With the increasing trend towards environmental friendly refrigerants, studies on natural refrigerants such as CO_2 have been conducted. This paper describes an analytical approach to explain a certain phenomenon inside a lubrication film, where the concentration of refrigerant changes inaccordingly to Henry's law, observed in previous experiments done with FT-IR. A theoretical model using Reynold's equation and diffusion equation was presented and numerical calculations are carried out for several sliding conditions. The calculation results were compared with measured results using FT-IR. It was also found that an increase in load results in a reduction in refrigerant concentration, and a decrease in sliding velocity results in a reduction in concentration at the entrainment area.
