AB - In this paper, the Ranque-Hilsch vortex tube (RHVT) aided vapor compression  cooling (RHVTC) system and single vapor compression cooling (VCC) system were  designed and evaluated by using energy, exergy and economic analysis. The  cooling systems were designed for 3 different evaporator temperature and  different compressor discharge pressures which were available for  refrigerants. The highest value of net present value (NPV) of RHVTC system  was calculated as 35836 €. The helical vortex generator of J, 2st RHVT body,  control valve angle of 300, 2nd control valve opening position, R-143a were  used in this RHVTC system and the operating conditions of this system were T1  of 277.15 K, P2 of 1700 kPa and P8 of 601.325 kPa. For the same system, the  COP was calculated as 0.0347 and 0.0409 while exergy efficiency was  calculated as 0.0097 and 0.0079 for the summer and winter modes,  respectively.
