Abstract
A performance enhancing additive is introduced into a vapor compression system used in cooling and the like. The additive is selected from a class of compounds, e.g. tetraglyme, and added in a predetermined concentration measured relative to the mass of the system's lubricant. The additive can be soluble or non-soluble in the lubricant used in the system's single-phase compressor. It can be added anywhere in the system to provide lower thermodynamic load on the system compressor.
