چکیده مقاله:

In this research a study of refrigeration vapor compression cycle with various climatic conditions andusing R۴۰۷c as refrigerant performed. A methodology performed for consideration of thermodynamic statesof a compression cycle by ۲۵ steps. The range of refrigerant performance for main thermodynamicproperties like temperature, pressure, enthalpy and entropy described. A Comprehensive combined ۴Ddiagram of P-T-s-h situations and conditions of states for R۴۰۷c provided in order to compare behavior ofthe selected refrigerant in assumed working and climatic condition. Subsequently The Coefficient ofPerformance (COP) for refrigeration (cooling procedure), heat pump (Heating procedure) and both heatingand cooling in standard and actual conditions performed and described. Afterward EER, HRR and cycleCapacity provide, and finally, the minimum and maximum ranges of thermodynamic properties of eachstate, for assumed values and different climatic conditions calculated and described.
