Lubricants for refrigerant systems with low global warming potential

摘要

The disclosed technology relates to a working fluid for a refrigeration system of a low global warming potential (GWP) comprising a compressor, wherein the working fluid comprises a polyol ester oil, an alkylbenzene oil, and a low GWP refrigerant, Wherein the mixture of carboxylic acids comprises at least one linear carboxylic acid having 8 to 10 carbon atoms. The disclosed technique is based on the use of commercially available low GWP working fluids (such as commercially available working fluids based on low GWP refrigerants) that do not have the solubility and / or miscibility problems typically observed in low GWP fluids, including high viscosity fluids and applications. ).
