Method and system for the determination of a ternary refrigerant mixture composition

摘要

A method for determining the composition of a ternary refrigerant in a refrigeration system. The method calculates the composition of the ternary refrigerant under the assumption that the expansion cycle is isenthalpic and that the ratio of two components in the ternary mixture remain fixed in relation to one another before and after the expansion. These assumptions permit the calculation of composition of a ternary mixture with relatively few inputs.
