Energy and Exergy Analysis Of A Refrigeration Vapor CompressionCycle In Various Climatic Conditions Using R۴۰۷c

In this research a study of refrigeration vapor compression cycle with various climatic conditions and using R۴۰۷c as refrigerantperformed. A methodology performed for consideration of thermodynamic states of a compression cycle by ۲۵ steps. The rangeof refrigerant performance for main thermodynamic properties like temperature, pressure, enthalpy and entropy described.A Comprehensive combined ۴D diagram of P-T-s-h situations and conditions of states for R۴۰۷c provided in order to comparebehavior of the selected refrigerant in assumed working and climatic condition.Subsequently The Coefficient of Performance (COP) for refrigeration (cooling procedure), heat pump (Heating procedure) andboth heating and cooling in standard and actual conditions performed and described.Afterward EER, HRR and cycle Capacity provide, and finally, the minimum and maximum ranges of thermodynamic propertiesof each state, for assumed values and different climatic conditions calculated and consequently, according first and second law ofthermodynamics, analyzing of Energy, irreversibility and Exergy Destruction Ratio (EDR) of the system components individuallyand whole system, totally described.
