Comparative Analysis of Equations of State for Calculating the Thermodynamic Properties of a Vapor-Liquid Multicomponent Refrigerant Blend Comprising the Working Fluid of a Low-Temperature Throttling Refrigeration Unit

  • Published:
Chemical and Petroleum Engineering Aims and scope

The computation methods of the thermodynamic properties are used for theoretical studies of multicomponent refrigerant blends (MRBs) for low-temperature throttling refrigeration units, providing cryostatting modes for cooled objects in the temperature range of –90 – –160 °С. The article presents the comparative analysis of the state equations for calculating thermodynamic properties of multicomponent refrigerant mixtures. Quantitative and qualitative differences in the results of calculations in the lowtemperature region are determined.
