Composition shift of the mixtures R125-R236fa (49.4-50.6) and R509A.

Author(s) : BOBBO S., ZILIO C., CORTELLA G., CAMPORESE R.

Summary

A shift in the composition of a refrigerant mixture in a refrigerating circuit is a phenomenon related to the thermophysical properties of the mixture and lubricating oil, the refrigerant-lubricant mass ratio in the circuit, and the features of the plant concerned. This phenomenon may also be accentuated by any leakage or by unsuitable charging procedures. The paper gives a detailed description of a method for measuring the circulating composition of a mixture. The method calls for the use of a gas chromatograph connected directly to the circuit so as to enable in-line analyses.
