摘 要
几乎所有的蒸汽式压缩制冷系统都需要润滑油，尤其是对于压缩机的正常运作来讲，然而有一部分润滑油总是和制冷剂一起通过整个循环。这个循环的起源却偏离了理论循环（即基于纯制冷剂）的组成部分，本文的目的是讨论与润滑油有关的研究领域中的制冷。以前的评论中的文献侧重于热工水力后果的存在润滑油的重要性；在这里，我们将分析其热力学后果。在第一部分，简要的文献将概述润滑油的作为一部分或对整个制冷系统当前的科学和技术问题的影响。对这个采用的方法或技术将加以描述。这些研究需要健全的工具评价热力学性质的制冷剂，油性混合物。 第二部分，本文是一次严格的述评，因此这些工具，并特别侧重液体蒸汽平衡，吸收扩散，以及混合焓计算。

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.
Key words: refrigeration system; compression system; eva luationforlubricating oil; procedure; measurement method; solubility modeling
