An Analytical Equation of State for Saturated Liquid Refrigerant Ternary Mixtures
In this work an analytical equation of state has been employed to calculate the PVT properties ofternary refrigerant mixtures. The theoretical EoS is that of Ihm, Song and Mason, which is based onstatistical-mechanical perturbation theory, and the two constants are enthalpy of vaporization ΔHvapand molar density ρnb, both at the normal boiling temperature. The following three temperaturedepende...
متن کاملTechnical Effects of Air Cooled Blast Furnace Slag on Asphalt Mixtures
Air cooled blast furnace slag is a by product made of gradually air cooled molten blast furnace slag and is often stored in stockpiles near the iron mills and usually occupy a wide area around the iron mills. From this perspective the further use of these materials can have its own merits. Air cooled blast furnace slag can be used in asphalt mixtures because of their proper frictional propertie...
متن کاملMixture Boiling
This chapter provides the engineer and the researcher with correlations and models for the prediction of the critical aspects of the boiling heat transfer of mixtures. This chapter offers a reliable, hands-on resource for solving common problems across pool boiling and flow boiling applications such as miscible mixtures, refrigerant/lubricant mixtures, additives, and refrigerant/nanolubricants....
متن کاملPerformance and Leakage Investigations of Refrigeration and Airconditioning Systems Using Refrigerant Mixtures as Working Fluids
In spite of the advantages of zeotropic refrigerant mixtur~" [1], the industrial >tpplications of mixtures have been very limited up to now. The major problem is seen iu the leakages occuring in refrigeration plants and so a possible change in composition. Another disadvantage is that no simple methods for determination of the concentratiou insick the t:ydc i\rc available. This paper pre$ents t...
متن کاملDevelopment of High-Temperature Heat Pump Using
four kinds of refrigerant mixtures R22/Rl34a, R22/Rl52a, R22/Rl42b and R22/Rl23, which contain some new halocarbons which are considered to be the alternatives for CFCs, were evaluated in order to realize higher condensing temperature than that using R22 at high temperature operation, and larger heating capacity than that using R22/Rll4 at normal temperature operation. These mixtures were appli...
