Summary

An effective online mass gain method was designed and constructed to measure the absorption rates and solubility of refrigerants in lubricants. HFC single refrigerants (R32, R125, R134a and R143a), and blended refrigerants (R404A, R407C and R410A) were tested with POE ISO 68 lubricant under various conditions. The experimental results showed that, at room temperature, R134a is the most soluble in POE ISO 68 oil among all the refrigerants tested at pressures of 239 to 446 kilopascals. Among the blended refrigerants tested, R407C was found to be the most soluble at room temperature and pressures of 239 and 446 kilopascals.
