Critical Solution Temperatures for Ten Different Non-CFC Refrigerants with Fourteen Different Lubricants

S.C. Zoz, M.B. Pate

Abstract

Miscibility data are needed to determine the suitability of refrigerant-lubricant combinations for use in refrigeration systems. A new method for obtaining refrigerant-lubricant miscibility data has been developed, and miscibility data have been obtained for a variety of non-CFC refrigerants and their potential lubricants. The refrigerants include R22, R32, R123, R124, R125, R134, R134a, R142b, R143a and R152a. The lubricants consist of mineral oils, alkylbenzenes, polyglycols and polyolesters with varying viscosities. The miscibility tests were performed in a test facility consisting of a series of miniature test cells submerged in a constant temperature bath. Results are given.
