A comparison of the effects of different lubricants on the in-tube evaporation of an HFC-blend refrigerant.

Author(s) : SUNDARESAN S. G., PATE M. B., DOERR T. M.

Summary

The effects that different lubricants, such as a naphtenic mineral oil, a polyolester, and an alkylbenzene have on the in-tube evaporation of R404A are compared. In-tube evaporation heat transfer coefficient measurements were made in both a smooth tube and a micro-fin tube. The results support the contention that polyolester lubricants exhibit superior heat transfer characterization in relation to other hydrocarbon lubricants.
