Performance 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...

Rheology of Disperse Systems

The rheology of disperse systems is an important processing parameter. Being able to characterize and manipulate the flow behavior of dispersions one can ensure their optimal performance. Waterborne automotive coatings, for example, should exhibit a distinct low-shear viscosity necessary to provide good leveling but to avoid sagging at the same time. Then, a strong degree of shear thinning is n...

Optimal Synthesis of a Cascade Refrigeration System of LNG Through MINLP Model for Pure Refrigerant Cycles

 liquefied natural gas (LNG) is the most economical way of transporting natural gas (NG) over long distances. Liquefaction of NG by using vapor compression refrigeration system requires high operating and capital cost. Due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...
