ABSTRACT

In this study, the Ranque-Hilsch vortex tube (RHVT) aided hybrid cooling - drying system was investigated by the energy analysis. In this aim, many systems were designed and evaluated with net present value (NPV) in the viewpoint of Life Cycle Cost (LCC). The RHVT experiments were performed for 9 different helical vortex generators, 3 different control valve angel (α=300, 450, 600), 3 different vortex tube body, 5 different opening position of the control valve and 5 different inlet flow pressure (201.325-601.325 kPa). The maximum energy efficiency of RHVT aided hybrid cooling - drying system was determined as 0.160 and 0.146 for the summer mode ( ambient temperature of 306.15 K) and winter mode ( ambient temperature of 289.15 K), respectively. NPV of this hybrid system was calculated as 816.08 €. The highest value of NPV was calculated as 35,784.39 € for the helical vortex generator of 0, control valve angle of 300, and the 1st type of RHVT body.
