Investigation on the miscibility of lubricating oils with refrigerants by means of neutron radiography. Application to the formulation of oils compatible with HFC refrigerants.

Author(s) : PARQUET J. du, PIRAS A., BAYON G.

Summary

Neutron radiography is known as a useful technique for visualizing the flows of hydrogen containing fluids such as water or lubricating oils in metallic circuits. It makes it possible to visualize the phase separation at low temperature of non-miscible refrigerants and oils in real operating conditions. In the case of miscible fluids, it is possible to follow the gradual mixing. The method has been applied to the development of R134a compatible oils and can be applied to evaluate the miscibility of these oils with R404A for example.
