Abstract

Herein disclosed is a lubricant oil or lubricant for the compressor of a refrigeration system which operates with a refrigerant comprising at least one component of the hydrocarbon (HC) group of refrigerants, (a) whereby the lubricant consists of at least 85 weight% of alkylbenzene having an average molecular weight of >= 160 g / mol and exhibiting a viscosity of 2.2 - 3.0 centistokes (cSt) at 40degC; optionally wherein the alkylbenzene consists of at least 85wt% of linear (straight chain) alkylbenzene, having an average molecular weight of >= 160 g / mol and exhibiting a viscosity of 2.2 - 3.0 centistokes (cSt) at 40 degC; (b) or alternatively whereby the lubricant consists of at least 85 weight% of alkylbenzene having an average molecular weight of >= 190 g / mol and having a viscosity of 2.5 - 3.5 cSt at 40 degC; optionally wherein the alkylbenzene consists of at least 85wt% of linear (straight chain) alkylbenzene, having an average molecular weight of >= 190 g / mol and exhibiting a viscosity of 2.5 - 3.5 centistokes (cSt) at 40 degC.

Description

[0001] Statement on government funding for research and development [0002] Not applicable. Technical field [0003] In general, the present invention relates to lubricating oil compositions and uses thereof. In particular, the present invention discusses low-viscosity lubricating oils suitable for applications such as refrigerators using hydrocarbon refrigerants. Background technique [0004] Use hydrocarbon refrigerant R600a (isobutane, CH (CH 3 ) 2 CH 3 ) And R290 (propane, CH 3 CH 2 CH 3 ) To replace HCFC (hydrochlorofluorocarbon) and HFC (hydrofluorocarbon) compounds are becoming more and more widely, this is because these two hydrocarbon refrigerants have negligible global warming potential and 0.0 ozone depletion potential ( ODP). [0005] Recently, HCFC and HFC gas (such as HCFCR22 (chlorodifluoromethane, CHClF 2 ), HFCR134a (1,1,1,2-tetrafluoroethane, CH 2 FCF 3 The impact of global warming caused by )) has been concerned, which has increased the use of hydrocarbons as ref...
