THE IMPORTANCE OF INCLUDING THE LIQUID PHASE IN EQUATIONS OF STATE FOR NON-AZEOTROPIC REFRIGERANT MIXTURES.

Summary

THE IDEAL MIXTURE ASSUMPTION CAN BE USEFUL BUT CAN ALSO BE SERIOUSLY IN ERROR WHEN ONE OF THE COMPONENTS IS NEAR ITS CRITICAL POINT, EVEN WHEN THE MIXTURE IS NOT NEAR ITS OWN CRITICAL POINT. A PHYSICAL MODEL IS SUGGESTED FOR A MIXTURE WHOSE EQUATION OF STATE INCORPORATES ALL THE DEPARTURES OF THE MIXTURE FROM IDEALITY, WHICH ALLOWS SMALL, ISOLATED SETS OF DATA TO BE USED IN PREDICTING OTHER PHYSICAL PROPERTIES OF BOTH THE PURE FLUIDS AND THEIR MIXTURES.
