Dataset of Comprehensive Thermal Performance on Cooling the Hot Tube Surfaces of Vortex Tube at Different Pressure and Fraction

摘要

The performance of the vortex tube is low compared to a conventional heat pump engine based on Freon refrigerants, and therefore, there is a need for an experiment on how to improve its efficiency. This data article aims to analyze the effect of the new vortex tube design on cold temperature (Tc), hot temperature (Th), delta cold temperature (ΔTc), delta hot temperature?(ΔTh), heat transferred as cooling effect(Q˙c), heat transferred as heating effect(Q˙h), isentropic efficiency as cooling effect (ηisc), isentropic efficiency as heating effect (ηisc), the coefficient of performance refrigeration (COPref), and coefficient of performance heat pump (COPh), which is tested based on pressure and fraction variations. The data were obtained from the experimental measurements. Data were collected at conditions with temperature controlled at 27 ± 0.1°C. All measuring instruments were supposed to be consistent for at least 5 min for data to be collected, although retrieval was conducted 4 times.
