Abstract

A pressure-enthalpy diagram for the real refrigerant R134a / Castrol Icematic SW22 has been developed.

The influence of the oil impuriries on configuration of main isolines in the diagram was considered. The role of use of the offered diagram in theoretical evaluation of the efficiency of refrigerating equipment is highlighted.
