The new refrigerant fluids are generally not compatible with traditional mineral oils used for the lubrification of
compressors. Different typologies of oils have been proposed, such as polyalkylene glycol (PAG), alkylbenzene
(AB), and polyol ester (POE) oils. New thermodynamic models are necessary to describe well the behavior of
these fluids, but at the moment only few experimental data are available in the literature. The work presented in
this paper is part of our research program aimed to evaluate the solubility of refrigerants in commercial oils. The
density of five different pentaerythritol esters is presented, which are used as components of the commercial POE
oils (i.e., pentaerythritol ester of butyric acid (PEC4), pentaerythritol ester of valeric acid (PEC5), pentaerythritol
ester of hexanoic acid (PEC6), pentaerythritol ester of heptanoic acid (PEC7), and pentaerythritol ester of octanoic
acid (PEC8)). The experimental compressed liquid density data were correlated by means of a particular equation
that is also presented in this paper.
