摘 要
幾乎所有的蒸汽式壓縮制冷系統(tǒng)都需要潤滑油，尤其是對于壓縮機(jī)的正常運(yùn)作來講，然而有一部分潤滑油總是和制冷劑一起通過整個(gè)循環(huán)。這個(gè)循環(huán)的起源卻偏離了理論循環(huán)（即基于純制冷劑）的組成部分，本文的目的是討論與潤滑油有關(guān)的研究領(lǐng)域中的制冷。以前的評論中的文獻(xiàn)側(cè)重于熱工水力后果的存在潤滑油的重要性；在這里，我們將分析其熱力學(xué)后果。在第一部分，簡要的文獻(xiàn)將概述潤滑油的作為一部分或?qū)φ麄€(gè)制冷系統(tǒng)當(dāng)前的科學(xué)和技術(shù)問題的影響。對這個(gè)采用的方法或技術(shù)將加以描述。這些研究需要健全的工具評價(jià)熱力學(xué)性質(zhì)的制冷劑，油性混合物。 第二部分，本文是一次嚴(yán)格的述評，因此這些工具，并特別側(cè)重液體蒸汽平衡，吸收擴(kuò)散，以及混合焓計(jì)算。

Abstract

A lubrication agent is necessary in almost all the refrigeration vapor compression systems, particularly for the correct operation of the compressor. However, a certain portion of the oil always circulates with the refrigerant through the cycle. This circulation is at the origin oaf deviation from the theoretical behavior (i.e. based on pure refrigerant) of the components. This article aims at reviewing the oil-related researches in the field of refrigeration. Previous reviews in the literature focused on the thermo-hydraulic consequences of the presence of oil; we will analyses here its thermo dynamical consequences. In a first part, a brief literature review will give an overview of current scientific and technological issues concerning the impact of oil on components or on whole refrigeration systems. The typical approaches and methods employed to address this problem will be described. These researches require sound tools for the eva luation of thermodynamic properties of refrigerant–oil mixtures. The second part of this article is hence a critical review of these tools, and focuses particularly on liquid–vapour equilibrium, absorption–diffusion, and mixture enthalpy calculation.
