A thermodynamic model is used to analyze a transcritical carbon dioxide heat pump cycle integrating vortex tube. The objective prove that tube beneficial in raising efficiency. novelty of the current work lies implementing sophisticated operating with at high pressures or two-phase state. However, for all other components pump, commercial library (TIL) associated Dymola software simulate system. conventional validated determine feasibility TIL library. Then, analyzed test performance and effect different parameters under various conditions. Of discussed, hot exit pressure desuperheater glycol mass flow rate are most effective on heating capacity overall coefficient performance. Meanwhile, significantly controls temperature, yet, limitation. On hand, variation cold fraction shows insignificant changes temperature. final conclusion improved by maximum 43.7% when compared pump.
