Summary

ASHRAE 41.4 standard [1] proposes a methodology to estimate the oil mass flow in a refrigeration cycle. However, the procedure itself is tedious and invasive. In this study, another method is analysed which offers an online, non-invasive and qualitative estimation of the oil mass flow.
The performance of this method has been tested in the characterization of the oil circulation rate (OCR) of a refrigeration system driven by a variable speed compressor in which the effect of the speed of the compressor and the evaporating temperature (suction specific volume) on the OCR is analysed over a set of 36 tests.
