چکیده مقاله:

In this research a study of refrigeration vapor compression cycle with various climatic conditions and usingR۴۱۰a as refrigerant performed. A methodology performed for consideration of thermodynamic states of acompression cycle by ۲۵ steps, named Zand's method. The range of refrigerant performance for mainthermodynamic properties like temperature, pressure, enthalpy and entropy described. A Comprehensivecombined ۴D diagram of P-T-s-h situations and conditions of states for R۴۱۰a provided in order to comparebehavior of the selected refrigerant in assumed working and climatic condition. Subsequently The Coefficientof Performance (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 cycle Capacityprovide, and finally, the minimum and maximum ranges of thermodynamic properties of each state, forassumed values and different climatic conditions calculated and described.
