Energy analysis of vortex tube integrated transcritical carbon dioxide compression refrigeration systems (VTITCCRS).

Résumé

A theoretical energy analysis for VTITCCRS with double compressors, which uses the ramming effect and heat exchanger operating in the Ranque Hilsch vortex tube to determine temperature separation, exhibits maximum deviation of (-) 7.065% from the available published results for this system. The percentage deviations for theoretical energy analysis of other systems such as VTITCCRS with single compressor and back pressure valve etc., considered in the research are quite less than this value. By integrating a vortex tube and using double compressors in the conventional transcritical carbon dioxide compression refrigeration system, about 50% enhancement in the coefficient of performance can be achieved. The results of the energy analysis can be helpful to design experimental test rigs of vortex tube integrated transcritical carbon dioxide refrigeration systems as it provides dimensions of the required vortex tube.
