| Abstract | The report gives results of miscibility, solubility, and viscosity measurements of refrigerant R-236ea with three potential lubricants. The lubricants were a mineral oil, alkylbenzene, and polyol ester, each with a nominal viscosity of 68 cSt. The miscibility tests were performed in a test facility consisting of a series of miniature test cells in a constant-temperature bath. Critical solution temperatures obtained from the miscibility data are presented for each refrigerant/lubricant combination. In addition to miscibility data, both solubility and viscosity data were obtained for R-236ea and the most promising lubricant. For comparison purposes, data were also taken for the existing U.S. Navy shipboard chiller refrigerant and lubricant concentration, namely 4-114 and a naphthenic oil. |
