FIELD: chemical engineering. SUBSTANCE: invention is designed to be used in chemical industry, refrigeration technics, and instrumentation engineering, in particular, for preparing cooling agent mixtures for filling refrigeration assemblies and heat-sensitive systems and temperature controlling valves. Aim of invention is to prepare mixtures with specified thermodynamic characteristics with high accuracy. To that end, components are introduced into a vessel at constant temperature and pressure control until their values satisfy predetermined function P = F(T). EFFECT: increased accuracy. |
