Abstract
In this paper, the Ranque-Hilsch vortex tube aided vapor compression cooling (RHVTC) system and single vapor compression cooling system were designed and evaluated by using energy, exergy, and economic analysis. The cooling systems were designed for three different evaporator temperature and different compressor discharge pressures which were available for refrigerants. The highest value of net present value of Ranque-Hilsch vortex tube system was calculated as 35836 €. The helical vortex generator of J-type, 1st Ranque-Hilsch vortex tube body, control valve angle of 30°, 2nd control valve opening position, R-143a were used in this Ranque-Hilsch vortex tube 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.
