrosive to metals and the latter not possessing the properties desired in refrigerant for the purposes herein described.
While I preferably employ ethylene or methylene chloride or a mixture thereof as refrigerating media, chlor-hydrocarbons of! I the fatty series capable of substitution there for are equally within the scope of the appended claims.
Having thusdescribed my invention,-what I claim and desire to obtain by Letters Patent is:
1. "A lubricant for refrigerating machines containing a glycol.
2. An approximately anhydrouslubricant 1 i for refrigerating machines containing a propylene glycol. I
3. A lubricant for refrigerating-machines containing a glycol having less than 2% of water.
4. A lubricant for refrigerating machines containing trimethylene glycol.
5. A lubricant for refrigeratingniachines containing trimethylene glycol having less than 2% of water. 7
