| 简介 |
A method of improving performance of refrigerant systems such as refrigerators and air conditioners that utilize a re-frigerant working fluid. The working fluid consists essentially of a heat transfer fluid and a lubricant that is miscible and is otherwise compatible with the heat transfer fluid at all operating temperatures of the refrigerant system. The method is directed particularly to chlorine-free fluoro-group organic fluids and more particularly to hydrofluorocarbon heat transfer fluids. The preferred lubricants comprise polyol ester basestocks and compounded polyol esters that are highly miscible with such hydrofluorocarbon heat transfer fluids. |
