Low loss measurement of oil concentration in a refrigerant-oil mixture in a liquid line.

Author(s) : MCGOVERN J. A.

Type of article: Article, IJR article

Summary

A method of measuring the mass concentration of lubricating oil in a refrigerant-oil mixture in a liquid line within a refrigeration system is described. It is suitable for use where the oil and refrigerant are fully miscible in the liquid phase, e.g. for mineral oil and R12. The technique involves taking a small liquid sample, measuring its volume, venting the refrigerant back into the system and weighing the residual oil. Many measurements can be made, with negligible loss of refrigerant from the system. An application of the method to a split circuit bypass type compressor load stand is also described.
