DEVELOPMENT OF ENGINEERING DESIGN DATA FOR NEW REFRIGERANTS I: PURE FLUIDS AND AZEOTROPIC MIXTURES

摘要

It is important to correlate thermodynamic data for replacements for CFCs and HCFCs and present it in a form that will allow industry to design equipment from charts rather than complicated thermodynamic equations. This paper outlines the development of such equations for the more popular of these fluids. Sample pressure-enthalpy diagrams are then given for the pure fluids. In addition, since replacements for CFCs and HCFCs can be formed from both zeotropic and azeotropic mixtures of these fluids, the use of a typical mixing rule is discussed and initial results presented.
