I have an important NCG question I was hoping one of you engineers could maybe help me with? We all know that the air concentration in the vapor space above a cylinder of R-22 goes up as temperature goes down, due to the condensation of the refrigerant. My question is, what happens to the concentration on the air in the liquid phase in that same tank as the temperature goes down? Does is act like CO2 in water and become more soluble? Or does air act differently in refrigerant and actually decrease in the liquid, with decreased temperature, as it increases in the vapor?

Thanks.
