Energy and Exergy Analysis Of A Refrigeration Vapor Compression Cycle In Various Climatic Conditions Using R۲۲

In this research a study of refrigeration vapor compression cycle with various climatic conditions and using R۲۲ as refrigerant performed. The range of refrigerant performance for main thermodynamic properties like temperature, pressure, enthalpy and entropy described. A comprehensive combined ۴D diagram of P-T-s-h for R۲۲ 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 cooling in standard and actual conditions performed and described. Afterward EER, HRR and cycle Capacity provide, and finally, the minimum and maximu m ranges of thermodynamic properties of each state, for assumed values at different climatic conditions calculated and consequently, according first and second law of thermodynamics, analyzing of Energy, irreversibility and Exergy Destruction Ratio (EDR) of the system components individually and whole system described.
