Abstract

Thermodynamic properties of R134a (1,1,1,2-Tetrafluoroethane) and R718 (water) have been developed as a Microsoft Excel add-in called ThermoAnalysis. The mathematical correlations for the thermodynamic properties of R134a and R718 were formulated from well-known equations of state and used to develop ThermoAnalysis based on a computer program in Microsoft Excel Visual Basic for Application language. ThermoAnalysis provides thermodynamic properties for the saturated regions for R134a and R718 refrigerants, and the subcooled and superheated regions of R718 refrigerant. The calculated values are accurate compared to the standard properties tables for refrigerants. A typical thermo-fluid problem was discussed to illustrate how ThermoAnalysis can be used for practical problem solving. Generated properties’ data can be easily used in the Excel spreadsheet for process analysis, simulation and design of systems that use R134a and R718. ThermoAnalysis is handy for both students and practicing thermo-fluid engineers.
