In the previous publication it was shown, that binary mixes with three-phase equilibrium (liquid-liquid-vapor) as working bodies of Linde refrigerators on levels temperatures of cooling 120, 150 and 200 К enable essentially to improve power characteristics of a regenerative cycle with unitary throttle control. In the given publication continuing cycle articles on the theory of Linde refrigerators, questions of the proved choice of components for formation of effective three-componential mixtures are considered, problems definition optimum structures such mixtures and pressure in the valid cycles of Linde refrigerators appropriate extremums of refrigerating capacity or exergtic efficiency are solved. Optimization calculations confirm increase refrigerating capacity and exergtic efficiency of Linde refrigerators at transition with binary on three-componential mixtures of optimum structures.
