thermodynamic analysis of refrigerators using different refrigerants

چکیده
refrigerants that are used in refrigeration systems, cause environmental difficulties such as depletion of ozone layer and greenhouse effect. thus, we must find substitutes for such refrigerants, in this paper, the effect of refrigerant on the thermodynamics performance of refrigeration cycles are studied. to do this, a refrigerator that has designed for r12, is simulated. results show that pure refrigerant r134a and mixture r32/r132b are convenient substitutes for r12.

متن کاملThermodynamic Analysis of the Irreversibilities in Solar Absorption Refrigerators
A thermodynamic analysis of the irreversibility on solar absorption refrigerators is presented. Under the hierarchical decomposition and the hypothesis of an endoreversible model, many functional and practical domains are defined. The effect of external heat source temperature on the entropy rate and on the inverse specific cooling load (ISCL) multiplied by the total area of the refrigerator A/...
متن کاملThermodynamic Properties of Muiticomponent Refrigerants
In recent years, increasing attention has been focused on the use ofhalogenated hydrocarbon mixtures as working fluids in vapor compressionrefrigeration systems, e.g. heat pumps. This paper discusses phase rules,applied to the equilibrium of the vapor and liquid states of such mixtures.Mixtures of ideal behavior, those that obey Raoult's law, and those withdeviations from th...
متن کاملPrediction of Thermodynamic Properties of Refrigerants in the Superheated Ragion
This paper demonstrates the capabilities of the PFGC-MES equation of state (EOS) for calculating the thermodynamic properties in the superheated region for pure refrigerants. In addition the ability of this EOS is also tested for predicting the VLE behavior of binary mixtures. For pure compounds several properties in the superheated region are predicted. The calculated results and the experimen...
