چکیده مقاله:

In this research a study of refrigeration vapor compression cycle with various climatic conditions and usingR۱۳۴a 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 Comprehensive combined ۴D diagram of P-T-s-h situations and conditions of states for R۱۳۴a provided inorder 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 maximum ranges ofthermodynamic properties of each state, for assumed values and different climatic conditions calculated anddescribed.
