Lubrifiants : transition et substitution.

Summary

Polyolester oils are the best adapted for all refrigeration applications using HFC. For installation conversion, the miscibility of the new lubricant-refrigerant combination will have to be compatible with the existing circuit and it can be influenced by the percentage of residual oil which must not be arbitrary. The three phases of a conversion are described and the precautions to take are detailed. Miscibility curves are given with an indication of the influence of the percentage of residual oil. The design of the refrigerating circuit and its aptitude to lubricant transfer are useful to find the optimal percentage of residual oil. J.L.
