Energy and Exergy Analysis Of A Refrigeration VaporCompression Cycle In Various Climatic Conditions Using R۱۳۴a

In this research a study of refrigeration vapor compression cycle with various climatic conditions and using R۱۳۴a as refrigerant performed. Therange of refrigerant performance for main thermodynamic properties like temperature, pressure, enthalpy and entropy described. A comprehensivecombined ۴D diagram of P-T-s-h for R۱۳۴a provided in order to compare behavior of the selected refrigerant in assumed working and climatic condition.Subsequently the Coefficient of Performance (COP) for refrigeration (cooling procedure), heat pump (Heating procedure) and both heating and coolingin standard and actual conditions performed and described. Afterward EER, HRR and cycle Capacity provide, and finally, the minimum and maximumranges of thermodynamic properties of each state, for assumed values in different climatic conditions calculated and consequently, according to first andsecond law of thermodynamics, analyzing of Energy, irreversibility and Exergy Destruction Ratio (EDR) of the system components individually andwhole system described.
